In a wilflife park 30% of big cats are lions and 70% are tigers
Answers
In the wildlife park, if 30% of the big cats are lions and 70% are tigers, we can determine the proportion of each type of big cat in relation to the total number of big cats.
Let's assume there are 100 big cats in the park.
30% of 100 is (30/100) * 100 = 30. So, there are 30 lions in the park.
Similarly, 70% of 100 is (70/100) * 100 = 70. So, there are 70 tigers in the park.
Therefore, out of the 100 big cats in the wildlife park, there are 30 lions and 70 tigers.
To summarize:
The proportion of lions is 30 out of 100, which can be expressed as 30/100 or 3/10.
The proportion of tigers is 70 out of 100, which can be expressed as 70/100 or 7/10.
Please note that the actual number of big cats in the wildlife park may vary; this calculation is based on the assumption of 100 big cats for illustrative purposes.

1. According to the podcast, why and how is chicken the reason American trucks dominate the truck market in the United States? Briefly explain. 2. Name two reasons a party (e.g., a politician or an industry association) may want to impose a tariff? 3. Who are they usually trying to protect? Who would be hurt by a tariff on automobiles? Explain. 4. Describe how competition encourages innovation? In your answer to this question, include a discussion on why American trucks "basically stayed the same over the years. 5. Describe ways foreign companies tried to get around American-imposed tariffs on automobiles. 6. Do you think the methods you described in your previous answer are efficient for an economy? Why or why not? 7. Lastly, how can a tariff be used as a bargaining chip? In your opinion, is that a good reason to impose tariffs - why or why not?
Answers
1. Chicken became the key product that drove the creation of the Interstate Highway System, which led to the dominance of American trucks in the US truck market.
2. A party may want to impose a tariff to protect domestic industries from foreign competition or to generate revenue for the government.
3. A party is usually trying to protect domestic industries, but a tariff on automobiles would hurt both domestic consumers who would pay higher prices and foreign producers who would face reduced demand.
4. Competition encourages innovation by providing incentives for companies to improve their products and services to stay ahead of their rivals; American trucks stayed the same because they faced little competition due to protectionist policies.
5. Foreign companies tried to get around American-imposed tariffs on automobiles by establishing factories in the US, forming joint ventures with American companies, or exporting through third countries.
6. The methods used to get around tariffs can be efficient in the short term, but they may not be sustainable or desirable in the long term as they can lead to trade imbalances and undermine the competitiveness of domestic industries.
7. Tariffs can be used as a bargaining chip to negotiate better trade deals, but they should be imposed judiciously and only as a last resort to avoid damaging the economy and harming consumers.
1. In the podcast, chicken is cited as the reason why American trucks dominate the truck market in the United States.
This is because in the 1960s, the government imposed regulations on the trucking industry that limited the amount of weight a truck could carry.
To get around these regulations, the industry started using smaller trucks to transport goods, which were often not strong enough to handle the weight.
However, they found that if they put chicken on the back of the trucks, the weight of the cargo would distribute more evenly and the smaller trucks could handle the load.
This led to the development of the modern pickup truck, which is now a staple of the American automobile market.
2. Parties may want to impose tariffs for various reasons, such as to protect domestic industries and jobs from foreign competition, to raise revenue for the government, or to level the playing field in international trade.
Two specific reasons for imposing tariffs could be to protect national security interests or to address unfair trade practices by other countries.
3. Tariffs are usually imposed to protect domestic industries and jobs, and the parties that are being protected are typically the producers of the goods or services in question.
However, tariffs can also harm consumers who may have to pay higher prices for imported goods or may have fewer choices in the marketplace. For example, if a tariff is imposed on automobiles, domestic car manufacturers may benefit, but consumers may have to pay more for cars, and foreign automakers may lose market share.
4. Competition encourages innovation by creating incentives for companies to improve their products or services to gain a competitive advantage.
In the case of American trucks, the lack of competition may have contributed to their lack of innovation over the years. Since they dominated the market, there was little pressure to improve or innovate, and as a result, they have largely stayed the same.
However, the rise of foreign competition in recent years has led American truck manufacturers to invest more in innovation to stay competitive.
5. Foreign companies have tried to get around American-imposed tariffs on automobiles in various ways, such as by moving production to countries not subject to the tariffs, by exporting parts and assembling them in the United States, or by lobbying the government for exemptions or tariff reductions.
6. The methods used by foreign companies to get around tariffs may not be efficient for the economy as a whole because they can lead to higher costs and inefficiencies in the supply chain.
However, they may be necessary for individual companies to remain competitive in the short term.
Ultimately, a more efficient solution would be to address the root causes of the trade imbalances that lead to tariffs in the first place.
7. A tariff can be used as a bargaining chip by threatening to impose tariffs on imports from a country unless they make concessions in trade negotiations.
While this can be an effective strategy in certain situations, it can also lead to a trade war and harm both economies.
In general, tariffs should be used sparingly and as a last resort, and efforts should be made to address underlying trade issues through diplomacy and negotiation.

Option 1:\(y = -\frac{2}{3}x+5\) is the correct answer.
Step-by-step explanation:
The slope-intercept form of a line is given as:
\(y = mx+b\)
Here m is the slope and b is the y-intercept
m is calculated using the formula
\(m = \frac{y_2-y_1}{x_2-x_1}\)
Given points are:
\((x_1,y_1) = (-3,7)\\(x_2,y_2) = (9,-1)\)
Putting the values in the formula
\(m = \frac{-1-7}{9+3}\\= \frac{-8}{12}\\=\frac{-2}{3}\)
Putting m=-2/3 in equation
\(y= -\frac{2}{3}x+b\)
Putting (9,-1) in equation
\(-1 = -\frac{2}{3}(9)+b\\-1 = -6+b\\b = -1+6\\b = 5\)
Putting the value of b
\(y = -\frac{2}{3}x+5\)

What is the Pythagorean Theorem?The Pythagorean Theorem states that in a right-angled triangle, the square of the length of the hypotenuse (the longest side) is equal to the sum of the squares of the lengths of the other two sides.
The theorem is expressed as follows:
c² = a² + b².
In which:
c is the length of the hypotenuse.a and b are the lengths of the other two sides (the legs) of the right-angled triangle.Considering an equilateral triangle, in which all the side lengths are of 4, we have a right triangle in which:
The sides are 2 cm and the height h.The hypotenuse is of 4 cm.Hence the height is obtained as follows:
h² + 2² = 4²
h² = 12
\(h = \sqrt{3 \times 4}\)
\(h = 2\sqrt{3}\) cm
The area of a triangle is given as half the multiplication of the base and of the height, hence:
\(A = 0.5 \times 4 \times 2 \sqrt{3}\)
\(A = 4\sqrt{3}\) cm².

Since previous studies have reported that elite athletes are often deficient in their nutritional
intake (e.g., total calories, carbohydrates, protein), a group of researchers decided to evaluate
Canadian high performance athletes. A total of n = 324 athletes from eight Canadian sports
centers participated in the study. One reported finding was that the average caloric intake
among the n=201 women was 2403.7 kcal/day. The recommended amount is 2811.5 kcal/day.
Is there evidence that female Canadian athletes are deficient in the caloric intake? (Assume
?=0.05 and the data comes from a normal population)
a. State the appropriate null and alternative hypotheses to test this.
b. Which n should be used (201 or 324)? What key word in the last sentence of the paragraph
above led you to this decision?
c. Assuming a population standard deviation of 880 kcal/day, what is the value of the test
statistic?
d. Sketch the normal curve, label your test statistic and shade the appropriate area related to
the p-value.
e. What is the p-value?
f. Do you reject or fail to reject the null hypothesis? Why?
g. Write a conclusion in terms of language related to the given problem.
Answers
a. Null hypothesis (H0): The average caloric intake among female Canadian athletes is equal to or greater than the recommended amount (µ ≥ 2811.5 kcal/day).
Alternative hypothesis (H1): The average caloric intake among female Canadian athletes is less than the recommended amount (µ < 2811.5 kcal/day).
b. The value of n that should be used is 201
c. SEM = 880 / √201
d. To sketch the normal curve and label the test statistic, we need the test statistic value and the critical region corresponding to the significance level α = 0.05
e. Without the test statistic or critical region, we cannot calculate the p-value.
f. Since we don't have the test statistic, critical region, or p-value, we cannot make a decision to reject or fail to reject the null hypothesis at this point.
g. Without the test statistic, critical region, or p-value, we cannot draw a conclusion regarding the evidence for or against the deficiency in caloric intake among female Canadian athletes.
a. The appropriate null and alternative hypotheses to test whether female Canadian athletes are deficient in caloric intake can be stated as follows:
Null hypothesis (H0): The average caloric intake among female Canadian athletes is equal to or greater than the recommended amount (µ ≥ 2811.5 kcal/day).
Alternative hypothesis (H1): The average caloric intake among female Canadian athletes is less than the recommended amount (µ < 2811.5 kcal/day).
b. The value of n that should be used is 201, which represents the number of female athletes in the study. The key word in the last sentence of the paragraph ("n=201 women") indicates that the information provided specifically pertains to the female athletes, not the entire sample of 324 athletes.
c. To calculate the test statistic, we need to determine the standard error of the mean (SEM) using the formula:
SEM = σ / √n
where σ is the population standard deviation and n is the sample size. In this case, the population standard deviation is given as 880 kcal/day, and the sample size is 201.
SEM = 880 / √201
d. To sketch the normal curve and label the test statistic, we need the test statistic value and the critical region corresponding to the significance level α = 0.05. However, the critical region is not provided in the given information.
e. The p-value represents the probability of obtaining a test statistic as extreme as or more extreme than the observed value, assuming the null hypothesis is true. Without the test statistic or critical region, we cannot calculate the p-value.
f. Since we don't have the test statistic, critical region, or p-value, we cannot make a decision to reject or fail to reject the null hypothesis at this point.
g. Without the test statistic, critical region, or p-value, we cannot draw a conclusion regarding the evidence for or against the deficiency in caloric intake among female Canadian athletes. Further analysis is required to obtain the missing information and make a conclusive statement.

Answers
The 90% confidence interval for the difference in the population means is -2.51 to 0.31
Calculating the 90% confidence interval for the population mean differenceFrom the question, we have the following parameters that can be used in our computation:
xˉ₁ = −17.1
s₁² = 8.4
n₁ = 22
xˉ₂ = −16.0
s₂² = 8.7
n₂ = 24
Calculate the pooled variance using
P = (df₁ * s₁² + df₂ * s₂²)/df
Where
df₁ = 22 - 1 = 21
df₂ = 24 - 1 = 23
df = 22 + 24 - 2 = 44
So, we have
P = (21 * 8.4 + 23 * 8.7)/44
P = 8.56
Also, we have the standard error to be
SE = √(P/n₁ + P/n₂)
So, we have
SE = √(8.56/22 + 8.56/24)
SE = 0.86
The z score at 90% CI is 1.645, and the CI is calculated as
CI = (x₁ - x₂) ± z * SE
So, we have
CI = (-17.1 + 16.0) ± 1.645 * 0.86
This gives
CI = -1.1 ± 1.41
Expand and evaluate
CI = (-2.51, 0.31)

Shalane notices that the ready meals she buys at the shop now have '40% LESS SALT' written across the pack. She notices that the salt content of the pack is now 5 g. What was the salt content of the ready meals she bought before the salt content was reduced?
Answers
Answer:
8.33 grams
Step-by-step explanation:
If the ready meals now have "40% LESS SALT" and the current salt content is 5 g, we can determine the previous salt content by calculating the amount that represents 100% of the original value.
Let's assume the previous salt content was x grams.
According to the information provided, the current salt content is 40% less than the previous amount. This means the current salt content is 60% (100% - 40%) of the previous amount.
Mathematically, we can express this as:
0.6x = 5
To find x, we can divide both sides of the equation by 0.6:
x = 5 / 0.6
Evaluating the expression:
x ≈ 8.33 grams
Therefore, the salt content of the ready meals before the reduction was approximately 8.33 grams.

Assume that demand for a commodity is represented by the equation
P = -2Q-2Q_d
Supply is represented by the equation
P = -5+3Q_1
where Q_d and Q_s are quantity demanded and quantity supplied, respectively, and Pis price
Instructions: Round your answer for price to 2 decimal places and enter your answer for quantity as a whole number Using the equilibrium condition Q_s = Q_d solve the equations to determine equilibrium price and equilibrium quantity
Equilibrium price = $[
Equilibrium quantity = units
Answers
The equilibrium price is $0 and the equilibrium quantity is 5 units.
To find the equilibrium price and quantity, we need to set the quantity demanded equal to the quantity supplied and solve for the equilibrium values.
Setting Q_d = Q_s, we can equate the equations for demand and supply:
-2Q - 2Q_d = -5 + 3Q_s
Since we know that Q_d = Q_s, we can substitute Q_s for Q_d:
-2Q - 2Q_s = -5 + 3Q_s
Now, let's solve for Q_s:
-2Q - 2Q_s = -5 + 3Q_s
Combine like terms:
-2Q - 2Q_s = 3Q_s - 5
Add 2Q_s to both sides:
-2Q = 5Q_s - 5
Add 2Q to both sides:
5Q_s - 2Q = 5
Factor out Q_s:
Q_s(5 - 2) = 5
Q_s(3) = 5
Q_s = 5/3
Now that we have the value for Q_s, we can substitute it back into either the demand or supply equation to find the equilibrium price. Let's use the supply equation:
P = -5 + 3Q_s
P = -5 + 3(5/3)
P = -5 + 5
P = 0
Therefore, the equilibrium price is $0 and the equilibrium quantity is 5 units.
