ANSWER

EXPLANATION

We want to find the probability that the average of all participants in the study was fewer than 10,200 breaths each night.

To do this, first, we have to find the z-score corresponding to the sample mean:

where x = sample mean

μ = population mean

σ = standard deviation

n = sample size

Therefore, the z-score is:

Now, using the standard normal table, we can find P(z < 1.01).

Therefore, the probabilityis:

That is the answer.

Maintaining a balanced budget while influencing the output level of the economy is not necessarily macroeconomically neutral and requires careful consideration of the policy trade-offs involved.

The problem presents a scenario where governments aim to maintain a balanced budget while trying to influence the output level of the economy through changes in government spending (g) and taxes (t). To assess the macroeconomic neutrality of such policy changes, we use equation (3.8) to find the impact of a unit increase in g and t on the output level y.

(a) The impact of a unit increase in g on the output level y is given by the multiplier (1/1-c1), where c1 is the marginal propensity to consume. Therefore, an increase in g by one unit will increase output by the multiplier times the change in g.

(b) The impact of a unit increase in t on the output level y is given by the negative multiplier (-c1/1-c1). Therefore, an increase in t by one unit will decrease output by the negative multiplier times the change in t.

(c) The answers to (a) and (b) are different because an increase in g will increase aggregate demand, leading to a higher equilibrium level of output, while an increase in t will decrease disposable income and hence decrease consumption and aggregate demand, leading to a lower equilibrium level of output.

In the scenario where the government starts with a balanced budget, any increase in government spending will have to be financed through an increase in taxes or a reduction in government transfers. The impact of such policy changes on the output level will depend on the size of the multiplier and the extent to which the increase in taxes or reduction in transfers affects consumption and aggregate demand.

The probability of a home for sale having a garage but no pool is 0.42.

To do this, we need to use some probability rules. One useful rule is the formula for calculating the probability of an event not occurring. This is given by:

P(not A) = 1 - P(A)

where A is the event we are interested in, and not A is the event of A not occurring.

In this case, we are interested in the probability of a home having a garage but no pool. Let's call this event GNP (short for garage no pool). Using the information given, we know that 60% of homes have garages and 18% have both garages and pools. We can use this information to calculate the probability of a home having a garage but no pool as follows:

P(GNP) = P(G) - P(G and P)

where G is the event of a home having a garage and P is the event of a home having a pool.

Substituting the values we have:

P(GNP) = 0.6 - 0.18

P(GNP) = 0.42

Answer: y = -6x + 4.5

Step-by-step explanation:

to put it into slope intercept form use the standard form y=mx+b

where m is the slope and b is the y intercept

First, we have to find the slope

the slope is found using (y1-y2)/(x1-x2)

so you have 10.5-4.5 over -1-0 or 6 over -1

So the slope is -6

Second, we have to use a given Y value for the intercept

y = -6x + 4.5

Answer:

b = 35

Step-by-step explanation:

Use the butterfly method (Cross multiply):

Thus, the mass of the frog is 48.6π grams when it is in a hemispherical pod which just floats without sinking into sea water.

The force imposed on a body by a fluid, such as water or air, in which the body is submerged or immersed is known as buoyancy. This force is equivalent to the mass of the fluid that the body has displaced. In mathematics, buoyancy is defined as the sum of the fluid density, gravitational acceleration, and body volume. Archimedes' principle, which asserts that the buoyant force on an item is equal to the weight of the fluid it displaces, is a name for this connection. A key idea in the study of fluid mechanics, buoyancy has many uses, including the construction of boats, planes, and other floating structures.

How to solve?

V = 2/3 * π * r^3,

V = 2/3 * π * 6^3 = 2/3 * π * 216 = 36π.

F = V * d,

F = 36π * 1.35g/c * m^3 = 48.6π g.

F = m + W,

48.6π g = m + 0 g.

m = 48.6π g.

The type of hypothesis test to be used in this scenario is a one-sample t-test with a two-tailed alternative hypothesis.

The problem is asking to conduct a hypothesis test to determine whether the bag filling machine works correctly at the 433 gram setting.

The hypothesis test would involve a null hypothesis (H0) and an alternative hypothesis (Ha).

The null hypothesis is typically the hypothesis of "no effect" or "no difference" and is denoted as H0. In this case, the null hypothesis would be that the mean weight of potato chips in the bags filled by the machine at the 433 gram setting is equal to 433 grams. Therefore, the null hypothesis would be:

H0: μ = 433

The alternative hypothesis (Ha) is the hypothesis that we want to test, and it is denoted as Ha. In this case, the alternative hypothesis would be that the mean weight of potato chips in the bags filled by the machine at the 433 gram setting is not equal to 433 grams. Therefore, the alternative hypothesis would be:

Ha: μ ≠ 433

To conduct the hypothesis test, we would need to calculate the test statistic and compare it to the critical value. Since the sample size is large (n=301) and the population variance is unknown, we would use a t-test with a level of significance of 0.02.

If the calculated t-value falls outside the critical t-value, we would reject the null hypothesis and conclude that the bag filling machine does not work correctly at the 433 gram setting.

If the calculated t-value falls within the critical t-value, we would fail to reject the null hypothesis and conclude that there is not enough evidence to suggest that the bag filling machine does not work correctly at the 433 gram setting.

The sample of students who buy hot lunch on a particular day may not be considered a random sample. The explanation lies in the fact that this sample is limited to a specific group of students who have opted for hot lunch, excluding those who bring their own lunch or choose not to eat in the cafeteria.

Random sampling involves selecting individuals from a population in such a way that every member has an equal chance of being chosen. However, by surveying only those students who buy hot lunch on a particular day, the sample is limited to a specific subset of the population. This excludes students who bring their own lunch or choose not to eat in the cafeteria.

By targeting a specific group, the sample may introduce bias and not accurately represent the entire student population's opinion on the quality of food in the school cafeteria. To achieve a random sample, it would be necessary to include students who bring their own lunch or have meals outside the cafeteria to ensure a more comprehensive and unbiased representation.

Step-by-step explanation:

Using the remainder theorem when , when the value of x + 2 is substituted into the polynomial if it's a factor it will produce a result of zero else any number will prove that it's not a factor.

So we have

x = - 2

Substitute the value of x into the polynomial

That's

\(p( - 2) = 2 ({ - 2})^{4} + 6( { - 2})^{3} - 5( - 2) - 10 \\ = 2(16) + 6( - 8) + 10 - 10 \\ = 32 - 48 \\ = - 16\)

Answer:

The cost of one taco is $0.87 and the cost of one enchilada is $1.16

Step-by-step explanation:

Let the cost of tacos be X

and cost of enchiladas be y

So, by using given data, we have following equations

3X + 2Y = 4.93             (1)

2X + 4Y = 6.38             (2)

So, first multiply 1st equation by 2 and 2nd equation by 3, then subtracting 1st equation by 2nd.

= 2 × ( 3X + 2Y = 4.93)       (1)

= 3 × (2X + 4Y = 6.38)        (2)

= - (6X + 4Y = 9.86)              (1)

= 6X + 12y = 19.14            (2)

= 8Y = 9.28

Y = 9.28 ÷ 8 = 1.16

By putting the value of Y in equation 1, we get

3X + 2(1.16) = 4.93

3X + 2.32 = 4.93

X = 2.61 ÷ 3 = 0.87

Hence, the cost of one taco is $0.87 and the cost of one enchilada is $1.16.

When specializing in the goods they have a comparative advantage in, you will produce 36 pounds of apples and your neighbor will produce 16 pounds of cherries. After trading half of your production for half of your neighbor's, you will end up consuming 18 pounds of apples and 8 pounds of cherries, while your neighbor will consume 18 pounds of cherries and 4 pounds of apples.

To find the production levels when specializing, we need to identify the goods each party has a comparative advantage in. You produce 72 pounds of apples and 12 pounds of cherries when focusing solely on each good, while your neighbor produces 32 pounds of both apples and cherries. You have a comparative advantage in apples since you can produce 6 times more apples than cherries (72 apples vs. 12 cherries) while your neighbor can only produce twice as many apples as cherries (32 apples vs. 16 cherries).

Thus, you will specialize in apple picking, and your neighbor will specialize in cherry picking. As a result, you will produce 36 pounds of apples, and your neighbor will produce 16 pounds of cherries. After trading, you both end up with half of each other's production. You will consume 18 pounds of apples and 8 pounds of cherries, while your neighbor will consume 18 pounds of cherries and 4 pounds of apples. This specialization and trade allow both of you to enjoy a more diverse consumption bundle and increase overall welfare.

The directrix of the given equation is x = -4.

The focus of the given equation is (0, 2).

To identify the directrix and focus of the given equation, we can use the formula for a parabola in standard form, which is (y - k)^2 = 4p(x - h),

where (h, k) is the vertex and p is the distance from the vertex to the directrix and focus.

In this case, the equation (y - 2)^2 = 8(x + 2) is already in the standard form. Comparing it with the general form, we can see that the vertex is (-2, 2).

To find the value of p, we need to rewrite the equation in the standard form by dividing both sides by 8:

(y - 2)^2/8 = (x + 2)

Now we can compare it with the standard form and see that p = 2. Since p is positive, the parabola opens to the right.

The directrix is a vertical line, and it is a distance of p = 2 to the left of the vertex. Therefore, the equation of the directrix is x = -4.

The focus is a point on the axis of symmetry and is also a distance of p = 2 to the right of the vertex. To find the coordinates of the focus, we add p = 2 to the x-coordinate of the vertex: -2 + 2 = 0. So the focus is located at (0, 2).

In summary:
- The directrix of the given equation is x = -4.

Answer:

Let $10 tickets be (x)

Let $15 tickets be (y)

Now we know they sold 1000 tickets

And they earned 12,200 from sales

So we can say

X+Y=1000

10x+15y=12,200

We can do substitution

So lets find Y first

Y=1000-x (basically x+y=1000 but solved for Y)

10x+ 15 ( 1000-x)= 12,200

You’d get

10x+15000-15x=12200

Combine and solve for x and you’ll get

x=560

So we know that x is 560

We can just use that to solve for Y

Since X is 560 tickets

And 1000 tickets soled

1000-560=440

440 ($15) tickets

560 ($10) tickets
