Problem 1:90;48,42;16,32,28,14

Problem 2:180;60,120;12,48,30,90

Step-by-step explanation:

Problem 1:

There are 90 pupils at a primary school,so the first number is 90

48 of the pupils are girls, so the number of boys is 90-48=42

\(\frac{1}{3}\) of the girls  play football, so the number of girls  who plays football is \(\frac{1}{3} \times48=16\),the number of girls  who does not play football is48-16=32

\(\frac{2}{3}\) of the boys play football,so the number of boys  who plays football is \(\frac{2}{3} \times42=28\),the number of boys  who does not play football is 42-28=14

Problem 2:

There are 180 apples in a grocery store,so the first number is 180

\(\frac{1}{3}\)of the apples are red,so the number of red apples is \(180\times\frac{1}{3} =60\)

,the number of green apples is 180-60=120. \(\frac{1}{5}\) of the red applesare bruised,\(\frac{1}{5} \times60=12\),so the number of red apples not bruised is 60-12=48.   \(\frac{1}{4}\) of the green apples are bruised,\(120\times\frac{1}{4} =30\),so the number of green  apples not bruised is 120-30=90.

Hi there!

For a line to be PARALLEL, it must contain the same slope.

The given line has a slope of 4, so we can use the point-slope formula to solve:

\(\large\boxed{y - y_1 = m(x - x_1)}\)

y1 = y-coordinate of given point

x1 = x-coordinate of given point

m = slope

Plug in the values:

\(y - 1 = 4(x - (-2))\\\\y - 1 = 4(x + 2)\)

Simplify:

\(y - 1 = 4x + 8\\\\\boxed{y = 4x + 9}\)

In an incidence geometry with the additional axiom that every line has exactly three points lying on it, the minimum number of points required is 4.

This is because a line must have at least two-points to exist, and if it has only two points, it is not possible to have another point lying on it (since every line must have exactly three points).

Hence, there must be at least 4-points to create two lines such that each line contains exactly three points.

Also, with 4 points, it is possible to create 6 lines such that each line contains exactly 3 points, forming a configuration known as the Fano-plane, which is the smallest example of an incidence geometry that satisfies the given axiom.

Step-by-step explanation:

It is important in the definition of logarithm that the base of the logarithm does not equal 1 because log base 1 is undefined and leads to mathematical inconsistencies.

The logarithm of a number is defined as the exponent to which a specific base must be raised to obtain that number. However, when the base of the logarithm is equal to 1, the definition becomes problematic.

If the base of the logarithm is 1, we have log₁(x) = y, where 1^y = x. Since any number raised to the power of 0 equals 1, we would have 1^0 = x, which implies that x equals 1 for all values of x. This creates a contradiction, as it would suggest that all numbers are equal to 1, which is not true.

To avoid this inconsistency, the definition of logarithms excludes the base 1. By excluding 1 as a possible base, logarithmic functions maintain their essential properties, such as the logarithmic identities and the relationship between exponentiation and logarithms.

Therefore, the restriction that the base of the logarithm cannot equal 1 is necessary to ensure mathematical consistency and clarity in the definition of logarithmic functions. It helps prevent mathematical contradictions and allows logarithms to be defined in a meaningful and consistent manner.

Step-by-step explanation:

The average percentage change in population in California from 2000-2009 is 1.35% and population in 2015 will be 39306963.

What is average?

In mathematics, the average is a value that represents the central or typical value in a set of numbers. There are several types of averages, including the mean, median, and mode.

The mean is the most commonly used type of average, and it is calculated by adding up all the numbers in a set and then dividing the sum by the total number of numbers. For example, the mean of the set {3, 5, 8, 12} can be calculated as:

mean = (3 + 5 + 8 + 12) / 4 = 7

Now,

To calculate average of percentage change from 2000-2009

we have to add percentage change for every year

and that will be = 1.97+1.71+1.65+1.42+1.22+1.02+1.07+1.22+0.93

=12.21%

then average=12.21/9=1.35%

hence,

          The average percentage change in population in California from 2000-2009 is 1.35%.

The population in 2015 will be = 37000000 + (1.35)⁶ × 37000000/100

=37000000+2306963.15

Based on the characteristics of the distribution, the probability that the first goal is scored in less than 4 minutes is 0.

For us to be able to calculate the probability that the first goal is scored in less than 4 minutes, the distribution needs to satisfy the requirements of the Central Limit Theorem(CLT).

Based on the fact that the distribution here is extremely right skewed, then it does not satisfy the requirements of CLT so the probability is 0.

Answer:

length = 10 in, width = 6 in

Step-by-step explanation:

Let the width be x.

Then, length = (x+4)

Area = 60 in²

Area of a rectangle = width × length

60 = x × (x+4)

60 = x² + 4x

x² + 4x - 60 = 0

Splitting the middle term :-

x² + 10x - 6x - 60 = 0

x (x + 10) - 6 ( x + 10) =0

(x + 10) ( x - 6)

x = -10 (doesn't fulfill our requirement)

x = 6

So, width = 6 in

length = 6+4 = 10 in

The probability of getting more than 5 questions right in the quiz is

0.00011445.

Given, the probability of guessing right on a 4-option multiple choice item is 1/4 or 0.25.

A quiz contains 10 questions.

we have to find the probability of getting more than 5 right.

Required Probability = P(X = 6) + P(X = 7) + P(X = 8) + P(X = 9) + P(X = 10)

Required Probability = (1/4)^6(3/4)^4 + (1/4)^7(3/4)^3 + (1/4)^8(3/4)^2 + (1/4)^9(3/4)^1 + (1/4)^10

Required Probability = 0.000077 + 0.000025 + 0.0000086 + 0.0000029 + 0.00000095

Required Probability = 0.00011445

Answer:

Step-by-step explanation:

The company should survey at least 601 customers to be 95% confident that the estimated proportion is within 4 percentage points of the true population proportion.

To determine the sample size needed, we can use the formula:

n = (z^2 * p * (1-p)) / E^2

where:

n is the sample size needed

z is the z-score for the desired confidence level (in this case, 1.96 for 95% confidence)

p is the estimated population proportion (we don't have an estimate, so we'll use 0.5, which gives the largest possible sample size)

E is the maximum margin of error (4 percentage points in this case, or 0.04)

Plugging in the values, we get:

n = (1.96^2 * 0.5 * 0.5) / 0.04^2

n = 600.25

We round up to the nearest whole number to get a sample size of 601.

This means that if the company surveys 601 randomly selected customers and finds that, for example, 60% of them keep up with regular vehicle maintenance, we can be 95% confident that the true proportion of all customers who keep up with regular vehicle maintenance is between 56% and 64%.
