The percent decrease in the number of people who went to the pool over these four weeks is 15%.

A percentage is a value or ratio that may be stated as a fraction of 100. If we need to calculate a percentage of a number, we should divide it's entirety and then multiply it by 100.

The number of people by the fourth week will be:

= 1060 - 105 + 145 - 199

= 901

The percentage decrease will be:

= (1060 - 901) / 1060 × 100

= 159/1060 × 100

The average rate of change of the function f(x) from x = 1 to x = 2 is, -3.75 when the function f(x)=20(1/4)ˣ.

Given that,

We have to find what is the function f(x)=20(1/4)ˣ average rate of change from x = 1 to x = 2.

We know that,

Average rate of change(A(x)) of f(x) over a interval [a,b] is given by:

A(x)=(f(b)-f(a))/b-a

We get the function:

f(x)=20(1/4)ˣ

Now, the average rate of change from x = 1 to x= 2

At x = 1

Then;

f(1)=20(1/4)¹=5

At x = 2

Then;

f(2)=20(1/4)²=1.25

Substitute these in above formula we have;

A(x)=f(2)-f(1)/2-1=-3.75

Therefore, The average rate of change of the function f(x) from x = 1 to x = 2 is, -3.75 when the function f(x)=20(1/4)ˣ.

Christopher's statement "whenever you multiply a whole number by a fraction the product is either greater or less than the whole number" is correct.

A fraction is a way to describe a part of a whole. such as the fraction ¼ can be described as 0.25.

The statement made by Christopher is correct, this is because a fraction is always either greater or lesser than 1. And multiplying a fraction to a whole number will give result either greater or less than the whole number, depending upon the type of fraction it is.

For example let's take the number 100,

Let's take a proper fraction, 2/5. Therefore, the result will be,

100 × (2/5) = 40

Let's take an improper fraction, 7/5. Therefore, the result will be,

100 × (7/5) = 140

Answer:

x = 0.6 , x = 2

Step-by-step explanation:

the absolute value function always gives a positive value, that is

| - a | = | a | = a

the expression inside the bars, however , can be positive or negative, so

9 - 8x = 2x +3 ( subtract 2x from both sides )

9 - 10x = 3 ( subtract 9 from both sides )

- 10x = - 6 ( divide both sides by - 10 )

x = 0.6

Or

- (9 - 8x) = 2x + 3

- 9 + 8x = 2x + 3 ( subtract 2x from both sides )

- 9 + 6x = 3 (add 9 to both sides )

6x = 12 ( divide both sides by 6 )

x = 2

As a check

substitute these values into the equation and if both sides are equal then they are the solutions.

x = 0.6

left side = | 9 - 8(0.6) | = | 9 - 4.8 | = | 4.2 | = 4.2

right side = 2(0.6) + 3 = 1.2 + 3 = 4.2= left side

-------------------------------------------------------

x = 2

left side = | 9 - 8(2) | = | 9 - 16 | = | - 7 | = 7

right side = 2(2) + 3 = 4 + 3 = 7 = left side

the solutions to the equation are x = 0.6 and x = 2

No the results did not deviate significantly from what would be expected due to chance.

The standard deviation is a statistic that expresses how much variance or dispersion there is in a group of numbers. While a high standard deviation suggests that the values are dispersed throughout a larger range, a low standard deviation suggests that the values tend to be near to the established mean. The term "standard deviation" (or "") refers to a measurement of the data's dispersion from the mean. A low standard deviation implies that the data are grouped around the mean, whereas a large standard deviation shows that the data are more dispersed.

We have to find how we prove QR≅SR.

As we can see that;

PQ = PS

Since PR is bisector.

So PR is common in both triangles PRQ and PRS.

PR=PR

Since PR is bisector.
