We are given the diameter of the circle, I assume. In this case, the formula of the area of the circle is expressed as A = pi d^2/4. where pi is a constant. The only option taht makes sense here is C. 6.25 in2. This should have the constant pi on it.

we know that

the area of the circle is equal to

A=\pi r^{2}

where

r is the radius of the circle

In this problem we have

Diameter=5\ in\\r=Diameter/2\\r=5/2\\r=2.5\ in

substitute the value of r in the area's formula

A=\pi*2.5^{2}

A=6.25\pi\ in^{2}

therefore

<u>the answer is</u>

6.25\pi\ in^{2}

Calculate the (modeled) probability P(E) using the given information, assuming that all outcomes are equally likely.
Luba_88 [7]

The probability P(E) is 13/15.

According to the statement

we have given that the S = {1, 3, 5, 7, 9}, E = {1, 5, 7}

And we have to find the probability P(E).

So, For this purpose

Recall the formula for the probability of an event E in case when all outcomes are equally likely:

P(E)= n(E) /n(S)

in which S is the sample space.

But we have the S = {1, 3, 5, 7, 9},

so, n(S) = Sum of all outcomes / number of outcomes

n(S) = 1+3+5+7+9 /5

n(S) = 25 /5

n(S) = 5 and

For n(E) = Sum of all outcomes / number of outcomes

n(E) = 1+5+7 /3

n(E) = 13 /3

n(E) = 13 /3

Substitute these values in the above written formula then

P(E)= n(E) /n(S)

P(E)=  (13/3)/ 5

P(E)= 13 /15

So, The probability P(E) is 13/15.

The quick ratio that has suddenly increased from 1.7 to 2.3 can be due to the creation of these fictitious accounts and sales.

Reika [66]

*see attachment showing the line graph

Answer:

2

Step-by-step explanation:

The red line represents the line for women, while the blue line represents the line for men.

Age 45 is the middle of 40 and 45 on the x-axis.

The average number of awakenings during the night for 45 ​-year-old men ≈ 5

The average number of awakenings during the night for 45 ​-year-old women = 3

The difference = 5 - 3 = 2 times during the night.
