Answer:

The answer is C= 109.96 cm

Step-by-step explanation: Since it's a diameter, you'll have to split it in half to find the radius, from there, you can use the normal formula.

It’s C- 70 degrees
Explanation- A triangle is 180 degrees and one side is 40 degrees because you add 35 and 5 then the other two sides and is 70 so it equals back up to 180. Mark brainlist please

How do i make a equation with infinite solutions?

Igoryamba

Essentially, what you need to do is ensure that both sides cancel each other out to make 0 = 0

An example:

2(x + y) + 4 = (4x + 4y + 8)/2

2x + 2y + 4 = 2x + 2y + 4

0 = 0

There are currently 502 students at Hendrick Middle School. If that number is continuously

Alisiya [41]

Answer:

In the next 31 years

Step-by-step explanation:

In this question, we are tasked with calculating the number of years it will take for a school’s population to reach a certain amount of it is increasing at a certain rate.

We can use a mathematical exponential approach to solve this.

Let’s say;

P = I( 1 + r)^t

where P is the projected population at 926

I is the initial population at 502

r is the percentage change or rate at 2% which is same as 2/100 = 0.02

and t is time

Plugging these values, we have

926 = 502(1 + 0.02)^t

Divide through by 502

1.845 = 1.02^t

take the logarithm of both sides

log 1.845 = tlog 1.02

t = log 1.845/log 1.02

t = 30.9 = 31 years

A statistics professor gives a survey to each of the 20 students in an introductory statistics course. The survey asks the stude

tekilochka [14]

Answer:

$B2 = 0.465$ --- Population standard deviation

$C2 = 0.216$ --- Population Variance

Step-by-step explanation:

Given: Wake-up time data

Required: Determine the population standard deviation and the population variance using Excel

First, enter the given data in Excel

For this question, I entered the data in cell A2 through cell A21

Cell B2 and Cell C2 were used to hold the results of the population standard deviation and the population variance, respectively.

In cell B2, the formula to use is:

=ROUNDUP(STDEV.P(A2:A21),3)

The round function rounds the result to 3 decimal places while STDEV.P calculates the population standard deviation.

So, the result is:

$B2 = 0.465$

In cell C2, the formula to use is:

=ROUND(VAR.P(A2:A21),3)

The round function rounds the result to 3 decimal places while VAR.P calculates the population variance.

So, the result is:

$C2 = 0.216$
