Answer 1

Answer:

Step-by-step explanation:

This is a geometric sequence or if you prefer exponential decay of the form

y=ar^t where a is the initial value (at x=0) and r is the common ratio or rate, in this case

dividing any term by the previous term is a constant r=1/4, that is our rate or common ratio so

y=40(1/4)^x

The 2 is an exponent or a thing above a number

Answers

I’m guessing you have to use pemdas
1. You have to do exponents which is 4^2 and it gives you 16
2. You have to do parenthesis
(5+16) divide 3 • 6
21/3•6
3. Then you do division
21/3 = 7
4. Last you multiply 7 • 6
So the answer is 42

B. 12m + 4 = 20
C. 12m – 4 = 20
D. 4 = 20 – 12m
E. 20 + 12m = 4

Answers

the answer will be E because the only one that answers what you’re talking about is E the rest do not make sense

The equation that represents the total number of students in Bryan's

homeroom is m + 8 = 40.

What is an equation?

An equation is written in the form of variables and constants separated by the operation of multiplication and division,

An equation states that terms in different forms on both sides of the equality sign are equal.

Multiplication and division do not separate the terms of an equation.

Let, 'm' be the number of students in Bryan's homeroom.

Given, Four more than half of the students in Bryan’s homeroom have tickets to attend the school’s musical which is 20.

Therefore, The equation to find the number of students in Bryan's homeroom is, (1/2)m + 4 = 20.

m + 8 = 40.

Whish strategy is correct for solving 563 - 299?

A. subtract 63 from 563 to get to 500. Then subtract 200 to get to 300 and subtract 1 more to get 299. So, 63 + 200 + 1 = 264

B. Add 1 to 299 to get 300. Then add 100 to 300 to get 500. Then add 63 to 500 to get 563. So, 1 + 100 + 63 = 164.

C. Subtract 3 from 563 to get 560. Then subtract 200 from 560 to get 360. Then subtract 60 to get 300, So, 3 + 200 + 60 = 263

D. Add 200 to 300 to get 500. Then add 63 to get 500 to get 563. So, 200 + 63 = 263 (IM GIVEING 100 points TO WHO EVER GETS THIS CORRECT)

a sample of
45 women
a sample of
60 women

Answers

60 women, 45 women, 20 women, 5women ,

Answer:   The answer is 60, 45, 20, then 5.

Step-by-step explanation:

The variance would increase the bigger the numberr because there is more data. Lets says that the 5 women have a range of 1 and 10 with a meam with a 5. The data separating the mean and the top range is 5. But lets says that the range for the women is 1 and 80, with a mean of 40. The difference in the mean and the top range is 40. 40>5 because there is simply more data. Therefore higher variance.
