adell [148]
Campers = y and counselors = x.....1 counselor to 5 campers

y = kx
k = y/x
k = 5/1

y = 5x

lets check..
y = 5x....lets say u have 2 counselors...sub in 2 for x
y = 5(2)
y = 10....so when there is 2 counselors, there are 10 campers

y = 5x...lets say u have 3 counselors...sub in 3 for x
y = 5(3)
y = 15...so when there are 3 counselors, there are 15 campers

2/10 reduces to 1/5
3/15 reduces to 1/5

so yes, this is a direct variation with ur equation being y = 5x

PLEASE HELP ME! THE QUESTION IS DOWN BELOW PLEASE PLEASE HELP ME
Basile [38]

The given expression (8h + 2w - 5h + 3w) can fully be simplified as 3h + 5w.

<h3>What is an expression?</h3>

An expression can be defined as a type of mathematical equation which is used to show the relationship that is existing between two or more variables and numerical quantities (integers).

In this exercise, you're required to fully simplify the given expression in the lowest terms. Thus, we would simplify the given expression completely by collecting like terms and performing the necessary arithmetic operations (addition and subtraction) as follows:

Collecting like terms, we have:

8h - 5h + 3w + 2w

Subtracting and adding the like terms respectively, we have:

3h + 5w.

In conclusion, we can logically deduce that the given expression (8h + 2w - 5h + 3w) can fully be simplified as 3h + 5w.

Which of the following situations provides the strongest evidence that a coin is NOT fair?
Kamila [148]

Answer:

D

Step-by-step explanation:

A coin has two sides. A side tagged the head and the order side tagged the tail.

By mathematical and probabilistic standards, a fair coin is a coin which has equal value of probabilities for head turning up as well as tail turning up.

what we are saying here is that for a fair coin, P(H) = P(T) = 0.5 or 1/2

Any option or value short of this will make the coin unfair. Whenever we are having the probability of the head greater than the probability of the tail or vice versa, then the coin in question has become unfair.

Now back to the options, by observation, expressing each of the options to the smallest numbers will yield 7/10.

Let’s have a decimal value of each go drive home the point;

7/10 = 0.7

70/100 = 0.7

700/1000 = 0.7

Thus the probability of the head which is meant to be 0.5 is now given as 0.7 which shows that the coin is unfair in all three options since in the real sense they are all same numbers written in different form which of course is not the 0.5 value we should have for a fair coin for probability of getting a head
