-2 is the answer it’s very easy
Refer to the photo for my work and answer. Basically, you are finding the probability of selecting anything but an AAS student. So you add up the other students and divide by 22
We actually don't need to solve for x, just legnth
P=2(L+W)
40=P
L=x-3=L (since we are solving for Legnth not specifically x)
W=4
40=2(L+4)
divide both sides by 2
20=L+4
minus 4 both sides
16=L
legnth=16 cm (x=19 just fyi)
Answer:
x = 6
Step-by-step explanation:
You want to find factors of 78 that differ by 7. The value of x is the smaller of them.
78 = 1·78 = 2·39 = 3·26 = 6·13
We see the last factors on this list differ by 7, so we conclude x = 6.
The independent variable is the quantity of water and the dependent variable is whether or not a person catches common cold.
<h3>What is an experiment?</h3>
An experiment is the process by which we are able to establish a cause and effect relationship. An experiment must have a dependent variable and an independent variable.
The independent variable is the variable that is being changed in an experiment. As the independent variable is changed, the dependent variable also changes.
In this experiment, the independent variable is the quantity of water and the dependent variable is whether or not a person catches common cold.

Missing parts;
A researcher would like to evaluate the claim that drinking large quantities of water can help prevent the common cold. One group of participants drinks 8 glasses of water every day, and a second group drinks 2 glasses of water every day. The researcher records the number of colds each individual experiences during the 4-month winter season. . Identify the dependent variable for this study
