W = 6t+90 represent the relationship between weight and number of months.
Step-by-step explanation:
Given,
Weight of wrestler = 90 kilograms
Weight after 8 months = 138 kilograms
Let,
x be the weight gained each month.
Weight of wrestler + Number of months*Weight gained each month = Weight after 8 months
Dividing both sides by 8
Therefore, the wrestler gained 6 kilograms each month.
W = weight of wrestler
t = number of months
Total weight = Weight before diet + Weight gain each month*Number of months
W = 90+6t
W = 6t+90
W = 6t+90 represent the relationship between weight and number of months.

Since the architect wants similar figures, it comes from the definition of similar triangles that the ratio of corresponding sides (all 3 sides) should be equal.
So,
.
Let's find CB.
So, CB should be 8. Option C is correct.
ANSWER: Change the length of side CB to 8 feet
Answer:
With the most common significance levels used we see that the p value is lower than the significance level so then we have enough evidence to reject the null hypothesis and we can say that the true proportion is significantly higher than 0.5
Step-by-step explanation:
Information given
n=297 represent the random sample of male taken
X=183 represent the men who said yes, they had driven a car when they probably had too much alcohol
estimated proportion of men who said yes, they had driven a car when they probably had too much alcohol
is the value that we want to test
z would represent the statistic (variable of interest)
represent the p value (variable of interest)
Hypothesis to test
We need to conduct a hypothesis in order to test the claim that the majority of men in the population (that is, more than half) would say that they had driven a car when they probably had too much alcohol, and the system of hypothesis are:
Null hypothesis:
Alternative hypothesis:
The statistic is given by:
(1)
After replace we got:
Since we have all the info requires we can replace in formula (1) like this:
Decision
We have a right tailed test so then the p value would be:
With the most common significance levels used we see that the p value is lower than the significance level so then we have enough evidence to reject the null hypothesis and we can say that the true proportion is significantly higher than 0.5
