Answer:
64 feet × 48 feet
Step-by-step explanation:
Dimensions refers to the measurements of the house including length and breadth of the house.
Given:a blue print of a house is drawn using a scale of 
To find:the dimensions of the bedroom on the blueprint
Solution:
Length of the bedroom = 16 in
So, length of the bedroom in the blueprint = 16×4=64 feet
Breadth of the bedroom = 12 in
So, breadth of the bedroom in the blueprint = 12×4 = 48 feet
Therefore, dimensions of the bedroom in the blue print = 64 feet × 48 feet
It would be y+3. This is written as an algebraic expression.
Answer:
slope is m
y = mx + b is your standard formula
slope = -3

Hope this helps you :))
(Hope it doesn't get reported becuase it "doesn't have an explanation of how it's right") Have a blessed day ^-^
Using the t-distribution, it is found that the p-value of the test is 0.007.
At the null hypothesis, it is <u>tested if the mean lifetime is not greater than 220,000 miles</u>, that is:
At the alternative hypothesis, it is <u>tested if the mean lifetime is greater than 220,000 miles</u>, that is:
.
We have the <u>standard deviation for the sample</u>, thus, the t-distribution is used. The test statistic is given by:
The parameters are:
is the sample mean.
is the value tested at the null hypothesis.
- s is the standard deviation of the sample.
- n is the sample size.
For this problem:
Then, the value of the test statistic is:
We have a right-tailed test(test if the mean is greater than a value), with <u>t = 2.69</u> and 23 - 1 = <u>22 df.</u>
Using a t-distribution calculator, the p-value of the test is of 0.007.
