Answer:
(2p + 2r) expression represents the perimeter of the rectangle.
The correct option is D )
D ) 2p + 2r
Step-by-step explanation:
Given:
Let p be the Length of Rectangle
Let r be the Width of Rectangle
To Find:
Perimeter of Rectangle = ?
Solution:
Perimeter of Rectangle:
Sum of Twice Length and Twice Width,
i.e
So we will have
(2p + 2r) expression represents the perimeter of the rectangle.
The correct option is D )
D ) 2p + 2r

Answer with explanation:</h2>
Let be the population mean.
Null hypothesis :
Alternative hypothesis :
Since the alternative hypothesis is left tailed, so the test is a left-tailed test.
Sample size : n=5 <30 , so we use t-test.
Test statistic:
Critical t-value for t=
Since, the absolute value of t (1.79) is less than the critical t-value , so we fail to reject the null hypothesis.
Hence, we have sufficient evidence to support the company's claim.
