2 is the coefficient in the given expression.
<u>Step-by-step explanation:</u>
- The coefficient is said to be the numerical value which is multiplied with the variable. (i.e) the number which is in product with the variables in an equation or expression is said to be the coefficient .
- Here in the given following equation -5+2v : 2 is said to be in multiple with the v where v is said to be variable.
- Thus 2 is said to be the coefficient in the given expression.

Answer:
415.48 or 132.25 pi cm
Step-by-step explanation:
23 divided by 2 is 11.5 so that is the radius. Then you multiply the radius by pi. Or you can do 11.5 x 11.5 if you are trying to find the solution without pi.
Answer:
Step-by-step explanation:
We would set up the hypothesis test. This is a test of a single population mean since we are dealing with mean
For the null hypothesis,
µ = 6.8 psi
For the alternative hypothesis,
µ ≠ 6.8
This is a 2 tailed test
Since the population standard deviation is given, z score would be determined from the normal distribution table. The formula is
z = (x - µ)/(σ/√n)
Where
x = sample mean
µ = population mean
σ = population standard deviation
n = number of samples
From the information given,
µ = 6.8
x = 6.9
σ = 0.7
n = 140
z = (6.9 - 6.8)/(0.7/√140) = 0.17
Therefore, the value of the test statistic us 0.17
