Anew centrifugal pump is being considered for an application involving the pumping of ammonia. the specification is that the flow rate be more than 5 gallons per minute (gpm). in an initial study, eight runs were made. the average flow rate was 6.5 gpm and the standard deviation was 1.9 gpm. if the mean flow rate is found to meet the specification, the pump will be put into service. 1. state the appropriate null and alternate hypotheses

2. find the p-value

3. should the pump be put into service? explain.

14

step-by-step explanation:

14 x 3 = 42

answer: (-8,4) are the coordinates of a

step-by-step explanation:

let the side of square abcd is x .

thus the area of square abcd is .

now, by the diagram area of triangle ead= 1/2 × ea × ad = 1/2 × ea × x

( because ad is the side of square)

and, according to the question,

the areas of square abcd and right ead are equal.

⇒

⇒ea=2x

thus, ea: ab=2: 1

therefore, point a divides line segment eb into the ratio 2: 1.

⇒ by sectional formula coordinates of a are,

=

=

=(-8, 4)

thus the coordinates of a are (-8,4)

-1/3(x+1)^5

i’m pretty sure this is correct
