SP and Enrich are water pump manufacturers. SP claims that its water pumps have a higher maximum discharge flow rate than Enrich water pumps with the same specifications. To test the claim, a consumer bureau selected 10 water pumps from each manufacturer by visiting the distribution sites of both SP and Enrich and blindly selecting one water pump from 10 different lots at their sites. The consumer bureau found that, on average, SP water pumps had a 4% higher maximum discharge flow rate than Enrich water pumps. Given the bureau’s data collection method and report, what conclusion can be made?

A. The collection method was unfair because SP's claim may have influenced the bureau's report.
B. The collection method was random because the selection process ensured a random representation of each manufacturer's water pumps.
C. The collection method was fair because SP water pumps had the higher maximum discharge flow rate.
D. the collection method was nonrandom because only 10 water pumps from each manufacturer were selected.

Answer:

See explanation.

Step-by-step explanation:

[tex]8(k+3)=12k-4k[/tex]

Distribute the 8

[tex]8k+24=12k-4k[/tex]

Combine like-terms on right side

[tex]8k+24=8k[/tex]

This equation is not true because for any value for k, this equation will never be true. For example, if we subtract 8k from both sides, we get

[tex]24=0[/tex]

This isn’t a true statement, so your answer would be one of the following:

Step-by-step explanation:

[tex]10t^-5 = 10/t^5[/tex]

The value of  10[tex]t^{-5[/tex] in positive power is 10/ [tex]t^5[/tex].

The base number is the number that is being multiplied by itself an infinite number of times, and the exponent is the number of times that it is being multiplied. The nth power of the given number is an expression that results from multiplying a given number by itself n times.

We have,

Expression: 10[tex]t^{-5[/tex]

We know to make the power positive we have to reciprocate the number.

Now, using exponents we get

[tex]a^{-m}= 1/a^m[/tex]

So,  10[tex]t^{-5[/tex]

=  10/ [tex]t^5[/tex]

Answer:

x = 97.6

Step-by-step explanation:

cos = adjacent over hypotenuse

[tex]cos(55)=\frac{56}{x}[/tex]

* multiply each side by x *

[tex]cos(55)*x=xcos(55)\\\frac{56}{x} *x=56\\56=xcos(55)[/tex]

* divide each side by cos ( 55 ) *

[tex]\frac{xcos(55)}{cos(55)} =x\\\frac{56}{cos(55)} =97.63302055[/tex]

we're left with x = 97.63302055

Answer:

£1,725.00

Step-by-step explanation:

To calculate simple interest, we use the formula:

a = p(1 + rt)

a is the answer

p is the principle, or the starting amount of money

r is the rate, or the rate of interest (the percent)

and t is the time, or years.

First, 3% as a decimal is 0.03

So we can plug that in as r.

Then just plug the rest of the numbers in.

a = 1500(1 + 0.03 x 2)

Then just solve the equation to get 1,725.00.

Hope this helps!

Answer:

y=-5/4x-4.

Step-by-step explanation:

parallel lines have to have the same slope so they don't intersect each other

original equation with the same slope and rewrite it using point slope form:

y-y1=-5/4(x-x1) now Substitute the point(-4,1)

y-1=-5/4(x-(-4))

y-1=-5/4(x+4)

Now we can distribute the -5/4 and add 1 to the right to get our final slope-intercept form:

y-1=-5/4x-5

y=-5/4x-4.

The parallel line of y=-5/4x+7 that passes through point (-4,1) is y=-5/4x-4.

Answer: y=-5/4x-4.

The volume of the triangular prism in the diagram is:

The surface area of the triangular prism in the diagram is:

Step-by-step explanation:

First, we're gonna calculate the surface area to obtain the volume, then, to calculate the area of a triangle (because the surface o a triangular prism is just a triangle), you can use the formula:

We have this data from the diagram, where the base of the triangles is 5 inches and, the height is 4.3 inches, replacing this in the formula:

Now, we can calculate the volume of the triangular prism with the next formula:

In the diagram, we can see the depth is 14 inches, then:

How you can see with the calculations perfomed, the surface area is 10.75 [tex]in^{2}[/tex] and the volume of that triangular prism is 105.5 [tex]in^{3}[/tex].
