Answer:

y = 3/4x

Step-by-step explanation:

The equation of a proportional relation is ...

y = kx

The value of k can be found by dividing by x:

y/x = k

For the given values, we find k to be ...

k = y/x = (3 ft)/(4 turns) = 3/4 ft/turn

The relationship can be written ...

y = 3/4x

adelina 88 [10]

Answer:

Tuesday's Z-score is 7.56

Step-by-step explanation:

We are given that a department store, on average, has daily sales of 28,651.79 and the standard deviation of sales is $1000.

Also, it is given that on Tuesday, the store sold $36,211.08 worth of goods.

Let X = Daily sales of goods

So, X ~ N( $\mu = 28,651.79, \sigma^{2} =1000^{2}$ )

The z-score probability distribution is given by;

Z = $\frac{X-\mu}{\sigma}$ ~ standard normal N(0,1)

Now, Tuesday,s Z-score is given by;

Z = $\frac{36,211.08-28,651.79}{1000}$ = 7.56

Yes, Tuesday was an unusually good day as on this day more worth of sales takes place as compared to the average daily sales of $28,651.79 .

if you have installed 4000 linear feet of 8 inch water pipe how much will it hold when full? (answe is 10,543) i need help writi

GuDViN [60]

Answer:

$768,000\pi\ in^{3}$

Step-by-step explanation:

we know that

The volume of a cylinder (water pipe) is equal to

$V=\pi r^{2}L$

In this problem we have

$r=8/2=4\ in$ -----> the radius is half the diameter

$L=4,000\ ft$ ----> convert to inches

$L=4,000*12=48,000\ in$

$V=\pi (4^{2}48,000)=768,000\pi\ in^{3}$
