Last year Jo paid £245 for her car insurance. This year she has to pay £883 for her car insurance. Work out the percentage incre

S_A_V [24]

Answer:

260%

Step-by-step explanation:

To solve how much the percentage increase cost of Jo's car insurance is, we first need to list down our variables.

1st year = £245

2nd year = £883

First off, we need to find the difference of the two.

Increase = £883 - £245

Increase = £638

Now to find the percentage increase, we take our increase and divide it by our 1st year's payment and multiply it by 100.

Percentage increase = $\dfrac{638}{245}*100$

Percentage increase = $2.60*100$

Percentage increase = 260%

So the percentage increase of last years payment to this years payment is 260%.

The answer to your question is seen below.

To avoid paying the retroactive APR of 21% he will pay if cannot pay on time, Jerry’s last month payment must be $ 1,425.

Hope my answer would be a great help for you.

Find an equation of the line that has a slope of 3 and a y intercept of -4. Write your answer in the form

allsm [11]

Step-by-step explanation:

When using the slope-intercept form equation, we can determine that;

m represents the slope.
b represents the y-intercept.

Since the slope and y-intercept are given, substitute the values into the equation.

Substitute:

$y = 3x - 4$

A manufacturing company employs two devices to inspect output for quality control purposes. The first device is able to accurate

Feliz [49]

Answer:

(a) fxy(x,y) = f(x), f(y)

(b) fx(x) = X = (99.3/100) x 4 = 3.972

(c) E(X) = 4

(d) fy/2y = (99.7/100) of (2 x 4) = 7.976

(e) E(Y | X = 2) = 2.

(f) V(Y | X = 2) = 2

Step-by-step explanation:

fxy(x,y) = f(x), f(y), as the question presented the assumption that the devices are independent, their measurements must also be independent

Since the first device is able to accurately detect 99.3% of the defective items it receives and the total defective items sent is 4,

(b) fx(x) = X = (99.3/100) x 4 = 3.972

(c) E(X) is expected result from first device. It is 4 because the items will be whole number.

(d) fy/2y = (99.7/100) of (2 x 4) = 7.976

(Since the first device is able to accurately detect 99.7% of the defective items it receives and the total defective items sent is 4)

(e) E(Y | X = 2) = 2. If the second device measure 2 defective items (X = 2), first device will also detect 2 because the measure 99.3% and 99.7% accurately. Their measurements will be approximately equal.

f. V(Y | X = 2). Like the explanation for (e) above, any relations V(Y | X = 2) will also be 2

(g) X and Y are independent because the are measure

measurements on two different devices
