Answer:

A. -0.8

Step-by-step explanation:

The closer its absolute value to 1, the stronger the relationship is.

A. |-0.8| = 0.8

B. |-0.6| = 0.6

C. |-0.5| = 0.5

D. |-0.7| = 0.7

0.8 is closest to 1, therefore representing the strongest correlation.

Hope this helped :)

The zeros of a polynomial function are 1/2, -4 and -1. What are the factors?
andrew-mc [135]

Answer:

The factors are;

(x + 4) , (x + 1) and (2x-1)

Step-by-step explanation:

Given the zeros, we want to get the factors

To get the zeros, we simply equate the factors to zero and solve for x

so for x = 1/2

we can have x - 1/2 = 0

multiply through by 2

= 2x - 1

for x = -4

x + 4

for x = -1

x + 1

So the factors are;

(x + 1) , (x + 4) and (2x-1)

A commercial airline makes a flight each day from New York to Paris, France. The aircraft seats 524 passengers and serves 2 meal
nadya68 [22]
Start by multiplying the amount of passengers by 2 (for amount of meals)

524×2= 1,048

That will equal to 1,048, which is the amount of meals given out for a full plane in one day.

Now multiply that by 7 (for one week) and you'll get your answer!

524×2= 1, 028 × 7 = 7, 336 meals

7, 336 meals are given out in a one week time span on a fully packed plane.

a woman has $28,000. part is invested for one year in a certificate of deposit paying 7% interest, and the remaining amount in c
alexira [117]

Answer:

Amount invested at 7% = 16000

Amount invested at 9% = 12000

Step-by-step explanation:

Let x be the amount invested at 7% and y be the amount invested at 9%.

Since the total amount invested is $28000, therefore, we can set up the first equation as:

x+y=28000

Secondly, we are give that sum of two investments is $2200. Therefore, we can write the second equation as:

0.07x+0.09y=2200

Now we need to solve these two equations to get the values of x and y.

First of all, we multiply the second equation with 100 in order to get rid of decimal values.

(0.07x+0.09y)*100=2200*100\\7x+9y=220000

Let us use substitution method here. First of all we will solve for y from first equation and plug that into second equation.

y=28000-x

7x+9(28000-x)=220000\\7x+252000-9x=220000\\-2x=-32000\\x=16000

Therefore, amount invested at 7% is $16000 and amount invested at 9% is 28000-16000=$12000.
