We want to find the mean number of back problems for each sample, and estimate the difference. Since the groups are similar, with only the positions in which they work being different, we have matched pairs. So the correct answer is given by option c.

AlexFokin [52]

Answer:

We need to make a conversion for the new recipe. If the regular recipe calls for 2 cups of Sugar, we can make a conversion for the new recipe.

Step-by-step explanation:

Conversion- 2:7= 1:4 (sugar)

2:7 (sugar)

3: x (flour)

1: y (milk)

X= 8 (flour)

Y= 6 (milk)

3.5 cups of milk

10.5 cups of flour

7 cups Sugar

What value of x gives y=-2? plz help !

Ivanshal [37]

Answer:

-1

Step-by-step explanation:

to find x, use the following formula:

y = mx + b

(y = 0)

(m = change in y-value ... which is 2)

(x = change in x-value ... which is 2)

(b = y-axis ... which is -2)

y = mx + b

y = $\frac{2}{2}$ + -2

$\frac{2}{2}$ = 1

y = 1 + -2

y = -1

The amount of money you have is $ 20864.521

<h3>Solution:</h3>

Given that you invested $15,000 dollars for 11 years at 3% annual interest compounded continuously.

To find: total amount of money

The compound interest formula for compounded continously is given as:

$A = p e^{rt}$

Where "p" is the principal

"r" is the rate of interest

"t" is the number of years

Here in this problem, p = 15000

t = 11 years

$r = 3 \% = \frac{3}{100} = 0.03$

Substituting the values in formula we get,

$A = 15000e^{0.03 \times 11}\\\\A = 15000e^{0.33}\\\\A = 15000 \times 1.390968\\\\A = 20864.521$

Thus the amount of money you have is $ 20864.521
