Carri is trying to run a certain number of miles by the end of this month. If Carrie is 55% of the way to achieving her goal and
krek1111 [17]

Answer:

20 miles

Step-by-step explanation:

Let

x = total number of miles she wish to run the end of this month

If Carrie is 55% of the way to achieving her goal and she has already run 11 miles

55% of her total miles = 11 miles

55% of x = 11 miles

55/100 * x = 11 miles

0.55x = 11

Divide both sides by 0.55

x = 11 / 0.55

= 20

x = 20 miles

x = total number of miles she wish to run the end of this month = 20 miles

She is trying to run 20 miles by the end of this month

PLEASE HELP DUE NOW!!!<br> WILL MARK BRAINLIEST!!!
Sav [38]

Answer:

(-5, -8)

Step-by-step explanation:

- 9x + 5y = 5 \\  - 5x + 5y =  - 15

- 9x + 5y = 5 \\ 5x - 5y = 15

- 4x = 20

- x = 5

x =  - 5

-5( - 5) + 5y =  - 15

25 + 5y =  - 15

5y = -40

y = -8

Anyone please...Explain &amp; solve
Nitella [24]

Answer:

y = -2x

Step-by-step explanation:

We have direct variation means

y =kx

We know y and x

10 = k (-5)

Solve for k by diving by -5

10/-5 = k (-5)/-5

-2 = k

y = -2x

A sample of 56 research cotton samples resulted in a sample average percentage elongation of 8.63 and a sample standard deviatio
ss7ja [257]

To solve for the confidence interval for the true average percentage elongation, we use the z statistic. The formula for confidence interval is given as:

Confidence interval = x ± z σ / sqrt (n)

where,

x = the sample mean = 8.63

σ = sample standard deviation = 0.79

n = number of samples = 56

 

From the standard distribution tables, the value of z at 95% confidence interval is:

z = 1.96

 

Therefore substituting the known values into the equation:

Confidence interval = 8.63 ± (1.96) (0.79) / sqrt (56)

Confidence interval = 8.63 ± 0.207

Confidence interval = 8.42, 8.84
