If Carrie has a string 9 inches long, what she will cut the piece into  is mathematically given as

X=2.25pcs

<h3>What is the number of pieces?</h3>

Generally, the equation for the number of pieces  is mathematically given as

X=Total number *ratio

Therefore

X=9*1/4

X=2.25

In conclusion, If Carrie has a string 9 inches long, she will get 2.25 pics at a 1/4 ratio

-10=3(2m+5)+5 whats the answer
pshichka [43]

Answer:

m=5

Step-by-step explanation:

multiply 3 with the numbers in the parentheses (2m + 5) when you have 6m + 15 you will plug it into -10=6m+15+5 add your commons which will be 15 + 5 which will be 20 so the equation will be -10=6m+20, now cross your 6m with your -10 which will be -10 + 6m = 20, now cross over your -10 with 20, now your equation will be 6m=20 + 10 so now you will get 6m = 30 now divide both sides by 6 and m=5

A research company desires to know the mean consumption of meat per week among people over age 23. A sample of 164 people over a
Elan Coil [88]

Answer:

The 80% confidence interval for the mean consumption of meat among people over age 23 is between 4 and 4.2 pounds.

Step-by-step explanation:

We have that to find our \alpha level, that is the subtraction of 1 by the confidence interval divided by 2. So:

\alpha = \frac{1-0.8}{2} = 0.1

Now, we have to find z in the Ztable as such z has a pvalue of 1-\alpha.

So it is z with a pvalue of 1-0.1 = 0.9, so z = 1.28

Now, find M as such

M = z*\frac{\sigma}{\sqrt{n}}

In which \sigma is the standard deviation of the population and n is the size of the sample.

M = 1.28*\frac{0.7}{\sqrt{164}} = 0.07

The lower end of the interval is the mean subtracted by M. So it is 4.1 - 0.07 = 4.03 pounds

The upper end of the interval is the mean added to M. So it is 4.1 + 0.07 = 4.17 pounds

Rounded to one decimal place

The 80% confidence interval for the mean consumption of meat among people over age 23 is between 4 and 4.2 pounds.
