Answer:
D. 1 1/2 feet
Step-by-step explanation:
<u>Multiply the numbers to find the length of wire used.</u>
- 2 1/2 × 3/5 =
- 5/2 × 3/5 =
- 3/2 =
- 1 1/2 feet
Correct choice is D
Let’s divide 48 by 16 to see how many cents per inch of wire. 48/16=3 so it costs 3 cents per inch of wire. now all we have to do is multiply 47 by 3, and you will get 141 cents, or $1.41.

Answer:
0.1338 to the nearest ten thousandth.
Step-by-step explanation:
40 / 299
= 0.1337792642
we have the data set
3,1,7,0,4
step 1
Find out the sample mean
sample mean=(3+1+7+0+4)/5
sample mean=15/5
sa,ple mean=3
step 2
Complete the table
x (x-mean) (x-mean)^2 x^2
3 (3-3) (3-3)^2 0
1 (1-3) (1-3)^2 4
7 (7-3) (7-3)^2 16
0 (0-3) (0-3)^2 9
4 (4-3) (4-3)^2 1

15 30
Find out the standard deviation of the sample
SD=√(30/n-1)
SD=√(30/5-1)
SD=2.74
