Answer:
27.72 inches of fabric
Step-by-step explanation:
28+3=31
<h3>Fabric used on
each player:</h3>
559.24÷31=<u>18.04</u>
271.04÷28=<u>9.68</u>
18.04+9.68=<u>27.72</u>
Answer:
test statistic = 12.115
Step-by-step explanation:
Given data :
std = 2.1 years
n = 10
( std )^2 = 4.41
<u>determine the test statistic</u>
apply a two-tailed test ( chi squared test for one population variance )
test statistic
λ^2 = 
( Referring to Exhibit 11-1 )
= ( 10 - 1 )*(2.1)^2 / 3.2761
= 12.115
Answer:
B.35
Step-by-step explanation:
The sequence is
14, ,56,....
14 , x , 56
Think of it as 14 + d = x
x+ d = 56
d is the common difference
We now have 2 equations and 2 unknowns
Substitute the first equation in for x into the second equation
x+d =56
(14+d) +d = 56
Combine like terms
14 + 2d = 56
Subtract 14 from each side
14-14 + 2d = 56-14
2d = 42
Divide by 2
2d/2 =42/2
d = 21
The common difference is 21
Now we can find x
14 + d = x
14+ 21 = x
35 =x
The unknown term is 35
