Step-by-step explanation:
1.before starting first collect the like terms.
5(2x+1)=10x
the like terms are 10x and 2x
2. 5+1=10x-2x because the 2x us crosing the equality sign
that is
6=8
The 6 measurements are 10.1, 10.02, 9.89, 10.05, 10.16, 10.21, and 10.11Mean -10.8333Sample size - 6Standard dev is 0.1Alpha is 1 – 0.90 Z (0.1) = 1.645So the computation would be:Mean ± Z* s/sqrt (n)= 10.0833 ± 1.645*0.1/sqrt(6)= 10.0833± 1.645*0.0408= 10.0833± 0.0672=10.0161, 10.1505 is the interval.90% confident that the iron rod’s true conductivity is between 10.0161 and 10.1504 microsiemens per centimeter.

:)
Answer:
Its either b or d
Step-by-step explanation:
Answer:
a. part - 14
b. total - 25
c. percent - x%
d. 100/25 = x/14; 56%
Step-by-step explanation:
What percent of 25 is 14?
a. part - 14
b. total - 25
c. percent - x%
d. The total is 100% and 25.
The part is x% and 14.
100% is to 25 as x% is to 14.
100/25 = x/14
4 = x/14
x = 56
