Answer:
He isn't correct. He spent 25% more time this week than the previous one.
Step-by-step explanation:
We will make proportion.
first week 20 hours is 100%
second week 25 hours is x%
20 : 25 = 100 : x
When we multiply external and internal members we get:
20x =25 · 100 => x = 2500/20 = 125%
We conclude the following:
Evan spent 125% of the time in hours compared to the last week or Evan spent 25% more time this week than the previous one.
God with you!!!
Sample response: The work shown is not correct. When the distributive property was used, the -10i should have changed to +10i, making the sum 8+12i.
Answer:
D) We are 95 percent confident that the mean difference in scores for all children in the program is between 20.1 points and 23.9 points.
Step-by-step explanation:
x% confidence interval:
A confidence interval is built from a sample, has bounds a and b, and has a confidence level of x%. It means that we are x% confident that the population mean is between a and b.
95 percent confidence interval (20.1,23.9)
We are 95% sure that the population mean(that is, the mean for all children in the program) is in this interval. So the correct answer is given by option D.

1)
n=side number
a=exterior angle
n.a=360
n.30=360
n=12
2)
3x+10+x+148+117+90=450
4x=85
x=21.25
3)
n.a=360
30.a=360
a=12 exterior angle
180-12=168 interior angle
