Answer:
There is no significant difference between the means.
Step-by-step explanation:
Given is the data set for X1 and x2 are we have to do a paired t test.

(Two tailed test at 5% significance level)
Mean difference = 1.00
Std error for difference = 1.225
df=4
Test statistic = mean diff/se = 1.826
p value =0.142
Since p >0.05 our alpha we accept H0
There is no significant difference before and after averages at 5% sign. level.
Answer:
45 square centimeters
Step-by-step explanation:
The area of the triangle is given by ...
A = (1/2)bh
where b is the base, 2 cm + 3 cm = 5 cm, and h is the height, 6 cm.
A = (1/2)(5 cm)(6 cm) = 15 cm^2
__
The area of the rectangle is given by ...
A = bh
where b is the base, 12 cm, and h is the height, 2.5 cm.
A = (12 cm)(2.5 cm) = 30 cm^2
__
The area of the whole figure is the area of the triangle added to the area of the rectangle:
drawing area = 15 cm^2 + 30 cm^2 = 45 cm^2

Answer:
the annual interest rate is 7.583%
Step-by-step explanation:
We are given
Summer has an offer to buy an item with a sticker price of $13,200
so, we have
P=13200
paying $460 a month for 36 months
so, we can find total amount


Let's assume
annual interest is r
total time =36 months
so, total number of years =3
Since, it is compounded monthly
so, n=12
now, we can use formula

now, we can plug values

now, we can solve solve for r


So, the annual interest rate is 7.583%
Answer:
Question 13: For age groups y=1 and y=1.3 response is 8 microseconds.
Question 14: The club was making a loss between 11.28 and 4.88 years.
Step-by-step explanation:
Question 13:
The age group y for which the response rate R is 8 microseconds is given by the solution of the equation

We graph this equation and find the solutions to be

Since only positive solutions for y are valid in the real world we take only those.
Thus only for age groups y=1 and y=1.3 the response is 8 microseconds.
Question 14:
The footbal club is making a loss when 
Or

We graph this inequality and find the solutions to be
and 
Since in the real world only positive values for t are valid, we take the the second solution to be true.
Thus the club was making a loss in years
