Since it is a rectangular prism, the front and back are the same. the sides are the same and the top and bottom are the same. You would find the area of the front and back first. Since they both have the same measurements, you can find the area of one of the faces and multiply by 2.
A=BH
A= 3x5
A=15
15x2=30
So the front and back's area is 30. Now you find the area of both sides. They are both rectangle so the formula is A=BH.
A=BH
A=3x5
A=15
15x2=30
Now you find the area of the top and bottom. It is also a rectangle so you will use the same formula.
A=BH
A=3x3
A=9
9x2=18
Finally, you add all these measurements together adn that is the surface area.
This surface area of this rectangle prism is 78.

Answer:
$7.50
Step-by-step explanation:
you need to find out what 15% of your $50 meal cost is.This is always done by multiplying 0.15 by $50.00
14.99*.12=1.80
14.99-1.8=13.19
13.19*.0625=.94
13.19+.94=14.13
final price 14.13
Null hypothesis: There is no significant association between the existing process and the new process for reducing the population proportion of screens that will be rejected
.
Alternative hypothesis :There is a significant association between the existing process and the new process for reducing the population proportion of screens that will be rejected
.
Finally the null hypothesis will be rejected and we should accept the alternate hypothesis
Step-by-step explanation:
In the existing process the sample size and population was not known.,but the percentage of rejected screens were given as 12%.,but in the new process out of 100 screens only 6 are rejected
percentage of rejected screens using new process = 6÷ 100 ×100 = 6%
percentage of rejected screens using existing (old) process = 12%
so the new process is the effective one which reduces the rejection rate of screens., hence it is concluded that There is a significant association between the existing process and the new process for reducing the population proportion of screens that will be rejected
.
so the null hypothesis will be rejected and we should accept the alternate hypothesis
