Answers
Answer: 75%
Step-by-step explanation:

There are 12 months. She wrote more than three articles 9 out of the 12 months. To find the percentage you need to divide. 9 divided by 12 is .75, to convert a decimal to a percent you have to move the decimal 2 places to the right. Therefore, you get 75%

Alternative hypothesis H1 : mean grade of student after using service of the tutoring company increases
H1 : μ > 0
2.)

6- A restaurant charges $48 on a food bill. The tax on the food bill is 9%.
If you give the waiter a 20% tip, what is the total cost of the bill?
Answers
Answer:
$61.92
Step-by-step explanation:
Given data
Charge for food= $48
Tax= 9%
Tip=20%
Let us find the amount of the tax and the tip
Tax
=9/100*48
=0.09*48
=$4.32
Tip
=20/100*48
=0.2*48
=$9.6
Hence the total amount paid is
=48+4.32+9.6
=$61.92

Answers
Answer:
Yes, it appears so.
Step-by-step explanation:
Based on the fact that angle L and angle P are congruent, the angles at point M are also congruent to their opposites. All of this points to triangles MNP and MLK being the same, which would mean that x does equal 15. Sorry I couldn't state any specific laws or anything.
