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?
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

Your friend says that enough information is given to prove that x= 15. Is your friend correct?
please help
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.
Multiple Choice
Use the diagram below to answer questions 1–3.
Which angle is congruent to angle 1?
A. angle2
B. angle5
C. angle6

identify hypotheses.Write the null and alternative hypotheses in words and then symbols foreach of the following situations.(a) A tutoring company would like to understand if most students tend to improve their grades(or not) after they use their services. They sample 200 of the students who used their servicein the past year and ask them if their grades have improved or declined from the previousyear.(b) Employers at a firm are worried about the effect of March Madness, a basketball championship held each spring in the US, on employee productivity. They estimate that on a regular businessday employees spend on average 15 minutes of company time checking personal email, makingpersonal phone calls, etc. They also collect data on how much company time employees spendon such non-business activities during March Madness. They want to determine if these dataprovide convincing evidence that employee productivity changed during March Madness.(c) Since 2008, chain restaurants in California have been required to display calorie counts ofeach menu item. Prior to menus displaying calorie counts, the average calorie intake of dinersat a restaurant was 1100 calories. After calorie counts started to be displayed on menus,a nutritionist collected data on the number of calories consumed at this restaurant from arandom sample of diners. Do these data provide convincing evidence of a difference in theaverage calorie intake of a diners at this restaurant
Answer:
H0 : μ = 0 ; H1 : μ > 0 ;
H0 : μ = 15 ; H1 : μ ≠ 15
H0 : μ = 1100 ; H1 : μ ≠ 1100
Step-by-step explanation:
Null hypothesis H0 : mean grade of student after they use service of tutoring company is the same.
H0 : μ = 0
Alternative hypothesis H1 : mean grade of student after using service of the tutoring company increases
H1 : μ > 0
2.)
Null hypothesis H0 : Average or mean company time spent checking personal is 15 minutes
H0 : μ = 15
Alternative hypothesis H1 : Average or mean company time spent checking personal mail is not equal to 15 minutes
H1 : μ ≠ 15
C.)
Null hypothesis H0 : Average calorie intake of diner at restaurant.
H0 : μ = 1100
Alternative hypothesis H1 : There is a difference in average calorie intake of diner at restaurant.
H1 : μ ≠ 1100
