Answer:
D. 
Step-by-step explanation:
We have been given that Mikayla is a waitress who makes a guaranteed $50 per day.
Since Miklaya works 6 days per week, so the guaranteed income for one week would be
We are also told that she gets tips of 20% of all her weekly customer receipts, t. So amount earned from tips would be 20% of t, that is
.
Total amount earned in one week would be guaranteed income for 1 week plus 20% of t:

Therefore, our required function is
and option D is the correct choice.
Answer:
66 minutes, or 1 hour and 6 minutes.
Step-by-step explanation:
let us first do the rectangular aquarium:
8 x 10 = 80
80 x 14 = 1120
now the second box
23 x 25 = 575
575 x 33 = 18975
we can divide the boxes volume:
18975/575 = 33
so all we have to do is times 33 by 2 which equals:
66 minutes, or 1 hour and 6 minutes.
Answer:
150 students
Step-by-step explanation:
According to statement we have the following information
number of juniors=n=300
mean score=24
standard deviation score=4
The number of students that score above 24 is determined by
Number of students score above 24=number of juniors* P(student score above 24)
P(student score above 24)=P(x>24)=P(x-mean/sd>24-24/4)=P(z>0)=0.5.
Students score above 24=np=300*0.5=150
Hence there are 150 students scored above 24.
-4x-2+4
or -4x+4-2
Without variable they can go in any order.
