Answer:
For the student who is studying 10 hours a week is in the 57.93th percentile.
Step-by-step explanation:
Corresponding z-score for the student who studies 10 hours a week can be calculated by the formula
z=
where
- x is the hours student work in a week, which is 10,
- M is the mean studying hour of the class, which is 9.92,
- s is the standart deviation which is 4.54
from here we find that z=
≈0.2
Corresponding percentile for z=0.2 is 57.93
Answer:
the answer is 1.
Step-by-step explanation:
Try and plug in 1 as in x it would come out with equal to b0th sides
Answer:
f(x) = x + 9
Step-by-step explanation:
y = f(x) + C C > 0 moves it up
To shift it up 9 units
f(x) = x + 9
Answer:
4 cases were delivered each day
Step-by-step explanation:
1 case = 6 cartons
There are 8064 cartons, so we do 8064 divided by 6 to find there are1344 cases made total.
16 coffee shops means each one gets 1344/16 = 84 cases each
Deliveries were made over 21 days, so each day 84/21 = 4 cases were delivered.
This only works because the same number were produced and delivered each day.
Answer:
B.
Step-by-step explanation:
They already solved your inequality for you.
So we want to graph 
.
The line underneath the inequality tells you are going to have a closed hole at 50 (this means to include).
If there was no line underneath the inequality then you would have an open hole at 50 (this means not to include).
Now let's talk about a being less than -50 that means we shade numbers less than -50 or to the left of -50.
So the answer is B.
