Answer:
Tuesday : Total = 30 : 72 = 5 : 12
Step-by-step explanation:
Monday: 42 miles
Tuesday: 42 - 12 = 30 miles
Monday + Tuesday: 42 + 30 = 72 miles
Tuesday : Total = 30 : 72 = 5 : 12
Answer:
P(x) = 0.50x - 5
Step-by-step explanation:
x = number of glasses sold
She charges $0.50 per glass, so her revenue is
R(x) = 0.50x
which is the amount of money she brings in
Her cost function is
C(x) = 5
assuming she only spends that $5.00 on the supplies mentioned.
The profit P(x) is the difference of revenue and cost
Profit = Revenue - Cost
P(x) = R(x) - C(x)
P(x) = 0.50x - 5
Part A:
For this case we have that the relationship between time and radius is linear.
We observe that for each day that passes, the radius increases two centimeters.
Therefore, the linear function is:
y = 2x
Since the linear function is exact, the correlation coefficient is:
r = 1
Answer:
r = 1
Part B:
As the linear function is:
y = 2x
So for days 1 and 2 the slope of the graph is:
m = 2
It means that the radius increases 2 centimeters per day.
Answer:
m = 2
Part C:
The data represents a correlation.
This is because the data follows a linear trend.
The radius always grows 2 centimeters for each day that passes.
Answer:
Correlation.
Answer:
Step-by-step explanation:
You first want to get rid of the numbers which are in parenthesis
(-345(-23)
This is a multiplication between negative numbers
The law of signs in mathematics states that negative times negative equals positive
(-) (-) = +
(-345(-23)= 7935
Then we multiply the number which is outside of the parenthesis (4x)
(4x)7935= 31740x
$820.
If you divide 656 by 8 (since it's 80% of the total price), you get 82.
Multiplying 82 by 10 would equal the original price.
