The amount one person will pay for a day is $4
The amount two people will pay for a day is $8
The amount Beth paid for 3 days is 4*3=12
The amount Maria paid for 3days is also 4*3=12
So to find the amount they will pay for 3days, add 12 and 12 to get 24.
The girls will pay $24 for the 3days.
Hope it helps
Answer:
C. Must be 1
Step-by-step explanation:
The correlation coefficient of an equation represents the relation between the two variable ( dependent and independent )
It lies between -1 to 1,
If an equation has strongly positive correlation then the value of correlation coefficient is 1,
If there is no relation then the value of correlation is 0,
If there is strongly negative relation then the value of correlation coefficient is -1,
Here, the equation is,
y = 2 + 3x
Since, the value of y is increasing with increasing the value of x,
We can say that there is strong positive relation between the variables x and y,
Hence, by the above statements,
The correlation coefficient between y and x in this data set must be 1.
Option 'C' is correct.
Exactly half of these integers are odd (1, 3, 5, ..., 29) so the probability of selecting an odd number is

Answer:
-68 is your answer
Step-by-step explanation:
Remember to follow PEMDAS (Parenthesis, Exponents, Multiplication, Division, Addition, Subtraction)
First, solve each parenthesis
(-21 x 3) = -63
(15/-3) = -5
Next, add
(-63) + (-5) = -63 - 5 = -68
-68 is your answer
