Answer:
The correlation coefficient is determined by dividing the covariance by the product of the two variables' standard deviations. Standard deviation is a measure of the dispersion of data from its average. Covariance is a measure of how two variables change together.

he recipe makes enough stew for 6 people, and the ingredients cost $9.75. How much would it cost to serve 24 people?
A student solved the problem using the proportion StartFraction 6 over 9.75 EndFraction = StartFraction c over 24 EndFraction Explain the error in this proportion.
Answer:
24 times 9.75 = $234
Step-by-step explanation:
Answer:
It would cost $39 to serve 24 people
Step-by-step explanation:
If the recipe makes enough stew for 6 people, and the ingredients cost $9.75, then for 24 people it will cost $x. You can write this statement as
6 people - $9.75,
24 people - $x.
Or as proportion,
6/24=9.75/x
Find x:
6·× =9.75·24,
x=9.75·24/6=9.75·4=39
Answer: It would cost $39 to serve 24 people

If each block sides are 1 cm long, what is the volume of this object?
4 cubic centimeters.
Brainliest would be great. Comment below if it helped!
Answer:
The volume for this object is 4.
Step-by-step explanation:
For each block, we need to multiply using the volume formula which is
Length x Width x Height
So, if the side lengths for all these blocks are 1. That means we would do 1x1x1 for every block. Since there are 4 blocks that means our equation for the whole object would be 1+1+1+1 or simply 1x4. And we all know the answer to our equation 1 x 4 is 4.
, Hope this helps :)
Have a great day!!
Which graph represents the solution set of the system of inequalities?
Answer:i think is A
Step-by-step explanation:
helpppppppppppppppppppppppppppppp meeeeeeeeeeeeeeeeeee plsssssssssssssssssssssss there is more but plss help mee
Answer:
x + y =5 .......eqn (1)
x - y =3 .......eqn(2)
using substitution method
x + y = 5
-
x - y = 3
0 + 2y=2
y = 2/2
y = 1
substitute y in egn(1)
x + 1 = 5
x = 5-1
x = 4
then (x, y) = (4,1)
A pitcher contains 4.5 pints of iced tea. How many fluid ounces of iced tea are in the pitcher?
Peyton has two summer jobs. During the week she works in the grocery store, and on the weekend she works at a nursery. She gets paid $15 per hour to work at the grocery store and $16 per hour to work at the nursery. How many total hours does she work if she does 12 hours at the grocery store and 9 hours at the nursery? How many total hours does she work if she does gg hours at the grocery store and nn hours at the nursery?
Answer:
Total hours worked = 21
Total earned = 15gg + 16nn
Step-by-step explanation:
We know:
Grocery store: $15/hour
Nursery: $16/hour
Total hours worked = 12 + 9 = 21
Your expression would be:
Total earned = 15gg + 16nn
Can anyone answer with an explanation?
Answer:
x=0.136

simplify −4x² y+5x+5−3x+4x² y−8
Answer
2x-3
Step-by-step explanation:
given:
−4x² y+5x+5−3x+4x² y−8
=−4x² y+4x² y+5x-3x+5-8
=2x-3
hope it helps!!
Let's simplify step-by-step.
(−4x2)(y)+5x+5−3x+4x2y−8
=−4x2y+5x+5+−3x+4x2y+−8
Combine Like Terms:
=−4x2y+5x+5+−3x+4x2y+−8
=(−4x2y+4x2y)+(5x+−3x)+(5+−8)
=2x+−3
=2x-3
Therefore the answer is 2x-350 = -1/3b + 20

Select all the statements that best describe the graph below.
The Correct choices are :
The independent variable is MonthsThis is a positive relationship The relationship is linear The rate of change is constant The dependent variable is dollars in savings accountRobin works as a customer service representative. She knows that the
amount in dollars of her yearly bonus is represented by the expression - 1.25x + 651, where x is the
number of complaints customers had about her during the year. To find her bonus if she gets 12
complaints, she substitutes 12 for x. What should be her next step? What would her bonus be?
Answer:
multiply -1.25 x 12
Sense a negative and a positive will always be negative when dealing with multiplication you'll get -15
now -15 +651= 636
always take the sign of the biggest number.

Explain or show work to prove that the following equation is true.6 x 8 = 3 x 2 x 2 x 2 x 2
Answer:
see explanation
Step-by-step explanation:
To prove the equation id true, solve both sides and if they are equal then the equation is true.
left side = 6 × 8 = 48
right side = 3 × 2 × 2 × 2 × 2
= 6 × 2 × 2 × 2
= 12 × 2 × 2
= 24 × 2
= = 48
Since both sides are equal then the equation is true

Answer this for 50 points
Answer:
This would be point M.
Step-by-step explanation:
Hope this helps!
Answer:
M
Step-by-step explanation:
(3.75, -2.25)
The first coordinate is the x coordinate which means left or right.
Since it is positive we go to the right 3.75 units
The second coordinate is the y coordinate which means up or down
Since it is negative we go down 2,25 units
The point is labeled M

Consider the line with equation y=-2x + 2.
Can you write the equation of a line through
point (3,-4) that is perpendicular to the given line?
Answer:
[tex]m_{1} \times \frac{1}{m_{2}} = - 1 \\ m_{2} = \frac{1}{2} \\ \frac{1}{2} = \frac{y + 4}{x - 3} \\ 2y + 8 = x - 3 \\ 2y = x - 3 - 8 \\ 2y = x - 11 \\ y = \frac{1}{2} x - \frac{11}{2} [/tex]
