Answer:
-10,1,19
Step-by-step explanation:
x+y+z = 10 (Equation 1)
2y-x= 12 (Equation 2)
x-y+2z = 7 (Equation 3)
(Equation 2): -x = -2y+12
x = 2y-12 (Equation 4)
(Equation 1) - (Equation 3): 2y-z = 3
-z = -2y+3
z = 2y-3 (Equation 5)
Substitute (4) and (5) into (1)
x+y+z = 10
(2y-12)+y+(2y-3) = 10
5y-15 = 10
5y = 5
y=1
Substitute y=1 into (2)
2y-x= 12
2(1)-x= 12
2-x= 12
-x= 12-2
-x= 10
x= -10
Substitute y=1 and x=-10 into (1)
x+y+z = 10
-10+1+z = 10
z-9 = 10
z = 10+9
z = 19
Order: x = -10, y = 1, and z = 19

If you save $3,000 at an interest rate of 14 percent per year, how much will you have at the end of six years? The interest should be compounded. A. $5,805.96 B. $6,502.34 C. $6,584.91
Answer:
C.) $6,584.91
Step-by-step explanation:
Amount earned in compound interest = P(1 + r)^n;
where P is the principal,
r is the rate and n is the number of periods.
Amount = 3,000(1 + 14%)^6 = 3,000(1 + 0.14)^6 = 3,000(1.14)^6 = $6,584.91
Answer:
C) 6584.91

Find the surface area of a cube is 150 cm2. What is the length an edge of
the cube? (all of the sides are squares)
Answer:
5
Step-by-step explanation:
The formula is 6x^2
If you set it equal to 150
Answer:
5 x 5 + 5 x 5 + 5 x 5 + 5 x 5 + 5 x 5 + 5 x 5 = 25 + 25 + 25 + 25 + 25 + 25 = 50 + 50 + 50 = 150
5 would be the missing side because it fits the formula
(A x A) + (A x A) + (A x A) + (A x A) + (A x A) + (A x A) = Surface area

Provide the intervals and frequencies you would use to construct the histogram for this data set.
Answer:
39
Step-by-step explanation:
To find the intervals you will need to find the lowest and highest numbers, in this case, it would be 1 and 35. A general rule would be 5-7 intervals, I will use 5.
Here are the intervals with the number of people that were in each:
1-7 (9)
8-14 (14)
15-21 (8)
22-28 (3)
29-35 (5)

James is putting 24 jelly beans into equal rows. He says there will be more jelly beans in 2 equal rows
than in 3 equal rows. Is James correct? Explain.
Select the correct answer below, and fill in the answer box(es) to complete your choice.
(Type a whole number.)
OA. Yes. James is correct. There are fewer rows, so there will be more in each row. There will be
jelly beans in each row for 2 equal rows, and jelly beans in each row for 3 equal rows.
OB. No. James is not correct. There are fewer rows, so there will be fewer in each row. There will be
jelly beans in each row for 2 equal rows, and jelly beans in each row for 3 equal rows.
OC. No. James is not correct. It doesn't matter how many rows there are. There will always be
jelly beans in each row.

Answer:
(A)James is correct.There are fewer rows, so there will be more in each row. There will be 12 jelly beans in each row for 2 equal rows, and 8 jelly beans in each row for 3 equal rows.
Step-by-step explanation:
James is putting 24 jelly beans into equal rows.
If he puts the jelly beans in 2 equal rows:
Number in each row=24/2=12 jelly beans per row.
If he puts the jelly beans in 3 equal rows:
Number in each row=24/3=8 jelly beans per row.
Therefore, James is correct.There are fewer rows, so there will be more in each row. There will be 12 jelly beans in each row for 2 equal rows, and 8 jelly beans in each row for 3 equal rows.
The correct option is A.

What are the slope and the y-intercept of the linear function that is represented by the graph?
On a coordinate plane, a line goes through points (negative 3, 0) and (negative 2, 4).
The slope is 3, and the y-intercept is 9.
The slope is 3, and the y-intercept is 12.
The slope is 4, and the y-intercept is 9.
The slope is 4, and the y-intercept is 12.
Answer:
The slope is 4, and the y-intercept is 12.
Step-by-step explanation:
In the given question, the line goes through points (-3,0) and (-2,4).
We need to find the slope and the y-intercept of the line.
Finding Slope:Slope is [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex].
With points (-3,0) and (-2,4):
[tex]m=\frac{4-0}{-2-(-3)}=\frac{4}{1}=4[/tex]
The slope of the line is 4.
Finding y-intercept:An appropriate equation for what we have so far is:
[tex]y=4x+b[/tex]
We can solve for 'b' to get the y-intercept.
Replace 'x' and 'y' with one of the coordinates and solve for 'b':
[tex]4=4(-2)+b\\4*-2=-8 \leftarrow \text {Distribute}\\4=-8+b\\4+8=-8+8+b \leftarrow \text {Addition Property of Equality} \\\boxed {12=b}[/tex]
The y-intercept is 12.
Final Answer:The answer should be: "The slope is 4, and the y-intercept is 12."
Answer:
The answer is d, which is the slope of 4 and the y- intercept is 12.

It can't be A or B because those are positive. D is strongest because it is clusters closest together and there is a more definitive line.

What is the distance from A to A'?

2/5
Answer: Choice D) [tex]2\sqrt{5}[/tex]
===========================================================
Work Shown:
Point A starts at (-2,3) and moves to (2,5) after applying the translation rule of "shift 4 to the right, 2 up".
Use the distance formula to find the distance from (-2,3) to (2,5)
[tex]d = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}\\\\d = \sqrt{(-2-2)^2 + (3-5)^2}\\\\d = \sqrt{(-4)^2 + (-2)^2}\\\\d = \sqrt{16 + 4}\\\\d = \sqrt{20}\\\\d = \sqrt{4*5}\\\\d = \sqrt{4}*\sqrt{5}\\\\d = 2\sqrt{5}\\\\d \approx 4.472136\\\\[/tex]

A biased coin is tossed 40 times. Out of those 40 tosses, the coin landed on heads 12 times.
Find the probability of the coin landing on tails.
Answer:
Step-by-step explanation:The probability of picking the biased coin: P(biased coin)=1/100. The probability of all three tosses is heads: P(three heads)=1×1+99×18100. The probability of three heads given the biased coin is trivial: P(three heads|biased coin)=1.

A company is trying to calculate the amount of
concrete that will be needed to create one concrete
block that is in the form below.
The concrete block is a rectangular prism with two
cubes cut out. The cubes have a side length of 6
inches.
What is the total volume, cubic feet, of concrete
needed to make this block?
Answer:
[tex]0.19\,\,cubic\,\,feet[/tex]
Step-by-step explanation:
Given:
The concrete block is a rectangular prism with two cubes cut out. The cubes have a side length of 6 inches.
To find: total volume, cubic feet, of concrete needed to make this block
Solution:
Side of cube = 6 inches
Volume of cube = [tex](side)^3=6^3=216\,\,cubic\,\,inches[/tex]
So, volume of two cubes = 2(216) = 432 cubic inches
Length of rectangular prism = 12 inches
Breadth of rectangular prism = 8 inches
Height of rectangular prism = 8 inches
Volume of rectangular prism = length × breadth × height = [tex]12(8)(8)=768 \,\,cubic\,\, inches[/tex]
Total volume of concrete needed to make this block = Volume of rectangular prism - Volume of two cubes = 768 - 432 = 336 cubic inches = [tex]\frac{336}{1728} =0.19\,\,cubic\,\,feet[/tex]
( use 1 cubic inch = [tex]\frac{1}{1728} \,\,feet[/tex])

Which of the following equations represents the line graphed below?
Answer:
y= -2x +3
Step-by-step explanation:
This is because the slope is 2 using rise over run and the y-intercept is 3 because it meets at that point, (0,3) on the number line.
Answer:
y= -2x +3
Step-by-step explanation:
How? We have to take a good look at the line graph
So we know that Y is equals to 2x +3 (first option)
