Answer: Around 100 people will answer that they prefer professional football.
Step-by-step explanation:
In the north, 70 out of 84 prefer professional football, then the relative frequency is
p = 70/84 = 0.83
Now, in the south, they asked to 120 people, and we can assume that the relative frequency will be about the same than in the north (because the relation is independent, which means that the region does not affect on the answer to the question of if they prefer professional or college football), so we have that if X people prefer professional football, we have:
p = X/120 = 0.83
X = 120*0.83 = 100
So around 100 people will answer that they prefer professional football.
Use △XYZ, in which ∠X is a right angle and tanY=815.
Answer:
8/17
Step-by-step explanation:
The correct and complete question is:
Use △XYZ, in which ∠X is a right angle and tanY=8/15. What is the ratio for sinY?
From definition:
tan(Y) = opposite/adjacent
From the graph and the question:
tan(Y) = XZ/XY = 8/15
Then:
XZ = 8 and XY = 15. Using pytaghorean theorem:
XZ² + XY² = YZ²
8² + 15² = YZ²
√289 = YZ
17 = YZ
From definition:
sin(Y) = opposite/hypotenuse
From the graph:
sin(Y) = XZ/YZ
sin(Y)= 8/17
The square based pyramid is cut horizontally at a height of 15cm to leave this frustum. Calulate the volume of the frustum.
Answer:
The answer is given below
Step-by-step explanation:
The question is not complete. The correct question is:
A square based pyramid have a height of 30 cm and base of 10 cm. The The square based pyramid is cut horizontally at a height of 15cm to leave this frustum.
Answer:
The frustum would have a base of 10 cm and height of 15 cm. The lower base has a length of 10 cm. to calculate the upper base, we use the formula:
[tex]\frac{height\ of\ frustum}{height\ of \ pyramid}=\frac{base \of\ upper\ edge}{base \of\ lower\ edge}[/tex]
Substituting:
[tex]\frac{30}{15}=\frac{10}{b} \\ b=15*10/30=5[/tex]
The volume of the frustum is given by the formula:
[tex]V=\frac{h}{3}(A_1+A_2+\sqrt{A_1A_2} )[/tex]
Where h is the height of the frustum = 15 cm, A1 is the area of the lower base = 10 * 10 = 100 cm², A1 is the area of the upper base = 5 * 5 = 25 cm²
Substituting gives:
[tex]V=\frac{h}{3}(A_1+A_2+\sqrt{A_1A_2} )=\frac{15}{3}(100+25+\sqrt{100*25} )= 875\ cm^3[/tex]

PLEASE HELP!! Solve system of equations
I think you use desmos but mine isn’t working
Answer:
The solution of system of equations is (1 , 5)
Step-by-step explanation:
The first equation is:
3y + 2x = 17
The second equation is:
-x - 4y = -12
3y + 2x = 17 :
For x = 0 , y = 5.67
For x = 1 , y = 5
For x = 2 . y = 4.33
For x = 3 , y = 3.67
For x = 4, y = 3
-x - 4y = -21 :
For x = 0 , y = 5.25
For x = 1 , y = 5
For x = 2 . y = 4.75
For x = 3 , y = 4.5
For x = 4, y = 4.25
Solve the system of Equations:
3y + 2x = 17 ⇒ a
-x - 4y = -21 ⇒ b
Multiply equation b by -1:
x + 4y = 21
Rearrange:
x = 21 - 4y
Substitute x into equation a:
3y + 2(21-4y) = 17
3y + 42 - 8y = 17
-5y = 17 - 42
-5y = -25
y = 5
Substitute y in equation b:
-x - 4(5) = -21
-x -20 = -21
-x = -21+20
-x = -1
x = 1

A telephone company charges a fixed monthly rate plus a rate per megabyte of data used. The company charges $155 for 100 megabytes and $245 for 200 megabytes. An equation can be written to show the relationship between the total megabytes of data used (x) and the total monthly charges (y). Which of the following best describes the steps to draw the graph? Draw a graph that joins the points (155, 100) and (245, 200) and has a slope = 0.9 Draw a graph that joins the points (155, 100) and (245, 200) and has a slope = 1.1 Draw a graph that joins the points (100, 155) and (200, 245) and has a slope = 1.1 Draw a graph which joins the points (100, 155) and (200, 245) and has a slope = 0.9
Answer:
Draw a graph that joins the points (100, 155) and (200, 245) and has a slope = 0.9
Step-by-step explanation:
x variable represents total megabytes of data used

Find the volume of the solid shown or described. If necessary, round to the nearest tenth. What is the volume of the shed?
Answer:
Option (B)
Step-by-step explanation:
Given shed is a composite figure having a rectangular solid at the base and a triangular prism on the top.
Volume of the shed = Volume of the rectangular prism + Volume of the triangular prism
Volume of the rectangular prism = length × width × height
= 5 × 2 × 3
= 30 m³
Volume of the triangular prism = Area of the base × height of the prism
= [tex]\frac{1}{2}(\text{Base})(\text{height of the triangular bsae})[/tex] × height of the prism
= [tex][\frac{1}{2}(5)(1.6)]\times 2[/tex]
= 8 m³
Volume of the shed = volume of the rectangular prism + volume of the triangular prism
= 30 + 8
= 38 m³
Therefore, Option (B) will be the answer.

Step-by-step explanation:
If you are given a rectangular home and a square swimming pool, with dimensions of Pool = 2x & home = (2 +5x) & (3+10x) The total amount of fencing they need can be written as x + 10. If x = 5; The family needs 5 yards of fencing for their home. The family needs 10 yards of fencing for their pool.
may I have brainliest?
The family needs 40 yards of fencing for the pool and 160 yards of fencing for the home.
PerimeterThe perimeter of a rectangle is:
Perimeter = 2(length + width)
For a square:
Perimeter = 4 * length
From the diagram:
Perimeter of pool = 4 * 2x = 8x
Perimeter of rectangle = 2(3 + 10x + 2 + 5x) = 30x + 10
Total amount of fencing = 8x + 30x + 10 = 38x + 10
x = 5. hence:
Perimeter of pool = 8(5) = 40 yards
Perimeter of home = 30(5) + 10 = 160 yard
The family needs 40 yards of fencing for the pool and 160 yards of fencing for the home.

Five-Pointed Star Logo
1. Use the interactive Spider Tool located on page 1 of this activity to recreate the
five-pointed star logo. Start by asking the spider to move 50 units, rotate 144
degrees, and repeat the sequence until she returns to her starting point. Remember
that you can use "Zoom out" or "Fit to window" if the spider leaves the viewing area.
(To draw the logo with the feet of the star on the bottom, have her rotate 72 degrees,
move 50 units, rotate 144 degrees, and then repeat the sequence until she returns to
her starting point.) In the space below, sketch the five-pointed star logo you created
with the Spider Tool. (4 points)
Answer:
see attached
Step-by-step explanation:
The image on the left in the attachment is created with an initial direction angle of 0°. The image on the right, with both feet at the bottom, is created with an initial direction of 36° (not 72°). An initial rotation of 72° results in an image like the left one, except with the origin at the bottom point.
In each case, the origin is marked with a dot.
The final result is a five-pointed start or a five-pointed start upwards if you rotate 72 degrees rather than 144 degrees the first time.
What is a star?A star is a type of polygon, which means it is a shape with multiple sides. Indeed, five-pointed stars are classified as decagons or polygons with 10 sides but the number of sides varies if the star is six-pointed, ten-pointed star, etc.
How is a five-pointed star created?All stars use lines with specific angles to be created. In the case of five-pointed stars, whcih are the most common the general pattern is:
Use lines of the same lenght and rotate 144° each time.This means that if you follow the instruction you will obtain a five-pointed star.

Answer: x = 3, y = -2 → (3, -2)
Step-by-step explanation:
Using Elimination Method, multiply the equations by a number that allows the coefficients of either x or y to be the same number with opposite signs. Then add the two equations to solve solve for the remaining variable.
I choose to eliminate x:
2x - 5y = 16 --> 3(2x - 5y = 16) --> 6x - 5y = 48
3x + 2y = 5 --> -2(3x + 2y = 5) --> -6x - 4y = -10
-19y = 38
÷19 ÷19
y = -2
Next, substitute y = -2 into either equation to solve for x.
I choose the 1st equation:
2x - 5y = 16
2x - 5(-2) = 16
2x + 10 = 16
2x = 6
x = 3
Check your answer by inputting x = 3 and y = -2 into the other (2nd) equation:
3x + 2y = 5
3(3) + 2(-2) = 5
9 + -4 = 5
5 = 5 [tex]\checkmark[/tex]
