Answer:
A; (4,4), (8,8) and (12,16)
Step-by-step explanation:
The value x starts with 4 and add 4 to each term
The value y start with 4 and each term next is multiplied by 2
So for x, we have;
4 , (4 + 4) and (4 + 4 + 4)
= 4,8 and 12
For y;
we have ;
4, (4 * 2) , (4 * 2 * 2)
= 4, 8, 16
so pairing up, we have;
(4,4), (8,8) and (12,16)

Answer:the answer is c
Step-by-step explanation:
There is not enough information to make a conclusion about the population mean. Then the correct option is B.
What is Mean?The mean is the straightforward meaning of the normal of a lot of numbers. In measurements, one of the markers of focal propensity is the mean. The normal is alluded to as the number-crunching mean. It's the proportion of the number of genuine perceptions to the absolute number of perceptions.
A class is gathering data on the amount of time spent watching videos each day.
Each student collected 10 pieces of data and will compile that data to determine a population mean.
One student, Megan, has a sample mean of 45.67.
The population mean can be approximated by the mean of an unlimited number of sampling means within the group according to the central limit theorem.
It is not possible to determine the population from Megan's sample mean because it only represents a small portion of the whole population.
There is not enough information to make a conclusion about the population mean.
Then the correct option is B.

The circle below has a radius of 10 inches. Find the area of Sector A and Sector C
Answer:
area of sector A = 47.97 in²
area of sector C = 109.03 in²
Step-by-step explanation:
area of full circle = πr² = (3.14)(10²) = 314 in²
area of sector A = (55/360)(314) = 47.97 in²
area of sector C = (314/2) - 47.97 = 109.03 in²
plz help me find the area of the kite
Answer:
250 cm squared
Step-by-step explanation:
The formula for an area of a kite is:
A=pq/2
--------
p = 20 and q = 25
Multiply the two together (20 × 25)
Then divide by 2 (500 ÷ 2)
Then you get your answer (250)
Whenever you find the area, be sure to add the ² symbol or squared, or else it will be wrong.

Jack bought 24 apples at the farm stand. He divided the apples between his brother, his friend, and himself in a ratio of 2:1:3. How many apples did each person receive?
Answer: 8,4, and 12
Step-by-step explanation:
Given
Jack bought 24 apples and divided them in the ratio of 2:1:3.
Suppose they get the number of apples as [tex]2x,x,3x[/tex] such that their ratio remains the same
[tex]\therefore 2x+x+3x=24\\\Rightarrow 6x=24\\\Rightarrow x=4[/tex]
So, each person gets
[tex]2x=2\times 4=8\\x=4\\3x=3\times 4=12[/tex]
Answer:
Jack's brother received 8 apples, his friend received 4 and Jack received 12 apples.

Use one of the specified points in your equation. Write your answer using integers, proper
fractions, and improper fractions. Simplify all fractions.
Answer:
y+4= 1/4 * (x+6)

Step-by-step explanation:
Point Slope formula is y-y1=m(x-x1)
All you have to do is plug those y's and x's in and you get most of your answer. The part with the actual math is that to find the m which is the slope, you have to do y2-y1/x2-x1. So 2/8 which simplified to 1/4. And BAM point Slope formula.

The crayon balloon is made up of a cone and a cylinder. What is the volume, in cubic inches, of the crayon balloon?
A) 69.12
B) 75.40
C) 138.23
D) 276.46
Answer:
A. 69.12 in.³
Step-by-step explanation:
Volume of the crayon balloon = volume of the cone + volume of the cylinder
= ⅓πr²h + πr²h
✔️Volume of Cone = ⅓πr²h
r = ½(2) = 1 in.
h = 3 in.
Volume of cone = ⅓*π*1²*3 = 3.142 in.³
✔️Volume of Cylinder = πr²h
r = ½(2) = 1 in.
h = 21 in.
Volume of Cylinder = π*1²*21 = 65.97 in.³
✅Volume of the crayon balloon = 3.14 + 65.973 = 69.115
= 69.12 in.³ (nearest hundredth)
Answer:

A circle with a radius of One-half ft is dilated by a scale factor of 8. Which statements about the new circle are true? Check all that apply. The length of the new radius will be 4 feet. The length of the new radius will be 32 feet. The new circumference will be 8 times the original circumference. The new circumference will be 64 times the original circumference. The new area will be 8 times the original area. The new area will be 64 times the original area. The new circumference will be 8 pi feet. The new area will be 16 pi square feet.change if each side is increased by a factor of 10? A rectangle with length 6 centimeters and width 3 centimeters. The perimeter will be StartFraction 1 Over 10 EndFraction the original. The perimeter will be StartFraction 1 Over 100 EndFraction the original. The perimeter will be 10 times the original. The perimeter will be 100 times the original.
Answer:
The circumference of original circle is, The area of original circle is, The dilation by scale factor 8 means the radius of new circle is 8 times of the original circle. Therefore the radius of new circle is 4 ft and the statement A is true.
y = 2.95c + 6.85 shows the cost for Mrs. Franklin to go to a buffet with c of her grandchildren. 1. What is the y-intercept and what does it mean? 2. What is the slope and what does it mean? 3. If Mrs. Franklin paid $18.65 for the buffet, how many of her grandchildren did she take with her?
Answer:
Using the form y = m x + b where b is the y-intercept and m the slop
1. 6.85 is the y-intercept- when c = 0 the value of y will be 6.85
2. the slope here is m = 2.95 that means for every increase of 1 on the x-axis which is c the value of y increases by 2.95 (additional cost of each child)
3. If no children were to go the cost would be 6.85 (c = zero)
So she paid 18.65 - 6.85 = 11.8 for the children that went
11.8 / 2.95 = 4 so 4 of her grandchildren attended

This is a pyramid problem so please help out
Answer:
Step-by-step explanation:
LA, Laterial Surface Area, is the lateral surface area of a pyramid. In this case, it is the sum of five triangles with base of 12cm and height that can be calculated as follow:
height^2 = 8.26^2 + 20^2 = 468.23
height = 21.64cm
LA = 5*1/2*12*21.64
= 649.2cm^2
SA, Surface Area, is the sum of LA and base area.
Base area = 5*1/2*12*8.26 = 247.8cm^2
SA = 649.2 + 247.8 =897cm^2
Volume, V = 1/3 * base area * height
= 1/3 * 247.8 * 20
= 1652cm^3
Answer:
Step-by-step explanation:
LA = 5x(1/2)x(12)xsqrt(8.26^2+20^2)
= 649.16
SA = LA + 5x(1/2)x12x8.26
= 896.96
V = 5x1/2x12x8.26x20/3
= 1652
