Answer:
y = 10
Step-by-step explanation:
Given y varies inversely as x then the equation relating them is
y = [tex]\frac{k}{x}[/tex] ← k is the constant of variation
To find k use the condition x = 4 when y = 15 , then
15 = [tex]\frac{k}{4}[/tex] ( multiply both sides by 4 )
60 = k
y = [tex]\frac{60}{x}[/tex] ← equation of variation
When x = 6 , then
y = [tex]\frac{60}{6}[/tex] = 10

answer 4
explanation
Nikki sold 4 more than Samantha number times 5
24-4=20
so Samantha number times five equals 20
20÷5=4

A pyramid and a cone are both 8 centimeters tall and have the same volume.
What statement must be true about the two solids?
АА
A. The area of the cross-sections of the prisms are multiples of each
other
B. The cross-sections of the prisms are the same shape.
C. The vertical cross-sections of the prisms at the same width must
have the same area.
D. The horizontal cross-sections of the prisms at the same height
must have the same area.
SUBMIT
Answer:
D
Step-by-step explanation:
The horizontal cross-sections of the prisms which is at same height as the cone should have same area.
Therefore Option D is the answer.
What is a Cone ?A cone is a three dimensional figure that has a circular horizontal structure , and vertically tapering up till a point.
It is given that
A Pyramid and a cone both have same volume.
Height of cone is same as Height of Pyramid .
Volume of cone = (1/3)πr²h
Volume of a pyramid = Area of base * h
When both the volume are equated
as height is same
The Area of the base of the cone = Area of the base of the Pyramid
The horizontal cross-sections of the pyramid which is at same height as the cone should have same area.
Therefore Option D is the answer.

Answer's too short so here's some extra text.
The equation of the line that goes through the points ( − 3 , − 9 ) and ( − 6 , − 3 ) can be written in the form y = m x + b
Answer:
[tex]y=-2x-15[/tex]
Step-by-step explanation:
[tex]y=mx+b[/tex].
m is the slope of the line. To find it we can do [tex]\frac{dy}{dx}[/tex] which is the difference between the y-coordinates divided by the difference between the x-coordinates.
So: [tex]\frac{dy}{dx} =\frac{-9-(-3)}{-3-(-6)} =\frac{-6}{3} =-2[/tex]. Now we have the slope, let's input a set of coordinates into the equation so that we can find the constant [tex]b[/tex].
[tex]-9=-2(-3)+b[/tex]
[tex]b=-15[/tex] - Re-arranging to get b
Now re-write the equation as we have the constants.
[tex]y=-2x-15[/tex]
The complex polygon below represents the layout of a parking lot. Find the area of the parking lot in square meters.
Answer:
The area of the parking lot is: 144cm^2
Step-by-step explanation:
Given
See attachment for polygon
Required
The area of the parking lot
The attached plot has 6 congruent triangles with the following dimension;
[tex]Base = 6cm[/tex]
[tex]Height = 8cm[/tex]
[tex]Area = \frac{1}{2} * Base * Height[/tex]
[tex]Area = \frac{1}{2} * 6cm * 8cm[/tex]
[tex]Area = 24cm^2[/tex]
The area of the 6 triangles is:
Area = 6 * Area of 1 triangle
[tex]Area = 6 * 24cm^2[/tex]
[tex]Area = 144cm^2[/tex]

Trevor's mom bought 3 gallons of fruit juice at the store how many fluid ounces of fruit juice did Trevor‘s mom buy?
Answer: 384 fluid ounces
Step-by-step explanation:
First and foremost, when converting gallons to ounces, the conversion rate is:
1 gallon = 128 ounces
Therefore, since Trevor's mom bought 3 gallons of fruit juice, to convert it to to ounces, we have to multiply by 128. This will then be:
1 gallon = 128 ounces
3 gallons = 128 ounces × 3
= 384 fluid ounces of fruit juice.

What is the theoretical probability of rolling a number less than 5? Write the fraction, decimal and percent.
Given:
Rolling a fair dice.
To find:
The theoretical probability of rolling a number less than 5.
Solution:
The possible numbers of rolling a dice are 1, 2, 3, 4, 5, 6.
Total outcomes = 6
Numbers less than 5 are 1, 2, 3, 4.
Favorable outcomes = 4
Now, the theoretical probability of rolling a number less than 5 is:
[tex]\text{Probability}=\dfrac{\text{Favorable outcomes}}{\text{Total outcomes}}[/tex]
[tex]\text{Probability}=\dfrac{4}{6}[/tex]
[tex]\text{Probability}=\dfrac{2}{3}[/tex]
In decimal form, it can be written as:
[tex]\text{Probability}\approx 0.67[/tex]
In percentage form, it can be written as:
[tex]\text{Probability}=\dfrac{2}{3}\times 100[/tex]
[tex]\text{Probability}\approx 66.67%[/tex]
Therefore, the theoretical probability of rolling a number less than 5 in the fraction, decimal and percent are [tex]\dfrac{2}{3}, 0.67[/tex] and [tex]66.67\%[/tex] respectively.
2x – 5x + 16 = –3(x – 6)
Answer:
0
Step-by-step explanation:
2x – 5x + 16 = –3(x – 6)
2x - 5x + 16 = -3x + 18
-3x + 16 = -3x + 18
0x = 1
x = 0
Answer:
x = ∅
Step-by-step explanation:
2x - 5x + 16 = - 3 (x - 6)
combine like terms
- 3x + 16 = - 3 (x - 6)
distribute
- 3x + 16 = - 3x + 18
subtract 3x from both sides
16 = 18
The equation is false and so x = ∅

The number of wins in a season for 32 randomly selected professional football teams arelisted below. Construct a 90% confidence interval for the true mean number of wins in a season.
Mean(x) = sum of 32 observations / 32 = 7.97
Standard deviation( sd )=2.62
Sample Size(n)=32
Confidence Interval = [ 7.97 ± Z a/2 ( 2.62/ Sqrt ( 32) ) ] = [ 7.97 - 1.64 * (0.4632) , 7.97 + 1.64 * (0.4632) ] = [ 7.2,8.7 . What are the steps used to solve this? How did they find their Standard Deviation? Also what does the Z stand for in the confidence interval?
Answer:
A)CI 90 % = [ 7,2103 ; 8,7297]
B) s = √ ∑(xi - xp)²/n-1
c) z is the score for the given significance level in this case is 1,64
Step-by-step explanation:
For a confidence Interval of 90%, the significance level is α = 10 %
α = 0,1 α/2 = 0,05 and from z-table we find z(c) for 0,05 z(c) = 1,64
CI 90 % = [ x ± z(c) * s/√n ]
CI 90 % = [ 7,97 ± 1,64 * 2.62/√32]
CI 90 % = [ 7,97 ± 0,7597]
CI 90 % = [ 7,2103 ; 8,7297]
B) To calculate the standard deviation of the sample the equation is:
s = √ ∑(xi - xp)²/n-1
xi - xp is the difference between each one of the elements of the sample
xp is the mean or average of the elements of the sample and n is the sample size

1. The area of a figure is 32 square centimeters.
Suppose the sides of the figure are doubled. What
will be the new area of the similar figure?
Answer:
128
Step-by-step explanation:
If the area of a figure is 32 square centimeters then the length/breadth could be 8cm and 4cm or 16cm and 2cm.
Let’s assume that the the sides of the figure are doubled, if that’s the case then we would arrive at 8*2 * 4*2 or 16*2 * 2*2 in which 16*8 or 32*4 which will both result to 128 as the answer.
