Which of the following could represent the scale factor of the smaller figure to the larger figure?
4:25
6pi:15pi
8:125
20pi:125pi
16pi:250pi
2:5
Answer:
It could be 2:5 or 6pi:15pi
Step-by-step explanation:
If you write the ratio of the surface area as a fraction, you would get [tex]\frac{20\pi *yd^{2} }{125\pi *yd^{2} }[/tex]. Simplifying it would leave [tex]\frac{4}{25}[/tex]. But this is NOT the answer because that is the ratio of the surface area. You have to square root it to find the scale factor. The square root is [tex]\frac{2}{5}[/tex]. The answers would be 2:5 and 6pi:15pi.
Answer:
6π : 15π
2 : 5

approximated by a line with a positive slope. What type of correlation does
this represent?
O
A. Negative correlation
O
B. No correlation
O
c. Positive correlation
Answer: A. Negative correlation
Step-by-step explanation:
A P E X
The scatterplot that represents the monthly values of stock ABC can be approximated by a line with a positive slope represents positive correlation. The correct option is C.
What is correlation?The relationship between variables is described by correlation. It can be either strong or weak, as well as positive or negative.
Correlations show that there is a relationship between two variables, but one does not always cause the other to change.
A positive correlation indicates that as one variable increases, so does the other.
In this case, the scatterplot of the monthly values of stock ABC can be approximated by a line with a positive slope, indicating that as the stock's value increases over time, so does the corresponding month. As a result, it is a positive correlation.
Thus, the correct option is C.

Ellie’s eats 1/4 cups of raisins everyday. If she buys a package that has 6 cups of raisins,how many days of raisins is that ?
Answer:
24
Step-by-step explanation:
Answer:
24 days
Step-by-step explanation:
Alright, so you can set an equation where x is the amount of days this package of raisins can last. Your equation would be 6=1/4x. Now, you solve. Bring the 1/4 over by dividing both sides by it. You get x=24, which is the answer.
From the numbers 1, 2, 3, 4, 5, what is the probability of choosing an even number at random?
Answer:
2/5
Step-by-step explanation:
There are only 2 even number in the set out of 5 numbers.
The probability of selection even number at random is 2/5.
What is probability?
Probability is possibility that deals with "occurrence of random event at a time".
According to the question,
From the numbers 1,2,3,4,5
Number of sample space = 5
Number of even numbers = 2
Probability of an event = [tex]\frac{sum of favorable events}{Total number of events}[/tex]
In order to find probability of selection even number at random:
=2/5.
Hence, the probability of selection even number at random is 2/5.

What's the probability of rolling a prime number on a fair die
Answer:
50% chance
Step-by-step explanation:
if it's a six-sided die, the options are 2, 3, and 5. that's three numbers out of six, or half (50%)
Answer:
1/2 ; 50%
Step-by-step explanation:
Probability is number of desired outcomes/number of total outcomes.
In a fair die, there are 6 total outcomes.
Now, let's find how many desired outcomes there are.
We can do this by naming the prime numbers form 1-6.
Prime numbers are numbers that are divisible by 2 positive integers: 1 and itself.
This means that 1, 4, and 6 are not prime numbers.
The prime numbers are: 2, 3, and 5.
So there are 3 desired outcomes.
That means the probability would be 3/6
This can be simplified to 1/2, or 50%

find the volume, help please all numbers are in inches, will mark brainleist
Prism volume will be base area times height. We have a right triangular base, so its area is half the product of its legs, area (1/2)(6)(8)=24. The prism has a height 13. Multiplying we get a volume of 24×13 = 312 cubic inches.

A circle has a radius of 6ft. What is the area of the sector formed by a central angle measuring 300 degrees
Answer:
30π ft^2 which is 94.25 ft^2 to the nearest hundredth.
Step-by-step explanation:
The area of the full circle is π * 6^2
= 36π so:
the area of the 300 degrees sector = 300 * 36 π / 360
= 30 π
A square has one of its sides increased by 7 inches and the other side decreased by 4 inches. Which of the following represents the area of the square?
Answer:
Step-by-step explanation:
both the length and the width of a square is the same measurement.
so if both measured to "x" then that means one side increase +7.
so one side is x + 7
and the other side decreased -4
so the other side is x - 4
area of square = length x width or just one of the sides to the power of 2
so (x+7) * (x-4) = Area
x^2 + 3x - 21 = area
Answer:
x^2-11x+24
Step-by-step explanation:
The area of a quad is lw
So, the formula would be (x-7)(x-4)
When you multiply it, it turns to be x^2 - 11x + 24

Help solve for X, please hurry I have 42 minutes
Answer:
A) 9
Step-by-step explanation:
First you need to find the measure of angle c
Since it's a quadrilateral, the interior angles add up to 360 degrees
Now there's two right angles and one 99 degree angle
Add those and subtract from 360
360 - (90+90+99) = 81
C = 81 degrees
However x is the root of c so root 81 is 9
