What's the probability of rolling a prime number on a fair die
Answers
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%
A circle has a radius of 6ft. What is the area of the sector formed by a central angle measuring 300 degrees
Answers
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

B. No correlation

c. Positive correlation
Answers
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.

Can someone help me with this please? In Belleville, the library is due south of the courthouse and due west of the community swimming pool. If the distance between the library and the courthouse is 9 miles and the distance between the courthouse and the city pool is 15 miles, how far is the library from the community pool?
Answers
Answer:
12 miles
Step-by-step explanation:
A right triangle is formed, where the distance between the library and the courthouse is one leg ( = 9 miles), the distance between the library and the swimming pool is the other leg (let's call it x), and the distance between the swimming pool and the courthouse is the hypotenuse ( = 15 miles).
From Pythagorean theorem:
15² = 9² + x²
225 - 81 = x²
x = √144
x = 12 miles
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 ?
Answers
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.
Which of the following could represent the scale factor of the smaller figure to the larger figure?

20pi:125pi

2:5
Answers
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.

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?
Answers
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
