a bag holds 4 red, 5 yellow, and 3 purple marbles. what is the probability of choosing a purple marble.

A: 1/6
B: 6/18
C: 3/20
D: 1/19

Answer:

1/3

Step-by-step explanation:

hope this helps!

Answer:

You find the mean by adding all the numbers together then divide the sum of that by the amount of numbers there are. You find the median by looking at the middle number. You find the mode by looking at the most used number. You find the range by subtracting the highest and lowest numbers.

Step-by-step explanation:

say you have these numbers ( 8, 7, 17, 12, 0, 9, 11, 5, 8)

Mean:

8 + 7 + 12 + 17 + 0 + 9 + 11 + 5 + 8 = 77

77 ÷ 9 = 8.5

Median: 0

Mode: 8

Range: 17 - 0 = 17

Answer:

median is the middle number

but if the are two numbers in middle u add those two n divide by 2

range is the biggest number subtract lowest number

mean is total average divide by the number of data

mode is the number that appears many times

Answer:

The hypotenuse is 25 inches.

Step-by-step explanation:

This is a right triangle, so the Pythagorean Theorem applies.

I will assume you know about the Pythagorean Theorem, therefore I will not define it.

Here, I am solving for the hypotenuse.

[tex]a^2+b^2=c^2[/tex]

[tex]24^2+7^2=c^2[/tex]

[tex]576+49=c^2[/tex]

[tex]625 = c^2[/tex]

[tex]25=c[/tex]

Answer:

25

Step-by-step explanation:

To find the hypotenuse, you need to use a^2+b^2=c^2

Plugging the numbers in, the equation is

24^2+7^2=c^2

From here, you can just solve the equation, simplifying it equals

576+49=c^2

Add the two values

625=c^2

from here, you would square both sides to get c standing alone. This results in the equation finishing with the answer:

25=c

or flipping it around to make sence

c=25

Hope this helps! Have a good rest of your day!!!

Answer:

Future Value= 18,478 people

Step-by-step explanation:

eGiving the following information:

Present value (PV)= 10,173

Growth rate (g)= 0.089 every 10 years

Number of periods (n)= 7

To calculate the population in 2020, we need to use the following formula:

FV= PV*(1 + g)^n

FV= 10,173*(1.089^7)

FV= 18,478 people

Answer: B: 1/5

Step-by-step explanation: To find the probability of a students favorite class being history, we add all of the students to a sum. When added correctly, you should have a sum of 60 students. The next thing we do is create a fraction of the amount of students that enjoy history. This makes our answer 12/60. While this is correct, it makes any other possible calculations a bit more difficult so we must simplify it. To simplify you simply divide the fraction until you can no longer divide it with common factors. So I divided 60 by 12 to get 5. Knowing that this is one number, we would put 1 as a numerator and 5 as the denominator. This means our answer is 1/5 or B.

Answer:

Use multiplication (V = l x w x h) to find the volume of a solid figure.

Step-by-step explanation:

Answer:

answer: A

Because when doing area for triangles its

base × height ÷ 2 so for 1 triangle it would be 5 × 4 = 20 then ÷ by 2 so 20 ÷ 2 = 10 Since there are 4 triangles we will have to add 10 4 times and then for the square it's easily just 4 × 4 = 16

so it would come out to 16 + 10 + 10 + 10 + 10 =

Answer:

mn + mp

Step-by-step explanation:

m(n + p) =

m(n) + m(p) =

mn + mp

Hope that helps! :)

The equivalent expression for the algebra m(n+p) is mn + mp.

Equivalent expressions are similar expressions that when being solved provide the same solution. Equivalent expressions are used widely in the expansion of algebraic equations.

From the given information, we have:

=  m(n + p)

To determine the equivalent expression for the above algebraic equation, we need to expand the bracket as follows:

= m(n) + m(p)

= mn + mp

Answer:

66.67 in^3

Step-by-step explanation:

volume of a cylinder = nr^2h

Volume of a cone =  1/3(nr^2h)

n = 22/7

r = radius

the volume of a cone is 1/3 that of a cylinder

volume of the cone = 1/3 x (200) = 66.67 in^3

Answer:

y = -3x

An explanation is not needed for this is quite simple.

(Sorry for my bad English, I'm Japanese, lol.)

If you mean factoring in general,

x(x²+1)

4y²(-4y+1)

x³+x

= x(x²+1)

Have the greater exponent in front so 4y²-16y³​ will become -16y³​+4y²

−16y³+4y²

= 4y²(−4y+1)

Answer:

x = 76

Step-by-step explanation:

The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.

152° is an exterior angle of the triangle , then

x + x = 152

2x = 152 ( divide both sides by 2 )

x = 76

Answer:

x+x=152° (sum of two opposite interior angles is equal to exterior angle)

2x=152°

x=76 °
