A bag of marbles contains 4 red
marbles, 5 green marbles, and 3 blue marbles. Karen takes a marble out, replaces it and pulls another marble,
what is the probability both the first marble is blue
and the second marble is red?

Answer:

s = 16

Step-by-step explanation:

[tex]\frac{s}{4} +12=16[/tex]

step 1 subtract 12 from each side

12 - 12 cancels out

16 - 12 = 4

now we have [tex]\frac{s}{4}=4[/tex]

step 2 multiply each side by 4

[tex]\frac{s}{4} *4=s[/tex]

4 * 4 = 16

we're left with s = 16

Answer:

Step-by-step explanation:

example: 1,2,3 1+2+3=6. 6/3=2 the mean is 2.

Answer:

The mean is the average or the most common value in a collection of numbers. In statistics, it is a measure of central tendency of a probability distribution along median and mode. It is also referred to as an expected value.

Step-by-step explanation:

Mean is an essential concept in mathematics and statistics. The mean is the average or the most common value in a collection of numbers.

How to calculate mean?

There are different ways of measuring the central tendency of a set of values. There are multiple ways to calculate the mean. Here are the two most popular ones:

Arithmetic mean is the total of the sum of all values in a collection of numbers divided by the number of numbers in a collection. It is calculated in the following way:

Answer:

7/20

Step-by-step explanation:

Just multiply the numerators with each other and then multiply the denominators

Answer:

40 mph

Step-by-step explanation:

s = d/t

a to b's distance = 180 miles

7:30 - 12pm = 4.5 hours (time)

speed = 180 ÷ 4.5

speed = 40

Answer:

18

Step-by-step explanation:

Each sandwich will be divided into 6 pieces. 1 sandwich equals 6 pieces, 2 sandwiches equals 12 pieces, so 3 sandwiches equals 18 pieces.

Answer:

It will be 18

All you have to do is simple multiplication, 6 times 3 and you get 18

3 sandwiches and 6 pieces each.

Answer:

6.67<-8

Step-by-step explanation:

-4(r- 2/3) +4= 20/3

20divided by 3 =6.666666667 which rounds to 6.67

6.67 < -8

Hope this is helpful! :)

Answer:

See explanation for answer.

Step-by-step explanation:

−4(r−2/3)+4<−8

−4r+20/3<−8

−4r+20/3−20/3<−8−20/3

−4r<−44/3

−4r/−4<−44/3/−4

Answer: r>11/3

Answer:

A = ( 1 , 2 )

B = ( 4 , 11 )

C = ( 6 , 4 )

D = ( 10 , 9 )

Answer:

A. (1,2), B. (4,11), C. (6,4), D. (10,9)

Step-by-step explanation:

A. On the x line, it is 1 so the number is (1, ?). On the y-line it is 2 so the point is (1,2)

B. On the x line,  it is 4 so the number is (4,?). On the y-line, it is 11 so the point is (4,11).

C. On the x line, it is 6 so the number is (6,?). On the y-line, it is 4 so the point is (6,4).

D. On the x line, it is 10 so the number is (10,?). On the y-line, it is 9 so the point is (10,9).

Answer: Try 5/8

Step-by-step explanation: Because 1/2 and 3/4 can also be written as 4/8 and 6/8. And that's how I got 5/8.

Hi! I believe that I have the answer.

My answer: 5/8.

1/2 can also be put as 4/8. 3/4 can also be put as 6/8. Right in the middle of 4/8 and 6/8 is 5/8.

I hope that helps!

Answer:

Option 3, angle 2 is equal to 37 degrees

Step-by-step explanation:

Angle 2 is on the opposite side of the 37 degree angle, so it is also 37 degrees

Answer: Not enough information is given

Step-by-step explanation:

Data: Angle 4 is 37 degrees

Angle 1 is x degrees

Angle 2 is x degrees

Angle 3 is x degrees

It only shows us that the 1 and 3 or obtuse and 2 is acute

We don't know if the angles are Congruent so we cannot draw a conclusion about the size of any of the other angles

t = 33

Answer:

21. D = 5.67(rounded to the hundredths)

R = 2.84(rounded to the hundredths)

22. D = 13.4

C = 42.08(rounded to the hundredths)

23. C = 33.28(rounded to the hundredths)

R = 5.3

24. D = 1

R = 1.57 or pi/2

Step-by-step explanation:

Formula: C/pi = D

D = 2r

pi = 3.14

21. D = 17.8/3.14 = 5.67(rounded to the hundredths)

R = 5.67/2 = 2.84(rounded to the hundredths)

22. D = 6.7*2 = 13.4

C = 13.4 * 3.14 = 42.08 (rounded to the hundredths)

23. C = 10.6 * 3.14 = 33.28(rounded to the hundredths)

R = 10.6/2 = 5.3

24. D = 3.14/3.14 = 1

R = 3.14/2 = 1.57 or pi/2

Answer:

Using two of the points on the line, you can find the slope of the line by finding the rise and the run. The vertical change between two points is called the rise, and the horizontal change is called the run. The slope equals the rise divided by the run: Slope =riserun Slope = rise run .

Answer:

5:2

Step-by-step explanation:

Triangle LMN's base length is 15 and triangle XYZ's base length is 6. Since they are both base lenghts, you can just use those numbers in a ratio and simply.

15:6

Divide both sides by 3 and you get 5:2!
