Answer:

3/5

Step-by-step explanation:

There are 12 window seats and 8 aisle seats giving us a total of 20 seats.

12/20 = 3/5

Therefore, the probably the next person will be assigned a window seat is 3/5.

Answer:

Lily spent $19.20, Sue spent $4.80. Make sure to include the units.

Step by Step:

Lets say Sue is X

4x+x=24

5x=24

x=24/5

x=4.8

So sue spent 4.8.

24-4.8=19.2

Lily spent 19.2

Check:  4(4.8)=19.2

19.2+4.8=24

Answer:

y = -7

Step-by-step explanation:

The line represents the y-coordinate, because it is a straight line over the x axis, indicating it cant be an x coordinate

Because it is 7 units below the x-axis, it is -7

y = -7

Answer:

s+18=120

s=102

Step-by-step explanation:

Basically, she had 120 after everything was done, so we know 120 is on the right side of the equal sign. We know she had an unknown number of songs and after she added 18 it was 120. That means the equation is s+18=120

Now to solve it is simple, just isolate s by subtracting 18 on both sides.

s+18=120

-18       -18

s=102

Answer:

Part (A)

We have 6 red and 4 blue marbles, so 6+4 = 10 total.

The probability of getting red is 6/10 since we have 6 red out of 10 total.

The probability of getting another red is 5/9 because we don't put the first marble back.

The probability of getting two reds in a row is (6/10)*(5/9) = 30/90 = 1/3

========================================================

Part (B)

4/10 represents the probability of getting blue on the first try

3/9 represents the probability of getting a blue marble on the second try

We don't put the marble back.

(4/10)*(3/9) = 12/90 = 4/30 is the probability of getting two blues in a row.

========================================================

Part (C)

Add up the results of parts (A) and (B)

1/3 + 4/30

10/30 + 4/30

(10+4)/30

14/30

7/15

The result 7/15 is the probability of either getting two reds OR getting two blues (pick one case only). This tells us that 7 out of 15 times we'll have this happen. This must mean the remaining 8 times will have two marbles of different colors.

So 8/15 is the probability of picking one marble of each color.

------

As an alternative, we could also consider it like this

(6/10)*(4/9) = 24/90 = 4/15

This represents the probability of picking red first, then blue next.

Similarly,

(4/10)*(6/9) = 24/90 = 4/15

represents the probability of picking blue first, then red next.

Therefore, 4/15+4/15 = 8/15 is the probability of getting one of each color.

Answer:

Correlation coefficient for the data in the table was found to be 0.93

Step-by-step explanation:

The correlation coefficient for the data in the table is 0.93.

The correlation coefficient is used to measure the relationship that exists between two or more variables. If two variables have a positive correlation, as one of the variable increases, the other variable increases. If one of the variable decreases, the other variable decreases.

When calculated on a financial calculator, the correlation coefficient is 0.93.

Answer:

Mean = 10

Variance = 30.89

Standard Deviation = 5.56

Step-by-step explanation:

Find the Mean, Variance and Standard deviation

6, 14, 8, 2, 11, 7, 12, 4, 18, 18

Step 1

We rearrange the data and find the Mean

2, 4, 6, 7, 8, 11, 12, 14, 18, 18

Mean = Sum of values/Number of values

= 2 + 4+ 6+ 7+ 8 + 11 + 12 + 14 + 18 +18/10

= 100/10

= 10

Step 2

We find the variance of this sample days ma

Variance = (x - Mean)²/n - 1

n = 10

Hence,

=( (2 - 10)² +(4 - 10)²+ (6 - 10)²+ (7 - 10)² + (8 - 10)² + (11 - 10)² + (12 - 10)² + (14 - 10)² + (18 - 10)² +(18 - 10)²) /10 -1

= ( 64 + 36 + 16 + 9 + 4 + 1 + 4 + 16 + 64 +64)/9

= 278/9

= 30.88888889

Approximately = 30.89

Step 3

Standard Deviation = √Variance

= √30.89

= 5.5578772926

Approximately = 5.56

Answer:

[tex]32\:\mathrm{feet}[/tex]

Step-by-step explanation:

The square forms two 45-45-90 triangles, where the diagonal of the square is the hypotenuse of both these triangles. In all 45-45-90 triangles, the sides are in the ratio [tex]x:x:x\sqrt{2}[/tex], where [tex]x\sqrt{2}[/tex] is the hypotenuse of the triangle and [tex]x[/tex] represents each of the two other sides of the triangle (from the Pythagorean Theorem).

Thus, we know that [tex]8\sqrt{2}[/tex] represents the hypotenuse, which means that the side length must be [tex]8[/tex] feet. The perimeter is then [tex]4\cdot 8=\boxed{32\:\mathrm{feet}}[/tex]

Answer:

y = (-3/4)x + 7

Step-by-step explanation:

Answer:

y = -3/4x - 7

Step-by-step explanation:

Slope Intercept form: y=mx + b where m = slope and b = intercept.

Isolate y.

9x + 12y = -84

-9x             -9x (subtract 9x from both sides)

12y = -9x - 84

(divide by 12)

y = -9/12x - 7

(simplify fraction)

y = -3/4x - 7
