Answer:

80

Step-by-step explanation:

let's look at the probability. There is a 5/8 chance of the spinner landing on an odd number. you would multiply the 128 by 5/8 to get your estimate of 80 times the spinner will land on an odd number. Hope this helps! :)

Answer:

C

Step-by-step explanation:

When the expression has an equal sign there is only one solution

6x = 150

* divide each side by 6 *

6x / 6 = x

150 / 6 = 25

we're left with x = 25

The answer would be C, because the dot is in between 24 and 26 which would be 25 and x equals 25

Explanation: PEMDAS

Answer:

Point T(x, y) is translated 71 units up and then rotated 180° about the origin

Point U(x, y) is rotated 90° counterclockwise, then translated 124 units up.

Point V(x, y) is reflected about the y axis, then translated 8831 units to the left.

Step-by-step explanation:

Transformation is the movement of a point from its initial location to a new location. Types of transformation are rotation, reflection, translation and dilation.

If a point R(x, y) is vertical stretched by a factor of 38 followed by a horizontal stretch of 7, the new point is at R'(x/7, 38y). That is (x, y) ⇒ (x/7, 38y).

If a point S(x, y) is translated 9 units to the right, the new point is (x + 9, y), if it is reflected over the y axis, the new point is S'(-x-9, y). That is (x, y) ⇒ (-x-9, y).

If a point T(x, y) is translated 71 units up, the new point is at (x, y + 71), if it is rotated 180° about the origin, the new point is at T'(-x, -y - 71). That is (x, y) ⇒ (-x, -y - 71).

If a point U(x, y) is rotated 90° counterclockwise, the new point is at (-y, x), if it is then translated 124 units up, the new point is U'(-y, x + 124).

If a point V(x, y) is reflected about the y axis, the new point is at (-x, y), if it is then translated 8831 units to the left, the new point is V'(-x - 8831, y).

Answer:

The expected win of a coin flip in dollars is 1.25.

Step-by-step explanation:

To find the expected win of a coin flip, we multiply the probability of each outcome by their earnings, and then add them.

We have that:

3/4 probability of heads. If heads, you win $2.

1/4 probability of tails. If tails, you lose $1.

What is the expected win of a coin flip in dollars?

[tex]E = 2\frac{3}{4} - 1\frac{1}{4} = \frac{2*3 - 1*1}{4} = \frac{6-1}{4} = \frac{5}{4} = 1.25[/tex]

The expected win of a coin flip in dollars is 1.25.

Answer:

35

Step-by-step explanation:

For most questions asking for the area of a part of a figure, you first have to find the area of the figure then divide to get the part. Because the water level is 2/3 up, we can divide by 3 and that would make it the needed 1/3.

Volume of a rectangular prism: L*W*H

3 3/4 * 3 3/8 * 13 1/3

Becomes

168 3/4

Then divide by 3

56 1/4

or

56.25

Answer:

v = 56.25ft³

Step-by-step explanation:

Total volume

v = 3 3/4 * 13 1/3 * 3 3/8

v = 15/4 * 40/3 * 27/8

v = 16200 / 96

1/3 without water

v = (16200 / 96) * (1/3)

v = 16200 / 288

v = 56.25ft³

The y- intercept is 3.

A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the change in y coordinate with respect to the change in x coordinate as,

m = Δy/Δx where, m is the slope

Given:

18x−6y=12

Writing the above equation in slope- intercept form

6y = 18x - 12

y= 18x /6 - 12/ 6

y= 3x - 2.

So, the slope of perpendicular line is -1/3 and passes through (6, 1)

y= mx+ c

1 = -1/3 (6) + c

1 = -2 + c

c= 3

Hence, the y- intercept is 3.

Answer:

The price that is two standard deviations above the mean price is 4.90.

Step-by-step explanation:

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.

Mean of 3.22 and a standard deviation of 0.84.

This means that [tex]\mu = 3.22, \sigma = 0.84[/tex]

Find the price that is two standard deviations above the mean price.

This is X when Z = 2. So

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]2 = \frac{X - 3.22}{0.84}[/tex]

[tex]X - 3.22 = 2*0.84[/tex]

[tex]X = 4.9[/tex]

The price that is two standard deviations above the mean price is 4.90.

Answer:

[tex]y = -5[/tex]

Step-by-step explanation:

Given

[tex]B = (7,-3)[/tex]

[tex]C = (6,y)[/tex]

[tex]A = (4,-9)[/tex]

Required

The y coordinate of C

Since A, B and C are on the same line, the slope of AB and the slope of AC will be the same.

Slope (m) is calculated as:

[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

For AC

[tex]A = (4,-9)[/tex]     [tex]C = (6,y)[/tex]    

[tex]m = \frac{y - -9}{6 - 4}[/tex]

[tex]m = \frac{y +9}{2}[/tex]

For AB

[tex]A = (4,-9)[/tex]       [tex]B = (7,-3)[/tex]

[tex]m = \frac{-3 --9}{7-4}[/tex]

[tex]m = \frac{-3 +9}{3}[/tex]

[tex]m = \frac{6}{3}[/tex]

[tex]m = 2[/tex]

So, we have:

[tex]m = \frac{y +9}{2}[/tex] and [tex]m = 2[/tex]

[tex]m = m[/tex]

[tex]\frac{y +9}{2} = 2[/tex]

Multiply both sides by 2

[tex]y +9 = 4[/tex]

Solve for y

[tex]y = 4-9[/tex]

[tex]y = -5[/tex]

Hence, the y coordinate of C is -5
