128 * [tex]\frac{5}{8}[/tex]  =  80

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:3.8c+3.5b+2.9s=total cost 19.38$

Step-by-step explanation:

Answer:

u = 143º

Step-by-step explanation:

Sum of angles in a triangle is 180

The unknown angle IN the triangle

x + 90 + 53 = 180

x + 143 = 180

x = 37º

x and u are supplementary angle which total 180

u + 37 = 180

u = 143º

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

Answer:

x=5/8+1/9

x=53/72

Answer:

Part A) The independent variable is the hours that Tiya mows her neighbor's lawn, and we can denote that with x. It's the variable that isn't affected by other factors. The dependent variable is the amount of money Tiya earns, which we can denote with y. The dependent variable is the variable that is affected by other factors. The amount of money Tiya makes depends on how many hours she works.

Part B) As stated in part A, x is the hours and y is the money earned. The ordered pairs are in (x, y) form, with x being the hours and y being the money earned. For example, if Tiya worked one hour, x would be 1. As she earns 7 dollars per hour, she would earn 7 dollars (1*7), which is y. Therefore, one ordered pair could be (1, 7). Two hours would give Tiya 14 dollars, so we have another pair of (2, 14). Three hours would give Tiya 21 dollars, so we have (3, 21). We can do that for any numbers.

Part C) With every hour, Tiya earns 7 dollars. In order to find y, which is the amount of money totally earned, we multiply x by 7 (7 dollars per hour). Therefore, y = 7x.

The variables are:

And the proportional relation that relates them is:

y = $7*X

The only information that we know is that Tiya earns $7 per hour, so the only variables that we can use are money and time.

The independent variable will be time, because she can decide how much time can she work. The dependent variable is money, because how much she earns depends on how many hours she works.

The ordered pairs are of the form (number of hours, money).

Some examples for this case are:

We define the variables.

Because she wins $7 per hour, the proportional equation will be:

y = $7*x

Answer:

517.2

Step-by-step explanation:

It has sides you're not seeing so don't forget those.

You need to find the area of the front, back, two sides, and bottom

Front & back:

6*5.2* 1/2

31.2/2 = 15.6 for each

Sides:

27*6 = 162 each

Bottom:

6*27 = 162

162+162+162+15.6+15.6= final answer

Answer: B

Step-by-step explanation:

First, you do 5.2 times 6 divided by two which is 15.6. Now you do 15.6 times two since there are two triangles and get 31.2. Now you do 27 times 6 times two and get 324 + 31.2 = 355.2. Lastly, you do 27 times 6 to get 162. 162+355.2 = 517.2

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.

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:

[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

Answer:

A line parallel has the same slope, so -3

The slope of the line that is parallel to line f is -3.

The given line f has a slope of -3.

We need to find the slope of the line that is parallel to line f.

The slope of parallel lines. The slope of parallel lines is equal. The parallel lines are equally inclined with the positive x-axis and hence the slope of parallel lines is equal. If the slopes of two parallel lines are represented as [tex]m_{1}[/tex], [tex]m_{2}[/tex] then we have [tex]m_{1}=m_{2}[/tex].

So, the slope of the parallel line=-3

Therefore, the slope of the line that is parallel to line f is -3.
