Hoped this helped! XD

The standard deviation of the means measure describes the standard error of the mean

Statistic is the study of mathematics that deal with relations between comprehensive data.

A standard deviation (or σ) is a measurement of how spread the information is in relation to the mean. A lower standard deviation means data are bunched around the mean, and a high standard deviation implies data are more scattered out, and best describes the error related to or around the mean.

From the above definition it is clear that  standard deviation of the means measure describes the standard error of the mean.

Thus, the standard deviation of the means measure describes the standard error of the mean

Answer:

slope= 11

Step-by-step explanation:

(12,23) = (x1,y1)

(14,45) = (x2,y2)

Now,

slope(m)= (y2-y1)/(x2-x1)

=(45-23)/(14-12)

=22/2

=11

Step-by-step explanation:

Answer:

1 1/2 cups flour. 1 1/3 cup oats. 4/9 cup oats.

Step-by-step explanation:

For every 3/4 cup of flour there is 2/3 cup of oats. So if you have 2/3 cup of oats you would have 3/4+3/4 cups of flour or 1 1/2 cups of flour. If you have 3 cups flour you would have 2/3+2/3 cup oats. Find the last amount by multiplying 1 by 1/3 then dividing by 3/4.

The missing value in the table is 1¹/₂ cups flour. 1¹/₃ cup oats. 4/9 cup oats.

An ordered pair of numbers a and b, represented as a / b, is a ratio if b is not equal to 0. A proportion is an equation that sets two ratios at the same value. The numerical relationship between two values demonstrates how frequently one value contains or is contained within another.

Oats make up 2/3 cup of every 3/4 cup of flour. Therefore, if you have 2/3 cup of oats, you will need 3/4 + 3/4 cups of flour, which is 1 1/2 cups. You would need 2/3 cup plus 2/3 cup of oats for every cup of flour. By multiplying 1 by 1/3 and then dividing by 3/4, you can determine the final sum.

Answer:

x = 85

Step-by-step explanation:

The Pythagorean theorem is a property that is specific to right triangles, or triangles with a right angle. The Pythagorean theorem states the following,

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

Where (a) and (b) are the legs or the sides adjacent to the right angle, and (c) is the hypotenuse or side opposite the right angle.

Substitute in the given values and solve,

[tex]13^2 + 84^2 - x^2\\\\169 + 7056 = x^2\\\\7225 = x^2\\\\85 = x[/tex]

Answer:

Graph included as picture

Step-by-step explanation:

To solve this, plot the given points on the graph

Draw a line through them.

Now select two of those values and we'll find the rate of change.

We'll be using (1,-1) and (3,3)

To find rate of change we will be using the formula: [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

[tex]y_{2} = 3\\y_{1} =-1\\x_{2} = 3\\x_{1} = 1[/tex]

[tex]\frac{3-(-1)}{3-1} = \frac{4}{2} = 2[/tex]

So the rate of change is 2

You will use this rate of change for your other function because they both have the same rate of change

Since we have the rate of change, we can create the slope intercept form formula: y = mx +b

Just substitute for the variables we know

m = rate of change/slope = 2

b = y-intercept = -3

y = 2x + -3

[If you connected all the points in your graph, that's how you found the y-intercept]

Now we have to create the formula for the second function.

We know it will have that same slope of 2

so we have y = 2x + b

To solve for b we can plug in the values we do have which would be (x,y) of (3,6)

6 = 2(3) + b

Now solve

6 = 6 + b

6 (-6) = 6 (-6) + b

0 = b

b = 0

This mean that the y-intercept will be on (0,0)

Plot that point

Now we finish the formula

y = 2x + 0

Connect the dots, make sure the line continues on both of them past the dots and now you have your graph!

I've included a picture of the graph for your reference. I hope this helps, don't be afraid to reach out with further questions!

Step-by-step explanation:

The question is incomplete, as the histogram is not attached.

However, the solution to your question is to select the interval with the highest frequency

Take for instance, after getting readings from the histogram, yiu have:

1 - 10: 8

11 - 20: 5

21 - 30: 11

31 - 40: 2

And so on.......

Interval 11 - 20 will represent the required interval because it has the highest frequency.

Answer:

(-.5,0) and (-1.5,0)

or b= -.5

and b= -1.5

Step-by-step explanation:

First we want one side of the equation to equal 0

we have

4b²+8b+3=0

using the quadratic formula we have

(-b±√(b²-4*a*c))/2a

(-8±√(8²-4*4*3))/2*4

(-8±√(16))/8

(-8±4)/8

now we evaulate when ± is addition

(-8+4)/8

-4/8

-.5

and evaulate once more when the ± is subtraction

(-8-4)/8

-12/8

-1.5

Therefore the two solutions are (-.5,0) and (-1.5,0)

Answer:

Step-by-step explanation:

step one - Move terms to the left side

(4b^2 + 8b + 7 = 4)

(4b^2 + 8b + 7 - 4 = 0)

step dose - Subtract the numbers

(4b^2 + 8b + 3 = 0)

step три - Use the sum-product pattern

(4b^2 + 6b + 2b + 3 = 0)

Answer:

Step-by-step explanation:

Answer:

Step-by-step explanation:

6. Soil volume = area * height = 1/2*4*4*2.5 = 20 cubic ft

7. Concrete volume = length * width * height = 1.8*1.8*3 = 9.72 cubic ft

Block weight = 95*9.72 = 923.4 lb

8. It is unclear but let's assume the ramp consists of 5 pieces.

The total area = 4*6+3.5*(4+6+7.2) = 84.2 sq ft

So it will require a minimum of 85.2/(4*2) = 10.65 or 11 sheets of plywood

Answer:

Step-by-step explanation:

the skateboard ramp only needs 3 pieces: 2x triangle of 4' by 6' and 1x rectangle of 3.5' by 7.2'.

the 2x triangle require 4x6/4x2 = 3 sheets of plywood

the rectangle require 3.5x7.2/4x2 = 3.15 ~4

so minimum is 7 sheets
