Answer:

m∠RUS = 37°

Step-by-step explanation:

In a rhombus, diagonals bisect angles. In other words,

m∠RUS = m∠SUT

Substitute and solve.

10x - 23 = 3x + 19

7x = 42

x = 6

Substitute x = 6 into the equation given for m∠RUS

m∠RUS = (10x-23)

m∠RUS = 37°

Answer:

7 ounces

Step-by-step explanation:

There are 16 ounces in one pound, so there are 17 ounces for the can of nuts.

Since the empty can weighs 3 ounces, you can subtract 17-3, which equals 14, to get the weight of the nuts alone.

Then, you divide 14 by 2, and you get 7.

Answer:

[tex]Total = 11\frac{1}{8}\ cups[/tex]

Step-by-step explanation:

Given

See attachment for plot

Required

Total number of cups used

The number of dot on each dataset represent the number of student

So, to get the total number of cups, we simply add the product of the number of cups and the number of student for each data item

So, we have:

[tex]Total = \frac{1}{8} * 6 + \frac{1}{4} * 5 + \frac{3}{8} * 2 + \frac{1}{2}*0 + \frac{5}{8} * 4 + \frac{3}{4} * 2 + \frac{7}{8} * 5[/tex]

[tex]Total = \frac{6}{8} + \frac{5}{4} + \frac{6}{8} + 0+ \frac{20}{8} + \frac{6}{4} + \frac{35}{8}[/tex]

Solve

[tex]Total = \frac{6+10+6+0+20+12+35}{8}[/tex]

[tex]Total = \frac{89}{8}[/tex]

[tex]Total = 11\frac{1}{8}\ cups[/tex]

Answer:

Mean = 74.4

Median = 81.5

Step-by-step explanation:

25, 40, 68, 85, 95, 98, 70, 78, 85, 100

Mean = Sum of values / Number of values

Number of values = 10

= 25 + 40 + 68 + 70 + 78 + 85 + 85 + 95 + 98 + 100/10

= 744/10

= 74.4

Median

Rearranging the given data

= 25, 40 ,68 ,70 ,78 ,85 ,85 , 95 ,98 ,100

Formula for median = 1/2(n + 1)th value

n = 10

Hence

1/2(10 + 1)th value

1/2(11)th value

= 5.5 th value

This fall between the 5th and 6th value

5th value = 78

6th value = 85

Hence: 78 + 85/2

= 163 / 2

= 81.5

Answer:

Step-by-step explanation:

I don't have graphing facilities but can give you the vertex and 1 other point.

Given a parabola in standard form

y = ax² + bx + c ( a ≠ 0 )

Then the x- coordinate of the vertex is

x = - [tex]\frac{b}{2a}[/tex]

y = - x² - 2x + 8 ← is in standard form

with a = - 1 and b = - 2 , then

x = - [tex]\frac{-2}{-2}[/tex] = - 1

Substitute x = - 1 into the equation for corresponding value of y

y = - (- 1)² - 2(- 1) + 8 = - 1 + 2 + 8 = 9

vertex = (- 1, 9 )

To obtain another point substitute any value for x into the equation

x = 0 : y = 0 - 0 + 8 , then (0, 8 ) is a point on the graph

x = 2 : y = - (2)² - 2(2) + 8 = - 4 - 4 + 8 = 0  then (2, 0 ) is a point on the graph

Answer:

i. Estimated number of free throws of the best player = 0.85 * 40

ii. 34 free throws

Step-by-step explanation:

Percentage of free throws made by the best player = 85%

Percentage of free throws made by the second best player = 75%

Percentage of free throws made by the third best player = 70%

Therefore, for 40 attempts;

i. Estimated number of free throws made by the best player = 85% x 40

                                                         = 0.85 x 40

                                                         = 34

ii. Estimated number of free throws made by the second best player = 75%x 40

                                                                 = 0.75 x 40

                                                                 = 30

iii. Estimated number of free throws made by the third best player = 70% x 40

                                                                   = 0.70 x 40

                                                                   = 28

Thus, the equation that gives the estimated number of free throws is 0.85 * 40.

The best player will make about 34 free throws.

Answer:

A,C,D

Step-by-step explanation:

sorry if incorrect

Answer:

2x+y=3  -->  y= -2x+3

2y-6=x  -->  y= 1/2x+3

x-3y=-6  -->  y= 1/3x+2

-x+1/2y=3  -->  y= 2x+6

Step-by-step explanation:

i hope this helps :)

The solution to the system of equations is

2x + y = 3  ;  y = -2x + 3

2y - 6 = x  ;  y = ( 1/2 )x + 3

x - 3y = -6  ;  y = ( 1/3 )x + 2

-x + ( 1/2 )y = 3  ;  y = 2x + 6

The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept

And y - y₁ = m ( x - x₁ )

y = y-coordinate of second point

y₁ = y-coordinate of point one

m = slope

x = x-coordinate of second point

x₁ = x-coordinate of point one

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

Given data ,

Let the equation be represented as A

Now , the value of A is

a)

Let the equation be 2x + y = 3

Subtracting 2x on both sides of the equation , we get

y = 3 - 2x  

So , the equation in slope intercept form is y = 3 - 2x  

b)

Let the equation be 2y - 6 = x

Adding 6 on both sides of the equation , we get

2y = x + 6  

Divide by 2 on both sides of the equation , we get

y = ( 1/2 )x + 3

So , the equation in slope intercept form is y = ( 1/2 )x + 3

c)

Let the equation be x - 3y = -6

Adding 3y on both sides of the equation , we get

x = 3y - 6  

Adding 6 on both sides of the equation , we get

3y = x + 6

Divide by 3 on both sides of the equation , we get

y = ( 1/3 )x + 2

So , the equation in slope intercept form is y = ( 1/3 )x + 2

d)

Let the equation be -x + ( 1/2 )y = 3

Adding x on both sides of the equation , we get

( 1/2 )y = 3 + x

Multiply by 2 on both sides of the equation , we get

y = 2x + 6

So , the equation in slope intercept form is y = 2x + 6

Hence , the equations are solved

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

Explanation:

a1 = first term

a2 = second term

a3 = third term

and so on, until we reach a37 to represent the 37th term

We don't know the first term, but we'll call it x for now. We'll also let d be the difference between each adjacent term, aka the common difference.

Meaning that,

and so on, until,

---------------------

Add up the first three terms (a1 through a3) and set the sum equal to 12

Then do a bit of algebra to get

a1+a2+a3 = 12

(x)+(x+d)+(x+2d) = 12

3x+3d = 12

3(x+d) = 12

x+d = 12/3

x+d = 4

x = 4-d

Do the same for the last three terms, but the sum here is 318

a35+a36+a37 = 318

(x+34d)+(x+35d)+(x+36d) = 318

3x+105d = 318

3(x) + 105d = 318

3(4-d)+105d = 318 .... replace x with 4-d; isolate d

12-3d+105d = 318

102d+12 = 318

102d = 318-12

102d = 306

d = 306/102

d = 3

The common difference is 3. It means each term is increasing by 3.

Use this value of d to find x

x = 4-d

x = 4-3

x = 1

The first term is 1. That makes the second term x+d = 1+3 = 4, then the third term is x+2d = 1+2*3 = 7, and so on.

The sum of the first three terms is 1+4+7 = 12. That helps partly confirm the answer.

Also we have,

Or you could note that the 35th term is 103, and then you increase by 3 each time to get the remaining two terms.

The last part of the confirmation is adding up those three last terms: 103+106+109 = 318, so the answer is fully verified at this point.

Side note: An arithmetic sequence never ends. There technically is no "last term"; however, since we're confined to focusing on these specific 37 terms, we can get away with using the phrasing.

Correct answer: (Standard Deviation of means)

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
