What are you asking?

Step-by-step explanation:

Answer:

I and III only. Got it correct on Stats test.

Thus, the mean of this new distribution is 168 + 117 and the standard deviation of this new distribution is 5+7. Therefore, option C is the correct answer.

Given that, at King Kong High School, the average weight of senior boys is 168 lbs.

Standard deviation is the positive square root of the variance. Standard deviation is one of the basic methods of statistical analysis. Standard deviation is commonly abbreviated as SD and denoted by 'σ’ and it tells about the value that how much it has deviated from the mean value.

Here, a new distribution is created by adding the boys' weights and the girls' weights together.

So, the new average weight of senior boys and girls

= 168+117

= 285 lbs

The new standard deviation is 5+7

= 12 lbs

Thus, the mean of this new distribution is 168 + 117 and the standard deviation of this new distribution is 5+7. Therefore, option C is the correct answer.

Answer:

6.50w

Step-by-step explanation:

Given that :

Weight ________ Cost ($)

1 ______________6.50

2 _____________ 13.00

3 _____________ 19.50

Cost of package that weighs w pounds

If one pound = 6.50

2 pounds = 13.0

Then, the cost per pound = $6.50

Hence, cost of package that weighs w pounds will be ;

$6.50 * w = $6.50w

Answer:

20,000

Step-by-step explanation:

It is right on plato/edmentum

You just take 75,000-50,000=25,000 and then since it is dividend paid you will subtract the 5,000 from 25,000 and then you will get 20,000.

So 20,000 is your answer. :)

Answer:

454

Step-by-step explanation:

The formula for this arithmetic sequence is: 9n+4

1st term: 9(1)+4 = 13

2nd term: 9(2)+4 = 22

3rd term: 9(3)+4 = 31

4th term: 9(4)+4 = 40

.

.

.

50th term: 9(50)+4 = 450+4

                                = 454

Answer:

y = -6x + 7

Step-by-step explanation:

In this question, we need to find the equation of a line with the given information.

We know that the line passes through (2, -5).

We also know that the line is parallel to the line 6x + y = 6, which means that it has to have the same slope.

To make it simpler to understand, we can change the equation into slope format:

y = -6x + 6

This means that our new line should have a slope of -6.

With the information above, we can plug in our new values to get the y-intercept of our equations, since we don't have that information.

Plug in your slope and coordinates to the y = mx + b equation and solve for b:

-5 = -6(2) + b

-5 = -12 + b

Add 12 to both sides.

7 = b

Our y-intercept would be b.

Now, we can plug in all our information to get our new equation:

y = -6x + 7

Your answer would be y = -6x + 7

Answer:

It would be C or B

Step-by-step explanation:

can't be A because A is 0 and there is no way you could be able to draw 0 lines so it would most likely be C

Answer:

[tex]x<-6[/tex]

Step-by-step explanation:

[tex]3x-2>5x+10[/tex]

Add 2 to both sides

[tex]3x-2+2>5x+10+2[/tex]

Simplify

[tex]3x>5x+12[/tex]

Subtract [tex]5x[/tex] from both sides

[tex]3x-5x>5x+12-5x[/tex]

Simplify

[tex]-2x>12[/tex]

Multiply both sides by [tex]-1[/tex] (reverse the inequality)

[tex](-2x)(-1)<12(-1)[/tex]

Simplify

[tex]2x<-12[/tex]

Divide both sides by [tex]2[/tex]

[tex]\frac{2x}{2} <\frac{-12}{2}[/tex]

Divide the numbers: [tex]\frac{2}{2} =1[/tex]

[tex]=x[/tex]

Divide the numbers: [tex]\frac{-12}{2}[/tex]

Apply fraction rule: [tex]\frac{-a}{b} =-\frac{a}{b}[/tex]

[tex]=\frac{12}{2}[/tex]

Divide the numbers: [tex]\frac{12}{2} =6[/tex]

[tex]=-6[/tex]

[tex]x<-6[/tex]

Answer:

x < -6

I just took the test. When you are dividing by a negative variable, flip the sign.

Answer:

The sketch tool to indicate what Edwin is describing as the parabola's "turning point'' is described below in details.

Step-by-step explanation:

We can see in graph that it intersect X axis and it is open upward it means turning point is below X axis, we can find turning point by find maximum value of Y If open downward and minimum value, if open upward here we can find that minimum point is (3, -5). also you can draw axis of symmetry parabola and finds its intersection with turning point can also be named vertex of parabola.

Answer:

94 degrees

Step-by-step explanation:

triangle is 180

so 180-74-20=86

The exterior angle is 74+20=94

94 is exterior angle

Answer:

x = 94°

Step-by-step explanation:

Any triangle has three angles whose measures add up to a total of 180°.

This triangle has two known angle measures. First, find the missing interior angle measure.

180 - (74 + 20)

180 - 94

86

The missing interior angle's measure is 86°. An exterior angle is supplementary to its adjacent interior angle, which means that the measure of the interior angle plus the exterior angle measure is 180.

180 - 86

94

Another way to find out a missing exterior angle measure is to simply add the measures of the two nonadjacent interior angles.

74 + 20

94

I hope this helped :)

Answer:

Step-by-step explanation:

We can immediately elimate two answers since x cannot be larger than the hypotenuse, which is 9. You can cosine = adjaent/hypotenuse, which gives the equation cos(54) = x/9, which simplifies to x = 9*cos(54). When you plug this into a calculator, you should get 5.29. Keep in mind that 54 is measured in degrees and not radians because.

Answer:

D.) x = 5.29

Step-by-step explanation:

first find the last angle measure 180-90-54=36

use law of sines to find x

sin90/9=sin36/x

(sin90)(x) = (sin36)(9)

(sin90)(x) = 5.29

x = 5.29

Answer:

[tex]y = \frac{3}{2} x-8[/tex]

Step-by-step explanation:

Firstly, let's get y by itself in the equation.

[tex]y = \frac{3}{2}x + 5[/tex]

Parallel lines have the same slope, but not the same y intercept. So we have an equation like this:

[tex]y = \frac{3}{2}x + b[/tex]

To find b (aka the y-intercept), we need to plug in the ordered pair into the equation like this:

[tex]-5 = \frac{3}{2}(2) + b[/tex]

Now solve:

[tex]-5 = \frac{6}{2} + b\\-5 = 3 + b\\-8 = b[/tex]

We have found the y-intercept, now we can write the full equation:

[tex]y = \frac{3}{2} x-8[/tex]

Answer:

4 * 14 = 56

Step-by-step explanation:

56/2 = 28

28/2 = 14

14/2 = 7

7/7 = 1

56 = 2 * 2 * 2 * 7

56 = (2 * 2) * (2 * 7)

56 = 4 * 14
