Which equation is parallel to y = -9x -8

Answer:

Step-by-step explanation:

The  following are not true:

H. The length of RT = 24 in

J. The length of Q = 30 in

Answer:

H and J are false

Step-by-step explanation:

The triangles are proportional meaning you can cross multiply to find q

30/42 20/q

20*42 = 30q

840 = 30q

q =28

Answer:

[2, 5]

while ( ) these mean that they dont include the x, like idrk how to explain it D: but thats my best explanation

Answer: 1200 pennies

Step-by-step explanation:

Let x be the number of pennies Yoko's bank can hold.

We can set up an equation representing the information given.

[tex]\frac{2x}{5} + 320 = \frac{2x}{3}[/tex]

We can multiply both sides by 15:

6x + 4800 = 10x

Combine like terms:

4x = 4800

Divide both sides by 4:

x = 1200

The sample size must be large enough to support an assumption that the sampling distribution of the sample proportion is approximately normal. Therefore, the correct answer is option is C.

In order to use the normal approximation, we consider both np and n( 1 - p ). If both of these numbers are greater than or equal to 10, then we are justified in using the normal approximation.

While conducting a one-sample test, the population proportion is taken as p and the given sample size is n.

For the sample data to be used for the normal approximation

n×p≥10 and

n(1-p)≥10

Condition should be met.

That means when the np and n(1-p) value is greater than 10, the entire sample can be said to behave like a normal distribution.

This can be regarded as a general rule of thumb, and typically the larger the values of np and n(1-p), the better is the approximation.

Therefore, the correct answer is option is C.

B) The sample size must be large enough to support an assumption that the distribution of the sample is approximately normal.

C) The sample size must be large enough to support an assumption that the sampling distribution of the sample proportion is approximately normal.

D) The sample size must be large enough to support an assumption that the observations are independent.

E) The sample size must be large enough to support an assumption that the sample proportion is an unbiased estimator of the population proportion.

Hello.

Let's solve this problem.

First, multiply 2 times 3x:

6x

Now, add 7 plus 8:

15

Write the expression:

6x+15

Can this expression be simplified any further?

No.

Why?

Because variables and constants are not like terms.

In this case, the variable is x, and the constant is 15.

Answer:

  1:  y = 2x -4

Step-by-step explanation:

The perpendicular bisector of the given segment is the line through its midpoint that has a slope that is the opposite reciprocal of the segment's slope.

The slope of the given segment can be found using the slope formula:

  m = (y2 -y1)/(x2 -x1)

  m = (6 -2)/(0 -8) = 4/-8 = -1/2

The opposite reciprocal of this is ...

  m' = -1/(-1/2) = 2 . . . . (eliminates answer choices 2 and 3)

__

The midpoint of the given segment is ...

  (A+B)/2 = (8 +0, 2 +6)/2 = (4, 4)

__

The y-intercept of the perpendicular bisector can be found from ...

  b = y -mx

  b = 4 -(2)(4) = -4

Then the equation of the perpendicular bisector is ...

  y = 2x -4

Answer: (5a+b)/2

Step-by-step explanation:

1. First factor 5a^2+36ab+7b^2

=(5a+b)(a+7b)

2. Factor 2a+14b

The two can be factored out, making the equation equal to 2(a+7b).

The factored out equation is now [tex]\frac{(5a+b)(a+7b)}{2(a+7b)}[/tex]

Since there is an (a+7b) on both sides of the fraction, they cancel out. You are left with (5a+b)/2. This fraction cannot be simplified more.

To verify you can multiply (5a+b)/2 times (2a+14b). If it is correct, it should come back out as 5a^2 + 36ab +7b^2

Step-by-step explanation:

First you divide 42 by 12 and get 3.5, then you multiply that by 36 and get you answer.

Answer:

Step-by-step explanation:

A and B are both equal (corresponding parts)

A = B

5x - 5 = 3x + 13               Add 5 to both sides

5x = 3x + 13 + 5              Combine

5x = 3x + 18                    Subtract 3x from both sides

5x - 3x = 18                     Combine

2x = 18                            Divide by 2

2x/2 = 18/2

x = 9            

Angle B

B = 3x + 13                      Let x = 9

B = 3*9 + 13

B = 27 + 13

Angle B = 40

Answer:

Since the $307 is the buying price of the store which makes it 100%. The store needs to make a profit from the refrigerator so it adds a +38% on the refrigerator making it a value of 138% of $307 which is 138/100 * $307 =$423.66 but we need it to the nearest dollar which will be rounded of to $424 since it passed the .5 mark

A triangle's angles have to equal to 180 degrees , so option B is not a triangle because it equals to 175

Answer:

A. Triangle? Yes. How do I know? Triangles add up to 180 degrees, and the angles measures add up to 180.

B. Triangle? No. How do I know? The angle measures only add up to 175 degrees, so it can’t be a triangle.

C. Triangle? Yes. How do I know? A triangle = 180 degrees and the angle measures add up to 180.

Every book is 17 centimeters tall/long.

A : If the board is the same length as 21 books, its length is 17 x 21 = 357 centimeters.

B : 357 centimeters = 3.57 meters

Since 3.57 > 3.5, the board is long enough.

The equations that can be used to determine the original price of the laptop are p (1 + 0.32) = $1,137.84 and $1,137.84 = 1.035p

Markup is when the price of an item is increased by a certain percentage. The cost of the laptop was increased by 32%.

The price of the laptop after the increase = p(1 + percentage increase)

p (1 + 0.32) = $1,137.84

$1,137.84 = 1.035p
