Quotient=42

Step-by-step explanation:

Answer:

Step-by-step explanation:

y = a(x - p)² + q  - the vertex form of an equation of a parabola with a vertex (p, q)

(-2, 5)  ⇒  p = -2,   q = 5

y = a(x + 2)² + 5   - the vertex form of an equation of the parabola with vertex (-2, 5)

y-intercept of -27 means x=0,  y=-27

-27 = a(0 + 2)² + 5

-27 -5 = a(2)² + 5 -5

-32 = 4a

  a = -8

The equation of the parabola in vertex form that has a vertex (-2, 5) and y-intercept of -27:

                              f(x) = -8(x + 2)² + 5

Angle 2

Step-by-step explanation:

Vertical angles are angles facing each other, and have equal measures.

So if they gave you the measure of angle 2, you would’ve known the answer for angle three. ur welcome :)

Answer: Yea dude your best bet is 2

Step-by-step explanation: Because you really have to know your angles like obtuse and acute that type of stuff

Answer:

y = 20

Step-by-step explanation:

[tex]y : 28 = 5 : 7 \\ \\ \frac{y}{28} = \frac{5}{7} \\ \\ y = \frac{5 \times 28}{7} \\ \\ y = 5 \times 4 \\ \\ y = 20[/tex]

Answer:

Transitive Property

Step-by-step explanation:

Let's define the following word bank answer choices:

Complementary Angles  ⇒ Angles that add up to 90 degree

Vertical angles ⇒  pair of opposite angles formed by intersecting lines

Reflexive Property ⇒ equality states that a number is always equal to itself

Transitive Property ⇒ All real numbers x ,y, and z, if x=y and y=z , then x=z.

Solve:

Base on the given we know that it not complementary angles because it doesn't form 90 degree (right angle).

We Also know that it not vertical angles because it doesn't  shows angles opposite each other where two lines cross.

In addition, the given doesn't shows If a is a number, then. a = a. a=a.

Thus, Transitive Property is the answer.

One criterion that we can use to analyze patterns is to look at the difference between consecutive terms. With this, we will see that the missing number is 361.

For the first two we have:

11 - 10 = 1

for the second and third:

21 - 11 = 10

for the fourth and third:

32 - 21 = 11

for the fifth and fourth:

53 - 32 = 21

We already can see the pattern, the n-th term can be written as:

Aₙ = Aₙ₋₁  + Aₙ₋₂

This means that the missing number, the next one, will just be equal to the sum of the two previous ones.

Then the next number is:

N = 138 + 223 = 361

The arithmetic means are;

6.5 , 2.75, 4.125 , 4.8125

Step-by-step explanation:

We start by finding the mean of the two numbers;

(14-1)/2 = 13/2 = 6.5

Next;

(-1 + 6.5)/2 = 5.5/2 = 2.75

Next

(2.75 + 5.5)/2 = 4.125

Next;

(4.125 + 5.5)/2 = 4.8125

You subtract the lowest point from the highest point.

Lowest Point = 6 because the lowest y value the graph reaches is 6

Highest point is 12

12 - 6 = 6.

So since they are eating, they are taking away, or subtracting.

Answer:

20 - (4 + 2)

Step-by-step explanation:

The original amount is 20.

The number of cookies left is the original amount minus the amount that was eaten.

Amy ate 4 cookies.

Her brother ate 2 cookies.

Amount that was eaten: 4 + 2

Amount left = original amount - amount that was eaten

amount left = 20 - (4 + 2)

The approximately 99.7% of the bags will have lengths within 3 standard deviations.

We have given that the weights of 2-pound bags of best dog food are approximately normally distributed with a given mean and standard deviation.

The empirical rule for a normal distribution states that approximately all of the data falls within 3 standard deviations of the mean.

So the approximately 68% data falls within 1 standard deviation of the mean.

and the approximately 95% of data falls within 2 standard deviation of the mean.

Now the approximately 99.7% data falls within 3 standard deviation of the mean.

As the weights of 2-pound bags of best dog food are normally distributed,

Therefore, approximately 99.7% of the bags will have lengths within 3 standard deviations of the mean and option D is the correct choice.
