Answer:

Reflection over the y-axis and a translation down two units

Step-by-step explanation:

You can see that the corners of the triangle have been vertically reflected because of their orientation and then you have to think about what that would look like and decide what else was done to the object. With this, we can tell that the object moved down 2 units.

Answer:

Option (B)

Step-by-step explanation:

Since the linear graph is passing through the origin, there is a proportional relationship between the amount of chocolate (C) and amount of peanuts (P) used in the package of snacks mix,

P ∝ C

P = kC

k = [tex]\frac{P}{C}[/tex]

Here k = proportionality constant

Since, the given line passes through a point (3, 2),

k = [tex]\frac{2}{3}[/tex]

Therefore, ratio of chocolate and peanuts mixed is [tex]\frac{2}{3}[/tex].

Option (B) is the correct option.

Answer:

C) Prime

Step-by-step explanation:

x^2+12x-32

factor out the trinomial,

find two numbers that when they multiply,

you get the third term, which is -32,

when you add them,

you get the second term, which is 12.

Answer:

The length is 28 and the width is 11

Step-by-step explanation:

To solve this problem, we can make the width as x.

Since the length is 5 less than 3 times the width, it's going to be 3x - 5

So now we've got the length and width, just need to find the perimeter, which is all the sides added up together. They already gave us the perimeter, so we just have to solve the equation:

2(3x - 5) + 2x = 78

6x - 10 + 2x = 78

8x - 10 = 78

8x = 88

x = 11

x = 11, but remember, x is the width, not the length. Since we already found what x is, we just have to plug it into the equation of:

3x - 5

3 × 11 - 5

33 - 5 = 28

Answer: Length = 28 (don't forget to add the unit if there is one)

The best estimate of the average rate of change for the function graphed over the interval 1 ≤ x ≤ 3 is 3.

Average rate of change of a function is defined as the rate at which the value of the function is changing with respect to the change in the input values.

The interval given is 1 ≤ x ≤ 3.

The graph of the function is given below.

It can be clearly seen that,

The y value corresponding to x = 1 is y = f(1) = 2.

So one point on the graph is (1, 2).

The y value corresponding to x = 3 is y = f(3) = 8.

So the other point on the graph is (3, 8).

Average rate of change over 1 ≤ x ≤ 3 = [f(3) - f(1)] / [3 - 1]

                                                               = [8 - 2] / [2]

                                                               = 6/2

                                                               = 3

Hence the best estimate for the average rate of change of function over the interval 1 ≤ x ≤ 3 is 3.

I believe the answer is x=-2

Answer:

if ∠1 = 70°, then ∠5= 70°

Hence, option (A) is correct.

Step-by-step explanation:

Given

∠1 = 70°

To determine

We need to determine angle ∠5

From the diagram, it is clear that a transversal line crosses the two parallel lines, the angles in the matching corner would be corresponding angles.

As angle ∠5 is the corresponding angle of angle ∠1 = 70°.

Therefore,

if ∠1 = 70°, then ∠5= 70°

Hence, option (A) is correct.

Answer: x = -6

Step-by-step explanation:

Since 2 angles have to equal 180, you add both of the angles you see and figure out what that answer is

101+91=192

192 - x - x

192 - 6 - 6 = 180

Answer: x=-6

Step-by-step explanation:

They are supplementary angles so both measures = 180. So x+91+x+101=180. 2x+192=180. 2x=-12. X=-6

Answer:

9 times

Step-by-step explanation:

The pizza has 391 calories in it, and everytime you dip it into ranch, you add 7 calories to the 391.

454(calories in total) - 391(calories in the pizza)= 63

63 ÷ 7(calories everytime you dip into ranch) = 9

87,000,000

Step-by-step explanation:

The millionths place in 87,365,219 starts at 7.

87,365,219

The rhyme that I learned for this when I was younger was: 5 and above give it a shove, 4 or below, let it go.

The number 3 after the 7 is less than five so you would have to let it go. So, everything after 7 would become zeros and you would not round 7 up.

Your final answer becomes 87 million

Hope this helps! :)

After rounding 87,365,219 to the nearest million, the number is 87000000.

Focus on the digit in the next position to the right for rounding a number to the nearest million. If the number is 5, round up and if the number is 4 or less than 4, round down.

Consider the following figure.

The hundred thousand place number is 3 which is less than 4.

Thus, round down to 87000000.

Therefore, after rounding 87,365,219 to the nearest million, the number is 87000000.

The options are:

A. This was a biased sample. Jim should interview all in attendance.

B. This was a census. Any guest may have participated.

C. This was a random sample. It may not have included anyone in attendance.

D. This was a random sample. It may have included anyone in attendance.

A random sampling is simply referred to as a subset of individuals that are picked from a larger set of individuals.

With regards to the question, Jim wanted to find out what the audience thought about the debate and after the event, he stood at the exit to survey every fifth guest.

This means that it was a random sampling and anyone could have been picked, the sampling wasn't bias.
