Answer:

A

Step-by-step explanation:

A constant line looks like a flat line with a slope of 0.

The segment that shows a constant function is segment A.

Option A is the correct answer.

A function has an input and an output.

A function can be one-to-one or onto one.

It simply indicated the relationships between the input and the output.

Example:

f(x) = 2x + 1

f(1) = 2 + 1 = 3

f(2) = 2 x 2 + 1 = 4 + 1 = 5

The outputs of the functions are 3 and 5

The inputs of the function are 1 and 2.

A function is constant if the graph is a straight line.

So,

From the given graph, we see that line A is a straight line.

This means,

Segment A shows a constant function.

Thus,

The segment that shows a constant function is segment A.

Answer: 5 3/4

Step-by-step explanation:

Answer:

Step-by-step explanation:

So, first lets the probability of just finding a yellow marble. There are 9+5+2+4 marbles in total, and that is 19 marbles.

5 out of those 20 are yellow, so the probabilty is 5/20 which is 1/4 or 20%

Then, lets do just finding the probability of a color that isn't blue.

Out of 20 marbles, 11 are color not blue, and 9 are.

So that probability is 11/20

Now, I think we need to do 11/20-5/20 so 6/20=3/10

Im so sorry, I might be wrong. I found both probabilities but I dont know if my final step is right.

  2.  K'(-1, -5)

  3.  (-3, 5), (3, 10), (-6, 8); translation left 2 and up 7

Step-by-step explanation:

2. The transformation is the one you have shown:

  (x, y) ⇒ (x, -y) . . . . reflection over the x-axis

You are given the coordinates for K and asked for K', the reflected point. Use the x- and y-values in the transformation formula:

  K(-1, 5) ⇒ K'(-1, -5) . . . . . . the y-coordinate is negated

It's that simple.

__

3. Same deal, different formula.

  (x, y) ⇒ (x -2, y +7)

  A(-1, -2) ⇒ A'(-1-2, -2+7) = A'(-3, 5)

  B(5, 3) ⇒ B'(5 -2, 3 +7) = B'(3, 10)

  C(-4, 1) ⇒ C'(-4 -2, 1 +7) = C'(-6, 8)

When constants are added to the coordinates, the transformation is a translation.

The x-values are decreased by 2, so that is a shift left by 2 units.

The y-values are increased by 7, so that is a shift up by 7 units.

The attachment shows the translated triangle (red). The translation vector (-2, 7) is shown as a black arrow. You will notice each triangle vertex is translated that length in that direction.

Answer:

2. [tex]\displaystyle 64\:feet[/tex]

1. [tex]\displaystyle 5\:seconds[/tex]

Step-by-step explanation:

2. Sinse we do not have a y-intercept [C-value in this case], we have to use a part of the quadratic formula to solve for x, and rewrite this equation in Vertex Form, with [tex]\displaystyle [h, k][/tex] as the vertex point. Observe:

[tex]\displaystyle -\frac{b}{2a} = x \\ \\ -\frac{64}{2[-16]} = \frac{-64}{-32} = 2[/tex]

Now, keep in mind that [tex]\displaystyle -h[/tex] in the vertex formula, [tex]\displaystyle y = a[x - h]^2 + k,[/tex] gives you the OPPOSITE TERMS OF WHAT THEY REALLY ARE, so in this case, sinse 2 is already positive, you do not need to alter its operation sign. With this being stated, you should already have this:

[tex]\displaystyle y = -16[x - 2]^2[/tex]

Now, to find k, all you have to do is plug 2 into the TOP equation to get your maximum height:

[tex]\displaystyle -16[2]^2 + 64[2] = -16[4] + 128 = -64 + 128 = 64 \\ \\ \\ y = -16[x - 2]^2 + 64[/tex]

Therefore, sinse 64 is your k-value, 64 feet is indeed your maximum height.

1. Simply factour the quadratic equation:

[tex]\displaystyle y = -18x^2 + 90x \\ 0 = -18x[x - 5] \\ \\ 5, 0 = x[/tex]

In this case, from a height of sixty-four feet, it is IMPOSSIBLE for the football to hit the ground in zero seconds, therefore the ball will reach the ground in 5 seconds, which makes alot more sence.

I am joyous to assist you at any time.

Answer:

The margin of error for a 95% confidence interval is of 2.18 hours.

Step-by-step explanation:

The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So

df = 100 - 1 = 99

95% confidence interval

Now, we have to find a value of T, which is found looking at the t table, with 99 degrees of freedom(y-axis) and a confidence level of [tex]1 - \frac{1 - 0.95}{2} = 0.975[/tex]. So we have T = 1.984

The margin of error is:

[tex]M = T\frac{s}{\sqrt{n}}[/tex]

In which s is the standard deviation of the sample(square root of the variance) and n is the size of the sample.

In this question:

[tex]s = 11.5, n = 100[/tex]. So

[tex]M = T\frac{s}{\sqrt{n}}[/tex]

[tex]M = 1.984\frac{11}{\sqrt{100}}[/tex]

[tex]M = 2.18[/tex]

The margin of error for a 95% confidence interval is of 2.18 hours.

Answer:

The median is 16.

Step-by-step explanation:

To find the median of a set, first we sort the set in an incresing way. So

3,5,8,11,15,16,18,22,23,32,36

The set has 11 elements, so the median will be element at the position (11+1)/2 = 6, that is, the 6th element of the sorted set.

In this case, the median is 16.

Answer:

If Kareem were to work for 5 hours, she would get paid $45.

Step-by-step explanation:

If she gets paid $72 for working 8 hours, you would need to find how much she gets paid per hour by doing [tex]72/8[/tex].

Which then gives you $9 per hour, so then all you need to do is multiply $9 by the number of hours which in this case is 5 to get the answer of $45.

Answer:

7% does not represent the part 0.7 of the push-ups Malik completes because 7% is NOT equivalent to 0.7.

Step-by-step explanation:

Given that Malik completes 0.7 of the total number of push-ups his coach requires.

Checking the given options:

7% = 7/100 = 0.07

14/20 = 0.7

70% = 70/100 = 7/10 = 0.7

0.70 = 0.7

Therefore,

7% does not represent the part 0.7 of the push-ups Malik completes because 7% is NOT equivalent to 0.7.
