Please help me 15 points

Answer:

None are correct.

Step-by-step explanation:

10/30 wanted pepperoni, so 1/3 of them wanted pepperoni.

15/30 wanted cheese, so 1/2 wanted cheese.

5/30 wanted hamburgers, so 1/6 wanted hamburgers.

You can use this information to estimate the number of the 150 students who wanted each.

1/3 of 150 = an estimated 50 wants pepperoni

1/2 of 150 = an estimated 75 wants cheese

1/6 of 150 = an estimated 25 wants hamburgers

Now you can use this to see which one is true.

A. There are 40 students who want pepperoni

not true, there are 50

B. There are 100 students who want either pepperoni or hamburger

50(pepperoni) + 25(hamburger) = 75, so this is not true

C. There are 10 more students who will want cheese than hamburger

75(cheese) - 25 (hamburger) = 50, so this is not true.

D. There are 5 more students would want pepperoni than hamburger

50 (pepperoni) - 25 (hamburger) = 25, so this is not true

None of these answers are correct

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:

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:

3 inches is 150 and 1/2 is 25

Step-by-step explanation:

Answer:

100.3 units²

Step-by-step explanation:

Area of the figure = area of two semicircles + area of a parallelogram

= 2(½*πr²) + b*h

Where,

Radius (r) = ½ of 8 = 4

Base (b) = 10

Height (h) = 5

Plug in the values

Area of figure = 2(½*π*4²) + 10*5

= 16π + 50

Area = 100.265482

Area of figure = 100.3 units² (nearest tenth)

Answer:

Sample space S = {0,1,2,3,4,5}

Step-by-step explanation:

We all know that when a dice is tossed, the minimum value that can be obtained is 1 and the maximum value that can be obtained is 6.

Now, when two dice are tossed, the possible cases are:

[tex]= \left\{\begin{array}{cccccc}(1,1)&(1,2)&(1,3) &(1,4)&(1,5)&(1,6)\\(2,1)&(2,2)&(2,3) &(2,4)&(2,5)&(2,6)\\(3,1)&(3,2)&(3,3) &(3,4)&(3,5)&(3,6)\\(4,1)&(4,2)&(4,3) &(4,4)&(4,5)&(4,6)\\(5,1)&(5,2)&(5,3) &(5,4)&(5,5)&(5,6)\\(6,1)&(6,2)&(6,3) &(6,4)&(6,5)&(6,6)\end{array}\right\}[/tex]

However, the magnitude of the difference in no. of dots showing up in the two dice is:

[tex]= = \left\{\begin{array}{cccccc}(1,1)=0&(1,2)=1&(1,3)=2 &(1,4)=3&(1,5)=4&(1,6)=5\\(2,1)=1&(2,2)=0&(2,3)=1 &(2,4)=2&(2,5)=3&(2,6)=4\\(3,1)=2&(3,2)=1&(3,3)=0 &(3,4)=1&(3,5)=2&(3,6)=3\\(4,1)=3&(4,2)=2&(4,3)=1 &(4,4)=0&(4,5)=1&(4,6)=2\\(5,1)=4&(5,2)=3&(5,3)=2 &(5,4)=1&(5,5)=0&(5,6)=1\\(6,1)=5&(6,2)=4&(6,3)=3 &(6,4)=2&(6,5)=4&(6,6)=0\end{array}\right\}[/tex]

Thus, the sample space Sample space-related when two dice are tossed & the magnitude is:

S = {0,1,2,3,4,5,}
