<h3>Answer: y = 9</h3>

====================================================

Explanation:

Locate 12 on the horizontal x axis number line.

Then move straight up until reaching the parabola.

Afterward, move to the left to arrive at y = 9 on the vertical y axis.

We predict the y value will be y = 9 for the input of x = 12.

Refer to the diagram below to see what's going on.

Belinda bought a car one year ago.

lesya692 [45]

Answer:

$16,500

Step-by-step explanation:

The computation of the amount that should be paid for the car is shown below:

Since the car would be purchased one year ago

And, the value of the car would be decreased by 15% to $14025

So the amount that should be paid is

= $14025 × 100 ÷ (100 - 0.15)

= $16,500

In a sociology class there are 1414 sociology majors and 1111 non-sociology majors. 33 students are randomly selected to present

saul85 [17]

Answer: $0.4065$

Step-by-step explanation:

Given : In a sociology class there are 14 sociology majors and 11 non-sociology majors.

Total students = 14+11=25

Number of students are randomly selected = 3

Then, the number of ways to select 3 students from 25 students :-

$^{25}C_3=\dfrac{25!}{(25-3)!3!}=\dfrac{25\times24\times23\times22!}{22!3!}\\\\=2300$

Number of ways to select at least 2 of the 3 students re non-sociology majors :-

$^{14}C_1\times^{11}C_2+^{14}C_0\times ^{11}C_{3}\\\\=(14)\times\dfrac{11!}{2!(11-2)!}+(1)\times\dfrac{11!}{3!(11-3)!}\\\\=(14)(11\times5)+\dfrac{11\times10\times9}{6}\\\\=770+165=935$

The probability that at least 2 of the 3 students selected are non-sociology majors will be :-

$\dfrac{935}{2300}=0.40652173913\approx0.4065$

A cell phone tower covers a circular area with a radius of 15 miles. You are at a location that is 11 miles west and 12 miles so

Murljashka [212]

Answer:

No you do not.

This is because we can use Pythagoras Theorem to show that our location sits outside the 15 mile radius of the cell tower.

To work is out you would write the equation

${11}^{2} + {12}^{2} = 265$

Then to work out the Hypotheses you would

$\sqrt{265} = 16.2788205961$

Which proves that the location is outside of the 15 Mile radius of the cell tower.

Step-by-step explanation:

1. A horizontal number line is shown with labels at negative 50, 0, and 35. A red arrow (labeled withdrew 50 dollars) begins at 0 and ends at negative 50. A blue arrow (labeled deposited 35 dollars) begins at 0 and ends at 35.

2. A horizontal number line is shown with labels at negative 50 and 0. A red arrow (labeled withdrew 50 dollars) begins at 0 and ends at negative 50. A blue arrow (labeled deposited 35 dollars) begins at negative 50 and ends at negative 15.

3. A horizontal number line is shown with labels at negative 35, 0, and 50. A blue arrow (labeled deposited 35 dollars) begins at negative 35 and ends at 0 A red arrow (labeled withdrew 50 dollars) begins at 50 and ends at 0.

4. A horizontal number line is shown with a label at 0. A blue arrow (labeled deposited 35 dollars) begins at 0 and ends at 35. A red arrow (labeled withdrew 50 dollars) begins at 35 and ends at negative 15.
