Answer:
80% chance she will not be chosen
Step-by-step explanation:
the ratio of students picked would be 2:10 so there would be 8:10 students not chosen that is 80%. 20% chance she would be chosen.
I hope this is correct!
The probability that Aretha will not be chosen is 0.8.
What is the probability?Probability can be defined as the ratio of the number of favourable outcomes to the total number of outcomes of an event.
Given that, Aretha's teacher will choose two students from a class of 10 to prepare a display.
We know that, probability of an event = Number of favourable outcomes/Total number of outcomes
Probability of choosing 2students =2/10
Probability of not choosing students = 1-2/10
= 8/10
= 0.8
Therefore, the probability that Aretha will not be chosen is 0.8.

Manuel earns $7.25 per hour helping his neighbor. Last month he earned $348. Choose the correct equation and solution which determines the number of hours, h, Manuel worked.
Answer:
Number of hours= 48 hours
Step-by-step explanation:
Giving the following information:
Hourly rate= $7.25
Total earned= $348
To calculate the number of hours worked, we need to use the following formula:
Total earned= hourly rate*number of hours
number of hours= total earned / hourly rate
number of hours= 348 / 7.25
number of hours= 48 hours

A cylinder has a volume of 791.28 cubic centimeters. The height of the cylinder is 7.0 inches. Calculate the radius of the cylinder. Use 3.14 for π.
Answer:
The radius is 6
[tex] \sqrt{v \div \pi \times h =} [/tex]
=791.28/3.14×7.0
=
[tex] \sqrt{36} [/tex]
=6
The radius of cylinder is 3.764 cm.
What is volume?Each thing in three dimensions takes up some space. The volume of this area is what is being measured. The space occupied within an object's borders in three dimensions is referred to as its volume. It is sometimes referred to as the object's capacity.
Finding an object's volume can help us determine how much material is needed to fill it, such as how much water is needed to fill a bottle, aquarium, or water tank.
Given volume of cylinder = 791.28 cm³
height = 7.0 inches
so, 1 inch = 2.54 cm
7 inch = 2.54 x 7 = 17.78 cm
height = h = 17.78 cm
volume of cylinder = πr²h
where r = radius
V = πr²h
791.28 = 3.14(17.78)r²
r² = 791.28/55.8292
r² = 14.1732
r = √14.17732
r = 3.764 cm
Hence the radius is 3.764 cm.

easy algebra question below first correct answer gets brainliest
Answer:
x = 2 and -4
Step-by-step explanation:
(x + 1)² = 9
First, take the square root of both sides. This will eliminate the square on the left side.
(x + 1) = √9
Note that √9 can be 3 or -3.
Let's write out both possibilities.
(x + 1) = 3
(x + 1) = -3
Solve.
(x + 1) = 3
[subtract 1 from both sides]
x = 2
--
(x + 1) = -3
[subtract 1 from both sides]
x = -4
Your answers are 2 and -4.
Let's check our answers by plugging in the values back into the original equation.
(x + 1)² = 9
(2 + 1)² = 9
(3)² = 9
9 = 9
That solution is correct.
(x + 1)² = 9
(-4 + 1)² = 9
(-3)² = 9
9 = 9
That solution is also correct.
Your answer is correct.

Explanation:
(a) Keep in mind the meaning of the variables:
x = PS4 units soldy = X.box 1 units soldWith these definitions in mind, we can examine the constraints.
x ≥ 0 . . . . . we cannot sell a negative number of PS4 units
y ≥ 0 . . . . . we cannot sell a negative number of X.box 1 units
y ≥ 5 . . . . . we intend to sell at least 5 X.box 1 units
y ≤ 10 . . . . we cannot sell more than 10 X.box 1 units
x + y ≤ 10 . . . . . we can sell at most 10 units total
(Please note that the constraints y ≥ 0 and y ≤ 10 are redundant to other more restrictive conditions.)
__
(b) The objective function tells us the total profit:
P(x, y) = 100x + 80y
__
(c) Juan's goal: P(2, 7) = 100(2) +80(7) = 200 +560 = 760
Justin's goal: P(4, 5) = 100(4) +80(5) = 400 +400 = 800
Meeting Justin's goal would result in more profit.
__
(d) It is not possible to sell a negative number of units*, so negative values for the variables do not make any sense. (This is consistent with the x≥0, y≥0 constraints above.)

he levels of mercury in two different bodies of water are rising. In one body of water the initial measure of mercury is 0.05 parts per billion (ppb) and is rising at a rate of 0.1 ppb each year. In the second body of water the initial measure is 0.12 ppb and the rate of increase is 0.06 ppb each year.
Which equation can be used to find y, the year in which both bodies of water have the same amount of mercury?
0.05 – 0.1y = 0.12 – 0.06y
0.05y + 0.1 = 0.12y + 0.06
0.05 + 0.1y = 0.12 + 0.06y
0.05y – 0.1 = 0.12y – 0.06
