The probability of not choosing a black shirt is...? please explain!
Answer:
80% or 8/10.
Step-by-step explanation:
Assuming the shirts in the bottom right are the "black" shirts, there is ten total shirts (1 red, 4 blue, 2 green, 1 white, 2 black.) Out of the ten shirts, 8 are not black. This means that there is an 80% chance that you will select a shirt that is NOT black.

Which line(s) intersect the parabola y = x^2 − 3x + 4 at two points? Select all that apply. A. y = –3x + 2 B. y = –3x + 3 C. y = –3x + 5 D. y = –3x + 6
Answer:
C and D
Step-by-step explanation:
Equating the line A and the parabola, we get
-3x + 2 = x² - 3x + 4
0 = x² - 3x + 4 +3x - 2
0 = x² + 2
-2 = x²
which has no real solutions. Then, the line A and the parabola don't intersect each other.
Equating the line B and the parabola, we get
-3x + 3 = x² - 3x + 4
0 = x² - 3x + 4 + 3x - 3
0 = x² + 1
-1 = x²
which has no real solutions. Then, the line B and the parabola don't intersect each other.
Equating the line C and the parabola, we get
-3x + 5 = x² - 3x + 4
0 = x² - 3x + 4 + 3x - 5
0 = x² - 1
1 = x²
√1 = x
which has 2 solutions, x = 1 and x = -1. Then, the line C and the parabola intersect each other.
Equating the line D and the parabola, we get
-3x + 6 = x² - 3x + 4
0 = x² - 3x + 4 + 3x - 6
0 = x² - 2
2 = x²
√2 = x
which has 2 solutions, x ≈ 1.41 and x ≈ -1.41. Then, the line D and the parabola intersect each other.

Three ballet dancers are positioned on stage. Mia is straight behind Jane and
directly left of Christine. If Jane and Mia are 3 meters apart, and Christine and Jane
are 5 meters apart, what is the distance between Mia and Christine?
Answer:3 m
Step-by-step explanation:
Given
Mia is 3 m behind Jane
Mia is left to the Christine
Distance between Mia and Christine is 5 m
Thus they form a right angles triangle shown in fig
So we can write

An in-ground swimming pool is meters long, meters wide, and meters deep. The water-resistant paint needed for the pool costs $ per square meter. Step by step.
1. How many sides of the pool do you have to paint?
2. How much paint (in square meters) do you need to paint the pool?
3. How much will it cost to paint the pool?
4. How much water will the pool hold?
Answer:
Step-by-step explanation:
I'm going to assume you meant to put numbers in the question, but I will answer in terms of x, y, and z, for length, width, and depth, respectively.
1. You need to pain 4 walls as well as the floor, so 5 surfaces total.
2. This question is asking for the surface area of the pool. There is 1 floor, 2 long walls and 2 wide walls.
Surface Area = 2 (wide) + 2 (long) + 1 (floor)
= 2(x*z) + 2(y*z) + 1(x*y)
*remember to answer in meters squared*
3. Total Cost = (surface area) * (cost per square meter)
*remember this is in dollars*
4. This question is asking about the volume of the pool:
Volume = x*y*z

3x3 + 9x2 + 4x + 12
O A. (3.2 + 4)(x+4)
O B. (3x2+3)(x + 4)
O c. (3x2 + 4)(x+3)
O D. (3x + 3)(x+3)
Answer:
C. (3x^2+4)(x+3)
Step-by-step explanation:
3x^3+9x^2+4x+12
=(3x^3+9x^2)+(4x+12)
=3x^2(x+3)+4(x+3)
=(3x^2+4)(x+3)
Therefore, C. (3x^2+4)(x+3)
The correct factor of the polynomial is,
⇒ (x + 3) (3x² + 4)
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

⇒ (x + 3) (3x² + 4)
Thus, The correct factor of the polynomial is,
⇒ (x + 3) (3x² + 4)

Use conversions to solve the problem. Yesenia buys juice to make punch for all her friends. She buys 1 quart of juice and one eighth gallon of juice. How many cups of juice does she buy?
Answer:
The cups of juice that Yesenia buys are:
6 cups.Step-by-step explanation:
To solve this, you need to know the conversión below:
1 gallon = 16 cups.Now the paragraph mentions that Yesenia buys 1 quart of juice (that refers to a quart of gallon), then, having the conversion above we can operate with a rule of three:
1 gallon = 16 cups1/4 gallon = XSolving this we have:
(1/4 * 16)/1 = 4 cupsIn the first purchase, Yesenia actually buys 4 cups (that is the same to 1 quart of gallon), next she buys one eighth, then we operate again with the first conversion but using this new quantity:
1 gallon = 16 cups1/8 gallon = XSolving this we have:
(1/8 * 16)/1 = 2 cupsBy last, we add every purchase:
Number cups of juice purchased by Yesenia = 4 cups + 2 cups = 6 cups.

The 6 participants in a weight-loss class lost the following weights (in pounds) after three weeks of dieting.
0,1, 6, 1,5,5
Assuming that these weights constitute an entire population, find the standard deviation of the population. Round your answer to two decimal places.
Answer:
2.38
Step-by-step explanation:
To find the standard deviation, subtract the mean from each number given, square each outcome, add them all together, divide all of that by the number of outcomes, then square root the whole equation.
Doing this gets you to 2.380476143, rounding this to two decimal places gives 2.38

The base of the square pyramid shown has an area of 576 square units. If the slant height of the pyramid is 20 units, what is the height of the pyramid?
18 units
13.4 units
16 units
31.2 units
Answer:
Option C - 16 units
Step-by-step explanation:
Since the base is a square and it has an area of 576 sq.units, thus, if the side length of the base is x, then;
x² = 576
x = √576
x = 24
To get the height, we will divide this side length by 2 and use Pythagoreas Theorem.
Since, we are told that the pyramid has a slant height of 20 units,
So using pythagoras theorem, we can find the height of the pyramid as;
h² = 20² - (24/2)²
h² = 400 - 144
h² = 256
h = √256
h = 16 units

The five-number summary for the number of teams in each of Brad's fantasy football leagues is shown in the following table.
The five-number summary suggests that about 50% of Brad's fantasy football leagues have fewer than how many teams?
Choose 1 answer:
(Choice A)
4
(Choice B)
7
(Choice C)
10
(Choice D)
14
(Choice E)
18
Answer:
The correct option is (C) 10.
Step-by-step explanation:
The five-number summary for the number of teams in each of Brad's fantasy football leagues is as follows:
Minimum: 4
Q₁: 7
Median: 10
Q₃: 14
Maximum: 18
The minimum value is the smallest value in the data set.
The first quartile (Q₁) is the value that is less than 75% of the observations.
The median is the middle most value of the data set. It is the value that is less than 50% of the observations.
The third quartile (Q₃) is the value that is less than 25% of the observations.
And the maximum value is the largest value in the data set.
So, the five-number summary suggests that about 50% of Brad's fantasy football leagues have fewer than 10 teams.
Thus, the correct option is (C).

Answer:
I believe the answers are C, D, and E. Sorry if I am wrong.
Explanation:
The discriminant is
D = b^2 - 4ac
D = (-5)^2 - 4(3)(-1)
D = 25 + 12
D = 37
This means 37 is under the square root, and we know the answers are B and F due to this. Also note with these two answer choices, they are in the form [tex]\frac{-b \pm \sqrt{D}}{2a}[/tex] where...
a = 3, so 2a = 2*3 = 6b = -5, so -b = -(-5) = 5Choices A, C, D, and E can be eliminated as the discriminant for these is D = 13.

A 25 foot ladder is leaning against a building. The building is 20 feet high. How far away from the building is the bottom of the ladder
Answer:
15 ft
Step-by-step explanation: To solve this, you have to use the Pythagorean Theorem. The 25 ft is the hypotenuse, the longest side of the triangle. the building's height, 20 ft is one of the legs. The missing measurement is one of the other legs.
Pythagorean Theorem: A^2 + B^2 = C^2
A and B are legs and C is the hypotenuse.
Substitute the values:
20^2 + B^2 = 25^2
400+ B^2 = 625
625 - 400 = 225
225 = 15^2
What is the solution to the equation = 3?
x = 1
x = 3
x = 9
x = 27
Multiply both sides by 9.
x/9 = 3
(x/9) * (9) = (3) * (9)
x=27
The solution of the expression x/9 = 3 is,
⇒ x = 27
What is Multiplication?To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.
We have to given that;
The expression is,
⇒ x/9 = 3
Now, Simplify the expression as;
⇒ x/9 = 3
Multiply by 9, we get;
⇒ 9 × x/9 = 9 × 3
⇒ x = 27
Thus, The solution is,
⇒ x = 27
