Answer: The mean is the average of all the values. The median is the number that falls in the exact center of all the measurements, while the mode is the number that occurs most frequently. ... One way to measure variability, range, is the difference between the highest and lowest values in a data set.

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.

Given that,
To determine the function whose curve is plotted in the graph.
The graph is a demonstration of curves that gives the relationship between the x and y-axis.
What are trigonometric equations?These are the equation that contains trigonometric operators such as sin, cos.. etc.. In algebraic operation.
Here,
Since the given graph is of cots because only cotx tends to infinity whenever x tends nπ where n is an integer on the number line.
Thus, the given graph shown in the image is y = cotx. Option D is correct.

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

PLEASE HELP.....................
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.

Answer:
I'm not sure if you still need it but the answer is the third one.
Step-by-step explanation:
In order for a line to be parallel the lines need to have the same slope.
Answer:
The answer would be y=3/4X+9
Step-by-step explanation:
It must have the same slope since it is parallel, so
m = 3/4
y - y1 = m(x - x1)
y - 0 = (3/4)[x - (-4)]
y = (3/4)(x + 4)
Suppose f(x) = x2. What is the graph of g(x)= 1/3f(x)
Answer:
Step-by-step explanation:
The graph of f(x) = x^2 is a parabola opening up and with vertex at (0, 0).
The graph of (1/3)f(x) is also a parabola that opens up and has vertex at (0, 0), but this new graph has been vertically compressed by a factor of 3.
The graph of g(x) = 1/3 f(x) is parabola. (as shown in the following image.)
What is the graph of a function?"The graph of a function f is the set of all points in the plane of the form (x, f(x))."
For given example,
f(x) = x²
The graph of a function f(x) would be a parabola with vertex at origin (0, 0).
And g(x) = 1/3 f(x)
⇒ g(x) = 1/3 (x²)
We know, the greater the quadratic coefficient, the narrower the parabola and the lesser the quadratic coefficient, the wider the parabola.
Since for a parabola g(x) the quadratic coefficient is 1/3.
This means the parabola g(x) is wider than the parabola f(x)
So, the graph of g(x) is the graph of f(x) scaled by 1/3 units.
The graph of g(x) is parabola (as shown in following figure)

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

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

Find the volume of a cylinder when the radius is 9 cm and the length is 20 cm
Answer:
5089.38 cm OR 1620π
Step-by-step explanation:
The formula for the volume of a cylinder is π[tex]r^{2}[/tex]h so if the radius is 9, 9 squared is 81. We multiply 81 by 20 and that gives us 1620. So in terms of pi, it is 1620π but if you just multiply it all together, it gives you 5089.38 cm. Please mark me brainliest and I hope this helped!
Based on the radius and the length of the cylinder, we can calculate that its volume is 5,091.43 cm³.
The volume of a cylinder can be calculated by the formula:
= π x radius² x height
Solving will give:
= π x 9² x 20
= π x 81 x 20
= 5,091.43 cm³
In conclusion, the volume is 5,091.43 cm³

2) slope = -4, y-intercept = 140
Step-by-step explanation:
to find the slope take rise over run, for y-intercept its always where ever the 0 falls on the x line.
1) since the rise(y) = 6, and the run(x) = 2, it becomes 6/2 making your answer 3. They y-intercept is x = 0, y = 1.
2) The rise(y) = -20, and the run(x) = 5, it becomes -20/5 making your answer -4. The y-intercept is x = 0, y = 140.

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.

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
