Answer:
If you draw a diagonal across the parallelogram from one vertex to the opposite vertex, you divide the parallelogram into two congruent triangles. Each triangle thus has 1/2 of the area of the parallelogram.

The function g(x) is a transformation of the quadratic parent function, f(x)
What function is g(x)?
Answer:
Option A.
Step-by-step explanation:
The parent function is the quadratic function, that is:
[tex]f(x) = x^2[/tex]
Function g:
The function g is the function f concave down, that is, -f.
Also, for the parent function, we have that y = 1 when x = 1. On the function g, otherwise, we have that when x = 1, y = -1/3. So:
[tex]g(x) = -\frac{1}{3}f(x) = -\frac{1}{3}x^2[/tex]
The correct answer is given by option A.
-3x^2
just did it and it’s correct. Your welcome <3
If f(x) = -3x - 5 and g(x) = 4x - 2, find (f+ g)(x).
O A. (f+ g)(x) = -x + 3
O B. (f+ g)(x) = x - 7
O c. (f+ g)(x) = -7x-3
O D. (f+ g)(x) = 7x - 7
Answer:
B
Step-by-step explanation:
you are just combining like terms since you are adding the equations together
(-3x-5) + (4x-2)
-3x + 4x = x
-5 + -2 = -7
so altogether
x -7

For a test in a math class, 60 students arrive and take out their supplies. Of those students, 22 bring pens, and 48 bring pencils. Only one student arrives without a pen or pencil.
How many students brought both a pen and a pencil?
Answer:
11 students brought both a pen and a pencil
Step-by-step explanation:
59 students brought a pen or pencil or both
48 + 22 = 70
70-59 = 11
11 students brought both a pen and a pencil

The amount that households pay service providers for access to the Internet varies quite a bit, but the mean monthly fee is $50 and the standard deviation is $20. The distribution is not Normal: many house- holds pay a low rate as part of a bundle with phone or television service, but some pay much more for Inter- net only or for faster connections.
A sample survey asks an SRS of 50 households with Internet access how much they pay. Let x be the mean amount paid.
(a) Explain why you can't determine the probability that the amount a randomly selected household pays for access to the Internet exceeds $55.
(b) What are the mean and standard deviation of the sampling distribution of ?
(c) What is the shape of the sampling distribution of x? Justify your answer.
(d) Find the probability that the average fee paid by the sample of households exceeds $55. television service, but some pay much more for Inter- net only or for faster connections.
Answer:
(a) See Explanation
(b) [tex]\bar x =50[/tex] and [tex]\sigma_x = 0.8944[/tex]
(c) The shape is normal
(d) [tex]P(\bar x > 55) = 0[/tex]
Step-by-step explanation:
Given
[tex]\mu = \$50[/tex] -- mean
[tex]\sigma = \$20[/tex] --- standard deviation
[tex]n=500[/tex] --- sample size
Solving (a): The reason we can't determine the probability that an amount to access internet by a household will exceed $55.
The question says that a lot of households pay low rates, but the percentage of the households in this category is not given. This means that it is impossible to determine the shape of the distribution.
Hence, the probability cannot be calculated.
Solving (b): Sample mean and Sample standard deviation
The sample mean estimates the population mean
So:
[tex]\bar x =\mu[/tex]
[tex]\bar x =50[/tex]
The sample standard deviation is calculated as thus:
[tex]\sigma_x = \frac{\sigma}{\sqrt n}[/tex]
[tex]\sigma_x = \frac{20}{\sqrt{500}}[/tex]
[tex]\sigma_x = \frac{20}{22.36}[/tex]
[tex]\sigma_x = 0.8944[/tex]
Solving (c): The shape of the distribution.
We have:
[tex]n = 500[/tex] --- The sample size
According to Central limit theorem, When the sample size is greater than 30, then the shape of the distribution is normal.
Hence, the shape is normal
Solving (d): [tex]P(\bar x \ge 55)[/tex]
Calculate the test statistic (t)
[tex]t = \frac{\bar x - \mu}{\sigma}[/tex]
[tex]t = \frac{55 - 50}{0.8945}[/tex]
[tex]t = \frac{5}{0.8945}[/tex]
[tex]t = 5.590[/tex]
So:
[tex]P(\bar x > 55) = P(t > 5.590)[/tex]
Referencing the z table, we have:
[tex]P(t > 5.590) = 0[/tex]
Hence:
[tex]P(\bar x > 55) = 0[/tex]

Answer:
A. g(x) = √(x -5), x ≥ 5
Step-by-step explanation:
You can use the definition of an inverse function to solve for g(x).
x = f(g(x))
x = (g(x))^2 +5
x -5 = (g(x))^2 . . . . . subtract 5
√(x -5) = g(x) . . . . . take the square root
The radical contents cannot be negative, so this is only defined for x-5 ≥ 0, or x ≥ 5.
g(x) = √(x -5), x ≥ 5
