Answer:
150°
Step-by-step explanation:
We know each angle in a equilateral triangle is 60° and that of a rectangle is 90° . So ,
[tex]\implies \angle ABC = \angle DBC + \angle ABD \\\\\implies \angle ABC = 90^o + 60^o \\\\\implies \boxed{\boxed{ \angle ABC = 150^o }}[/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
Follow the steps for dividing decimals. Then, round to two decimal places (hundredths).

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.
Answers
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]

The function g(x) is a transformation of the quadratic parent function, f(x)
What function is g(x)?
Answers
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.

Which of the following graphs could be a representation of a geometric
sequence?
Answers
Answer:
Third one
Step-by-step explanation:
In geometric sequence, the graph must have one slope
The graphs could be a representation of a geometric
sequence are given by option (A), option (B) and option (D)
What is a geometric sequence?"It is a sequence in which the ratio between consecutive terms is equal."
For given question,
We need to identify the graphs that could be a representation of a geometric sequence.
A sequence [tex]a_1,a_2,...,a_n[/tex] is geometric sequence if [tex]\frac{a_2}{a_1}=r[/tex],
[tex]\frac{a_3}{a_2}=r[/tex],. . ., [tex]\frac{a_n}{a_{n-1}} = r[/tex]
This means, for geometric sequence the number being multiplied each time is constant.
And the geometric sequence is of the form
[tex]a_1,(a_1r),(a_1r^2),...[/tex]
If we graph the geometric sequence then it would be non-linear.
From above pattern of geometric sequence, we can say that the graph of the geometric sequence is exponential in nature.
Therefore, the graphs could be a representation of a geometric
sequence are given by option (A), option (B) and option (D)
