Step-by-step explanation:
An apartment complex developer is considering building apartments in College Town, but first wants to do a market study. A sample was selected of monthly rent values ($) for 80 studio apartments in College Town with sample mean of 498.76. (Based on past experience, the developer assumes a known value of s = $65 for the population standard deviation.)
a. Develop a 98% confidence interval for the mean monthly rent for all studio apartments in this city.
b. Suppose the apartment developer wants a 98% confidence interval estimate of the population mean with a margin of error of E = $15. What sample size is needed?
Answers
Answer:
a. The 98% confidence interval for the mean monthly rent for all studio apartments in this city is between $481.85 and $515.67
b. A sample size of 102 is needed.
Step-by-step explanation:
Question a:
We have that to find our [tex]\alpha[/tex] level, that is the subtraction of 1 by the confidence interval divided by 2. So:
[tex]\alpha = \frac{1 - 0.98}{2} = 0.01[/tex]
Now, we have to find z in the Ztable as such z has a pvalue of [tex]1 - \alpha[/tex].
That is z with a pvalue of [tex]1 - 0.01 = 0.99[/tex], so Z = 2.327.
Now, find the margin of error M as such
[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]
In which [tex]\sigma[/tex] is the standard deviation of the population and n is the size of the sample.
[tex]M = 2.327\frac{65}{\sqrt{80}} = 16.91[/tex]
The lower end of the interval is the sample mean subtracted by M. So it is 498.76 - 16.91 = $481.85
The upper end of the interval is the sample mean added to M. So it is 498.76 + 16.91 = $515.67
The 98% confidence interval for the mean monthly rent for all studio apartments in this city is between $481.85 and $515.67
Question b:
This is n for which M = 15. So
[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]
[tex]15 = 2.327\frac{65}{\sqrt{n}}[/tex]
[tex]15\sqrt{n} = 2.327*65[/tex]
[tex]\sqrt{n} = \frac{2.327*65}{15}[/tex]
[tex](\sqrt{n})^2 = (\frac{2.327*65}{15})^2[/tex]
[tex]n = 101.68[/tex]
Rounding up:
A sample size of 102 is needed.

Step-by-step explanation:
First we need to find theother 2 angles of the triangle.
We are given that the top angle is 60°
We know that the angles of a triangle add up to 180°
To find the bottom left angle of the triangle...
We can see that it is alternate exterior angles so they will equal.
To find the third angle of the triangle...
180 - 60 (given angle) -53 (alternate exterior angle) = 67°
Now we know that the bottom right angle inside the triangle is 67°.
To find x...
subtract 67 from 180 because the like is a combination of x and the 67° angle we just found. (a straight line angle = 180°)
180 - 67 = 113

what is an equation of the line that passes through the points (4,-6) and has a slope of -3
1) y = -3x + 6
2)y = -3x - 6
3)y = -3x + 10
4) y = -3x + 14
Answers
Answer:
1) y = -3x + 6
Step-by-step explanation:
1) First, write the equation of the line in point-slope form with the given information. Use the point-slope formula [tex]y-y_1 = m (x-x_1)[/tex] and substitute values for [tex]m[/tex], [tex]x_1[/tex], and [tex]y_1[/tex].
Since [tex]m[/tex] represents the slope, substitute -3 in its place. Since [tex]x_1[/tex] and [tex]y_1[/tex] represent the x and y values of the point the line intersects, substitute the x and y values of (4,-6) into the formula as well. This gives the following equation:
[tex]y+6 = -3(x-4)[/tex]
2) Now, isolate the y in the equation to put it in slope-intercept form and find the answer.
[tex]y + 6 = -3(x-4)\\y + 6 = -3x+12\\y = -3x+6[/tex]
So, the first option is correct.

For simplify the work we can start to factorise all the possibles expressions:
2x + 8.
8 is multiple of 2, so it can became
2(x+4)
x^2 - 16 this is a difference of two squares, so it can be rewritten as:
(x+4)(x-4)
x^2 + 8x + 16
we have to find two numbers whose sum is 8 and whose product is 16
the two number are 4 and 4
it becames:
(x+4)(x+4)
x+ 4 can‘t be simplified
if we look at the expression, we can find that x-4 appears at the numerator so
x^2 - 16 must be at numerator
but the second factor (x+4) doesn’t appear, so has been simplified. This situation can be possible only in the D option
in fact
(x+4)(x-4)/2(x+4) * (x+4)/(x+4)(x+4)
it became
(x+4)(x-4)/2 * 1/(x+4)(x+4)

[tex](2x^3+4x^2-35x+15)\div (x-3)[/tex]
To find:
The quotient by using the synthetic division.
Solution:
We have,
[tex](2x^3+4x^2-35x+15)\div (x-3)[/tex]
Here,
Dividend = [tex](2x^3+4x^2-35x+15)[/tex]
Divisor = [tex]x-3[/tex]
The coefficient of dividend are [tex]2, 4, -35, 15[/tex]. Write the coefficients of the dividend on the top row and we need to use 3 as divisor for synthetic division. The synthetic division is show below:
[tex]3 | 2\quad \quad 4\quad \quad -35\quad \quad 15\\\quad{}\quad{} \quad \quad \ 6\quad \quad \ \ \ 30\quad -15\\\overline{\quad 2\quad \quad 10\quad \quad -5\quad \quad 0\ \ \ }[/tex]
The bottom row represents the coefficients of quotient but the last element of bottom row is the remainder.
Degree of dividend is 3 and degree of division is 1. So, the degree of quotient must be [tex]3-1=2[/tex].
The quotient is [tex]2x^2+10x-5[/tex] and the reminder is 0.
Therefore, the correct option is D.

Step-by-step explanation:
The value of x is 13, then the measure of angle ∠B will be 121 degrees. Then the correct option is D.
What is an angle?Angle is the space between the line or the surface that meets. And the angle is measured in degree. For complete 1 rotation, the angle is 360 degrees.
Linear angle - If the total of two angles is 180 degrees, they are said to be linear angles.
The angle ∠A and ∠B form a linear pair.
If ∠A = (6x – 19) and ∠B = (11x – 22).
Then we have
∠A + ∠B = 180°
(6x – 19) + (11x – 22) = 180
17x – 41 = 180
17x = 221
x = 13
The value of x is 13, then the measure of angle ∠B will be
∠B = (11 × 13 – 22)
∠B = 143 – 22
∠B = 121
