Answer:
23
Step-by-step explanation:
First, we can rearrange the equation to make it look simpler.
2+y+11 ---->
y+2+11
Then, we can combine like terms, thus
y+13
Then, we can plug in 10 for y
(10)+13
Combine like terms again, and the answer is:

Question 17 (5 points) Find the equation of a line passing through the point (6,-5) and parallel to the line y = 7x + 1. Oy -*x+41 y=7x - 29 Oy = 7x - 47 47 X+ 7 Question 18 (5 points)
Answer:
y = 7x - 47
Step-by-step explanation:
y = mx + b (m is slope, b y-intercept)
Parallel lines have the same slope.
y - [tex]y_{1}[/tex] = m( x - [tex]x_{1}[/tex] )
~~~~~~~~~~~~~~~~
y = 7x + 1
m = 7
(6, - 5)
y + 5 = 7 (x - 6)
y = 7x - 47
A medical statistician wants to estimate the average weight loss of people who are on a new diet plan. In a preliminary study, he guesses that the standard deviation of the population of weight losses is about 10 pounds. How large a sample should he take to estimate the mean weight loss to within 2 pounds, with 90% confidence?
Answer:
68
Step-by-step explanation:
To get the sample size of the population, we will use the formula for calculating the standard error of the mean. This is expressed as;
SE = zσ/√n
z is the z score at 90% confidence
σ is the standard deviation
n is the sample size
SE is the mean weight loss
Given
z = 1.645
σ = 10
SE = 2
Required
sample size n
Substitute into the given equation;
SE = zσ/√n
2 = (1.645)(10)/√n
2 = 16.45/√n
√n = 16.45/2
√n = 8.225
n = (8.225)²
n = 67.650625
Hence the total sample should be about 68

Is x − 8 a factor of the function f(x) = −2x3 + 17x2 − 64? Explain. (2 points)
Answer:
x-8 is a factor of f(x)
Step-by-step explanation:
The polynomial remainder theorem states that the remainder of the division of a polynomial f(x) by (x-a) is equal to f(a).
We are given the function
[tex]f(x)=-2x^3+17x^2-64[/tex]
And it's required to find if x-8 is a factor of f.
Applying the mentioned theorem, we only have to find f(8):
[tex]f(8)=-2\cdot 8^3+17\cdot 8^2-64[/tex]
Operating:
[tex]f(8)=-2\cdot 512+17\cdot 64-64[/tex]
[tex]f(8)=-1024+1088-64[/tex]
[tex]f(8)=0[/tex]
Thus, x-8 is a factor of f(x)

How are x and y intercepts alike and different? ( I need like 3 reasons for each)
Answer:
x and y intercepts are alike because they're both on the graph ,they help you graph a line, they can be both found in the slope-intercept form equation
they're different one is when it can be found where it crosses the X line and one can be found where it's the y line, when is found at the end of the equation for slope intercept form and what is found near the slope. x-intercept is an input and y-intercept is an output
Miguel has a total of 27 dimes and nickels. The total value of the coins is $1.80. How many dimes and nickels does he have?
Answer:
There are 9 dimes and 18 nickels.
Step-by-step explanation:
Let d = be the number of dimes
n = be the number of nickels
d + n = 27...eq.1
0.10d + 0.05n = 1.80...eq.2
Solve the system of equations
d + n = 27
10d + 5n = 180 ( multiply eq.2 by 100 )
-5d - 5n = -135
5d = 45
d = 9 , there are 9 dimes so,0.90
n = 27 - 9 = 18, there are 18 nickels so, 0.90
To check: 9 dimes + 18 nickels = 27 coins
0.90 + 0.90 = $ 1.80 total value of the coins

Joanne can read around 16 sentences per minute of her current novel. She wants to finish her reading before the movie comes out next week. If she has 19 pages left to read and each page has about 140 sentences, how many hours should Joanne set aside to complete her reading? Show your work. Round the answer to the tenths place.
Answer:
The answer is "3 hours and 28 minutes".
Step-by-step explanation:
Calculating the total sentence:
[tex]= 19 \ pages \times 140 \ sentences \\\\= 2,660 sentences\\\\[/tex]
Calculating the minutes which is needed:
[tex]= 2,660 \div 16 \\\\ = 166.25 \ minutes\\\\[/tex]
Calculating the hours and minutes:
[tex]= 166.25 \div 60 \\\\=3 \ hours \ and \ 28 \ minutes[/tex]

4/12 can simplify to 1/3
Write an equation of the line that passes through the given point and is (a) parallel and (b) perpendicular to the given line.
Answer:
(a). y = 3x - 11 ; (b). y = [tex]-\frac{1}{3}[/tex] x - 1
Step-by-step explanation:
Parallel lines have the same slopes
Slopes of perpendicular lines are opposite reciprocals.
(3, - 2)
The slope of given line is 3
(a). Equation of ║ line is
y + 2 = 3(x - 3)
y = 3x - 11
(b). Slope of perpendicular line is [tex]-\frac{1}{3}[/tex]
y + 2 = [tex]-\frac{1}{3}[/tex] (x - 3)
y = [tex]-\frac{1}{3}[/tex] x - 1
The required equation of a line parallel to the line will be y = 3x - 7
The required equation of the perpendicular line is y = -1/3 - 7
Using the coordinate points to get the equation of the line (1, -4) and (2, -1)
The standard form of the equation is expressed as y = mx + b
m is the slope
b is the y-intercept
Get the slope:
m = y2-y1/x2-x1
m = -1+4/2-1
m = 3/1
m = 3
Get the y-intercept
-4 = 3(1) + b
b = -4-3
b = -7
The required equation of a line parallel to the line will be y = 3x - 7
For the equation of the line perpendicular, the slope of the line will be -1/3
The required equation of the perpendicular line is y = -1/3 - 7

Does the data in the table represent a function?
Please help guysssss
Answer:
No
Step-by-step explanation:
a function can not repeat
The table given in the problem does not represent a function.
What is a function?A function y = f(x) is a one to one relationship between two sets X and Y where the set X is called the domain and Y the range of function f(x) ans x ∈ X and y ∈ Y.
The ordered pair for data given in the table is as below,
{(2, 5), (3, 6), (4, 6), (5, 9), (8, 11)}
Suppose x denotes the first elements and y the second elements of the ordered pair.
Then, from the ordered pair it is concluded that for x = 3 and x = 4, the value of y is 6.
Which implies that the values of x are not unique for a given value of y.
Thus, it does not represent a function.
Hence, the given table does not represent a function as the values in the domain set are not unique.

When looking at the results of a 99% confidence interval, we can predict what the results of the two-sided significance test will be: Group of answer choices
Answer:
alpha=0.01
Step-by-step explanation:
confidence level = 1 - alpha
so alpha = 1 - confidence level = 1 - 0.99 = 0.01
In statistics, alpha represents the value that checks the test statistic in order to determine if it is significant or not. In other words, alpha is the acceptable margin of type 1 error. Alpha is also called the significance level, which opposes the confidence level. Significance level + confidence level = 1.

Completely factored form of t2 - 36
Answer:
( t + 6 ) ( t − 6 )
Step-by-step explanation:
t 2 − 36
since 36 is a square number, you'll have to unsquare it to get
t 2 − [tex]6^{2}[/tex]
Since both terms are perfect squares, factor using the difference of squares formula, a 2 − b 2 = ( a + b )( a − b ) where a = t and b = 6
You should get : ( t + 6 ) ( t − 6 ) !
