What is the equation of a line that has a slope of 2 and passes through point (-6,3)?
Answer:
The answer is
[tex] \huge y = 2x + 15[/tex]
Step-by-step explanation:
To find an equation of a line when given the slope and a point we use the formula
[tex]y - y_1 = m(x - x_1)[/tex]
From the question we have
[tex]y - 3 = 2(x + 6) \\ y - 3 = 2x + 12 \\ y = 2x + 12 + 3[/tex]
We have the final answer as
[tex]y = 2x + 15[/tex]

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.
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.

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

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 plumber charges $25 per hour on weekdays and $40 per hour on weekends. The plumber billed a total of 190 hours, worth a total of $5275. Let x represent the number of weekend hours worked, and write algebraic expressions for each of parts a-c below
Step-by-step explanation:
if x is the amount of weekend hours, let y be the amount of weekday hours. then you can solve for x by using the equations x + y = 190 and 49x + 25y = 5275. once you have values for x and y, the other answers should be easy

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

Step-by-step explanation: C= -14/3 which is simplified to -4 2/3
Answer:
A.
Step-by-step explanation:
So you foil 2c and -5
Which will give you 5c+4=2c-10
Subtract 2c 5c-2c+4=2c-2c-10
Then You will get3c+4=−10
Step 3: Subtract 4 from both sides.
3c+4−4=−10−4
3c=−14
Step 4: Divide both sides by 3.
3c/3=-14/3
So it will be -14/3 which is -42/3
Which is A.

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

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)
