Answer:
y = 7x
Step-by-step explanation:
Complete question:
Find an equation for the line with the given properties. Parallel to the line 7x - y = -7; containing the point (0,0)
The equation of a line in point-slope form is expressed as;
y - y0 = m(x-x0)
(x0, y0) = (0,0)
Given the equation of the line as 7x - y = -7;
Rewrite and get the slope
-y = -7x - 7
y = 7x+7
Get the slope
mx = 7x
m = 7
Substitute into the equation
y - 0 = 7(x - 0)
y = 7x
Hence the required equation is y = 7x

For each of the following situations, state the predictor variable and the outcome variable.
a. A study is done to determine if elderly drivers are involved in more motor vehicle fatalities than other drivers. The number of fatalities per 100,000 drivers is compared to the age of drivers.
b. A study is done to determine if the weekly grocery bill changes based on the number of family members.
Answer:
Part a
Predictor variable - age of drivers
Outcome variable - number of fatalities caused by elderly drivers out of total 100,000 drivers
Part b
Predictor variable - Number of family members
Outcome variable - weekly grocery bill
Step-by-step explanation:
Part a)
Predictor variable is basically independent variable whose influence is studied on the dependent variable or the outcome variable
Predictor variable - age of drivers
Outcome variable - number of fatalities caused by elderly drivers out of total 100,000 drivers
Part b
Predictor variable - Number of family members
Outcome variable - weekly grocery bill
Which expression is equivalent to 60 Σ n=1 (2n − 1)2 ? Check all that apply.
9514 1404 393
Answer:
B, D
Step-by-step explanation:
The quadratic expands to ...
(2n -1)² = (2n)² +2(2n)(-1) +(-1)² = 4n² -4n +1
The coefficients can be factored out of the sum, so ...
∑(4n²) = 4∑n² for example
The sum of 60 ones is 60:
[tex]\displaystyle\sum_{n=1}^{60}{1}=1+1+1+\dots+1=60[/tex]
So, the sum can be written as ...
[tex]\displaystyle\sum_{n=1}^{60}{(2n-1)^2}\\\\=\boxed{4\sum_{n=1}^{60}{n^2}-4\sum_{n=1}^{60}{n}+\sum_{n=1}^{60}{1}}\\\\=\boxed{4\sum_{n=1}^{60}{n^2}-4\sum_{n=1}^{60}{n}+60}[/tex]

2(x + 4)2 = 20 solve by square roots
Answer:
x = − 4 ± √ 10,
Step-by-step explanation:
2(x + 4)² = 20
=> 2(x + 4) (x + 4) = 20
=> 2x + 8 (x + 4) = 20
=> 2x² + 8x + 8x + 32 = 20
=> 2x² + 16x + 32 = 20
=> 2x² + 16x + 12 = 0
=> Now solve using the quadratic formula:
x = − 4 ± √ 10,
Radical form: − 4 ± √ 10,
Decimal form: -0.84, -7.16
Hope this helps!

what does y intercept mean ?
Answer: The vertical line on a graph representing the vertical coordinate points.
Answer:
In analytic geometry, using the common convention that the horizontal axis represents a variable x and the vertical axis represents a variable y, a y-intercept or vertical intercept is a point where the graph of a function or relation intersects the y-axis of the coordinate system. As such, these points satisfy x = 0. Hope this helps.
Step-by-step explanation:
Before agreeing to purchase a large order of polyethylene sheaths for a particular type of high-pressure, oil-filled submarine power cable, a company wants to see conclusive evidence that the population standard deviation of sheath thickness is less than .05 mm. What hypotheses should be tested, and why
Answer:
H0 : σ = 0.5
H0 : σ < 0.5
Step-by-step explanation:
From the scenario described above, the company wants to see conclusive evidence that the population standard deviation of sheath thickness is less than .05 mm ; THIS SIMPLY means ; REJECTION OF the NULL HYPOTHESIS. This is because once there is a significant or conclusive evidence in hypothesis testing, then we reject the null and support the claim of the alternative hypothesis.
Hence, the alternative hypothesis is ; population standard deviation of sheath Thickness is less than 0.5.
H1 : σ < 0.5 ;
Therefore, our null will be ;
H0 : σ = 0.5

Answer:
14.4 m
Step-by-step explanation:
From the question given above, the following data were obtained:
Hypothenus = 36 m
Height of building (H) = 33 m
Length of shadow (L) =?
The length of the shadow can be obtained as follow:
Hypothenus² = H² + L²
36² = 33² + L²
1296 = 1089 + L²
Collect like terms
1296 – 1089 = L²
207 = L²
Take the square root of both side
L = √207
L = 14.4 m
Therefore, the length of the shadow is 14.4 m

Step-by-step explanation:
Answer:
E and F
Step-by-step explanation:
So, our inequalityis that the square root of x is eithr greater than or equal to 25.
Lets think of this as a equation, and try solving for x:
[tex]\sqrt{x} \geq 25[/tex]
Lets square both sides to get x normal:
[tex]x\geq 625[/tex]
Now, x must either be greater than or equal to this value.
Lets look at the answers:
125
-625
-5
5
700
625
Well, most these answers are below the 625.
However, some of these values look like they may be right:
-625
700
625
So, -625 cannot be it. Although it seems to be equal to to 625 above, its negative. This means its much smaller than it
We also have 625 and 700
700 is greater than 625, so that has to be an answer.
Remember that its greater than or equal to.
625 is equal to 625, so this is an answer as well.
Answers:
625 and 700
Hope this helps! Sorry that you could not get a real answer until now :(

Answer:
C. The rudely disagrees condition has a mean of 4.16 and a standard deviation of 0.85 while the politely disagrees condition has a mean of 3.82 and standard deviation of 0.97
Step-by-step explanation:
The given data is
x` Std. Dev
R. disagrees 4.16 0.854
P. disagrees 3.82 0.967
From this data we see that the R. disagrees has a mean of 4.16 and standard deviation of 0.854
while
the P. disagrees has a mean of 3.82 and standard deviation of 0.967.
Same figures are given only in option C because
Rounding 0.854 gives 0.85
Rounding 0.967 gives 0.97
So only option C is the best choice.
C. The R. Disagrees condition has a mean of 4.16 and a standard deviation of 0.85 while the P. Disagrees condition has a mean of 3.82 and standard deviation of 0.97

Ben and Jane have been approved for a $220,000 loan, 30-year mortgage with an APR of 3.82%. What will be their total interest for the 30 years?
The total interest on the loan will be $457,412,82892.
What is a mathematical equation and expression?A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.A mathematical equation is used to equate two expressions.Given is that Ben and Jane have been approved for a $220,000 loan, 30 - year mortgage with an APR of 3.82%.
We can find the total interest on loan, using the formula -
I = {P(1 + APR/100)^t − P}
The principal amount of loan = $220,000
Compound APR = 3.82%
Time = 30 years
Using the formula, we get -
220,000[1 + 0.0382]^30−220,000
220000{[1 + 0.0382]^30 - 1}
$457,412,82892
Therefore, the total interest on the loan will be $457,412,82892.
