Step-by-step explanation:
the slope for this equation is 7
Hii!
__________________________________________________________
Answer:
Exactly the same as the slope of this line, which is 7! ^^
Step-by-step explanation:
Like I said above, the slope is the same.
This I concluded because the slopes of parallel lines are equal to each other,
∴, the slope of a line that is parallel to y=7x+5 is also 7.
Which is reasonable. Remember, parallel lines never intercept each other.
If two lines have different slopes, and they're next to each other (for instance, on a co-ordinate plane), they will intercept each other, someday...
Lines like this:
_______________________________________________________
________________________________________________________
Have the same slope, and they'll never intercept.

A report states that the mean yearly salary offer for students graduating with a degree in accounting is $48,734. Suppose that a random sample of 50 accounting graduates at a large university who received job offers resulted in a mean offer of $49,830 and a standard deviation of $3600. Do the sample data provide strong support for the claim that the mean salary offer for accounting graduates of this university is higher than the national average of $48,734
Solution :
To claim to be tested is whether "the mean salary is higher than 48,734".
i.e. μ > 48,734
Therefore the null and the alternative hypothesis are
[tex]$H_0 : \mu = 48,734$[/tex]
and [tex]$H_1 : \mu > 48,734$[/tex]
Here, n = 50
[tex]$\bar x = 49,830$[/tex]
s = 3600
We take , α = 0.05
The test statistics t is given by
[tex]$t=\frac{\bar x - \mu}{\frac{s}{\sqrt n}}$[/tex]
[tex]$t=\frac{49,830 - 48,734}{\frac{3600}{\sqrt 50}}$[/tex]
t = 2.15
Now the ">" sign in the [tex]$H_1$[/tex] sign indicates that the right tailed test
Now degree of freedom, df = n - 1
= 50 - 1
= 49
Therefore, the p value = 0.02
The observed p value is less than α = 0.05, therefore we reject [tex]$H_0$[/tex]. Hence the mean salary that the accounting graduates are offered from the university is more than the average salary of 48,734 dollar.
What’s (6n^2 - 4n + 6) +(n-2).!?
Answer (6n^2 - 4n + 6) +(n-2) =6n^2-3n+4
Step-by-step explanation:
Remove\:parentheses 6n^2-4n+6+n-2
{Group like terms} 6n^2-4n+n+6-2
Add similar elements: (6n^2-3n+6-
Add/Subtract the numbers: (6n^2-3n+4)
Which absolute value function, when graphed,
represents the parent function, fx) = x, reflected over
the x-axis?
O fx) =-x|
O f(x) =-x
O fx) = | +1
O f(x) = x-1|
Answer:f(x)=|+1
Step-by-step explanation:
The reflection of the parent absolute value function over the x-axis is:
f(x) = -|x|
How to reflect a function over the x-axis?
First, for a point (x, y), a reflection over the x-axis just changes the sign of the y-component, then the reflected point will be (x, -y).
For the case of a function, we have:
y = f(x).
Then if we reflect the function f(x) over the x-axis, we will get:
g(x) = -f(x).
In this case, we want to reflect the parent function |x| over the x-axis, so we will get:
f(x) = -|x|
So the correct option is the first one.

If a=15 and b=6, then 9a²-48ab+64b²=?
Answer:
9
Step-by-step explanation:

Value of 'b' = 6
Simplifying the expression given in question,

Serial numbers for a product are to be made using 4 letters followed by 4 digits. the letters are to be taken from the first 9 letters of the alphabet, with no repeats. the digits are to be taken from 0-9 with no repeats. How many serial numbers can be generated?
Answer:
15,240,960 numbers
Step-by-step explanation:
To solve this were going to use the principle of permutations. The formula for permutation is given as
P = n! / (n - r)!
Now, the question specifically stated that repeats aren't tolerated, thus for the needed number of serial numbers would be gotten by multiplying the permutation is 4 and 9, by that of the permutation of 4 and 10.
We then have something that is looking like this
Permutation of 4 and 9.
P = 9! / (9 - 4)!
P = 9! / 5!
P = 362,880 / 120
P = 3,024
Permutation of 4 and 10
P = 10! / (10 - 4)!
P = 10! / 6!
P = 3,628,800 / 720
P = 5,040
Multiplying both together would then fetch us our final answer
N = 5,040 * 3,024
N = 15,240,960

Each side length of a triangle is 4 cm. What type of figure is it ?
Acute
Scalene
Right
Equilateral
I need 2 answers
Answer:
Equilateral and acute
Explanation:
Equilateral triangles refer to triangles where all side lengths are equal. Acute triangles are triangles where all angles are acute (less than [tex]90^{\circ}[/tex]). Since each side length of the triangle is [tex]4cm[/tex], the triangle is an equilateral triangle. Due to the property of equilateral triangles where each angle is equivalent to [tex]60^{\circ}[/tex], we can conclude that this triangle is equilateral and acute.

If you have 1912 copies x 305 runs per copy. Would I estimate by multiplying 1912 copies per run by 305 runs.
I think it’s 1912 copies x 305.
Answer:
[tex]Total = 583160[/tex]
Step-by-step explanation:
Given
[tex]Copies = 1912[/tex]
[tex]Runs = 305[/tex] per copy
Required
Determine the total number of runs
To do this, we multiply the number of copies by the number of runs per copy.
i.e.
[tex]Total = Copies * Runs[/tex]
Substitute values for Copies and Runs
[tex]Total = 1912 * 305[/tex]
[tex]Total = 583160[/tex]
Hence, there are 583160 in total

Using a graphical method to determine if a set of ungrouped raw data is normally distributed, that data would be normally distributed if:________.a. The plot of the data was curvilinear
b. The data was randomly distributed
c. The plot of the data was linear
d. The plot of the data was significantly different from zero
Answer: c. The plot of the data was linear
Step-by-step explanation:
If a graphical approach is used to analyze a set of raw data group, if the data set is normally distributed it is linear that is it is (attached to each other), we can conclude that the data set is normally distributed because on the plotted graph the information appears linear.

Answer:
A. No, she will not complete the book in an hour.
B. It will take 24 more mins to finish the book.
Step-by-step explanation:
A. If it takes her 35 mins to read 20 pages, it takes her 7/4 mins to read one page (35/20 = 7/4). To read 48 pages, it'll take her 48*(7/4) = 84 mins, which is more than 60 mins.

if gage gets 35 bucks per month how much months will it take him to get 300 bucks
Answer:
at least 9 months
Step-by-step explanation:
35×9=315
Answer:
It will take Gage 9 months to get $300.
Step-by-step explanation:
Let [tex]m[/tex] = months.
The expression [tex]35m[/tex] will represent money per month, and must be greater than or equal to $300.
Set up your inequality:
[tex]300\leq 35m[/tex]
Divide both sides of the inequality by the coefficient of [tex]m[/tex]:
[tex]8.6=m[/tex]
Round to the nearest whole number:
[tex]9=m[/tex]
Therefore, it will take Gage 9 months to get $300.
-
Check your work by substituting the solved value into the initial inequality:
[tex]300\leq 35(9)[/tex]
[tex]300\leq 315[/tex]
Since $315 is greater than $300, our solution is correct.

A taco stand specializes in beef tacos. The food permit to run the stand costs $100. The cost of supplies to make each taco cost $0.50. The stand is selling tacos for $3.00 each.
The inequality 3n > 100 + 0.50n represents the sales required for the taco stand to make a profit.
Will the taco stand make a profit if it sells 50 tacos? Show how you know .
Answer:
Yes the stand would make a profit, a $25 profit to be exact.
Step-by-step explanation:
the equation is 3n>100+0.50n
if the stand sells 50 then n=50 making it 3(50)>100+0.50(50).
by doing the multiplication then adding you'll get 150>125 since 3×50 is 150 ans 0.50×50 is 25 and you add the 25 to 100.
which means it'll gain $150 and spend $125 on maintaining the stand and for supplies with a $25 left over. It would make a profit
