6y = 12
~Divide 6 to both sides
y = 2
Best of Luck!
Answer:
2.16
Step-by-step explanation:
6y - 5 = 7
7 + 5 = 13
6y = 13
6y/6 = 13/6
y = 2.16

For a certain urban area, in a random sample of 7 months, an average of 28 mail carriers were bitten by dogs each month. The standard deviation of the sample was 3.5. Find the 99% confidence interval of the true mean number of mail carriers who are bitten by dogs each month. Assume the variable is normally distribute.
a. (29.38)
b. (25, 33)
c. (23,33)
d. (23.35)
Answer:
C
Step-by-step explanation:
Mean = 28
S = 3.5
N = 7
We use the t distribution here.
Level of significance = 99%
Degree of freedom = 7-1 = 6
Using the t table at 99%, and df of 6
T' = t tabulated = 3.7
Confidence interval =[ (mean - t's)/√n , mean + t's)/√n]
= 28-3.7*3.5/√7 , 28+3.7*3.5/√7
= 23.11, 32.89
When approximated
= 23, 33 after rounding to the nearest integer
Therefore option c is the answer

“ Create two whole number division problems that have a quotient of 9 and a remainder of 5. Justify which is greater using decimal division”
Answer and equation: If we choose two whole numbers; 8 and 10
We want to divide certain numbers by 8 and 10 to get 9 remainder 5.
In this case; 77 divided by 8 is equal to 9 rem 5
and 95 divided by 10 is equal to 9 rem 5
To justify which is greater, we use decimal division;
= 77 divided by 8 we get 9.625 ( 77 ÷ 8 = 9.625)
and
= 95 divided by 10 is equal to 9.5 (95 ÷10 = 9.5)
Therefore; the first case is greater since 9.625 is greater than 9.5
That is; 9 rem 5 got after dividing 77 by 8 is greater than 9 rem 5 got after dividing 95 by 10.

How many degrees of freedom will the error have in a randomized block design with five treatments and three blocks?
a. 2.
b. It will depend on the total sample size.
c.4.
d. 8.
Answer:
A. 2Step-by-step explanation:
Degree of freedom is expressed according to the formula as shown;
Degree of freedom = Sample size (Treatments) - number of parameters(Block)
Given
Number of treatments = 5
Number of blocks = 3
Degree of freedom = 5 - 3
Degree of freedom = 2
Hence the error will have 2 degrees of freedom in the randomized block design.

At which point do the equations y=−2x+10 and y=x+4 intersect?(1 point)
(1,6)
(2,6)
(2,5)
(1,5)

(1 point)
Their intersection point is the only point where different inputs into both functions yield different outputs.
Their intersection point is the only point where the same input into both functions yields different outputs.

Answer:
2,6
Step-by-step explanation:
Answer:
1. (2,6)
2. C
3. B
Step-by-step explanation:
y = - 2x + 10
y = x + 4
SInce the two equation both equal y, we can said they are equal.
- 2x + 10 = x + 4
- 10 - 10
- 2x = x - 6
- x - x
- 3x = - 6
/-3 /-3
x = 2
Then we plug the x value into the equations and we will get the point that intersects y=-2x+10 and y=x+4.
- 2(2) + 10 = 2 + 4
- 4 + 10 = 6
6 = 6
This is true since both sides are equal.
The point that intersects y=-2x+10 and y=x+4 is (2,6).
2. If the two lines y1=−12x+5 and y2=2x+5 were to be graphed, what would their intersection point represent?
C) Their intersection point is the only point where different inputs into both functions yield the same output.
Ex: y=-2x+10 and y=x+4 both have the same solution which is (2,6).
3. Given an equation y=−13x+5, explain the steps for using slope-intercept form to graph this equation.
y = - 1/3x + 5
y = - 1/3(0) + 5
y = 5
Point: (0,5)
Slope: - 1/3
Rise over run (y/x) so up 3 and left 1.
B) Use the y-intercept to plot the point (0,5). Then, using the y-intercept as a reference point, move left 1 unit and up 3 units, and plot a second point.

The number of daily sales of a product was found to be given by S = 600xe−x2 + 600 x days after the start of an advertising campaign for this product. (Round your answers to one decimal place.) (a) Find the average daily sales during the first 30 days of the campaign—that is, from x = 0 to x = 30. (b) If no new advertising campaign is begun, what is the average number of sales per day for the next 20 days (from x = 30 to x = 50)?
Answer:
a. 20520
b. 12600
Step-by-step explanation:
Given the function S = 600xe^-x² + 600.
a. To find the average, we have to find the definite integral of the function because average, as it is known, is the sum of data points divided by the size of its dataset, this can be used for discrete data. Integral formula is just the continuous form of average, so we are using integral because we were given an interval of x= 0 to X = 30.
Let's integrate 100xe^x² first. Let –x² = u, this means –2xdx = du and we have dx = –du/2x. Also, when x = 0, u = –(0)² = –0 and when x = 30, u = –(30)² = –900. When we make our substitutions we have:
–600(xe^udu)/2x = –600(e^udu)/2 upon integrating that we have –600(e^u)/2. Applying our interval we have
–600[(e^900)/2 – (e^0)/2] ≈ – [– 3.7 – (1/2)] = –600 (–4.2) = 600 x 4.2 = 2520
Now let's integrate 600, with the interval x = 0 to x = 30 (we are using this interval here because the substitution we made didn't affect this).
We have, upon integrating:
600x.
Substituting our intervals we have:
600(30 – 0) = 600 x 30 = 18000.
Adding that up we have: 2520 + 18000 = 20520.
b. The same method is needed, just difference of interval.
Therefore, after integrating the first component with intervals u = 900 to u = 2500 (from x² = u) we have:
–600[(e^2500)/2 – (e^900)/2] ≈ –600[2.7 – 3.7] = –600(–1) = 600.
Then for the second component:
600x using x = 30 to x = 50
600(50 – 30) = 600 x 20 = 12000.
Adding that up we have:
12000 + 600 = 12600.

Answer: -4
Step-by-step explanation:
so first off, we evaluate this whole mess.
(4+l-12l/6)^2 / -9
then, we divide it.
(4+12/6)^2 / -9
now, we calculate it.
(4+2)^2 / -9
then, we evaluate it.
6^2 / -9
we then reduce the fraction.
36 / -9
solution: -4
