What is an equation of the line that passes through the point (-1,-7) and is perpendicular to the line x+y=6x

Answer:

From the question we are told to test if the difference in the sample proportions statistically significant and given that the sample size is sufficiently large i.e  [tex]n_ 1 \ and \ n_2 \ is \ > \ 30[/tex] then the most appropriate test to use is  the

          Two samples z test

Step-by-step explanation:

Answer:

Step-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.

Answer:

there are 12 boys because 32/8 =4 and the ratiots 3 to 8 which means you need to multiply 3 by 4 which gives you 12

Step-by-step explanation:

Answer:

44 members

Step-by-step explanation:

Because to find out the number of members first you have to find out the number of boys in choir

Divide total number of girls (32) by ratio number (8) and you get 4

Multiply the 4 you got by the ratio of boys (3), you get 12 when you multiply these together

Add the total number of boys in choir (12) and number of girls (32) and you get 44 members!

Good day to you and I hope you like my explination.

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.

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.

Step-by-step explanation:

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

Answer:

Students understand the value of a ratio A: B is A/B. ... If two ratios are equivalent, they have the same value. Grade 6, Module 1, Lesson 8: Classwork. Recall that when given a ratio A: B, where B ≠ 0, we call the quotient, A/B, the value of the ratio.

Step-by-step explanation:

For example, the most common way to write a ratio is as a fraction, 3/6. We could also write it using the word "to," as "3 to 6." Finally, we could write this ratio using a colon between the two numbers, 3:6. Be sure you understand that these are all ways to write the same number.

Step-by-step explanation:

To find the formula for the nth term ,

First , find the common difference or common ratio.

Common difference =

[tex]T_2-T_1 \\ - 2 - 3 \\ = - 5[/tex]

Common ratio =

[tex]T_2/T_1 \\ \frac{ - 2}{3} [/tex]

The common difference applies to the other given numbers for example :

[tex]T_3- T_2 = - 7 - ( - 2) \\ = - 7 + 2 = - 5[/tex]

this proves that it is an arithmetic sequence and the given formula for the nth term of an arithmetic sequence is

T_n =a(n-1)d

Where n = no of terms

a= first term

d= common difference

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.

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
