y=-2x+b

so now we plug in the coordinates

-3=(1)-2+b

-3=-2+b

-1=b

Answer:

33% or 4/12

Step-by-step explanation:

There are 5 red, 3 green, and 4 yellow, so make it into a fraction. In total there are 12 marbles(5+3+4). There are 4 yellow marbles, so the fraction would be 4/12. Turn this into a percent to get the probability. 4/12 = 0.33 = 33%

Answer:

Yes, Logan's pay rates are proportional for those 2 days.

Step-by-step explanation:

First, we have to figure out what 6 divided by 3 is.

6 ÷ 3 = 2

So, now we have to divide 90 by 45.

90 ÷ 45 = 2.

So, yes it is proportional because 6 ÷ 3 = 2 and 90 ÷ 45 is also 2 so yes it is proportional.

Answer:

trial A percent error is 20%. trial B percent error is 18.75%

trial A had the greater percent error.

9514 1404 393

Answer:

Step-by-step explanation:

The absolute error is the difference between the estimate and the actual weight:

  7.0 kg -6.6 kg = 0.4 kg . . . . absolute error

__

The relative error is the ratio of the absolute error to the actual weight:

  (0.4 kg)/(6.6 kg) × 100% = 6.060606...% ≈ 6.1% . . . . relative error

Answer:

Solve for z- by simplifying both sides of the inequality, then isolating the variable.

Inequality Form:

z≥−14.4

Step-by-step explanation:

The solution of the inequality −8 ≤ z + 6.4 is z ≥ 14.4.

A closed circle on a point represents including(less than or equal to or greater than or equal to) the point and an open circle on a point represents we are not including(strictly less than or greater than) that point.

The solution of the inequality −8 ≤ z + 6.4 is,

z ≥ 6.4 + 8.

z ≥ 14.4.

∴ The graph of the inequality z ≥ 14.4 will be a line denoted by a closed circle at 14.4 to infinity or a region greater than or equal to 14.4.

Answer: yes they both have the same answer.

Step-by-step explanation: 12 - 7 equals 4 and 28/7 equals 4

Answer:

yes x is the same in both problems

Step-by-step explanation:

in the first one you subtract seven from both side to leave you with x=5

in the second problem you subtract 14 (2x=10) from both sides then divide both sides by 2 so you are left with x=5

Answer:

The slope means that every time the x value changes by +1, then the y value will change by +2.

The y-intercept is 3, which means is that when the y value is at 3, the line crosses the y-axis, or x has as value of 0.

For real though, why are there so many questions about slope and intercept, I just finished answering a question like this.

Step-by-step explanation:

Visualize a rectangle 4 units long and 2 units wide. Doesn't each part of the triangle seem to be a half of different parts of the rectangle?

Answer:

[tex]A^{'}[/tex] = {1,3,5,7,9,....}

[tex]B^{'}[/tex] = {1,2,4,5,7,8,10,11,13,14......}

[tex]C^{'}[/tex] = {1,2,3,4,5}

[tex]D^{'}[/tex] = {10,11,12,13,14,15,......}

Step-by-step explanation:

Solution:

It is given that, Universal set is the set of all Natural Numbers.

and

Set A, Set B, Set  C, Set D are subsets of Universal set.

A = {x:x is even natural numbers} = {2,4,6,8,10,.....}

B = {x:x ∈ N and x is a multiple of 3} = {3,6,9,12,15,....}

C = {x:x∈ N and x < 5} = {6,7,8,9,10,.....}

D = {x:x ∈ N and x > 10} = {1,2,3,4,5,6,7,8,9}

U = {1,2,3,4,5,6,7,8,9,10,11,........}

Complements:

[tex]A^{'}[/tex] = U-A = {1,2,3,4,5,6,7,8,9,10,11,........} - {2,4,6,8,10,.....}

[tex]A^{'}[/tex] = {1,3,5,7,9,....}

[tex]B^{'}[/tex] = U-B =  {1,2,3,4,5,6,7,8,9,10,11,........} - {3,6,9,12,15,....}

[tex]B^{'}[/tex] = {1,2,4,5,7,8,10,11,13,14......}

[tex]C^{'}[/tex] = U-C = {1,2,3,4,5,6,7,8,9,10,11,........} - {6,7,8,9,10,.....}

[tex]C^{'}[/tex] = {1,2,3,4,5}

[tex]D^{'}[/tex] = {1,2,3,4,5,6,7,8,9,10,11,........} - {1,2,3,4,5,6,7,8,9}

[tex]D^{'}[/tex] = {10,11,12,13,14,15,......}

Answer:15

Step-by-step explanation: 9^2+12^2=c^2 and solve :)

Answer:

C) x = 15

Step-by-step explanation:

This is a right triangle

to find the length of x (hypotenuse) we calculate the square sum of other two sides

9^2 + 12^2 = x^2

81 + 144 = x^2

225 = x^2

15 = x

Answer:

6 weeks

Cross multiply and solve for x:

4x = 24

x = 6

So, it will take 12 pupils 6 weeks to complete the job.

Answer:

C

Step-by-step explanation:

AP Classroom says so

The correct option should be C: "The variance of the sampling distribution of the estimator will increase" because the sample size is decreased from 2500 to 1500.

Given information:

The director originally planned to obtain a random sample of 2500 people who purchased the product.

However, because of budget concerns, the sample size will be reduced to 1500 people.

Now, the variance of the sample distribution can be written as,

[tex]\dfrac{\sigma^2}{n}[/tex] where n is the sample size.

So, the variance is inversely proportional to the sample size.

Here, we can conclude that with an increase in sample size, the variance will decrease and vice versa.

Therefore, the correct option should be C: "The variance of the sampling distribution of the estimator will increase" because the sample size is decreased from 2500 to 1500.
