Which equation does the graph of the systems of equations solve? 2 linear graphs. They intersect at 0,3

Mathematics

Answer:

D. 2x+3=-8x+3

Step-by-step explanation:

We have been given a graph of system of linear equations and we are asked to choose the system of equations representing the given graph.

Upon looking at our graph we can see that our lines intersect at point (0,3). To find the system of equations represented in the graph we will substitute x=0 in our given equations and see which equation gives us an output of 3.

Let us start with 1st option.

A. -2x+3=8x-3

Upon substituting x=0 we will get

-2*0+3=8*0-3

0+3=0-3

3\neq-3

Since we get 3 on one side of equation and -3 on other side of equation, therefore, option A is not a correct choice.

B. -2x+4=-8x+4

Upon substituting x=0 we will get,

-2*0+4=-8*0+4

0+4=0+4

4=4

Since this system of equations intersect at point (0,4), therefore, option B is not a correct choice as well.

C. 2x+4=8x-4

Upon substituting x=0 we will get,

2*0+4=8*0-4

0+4=0-4

4\neq-4

Therefore, option C is not a correct choice as well.

D. 2x+3=-8x+3

Upon substituting x=0 we will get,

2*0+3=-8*0+3

0+3=0+3

3=3

Since this system of equations intersect at point (0,3), therefore, option D is the correct choice.

A researcher reports the following confidence interval for a comparison of the difference between two groups: 95% CI −12.0 [−30.
Lapatulllka [165]

Answer:

Decision: Support the null hypothesis.

Sample mean: -12

Step-by-step explanation:

Hello!

When deciding with a Confidence interval you have to keep in mind that the following conditions are met:

  • The hypothesis and the interval are made for the same parameter.
  • The hypothesis should be two-tailed.
  • The interval and the test have to have complementary confidence and signification levels. This means that if the interval is made with 1 - α= 0.95 the hypothesis test should be made with α= 0.05.

H₀: μ₁ - μ₂= 0

H₁: μ₁ - μ₂≠ 0

α: 0.05

If the interval contains the cero, it means that there is no difference between the means, so you support the null hypothesis.

If the interval doesn't contain the cero, there is a difference between the two means, so you reject the null hypothesis.

The intervals to estimate the population mean have the following structure:

Estimator ± Margin of error

This means that the sample mean (point estimate of the population mean) is in the middle of the calculated interval. To know it's the value you have to do a simple calculation:

sample mean: \frac{Upper bound + Lower bound}{2}

sample mean: \frac{6 + (-30)}{2}

sample mean: -12

I hope it helps!
