G two samples, one of size 14 and the second of size 13, are selected to test the difference between two population means. how m
vovikov84 [41]

Note :- If sample size n > 30 OR Population standard deviation σ is given then We use Z test.

If sample size n < 30 AND Population standard deviation σ is unknown then we use t test.

In this question we are not given Population standard deviations σ1 and σ2.

Also n1 = 14 and n2 = 13 both sample sizes are LESS than 30.

Therefore we use t test.

Given :- Assume the population standard deviations are equal. ( σ1 = σ2)

then Degrees of freedom = n1 + n2 - 2 = 14 + 13 - 2 = 25.

(kindly find the image attached with this solution)

Answer :- Therefore 25 degrees of freedom are used to find the t critical value.

What is the x-intercept of the equation -7x+3y=21
mezya [45]
Hello!!

Well, the x-intercept is found when y = 0, so plug in y = 0:

-7x + 3(0) = 21
-7x = 21
x = -3

Therefore, the x-intercept of -7x + 3y = 21 is -3.

Hope this helps!! Let me know if you have ANY questions.

Lilia is saving money for dance lessons. She already has $10. Each week she is going to save $5. Write an equation, in slope-int
katrin [286]

The equation which represents the amount of money, y, that Lilia will save in x weeks is;

  • y =$5x + $10.

<h3>Slope-intercept form of linear equations</h3>

The slope-intercept form of linear equations usually takes the form;

  • y = mx + c

According to the information given;

  • Lilia already has $10.

Therefore, the y-intercept of the equation is; $10.

  • And since she saves $5 each week;

The slope of the equation is; $5.

By substitution, the required equation is;

  • y =$5x + $10.
