Step-by-step explanation:
Consider the provided information.
Consider the figure 1:
We need to give an example of a pair of alternate interior angles, a pair of corresponding angles, and a pair of alternate exterior angles.
Alternate interior angles: If a transversal cuts two parallel line then pair of angles on the inner side of lines but on opposite sides of the transversal are know as the alternate interior angle:
For example: ∠3 and ∠6 are alternate interior angle another pair are ∠4 and ∠5.
Corresponding angles: If a transversal cuts two parallel line then the angles in same corner are called corresponding angles.
For example: ∠1 and ∠5 are corresponding angle another pair are ∠4 and ∠8.
Alternate exterior angles: If a transversal cuts two parallel line then the pair of angles on the outer side of lines but on opposite sides of the transversal are known as the alternate exterior angles.
For example: ∠1 and ∠8 are alternate exterior angle another pair are ∠2 and ∠7.
Answer:
See below ~
Step-by-step explanation:
<h3>What number represents the slope?</h3>
The slope refers to the rate of change of the equation.
Here, the slope is 1473 as that is the value that is multiplied on increasing the number of classes.
It represents the price per class.
<h3>What number represents the y-intercept?</h3>
The y-intercept refers to where the line intersects the y-axis.
Here, the y-intercept is 5495.
It represents the one time fee for room and board.
This question is incomplete, the complete question is;
Assume that two samples are independent simple random samples selected from normally distributed populations, and do not assume that the population standard deviations are equal. Which distribution is used to test the claim that women have a higher mean resting heart rate than men?
A.t
B.F
C.Normal
D. Chi-square
Answer:
A) t test
Step-by-step explanation:
A t-test uses sample information to assess how plausible it is for the population means μ1 and μ2 to be equal.
The formula for a t-statistic for two population means (with two independent samples), with unknown population variances shows us how to calculate t-test with mean and standard deviation and it depends on the assumption of having an equal variance or not.
If the variances are assumed to be not equal,
he formula is:
t = (bar X₁ - bar X₂) / √( s₁²/n₁ + s₂²/n₂ )
If the variances are assumed to be equal, the formula is:
t = (bar X₁ - bar X₂) / √ (((n₁ - 1)s₁² + (n₂ - 1)s₂²) / (n₁ + n₂ - 2)) ( 1/n₁ + 1/n₂)
it called t-test for independent samples because the samples are not related to each other, in a way that the outcomes from one sample are unrelated from the other sample.
hence option A is correct. t test
