ANYONE GOOD AT MIDPOINT?​

Mathematics
1 answer:
Vladimir79 [104]3 years ago
3 0

The coordinates of the midpoint of two points A and B are the averages of the corresponding coordinates of A and B.

So if one point is (a, b) and another point is (c, d), the point exactly between them has coordinates ((a+b)/2, (c+d)/2).

In this example, the points

A(-3a, b)

B(3a, b)

have midpoint

F((-3a+3a)/2, (b+b)/2) = F(0, 2b/2) = F(0, b)

Which equation represents the line that passes through the points (6, 7) and (-3, -2)?
Scrat [10]

(6, 7) and (-3, -2)

1. Find the slope.

m = slope

m = (-2 -7)/(-3 -6)

m = -9/-9

m = 1

2. Plug the slope and one of the points into the equation y - y_1 = m(x - x_1).

y - 7 = 1(x - 6)

3. Solve for y.

y - 7 = x - 6

y = x - 6 + 7

y = x + 1

Answer is choice D.

Dr. Vegapunk thinks that watching anime (Japanese animated shows) decreases social skills in college students. To test this, Dr.
Allisa [31]

Answer:

The test statistic = 2.51

Step-by-step explanation:

For hypothesis testing, the first thing to define is the null and alternative hypothesis.

The null hypothesis plays the devil's advocate and usually takes the form of the opposite of the theory to be tested. It usually contains the signs =, ≤ and ≥ depending on the directions of the test.

While, the alternative hypothesis usually confirms the the theory being tested by the experimental setup. It usually contains the signs ≠, < and > depending on the directions of the test.

For this question, Dr. Vegapunk wants to test the claim that watching anime decreases social skills in college students.

So, the null hypothesis would be that there isn't significant evidence to conclude that watching anime decreases social skills in college students. That is, watching anime does not decrease social skills in college students.

And the alternative hypothesis is that there is significant evidence to conclude that watching anime decreases social skills in college students.

If the previous known mean social skills of college students is 6.2 and the new population mean social skills of college students who watch anime is μ,

Mathematically,

The null hypothesis is represented as

H₀: μ ≥ 6.2

The alternative hypothesis is given as

Hₐ: μ < 6.2

To do this test, we will use the t-distribution because no information on the population standard deviation is known

So, we compute the t-test statistic

t = (x - μ)/σₓ

x = sample mean = 7.3

μ₀ = Standard to be compared against = 6.2

σₓ = standard error of sample mean = [σ/√n]

where n = Sample size = 30

σ = Sample standard deviation = 2.4

σₓ = (2.4/√30) = 0.4382

t = (7.3 - 6.2) ÷ 0.4382

t = 2.51

Hope this Helps!!!
