Answer:
The equation of the line is:
Step-by-step explanation:
Given the points
Finding the slope between the points
We know the slope-intercept form of the line equation
where m is the slope and b is the slope-intercept form
substituting the value m=2 and the point (-2, -5) to find the b-intercept
-5 = 2(-2) + b
b = -5+4
b = -1
Now, substituting m=2 and b=-1 in the slope-intercept form to get the equation of a line
y=mx+b
y=2x+(-1)
y=2x-1
Thus, the equation of the line is:
Answer:
x = 2 and x = -3
Step-by-step explanation:
We need to find the value of x in the below expression.
Adding 1 to both sides,
Squaring both sides,
Hence, this is the required solution.
Answer:
A. n = 22
Step-by-step explanation:
Hello!
The researcher conducted a one-sample t-tas with the following hypotheses:
H₀: μ = μ₀
H₁: μ ≠ μ₀
α:0.05
The one-sample t-test has "n-1" degrees of freedom and since the hypotheses are two-tailed you know that the rejection region will be divided into two tails with "α/2" for each tail. ±
If α:0.05 then α/2:0.025 and 1-α/2= 0.975
Using the given sample sizes as a reference you look in the table for the corresponding DF for an accumulated probability of 0.975
For n = 22
For n= 21
For n= 20
The correct answer is a) n= 22
I hope this helps!
