Answer:
True.
Step-by-step explanation:
In t-test test the value of t can be either negative or positive.
If value of t is negative, then it lies to the left of the mean.
If value of t is Positive, then it lies to the right of the mean.
The given statement is "When you conduct a t test, the calculated value of t can be negative.".
Therefore, the given statement is true.
Answer:
9 1/2 or 9.5
Step-by-step explanation:
First you have to get the t all alone to find the value so you divide both sides by 2
19/2= 9 1/2 2t / 2 =t
t = 9 1/2
9 1/2 as a decimal is 9.5 so it could also be 9.5
Hey there!
Conveniently, not a lot of math is required on this one. Let's go through slope intercept form, which is defined as:
y = mx+b
m = slope
b = y intercept
We know that parallel lines must have the same slope. Therefore, our new slope is 1/2. Now normally, we'd have to solve for the y intercept, but we're lucky this time. It's already given to us in the form of (0, -2) - which means the line crosses the y-axis at (0, -2).
That means your equation is:
y = 1/2x - 2
Hope this helps!
"Betsy gets her hair cut every 28 days and Mary gets hers every 35 days"
Find the least common multiple of 28 and 35.
28 = 2²×7
35 = 5×7
LCM(28, 35) = 2²×5×7
= 140
Answer:
A. 130 degrees
B. 50 degrees
Step-by-step explanation:
A. It's a straight line so the angle is 180. U subtract 50 from. 180 and u get 130
B. It 50 because it's vertically opposite angle to angle AEC
