Sure I can help to the best of my ability if possible . Only on mathematics
I'm not really sure, but I think the answer is D
The formula for point slope form is (y-y1) = m(x - x1)
In this formula m will always be the slope. So, you can substitute 3 in for m
(y-y1) = 3(x-x1)
y1 is the y-coordinate and x1 is the x-coordinate. So, you can substitute them in and you will be done.
(y - 1) = 3(x - (-2))
But since it is minus a negative it changes to a positive so it would be:
(y -1) = 3(x + 2)
Hope this helps!
Answer:
The mean of the z scores will be 0, and the standard deviation of the z scores will be 1.
Step-by-step explanation:
When the data is converted to z-scores the mean and standard deviation no longer stay the same. Both these quantities are transformed into news values.
Values converted to z scores follow a standard Normal curve. This curve is symmetric about the mean. The mean of standard normal curve is 0 with a standard deviation of 1.
Therefore, the correct answer is:
The mean of the z scores will be 0, and the standard deviation of the z scores will be 1.
Hello!
We assign (5x + 24) to angle one and (9x - 7) to angle two. If these angles are congruent, then angle one is equal to angle two. To find the value of x, you need to create and equation as follows: 5x + 24 = 9x - 7 and find the value of x like a normal algebraic equation.
5x + 24 = 9x - 7 (subtract 5x from both sides)
24 = 4x - 7 (add 7 to both sides)
31 = 4x (divide 4 to both sides)
x = 31/4
Therefore, the value of x is equal to 31/4.
