The answer is C
The equation has x = 8/10
To get X by itself you need to divide both sides by 8, so the equation should become X = 10/8
The perimeter of a triangle is when u add all of the sides together
(8x - 7w) + (2x + 6y) + (3y + 5w) =
10x + 9y - 2w is ur perimeter
8w + 12x - 9y
8w + 12x - 9y
8w + 12x + 5y
8w + 12x - 9y
the 1st, 2nd, and 4th answer choices are the same....so 3 of them are equal
First, a scale factor is the ratio of the corresponding sides in two similar geometric figures.
To find the scale factor:
1. Locate two corresponding sides (one on each figure).
2. Write the ratio of one length to the other.
And there you go! That's the scale figure from one figure to the other
Hope that helps and correct me if I'm wrong!
The answer will be x=2i,-2i
Answer:
The significance level is 
and since we are conducting a right tailed test we need to find a critical value who accumulate 0.01 of the area in the right of the normal standard distribution and we got:
So we reject the null hypothesis is 
Step-by-step explanation:
For this case we define the random variable X as the number of entry-level swimmers and we are interested about the true population mean for this variable . On specific we want to test this:
Null hypothesis: 
Alternative hypothesis: 
And the statistic is given by:
The significance level is and since we are conducting a right tailed test we need to find a critical value who accumulate 0.01 of the area in the right of the normal standard distribution and we got:
So we reject the null hypothesis is
