Answer:
i think the answer is: 6:8
Step-by-step explanation:
you just add 5:6 + 1:2= 6:8 and to check, you subtract 6:8-1:2
I think you have to divide 63 by 8 which will give you 7.875 (8).
You can write it as an equation: 8x n=63
n=7.8
For the rectangle do 10x15 to get 150cm squared
14-10 is 4 so triangle height is 4
Width is 5 as given
4x5 is 20 divide by two as triangle so 10cm squared
150+10=160cm squared
Answer:
decreases.
Step-by-step explanation:
Type II error is one in which we fail to reject the null hypothesis that is actually false. Null hypothesis is a statement that is to be tested against the alternative hypothesis and then decision is taken whether to accept or reject the null hypothesis. The power of Type II error is 1 - 
. As the power increases the probability of Type II error decreases.
Answer:
-7
Step-by-step explanation:
8x - 2 = 7x - 9
8x - 2 - 7x = 7x - 9 - 7x
x - 2 = -9
x - 2 + 2 = -9 + 2
x = -7
