Answer:
Step-by-step explanation:
Here we found out that the two samples are independent, so we can use independent t test for testing the average batting rattlers and Vikings
Independent group mean, the population standard deviation and / population variance known.
Improper fractions have a greater numerator than the denominator:
8 = 8*(10/10) = 80/10
now add
8 + 9/10
80/10 + 9/10
(80 + 9)/10
89/10
4/5

Answer:
41
Step-by-step explanation:
BDA = DBC+CBA
84=5x+3 + 6x-7
Combine like terms
84 = 11x-4
Add 4 to each side
84+4= 11x -4+4
88 =11x
Divide each side by 11
88/11 = 11x/11
8 = x
We want angle ABC
ABC = 6x-7
=6*8 -7
=48-7
=41
This is called a unit rate.
