Answer:
m<A = 120°
m<C = 45°
Step-by-step explanation:
We can use the triangle sum theorem to find the measures of the angles.
m<A + m<B + m<C = 180°
Then substitute in their given values.
12x + 12 + 15 + 3x + 18 = 180°
Now simplify the equation and you get
15x + 45 = 180°
Continue to solve
15x = 135
x = 9°
Now substitute this value of 9 for the angle expressions of <A and <C
(12 x 9) +12 = m<A
m<A = 120°
(3 x 9)+ 18 = m<C
m<C = 45°
Hope this helps. To check your answer you can add up all the answers to see if it equals 180°.
Answer:
Test statistic =1.30
Step-by-step explanation:
Given that you are testing the claim that the proportion of men who own cats is significantly different than the proportion of women who own cats.
Men Women Difference
Sample size n 60 120
Proportion p_1, p_2 0.45 0.35 0.10
60 120 180
0.45 0.35 0.383333333
27 42 69
p = 0.3833
Std error for proportion difference =
Test statistic =
=
=1.30
