Answer:
x = 114
Step-by-step explanation:
since the triangles are congruent then corresponding angles are congruent, then
∠ C = ∠ D , that is
x + 18 = 132 ( subtract 18 from both sides )
x = 114
Answer:
A = 1 , 1 , 
Step-by-step explanation:
Given equation as
(2a -5) (a² -2a +1) = 0
Or, (2a - 5) (a - 1 )² = 0
Or, (2a - 5) (a - 1) (a - 1) = 0
So, value of a are :
2a - 5 =0, a - 1 =0, a- 1 = 0
i.e a = 
and a = 1 , 1
Answer
Answer:
No, they are not equal
Step-by-step explanation:
If x = 1
4(5+x) = 4(5+1) = 4 x 6 = 24
(5+4) + x = 9 +1 = 10
24
10
Answer:
90
Step-by-step explanation:
10x - x = 81
9x = 81
x = 9
larger number = 10 x 9 = 90
Answer:
A. We have extremely strong evidence to reject H0.
Step-by-step explanation:
Let P be the proportion of non-retirees in 2015 who did not think that Social Security would be able to pay a retirement benefit by the time that they retire.
According to the data null and alternative hypotheses should be:
: P=0.60
: P<0.60
Test statistics is -4.29 and p-value of the statistics is p<0.001
At every significance levels higher than 0.001, we can reject the null hypothesis since p<0.001.
