Answer:
A)
Step-by-step explanation:
The triangle TRS is isosceles (Angle T = Angle R)
Then sides TS = RS and both are shorter than TR
A) TR > TS True
B) TR < TS False (TR > TS)
C) TR < RS False (TR > RS)
D) RS < TS False (RS = TS)
Answer:
42
Step-by-step explanation:
Since Gabrielle is 7 years older than Mikhail, we subtract 7 from 91. Then we divide it by 2. So 84/2=42. Since Gabrielle is 7 years older we add 7 to 42. She is 49 and Mikhail is 42 years old. To double check our answer we should add both of the ages we got to make sure they add up to 91, so 42+49 is 91.
Is there more to this question? I feel like there is not enough information. Perhaps the probability is low because in order to survive, she must work. Many jobs may not require schooling. Sorry if this didn’t help.
Step-by-step explanation:
16 = 20% to get to 80% we need to times by 4 so it adds up to 100%
64=80%
the orginal price was 64 dollars
Answer:
np = 81 , nQ = 99
Step-by-step explanation:
Given:
X - B ( n = 180 , P = 0.45 )
Find:
Sampling distribution has an approximate normal distribution
Computation:
nP & nQ ≥ 5
np = n × p
np = 180 × 0.45
np = 81
nQ = n × (1-p)
nQ = 180 × ( 1 - 0.45 )
nQ = 99
