Sum of all three angles of a triangle must be equal 180.
Let's add all the the angles of the given choices to get the correct answer.
A: 45+60+75=180
Sum of 45°,60°, and 75° is 180°. So, A is the correct answer.
Answer:
B(0.7, 100)
Step-by-step explanation:
Probability of contracting a certain disease = 0.70
No of individual randomly selected = 100
Contracting the disease is a positive/success in this case, hence
p = 0.7 and since there are 100 selection, the binomial distribution B(0.7, 100)
Hence, the The random variable describing the number of individuals who will contract the disease is B(0.7, 100) distribution.
And Mean = 0.7 x 100 = 70
Answer:
answer will be 120°
Step-by-step explanation:
as those are similar angles
Answer:
36
Step-by-step explanation:
keep, flip, change...
24 ÷ 
would be the same as 
× 
which is equal to 
(36 if you simplify it)
You have to solve the exponent in the parentheses first:
(2^4)^2
(16)^2
=256
