Answer:
42.9m
Step-by-step explanation:
The topic is on similar triangle
you are comparing triangle MNP with triangle MAB
side AB is similar to NP
side MA is similar to MN
side MB is similar to MP
now MA = MN - AN
= 67.2 - 32
= 35.2m
MA/MN = MB/MP
35.2/67.2 = x/81.9
cross multiply and solve
x = 42.9m
Answer:
-1
Step-by-step explanation:
2(.5n-3)=n-0.25(12-12n)
first you distribute whatever is on the outside of the parenthesis to the inside of the parenthesis
1n-6=n-3+3n
then you combine like terms and end up with
1n-6=-3+4n
add 6 to each side to get
n=3+4n
subtract 4n from each side to get
-3n=3
divide -3 from each side to get
n=-1
8÷41.92
=8÷1048/25
=8x25/1048
=25/131
This is your answer.
Answer:
The probability that a randomly chosen person has measles antibodies in his/her blood if the new test is positive = 0.9796
Step-by-step explanation:
The event that someone tests positive = P(T)
The event that someone has antibodies = P(A)
The event that someone does not have antibodies = P(A')
The new test was positive when administered to 96% of those who have the antibodies.
This probability = P(T n A) = 0.96
The new test gave positive results in 2% of those who do not have them.
This probability = P(T n A') = 0.02
The probability that a randomly chosen person has measles antibodies in his/her blood if the new test is positive = P(A|T)
This conditional probability is given as
P(A|T) = P(T n A) ÷ P(T)
P(T) is given as
P(T) = P(T n A) + P(T n A') = 0.96 + 0.02 = 0.98
P(A|T) = P(T n A) ÷ P(T) = 0.96 ÷ 0.98 = 0.9796

Solution:
When you are finding the percent of a number, turn that percent into a decimal and multiply.
~Turn 11% to a decimal
11 / 100 = 0.11
~Multiply
2,720 x 0.11 = 299.2
