Answer:
18in
Step-by-step explanation:
Given data
Height h= 15 in
Area= 135 in^2
The expression for the area is given as
Area= 1/2 Base * Height
substitute
135= 1/2* Base*15
135= 7.5 Base
Base= 135/7.5
Base= 18 in
Hence the base is 18in
hope it helped. I have solved in the same paper. plz don't mind.
Answer:
A, C are true . B is not true.
Step-by-step explanation:
Mean of a discrete random variable can be interpreted as the average outcome if the experiment is repeated many times. Expected value or average of the distribution is analogous to mean of the distribution.
The mean can be found using summation from nothing to nothing x times Upper P (x) , i.e ∑x•P(x).
Example : If two outcomes 100 & 50 occur with probabilities 0.5 each. Expected value (Average) (Mean) : ∑x•P(x) = (0.5)(100) + (0.5)(50) = 50 + 25 = 75
The mean may not be a possible value of the random variable.
Example : Mean of possible no.s on a die = ( 1 + 2 + 3 + 4 + 5 + 6 ) / 6 = 21/6 = 3.5, which is not a possible value of the random variable 'no. on a die'
Answer:
The amount of money A pays is 
Step-by-step explanation:
Let
x-----> amount of money A pays
y-----> amount of money B pays
we know that
------> equation A
so
------> equation B
substitute equation B in equation A and solve for x
Answer:
f(3)=1
Step-by-step explanation:
take f(x)=2(x)-5
put a three wherever you see an x in parentheses
f(3)=2(3) - 5
simplify
f(3)=6-5
simplify
f(3)=1
answer:f(3)=1
