X in less than or equal to 4.5. it is this because 32 is the least number of miles per gallon. 144/32=4.5.
Answer:
D) 20.
Step-by-step explanation:
First find the value of x using Pythagoras theorem:
10^2 = x^2 + (2x)^2
5x^2 = 100
x^2 = 20
x = √20
= 2√5.
So the area of triangle
= 1/2 * base * height
= 1/2 * 2x * x
= x^2
= (2√5)^2
= 20.
Answer:
I think they are congruent
Answer:
Step-by-step explanation:
Given that
,
The weibull distribution with parameters 
where 

Then,

A) The probability that a specimen's lifetime is at most 250 is

The probability that the specimen's life time is more than 300 is


= 0.0992
b)The probability of the specimen's lifetime is between 100 and 250

c) The value such that exactly 50% of all specimens have lifetimes exceeding that value is

x = 192.07
