For every four [measurement unit] of blue paint, there is two [measurement unit] of yellow paint.
Answer:
Its D
Step-by-step explanation:
Given, they are supplementry
hence their sum is 180 degree
now, 2x+5+3x-10=180
or, 5x-5=180
or, 5x=185
or, x=185÷5
or, x=37
Then, here we have measures of angle k is
3×37-19
=101
For summing the terms of an arithmetic series use this
a1 is the first term and d is the difference between second and first term
Answer:
73.33% probability that the time will be at most 15 minutes.
Step-by-step explanation:
An uniform probability is a case of probability in which each outcome is equally as likely.
For this situation, we have a lower limit of the distribution that we call a and an upper limit that we call b.
The probability that we find a value X lower than x is given by the following formula.

Uniform distribution between 4 and 19 minutes.
This means that 
Find the probability that the time will be at most 15 minutes.


73.33% probability that the time will be at most 15 minutes.
