Answer:
c) (40+60+25)/200 or 63%
Step-by-step explanation:
n= 200 students
Did Well on the Midterm and Studied for the Midterm = 75
Did Well on the Midterm and Went Partying = 40
Did Poorly on the Midterm and Studied for the Midterm = 25
Did Poorly on the Midterm and Went Partying = 60
The number of students that did poorly on the midterm or went partying the weekend before the midterm is given by the sum of all students who did poorly to all students who went partying minus the number of students who did Poorly on the Midterm and Went Partying:
![N=(25+60)+(40+60) - 60\\N= 125](https://tex.z-dn.net/?f=N%3D%2825%2B60%29%2B%2840%2B60%29%20-%2060%5C%5CN%3D%20125)
The probability that a randomly selected student did poorly on the midterm or went partying the weekend before the midterm is given by:
![P = \frac{N}{n}=\frac{125}{200} = 0.63 = 63\%](https://tex.z-dn.net/?f=P%20%3D%20%5Cfrac%7BN%7D%7Bn%7D%3D%5Cfrac%7B125%7D%7B200%7D%20%3D%200.63%20%3D%2063%5C%25)

Answer:
a)Volume 390ft3. Surface area 450ft2
b)surface area
c)volume
Step-by-step explanation:
2*15*13=390
2*15*2=60+15*13*2=390
The hypotenus square is equivalent to the sum of the square of base and perpendicular.

Answer:
x = 3 and x = 11
Step-by-step explanation:
To find the app price (x) that will result in 0 annual profit, we just need to make P(x) = 0 and then find the value of x:
P(x) = -2*(x-3)*(x-11)
0 = -2*(x-3)*(x-11)
(x-3)*(x-11) = 0
To make this equation equal to zero, we just need to have (x-3) = 0 or (x-11) = 0
So, the values that give P(x) = 0 are:
(x-3) = 0 -> x = 3
and
(x-11) = 0 -> x = 11
