Step-by-step explanation:
2x+11+6x-7=180
8x+4=180
8x=176
x=22
MHT= 6x-7

Answer:
(a) 13 ounces.
(b) 1.732 ounces.
(c) 0.5
(d) 0.33
Step-by-step explanation:
Given : The amount of water dispensed follows a continuous uniform distribution from 10 ounces to 16 ounces. So, a=10 and b=16.
(a) The average amount of water dispensed by the machine = (a+b)/2 = (10+16)/2 = 13 ounces.
(b) The standard deviation of the amount of water dispensed = = √36/12 =√3 = 1.732 ounces.
(c) P (13 or more ounces will be dispensed in a given glass) = = = 0.5
(d) P (between 12 and 14 ounces will be dispensed in a given glass) = ( here a=12 and b=14.) = = 0.33
Answer:
(x - 3) (x - 9) thus D:)
Step-by-step explanation:
Factor the following:
x^2 - 12 x + 27
The factors of 27 that sum to -12 are -3 and -9. So, x^2 - 12 x + 27 = (x - 3) (x - 9):
Answer: (x - 3) (x - 9)
I think c if it’s not right lmk
