62 + 22 = 84 total light strings.
36 bulbs/string multiplied by 84 light strings = 3,024 total light bulbs
Answer:
a. P(X=50)= 0.36
b. P(X≤75) = 0.9
c. P(X>50)= 0.48
d. P(X<100) = 0.9
Step-by-step explanation:
The given data is
x 25 50 75 100 Total
P(x) 0.16 0.36 0.38 0.10 1.00
Where X is the variable and P(X) = probabililty of that variable.
From the above
a. P(X=50)= 0.36
We add the probabilities of the variable below and equal to 75
b. P(X≤75) = 0.16+ 0.36+ 0.38= 0.9
We find the probability of the variable greater than 50 and add it.
c. P(X>50)= 0.38+0.10= 0.48
It can be calculated in two ways. One is to subtract the probability of 100 from total probability of 1. And the other is to add the probabilities of all the variables less than 100 . Both would give the same answer.
d. P(X<100)= 1- P(X=100)= 1-0.1= 0.9
Step-by-step explanation:
The next step is
12 = - 2x
12 / - 2 = x
-6 = x
They baked 2 dozen because each dozen is 12 so one did 17 + another did 11 = 28 and divide it by 12 get. 2 dozens.
Per gallon means you multiply for each gallon.
