The answer to the questions
Answer:
x = 5 
Step-by-step explanation:
Hi there!
So, to answer this problem, I'll use the reverse method.
31 - 4 = 27,
So how many times, can 5 go into 27?
The closest factor of 5 to 27 is 25.
5 can go in to 27, 5 times.
Continuing on, there is a 2 left over, so the answer to your question is
x = 5
5 · 5 - 4 = 31
Let me know if I am incorrect and I will attempt to find the right answer for you.

120
Step-by-step explanation:
LCM=1320
(GDC) HCF=12
Another no.=132
let second no. be =A
According to question
First no.×Second no.=HCF×LCM
132×A=12×1320
132×A=15840
A=15840/132
A=120
Other no. is 120
Answer:
72°
Step-by-step explanation:
There are 5 blades, equally spaced. So the angle between adjacent blades is 360° / 5 = 72°. So you can rotate the fan 72° and the blades will align again.
Answer:
Step-by-step explanation:
Since the number of pages that this new toner can print is normally distributed, we would apply the formula for normal distribution which is expressed as
z = (x - µ)/σ
Where
x = the number of pages.
µ = mean
σ = standard deviation
From the information given,
µ = 2300 pages
σ = 150 pages
1)
the probability that this toner can print more than 2100 pages is expressed as
P(x > 2100) = 1 - P(x ≤ 2100)
For x = 2100,
z = (2100 - 2300)/150 = - 1.33
Looking at the normal distribution table, the probability corresponding to the z score is 0.092
P(x > 2100) = 1 - 0.092 = 0.908
2) P(x < 2200)
z = (x - µ)/σ/√n
n = 10
z = (2200 - 2300)/150/√10
z = - 100/47.43 = - 2.12
Looking at the normal distribution table, the probability corresponding to the z score is 0.017
P(x < 2200) = 0.017
3) for underperforming toners, the z score corresponding to the probability value of 3%(0.03) is
- 1.88
Therefore,
- 1.88 = (x - 2300)/150
150 × - 1.88 = x - 2300
- 288 = x - 2300
x = - 288 + 2300
x = 2018
The threshold should be
x < 2018 pages
