Answer:
11.5
Step-by-step explanation:
Given that :
I am in charge of the pressure reading in a compressed air tank of a processing plant.
The Gaussian distribution having a mean value = 69 psi
Standard deviation = 10 psi
Here we have to find the probability that the pressure will exceed 84 psi.
So,



= 0.115
= 11.5
Answer:
0.006 is the probability that the record will be broken in next year.
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = 62 seconds
Standard Deviation, σ = 0.8 seconds
We are given that the distribution of face time is a bell shaped distribution that is a normal distribution.
Formula:
The record will be broken if the time is less than 60 seconds.
P(time is less than 60 seconds)
P(x < 60)
Calculation the value from standard normal z table, we have,

Thus, 0.006 is the probability that the record will be broken in next year.
Answer:
<em>-23x-16</em>
Step-by-step explanation:
-4(2x-6)-5(3x+8)
=-8x+24-15x-40
=-23x-16
Answer:
2.33 = x
Step-by-step explanation:
pages minutes
21 9
x 1
Cross multiply.
21×1 = 9×x
<u>21</u><u> </u> <u>9x</u>
9 9
9 cancels 9 leaving x. and 21 divided by 9 equals 2.33 pages. NB. both sides are divided by 9 because we want x by itself and what you do to one side, you have to do to the other.
Answer:
<h3>Hence required integers are 11 and 13</h3>
Let x an odd positive integer
Then, according to question
x^2 +(x+2)^2=290
2x^2 +4x−286=0
x^2 +2x−143=0
x ^2+13x−11x−143=0
(x+13)(x−11)=0
x=11 as x is positive
Hence required integers are 11 and 13
