Answer:
2x³-3x²+4
Step-by-step explanation:
F(x) = 2x-1
g(x)=x²-2
g.f(x) = (x²-2)(2x-1)
open the bracket
x²(2x-1)-2(x²-2)
2x³-x²-2x²+4
2x³-3x²+4
Answer:
The probability that applicants would you expect to have scores of 600 or above = 0.0401 or 4%
Step-by-step explanation:
<u><em>Explanation</em></u>:-
<em>Let "x" Scores are normally distributed </em>
<em> Given mean of the Population = 460 </em>
<em> standard deviation of the population = 80</em>
Let X = 600
<em>The probability that applicants would you expect to have scores of 600 or above</em>
<em>P( X≥600) = P( Z≥ 1.75) </em>
= 1- P( Z≤1.75)
= 1- ( 0.5 + A(1.75)
= 1- 0.5 - A(1.75)
= 0.5 - 0.4599 (from Normal table)
= 0.0401
<em>The probability that applicants would you expect to have scores of 600 or above = 0.0401 or 4%</em>
Answer: 4(x/14) or 4•x/14
Explanations:
X= the unknown valued number
( ) and / = dividing

</span>Two-Thirds of the 96 members approved the plan
Question: What percent of the members did not approve of the plan?
=> two third means 2/3, thus there are 1/3 of them did not agree.
First to get the value let’s divide 96 by 3 .
=> 96 / 3 = 32
=> 32 * 6 = 64
32 = the number of people that did not agree with the plan
64 = is the total number of people that agree with the plan.</span>
