The one up top is 40 and 5x+10 should equal 40 as well because they are the same length.
you have to multiply something(the x) by 5 and add 10. So 6 times five is 30 plus ten equals 40.
5(x)+10=40
5(6)+10=40
30+10=40
40=40

Set 40 = 5x + 10
Subtract 10 on both sides, then divide 30 by 5
x = 6

During a flu epidemic, 35% of the school's students have the flu. Of those with the flu, 90% have high

frutty [35]

Answer: 0.8015

Step-by-step explanation:

Let F= event that a person has flu

H= event that person has a high temperature.

As per given,

P(F) =0.35

Then P(F')= 1- 0.35= 0.65 [Total probability= 1]

P(H | F) = 0.90

P(H|F') = 0.12

By Bayes theorem, we have

$P(F|H)=\dfrac{P(F)\timesP(H|F)}{P(F)\timesP(H|F)+P(F')\timesP(H|F')}\\\\=\dfrac{0.35\times0.90}{0.35\times0.90+0.65\times0.12}\\\\=\dfrac{0.315}{0.315+0.078}\approx0.8015$

Required probability = 0.8015
