Which is a solution to the equation? (x - 3)(x - 5) = 35 x= -8 x=-5 x=2 x = 10

JulijaS [17]

(x-3)(x-5)=35

Multiply the brackets together

x*x-5*x-3*x-3*5

x^2-8x+15=35

Move +35 to the other side. Sign changes from +35 to -35

x^2-8x+15-35=35-35

x^2-8x-20=0

(x-10)(x+2)=0

x-10=0 x+2=0

Move -10 to the other side. Sign changes from -10 to +10

x-10+10=0+10 x+2-2=0-2

x=10 x=-2

Answer: x=10

Students at a certain school were surveyed, and it was estimated that 10% of college students abstain from drinking alcohol. T

Answer:

you are unwilling to predict the proportion value at your school = 0.90

b)

The large sample size 'n' = 864

Step-by-step explanation:

Given estimated proportion 'p' = 10% = 0.10

Given Margin of error M.E = 0.02

Level of significance α = 0.05

you are unwilling to predict the proportion value at your school

q = 1- p = 1- 0.10 =0.90

The Margin of error is determined by

$M.E = \frac{Z_{\frac{\alpha }{2} } \sqrt{p(1-p)} }{\sqrt{n} }$

$0.02 = \frac{1.96 X \sqrt{0.10 (0.90)} }{\sqrt{n} }$

Cross multiplication , we get

$\sqrt{n} = \frac{1.96 X \sqrt{0.10 (0.90)} }{0.02 }$

√n = 29.4

Squaring on both sides , we get

n = 864.36

Conclusion:-

The large sample size 'n' = 864
