Answer:

x = 3\ or\ x = 7

Step-by-step explanation:

Given

x^{2}-8x+14=2x-7

Required

Solve

Equate to 0

x^{2}-8x-2x+14+7=0

x^{2}-10x+21=0

Expand

x^{2}-7x-3x+21=0

Factorize

x(x-7)-3(x-7)=0

Factor out x - 7

(x-3)(x-7)=0

Split

x - 3 = 0\ \ x - 7 = 0

Solve

x = 3\ or\ x = 7

Are you smarter than a second grader? A random sample of 60 second graders in a certain school district are given a standardized
denis23 [38]

Answer:

We accept H₀ , we do not have enought evidence for rejecting H₀

Step-by-step explanation:

Normal Distribution

sample size   n  =   60

standard deviation     σ  =  15

1.Hypothesis Test : Is a one tailed-test on the right

H₀      null hypothesis             μ₀  = 50

Hₐ    alternative hypothesis   μ₀  > 50

2.-We will do the test for  a significance level   α =  0,01 tht means for a 99% interval of confidence

then z(c)  =  2.32

3.- We compute z(s)  

z(s)  =  [ ( μ - μ₀ ) /( σ/√n )       ⇒  z(s)  =  (  2 * √60 ) / 15

z(s)  = 15.49/15                        ⇒   z(s)  = 1.033

4.- We compare values of  z(c)   and z(s)

z(s)  <  z(c)      1.033 < 2.32

z(s) is in the acceptance region so we accept H₀ , we do not have enough evidence for rejecting H₀
