The scores of an eighth-grade math test have a normal distribution with a mean Mu = 83 and a standard deviation Sigma = 5. If Di
tresset_1 [31]

The missing choices are:

A. z-score = 92 - 83

B. z-score = (92 - 83)/5

C. z-score = 83 - 92

D. z-score =  (92 - 83)/92

The expression she would write to find z-score is z-score = \frac{92-83}{5} ⇒ B

Step-by-step explanation:

The rule of z-score is z = (x -μ)/σ, where

  • x is the score
  • μ is the mean
  • σ is the standard deviation

The scores of an eighth-grade math test have a normal distribution

∵ The mean is 83

∴ μ = 83

∵ The standard deviation is 5

∴ σ = 5

∵ Din’s test score was 92

∴ x = 92

- Substitute all of these values in the formula of z-score

∴ z-score = \frac{92-83}{5}

The expression she would write to find z-score is z-score = \frac{92-83}{5}

X + 2xy- y^2 = 2<br><br> find dy/dx using implicit differentiation
AleksandrR [38]

Answer:

hope that helps

Step-by-step explanation:

3x^2+2xy+y2=2

6x + 2y + 2xy' + 2yy' = 0

x=1 ==> y=-1

6(1) + 2(-1) + 2(1)y' + 2(-1)y' = 0

6 - 2 + 2y' - 2y' = 0

4 = 0

(e) undefined
