pantera1 [17]

Answer:

Ava is 26 and Grace age is 9

Step-by-step explanation:

x=ava's age

y=grace's age

3y-1=x

x+y=35

Substitute 3y-1 to x+y=35 for the value of x to find grace age

3y-1+y=35

  4y-1=35

     +1  +1

4y=36

y=9       now substitute 9, the y value in 3y-1=x  to find ava's age

3(9)-1=x

x=26

to verify; 26+9=35

true 35=35

To find proportion of the area under the normal curve between two Z scores that are both above the mean, it is necessary to exam
VikaD [51]

It is necessary to imagine the sum of the areas between each z-score and the average.

Given as the ratio of the area under the normal curve between two z-scores, both above average.

The  Z score accurately measures the number of standard deviations above or below the mean of the data points.

The formula for calculating the z-score is

z = (data points – mean) / (standard deviation).

It is also expressed as z = (x-μ) / σ.

  • A positive z-score indicates that the data points are above average.
  • A negative z-score indicates that the data points are below average.
  • A z-score close to 0 means that the data points are close to average.
  • The normal curve is symmetric with respect to the mean and needs to be investigated.

Therefore, to find the percentage of the area under the normal curve between two z-scores, both above the mean, you need to look at the sum of the areas between the z-score and the mean.
