9 - w = 2

9 - 7 = 2

If this is what you mean.

9-w would be the simpliest form.

But, if you meant, to= 2, then:

9-w= 2

Subtract 9 on both sides.

-w= -7

Divide by -1, since the w cannot be negative.

w= 7

We can check this by plugging it in.

9-(7)= 2
2=2 <- this works

I hope this helps! Let me know if I need to make any changes.

The given sample's confidence interval is 4.73 ± 0.1199, or from 4.61 to 4.85

<h3>What is the z score?</h3>

The z-score is a numerical assessment of a value's connection to the mean of a set of values, expressed in terms of standards from the mean, that is used in statistics.

Given data;

Mean = 4.73

Standard deviation = 0.865

Sample size = 200

interval = 95%

Confidence interval=?

95% of samples contain the population mean (μ) within the confidence interval of 4.73 ± 0.1199.

Hence, the sample's confidence interval is 4.73 ± 0.1199, from 4.61 to 4.85

The sum of liz's and melinda's ages is 28. if liz was 1/3 melinda's age 6 years ago, how old will liz be next year?

Mrrafil [7]

The first thing we must do for this case is to define variables:
We have then:
x: liz's age
y: melinda's age
We now write the system of equations:
$x + y = 28

x-6 = (1/3) (y-6)$
By solving the system graphically we have that the age of each one is currently:
$x = 10

 y = 18$
Next year, the age of liz is:
$x + 1 = 10 + 1 = 11
$
Answer:
Next year, Liz's age is 11 years.
Note: see attached image for the graphic solution.
