I totally forgot how to find a z-score. Please help and explain.
mash [69]

The z-score is the number of standard deviations from the mean. For a given x-value, mean (μ), and standard deviation (σ) the z-score is given by

... z = (x -μ)/σ

(a) x=196, μ = 180, σ = 8 gives a z-score of

... z = (196 -180)/8 = 16/8

... z = 2.0

(b) The area associated with x=2 is 0.4772

(c) Rounded to the nearest thousandth, this is 0.477

(d) Carl's subtraction gives

... 0.50 - 0.477 = 2.3%

A rectangular box has a length of 8 feet and a width of 2 feet. The length of the three-dimensional diagonal is 10 feet. What is
harkovskaia [24]

Answer: h=5.66ft

Step-by-step explanation:

Observe the picture attached.

Find the value of "x" and "y" using the Pythagoren Theorem:

a^2=b^2+c^2

If you solve for "a":

a= \sqrt{b^2+c^2}

Where "a" is the hypotenuse and "b" and "c" are the legs.

In this case, for "x" you know that:

a=x\\b=8ft\\c=2ft

Then, the value of "x" is:

x=\sqrt{(8ft)^2+(2ft)^2}\\\\x=8.24ft

For "y" you can see that:

a=10ft\\b=8.24ft\\c=h

Subsituting values and solving for h, you get:

(10ft)^2=(8.24ft)^2+h^2\\\\h=\sqrt{(10ft)^2-(8.24ft)^2} \\\\h=5.66ft
