Z = ( X - Mean ) / SD
z = ( 646 - 597 ) / 39
z = 49/39 = 1.25
With the z-score table:
for z = 1.25, p = 0.8944 ( probability that the cost will be lower than $646 )
1 - 0.8944 = 0.1056
Answer: <span>The probabilit</span>y is 0.1056

Paul sketched a right angel with legs of length a, b, and h. Then he writes an expression for the length of the hypotensure. Wha

MA_775_DIABLO [31]

Answer:

Paul might have written the expression $h^2=a^2+b^2$ .

Step-by-step explanation:

Given:

Length of the leg 1 = a

Length of the leg 2 = b

Hypotenuse = h

We need the expression Paul has written:

Solution:

Now we know that;

The figure sketched by Paul is a right angle triangle.

Now by Pythagoras Theorem which states that;

"The square of the length of the hypotenuse is equal to sum of the square of the length of the legs."

equation can be framed as;

$h^2=a^2+b^2$

Hence Paul might have written the expression $h^2=a^2+b^2$ .
