[Right Triangles Only] Pythagorean Theorem: a² + b² = c²
- a is a leg
- b is another leg
- c is the hypotenuse<u>
</u>
Step-by-step explanation:
<u>Step 1: Identify</u>
Leg a = 24
Leg b = 7 in
Leg c = <em>x</em>
<em />
<u>Step 2: Solve for </u><em><u>x</u></em>
- Substitute in variables [Pythagorean Theorem]: 24² + 7² = x²
- Evaluate exponents: 576 + 49 = x²
- Add: 625 = x²
- [Equality Property] Square root both sides: 25 = x
- Rewrite/Rearrange: x = 25

Let’s divide 48 by 16 to see how many cents per inch of wire. 48/16=3 so it costs 3 cents per inch of wire. now all we have to do is multiply 47 by 3, and you will get 141 cents, or $1.41.
Answer:
Step-by-step explanation:
Use the normcdf( function on a basic calculator as follows:
normcdf(-1000, 9750, 12000, 4500). Result: 0.307. This is the area under the standard normal curve to the left of 9750.
But we want the area under the standard normal curve to the right of 9750, so we subtract this 0.307 from 1.000, obtaining the desired result: 0.693. This roughly corresponds with the last of the given possible answers, 69.15%.
