If a fish swims 7/8 of the depth of a 32-foot deep lake, how many feet down did the fish swim?
Arlecino [84]
8/8 would be 32 so 7/8 would be 28 because 8 x 4 = 32 which would make each eight equal four.

MissTica

Answer:

(b) 6.25%

Step-by-step explanation:

Margin of error is the chances of percentage deviation that may differ from original population data. The margin of error for 95% confidence interval can be 6.25%. To find this we divide population standard deviation with square root of sample size. The margin of error is the estimate of the deviation from actual and real value of population.

  • [Right Triangles Only]: Pythagorean Theorem: a² + b² = c²

Step-by-step explanation:

<u>Step 1: Define</u>

We are given a right triangle. We can use PT to solve for the missing length.

<u>Step 2: Identify Variables</u>

Leg <em>a</em> = 8

Leg <em>b</em> = 8

Hypotenuse <em>c</em> = <em>x</em>

<u>Step 3: Solve for </u><em><u>x</u></em>

  1. Substitute [PT]:                    8² + 8² = x²
  2. Exponents:                           64 + 64 = x²
  3. Add:                                      128 = x²
  4. Isolate <em>x</em>:                               8√2 = x
  5. Rewrite:                                x = 8√2

What is the value of f(7.5) when f(x)=2x+7
Ivan

Hey there!!

Given :

f ( x ) = 2x + 7

Find f ( 7.5 )

Now, we will need to substitute the value of 7.5 in place of x

f(7.5) = 2(7.5) + 7

f(7.5) = 15 + 7

f(7.5) = 22

Hope my answer helps!
