Lewis needed to find the difference in lengths between the hypotenuse and the longest leg of this triangle. His work is shown be

low. Triangle A B C. Side B C is 16 and side A C is 12. Hypotenuse A B is labeled c. 12 squared + 16 squared = c squared. 144 + 256 = c squared. 400 = c squared. StartRoot 400 EndRoot = c. 200 = c. Difference: 200 minus 12 = 188. What errors did Lewis make? Check all that apply. He simplified StartRoot 400 EndRoot incorrectly. It should be 20 instead of 200. He found the difference between the hypotenuse and the short leg instead of the long leg. He evaluated 12 squared incorrectly. It should be 12 (2) = 24. He evaluated 16 squared incorrectly. It should be 16 (2) = 32. He should not have taken the square root of each side to get rid of the exponent.

According to a National Health Survey, American men’s heights are normally distributed with a mean given by μ=69.7 inches and a
Novay_Z [31]

Answer: 0.206

Step-by-step explanation:

Given that :

Height of American men is normally distributed :

Mean height (μ) = 69.7 inch

Standard deviation (σ) = 2.8 inch

Probability that height of a randomly selected man is more than 72 inches

P(X > 72)

Obtain the standardized score (Zscore):

Zscore = (x - μ) / σ

Zscore = (72 - 69.7) / 2.8

Zscore = 2.3 / 2.8

Zscore = 0.8214285

Zscore = 0.8214

Using the Z probability calculator ;

P(Z > 0.8214) = 0.20571

Probability of selecting a man whose height is more Than 72 is 0.206

Step2247 [10]

Answer:

option D

\frac{8}{3} + \sqrt{\frac{-7}{3} }

Step-by-step explanation:

Given in the question are 4 number

5√1/3 - \frac{9}{\sqrt{7} }

2 - \frac{1}{\sqrt{11} }

9 + 3\sqrt{\frac{5}{2} }

\frac{8}{3} + \sqrt{\frac{-7}{3} }

A Complex Number is a combination of a Real Number and an Imaginary Number

<h3>Example </h3>

a + ib

where a is real number

            b is imaginary number

            i is 'lota' which is √-1

<h3>So according to the definition above </h3>

\frac{8}{3} + \sqrt{\frac{-7}{3} } is complex number in which

\frac{8}{3} is real part

\sqrt{\frac{7}{3} } \sqrt{-1} = \sqrt{\frac{7}{3} } i is the imaginary part

The figures below are similar. The labeled sides are corresponding.
aev [14]

Answer: 24 cm

Step-by-step explanation:

P_{square} = side *4

It is multiplied by 4 because a square has 4 equal sides and 4 equal angles.

P = 6 * 4 = 24
