Answer:

7√3

Step-by-step explanation:

Pythagorean Theorem

a² + b² = c²

7² + b² = 14²

b² = 14² - 7²

b² = 196 - 49

b = √147

7√3

Answer:

AC = 12.12

Step-by-step explanation:

<u>Step 1:  Determine side AC</u>

Pythagorean\ theorem → a^2 + b^2 = c^2

(AC)^2 + (CB)^2 = (AB)^2

(AC)^2 + (7)^2 = (14)^2

(AC)^2 + 49 = 196

<u>Step 2:  Subtract 49 from both sides</u>

(AC)^2 + 49 - 49 = 196- 49

(AC)^2 = 147

<u>Step 3:  Square root both sides</u>

\sqrt{(AC)^2} = \sqrt{147}

AC = 12.12

Answer:  AC = 12.12

Answer:

The answer to your question is 8649 persons

Step-by-step explanation:

Data

Equation              y = 11.89x - 15345.2

Year = x = 2018

Process

Find the mean and the median of this data set: 8, 6, 6, 3, 55, 7, 5, 2. The mean is and the median is .
dexar [7]

Answer:

The mean is 11.5

The median is 6

Step-by-step explanation:

First put all the terms in order from smallest to largest

2, 3, 5, 6, 6, 7, 8, 55

The mean is the average. To figure the mean add all the terms together and divide by the number of terms.

There are 8 terms

2+3+5+6+6+7+8+55=92

92/8=11.5

The median is the middle of all the terms. To figure the median find the middle two terms and find their average.

Hint: If the middle two terms are the same number, the median is that number.

The middle two terms are 6 and 6 so the median is 6
