Answer:

7\sqrt{3} or 12.12

Step-by-step explanation:

The pythagorean theorem states that <em>a</em>^2 + <em>b</em>^2 = <em>c</em>^2, with<em> a</em> and <em>b</em> representing the legs and <em>c</em> representing the hypotenuse.

7^2 + x^2 = 14^2

49 + x^2 = 196

x^2 = 147

x = 7\sqrt{3} or 12.12

Answer:

x = sqrt(147)

Step-by-step explanation:

This is a right triangle, so we can use the Pythagorean theorem.

a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse.

x^2 +7^2 = 14^2

x^2 +49 = 196

Subtract 49 from each side

x^2 = 147

Take the square root of each side

sqrt(x^2) = sqrt(147)

x = sqrt(147)

1. The total area within any continuous probability distribution is equal to 1.00.
olchik [2.2K]

Answer:

1. True

2. False.

3. True.

Step-by-step explanation:

1. The total area within any continuous probability distribution is equal to 1.00: it is true because the maximum probability (value) is one (1), therefore, the total (maximum) area is also one (1).

<em>Hence, for continuous probability distribution: probability = area</em>.

2. For any continuous probability distribution, the probability, P(x), of any value of the random variable, X, can be computed: False because it has an infinite number of possible values, which can not be counted or uncountable.

<em>Hence, it cannot be computed. </em>

3. For any discrete probability distribution, the probability, P(x), of any value of the random variable, X, can be computed: True because it has a finite number of possible values, which are countable or can be counted.

<em>Hence, it can be computed. </em>

A town has a population of 20000 and grows at 4% every year. What will be the population after 6 years, to the nearest whole num
zaharov [31]

Answer:

25306

Step-by-step explanation:

a=starting value = 20000

r=\text{rate = }4\% = 0.04

r=rate = 4%=0.04

\text{Exponential Growth:}

Exponential Growth:

b=1+r=1+0.04=1.04

b=1+r=1+0.04=1.04

\text{Write Exponential Function:}

Write Exponential Function:

y=20000(1.04)^x

y=20000(1.04)  

x

 

Put it all together

\text{Plug in time for x:}

Plug in time for x:

y=20000(1.04)^{6}

y=20000(1.04)  

6

 

y= 25306.38037

y=25306.38037
