Answer:

The answer is \sqrt{20}.

Step-by-step explanation:

Use the Pythagorean Theorem.  

2^{2} + 4^{2} = c^{2} \\4+16 = c^{2} \\\sqrt{20} = c

<h3>Answer: sqrt(20)</h3>

=========================================

Explanation:

Count out the spaces, or use subtraction, to find the horizontal side BC is 2 units long. Similarly, you'll find the vertical side AC is 4 units long.

Use the pythagorean theorem to find the length of segment AB.

a^2 + b^2 = c^2

2^2 + 4^2 = c^2

4 + 16 = c^2

20 = c^2

c^2 = 20

c = sqrt(20)

We stop here since it matches with choice B.

-----------------

Optionally, we can simplify like so

sqrt(20) = sqrt(4*5)

sqrt(20) = sqrt(4)*sqrt(5)

sqrt(20) = 2*sqrt(5)

The average age of all students at a certain college is 22 years and the standard deviation is 2 years. What is the probability
Marianna [84]

Answer:

The probability that the average age of a randomly selected sample of 100 students will be less than 21.8 years is 0.159

Step-by-step explanation:

According to the given data we have the following:

mean = μ= 22

standard deviation = σ = 2

n = 100

μx = 22

σx=σ/√n=2/√100=0.2

Therefore, P( x < 21.8)=P(x-μx)/σx<(21.8-22)/0.2

=P(z<-1)

= 0.159

The probability that the average age of a randomly selected sample of 100 students will be less than 21.8 years is 0.159

A line passes through the points(-9,9) and has a slope of 2/3​
Anni [7]
ANSWER

y = 2/3x + 15

Explanation:

Equation used: y - y1 = m( x - x1 )

y - 9 = 2/3 ( x - -9 )

y - 9 = 2/3x + 6 ( distribution )

y - 9 = 2/3x + 6 ( add 9 to 6 )

y = 2/3x + 15
