Hi, Hayesannaliese! There are two ways of solving this.

For right triangles, we can use the Pythagorean theorem. For this, we can see that (-2, 5) is 9 units above (-2, -4) and (6, 5) is 8 units right of (-2, 5). For the Pythagorean theorem, a^2 + b^2 = c^2. Plug in the a and b values below:

(8)^2 + (9)^2 = c^2

--> 64 + 81 = c^2

---> 145 = c^2

----> \sqrt{145} = c

c = 12.04 units


Second method: finding the distance between two points

\sqrt{(x2 - x1)^2 + (y2 - y1)^2}

For this problem, we need to find the distance between (-2, -4) and (6, 5).

So the equation is \sqrt{(6 - (-2))^2 + (5 - (-4))^2}

--> \sqrt{8^2 + 9^2}

---> \sqrt{64 + 81}

----> \sqrt{145}

= 12.04 units.

Hope this was helpful. Good luck. :)

Apply Pythagorean:
Hypotenuse^2 = 8^2 + 9^2
Hypotenuse = sqrt ( 64+81)
Hypotenuse = sqrt 145
Hypotenuse ~ 12.04

Solve for x, 12y+6=6(y+1)
Vanyuwa [196]

For this case we must solve the following equation:

12y + 6 = 6 (y + 1)

We apply distributive property on the right side of the equation:

12y + 6 = 6y + 6

We subtract 6y on both sides of the equation:

12y-6y + 6 = 6\\6y + 6 = 6

We subtract 6 from both sides of the equation:

6y = 6-6\\6y = 0

Dividing by 6 on both sides of the equation:

y = 0

So, the result is y = 0

Answer:

y = 0

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
