(-3,7)(9,5)

midpoint formula : (x1 + x2)/2 , (y1 + y1)/2

(-3 + 9)/2 , (7 + 5)/2 = (6/2, 12/2) = (3,6) <==

Here's the question

zheka24 [161]

Answer:

Step-by-step explanation:

perimeter (p) = 8 + 17 + 15 = 40

semi-perimeter (s) = p/2 = 20

Area = square root of s(s-a)(s-b)(s-c) where a,b,c are the sides of the triange by Herons formula.

Therefore, area = 20(20-8)(20-15)(20-17) = square root of 3600 = 60

A normal distribution has a mean 20 and standard deviation 5. What is the z score that corresponds to the value x=222

sashaice [31]

Answer: The z score that corresponds to the value x=22 is 0.4 .

Step-by-step explanation:

Given : A normal distribution has a mean 20 and standard deviation 5.

i.e. $\mu=20$

$\sigma=5$

Let x be the random selected variable.

We know that to find the z-score corresponds to the value x is given by :-

$z=\dfrac{x-\mu}{\sigma}$

For x = 22, we have

$z=\dfrac{22-20}{5}=\dfrac{2}{5}\\\\\Rightarrow\ z=0.4$

Hence, the z score that corresponds to the value x=22 is 0.4

1 x 1 = 1
1 x -5 = -5

jasenka [17]

Answer:

x = -2

Step-by-step explanation:

2(4x+8)

= 8x+16

8x+16 = 0

-16 -16

8x = -16 (do -16÷8 & get)

x = -2
