Answer:
C) 4
Step-by-step explanation:
6. x = 16; it's a scalene triangle
7. x = 45; it's a right triangle.
Answer
k = -1
Step-by-step explanation:
First we turn the equation into y = mx+b format then we we can plug in the value y= 4 and get 4 = -2x + 2
subtract two from both sides so 2= -2x divide btoh sides by 2 and get x = -1
To find median . . . list the number in order from least to greatest
10 , 11, 12, 12 13, 15
Then cross of a number from each side until you get to the middle number or middle 2 numbers.
IF there are 2 numbers add them together and divide by 2
12 + 12 = 24
24 / 2 = 12
Your median is 12
To find mean (this is the same as average) add all the numbers to get a total.
10 + 11 + 12 + 12 + 13 + 15 = 73
Then count the number of items added . . .6
Take the total and divide by the items counted
73 / 6 = 12.1666
Your directions say to round to the nearest tenth place.
12.166 = 12.2
