Answer:
-3
Step-by-step explanation:
We have two points
( -3,1) ( -1,-5)
We can use the slope formula
m = (y2-y1)/(x2-x1)
= ( -5-1)/(-1- -3)
= (-5-1) / (-1+3)
= -6/2
= -3
4.23 + 16.21 = 20.44 (C)
42.3 + 1.621 = 43.921 (D)
4.23 - 1.621 = 2.609 (B)
42.3 - 16.21 = 26.09 (A)
Hope this helps :)
Answer: 35x+3
Step-by-step explanation:
Answer:
The base is 11 cm.
Step-by-step explanation:
The formula for the area of a triangle is 
. If we plug in what we know to this equation, we are left with 
, which we now need to simplify.
First, we combine like terms.
Then, we can eliminate the 
and 
on the right side of the equation, since they cancel each other out.
Finally, we take the square root of both sides of the equation and find our answer:
Put the numbers in order.
1, 2, 5, 6, 7, 9, 12, 15, 18, 19, 27.
Step 2: Find the median.
1, 2, 5, 6, 7, 9, 12, 15, 18, 19, 27.
Step 3: Place parentheses around the numbers above and below the median.
Not necessary statistically, but it makes Q1 and Q3 easier to spot.
(1, 2, 5, 6, 7), 9, (12, 15, 18, 19, 27).
Step 4: Find Q1 and Q3
Think of Q1 as a median in the lower half of the data and think of Q3 as a median for the upper half of data.
(1, 2, 5, 6, 7), 9, ( 12, 15, 18, 19, 27). Q1 = 5 and Q3 = 18.
Step 5: Subtract Q1 from Q3 to find the interquartile range.
18 – 5 = 13.
