The biggest key here is identifying outliers. Outliers can pull measures of center either up or down drastically.Notice how the males have a VERY low outlier. This will pull the mean down severely and create a much larger range, or spread.The females have a median of about 12 hours, but have an upper extreme of 19, which compareatively is very high. This creates a larger range as well.
It is still 30\textdegree, no matter how you turn it hope this helps.
The slope intercept form for the first one is y=-3/4x-7, the second is y=-2/5x+2 and these lines are intersecting.
Answer:
-0.4 = −2/5
Step-by-step explanation:
Rewrite the decimal number as a fraction.
-0.4/1
Multiply to remove 1 decimal places.
-0.4/1 x 10/10 =4/10
Find the GCF.
4 ÷ 2/10 ÷ 2 = 2/5
x = 2/5
-2/5
Answer: X=1
Step-by-step explanation:
5x5=(40x) -15
25= 40x -15
-40x=-15-25
-40x=-40 divide by 40 on both sides and you get x = 1
