Answer:
69
Step-by-step explanation:
Here, we are interested in getting the median of the distribution
Mathematically, if we are talking about a moral distribution, we have equal values for median, mode and mean
Hence the median in this case will be 69
Answer:
4/7
Step-by-step explanation:
5/7 x (1/5+3/5) = 5/7 x 4/5 = 4/7
Answer:
D 70/3
Step-by-step explanation:
5 /3 * 2/3 * 21
10/9 * 21/1
210/9
We can divide by 3 on the top and bottom
70/3
Inverse variation is of the form yx=k, we are given the point (0.2, 100) so we can solve for k, the constant of variation...
0.2(100)=k
20=k
y=-2x+14
Step-by-step explanation:
use point slope
y-y1=m(x-x1)
and m= <u>y2-y1</u><u> </u>
x2-x1
m= <u>4</u><u>-</u><u>2</u>
5-6
m=2/-1
then use the 1st formula to plug everything in
y-2=-2(x-6)
then distribute the 2 on the right side
y-2=-2x-2×-6
-2×-6 is 12 since a negative times a negative is positive
y-2=-2x+12
then to get y alone we have to get everything on the right side of the = sign, so the opposite of subtraction is addition, lets add 2 to the right
y-2=-2x+12
+2. +2
y=-2x+14
