Answer:
D) He calculated the joint relative frequency of female students who prefer playing sports. The conditional relative frequency for female students who prefer playing sports is 34%.
Step-by-step explanation:
The table is given as:
Playing sports Dancing Row totals
Male students 18 16 34
Female students 18 35 53
Column totals 36 51 87
- We know that the joint relative frequency of an outcome is calculated as dividing the frequency of the outcome by the grand total.
Hence, when we divide the frequency of the female students who prefer playing sports i.e. 18 by the grand total i.e. 87 ; we obtain:
18/87=0.20689
which is approximately equal to 21%.
- Hence, in order to calculate the conditional relative frequencies she should have divided the required frequency by the row total;.
Hence, here we divide the frequency of the female students who prefer playing sports i.e. 18 by the row total i.e. 53 ; we obtain:
18/53-0.3396
which is approximately equal to 34%.
Hence, option: D is correct.
I need a picture or an example to help you. To identify the slope and y-intercept you have to do slope intercept form. Y=mx+ b or y=slope+ y intercept. If you are looking at a graph then, the y intercept is the only point on the y axis. To find the slope on a graph you have to count how much the point rises and moves from each point. Like, if my point was (1,3) and the next point was (3,4). To get to (3,4) you would have to go up 1 and move 3 spaces to the right. Your slope would be 1/3.

Answer:
12 cm of coastline
Step-by-step explanation:
Multiply the years (factor) by the receding amount, 3cm, (constant) BAM answer.
That would be 16(1/4)^(n-1)
for example 4th term = 16(1/4)^3 = 1/4
