A small college has 800 students, 10% of which are left-handed. Suppose they take an SRS of 30 students. Let X= the number of left-handed students in the sample. What is the probability that more than 7 of the 30 students are left-handed?

17   x 256=4352

sorry if this is wrong, i'm new.

step-by-step explanation:

the answer is (-4,-4)

hope this ! : d

- "runner b is moving at a slower rate."

- "the graphs shown are graphs of distance(km) against time(min).

the slopes of this graphs are are given by:

slope = (change in y)/(change in x)

= (change in distance)/(change in time)

this is the formula for finding the speed. so, the slope of these graphs represent the speed of the runner.

taking each division in the graph to represent 1 on both axis:

runner a ⇒ speed = (2-0)/(1-0)

= 2/1

= 2 km/min

runner b ⇒ speed = (3-0)/(3-0)

= 3/3

= 1 km/min

this shows that   runner b is moving at a slower rate."
