If 2.3% of tomatoes produced at a farm are considered to be small and cannot be sold for commercial purposes, and 12 are chosen randomly (mean of 3 cm and SD of 0.5 cm) tomatoes that are large will be larger than 2.5 cm. what portion is large?

And if 12 tomatoes are randomly selected from the produce calculate;

a) the probability that three are not fit for selling

b) the probability that at least four are not fit for selling

the solution is the point

step-by-step explanation:

we have

> equation a

> equation b

adds equation a and equation b

substitute the value of x in equation b to find the value of y

the solution is the point

- "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."
