Ed signed up for a weight-loss program. The table shows his weight in pounds of the terms of the number of weeks since he began
il63 [147K]
Ed : (0,205)(4,197)
slope(m) = (197 - 205) / (4 - 0) = -8/4 = -2

y = mx + b
slope(m) = -2
(0,205)...x = 0 and y = 205
time to sub
205 = -2(0) + b
205 = b
equation is : y = -2x + 205...so Ed loses 2 lbs per week

Eric :
y = -1.5x + 200...so Eric loses 1.5 lbs per week

when they started, Ed weighed 205 lbs and Eric weighed 200 lbs

* of the two, Eric loses fewer lbs per week. When the two began their respective weight-loss programs, Ed was heavier by 5 lbs.

If 54% of all people between the ages of 35 and 50 ride a bike, find the probability for a sample of 30 people in that age group
Yuliya22 [10]

Answer:

The probability is 0.1312

Step-by-step explanation:

Here, let us set up a binomial system

From the question, 54% ride a bike

Let p = people that rides a bike

54% = 54/100 = 0.54

p = 0.54

q = 1 - p = 1 -0.54 = 0.46 ( 46% do not ride bikes)

Now, for the binomial system, we have

P(X = 15) = 30 C 15 • p^15•q^15

We have;

30 C 15 * 0.54^15 * 0.46^15

= 0.131200268998

The probability is 0.1312
