The mean song length on Jacks 3 minutes and 3 seconds , with a Standard deviation of 24 seconds. Find the probability that the next song to play is no more than 3 minutes and 45 seconds.

0.9599

Step-by-step explanation:

First, convert the times to seconds.

3 min 3 sec = 183 sec

3 min 45 sec = 225 sec

Next, find the z-score.

z = (x − μ) / σ

z = (225 − 183) / 24

z = 1.75

Next, use a calculator or z score table to find the probability.

P(Z < 1.75) = 0.9599

a = 11 : 4

b = 38

c = 1 for every 6

step-by-step explanation:

i think something is missing in your question because y-1=(x-12) would not pass through the point (-4,-3). because if you replace x by -4 your are supposed to find y=-3 which is not the case her. if you replace x by -4 you find =-15.

i assume the right equation is y-1=1/4*(x-12) because this one is passing through both your points (if you are interested to know how i found that out i can tell you).

in this equation if i replace x by -4 i find y=-3 and if i replace x by 12, i find y=1 so the line representing this equation is passing through those 2 points.

then the standard form of the equation is finding an expression of y in function of x

y-1=1/4*(x-12)

y=x/4-3+1

y=x/4-2

hope that .

do you confirm there was a mistake in the question?
