Answer:
the probability that out of these 75 people, 14 or more drink coffee is 0.6133
Step-by-step explanation:
Given that:
sample size n = 75
proportion of high school students that drink coffee p = 20% = 0.20
The proportion of the students that did not drink coffee = 1 - p
Let X be the random variable that follows a normal distribution
X N (n, p)
X N (75, 0.20)
= 75 × 0.20
15
Now ; if 14 or more people drank coffee ; then
From the standard normal z tables; (-0.288)
the probability that out of these 75 people, 14 or more drink coffee is 0.6133
We know that
360°/12 hour-----------> 30°/hour
<span>Central angle at 4 .00 is 120 degrees
the radius of a clock is 6/2-----> r=3 in
length of a circumference=2*pi*r-----> 2*pi*3----> 18.84 in
the minor arc at 4 .00 is for a central angle of 120</span>°
so
if 360° (full circle)---------> has a length of 18.84 in
120°----------------------> X
X=120*18.84/360-------> X=6.28 in
the answer is
6.28 in
