Answer:
The probability that the number of free throws he makes exceeds 80 is approximately 0.50
Step-by-step explanation:
According to the given data we have the following:
P(Make a Throw) = 0.80%
n=100
Binomial distribution:
mean: np = 0.80*100= 80
hence, standard deviation=√np(1-p)=√80*0.20=4
Therefore, to calculate the probability that the number of free throws he makes exceeds 80 we would have to make the following calculation:
P(X>80)= 1- P(X<80)
You could calculate this value via a normal distributionapproximation:
P(Z<(80-80)/4)=1-P(Z<0)=1-50=0.50
The probability that the number of free throws he makes exceeds 80 is approximately 0.50
He has six pieces ribbon and one little piece that is 0.2 meters long
Step-by-step explanation:
This is called a back bearing
when the given angle is less than 180, then the back bearing is= the given angle + 180
34+180=214°
Answer:
EDIT:
10 feet for every second
Step-by-step explanation:
Find a dotted point
Locate the x and y, or attitude and seconds in. This case
So we know 60 ft in 3 seconds
So we know the slope is one so go down 1 right 1
That would put us at another point that is not dotted but its on the graph
So its 50 feet in 4 sec
So we know its 10 feet per sec
