Answer:
a) The probability that exactly 17 of them enroll in college is 0.116.
b) The probability that more than 14 enroll in college is 0.995.
c) The probability that fewer than 11 enroll in college is 0.001.
d) It would be be unusual if more than 24 of them enroll in college since the probability is 0.009.
Step-by-step explanation:
We can model this with a binomial distribution, with n=29 and p=0.65.
The probability that k students from the sample who graduated from high school in 2012 enrolled in college is:

a) The probability that exactly 17 of them enroll in college is:

b) The probability that more than 14 of them enroll in college is:

c) Using the probabilities calculated in the point b, we have:

d) The probabilities that more than 24 enroll in college is:

Step-by-step explanation:
The distance from the surfer to the shoreline will be found as follows:
tan θ= opposite/adjacent
θ=10°
opposite=7ft
adjacent= x ft
substituting the values in our formula and solving for x we get
tan 10=7/x
hence
x=7/tan10
x=39.69897~ 39.7 ft
The surfer is 39.7 ft from the shoreline.
Answer:
10 visors
Step-by-step explanation:
Make an equation
Each visor, v costs $6, and there is a $5 fee regardless of the amount of visors purchased. This must be equal to $65
6v+5=65
Now, solve for v
Subtract 5 from both sides
6v=60
Divide both sides by 6
v=10
You can buy 10 visors
Answer:
Step-by-step explanation: First find angle 2. 180-59= 121 angle 1 and 2 are equal so their sum must be
242
Graph needs to be labeled. I labeled it as shown on picture. It also needs a title. The title can be up to you. :) you can title it “Karen riding her bike”
