2) $0.65 per minute
y-intercept is the fixed amount which must be paid regardless of how much time internet is used
1) $5
2) $7
Answer:
0.267
Step-by-step explanation:
This can be solved using the binomial probability formula which is:
Where
n is total number of trials (here, the total number of questions is 8, so n = 8)
k is the number of attempts we are looking for (here, we want to find probability of 1 question correct, so k = 1)
p is the probability of success (here, success is getting a questions right. Since there are 4 choices and 1 is right, probability of right = 1/4)
<em>Plugging all the info into the formula we get:</em>

<em>Second choice is right.</em>
Answer:
B. 0.0625
Step-by-step explanation:
Given that the program has graduated and undergraduates enrolled,
Let the probability of selecting a graduate = p(g)
And the probability of selecting an undergraduate = p(u)
p(g) = p(u) = 50% = 0.5
Therefore,
Probability of selecting 4 students who are undergraduates
=p(u)p(u)p(u)p(u)
= 0.5 × 0.5 × 0.5 × 0.5
= 0.0625
The right option is B
Answer:
9
Step-by-step explanation:
Range is just the difference between the highest and lowest number. So, in this case it should be 10 - 1.
