Answer: 8 fewer students
Step-by-step explanation:
Drums - 32
Trombone - 16
Flute - 40
32 + 16 = 48
48 - 40 = 8
Hope it helps!
Answer:
Mean is 19.43
Standard deviation is 2.5322
Step-by-step explanation:
For each student who graduated from high school in 2012, there are only two possible outcomes. Either they have enrolled in college, or they have not. The probability of a student having enrolled in college is independent of other students. So we use the binomial probability distribution to solve this question.
Binomial probability distribution
Probability of exactly x sucesses on n repeated trials, with p probability.
The expected value of the binomial distribution is:
The standard deviation of the binomial distribution is:
67% of students who graduated from high school in 2012 enrolled in college.
This means that
Sample of 29 high school graduates
This means that
Mean
Standard deviation
Answer:
Solve for x by simplifying both sides of the equation, then isolating the variable.
x=132,−118

I cant see the picture? could you maybe try again?
Answer:
y = + 5
Step-by-step explanation:
Find the slope of MN, which is
Then, use the formula: y-y₁ = m(x-x₁)
Use point P as (x₁, y₁)
Plugging in x₁ = 6 and y₁ = 1 and simplifying, we find that:
y - 1 = (x - 6)
Simplify to find that:
y = + 4 + 1
y = + 5
