A researcher wishes to conduct a study of the color preferences of new car buyers. Suppose that 50% of this population prefers t
ehidna [41]

Answer:

The probability that more than a third of the buyers would prefer brown is 0.8491.

Step-by-step explanation:

This is binomial problem with n=15 and p=0.50.

The binomial formula of probaility is:

P(X=x)=\frac{n!}{x!(n-x)!} p^{x} (1-p)^{n-x}

More than a third of the buyers: 15÷3=5

We have to find P(x>5).

P(x>5) = 1 - P(x≤5) = 1 - P(x=0) - P(x=1) - P(x=2) - P(x=3) - P(x=4) - P(x=5)

P(x=0)=\frac{15!}{0!15!} (0.5)^{0} (1-0.5)^{15}=0.00003

P(x=1)=\frac{15!}{1!14!} (0.5)^{1} (1-0.5)^{14}=0.00046

P(x=2)=\frac{15!}{2!13!} (0.5)^{2} (1-0.5)^{13}=0.00320

P(x=3)=\frac{15!}{3!12!} (0.5)^{3} (1-0.5)^{12}=0.01389

P(x=4)=\frac{15!}{4!11!} (0.5)^{4} (1-0.5)^{11}=0.04165

P(x=5)=\frac{15!}{5!10!} (0.5)^{5} (1-0.5)^{10}=0.09164

P(x>5) = 1 - P(x≤5)= 1- 0.00003 - 0.00046 - 0.00320 - 0.01389 - 0.04165 - 0.09164 = 0.8491

Answer:

  • y-intercept: (0, 3)
  • axis of symmetry: x = -1

Step-by-step explanation:

The y-intercept is the constant, 3. It is the value of f(0).

__

The axis of symmetry of  the quadratic function ...

  f(x) = ax^2 +bx +c

is ...

  x = -b/(2a)

Here, using that formula gives ...

  x = -(2a)/(2(a)) = -1

The axis of symmetry is x = -1.

What is the quotient of 3 ÷ 2 1/3, reduced to lowest terms?\
Arisa [49]

Answer:

\frac{9}{7}

Step-by-step explanation:

3 ÷ 2 1/3

2 1/3 can be written as \frac{2*3+1}{3} =\frac{7}{3}

Now we divide 3 by 7/3

\frac{3}{\frac{7}{3}}

Now we flip the fraction 7/3  and  multiply with 3

3*\frac{3}{7}

\frac{9}{7}

We cannot simplify it

So 9/7 is the final answer
