A study conducted at a certain high school shows that 72% of its graduates enroll at a college. Find the probability that among

mixas84 [53]

Answer:

$P(X \geq 1) =1-P(X$

And we can use the probability mass function and we got:

$P(X=0)=(4C0)(0.72)^0 (1-0.72)^{4-0}=0.00615$

And replacing we got:

$P(X \geq 1) = 1-0.00615 = 0.99385$

Step-by-step explanation:

Let X the random variable of interest "number of graduates who enroll in college", on this case we now that:

$X \sim Binom(n=4, p=0.72)$

The probability mass function for the Binomial distribution is given as:

$P(X)=(nCx)(p)^x (1-p)^{n-x}$

Where (nCx) means combinatory and it's given by this formula:

$nCx=\frac{n!}{(n-x)! x!}$

We want to find the following probability:

$P(X \geq 1)$

And we can use the complement rule and we got:

$P(X \geq 1) =1-P(X$

And we can use the probability mass function and we got:

$P(X=0)=(4C0)(0.72)^0 (1-0.72)^{4-0}=0.00615$

And replacing we got:

$P(X \geq 1) = 1-0.00615 = 0.99385$

Gala2k [10]

Answer:

B 11,000,000

Step-by-step explanation:

Commission was 10 percent, 10 percent of 10,000,000 is 1,000,000, therefore add 1,000,000 to 10,000,000, which equals to 11,000,000

Actual price of house after commission= B 11,000,000

Which expressions are equivalent to -6 +49 +(-6q)?<br> Choose all answers that apply:

Sidana [21]

Answer:

C, none of them are equivalent

BECAUSE

For A, the -4q should be positive 4q to apply

For B, the 2q when distributing with the parentheses should be negative 2q to work with the expression above
