Step-by-step explanation:

-4 x 0.3 = -1.2

f(0.3) = -1.2 -6

Suppose that you are taking a T/F exam and you have no idea at all about the answers to the last three questions. You choose ans

podryga [215]

Answer:

0.375, 0.125, 0.5

Step-by-step explanation:

given that you are taking a T/F exam and you have no idea at all about the answers to the last three questions.

Probability for correct guess = 0.5 remains constant for each of the three questions

X - no of questions is binomial with n =3 and p = 0.5

1) the probability that you guessed right on exactly one of the three questions

= P(X=1)

= $3C1(0.5)^3 = 0.375$

2) the probability that you guessed right on zero of the three questions

= $P(X=0)\\= 0.5^3=0.125$

3) the probability that you guessed right on at least two of the questions

= $P(x=3)+P(2)\\= 1-0.5\\=0.5$

The number of visitors to a certain Web site triples every month. The number of visitors is modeled by the expression 900 * 3^m

kipiarov [429]

Answer:

$900\times 3^m$ = 100

Step-by-step explanation:

The number of visitors is modeled by the expression $900\times 3^m$

Where m is the number of months after the number of visitors was measured.

We need to evaluate the above expression for m = -2.

So,

$900\times 3^m=900\times 3^{-2}\\\\=900\times \dfrac{1}{3^2}\\\\=900\times \dfrac{1}{9}\\\\=100$

At m = -2, the value of the above expression is equal to 100.
