Answer:

0.0499

Step-by-step explanation:

This is a binomial probability function expressed as:

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

Given that n =8, and p(male)=1-0.6=0.4, the probability of at least 6 being male is calculated as:

$P(X=x)={n\choose x}p^x(1-p)^{n-x}\\\\P(X\geq 6)=P(X=6)+P(X=7)+P(X=8)\\\\={8\choose 6}0.4^6(0.6)^{2}+{8\choose 7}0.4^7(0.6)^{1}+{8\choose 8}0.4^8(0.6)^{0}\\\\=0.0413+0.0079+0.0007\\\\=0.0499$

Hence, the probability of at least 6 males is 0.0499

Courtney is ordering nachos at a restaurant, and the server tells her that she can have up to three toppings: pico de gallo, oni

aalyn [17]

Answer:

$Probability = \frac{1}{9}$

Step-by-step explanation:

Given

Toppings: Pico de gallo, Onions and Steak

Required

The probability of getting Onions and Steak

The probability is calculated using:

$Probability = P(Onion)\ and\ P(Steak)$ --- because the events are independent

$P(Onion) = \frac{n(Onion)}{Total}$

$P(Onion) = \frac{1}{3}$

$P(Steak) = \frac{n(Steak)}{Total}$

$P(Steak) = \frac{1}{3}$

So, we have:

$Probability = P(Onion)\ and\ P(Steak)$

$Probability = P(Onion)\ *\ P(Steak)$

$Probability = \frac{1}{3} * \frac{1}{3}$

$Probability = \frac{1}{9}$

Use point-slope form to write the equation of a line that passes through the point

blagie [28]

Answer:

y - 8 = -2(x - 9)

Step-by-step explanation:

Given the slope, m = -2, and the point, (9, 8):

Let (x₁, y₁) = (9, 8)

slope (<em>m </em>) = -2

We can substitute these values into the following <u>point-slope form</u>:

y - y₁ = m(x - x₁)

y - 8 = -2(x - 9) ⇒ This is the point-slope form.
