1 answer:
vfiekz [6]3 years ago
7 0

Answer:

8

Step-by-step explanation:

You use law of sines, and get: AB/sin(53) = 7/sin(44)

You multiply both sides by sin(53), and get:

AB = 7*sin(53)/sin(44)

That means AB is 8.04776679886, which rounds to 8

What’s the correct answer for this?
Pavlova-9 [17]

Answer: choice B

Step-by-step explanation:

Events A and B are independent if the equation P(B)=P(B|A) or P(A∩B) = P(A) · P(B) holds true.

in this example

p(A)=1/6    {5}

p(B)=1/2   {1,3,5}

P(B|A)=1

so

P(B)≠P(B|A)

=>A and B are dependent

Hello from MrBillDoesMath!

Answer:

y = x/15


Discussion:

Given:

2x/5y = 6  =>          (multiply both sides by 5y)

(2x/5y) 5y = 6 * (5y) =>

2x = 30y =>            (divide both sides by 30)

(2/30)x = y =>

y = x/15


( or you could also multiply both sides of the original equation by "y" and then divide both sides by 6)

Thank you,

MrB

5 pounds of bananas for $1.97 for 3 pounds of bananas for $1.05 which is better to buy
andrew11 [14]

Answer:

<h3>3 pounds for $1.05 is better since it is 35 cents a pound as opposed to 39 cents a pound for the other product.</h3>

Step-by-step explanation:

We need to find the unit rate. This found by dividing the price by the number of bananas so we get the price for 1 pound of bananas.

$1.97/5 = $0.39

$1.05/3 = $0.35

<h3>3 pounds for $1.05 is better since it is 35 cents a pound as opposed to 39 cents a pound for the other product.</h3>
