Two urns each contain green balls and blue balls. Urn I contains 4 green balls and 6 blue balls, and Urn II contains 6 green balls and 2 blue balls. A ball is drawn at random from each urn. What is the probability that both balls are blue?A. 2/51


B. 3/20


C. 1/10



D.4/153

Answers

Answer 1
Answer:

Answer: B. (3)/(20)


Step-by-step explanation:

Let A be the event that a blue ball is drawn from urn l and let B be the event that a blue ball is drawn from urn ll.

Then P(A)=\frac{\text{number of blue balls}}{\text{total balls}}

=(6)/(10)=(3)/(5)

and P(B)=\frac{\text{number of blue balls}}{\text{total balls}}

=(2)/(8)=(1)/(4)

As both the events are independent, thus the probability that both balls are blue =P(A)*\ P(B)=(3)/(5)*(1)/(4)=(3)/(20)

You are a contractor who is installing new windows. You are working on a house that has 6 windows that are each 3 feet by 4 feet.If the glass for the windows costs $0.05 per square inch, approximately how much money will the glass cost for all of the window installations?

A.
$36
B.
$43
C.
$432
D.
$518

Answers

Answer:

D. $518

Step-by-step explanation:

We know that the windows are 3ft by 4ft, find the area:

A = L * W

A = 3ft * 4ft

A = 12 sq ft

12 sq ft is the area of each window in the house

Now multiply the amount of windows in the house by the 12 sqft:

12 sqft * 6

72 sq ft

The combined area of all 6 windows are 72 sqft. Now since 1 sqft is equal to 144 sq inches, simply convert the square feet into squared inches:

72 * 144

10,368 squared inches

Since each square inch costs 0.05 cents, multiply the amount of square inches by the cost of each square inch:

0.05 * 10,368

$518.4

Since D. is the closest value, that would be our answer.

Answers:

x = 141

y = 39

Explanation

Angle x and angle 141 are congruent because they are corresponding angles, and because the lines are parallel. Corresponding angles are in the same corner. In this case it's the northwest corner.

Angles x and y are supplementary. They glue together to get a straight line. Which means the angles add to 180.

x+y = 180

141+y = 180

y = 180-141

y = 39
