Sounds like a multiple choice question.

A parallelogram is a quadrilateral, except all 4 sides are parallel, unlike a rhombus, which is also a quadrilateral. In a parallelogram, all the sides can be the same length, such as a square, or you can have two sides with the same length, and two other sides with the same length. As long as you have 2 sets of parallel lines, it's a parallelogram.

A certain game involves tossing 3 fair coins, and it pays .14 for 3 heads, .06 for 2 heads, and .01 for 1 head. The expected win

Romashka [77]

Answer:

Total expected amount = $0.04375

Step-by-step explanation:

We need to calculate probability of getting heads on every combination of coin tosses

HHH = 1/8 = 3 heads

HHT = 1/8 = 2 heads

HTH = 1/8 = 2 heads

HTT = 1/8 = 1 head

THH = 1/8 = 2 heads

THT = 1/8 = 1 head

TTH = 1/8 = 1 head

TTT = 1/8 = 0 head

So the probability of 3 heads is 1/8 and the amount is (1/8)* 0.14 = $0.0175

Probability of 2 heads is 3/8 and the amount is (3/8) * 0.06 = $0.0225

Probability of 1 head is 3/8 and amount is (3/8) * 0.01 = $0.00375

Total expected amount = 0.00375 + 0.0225 + 0.0175

Total expected amount = $0.04375

Ms. Geronimo has a $10 gift certificate to her local bakery.

Answer: a) 13 macaroons

b) 6 cookies

Step-by-step explanation: Total = $10

a) $2.20/slice of pie

$0.60/macaroon

10 - 2.20 = 7.80

7.80/0.6 = 13

b) $4.60/loaf

cookies = 1 1/2*macaroons = (1 + 0.5)*0.6 = 1,5 * 0.6 = 0.90

cookies = $0.90

10 - 4.60 = 5.40

5.40/0.9 = 6

From the list below select the order pairs which satisfy the following equation -3x+y=2

dimulka [17.4K]

The equation and the ordered pair is an illustration of a linear function.

The order pair which satisfy the equation -3x+y=2 is (0,2)

<h3>How to determine the ordered pair</h3>

The equation is given as:

-3x + y = 2

Set x = 0

-3 * 0 + y = 2

Evaluate the product

y = 2

Hence, the order pair which satisfy the equation -3x+y=2 is (0,2)
