You spin the spinner and flip a coin. Find the probability of the compound event.

Mademuasel [1]

Answer:

The probability of spinning an even number and flipping heads is 1/4

Step-by-step explanation:

You spin the spinner and flip a coin.

A spinner that has 1 of each number, 1-6

Total events =12

(1,H),(2,H),(3,H),(4,H),(5,H),(6,H)

(1,T),(2,T),(3,T),(4,T),(5,T),(6,T)

We are supposed to find probability of spinning an even number and flipping heads

Favorable events : (2,H),(4,H)(6,H) = 3

Total events = 12

The probability of spinning an even number and flipping heads = $\frac{3}{12}=\frac{1}{4}$

Hence The probability of spinning an even number and flipping heads is 1/4

Samantha invested in the Graham Corporation. Samantha bought n number of shares for d dollars and paid a 2% commission to her br

DiKsa [7]

Answer:

Net Proceeds = Selling Price - Total Cost Price

a. Samantha

Total Cost Price;

Bought shares for d dollars and paid 2% commission = d + (d * 2%) = 1.02d

Selling Price;

Sold stock for s dollars and paid flat fee of $11 = s - 11

Net Proceeds = (s - 11) - 1.02d

b. Alex

Total Cost Price;

Bought x dollars worth and paid 1% commission = x + (x * 1%) = 1.01 * x = 1.01x

Selling Price;

Value falls to y and Alex pays 1.25% when he sells = y - (y * 1.25%) = y - 0.0125y = 0.9875y

Net Proceeds = 0.9875y - 1.01x

The mean distance of the Moon from Earth is 2.39x10^5 miles. Assuming that the orbit of the Moon around Earth is circular and th

olya-2409 [2.1K]

Answer:

2291,94 mph

Step-by-step explanation:

To solve this we need to consider the distance 2.39x10^5 miles as the distance between the center of the earth and the center of the moon, if not we would need to know the radius of the earth and the moon.

If the distance is 2.39x10^5 miles, the orbit is = 2.Pi.(2.39x10^5) miles=1501681.288miles

It takes 27.3 days, that are, 27.3*24= 655.2hours

1501681.288miles/655.2hours= 2291.94 mph
