A poker player holds a flush when all 5 cards in the hand belong to the same suit. We will find the probability of a flush when 5 cards are dealt. Remember that a deck contains 52 cards, 13 of each suit, and that when the deck is well shuffled, each card dealt is equally likely to be any of those that remain in the deck. We will concentrate on spades. What is the probability that the first card dealt is a spade? What is the conditional probability that the second card is a spade given that the first is a spade?

Answers

Answer 1

Step-by-step explanation:

that would be 1/52

since deck means 52

Determine the measurements of 1 angle in the figure

Answers

Angle 1 is equal to 68

All angles of a triangle add up to 180 degrees.

Angle 1 + 72 + 40 = 180
Angle 1 + 112 = 180
Angle 1 = 180 - 112
Angle 1 = 68

Thus, you answer should be 68

why does the formula for area of a circle make sense

Answers

Answer:

Step-by-step explanation:

The usual definition of pi is the ratio of the circumference of a circle to its diameter, so that the circumference of a circle is pi times the diameter, or 2 pi times the radius. The animation above shows that a circle can be cut and rearranged to closely resemble a parallelogram (with height r and base pi times r) of area pi times the square of the radius. By dividing the circle into more than eight slices, the approximation obtained in this manner would be even better. By dividing the circle into more and more slices, the approximating parallelograms approximate the area of the circle arbitrarily close. This give a geometric justification that the area of a circle really is "pi r squared".

mark owes his sister $15.he earned $20 for mowing the grass. he gave 1/5 of his warning to a local charity and then paid his sister. does mark have enough to repay his sister the full amount?

Answers

Answer:

Yes, with some change to spare.

Step-by-step explanation:

He has 20$. Take 1/5 of it, it's 4$ (because 4x5 = 20), so he will be left with 16$. He owes less than this, 15$, so he can repay his debt in full and have still 1$ left.

A) 1, 4, 5, 9, 14, 23, 37

B) 2, 4, 6, 10, 16, 26, 42

Step-by-step explanation:

1. The Fibonacci sequence states that each number is the sum of the two numbers before it.

For example, if we have the first two numbers of a sequence as 5 then 6, the next term would be 11.

2. Given the information above, let's solve the question.

-> A: 9 + 14 = 23, 14 + 23 = 37

The next two terms for sequence A are 23 then 37

-> B: 10 + 16 = 26, 16 + 26 = 42

The next two terms for sequence B are 26 then 42

Therefore, the answer is:

A) 1, 4, 5, 9, 14, 23, 37

B) 2, 4, 6, 10, 16, 26, 42

Multiply both sides by 2.

Two trains leave the station at the same time, one heading west and the other east. The westbound train travels  18  miles per hour slower than the eastbound train. If the two trains are  300  miles apart after  2  hours, what is the rate of the westbound train? Do not do any rounding.​

Answers

Answer:

66 mph

Step-by-step explanation:

w = e - 18

2w + 2e = 300

2 (e - 18) + 2e = 300

2e - 36 + 2e = 300

4e - 36 = 300

4e = 300 + 36 = 336

e = 84 mph

w = 66 mph

The westbound train is travelling at 66 mph

Looks like a  typo in the question

To get the unit rate, divide the miles by the hours

Unit rates

1000 miles in 2 hours = 1000/2 = 500

I'm guessing you meant 100 miles not 1000 miles

100 miles in 2 hours = 100/2 = 50

A gallon is 128oz. An airplane can carry 1,445 gallons of fuel. Write the number of ounces of fuel the plane can carry.

Answers

Step-by-step explanation:

one gallon is 128oz.

1445 gallons are how many Oz?

that applies the same principle as every-day situations like "every guest will eat 2 dumplings. 12 guests are coming, so how many dumplings do I have to prepare ?"

or totally simple : "every child will get one gift. 4 children are coming, so how many gift do I have to prepare ?"

it all works with multiplication. it is the ultimate application for multiplication.

that is why we use "times" in normal language as in mathematical terms. like "it takes 3 screws to mount a leg to a table. and the table needs 4 legs. how many times do I need to fasten a screw to finish one table ?" well, 4 times 3 or 4×3 = 12 times.

and so, the answer to the original question is then I need to take the amount of one gallon 1445 times.

128 × 1445 = 184,960oz
