Answer:

(C)5

Step-by-step explanation:

From the given graph, we can determine the coordinates of the X an Y.

These are:

X(-4,2) and Y(-1,-3)

Since,  XY is the hypotenuse, then At point Z, the angle will be 90° and thus, XZ is the altitude.

Join, YZ such that the coordinates of Z  is (-1,2).

Then, the length of the segment YZ will be:

YZ=\sqrt{(-1+1)^2+(2+3)^2}

YZ=\sqrt{0+25}

YZ=5

Therefore, the length of the YZ is 5.

A hand of 5-card draw poker is a simple random sample from the standard deck of 52 cards. How many 5 draw poker hands are there?
kupik [55]

Answer:

There are 2,598,960 5 draw poker hands are there.

There are 311,875,200 5-stud poker hands.

Step-by-step explanation:

When the order is not important, we use the combinations formula:

For example, eating an apple and an orange is the same as eating an orange and an apple.

C_{n,x} is the number of different combinations of x objects from a set of n elements, given by the following formula.

C_{n,x} = \frac{n!}{x!(n-x)!}

When the order is important, we use the permutations formula:

For example, a 3 digit credit card password, 123 is different than 213.

The number of possible permutations of x elements from a set of n elements is given by the following formula:

P_{(n,x)} = \frac{n!}{(n-x)!)}

A hand of 5-card draw poker is a simple random sample from the standard deck of 52 cards. How many 5 draw poker hands are there?

Here, the ordering is not important, so we use the combinations formula.

C_{52,5} = \frac{52!}{5!47!} = 2598960

There are 2,598,960 5 draw poker hands are there.

In 5-card stud poker, the cards are dealt sequentially and the order of appearance is important. How many 5-stud poker hands are there?

The ordering is important, so we use the combinations formula.

P_{(52,5} = \frac{52!}{47!)} = 311875200

There are 311,875,200 5-stud poker hands.

Of the 240 sandwiches Joanna makes 20% are tuna sandwiches and 40% are jam sandwiches, and the rest are egg salad sandwiches.How
nikitadnepr [17]
240 = 100%
so 10% = 24 sandwiches 
all - (tuna) - (jam) = egg
100% - 20% - 40% = 40%
40% = 10%*4
40% = 24*4 = 96

the answer is 96 egg salad sandwiches
