20) Solve the problem. Suppose that 12 unique names are put into a hat and drawn at random without
replacement. How many different ways can you draw all of the names from the hat? Remember that
"without replacement" means that the names are not returned to the hat after they are chosen. Write your
answer in factorial notation.
SHOW WORK: None to be shown
A) 12!
B) 11!
C) 10!
D) 12! - 1

Answers

the answer would be A) 12 because there are only twelve names

The number of different ways is 12! you can draw all of the names from the hat without replacement option (A) 12! is correct.

What are permutation and combination?

A permutation is the number of different ways a set can be organized; order matters in permutations, but not in combinations.

It is given that:

Number of unique names = 12

That 12 unique names are put into a hat and drawn at random without

replacement.

"Without replacement" means that the names are not returned to the hat after they are chosen.

Number ways (without replacement) = 12x11x10x9x8x7x6x5x4x3x2x1

Number ways (without replacement) = 12!

Thus, the number of different ways is 12! you can draw all of the names from the hat without replacement option (A) 12! is correct.

A chemist has 100 ml of 25% acid solution. how much of the solution does she need to drain and replace with 70% acid solution to obtain 100 ml of 60% acid solution?

Answers

Answer:

The proportion of acid at 70% that the chemist must use will be 77.8%, while the remaining 22.2% will be acid at 25%.

Step-by-step explanation:

Since the chemist has 100 ml of solution with 25% acid, and wants to obtain a solution of 60% acid by mixing the first with another 70% acid solution, to determine how much of each solution the chemical should use necessary to perform the following calculation:

70 x 1 + 25 x 0 = 70

70 x 0.9 + 25 x 0.1 = 65.5

70 x 0.8 + 25 x 0.2 = 61

70 x 0.7 + 25 x 0.3 = 56.5

Therefore, the proportion to be used is between 70% and 80% of acid at 70%, and 20% to 30% of acid at 25%.

70 x 0.75 + 25 x 0.25 = 58.75

70 x 0.76 + 25 x 0.24 = 59.2

70 x 0.77 + 25 x 0.23 = 59.65

70 x 0.78 + 25 x 0.22 = 60.1

Thus, the proportion should be between 77 and 78% of acid at 70% and 22 and 23% of acid at 25%.

70 x 0.778 + 25 x 0.222 = 60.01

Thus, finally, the proportion of acid at 70% that the chemist must use will be 77.8%, while the remaining 22.2% will be acid at 25%.

Answer:

-63

Step-by-step explanation:

PEMDAS stands for:

P -> Parentheses

E -> Exponents

M -> Multiplication (left to right)

D -> Division (left to right)

A -> Addition (left to right)

S -> Subtraction (left to right)

So in this problem, we can't evaluate the parentheses unless we evaluate the exponent first:

(-25+4^2)*7

(-25+16)*7

Next, we evaluate the parentheses by adding from left to right since there's no multiplication or division in the parentheses:

(-25+16)*7

(-9)*7

Lastly, we do multiplication:

(-9)*7

-63

Thus, our final answer is -63

What is rate of change?Rate is defined as the rate of change of one variable with respect to other variable.

{r} = dy/dx

In mathematics, an expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.Mathematical symbols can designate numbers (constants), variables, operations, functions, brackets, punctuation, and grouping to help determine order of operations and other aspects of logical syntax.

Given is that Ricardo ran the 60-meter sprint in 5 s.

Ricardo’s rate in meters per second

r = d/t

r = 60/5

r = 12

Therefore, Ricardo’s rate in meters per second is equivalent to 12 meters per second.
