How many different outcomes are possible when a nickel,a quarter and a penny are flipped at the came time? Solve by applying the counting principle

Answers

Answer 1

The coin values don't matter. What does is the fact that each can land on either heads or tails. There are 3 coins, so you would do 3!, or 3 factorial. 3! = 3 * 2 * 1, or 6. Thus, there are 6 possible outcomes.

I have two dice, one red and one blue. when the two dice are rolled, the probability that the number showing on the red die is larger than the number showing on the blue die si

Answers

Total possible outcomes are= 6×6=36

For example, if you roll a 1 on the blue dice, you cannot roll another 1 (since 1 is not bigger than 1).

Rolling a 2, you'd have 4 possible choices left (you cannot roll a 1 or 2 since they are less than 2).

(1/6)<-- picking a 1/2/3/4/5/6 out of everything;

(1/6)(5/6)=5/36 <-- (5/6) possibilities of picking a number bigger than 1
(1/6)(4/6)=4/36 <-- (4/6) possibilities of picking a number bigger than 2
(1/6)(3/6)=3/36
(1/6)(2/6)=2/36
(1/6)(1/6)=1/36
(1/6)(0)=0 <-- Impossible to get a number bigger than 6 in a normal dice

Add all of them together;

(5+4+3+2+1+0)/36=15/36

Therefore, there are 15/36 possibilities of the red die showing a number larger than that of the blue die.

Convert 4/6 into a fraction with a denominator of 24

Answers

The correct answer would be 16/24. You would need to multiply both the denominator and numerator by 4.

Since 6 is the denominator of 4/6 and the denominator needs to be 24 for the converted fraction, divide 24 by 6 to figure out what to multiply the numerator with which is 4. The converted fraction is 16/24

How does the graph of g(x) = 1/x+4-6 compare to the graph of the parent function f(x)=1/x ?

Answers

you can recall that
f(x-c) is shifting to the right by c units
f(x+c) is shifting to the left by c units
f(x)+c is shifting up by c units
f(x)-c is shifting down by c units
given that f(x)=1/x
g(x)=f(x+4)-6 thus f(x) is shifted to the left 4 units and down 6 units

Answer with explanation:

We are given a parent function f(x) as:

[tex]f(x)=\dfrac{1}{x}[/tex]

and the transformed function g(x) is given by:

[tex]g(x)=\dfrac{1}{x+4}-6[/tex]

We know that the transformation of the type:

f(x) → f(x+a)

is either a shift a units to the left or to the right depending whether a is positive or negative respectively.

Also, the transformation of the type:

f(x) → f(x)+a

is the shift of the function f(x) either upward or downward depending on whether x is positive or negative respectively.

Here the function g(x) is:

[tex]g(x)=f(x+4)-6[/tex]

This means that the function g(x) is a shift of the function f(x) 4 units to the left and then it is translated 6 units downward.

Also we may see by the graph.

x + 12 = 4y

Solve the second equation for x:

x = 4y - 12

Substitute in the first equation.

2(4y - 12) + 6 = 3y

8y - 24 + 6 = 3y

8y - 18 = 3y

5y = 18

y = 18/5

x + 12 = 4y

x + 12 = 4(18/5)

x = 72/5 - 60/5

x = 12/5

Answer: x = 12/5; y = 18/5

ahemmm if you meant to put it in decimal form.

well, in scientific notation, you always end up with one number to the left-hand-side of the dot, and the rest to the right of it.

now, we have the 10 with some base, if the base is positive, you move the dot to the right as many slots as the exponent says, for example,

[tex]\bf 2.077\times 10^{10}\impliedby \textit{10 slots to the right} \\\\\\ 2\stackrel{\textit{10 slots over}}{0770000000}\stackrel{\downarrow }{.}\implies 20770000000[/tex]

now, in this case, is a negative number, -4, so, we move the dot, 4 slots but to the left, thus

[tex]\bf 2.077\times 10^{-4}\impliedby \textit{4 slots to the left} \\\\\\ \stackrel{\downarrow }{.}\stackrel{\textit{moved 4 slots to the left}}{0002}077\implies 0.0002077[/tex]

Harry works for a major sporting goods distributor. He earns a base salary of $30,000 per year and 5% commission on his sales. How much will Harry need to sell to earn $50,000 by the end of the year?

Answers

He needs to sell $400,000 worth of goods.

Base salary = $30000

Percent Commission = 5%

Let the amount of goods that need to be sold be represented by x

Therefore, the equation will be:

30000 + (5% × x) = 50000

30000 + (0.05 × x) = 50000

30000 + 0.05x = 50000

Collect like terms

0.05x = 50000 - 30000

0.05x = 20000

x = 20000/0.05

x = 400000

Therefore, he needs to sell $400,000 worth of goods.

On a quiz, students were awarded a certain number of points for a correct answer and penalized a certain number of points for an incorrect answer. If a student answered all the questions on the quiz and had c correct answers, her score on the quiz was 25c – 10(15 – c). How many questions were on the quiz?

Answers

Given that the score of the student on the quiz was 25c - 10(15 - c)

It can be seen that the first term of expression for her score (i.e. 25c) shows that 25 marks were awarded to each correct answer.

The second term of the expression (i.e. 10(15 - c)) represent that 10 marks were deducted from each wrong answer.

Thus, the number of wrong answers is 15 - c.

The sum of the correct answers and the wrong answers gives the total number of questions in the quiz.

Thus, the total number of questions in the quiz is given by 15 - c + c = 15.

Therefore, there are 15 questions in the quiz.

What is compound interest?

The interest charged on a loan or deposit is known as compound interest. In our day-to-day lives, it is the concept we use the most. The amount's compound interest is based on both the principal and the interest earned over time. This is the primary distinction between simple and compound interest.

Given annually increase rate of computers = R = 23.2%

people own computer in 1990 = 1/2 million = 0.5 million

let no. of people own computer in 2015 be x

compound interest for annually increase in rate is p[tex](1 + R/100)^{t}[/tex]

where t = time and R = rate

Time = 2015 - 1990 = 25 years

x = 0.5(1 + 23.2/100)²⁵

x = 0.5(1.232)²⁵

x = 0.5 × 184.1906

x = 92.0953 million

Hence 92.0953 million people own computer in 2015.

A bag contains 6 blue marbles, 10 red marbles, and 9 green marbles. If two marbles are drawn at random without replacement, what is the probability that two red marbles are drawn?

Answers

So since there are 6 blue marbles, 10 red marbles, and 9 green marbles, that means that there are 25 marbles in total. This means the chance of pulling ONE red marble is 10/25 which simplifies to 2/5. If you want to pull 2 red marbles, you'd multiply the chance of pulling one marble to the chance of pulling one marble. (2/5 times 2/5)
You'd get 4/10. Which is a 40% percent chance.
(not completely sure about this one..)

6 blue, 10 red, 9 green...for a total of 25 marbles

P(1st one drawn is red) = 10/25 reduces to 2/5
without replacement
P(2nd one drawn is red) = 9/24 reduces to 3/8

P(both events happening) = 2/5 * 3/8 = 6/40 reduces to 3/20 <=
