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.

Use the formula to estimate the temperature when n = 20 chirps/min. Round to the nearest whole number, if necessary.

Answers

I guess the formula you should have posted is Dolbear's Law
Temp (F) = 50 + ([Chirps per minute -40] /4)
Temp (F) = 50 + ([20 -40]/4)
Temp (F) = 50 + (-20 / 4)
The temperature in degrees Fahrenheit is 45 degrees

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 <=

Let y be inversely proportional to x. if x doubles, what happens to y?

Answers

Final answer:

If x doubles and y is inversely proportional to x, then y will become half of its original value, as per the inverse proportionality relation y = k/x.

Explanation:

When variables y and x are inversely proportional, this means that as one value increases, the other value decreases. The relationship between y and x in this case is represented by the equation y = k/x, where k is the proportionality constant. If the value of x doubles, looking at the relationship expressed by the inverse proportionality equation, the value of y will decrease by half.

So, if x becomes 2x, then y becomes k/(2x), which is half the value of the original y if we assume that k is constant. This is reflective of the more-less relationship inherent to inverse proportionality, where increased values of one variable lead to decreased values of the other.

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.

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.

ALGEBRA 2- Which property of addition is shown below?

If x = 1 + 2i and y = –1 – 2i, then x + y = 0.

A. commutative property
B identity property
C associative property
D inverse property

Answers

D. Inverse property

Inverse operations are used to solve simple algebraic equations to more difficult equations that involve exponents...

Answer:

D inverse property

Step-by-step explanation:

x=1+2i

y=-1-2i

Both x and y are complex numbers with both real and imaginary parts.

x+y = (1+2i) + (-1-2i)

= 1 + 2i - 1 - 2i

= (1 - 1) + (2i-2i)

= 0 + 0 = 0

Since the two given complex numbers add up to 0, this means that each number is the additive inverse of the other.

So x is the inverse of y and y is the inverse of x.

Among the given options, option D , namely, inverse property is the correct one.

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]

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.

Solve the second equation for x:

Substitute in the first equation.

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

8y - 24 + 6 = 3y

8y - 18 = 3y

5y = 18

x + 12 = 4y

x + 12 = 4(18/5)

Tamara earns her living as a salary plus commission employee. Her annual salary is $48,000, and she earns 4% commission on all sales she makes. If Tamara wants to make a total of $6,000 this month, how much in sales does she need to have?

Answers

$48000 / 12 months = $4,000 /month

$6000/month - $4000/month = $2000/month

$2000/month / (0.04) = $50,000/month in sales

Answer:

$5,000 in sales

Step-by-step explanation:

dividing the annual salary by 12 to find how much she makes in a month:

48,000/12 = $4,000

If she wants to make $6,000 this month, she needs

6,000 - 4,000 = $2,000 in comissions

$2,000 is the 4% of how much she made in sales.

denoting the total of sales by x:

4%x = 2,000

---> 0.04x = 2,000

this makes x = 2,000/0.04

--> x = $50,000

So to get a moth salary of $6,000 she needs to have $5,000 in sales
