Brett rolls a number cube labeled from 1 to 6 and tosses a penny at the same time. What is the probability that he will roll an even number and toss heads?

Answers

Answer:

1/4

Step-by-step explanation:

We are informed that a cube labeled from 1 to 6 is rolled. The numbers on the faces of the cube are;

1, 2, 3, 4, 5, 6

The probability of rolling an even number is;

(total number of faces with even numbers) / (total number of faces)

The even numbers are;

2, 4, 6

The probability of rolling an even number is thus;

3/6 = 1/2

If a penny is tossed, the probability of landing heads is simply;

1/2

This is because there are only two possible outcomes; heads or tails with equal probability assuming the penny is fair.

now, the probability that he will roll an even number and toss heads is;

1/2 * 1/2 = 1/4

we simply find the product of the probabilities of the individual events since they are independent.

Answer:

Part 1) 53%

Part 2) 44%

Part 3) The record label sold a higher percentage of album 1 as digital downloads than album 2

Step-by-step explanation:

First we need to find the total sales of each album

Album 1:

[tex]540+470=1010[/tex]

Album 2:

[tex]571+452=1023[/tex]

Part 1)

In order to find the percentage of copies of album 1 sold as CDs, we need to create a fraction with the number of CD sales over the total number of sales

[tex]\frac{540}{1010} =0.534\\\\0.534*100=53.4\\\\53[/tex]

Part 2)

We must now do the same thing with the number of digital downloads for album 2

[tex]\frac{452}{1023} =0.441\\\\0.441*100=44.1\\\\44[/tex]

Part 3)

We can now do this again with the number of digital downloads for album 1 and compare it to the answer in Part 2

[tex]\frac{470}{1010} =0.465\\\\0.456*100=46.5\\\\47[/tex]

As the % for album 1 is 47% while the % for album 2 is 44%, album 1 sold a higher percentage of digital downloads than album 2

Which value of x is in the solution set of 2x-3>11-5x

Answers

7x>14,x=2። is right answer i think

7x>14,x=2። is right answer i think

Answer:

Value of x > 2 is in the solution set of 2x-3>11-5x which means the value of x can be any value greater than 2.

Step-by-step explanation:

We need to find the value of x for the equation 2x-3>11-5x

2x-3>11-5x

Adding +5x on both sides:

2x+5x-3>11-5x+5x

7x-3>11

Adding +3 on both sides

7x-3+3>11+3

7x>14

Dividing by 7 on both sides:

7x/7>14/7

x>2

Value of x > 2 is in the solution set of 2x-3>11-5x which means the value of x can be any value greater than 2.

Express the square root of -80 in its simplest terms.

A- cannot be determined
B- 8i sqrt 10
C- 4i sqrt 5
D- 2i sqrt 20

Answers

Answer:

C

Step-by-step explanation:

noting that [tex]\sqrt{-1}[/tex] = i

Given

[tex]\sqrt{-80}[/tex]

= [tex]\sqrt{16(-1)(5)}[/tex]

= [tex]\sqrt{16}[/tex] × [tex]\sqrt{-1}[/tex] × [tex]\sqrt{5}[/tex]

= 4i[tex]\sqrt{5}[/tex] → C

The square root of -80, expressed in simplest terms, is 4i sqrt 5, where 'i' is the imaginary unit.So,option C is correct.

To express the square root of -80 in its simplest terms, we need to use the imaginary unit i, which is defined as the square root of -1. We can rewrite -80 as -1  imes 80, and thus the square root of -80 as the square root of -1 times the square root of 80. We know that the square root of -1 is i, and the square root of 80 can be simplified to the square root of 16 times the square root of 5, which is 4 times the square root of 5. Combining these, we get:
√-80 = √(-1 times 80)
      = √-1 times √80
      = i times 4√5
      = 4i√5.

The correct answer is C- 4i sqrt 5.

Solve for x in the equation ? 2x^2 +3 x-7 =x^2 +5x +39

Answers

Answer:

Step-by-step explanation:

Combine like terms in 2x^2 +3 x-7 =x^2 +5x +39:

2x^2 - x^2 = x^2 (first term);

3x - 5x = -2x (second term);

Solve for the variable: 3.5x=32.2
What’s the variable?

Answers

Answer:

The variable is x.

The value of the variable is 9.2.

Step-by-step explanation:

The equation shows the variable x multiplied by 3.5 with the result of that multiplication being 32.2. In order to solve for x, you must "undo" that multiplication.

The definitions of the multiplicative inverse and of the multiplication identity element tell you how to do that. The multiplicative inverse of a number is its reciprocal: the multiplicative inverse of 3.5 is 1/3.5. Multiplying a number by its multiplicative inverse gives a result of 1. Here, that means ...

3.5 × (1/3.5) = 1

The property of the multiplicative identity element (1) is that anything multiplied by that is just that thing:

x · 1 = x

So, to solve this equation, you multiply both sides by the multiplicative inverse of 3.5:

3.5x = 32.2

(1/3.5)(3.5)x = (1/3.5)(32)

1x = 9.2 . . . . . carry out the multiplication

x = 9.2 . . . . . . recognize 1x = x

___

You will recognize that multiplying by 1/3.5 is the same as dividing by 3.5. In other words, we solve this equation by dividing it by the coefficient of x.

Answer:

The variable is x and x is equal to 9.2

Step-by-step explanation:

Keep in mind that a variable is a symbol put in place to represent an unknown value. In this case, our variable is "x."

In order to solve for x, we must isolate it. We can do this by dividing both sides of the equal sign by 3.5

3.5x ÷ 3.5 = 32.2 ÷ 3.5

Simplify.

x = 9.2

Factorise:-
x^3 - 6x^2 + 11x - 6

Answers

Answer:

(x - 1)(x - 2)(x - 3)

Step-by-step explanation:

Note the sum of the coefficients

1 - 6 + 11 - 6 = 0

hence x = 1 is a root and (x - 1) is a factor

dividing x³ - 6x² + 11x - 6 by (x - 1) gives

(x - 1)(x² - 5x + 6)

To factor the quadratic

Consider the factors of + 6 which sum to give - 5

The factors are - 2 and - 3, since

- 2 × - 3 = 6 and - 2 - 3 = - 5, hence

x² - 5x + 6 = (x - 2)(x - 3) and

x³ - 6x² + 11x - 6 = (x - 1)(x - 2)(x - 3)

Answer:

(x - 1)(x - 2)(x - 3).

Step-by-step explanation:

f(x) = x^3 - 6x^2 + 11x - 6

f(1) = 1 - 6 + 11 - 6 = 12 - 12

= 0 so by the Factor Theorem (x - 1) is a factor.

Also, by the Rational Root theorem, as the last term is -6 and the leading coefficient is 1  some of -1, 2,-2, 3 -3, 6,-6  might be zeroes of the function.

f(-1) = -1 + 6 - 11 - 6 = -12 so  -1 is not a zero and (x+ 1) is not a factor.

f(2) = 8 - 24 +22 - 6

= 30 - 30 = 0  so (x - 2) is also a factor)

Since the last term is -6 the last  factor must be  (x - 3)

=Checking:  f(3) = 27 -6(9) + 33 - 6

= 27 - 54 + 33 - 6

= 60-60 = 0.

So the factors are (x - 1)(x - 2)(x - 3).

Find the value of h for the parallelogram

Answers

Answer:

h = 5.488 in

Explanation:

Area of a parallelogram is calculated as follows:

Area = base * height

In the given parallelogram, we can note that the base is 9.8 in and the corresponding height is 5.6 in

This means that:

Area of parallelogram = 9.8 * 5.6 = 54.88 in²

This same area can be calculated using the other base (10 in) and its corresponding height (h)

This means that:

Area of parallelogram = 10 * h

54.88 = 10 * h

h = 5.488 in

Katrina earns $9.25 per hour plus a 12% commission on any sales she makes. In one day, she worked for 11 hours, and she made $385 in sales. About how much money did Katrina earn that day?

Answers

Katrina earned approximately $147.95 that day.

To calculate how much money Katrina earned in one day, we need to take into account her hourly wage as well as her commission from sales. The first part is straightforward: She works 11 hours at an hourly rate of $9.25. To find this portion of her earnings, we multiply the number of hours by her hourly rate:

11 hours * $9.25 per hour = $101.75

Next, we calculate the commission from her sales. Katrina made $385 in sales and gets a 12% commission on these sales:

12% of $385 = 0.12 * $385 = $46.20

To find Katrina's total earnings for the day, we add her hourly earnings to her commission earnings:

$101.75 (hourly earnings) + $46.20 (commission) = $147.95

Therefore, Katrina earned approximately $147.95 that day
