Answer:

(a) What is the probability that you roll a 6?

1/6

(b) What is the probability that you either roll a 6 or do not roll a 6?

1

(c) What is the probability that you don't roll a 6?

5/6

Step-by-step explanation:

(a) What is the probability that you roll a 6?

In a 6- sided cube, a 6 occurs only once. That is only one face is labelled 6. Therefore, the probability that you roll a 6 is;

(number of faces labelled 6)/(totals number of sides) = 1/6

(b) What is the probability that you either roll a 6 or do not roll a 6?

The probability of rolling a 6 was found to be, 1/6.

On the other hand, the probability of not rolling a 6 is;

(number of faces not labelled 6)/(totals number of sides) = 5/6

Therefore, the probability that you either roll a 6 or do not roll a 6 is;

1/6 + 5/6 = 1

These two events are mutually exclusive and exhaustive.

(c) What is the probability that you don't roll a 6?

The probability of not rolling a 6 is;

(number of faces not labelled 6)/(totals number of sides) = 5/6

We have 5 faces not labelled 6 out of 6 possible faces or outcomes

Answer:

y = 3x - 3

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (0, - 3) and (x₂, y₂ ) = (1, 0) ← 2 points on the line

m = [tex]\frac{0+3}{1-0}[/tex] = 3

The line crosses the y- axis at (0, - 3) ⇒ c = - 3

y = 3x - 3 ← equation of line

The equation of line l will be;

⇒ y = 3x - 3

The equation of line in point-slope form passing through the points

(x₁ , y₁) and (x₂, y₂) with slope m is defined as;

⇒ y - y₁ = m (x - x₁)

Where, m = (y₂ - y₁) / (x₂ - x₁)

Given that;

Two points on the line are (1, 0) and (0, -3).

Now,

Since, The equation of line passes through the points (1, 0) and (0, -3).

So, We need to find the slope of the line.

Hence, Slope of the line is,

m = (y₂ - y₁) / (x₂ - x₁)

m = (- 3 - 0) / (0 - 1)

m = - 3 / - 1

m = 3

Thus, The equation of line with slope 3 is,

⇒ y - 0 = 3 (x - 1)

⇒ y  = 3x - 3

Therefore, The equation of line passes through the points (1, 0) and

(0, -3)  will be;

⇒ y = 3x - 3

Answer:

(3a-1)(3a+1)

Step-by-step explanation:

This is the difference of two squares so we can factorise using the rules

x^2-y^2 = (x-y)(x+y)

In this case x = 3a and y = 1 since (3a)^2 = 9a^2 and 1^2 = 1

First, find the area of lot A.

To find the area, multiply the length by the width.

33*42=1,386

Now, subtract the area of lot a from the total area. This will give us the area of lot b.

1,848-1,386=462

The area of lot b is 462 square feet.

Finally, divide the area of lot b (462) by its length to find the width. Since they both share a side, we know that it’s length is 42 feet.

462/42=11

Lot b is 11 feet wide.

Answer:

$16.50/hr

Step-by-step explanation:

Current pay is 1.00($15/hr).

Current pay plus a 10% raise is 1.10($15/hr) = $16.50/hr

After receiving a 10% raise on a $15 per hour wage, you would be earning $16.50 per hour.

If you are currently making $15 per hour and you receive a 10% raise, you can calculate your new hourly wage by first determining the amount of the raise and then adding it to your current wage. To find the raise amount, you multiply your current wage by the raise percentage expressed as a decimal. In this case:

Amount of raise = Current hourly wage  imes Raise percentage

Amount of raise = $15 per hour  imes 0.10 (since 10% = 0.10)

Amount of raise = $1.50 per hour

Now, you add this raise to your current hourly wage to find your new hourly wage:

New hourly wage = Current hourly wage + Amount of raise

New hourly wage = $15 per hour + $1.50 per hour

New hourly wage = $16.50 per hour

To give an example for comparison, if your job pays $10 per hour and your boss gives you a $2 per hour raise, that is a 20% increase because the percentage change is calculated as $2/$10 = 0.20 or 20%. In your case, the 10% raise increases your wage by $1.50, making it $16.50 per hour after the raise.

Check the picture below.

so let's notice, the base is a 6x6 square, and triangular faces have a base of 6 and an altitude/height of 5.  So we can just get the area of the square and the triangles and sum them up and that's the area of the pyramid.

Answer:

1.27, -6.27 to the nearest hundredth,

or if you require it in exact form,

-2.5 + √14.25,   -2.5 - √14.25.

Step-by-step explanation:

x^2 = -5x + 8

x^2 + 5x  = 8

Competing the square:

(x + 2.5)^2 - 6.25 = 8

(x + 2.5) = 14.25

x + 2.5 = +/-√14.25

x = -2.5 + √14.25,   -2.5 - √14.25

x = -2.5 + 3.77,  -2.5 - 3.77

Answer:

y = 100x + 400

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (0, 400) and (x₂, y₂ ) = (1, 500) ← 2 points from the table

m = [tex]\frac{500-400}{1-0}[/tex] = 100

note the line crosses the y- axis at (0, 400) ⇒ c = 400

y = 100x + 400 ← equation of line

The equation of the line represented by the following table in slope-intercept form is y = 100x + 400.

The equation of a straight line in the form y = mx + c where m is the slope of the line and c is its y-intercept is known as the slope-intercept form. Here both the slope (m) and y-intercept (c) have real values. It is known as slope-intercept form as it gives the definition of both the slope and y-intercept.

Slope of a straight line can be found using two given points say (x1,y1) and (x2,y2).

Slope (m) = (y2 - y1) / (x2 - x1) .

Taking any two arbitrary points, from the table given aside we have x1 = 0, x2 = 1, y1 = 400 and y2 = 500

⇒ Slope (m) = (y2 - y1) / (x2 - x1) .

=  (500 - 400)/(1 - 0)

∴  Slope (m) = 100 .

The y-intercept of the line is the value of y coordinate when the value of x = 0. In other words, y-intercept is the point where the curve touches the y-axis.

∴ From the table, y-intercept (c) = 400 .

Thus, we have slope (m) = 100 and y-intercept (c) = 400 .

The equation of straight line is y = 100x + 400 .

Therefore, the equation of the line represented by the following table in slope-intercept form is y = 100x + 400.

[tex]TotalSurfaceArea=192ft^{2}[/tex]

To calculate the surface area of a square pyramid, we need to use the following formula:

[tex]TotalSurfaceArea=\frac{1}{2}pl+BaseArea[/tex]

Where,

p, is the perimeter of the base.

l, is the slant of the pyramid.

Base area, is the area of the square base.

Answer:

3x+24 more widgets

Step-by-step explanation:

A company owns two manufacturing plants:

To find how many more items the first plant produces daily than the second plant, we have to subtract from the number of widgets the first plant produces the second plant produces. So,

[tex](8x+17)-(5x-7)\\ \\=8x+17-5x+7\ [\text{Eliminate brackets}]\\ \\=(8x-5x)+(17+7)\ [\text{Combine the like terms}]\\ \\=3x+24[/tex]

Answer:

3x + 24

Step-by-step explanation:

The question simply requires us to find the difference between the daily production levels of the two plants;

The first plant produces 8x + 17

The second plant produces 5x - 7

The difference between these two expressions will be our required solution;

(8x + 17) - ( 5x - 7) = 8x + 17 - 5x + 7

= 8x - 5x +17 + 7 = 3x + 24

Step-by-step explanation:

Use Pythagoras Theorem a² = b² + c²

In this case a = 12 and c = 8 so,

12² = b² + 8²

( Simplify )

144 = b² + 64

( Minus 64 from both sides to isolate b² )

80 = b²

( Square root to isolate b )

8.94427191 = b

Answer:

8.9

Step-by-step explanation:

The triangle is a right triangle, so we can use the Pythagorean theorem, where a and b are the lengths of the legs (the sides forming the right angle), and c is the length of the hypotenuse (the angle opposite the right angle).

a^2 + b^2 = c^2

y^2 + 8^2 = 12^2

y^2 + 64 = 144

y^2 = 80

Step-by-step explanation:

A good trick to remember is SOH CAH TOA.

Sine = Opposite / Hypotenuse

Cosine = Adjacent / Hypotenuse

Tangent = Opposite / Adjacent

Here, we're given an angle and the opposite side, and we want to find the adjacent side.  So we need to use tangent.

tan 31° = 24 / x

x = 24 / tan 31°

x ≈ 39.9

For this case we must solve each of the equations proposed:

A) [tex]m ^ 2 + 9 = 58[/tex]

Subtracting 9 from both sides of the equation we have:

[tex]m ^ 2 = 49[/tex]

Applying root to both sides of the equation:

[tex]m = \sqrt {49}\\m = \pm7[/tex]

B) [tex]7e ^ 2 = 28[/tex]

We divide between 7 on both sides of the equation:

[tex]e ^ 2 = \frac {28} {7}\\e ^ 2 = 4[/tex]

We apply root to both sides of the equation:

[tex]e = \pm \sqrt {4}\\e = \pm2[/tex]

C) [tex]d ^ 2 + 6 = 70[/tex]

Subtracting 6 on both sides of the equation:

[tex]d ^ 2 = 64[/tex]

We apply root to both sides of the equation:

[tex]d =\pm \sqrt {64}\\d = \pm8[/tex]

D) [tex]\frac {1} {2} n ^ 2-10 = 62[/tex]

We add 10 to both sides of the equation:

[tex]\frac {1} {2} n ^ 2 = 72[/tex]

We multiply by 2 both sides of the equation:

[tex]n ^ 2 = 144[/tex]

We apply root to both sides of the equation:

[tex]n = \pm \sqrt {144}\\n =\pm12[/tex]

Answer:

[tex]m = \pm7\\e = \pm2\\d = \pm8\\n = \pm12[/tex]
