What is the value of the expression?

Answer:

1/6

Step-by-step explanation:

no matter what, the die always has the same probability of landing on one specific number.

Really hope this helps!!

stay safe :0)

The required probability of both dice landing on 4 is 1/6.

The probability is defined as the possibility of an event is equal to the ratio of the number of favorable outcomes and the total number of outcomes.

If we already know that the first die has landed on 4, then the probability of the second die landing on 4 is the same as the probability of a single die landing on 4, which is 1/6.

This is because the two dice are independent of each other, and the outcome of the first die does not affect the outcome of the second die.

Therefore, the probability of two dice landing on 4 given that the first die has landed on 4 is 1/6 or approximately 0.1667.

Answer:

width = 2 units

Step-by-step explanation:

If the length of a rectangle is (x) units, then that means that the width of a rectangle is x - 4 units.

the area of a rectangle is length * width

so just substitute the values that we have now.

x (length) * (x-4) width = 12 (area of rectangle)

so that gives us

x^2 - 4x =12

subtract 12 from both sides

x^2 - 4x - 12 =0

now factor this equation

x^2 + 2x - 6x -12 = 0

x(x+2) - 6(x+2) = 0

(x-6)(x+2) = 0

x = 6, or x = -2 REMEMBER THAT VALUE OF x = LENGTH, IT CANNOT BE NEGATIVE AS YOU CANT HAVE NEGATIVE VALUE OF A SIDE

length = 6, and width = 6 -4 = 2

Answer:

W=2 units

Step-by-step explanation:

Length=L

Width=L-4

Area of a rectangle= L*W

L(L-4)=12

L^2-4L=12

L^2-4l-12=0

Now we have a quadratic equation

(L-6)(L+2)=0

L=6, L=-2

L cannot be -2 because it is negative, so L must be 6.

BUT it is asking for the width

and it is given that the width is the length minus 4 units, so

6-4= 2 units

Answer:

The area of the shaded region is [tex]18\ \text{units}^2[/tex].

Step-by-step explanation:

On the attached figure, a rectangle is shown. It is required to find the area of the shaded part. The shaded part forms a triangle. The area of a triangle is given by :

[tex]A=\dfrac{1}{2}\times b\times h[/tex]

b is base and h is height

From this figure, each box is a square of side 1 unit say.

Its height will be 4 units and its base is 9 units

So,

[tex]A=\dfrac{1}{2}\times 9\times 4\\\\A=18\ \text{units}^2[/tex]

So, the area of the shaded region is [tex]18\ \text{units}^2[/tex].

Answer:

[tex]31.5units^2[/tex]

Step-by-step explanation:

The shape shown above can be split into 2 triangles and 1 rectangle.

The formula for a triangle:

[tex]A=\frac{1}{2} bh[/tex]

The formula for a rectangle:

[tex]A=lw[/tex]

Area of triangle (both have the same lengths so you can just double the area):

[tex]A=\frac{1}{2} (3)(3.5)\\A=5.25[/tex]

Area of rectangle:

[tex]A=(7)(3)\\A=21[/tex]

Add the individual areas together to get the overall:

5.25 + 5.25 + 21 = 31.5

Answer:

P(Snickers n Snickers)  = [tex]\frac{2}{51}[/tex]

Step-by-step explanation:

Given

Bag of candy

5 Reese's Peanut Butter Cups,

4 Snickers

3 Sour Patch

6 Skittles

Required

Calculate P(Snickers n Snickers)

To solve this question, it'll be assumed that you and your friend selected snickers at a consecutive time.

First, we need to calculate the total number of candy

Total = 5 + 4 + 3 + 6

Total = 18 candies

P(Snickers n Snickers) means P(Snickers and Snickers);

i.e. the probability of selecting snicker twice

Number of snickers = 4;

So, the probability of you selecting a snicker first is [tex]\frac{4}{18}[/tex]

This is gotten by dividing number of snickers by total candies.

At this point, there are 4 - 1 snickers left and there are 18 - 1 candies left;

So, the probability of your friend selecting a snicker is [tex]\frac{4 - 1}{18 - 1}[/tex].

So, P(Snickers n Snickers)  = [tex]\frac{4}{18}[/tex] * [tex]\frac{4 - 1}{18 - 1}[/tex]

P(Snickers n Snickers)  = [tex]\frac{4}{18}[/tex] * [tex]\frac{3}{17}[/tex]

P(Snickers n Snickers)  = [tex]\frac{2}{9}[/tex] * [tex]\frac{3}{17}[/tex]

P(Snickers n Snickers)  = [tex]\frac{2}{3}[/tex] * [tex]\frac{1}{17}[/tex]

P(Snickers n Snickers)  = [tex]\frac{2}{51}[/tex]

Hence, the probability of you and your friend choosing snickers is [tex]\frac{2}{51}[/tex]

The equation that represents the relationship between x and y shown in the table is; y= 2x-3

An equation is an expression that shows the relationship between two or more numbers and variables.  the equations that can be solved to get a unique solution. the power of the equation must be in one degree.

First we need to find the slope we will use rise over run to get 2.

The correct equation will replace x with any of the x values in the chart and if we get the same y values as the chart then that equation is correct.

y= 2x-3

If x = 2 and y = 1

Then

y= 2x-3

1 = 2(2)-3

1= 1

Therefore, The equation that represents the relationship between x and y shown in the table is; y= 2x-3

Answer:

Negative 1.5 less than negative 0.5

Step-by-step explanation:

False, negative 1.5 would not be greater than 0.5 since negative 1.5 is a negative meaning it goes to the left of the zero, so it is less than 0.

False, negative 0.5 is again less than 0 so therefore it would not be greater.

False, one half is the same as 0.5 just in word form.

That means, negative 1.5 is less than negative 0.5 since it is further away from the 0.5 going to the left.

Left group: [tex]2x^{5\\}[/tex]     Right group: 3

Step-by-step explanation:

Right group: 3.x - 21 = 3.x - 3.7 = 3 . ( x - 7 )

21 is equal 3 times 7. When we do this change, it is clear which is the common factor, which is just the number 3.

Left group: 2[tex]x^{6\\}[/tex] + 14[tex]x^{5\\} \\[/tex]  =  2[tex]x^{5\\}[/tex].x + 2[tex]x^{5}[/tex].7 = 2[tex]x^{5\\}[/tex] . (x + 7)

Assuming t = two years

3% of $22.00 = .66

step-by-step

3 percent *22.00 =

(3:100)*22.00 =

(3*22.00):100 =

66:100 = 0.66

A) .66x2 = 1.32 + 22.00 = 23.32

after 2 years the plumber will make $23.32 per hour

B) .66x8 = 5.28 = 22.00 = 27.28

after 8 years the plumber will make $27.28 per hour

The required hourly rate for a plumber after 8 years will be $27.86 per hour.

The equation model is defined as the model of the given situation in the form of an equation using variables and constants.

here,
As mentioned in the question, a plumber works for $22 per hour. the hourly rate increases by 3% each year.
Let y be the hourly rate of the plumber after t years,
[tex]y = 22 [1 + 0.03]^t\\y = 22[1.03]t[/tex]

Put t = 8

[tex]y = 22 [1.03]^8\\y = 27.86[/tex]

Thus, the required hourly rate for a plumber after 8 years will be $27.86 per hour.

Answer:

because cosine dependency on sine - 1

Step-by-step explanation:

The unit circle has a radius of one, so the hypotenuse is 1. Sine is opposite over hypotenuse. Since the hypotenuse is 1, sine on the unit circle is the opposite side. When you look at the unit circle, the opposite side is perpendicular to the x-axis. This means that, essentially, the opposite side is the height from, or the distance from, the x-axis, which is the y-value.

a unit circle (a circle with radius one), is that if you draw a right triangle where the hypotenuse of the triangle connects a point on the unit circle with the point (0, 0), the length of the hypotenuse is always going to be one. Because that's the radius of the circle! And the length of the other two sides are just going to be the x and y coordinates of the point on the unit circle.

Take a little time drawing right triangles were the hypotenuse connects the middle of the unit circle to a point on the circle and see if you can convince yourself that this is the case.

So you have a right triangle where one side length is the x-coordinate and one side length is the y-coordinate, and the hypotenuse is equal to 1. This means you can figure out the sine and cosine of the angle that the hypotenuse and the x-axis make:

The cosine is the length of the adjacent side (which is the x-coordinate) divided by the length of the hypotenuse (which is 1). So the cosine is just the x-coordinate!

Similarly, the sine is the length of the opposite side (which is the length of the y-coordinate) divided by the length of the hypotenuse (which is 1). So the sine is the y-coordinate.

The trigonometric ratio defining the tangent (opposite over adjacent) may be less intuitive from the unit circle, but I hope you can see from the unit circle why the tangent of an angle is equal to the sine of the angle over the cosine.
