Answer

OptionC is correct.

Explanation

The probability of an event is calculated as the number of elements inthat event divided by the total number of elements inthesample space.

For this question, we are asked to find the probability of obtaining a number that is even and a 3 on a 6-sided die.

Number of digits that are even and a 3 on a 6-sided die = 0

Total number of digits on a 6-sided die = 6

Probability of obtaining a number that is even and a 3 on a 6-sided die = (0/6) = 0

Hope this Helps!!!

The Supreme Choice pizza at Pizza Paradise contains:

-) 3 different types of meat

-) 3 different vegetables

There are:

-) 5 types of crust (the customer can select one of them)

-) 6 types of meat

-) 9 vegetables

How many different Supreme choices Pizza can be made? ​

We can use the combinatory operator.

The customer can choose 3 different types of meat out of 6. The number of possible selections is:

For the crust, the customer can choose 1 of 5 possible types. Then, the number of different ways he can choose the crust is simply 5.

For the vegetables, there are 9 in total, and the customer can choose 3 different types. Again, using the combinatory operator, we have:

So we have 20 possible ways of choosing 3 types of meat, 5 possible ways of choosing 1 type of crust, and 84 different ways to choose 3 different vegetables.

For the total number of different Supreme choices Pizza a customer can make, we take the product:

20*5*84 = 8400

That is, there are 8400 different Supreme choices pizza.

Remember that

The speed is equal to divide the distance by the time

speed=d/t

Let

t ----> time spend to go to the conference in hours

s ----> speed trip going

Conference trip

s=360/t ------> equation 1

Return trip

speed=360/(t+3)

speed=s-30

s-30=360/(t+3) ------> equation 2

substitute equation 1 in equation 2

(360/t)-30=360/(t+3)

Multiply both sides by t(t+3) to remove fractions

360(t+3)-30t(t+3)=360t

360t+1,080-30t^2-90t=360t

simplify

30t^2+90t-1,080=0

Solve the quadratic equation

The solutions for t are

t=-7.7 h -----> is not a solution, because is a negative number

t=4.69 hours

Find out the average speed on the return trip

speed=360/(t+3)

speed=360/(4.69+3)

Answer: Volume of a cylinder = 3, 077.20 cubic centimeter

Given data

Diameter of the cylinder = 14cm

Height of the cylinder = 20cm

Radius = diameter / 2

radius = 14/2

radius = 7 cm

x + (x+1)+ (x+2) = -12

3x+3 =-12

Solve for x

3x =-12-3

3x=-15

Divide both sides by 3:

3x/3 = -15/3

x = -5

First integer is -5

Second is integer -5+1 =-4

Third integer -5+2 = -3

The piecewise function f(x) is composed bt two lines: 3/2x + 1 and x - 5. To graph a line, we need to connect two points that lie on the line. In the case of the first line, we can use its endpoints x = -4 and x = 0.

Substituting x = -4 into the equation of the first line, we get:

Then, the point (-4, -5) lies on the first line.

Substituting x = 0 into the equation of the first line, we get:

Then, the point (0,1) lies on the first line.

In the case of the second line, the endpoints x = 1 and x = 3.

Substituting x = 1 into the equation of the second line, we get:

Then, the point (1,-4) lies on the second line.

Substituting x = 3 into the equation of the second line, we get:

Then, the point (3,-2) lies on the second line.

Connecting these points with two different lines as stated before, we get the graph of f(x) as follows:

We have the general rule for a rotation of 90° counterclockwise:

and the general rule for a y=-x reflection is:

In this case, we have the points R=(2,-2), S=(5,-1) and T=(3,-5).

Then, we first have to use the 90° rotation on all points:

Now we use the y=-x reflection on our new points:

therefore, the final points after the transformations are:

R''=(2,2)

S''=(5,1)

T''=(3,5)

15 can vary by 2%, this means that the range of values you can observe are 2% below 15 and 2% above 15.

First, you have to determine how much does the percentage represents with regards to the value of reference. To do so, you have to calculate the 2% of 15:

-Multiply 2 by 15 and divide the result by 100

The 2% of 15 is 3, which means that the range of values you are looking for is 3 units below 15 and 3 units above.

The minimum value of the range: subtract 3 to 15

The maximum value of the range: add 3 to 15

The range of allowable values is [12;18]

We want to know then it will land on the desert, in other words, when the height is equal to zero, then

Then we must solve that quadratic equation, to solve it let's first divide all by 16

Because it's an easier equation to solve and the solution is the same. Now we can apply the quadratic formula

Plug the values

We can ignore the other solution because it's negative and negative time is not a valid solution. Therefore, 30 seconds after its launch, the rocket will land in the desert

The volume of a sphere can be calculated using this formula:

Where "r" is the radius of the sphere and "V" is the volume of the sphere.

If you solve for "r", you get this new formula:

In this case you know that:

Therefore, you can substitute this value into the second formula and then evaluate, in order to find the radius of this sphere:

The answer is:

Given that -50=3(15)+b

expand

-50 - 45 = 45 - 45 + b

-95 = b

b = -95

Step-by-step solution;

We begin by calculating the mean of the data set as follows;

We now round the mean to two decimal places and we have;

Next we subtract the mean from EACH value in the data set. the individual results are the "deviation from the mean."

After that we square each deviation from the mean, and then add them all up.

This is effectively explained by the formula for the variance which is;

Now we can refine the formula as shown below;

We can round this to 2 decimal places and the variance therefore is;

Let us find the slope first

The equation can be found as follows using the points (0 ,1)

For the sinusoidal function:

we have that:

A represents the amplitude

2pi/B represents the Period

C is the phase shift

D is the vertical shift.

In this case, we have the following equation:

then, the amplitude is A = 1.

For the period, we have the following:

thus, the period is pi.

Finally, notice that C = -pi/2, thus, the phase shift is -pi/2

To add 2 algebraic fractions we must make their denominators the same

Then we must have the LCM of both denominators

Since the denominators area (x + 2) and (3x + 6), then

We can take 3 as a common factor from the 2nd denominator

Then the LCM of the 2 denominators is 3(x + 2)

Now we can change the first denominator to 3(x + 2) by multiplying up and down by 3

Since m is the number of miles driven and company A charges a base price of $56 plus a charge of $0.25 per mile, we can write the following equation:

Again, since m is the number of miles driven and company B charges a base price of $45 plus a charge of $0.58 per mile, we can write the following equation:

The cost of renting a car from both companies will be the same when:

Then, we solve the following equation for m:

Therefore, the cost of renting a car from both companies will be the same at 33.33 miles.

I will write an equation for each statement

the factory produces atleast twice as many low-grade as high-grade shoes.

maximum possible production is 500 pairs of shoes.

where x is the number of high-grade shoes and y the number of Low-grade shoes

and replace on the first equation

the value of x must be less than or equal to 166.6 but we must use whole numbers so it will be 166

now replace on

to find y

suppose the operation makes a profit of 2.00 dollars per a pair of shoes on high-grade shoes and 1.00 dollar per pairs of shoes on low-grade shoes.

where P is the profit

and replce x and y to find the value of the profit

The maximun profit must be $666

Percentage decrease in price

Original price = $60

Find 15% of 60

Then

10% of 60 is $6

5% of 60 is $6/2 = $3

In consecuence 15% of $60 is 6+3 = $9

Then precent decrease in price is $9

And New price is 60-9 = $51
