Answer:

You will drive 5 kilometers a second

Step-by-step explanation: To determine how many kilometers you will drive in one second, you need to take the data already given to you and use it to solve this problem. First you need to take the amount of kilometers you drive in 20 seconds which is 100, and divide it by 20 to find out the answer to this problem.

Answer:

C. $y=\sqrt{2x-6}+1$

Step-by-step explanation:

From the graph of the function, we can see that the domain of the function is $x\ge 3,$ the range of the function is $y\ge 1.$

Consider the parent function $y=\sqrt{x}.$

The domain of this function is $x\ge 0,$ the range of this function is $y\ge 0.$

The function $y=\sqrt{2x-6}+1$ has

the domain

$2x-6\ge 0\\ \\2x\ge 6\\ \\x\ge 3$

and the range

$y\ge 0+1\\ \\y\ge 1$

All other options have different domain, or the range, or both the domain and the range.

Answer:

Step-by-step explanation:

The easiest way to start is to do this problem is to start changing the 3/4 cup to a decimal

3/4 = 0.75

Now divide that into 11. What you are interested in is the remainder.

11/0.75 = 14.66667

He can make 14 whole pizzas.

He has 0.66667 of a cup left over which is less than 3/4 (or 0.75) so he does not have enough for another pizza.

So the answer is 0.66667 which is 2/3 of a cup is left over.

The numbers 1, 2, 3, 4, and 5 are written on slips of paper, and 2 slips are drawn at random one at a time without replacemen

<h2>Answer:</h2>

(a)

The probability is : 1/2

(b)

The probability is : 1/2

<h2>Step-by-step explanation:</h2>

The numbers 1, 2, 3, 4, and 5 are written on slips of paper, and 2 slips are drawn at random one at a time without replacement.

The total combinations that are possible are:

(1,2) (1,3) (1,4) (1,5)

(2,1) (2,3) (2,4) (2,5)

(3,1) (3,2) (3,4) (3,5)

(4,1) (4,2) (4,3) (4,5)

(5,1) (5,2) (5,3) (5,4)

i.e. the total outcomes are : 20

(a)

Let A denote the event that the first number is 4.

and B denote the event that the sum is: 9.

Let P denote the probability of an event.

We are asked to find:

P(A|B)

We know that it could be calculated by using the formula:

$P(A|B)=\dfrac{P(A\bigcap B)}{P(B)}$

Hence, based on the data we have:

$P(A\bigcap B)=\dfrac{1}{20}$

( Since, out of a total of 20 outcomes there is just one outcome which comes in A∩B and it is: (4,5) )

and

$P(B)=\dfrac{2}{20}$

( since, there are just two outcomes such that the sum is: 9

(4,5) and (5,4) )

Hence, we have:

$P(A|B)=\dfrac{\dfrac{1}{20}}{\dfrac{2}{20}}\\\\i.e.\\\\P(A|B)=\dfrac{1}{2}$

(b)

Let A denote the event that the first number is 3.

and B denote the event that the sum is: 8.

Let P denote the probability of an event.

We are asked to find:

P(A|B)

Hence, based on the data we have:

$P(A\bigcap B)=\dfrac{1}{20}$

( since, the only outcome out of 20 outcomes is: (3,5) )

and

$P(B)=\dfrac{2}{20}$

( since, there are just two outcomes such that the sum is: 8

(3,5) and (5,3) )

Hence, we have:

$P(A|B)=\dfrac{\dfrac{1}{20}}{\dfrac{2}{20}}\\\\i.e.\\\\P(A|B)=\dfrac{1}{2}$
