x1= (-b+VD)/2a

= (-3+V45)/2×9

= (-3+3V5)/18

x2=(-b-VD)/2a

=(-3-3V5)/18

=(-1-V5)/6

The interquartile range for the given data is 1 quesadilla.

The interquartile range is a measurement of a data set's "middle fifty." A range is a measurement of where a set's beginning and end are located.

To get the interquartile range, we must know the first and third quartiles. To find those, we need to know the median of the data.

There are 11 data points, so we can cross out 5 numbers on the left and cross out 5 numbers on the right. That leaves a median of 1.

Since we know the median is 1, we can find the first quartile by finding the median of the following numbers:

0, 0, 1/4, 1/2, 1/2  (any number less than 1).

There are five numbers, so cross out two numbers from the left and cross out two numbers from the right. We are left with the first quartile of 1/4.

Now that we have the first quartile, we need to find the third quartile. Since the median was actually the first "1" in the data set, the third quartile will be the median of the numbers to the right of that "

1: 1, 1, 5/4, 2, 2.

Cross out the leftmost two numbers, and cross out the rightmost two numbers. We are left with the third quartile of 5/4.

Now that we have both the third and first quartiles, we can find the interquartile range! The IQR is calculated by finding the third quartile minus the first quartile.

5/4 - 1/4 = 4/4 = 1.

Therefore, the interquartile range is 1 quesadilla.

Answer:

x = -3/2

Step-by-step explanation:

x + 3 + d  = 2x + 1              First term plus common difference = 2nd term

x -2 = d

x + 3 + 2d = 5x+2              First term + 2 d = third term    re-arrange:

4x-1 = 2d                            sub in the definition of d from above

4x -1 = 2 (x-2)

4x-1 = 2x-4

2x = -3

x = -3/2

If x+3, 2x+1, and 5x+2 are consecutive terms of an arithmetic sequence then x is -3/2.

Sequence is an enumerated collection of objects in which repetitions are allowed and order matters.

The sequence in which consecutive terms will have common difference is called as Arithmetic sequence.

x+3, 2x+1, and 5x+2

The common difference between first term and second term

d=2x+1-x-3

d=x-2

The common difference between second term and third term

5x+2-2x-1=d

3x+1=d

Now plug in d value

3x+1=x-2

Subtract x from both sides

3x-x=-3

2x=-3

Divide both sides by 2

x=-3/2

Hence, if x+3, 2x+1, and 5x+2 are consecutive terms of an arithmetic sequence then x is -3/2.

The option A is showing the domain ans the range of the function F(x) as inverse of F(x).

In mathematics, the inverse function of a function f (also called the inverse of f) is a function that undoes the operation of f. The inverse of f exists if and only if f is bijective, and if it exists, is denoted by [tex]{\displaystyle f^{-1}.}[/tex]

Here in the graph we can see that the option A has the clear range of the function.

It is not a valid sample because it is not a random sample of the population.

Explanation:

The researcher should have randomly selected the participants, either by picking names out of a hat, using a random number table, or some kind of computer software to pick the names. Letting the first 8 people form the sample is very likely not representative of the population at large. We have a lot of bias here. Therefore, this is not a valid sample.

Answer:

Each geometry book costs $6, each algebra book costs $8.

Let a=cost of one algebra book and g=cost of one geometry book. We have:

2a + 3g = 34-------->6a + 9g = 102

3a + 2g = 36-------->6a + 4g = 72

-------------------

5g = 30

g = 6

2a + 3(6) = 34

2a + 18 = 34

2a = 16--->a = 8

Question: John paid $34 for two algebra and three geometry books. He paid $36 for three algebra and two geometry books. What is the cost of each book?

Answer: The cost of each algebra book is $8 and the cost of each geometry book is $6.

Step-by-step explanation:

a= algebra book cost

g= geometry book cost

Here's what we know:

2a + 3g = 34 (the 2 alg and 3 geo comes to $34)

3a + 2g = 36 (the 3 alg and 2 geo comes to $36)

This is a classic elimination method problem. I suggest that we multiply the first equation by -2 and the second by 3. This way, we can eliminate the variable g and still keep the other parts of the problem in the positive range:

-4a - 6g = -68

9a + 6g = 108

-------------------

5a = 40

Divide by 5:

a = 8

Now to solve for g:

2 * 8 + 3g = 34

16 + 3g = 34

3g = 18

g = 6

check (by using the second equation):

3 * 8 + 2 * 6 = 36

24 + 12 = 36

Step-by-step explanation:

First, find the missing side length (DE) by using Pythagoras' Theorem:
