Is the fraction 1/4 equal to 2.5

False, The claim that the range of the data set (16, 8, 16, 14, 10, 9, 8, 11, 12, 13, 18) is 97 is false. The actual range is the difference between the largest and smallest values, which is 10.

The task is to determine whether the statement that the range of the provided data set is 97 is true or false. First, let's define the range. It is the difference between the smallest and largest numbers in a data set. Looking at the data provided: 16, 8, 16, 14, 10, 9, 8, 11, 12, 13, 18, we find the smallest value to be 8 and the largest to be 18.

To calculate the range, we subtract the smallest number from the largest: 18 - 8 = 10. Consequently, the initial claim that the range is 97 is false. The correct range of this data set is, in fact, 10.

The given statement the range of the set of data below is 9 is false.

The correct answer is False.

To find the range of a set of data, we subtract the smallest value from the largest value.

Step 1: Identify the smallest and largest values in the data set.

  Smallest value: 7

  Largest value: 18

Step 2: Calculate the range.

  Range = Largest value - Smallest value

  Range = 18 - 7

  Range = 11

Step 3: Compare the calculated range with the given range.

  Given range = 9

  Calculated range = 11

Since the calculated range (11) does not match the given range (9), the statement "The range of the set of data below is 9" is False.

The range of a data set measures the spread or dispersion of the data. It is calculated by finding the difference between the largest and smallest values in the data set. In this case, the smallest value is 7 and the largest value is 18. Therefore, the range is 18 - 7 = 11. This contradicts the given range of 9, making the statement false. In summary, the correct answer is False, and the range of the given data set is 11.

Answer:

8 books; 4 from each shelf

Step-by-step explanation:

let x represent equal number of books from each shelf

from shelf A = 40 -x

from shelf B = 16 -x

shelf A has 3 times as many books than shelf B

3(16- x) = 40 -x

48 -3x = 40 -x

48 - 40 = -x + 3x

8 = 2x

x = 4

altogether she borrowed 4 + 4 = 8 books

[tex]\bf \begin{array}{ccll} books&price\\ \cline{1-2} 8&y\\ 3&x \end{array}\implies \cfrac{8}{3}=\cfrac{y}{x}\implies 8x=3y\implies x=\cfrac{3}{8}y[/tex]

Final answer:

To determine the price of 3 books when given the cost of 8 similar books, you divide the total cost by 8 to find the price per book, then multiply this price by 3.

Explanation:

The student asked: At a bookstore, 8 similar books cost y dollars. What is the price of 3 such books? To find the price of one book, we divide the total cost y by the number of books, which is 8. Let's call the price of one book x. So, x = y/8.

To find the price of 3 books, we multiply the price of one book by 3. Hence, the price of 3 books would be x times 3 or (y/8) times 3, which can be simplified to 3y/8.

Thus, the price of 3 such books is 3y/8 dollars.

The integer represents her average score for 5 rounds will be 4.

Arithmetic mean is the best central measure available for representing the values of a data set.  It is also called average of the values of the considered data set. It serves as one representation of the values of the data set. If for a data set, only its average is given, then we can't say much about the values of the data set. Average provides ill information in case of skewed data.

WE have given that 5 rounds of a game, jill scored -3, 8, 9, -7, and 13.

Then total number of score = - 3+8+9+-7+13

= 20

The total number of round in game = 5

Therefore,

Average =  the total number of score/ number of rounds

Average = - 3+8+9+-7+13 / 5

Average = 20/5

Average = 4

Hence, the integer represents her average score for 5 rounds will be 4.

I think the last one. Sorry if I’m wrong. Minus year 2 and 5

Answer:

Option. A is the correct option.

Step-by-step explanation:

The yearly attendance at a ballpark is shown in the table attached.

We have to describe the average rate of change in attendance from year 2 to year 5.

Since rate of change in the attendance will be described by [tex]\frac{\text{Difference in attendance}}{\text{Difference in years}}[/tex]

Therefore, average change in attendance = [tex]\frac{\text{Attendance in year 5 - attendance in year 2}}{\text{5-2}}[/tex]

= [tex]\frac{333.7-298.3}{5-2}=\frac{35.40}{3}[/tex]

Answer:

4/9

Step-by-step explanation:

since they are independent

p(ab)=p(a/b)=p(a)*p(b)

1/5=p(a)*9/20

p(a)=[tex]\frac{\frac{1}{5} }{\frac{9}{20} }  = 4/9[/tex]

Given that two events are independent, the probability of one event given the other is the same as the probability of the event itself. Therefore, the probability of event A is 1/5.

In probability, the concept of independence plays a crucial role. If two events, A and B, are independent, then the probability of event A occurring, given that event B has already occurred, is the same as the probability of event A.

In your case, P(A|B) = P(A). So, P(A) = P(A|B) = 1/5.

Micha's scale model of the Empire State Building is 7.62 centimeters tall

To determine the height in centimeters of Micha's scale model of the Empire State Building, we use the given scale where 1 cm represents 50 meters.

First, we find the scale factor for the actual height of the Empire State Building, which is 381 meters.

Using the scale, the calculation is as follows:

Actual height of Empire State Building = 381 m.

Scale ratio = 1 cm : 50 m.

Height of model in cm = Actual height (in meters) \/ Scale ratio (meters per cm).

Height of model in cm = 381 m / 50 m/cm.

Height of model in cm = 7.62 cm.

Therefore, the height of Micha's model is 7.62 centimeters.

Step-by-step explanation:

Use the trig function Cosine to find the length of the ramp. The cosine function is defined as the ratio adjacent side over hypotenuse. The base 20 is the adjacent side to the angle 14 while the length of the ramp is the hypotenuse. Using the function we write, cos 14 = 20 / x. Solve for x.

Cos 14 = 20 / x

x*Cos 14 = 20

x = 20 / cos 14

The dimensions of the rectangle are length = 12 cm and width = 7 cm by solving equations of given the width of a rectangle is 5 cm less than the length and the perimeter is 38 cm.

Let's represent the length of the rectangle as "L" and the width as "W".

According to the given information:

The width is 5 cm less than the length, so we can write W = L - 5.

The perimeter of a rectangle is given by the formula P = 2(L + W),

where P is the perimeter, L is the length, and W is the width.

In this case, the perimeter is 38 cm, so we have

38 = 2(L + W).

Now we can use these equations to find the dimensions of the rectangle.

Substitute the value of W from the first equation into the second equation:

38 = 2(L + (L - 5))

Simplify the equation:

38 = 2(2L - 5)

38 = 4L - 10

Add 10 to both sides:

48 = 4L

Divide both sides by 4:

L = 12

Now we can substitute the value of L into the first equation to find the width:

W = L - 5

W = 12 - 5

W = 7

Therefore, the dimensions of the rectangle are length = 12 cm and width = 7 cm by solving equations of given the width of a rectangle is 5 cm less than the length and the perimeter is 38 cm.

The value of the function f(3) when, given that differencial function f'(x) = 6lnx and f(2) = -3.682, is 1.7748.

Integration is the operation which is used to find the original function from its darivative form.

The differencial function is given that

[tex]f'(x) = 6\ln x[/tex]

Integrate this function, with respect to the x,

[tex]f(x) =\int { 6\ln x} \, dx\\f(x) =6(\int { \ln x} )\, dx\\f(x) =6(x\ln x-\int { 1} \, dx)+C\\f(x) =6(x\ln x-x)+C\\f(x)=6x(\ln x-1)+C[/tex]

The value of function at 2 is,

[tex]f(2) = -3.682[/tex]

Put this value in the above equation as,

[tex]f(2)=6(2)(\ln (2)-1)+C\\-3.682=12(0.6931-1)+C\\-3.682=-3.682+C\\0=C[/tex]

Hence the value of constat is 0. Thus, the  value of function at 3 is,

[tex]f(3)=6(3)(\ln (3)-1)+0\\f(3)=18(1.0986-1)\\f(3)=1.7748[/tex]

Hence, the value of the function f(3) when, given that differencial function f'(x) = 6lnx and f(2) = -3.682, is 1.7748.

Answer:

See below.

Step-by-step explanation:

The graph of ƒ(x) = x² is the red parabola in Figure 1.

Step 1. Vertex of g(x)

g(x) = (x – 1)² + 2

The graph of g(x) will be a parabola like that of ƒ(x) translated one unit to the right and two units up.

The vertex of ƒ(x) is at (0, 0), so the vertex of g(x) is at (1, 2). See Figure 1.

Step 2. Calculate two more points

(a) Try x = 0

g(0) = (0 – 1)² + 2 = 1² + 2 = 1 + 2 = 3

So, there is a point at (0, 3).

(b) Try x = 2

The axis of symmetry is a vertical line passing through the vertex at x = 1. We have calculated a point one unit left of the axis (at x = 0), so let's calculate a point one unit to the right, at x = 2.

g(2) = (2 – 1)² + 2 = 1² + 2 = 1 + 2 = 3

So, there are points at (2, 3) and (1,3). See Figure 2.

Step 3. Sketch the graph of g(x)

Draw a smooth curve through the three points. Extend the arms of the parabola vertically so the graph has the same shape as that of ƒ(x).

Your graph should look like the blue parabola in Figure 3.

Answer:

[tex]a_{n}[/tex] = 8 - 11n

Step-by-step explanation:

These are the terms of an arithmetic sequence with n th term

[tex]a_{n}[/tex] = a + (n - 1)d

where a is the first term and d the common difference

here a = - 3 and

d = - 14 - (- 3) = - 14 + 3 = -11, thus

[tex]a_{n}[/tex] = - 3 - 11(n - 1)

                        = - 3 - 11n + 11

                        = 8 - 11n

The explicit formula for the sequence -3, -14, -25, -36, ... is An = -11n + 8.

The student asked for an explicit formula for the sequence -3, -14, -25, -36, and so forth. We notice that each term decreases by 11 from the previous term. To find an explicit formula, we can use the arithmetic sequence formula which is given by An = A1 + (n - 1)d, where An is the n-th term, A1 is the first term, n is the term number, and d is the common difference between the terms.

For the given sequence, the first term A1 is -3 and the common difference d is -11. Substituting these values into the formula, we get An = -3 + (n - 1)(-11). We can simplify this to An = -3 - 11n + 11, which simplifies further to An = -11n + 8. Hence, the explicit formula for the given sequence is An = -11n + 8.
