Answer is -16

Step-by-step explanation:

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]

= 11.80 thousands per year

≈ 11800 people per year

Therefore, there is an average rate of change of 11800 people per year from year 2 to year 5.

[tex]\sqrt{13}[/tex]

Step-by-step explanation:

Given the vector < a, b > then the magnitude is

[tex]\sqrt{a^2+b^2}[/tex], thus

| (- 3, 2) | = [tex]\sqrt{(-3)^2+2^2}[/tex] = [tex]\sqrt{9+4}[/tex] = [tex]\sqrt{13}[/tex]

The length of the magnitude of the given vector <-3,2> is:

                        [tex]\sqrt{13}[/tex]

We know that for any vector of the type: <a,b>

The magnitude of the length of the vector is given by the formula:

[tex]|<a,b>|=\sqrt{a^2+b^2}[/tex] [tex]\sqrt{13}[/tex]

Here we are given the vector as: <-3,2>

i.e. a= -3

and  b=2.

This means that the length of the magnotude of the vector is given by:

[tex]|<-3,2>|=\sqrt{(-3)^2+(2)^2}\\\\i.e.\\\\|<-3,2>|=\sqrt{9+4}\\\\i.e.\\\\|<-3,2>|=\sqrt{13}[/tex]

Hence, the answer is:  [tex]\sqrt{13}[/tex]

Step-by-step explanation:

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.

-3+8+9+-7+13 divided by 5 which is 4

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.

Answer:

[tex] C.676.01 \: {in}^{3} [/tex]

step-by-step explanation :

The volume of the composite solid = volume of the cuboid + volume of the rectangular pyramid

Volume of the cuboid

[tex] = L \times B \times H[/tex]

where

[tex]L = 9 \: inches \\ B = 9 \: inches \\ H = 5 \: inches[/tex]

By substitution,

[tex] \implies \: V = 5 \times 9 \times 9[/tex]

[tex]\implies \: V = 405 \: {in}^{3} [/tex]

Volume of rectangular pyramid

[tex] = \frac{1}{3} \times base \: area \times height[/tex]

[tex]\implies \: V = \frac{1}{3} \times \:( L \times B ) \times \: H[/tex]

[tex] L = 9 \: inches \\ B = 9 \: inches \\ s= 11 \: inches[/tex]

We use the Pythagoras Theorem, to obtain,

h²+4.5²=11²

h²=11²-4.5²

h=√100.75

h=10.03

By substitution,

[tex]\implies \: V = \frac{1}{3} \times \:( 9 \times 9 ) \times \:10.0374[/tex]

[tex]\implies \: V =271.0098 \: {in}^{3} [/tex]

Hence the volume of the the composite solid

[tex]=676.01\: {in}^{3} [/tex]

Answer:

The correct answer is option C.  676.01 in^3

Step-by-step explanation:

It is given a composite solid.

Total volume = volume of cuboid + volume of pyramid

To find the volume of cuboid

Volume of cuboid = Base area * height

Base area = side * side = 9 * 9

Volume = 9 * 9 * 5 = 405 in^3

To find the volume of pyramid

Before that we have to find the height of pyramid

Height² = Hypotenuse² - base² = 11² - 4.5² = 100.75

Height = √100.75 = 10.03

Volume of pyramid = 1/3(base area * height)

  = 1/3(9 * 9 * 10.03) = 271.01 in^3

To find the volume of solid

Volume of solid =  volume of cuboid + volume of pyramid

 = 405 + 271.01 = 676.01 in^3

Therefore the correct answer is option C.   676.01 in^3

The number of hours in a day is correctly measured in the tens, as a day comprises of 24 hours. This measurement is a human invention rather than a natural observation. Hence true.

The question you've asked is whether the number of hours in a day is measured in the tens. The answer is True. There are 24 hours in a complete day. This measure is not something that naturally exists but rather is a human invention for the purpose of timekeeping. The Babylonians are credited with dividing a circle into 360 degrees, and they chose 24 as it divides neatly into 360, which allows for hours of a reasonable length that can be measured throughout the day. Notably, all days do not have exactly 12 hours of day and 12 hours of night except at the equator, and this occurs every day of the year. Other locations may experience nearly equal amounts of day and night during the equinoxes.

When we say that the number of hours in a day is more than seven hours, we are observing a fact about the number of hours in a day, which is significantly more than seven hours since a full day consists of 24 hours.

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.

Answer:

the equation is 0 = -3x - 5 + x^2

Answer:  The correct option is

(A) [tex]0=-3x-5+x^2.[/tex]

Step-by-step explanation:  We are given to select the correct quadratic equation that has an a-value of 1, b-value of -3 and c-value of -5.

We know that

a general quadratic equation is of the following form :

[tex]ax^2+bx+c=0,~~a\neq0,[/tex]

where a is the coefficient of x²,

b is the coefficient of x

and

c is the constant term.

For the given equation, we get

the coefficient of x², a = 1,

the coefficient of x, b = -3

and

the constant term, c = -5.

Therefore, the required equation is

[tex]1\times x^2+(-3)\times x+(-5)=0\\\\\Rightarrow 0=-3x-5+x^2.[/tex]

Thus, (A) is the correct option.

x =7

so you length is 7

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.

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.

EXPLANATION

The given equation is:

[tex] {x}^{3} - 27 = 0[/tex]

We add 27 to both sides of the equation to get:

[tex] {x}^{3} = 27[/tex]

We write 27 as number to exponent 3.

[tex]{x}^{3} = {3}^{3} [/tex]

The exponents are the same.

This implies that, the bases are also the same.

Therefore

[tex]x = 3[/tex]

The answer is:

The equation has only one root (zero) and its's equal to 3.

[tex]x=3[/tex]

We are working with a cubic equation, it means that there will be three roots (zeroes) for the equation.

To solve the problem, we need to remember the following exponents and roots property:

[tex]\sqrt[n]{x^{m} }=x^{\frac{m}{n} }[/tex]

[tex](a^{b})^{c}=a^{b*c}[/tex]

So, we are given the equation:

[tex]x^{3}-27=0[/tex]

Isolating x we have:

[tex]x^{3}=27\\\\\sqrt[3]{x^{3}}=\sqrt[3]{27}\\\\x^{\frac{3}{3} }=\sqrt[3]{(3)^{3} }\\\\x^{\frac{3}{3} }=3^{\frac{3}{3} }\\\\x=3[/tex]

Hence, we have that the equation has only one root (zero) and its's equal to 3.
