A table of values, rounded to the nearest hundredth, for the function y = is given for
0≤x≤8.
What is the average rate of change of the function over the interval [2, 7] to the nearest
hundredth?

Step-by-step explanation:

this means the factors of the various terms of x and the constant.

a = 4

b = 1

c = 9

and yes, if there would be negative factors, the signs wold be part of a, b and c too.

overall, this is then used to solve the quadratic equation.

the general solution is

x = (-b ± sqrt(b² - 4ac))/(2a)

Answer:

(8 + 24) ÷ (12 x 4) = 2/3

Step-by-step explanation:

To Find: an expression that has a value of 2/3

Solution :

A. [8 + (24 ÷ 12)] x 4

=  [8 + (2)] x 4

= 10 x 4

= 40

B. (8 + 24) ÷ (12 x 4)

= 32 ÷ 48

= 2 ÷ 3

= 2/3

C. 8 + (24 ÷ 12) x 4

= 8 + 2 x 4

= 8 + 8

= 16

D. 8 + 24 ÷ 12 x 4

8 + 2 x 4

= 8 + 8

= 16

The correct option is :

(8 + 24) ÷ (12 x 4) = 2/3

To form equations from word problems, we can do the following:

We're given:

Question: How many individual tickets were sold? (What is the value of x?)

Here are all the equations we have created:

We can solve for the value of x using systems of equations.

First, isolate y in the first equation:

[tex]x = 36 + y\\y=x-36[/tex]

Now, plug this into the second equation:

[tex]7x + 16y = 574\\7x + 16(x-36)= 574\\7x+ 16x-586= 574\\23x=1150\\\\x=\dfrac{1150}{23}\\\\x=50[/tex]

Therefore, x is equal to 50.

50 individual tickets were sold.

Answer:

Step-by-step explanation:

Answer:

choice 2

Step-by-step explanation:

Arithmetic sequences arare linear. The common difference is the slope. The points given are (3,10) And (5,26).

The slope is the change of y (26-10=16) over the change of x (5-3=2); this is 16/2=8.

The equation of line in slope-intercept form whose slope is given as 8 is y=8x+b.

We may plug in a point to solve for b.

Let's plug in (3,10):

10=8(3)+b

10=24+b

10-24=b

-14=b

So the equation we are lookinlooking for is y=8x-14 which is choice 2.

Answer:

Learning Objective: Use the mean and range to compare the spread and averages.

a) Sarah Mean = 70.9, Katie Mean = 78.9

b) Sarah Range = 15, Katie Range = 25

c) Sentences

- The mean shows, on average, Sarah was 8 seconds quicker than Katie.

- The range shows that Sarah was more consistent with her times. Katie had a larger spread of times which shows she was less consistent.

Step-by-step explanation:

Given:

Sarah's Data Set:

Katie's Data Set:

To Find:

Work:

The mean of a data set is commonly known as the average. You find the mean by taking the sum of all the data values and dividing that sum by the total number of data values. The formula for the mean of a population is [tex]\mu = \frac{{\sum}x}{N}[/tex].

The formula for the mean of a sample is [tex]\bar{x} = \frac{{\sum}x}{n}[/tex].

Both of these formulas use the same mathematical process: find the sum of the data values and divide by the total. For the data values given above, the solution is: [tex]\frac{709}{10} = 70.9[/tex]

Therefore, the mean of Sarah's data set is 70.9.

For Katie's Data Set, [tex]\frac{789}{10} = 78.9[/tex].

Therefore, the mean of Katie's data set is 78.9.

To fill in the summary, we have to use the data we just calculated.

That summary can be found in the answer section.

Answer:

Sarah's mean = 70.9

Katie's mean = 78.9

Sarah's range = 15

Katie's range = 25

The mean shows that on average Sarah was 8 seconds faster than Katie. The range shows that Sarah was more consistent with her times. Katie had a larger spread of times which shows she was less consistent.

Step-by-step explanation:

Identifying the mean time for Katie and Sarah

The mean ( average ) is equal to the sum of the numbers in the data set ( the sum of the swimming times ) divided by the number of values in the data set ( which is given as 10 )

Mean for Sarah : Sum of her swimming times : 79 + 70 + 68 + 75 + 69 + 64 + 69 + 75 + 64 + 76 = 709

Number of values = 10

So mean = 709 / 10 = 70.9 seconds.

Mean for Katie : Sum of her swimming times : 79 + 79 + 76 + 81 + 89 + 76 + 64 + 85 + 82 + 78 = 789

number of values = 10

so mean = 789 / 10 = 78.9

Using this information we can identify what the first to blanks are. The mean shows that on average Sarah was ___ seconds ____ than Katie.

The mean time for Sarah was 70.9 seconds and the mean time for Katie was 78.9 seconds. So on average Sarah was faster and by 8 seconds ( which can be found by subtracting Sarah's mean from Katie's )

Identifying the range

The range is equal to the largest value ( longest swim time ) subtracted by the smallest value ( or quickest swim time )

Range for Sarah : Sarah's highest swim time is 79 seconds and her lowest is 64 seconds.

So her range = 79 - 64 = 15 seconds

Range for Katie : Katie's highest swim time is 89 seconds and her lowest time is 64 seconds

So her range = 89 - 64 = 25

Using this information we can fill out the remaining blanks.

The range shows that ____ was more consistent with her times. ___ had a larger spread of times which shows she was ____ consistent.

The higher the range the less consistent you are vise versa. Katie had a larger range hence, Sarah was more consistent and Katie was less consistent.

Answer:

[tex]f(x)=4\cos(2x)+3[/tex]

Step-by-step explanation:

Using the general equation [tex]f(x)=a\cos(bx+c)+d[/tex], we already know that [tex]a=4[/tex] and [tex]d=3[/tex], but we need to find [tex]b[/tex] from the period:

[tex]\frac{2\pi}{|b|}=\pi\\ 2\pi=b\pi\\2=b[/tex]

Answer:

The volume of the soup can is 602. 88 cubic centimeters

Step-by-step explanation:

Volume of a cylinder = π {r} ^{2} h

Where π = 3.14

r = diameter ÷ 2

r= 8 ÷ 2

r= 4 cm

h= 12 cm

Volume of the soup can= 3.14 × 4 × 4 × 12

= 602. 88 cubic centimeters

we know that

The formula for combinations is

[tex]C=n!/[(n-r)!*r!][/tex]

where

[tex]n[/tex] is the total number of objects you choose from

[tex]r[/tex] is the number that you choose to arrange

in this problem

[tex]n=15[/tex] students

[tex]r=4[/tex] students

[tex]C=15!/[(15-4)!*4!][/tex] → [tex]C=15!/[11!*4!][/tex] → [tex](15*14*13*12*11!)/(11!*4*3*2*1)[/tex]

[tex]C=(15*14*13*12)/(24)[/tex] → [tex]C=1365[/tex]

the answer is

Answer:

y₁ = |x+6|  ; y₂ = 25

Step-by-step explanation:

|x+6| - 12 < 13

⇔ |x+6| < 25

Equation for the given inequality is equals to [tex]y_{1} =| x+ 6| , y_{2} =25[/tex]

" Inequality is defined as the algebraic expression which represents the relation between two variables using sign of inequality."

According to the question,

Given inequality,

|x+6| - 12 < 13

Add both the side of the inequality 12 we get ,

|x+6| - 12+12< 13 + 12

⇒  |x+6| < 25

As represent in the graph equation for the given inequality are,

[tex]y_{1} =| x+ 6| , y_{2} =25[/tex]

Hence, equation for the given inequality is equals to [tex]y_{1} =| x+ 6| , y_{2} =25[/tex].
