Option D is correct the answer. The average rate of change over the interval 1 < x < 5 is greater than the average rate of change over the same interval for the function g(x) = 1. 8x2 is k(x) = 2x^2

The average rate of change:

Given a function y, the average rate of change S of y=f(x)  in an interval (xs,xf) will be given by the following equation:

[tex]S=\frac{f(xf)-f(xo)}{xf-xo}[/tex]

In this problem, we have that:

Interval (1,5), so xf=5,xo=1

Then

[tex]S=\frac{f(5)-f(1)}{4}[/tex]

All options are compared to g(x).

[tex]g(x)=1.8x^{2}[/tex]

g(5) = 1.8*(5)^2 = 45

g(1) = 1.8*(1)^2 = 1.8

[tex]S=\frac{45-1.8}{4} =10.8[/tex]

A.=f(x) = x^2

f(5) = 5^2 = 25

f(1) = 1^2 = 1

[tex]S=\frac{25-1}{4} =6.25[/tex]

Smaller than 10.8, so this is not the answer.

B.=g(x) = 1.2x^2

g(5) = 1.2*(5)^2 = 30

g(1) = 1.2*(1)^2 = 1.2

[tex]S=\frac{30-1.2}{4} =7.2[/tex]

Smaller than 10.8, so this is not the answer.

C.=h(x) = 1.5x^2

h(5) = 1.5*(5)^2 = 37.5

h(1) = 1.5*(1)^2 = 1.5

[tex]S=\frac{37.5-1.5}{4}= 9[/tex]

Smaller than 10.8, so this is not the answer.

D.=k(x) = 2x^2

k(5) = 2*(5)^2 = 50

k(1) = 2*(1)^2 = 2

[tex]S=\frac{50-2}{4} =12[/tex]

Greater than 10.8, this is the answer.

There are 8 players who weigh between 169 and 194 pounds.

To answer this question, we can look at the box plot to understand the distribution of weights on the football team. The box plot shows us the minimum, maximum, median, and quartiles of the team's weights. The left quartile is 169 pounds, and the right quartile is 194 pounds. This means that 25% of the team's players weigh between 169 and 194 pounds. Since the team has 36 players, 25% of 36 is 9. However, since we are looking at the number of players between 169 and 194 pounds, we need to subtract 1 since the right quartile of 194 pounds is included in the number of players. Thus, there are 8 players who weigh between 169 and 194 pounds.

Answer:

The x-axis interval of 39 to 65 has the smallest rate of change.

Step-by-step explanation:

See the attached worksheet.  The interval of x that results in the least change in y can be visually seen by plotting the points and drawing a curve.  The curve begins to flatten as x increases.  So the smallest rate of change is between the last two points, x = 39 to 65.

This can also be calculated by finding the change in y per a change in x.  The table in the graph confirms the earlier observation.  Dx and Dy represent the "delta," or difference, D,  between the x (Dx) and y(Dy) values.  The rate of change is calculated as Dy/Dx, or the change in y divided by the change in x.  The results confirm that the 39 to 65 segment is the smallest, at 0.15.

We must switch from rectangular to cylindrical coordinates in the provided problem. (let r ≥ 0 and 0 ≤ θ ≤ 2π.)

A)(−7, 7, 7)

Given rectangular coordinates(x, y, z) =(−7, 7, 7)

The cylindrical coordinates are (r, θ, z)

As a result, we determine each value of r and θ  separately.

r = √x²+y²

r = √(-7)²+(7)²

r = √49+49

r = √98

θ = tan⁻¹ (y/x)

θ =tan⁻¹  (7/-7)

θ =tan⁻¹  (-1)

θ = -π/4

So cylindrical coordinate = (r, θ, z) = (√98, -π/4, 7)

B) (-7,7√3,1)

Given rectangular coordinates(x, y, z) = (-1,1,1)

The cylindrical coordinates are (r, θ, z)

As a result, we determine each value of r and θ  separately.

r = √x²+y²

r = √(-7)²(7√3)²

r = √49+147

r = √196

r = 14

θ = (y/x)

θ = (7√3/-7)

θ = (-√3)

θ = -π/3

Answer: y=-1/2x+4

Step-by-step explanation:

find the slope of the line given which would be-2/4 which simlifys down to 1/2 then add your b (y intercept) and that wold be 4.  

The minimum value, Q1, Median, Q3 and maximum value of the data are 10,15,21.5, 23.5 and 27 respectively. The box-and-whisker plot of data is attached

Given: 21,27,22,22,25,14,16,10

Arrange the data in ascending or descending order:

10,14,16,21,22,22,25,27

The minimum value = 10. The maximum value = 27

Find the median. The median is the value in the middle. The median values are 21 and 22. Thus:

10,14,16,21,22,22,25,27

Median (Q2) = (21+22)/2 = 21.5

Consider the values to the left of the median with one of the median numbers included (since we have two numbers in the middle): 10,14,16,21

Median = (14+16)/2 = 15

Thus, Q1 = 15

Also, consider the values to the right of the median with one of the median numbers included: 22,22,25,27

Meadian = (22+25)/2 = 23.5

Thus, Q3 = 23.5

Answer: The y-intercept is 14

Step-by-step explanation:

The slope intercept is y=mx+b

since we already have the slope, we can write this as

y=-5x+b

substitute the points of (3,-1) into the equation and solve for b

-1=-5(3)+b

-1=-15+b

b=14

The y-intercept is 14

The y-intercept of the line is 14.

The equation of a line is given by:

y = mx + c

where m is the slope of the line and c is the y-intercept.

Example:

The slope of the line y = 2x + 3 is 2.

The slope of a line that passes through (1, 2) and (2, 3) is 1.

We have,

Slope = -5

The line passes through the point (3, -1).

The equation of the line is y = mx + c.

y = -5x + c

(3, -1) = (x, y)

-1 = -5 x 3 + c

-1 = -15 + c

-1 + 15 = c

c = 14

Thus,

The y-intercept is 14.

To Find : size of angle x

Solution:

Area of ΔABC = (1/2) * BC * AC

=> (1/2) * BC * AC = 42

=> (1/2) * 6 * AC = 42

=> AC = 14 cm

BD = BC + CD

=> 22 = 6 + CD

=> CD = 16 cm

Tan x = AC /CD

=> Tan x = 14/16

=> Tanx = 7/8

=> x = Tan⁻¹(7/8)

=> x = 41.186°

The size of the angle is - 41. 186°

    area of triangle ABC = 1/2 * BC * AC

    or, 1/2 *BC * AC = 42

     or, 1/2 * 6 * AC = 42

     or, 3 * AC = 42

divide both sides by 3,

        AC = 14 cm

     BD = BC + CD

or, 22 = 6 + CD

or, CD = 16 cm

   tan x = [tex]\frac{AC}{CD}[/tex]

or, tan x = [tex]\frac{14}{16}[/tex]

or, tan x = [tex]\frac{7}{8}[/tex]

A  conditional probability p(b | a) is equal to its marginal probability p(b) if A and B are independent.

The likelihood that any two events will occur is equal to the sum of the probabilities of each event separately, less the probability that the two occurrences will meet. However, if two occurrences are incompatible with one another, then there is a zero probability of the two events intersecting, therefore the likelihood that either one or the other will occur is equal to the sum of the two individual probabilities.

To calculate conditional probability, use the following formula:

p( b | a ) = p( a ∩ b )/ p(a)

It is known that if two events A and B are independent, then p(a ∩ b) = p (a) . p(b)

So, p(b | a) = [p (a) . p(b)]/p(a) = p(b)

Thus, it is concluded that a conditional probability p(b | a) is equal to its marginal probability p(b) if A and B are independent.
