The two terms of each arithmetic sequence [tex]a_{4}[/tex] = 8 [tex]a_{7}[/tex] = 20 are d = 4 and a = -4.

[tex]a_{4}[/tex] = 8

8 = a +3d.............1

[tex]a_{7}[/tex] = 20

20 = a + 6d...........2

equating equation 1 and 2

8 = a +3d

20 = a + 6d

d = 12/3

d = 4...............3

from equation 3

8 = a + 12

a = -4

An ordered group of numbers with a shared difference between each succeeding word is known as an arithmetic sequence. For instance, the common difference in the arithmetic series 3, 9, 15, 21, and 27 is 6.

Arithmetic sequences are sequences containing these patterns. The distance between succeeding terms in an arithmetic series is always the same. The difference between consecutive words is always two, hence the sequence 3, 5, 7, 9... is arithmetic.

An explicit formula that states a = d (n - 1) + c, where d is the common difference between succeeding words, and c = a1, can be used to establish an arithmetic sequence.

The sampling technique Greg used is stratified sampling.

Stratified sampling is used when the population is more heterogeneous. Then we divide the population into subgroups or strata which will be more homogeneous and take samples from each strata. This will ensure the equal representation from each group in population. Stratified sampling helps to reduce the variability of the estimates also.

Here the population of current season ticket holders consist both for men's basketball games and women's basketball games. So Greg considered both as separate subgroups of the population and collected random samples of size 100 from each group. This technique for sampling is known as stratified sampling.

The length of the line segment XY which was bisected at point M is;

1) 32

2) 6

1) From the given line segments, it is clear that XM is congruent to YM since M bisects XY. Thus;

XM = YM and XM + YM = XY

We are given that;

XM = 3x + 1

YM = 8x - 24

Thus;

3x + 1 = 8x - 24

8x - 3x = 1 + 24

5x = 25

x = 25/5

x = 5

Thus;

XM = 3(5) + 1 = 16

YM = 8(5) - 24 = 16

XY = 16 + 16 = 32

2) From the given line segments, it is clear that XM is congruent to YM since M bisects XY. Thus;

XM = YM and XM + YM = XY

We are given that;

XM = 5x + 8

YM = 9x + 12

Thus;

5x + 8 = 9x + 12

9x - 5x = 8 - 12

4x = -4

x = -1

XM = 5(-1) + 8 = 3

YM = 9(-1) + 12 = 3

Common ratio= 1/2, Next two term= 1/16, 1/32

This is a geometric sequence since there is a common ratio between each term.

i.e.,

the common ratio (r) = [tex]\frac{1/2}{1}[/tex] = [tex]\frac{1/4}{1/2}[/tex]

                                  = 1/2

We can write the formula for general term of the series as

[tex]a_{n}[/tex] = a[tex](\frac{1}{2})^{n-1}[/tex]

If the further sequence does continue in the same way then the whole infinite sequence indicated is a geometric series.

So we have

[tex]a_{2}[/tex] =(1) [tex](\frac{1}{2} )^{2-1}[/tex]= 1/2

[tex]a_{3}[/tex] = 1× [tex](\frac{1}{2} )^{3-1}[/tex]= 1/4

[tex]a_{4}[/tex] = 1× [tex](\frac{1}{2} )^{4-1}[/tex]= 1/8

A cell phone tower is 173.21 feet high.

Consider the following diagram

Let AB be the height of tower, C be the position of Jen.

Jen walks 50 feet from the tower, and finds the angle of elevation from her position to the top of the tower to be 60°

An angle ACB be an angle of elevation.

⇒ ∠ACB = 60°

And AC = 50 ft

We need to find the distance AB.

Consider tangent of angle ACB.

⇒ tan(60) = AB / BC

⇒ 1.7321 = AB / 100

⇒ AB = 1.7321 × 100

⇒ AB = 173.2 feet

The total change in temperature, in degrees Fahrenheit, for the package of food is 50°F

The initial temperature of the package of food as given in the question is -15°F

At noon, the temperature of the package of food was changed to 35° F

We need to find out the total change in temperature which is

Temperature of food package at noon - The initial temperature of the package of food

By substituting the values given in question we get

                       = 35° - (-15° F)

Which is a simple integer problem

                      = 35 - (-15)

The equation of line in slope intercept form which passes through (-1, -5) and (4, -2) will be y = [tex]\frac{3}{5}[/tex] x .

What is the slope intercept form of a line ?

The equation of a straight line in the form y = mx + c is known as the slope intercept form, where m denotes the slope and c denotes the y-intercept of a line.

It is given that line is passing through (x1 , y1) and (x2 , y2) that is ,  (-1, -5) and (4, -2).

Let's find out the value of slope first.

We know that , slope (m) = (y2-y1) / (x2-x1)

⇒ m = [(-2-(-5)] / [4 - (-1)]

⇒ m = 3 / 5

Now we will use the slope to find the y-intercept.

∵ y = mx + c

where , c is the y-intercept.

(-2 -(-5)) = (3/5) × (4-(-1)) + c

3 = [ (3/5) × 5 ] + c

3 = 3 + c

c = 0

Now ; we will write the equation in slope intercept form that is ;

y = mx + c

or

y = [tex]\frac{3}{5}[/tex] × x + 0

or

y = [tex]\frac{3}{5}[/tex] x

Therefore , the equation of line in slope intercept form which passes through (-1, -5) and (4, -2) will be y = [tex]\frac{3}{5}[/tex] x .

The inequality given by (x/3) + 5 ≥ 1/6 has the solution x ≥ -29/2 or [-29/2 , +∞).

Inequality refers to the relationship between two non-equal expressions. It can be denoted by > for greater than, < for less than, >/= for greater than and equal to, and </= for less than and equal to.

To solve an inequality is to find the values of x such that when we substitute that number for x we have a true statement.

Given the inequality (x/3) + 5 ≥ 1/6, subtract 5 from both sides.

(x/3) + 5 - 5 ≥ 1/6 - 5

x/3 ≥ -29/6

Multiply both sides by 3.

3(x/3) ≥ 3(-29/6)

x ≥ -29/2

To check, let x = -29/2

x = -29/2 ≥ -29/2

Substitute this value to the inequality.

(x/3) + 5 ≥ 1/6

(-29/2)/3 + 5 ≥ 1/6

1/6 ≥ 1/6

let x = -14,

x = -14 ≥ -29/2

Substitute this value to the inequality.

(x/3) + 5 ≥ 1/6

-14/3 + 5 ≥ 1/6

1/3 ≥ 1/6

Based on the calculations below, the amount of tuition per year is $36,000 while the amount of the increase in tuition each year is $1,000.

Note: There are two questions in this question as follows:

1. How much is tuition per year?

2. By how much will tuition increase each year?

We can calculate the tuition per year and the increase in the tuition each year as below:

Number of semesters in a year = 2

Tuition in each semester = $18,000

Increase in the tuition per semester = $500

Using the above information, we can proceed as follows:

Tuition per year = Tuition in each semester * Number of semesters in a year = $18,000 = $36,000

Increase in the tuition each year =  Increase in the tuition per semester * Number of semesters in a year = $500 * 2 = $1,000

The inverse function as g⁻¹ (h)  = [(h+6)/10]² which is the correct answer would be an option (E).

The inverse function is defined as a function obtained by reversing the given function.

To determine the inverse of a function, all you have to do is switch where h and g are and resolve for g.

So after switching h and g,

g = g(h) = 10√h - 6

becomes

h = 10√g - 6

Now, we solve for h regularly.

h + 6 = 10√g

(h + 6)/10 = √g

[(h+6)/10]² ⇒ g = [(h+6)/10]² = g(x)

Therefore the inverse of g(x) is g⁻¹ (h)  = [(h+6)/10]²

Hence, the inverse function as g⁻¹ (h)  = [(h+6)/10]²

Using the normal distribution, it is found that:

b)

The maximum 39.5% obese has a z-score of 2.11, hence it is 2.11 standard deviations above the mean.

The minimum 23% obese has a z-score of -2.21, hence it is 2.21 standard deviations below the mean.

c) The interval is 23.79% to 39.07%.

The z-score of a measure X of a normally distributed variable with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex] is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

For this problem, the parameters are given as follows:

[tex]\mu = 31.43, \sigma = 3.82[/tex]

The maximum weight is of 39.5, hence:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

Z = (39.5 - 31.43)/3.82

Z = 2.11.

The maximum 39.5% obese has a z-score of 2.11, hence it is 2.11 standard deviations above the mean.

The maximum weight is of 23, hence:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

Z = (23 - 31.43)/3.82

Z = -2.21

The minimum 23% obese has a z-score of -2.21, hence it is 2.21 standard deviations below the mean.

For item c, we consider the Empirical Rule, which states that 95% of the measures are within 2 standard deviations of the mean.
