The amount Rebecca has put into fixed savings each month to cover her annual expenses for life insurance, auto insurance and real estate taxes is $ 194.

Given that:-

Amount invested in life insurance = $ 255

Number of payments in life insurance = 4

Amount invested in real estate taxes = $ 455.35

Number of payments in real estate taxes  = 2

Amount invested in auto insurance = $ 66.21

Number of payments in auto insurance = 6

We have to find the amount Rebecca has put into fixed savings each month to cover her annual expenses for life insurance, auto insurance and real estate taxes.

Hence,

Total amount put by Rebecca in a year = 255*4 + 455.35*2 + 66.21*6 = 1020 + 910.70 + 397.26 = $ 2,327.96

Amount put by Rebecca in a month = 2327.96/12 =  $ 193.997 ≈ $ 194

The amount of money that Johnny makes now = $282,508.38

Annual payment is the type of payment that is done every 12 month and by the end of the year.

The initial annual payment received by Johnny= $111,180

The new career pays the rate of 154.1% more that is;

( 154.2% of $111,180 ) + $111,180 Which is;

= (154.1/100 × 111,180) + $111,180

McKenzie wants to determine which ice cream option is the best choice.

Part (a)

Volume of Scoop:

A scoop of ice cream is considered a perfect sphere and has a 2-inch diameter.

The volume of the sphere is given by

Where r is the radius.

We know that radius is half of the diameter.

So, the volume of a scoop of ice cream is

Therefore, the volume of a scoop of ice cream is 4.19 in³

Volume of Cone:

A cone has a 2-inch diameter and a height of 4.5 inches.

The volume of a cone is given by

Where r is the radius and h is the height of the cone.

We know that radius is half of the diameter.

So, the volume of a cone of ice cream is

Therefore, the volume of a cone of ice cream is 4.71 in³

Volume of Cup:

A cup, considered a right circular cylinder, has a 3-inch diameter and a height of 2 inches.

The volume of a right circular cylinder is given by

Where r is the radius and h is the height of the right circular cylinder.

We know that radius is half of the diameter.

So, the volume of a cup of ice cream is

Therefore, the volume of a cup of ice cream is 14.13 in³

Part (b)

Now let us compare the various given options and decide which option is the best value for money

Option 1:

The price of one scoop in a cup is $2

The volume of one scoop of ice cream is 4.19 in³

Option 2:

The price of two scoops in a cup is $3

The volume of one scoop of ice cream is 4.19 in³

Option 3:

The price of three scoops in a cup is $4

The volume of one scoop of ice cream is 4.19 in³

Option 4:

The price of half a scoop in a cone is $2

The volume of one scoop of ice cream is 4.19 in³

The volume of one cone of ice cream is 4.71 in³

Option 5:

The price of a cup filled with ice cream is $4

The volume of a cup is 14.13 in³

As you can see, the option 5 (a cup filled with ice cream) has the highest rate (volume/$)

This means that option 5 provides the best value for money.

Therefore, McKenzie should choose "a cup filled with ice cream level to the top of cup" for the best value for money.

where x is the number of days since the start of the job

and f(x) is the rate of change

Step 1

a)find the total expenditure if the job takes 12 days

so, as x represents the number of days, just replace and calculate

let x= 12

so

a) 51.1

Step 2

now, let's find the total spent on the job from the 10 to 20th day

a) find the x value ( number of days since the job started)

x= 20 days-10dys= 10

so

The correct option is negative 23 over 14 times j plus negative 1 over 15

Given,

The expression negative one seventh j plus two fifths minus the expression three halves j plus seven fifteenths

The expression; -1/7j + 2/5 - 3/2j + 7/15

negative one seventh j = - 1/7j

two fifths = 2/5

three halves j = 3/2 j

seven fifteenths = 7/15

Now,

Substitute the values;

- 1/7j + 2/5 - 3/2j - 7/15

Answer:

-8, -5, -2, 1, 4

Explanation:

The given sequence is an arithmetic sequence -8, -5, -2 ....

The nth term of the sequence is expressed as;

Tn = a+ (n-1)d

a is the first term = -8

d is the common difference = -5 -(-8) = -2-(-5)

d = -5+8 = -2+5 = 3

Get the 4th term;

n = 4

T4 = -8+(4-1)*(3)

T4 = -8+3(3)

T4 = -8+9

T4 = 1

Get the 5th term:

n = 5

T5 = -8 + (5-1)*3

T5 = -8+4(3)

T5 = -8 + 12

T5 = 4

Hence the next two terms of the sequence are 1 and 4

A 90% confidence interval for the proportion of cell phone owners aged 18 - 24 who have an Android phone is

..............< p <...............

We have to construct the 90% confidence interval.

From the given question we know that among 240 cell phone owners aged 18 - 24 surveyed, 108 said their phone was an android phone.

So the total number of cell phone owners aged 18 - 24 is 240.

So n=240

From them 108 have an android phone.

So x=108

Estimation of sample proportion([tex]\hat p[/tex]) = x/n

Now putting the value

Estimation of sample proportion([tex]\hat p[/tex]) = 108/240

Estimation of sample proportion([tex]\hat p[/tex]) = 0.45

Now the construct a 90% confidence interval for the proportion of cell phone owners aged 18 - 24 who have an Android phone

C.I. = [tex](\hat p \pm z_{\alpha /2}\sqrt\frac{\hat p(1-\hat p)}{n}})[/tex]

As we know that

[tex]\hat p=0.45[/tex]

Now finding the value of [tex]z_{\alpha /2}[/tex]

We have to find the 90% confidence interval. We can write 90% as 90/100 = 0.90

So [tex]\alpha[/tex] = 1-0.90

So [tex]z_{\alpha /2}=z_{0.10 /2}[/tex]

[tex]z_{\alpha /2}=z_{0.05}[/tex]

From the standard z table

[tex]z_{0.05}[/tex] = 1.645

Now putting the value in the

C.I. =  [tex](\hat p \pm z_{\alpha /2}\sqrt\frac{\hat p(1-\hat p)}{n}})[/tex]

C.I. = [tex](0.45 \pm 1.645{\sqrt\frac{0.45(1-0.45)}{240}})[/tex]

Simplifying

C.I. = [tex](0.45 \pm 1.645{\sqrt\frac{0.45\times0.55}{240}})[/tex]

C.I. = [tex](0.45 \pm 1.645{\sqrt\frac{0.2475}{240}})[/tex]

C.I. = [tex](0.45 \pm 1.645\sqrt{0.001031})[/tex]

C.I. = [tex](0.45 \pm 1.645\times0.0321)[/tex]

C.I. = [tex](0.45 \pm 0.053)[/tex]

We can write it as

C.I. = {(0.45+0.053),(0.45-0.053)}

C.I. = (0.503,0.397)

Hence, a 90% confidence interval for the proportion of cell phone owners aged 18 - 24 who have an Android phone is

The length of BC is 29 units (solved using trigonometry and its applications).

What is trigonometry?

Trigonometry (from Ancient Greek v (trgnon) 'triangle' and (métron)'measure') is a field of mathematics that explores the correlations between triangle side lengths and angles. The topic arose in the Hellenistic civilization during the third century BC from geometric applications to astronomical research. The Greeks concentrated on chord computation, whereas Indian mathematicians established the first-known tables of values for trigonometric ratios (also known as trigonometric functions) such as sine. Trigonometry has been used throughout history in geodesy, surveying, celestial mechanics, and navigation. Trigonometry is well-known for its many identities. These trigonometric identities are frequently used to rewrite trigonometrical expressions with the goal of simplifying an expression, finding a more usable form of an expression, or solving an equation.

Let the point where AB is cut through line from C be D

This can be solved using trigonometry and its applications.

In triangle ACD,

tan 45° = CD/AD

or, CD = tan 45° x AD

           = 1 x 20

            = 20 units

In triangle CDB,

tan Ф = CD/BD

or, Ф = tan⁻¹(CD/BD)

         = tan⁻¹(20/21)

         = 43.6°

so, sin 43.6° = CD/BC

or, BC = CD/sin 43.6°

           = 20/0.689

           = 29 units

The length of BC is 29 units.

The core concept of mathematics' calculus is functions. The unique varieties of relations are the functions. In mathematics, a function is represented as a rule that produces a distinct result for each input x. In mathematics, a function is indicated by a mapping or transformation. Typically, these functions are identified by letters like f, g, and h. The collection of all the values that the function may input while it is defined is known as the domain. The entire set of values that the function's output can produce is referred to as the range. The set of values that could be a function's outputs is known as the co-domain.

Given:

g(n) = n² − 4, h(n) = n − 5

g(n).h(n)

= (n² − 4).(n-5)

= n³ - 5n² - 4n + 20
