John sold wrapping paper for a school fundraiser. He earned 10 points for every roll he sold. He earned a total of 460 points. Write and solve an equation to determine the number of rolls of wrapping paper John sold.

Answer:

16.5

Step-by-step explanation:

Find the value represented by a z-score of 2.403, given µ=63 and σ=4.25. Round your answer to one decimal place.

The z score formula =

z = (x-μ)/σ, where

x is the raw score = ?

μ is the population mean = 63

σ is the population standard deviation = 4.25

z = 2.403

Hence,

2.403 = (x - 63)/4.25

Cross Multiply

2.403 × 4.25 = x - 6.3

10.21275 = x - 6.3

Collect like terms

10.21275 + 6.3 = x

x = 16.51275

Approximately to 1 decimal place the value = 16.5

Answer:

FV= $70,887.15

Step-by-step explanation:

First, we need to calculate the future value of the $130 deposit for 5 years:

FV= {A*[(1+i)^n-1]}/i

A= monthly deposit= $130

i= 0.08/12= 0.0067

n= 5*12= 60 months

FV= {130*[(1.0067^60) - 1]} / 0.0067

FV= $9,561.96

Now, using the following formula, the future value of the investment after 25 years:

FV= PV*(1 + i)^n

n= 25*12= 300

FV= 9,561.96*(1.0067^300)

FV= $70,887.15

Answer:

Speed = 7520 km/h

Step-by-step explanation:

Given the following data;

Distance = 22,200,000 km.

Time = 1230 Earth days

To find the average speed of the planet;

First of all, we would have to convert the time in Earth days to hours;

1 Earth day = 24 hours

1230 Earth day = x

Cross-multiplying, we have;

x = 1230 * 24

x = 29520 hours

Therefore, time = 29520 hours

Substituting into the formula, we have;

Speed = 22200000/29520

Speed = 7520.325 km/h

To 3 significant figures;

Speed = 7520 km/h

Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

Number of candles =(total volumes used by the company)/(volume of one candle)

Volume of one candle =5cm x 2cm x 12cm=120cm^3

Number of candles =5040/120

N = 42 candles

Therefore, the number of candles will be 42.

Answer:

Zeroes are x = 6 and x = -4

Factored form is - ( x + 4 ) ( x - 6 )

Standard form is -x^2 + 2x +24

Step-by-step explanation:

Solve out the equation to get the standard form, then factor that equation to get the factored form. Set each factor equal to zero and solve for x to get zeroes of the function

Answer:

(a) Next number is 8

(c) Next alphabet is M

Step-by-step explanation:

Given

[tex](a)\ 2, 4, 6[/tex]

[tex](c)\ A, D, G, J[/tex]

Solving (a): The next number

In the given sequence, each item is gotten by adding 2 to the previous item.

i.e.

[tex]4 \to 2 + 2[/tex]

[tex]6 \to 4 + 2[/tex]

So, the rule is: Add 2

Hence, the next number is:

[tex]Next = 6 + 2[/tex]

[tex]Next = 8[/tex]

Solving (c): The next letter

In the given sequence, each letter is gotten by skipping two alphabets i.e.

[tex]D \to A []\ [] D[/tex]

[tex]G \to D []\ [] G[/tex]

[tex]J \to G []\ [] J[/tex]

So, the rule is: skip 2 alphabets

[tex]Next: J \ []\ [] M[/tex]

The next letter is M

Solving (b); The next figure

This question requires an attachment.

Since, none is given; I will give a general explanation.

First, you need to study the pattern, identify the rule, then apply the rule

Take for instance, the attached image.

The pattern follows that:

1 layer, 3 dots

2 layers, 6 dots

3 layers, 9 dots

4 layers, 12 dots

This implies that,

Rule: Add 1 layer and 3 dots

So, the next will be:

5 layers, 15 dots

Answer:

11.30 g/in^3

Step-by-step explanation:

Given data

Dimensions of a rectangular prism

5.2 in by 4.5 in by 6.0 in

Hence the volume is given as

Volume= 5.2*4.5*6.0

Volume= 140.4in^3

Weight=  1587 grams

We know that density is

Density= mass/volume

Density=  1587 / 140.4

Density= 11.30 g/in^3

It would take 22.7 years for the value of the account to reach $7,700.

An equation contains one or more terms with variables connected by an equal sign.

Example:

2x + 4y = 9 is an equation.

2x = 8 is an equation.

We have,

Since the money in the account is doubling every 15 years.

The following equation is used to find the time it takes to reach a certain value:

t = (ln(P/F))/(ln(1+r))

where:

P = the initial investment amount

F = the future value we want to reach

r = the growth rate per period

ln = natural logarithm

t = the number of years it takes to reach F

P = $3,500

F = $7,700

r = ln(2)/15 (since the money is doubling every 15 years).

Plugging these values into the equation.

t = (ln(3500/7700)) / (ln(1+ln(2)/15))

t = ln (5/11) / ln (1 + 0.30/15)

t = 22.7

Therefore,

It would take 22.7 years for the value of the account to reach $7,700.

The probability that a randomly selected resident of the Gold dorm is a senior is 0.1562

Step-by-step explanation:

The given percentage of each class of student is presented as follows;

Priority A (seniors) = 22%, ∴ P(s) = 0.22

Priority B (juniors) = 29%, ∴ P(j) = 0.29

Priority C (freshmen and sophomores) = (100 - 22 - 29)% = 49%, ∴ P(fs) = 0.49

The percentage of the seniors that elect to live at the Gold dorm, = 71%, ∴ P(sG) = 0.71

The percentage of the juniors that live at the Gold dorm = 19%, ∴ P(jG) = 0.19

The percentage of the freshmen and sophomores that live in the Gold dorm = 5%, ∴ P(fsG) = 0.05

The probability that a randomly selected resident of the Gold dorm is a senior = P(s∩sG) = P(s) × P(sG)

∴ P(s∩sG) = 0.22 × 0.71 = 0.1562

Therefore;

The probability that a randomly selected resident of the Gold dorm is a senior = P(s∩sG) = 0.1562.
