Answer:

just keep in mind am not sure if the answer 6:15:20

Step-by-step explanation:

now we have ab= 2 : 5

               and bc= 3 : 4

so b is the common one between them so multiply both of the b together which will give u 15 so now we have b = 15

to get a multiply  2 by 3 to get 6 so a = 6

to get c multiply 4 by 5 to get 20 so c = 20

now I hope that its correct and that u understood

The value of  expression - a² - 2bc - |c| if a = -2, b = 3, and c = -3, is 11.

Mathematical expressions consist of at least two numbers or variables, at least one arithmetic operation, and a statement.

Given:

- a² - 2bc - |c|, a = -2, b = 3, and c = -3,

Plug the values of a, b, and c as shown below,

- a² - 2bc - |c|  = -(-2)² - 2 × (3) × (-3) - |-3|

- a² - 2bc - |c|  = - 4 - 6 × (-3) - 3

- a² - 2bc - |c|  = -4 + 18 - 3

- a² - 2bc - |c|  = 18 - 7

- a² - 2bc - |c|  = 11

Thus, the value of the expression is 11.

Answer:

He got a 19 out of 20, great job Edwin ;)

Step-by-step explanation:

Hope this helps :)

Edwin missed 1 question on the quiz.

The percentage is defined as a ratio expressed as a fraction of 100.

If Edwin got 95% of the questions right on a quiz and there were 20 questions in total, we can calculate the number of questions he missed by finding 5% of the total number of questions.

First, let's find 5% of 20:

= 5% of 20

= (5/100) x 20

= 1 x 20 / 100

= 20 / 100

= 0.2

Since we can't have a fraction of a question, we round the decimal up to the nearest whole number.

In this case, 0.2 rounds up to 1.

Therefore, Edwin missed 1 question on the quiz.

Answer:

Step-by-step explanation:

The proportion and percentage is as follows;

[tex]$\begin{array}{cccc}\text { Score Interval } & f & \text { Proportion } & \text { Percentage } \\ 9-10 & 29 & 0.19 & 19 \% \\ 7-8 & 53 & 0.34 & 34 \% \\ 5-6 & 50 & 0.32 & 32 \% \\ 3-4 & 22 & 0.14 & 14 \% \\ 1-2 & 1 & 0.01 & 1 \%\end{array}$[/tex]

A percentage represents a ratio or fraction with a denominator that is always 100 as opposed to a proportion, which asserts the equivalent of two ratios or fractions.

Given

[tex]$\begin{array}{cccc}\text { Score Interval } & f & \text { Proportion } & \text { Percentage } \\ 9-10 & 29 & 0.19 & 19 \% \\ 7-8 & 53 & & \\ 5-6 & 50 & & \\ 3-4 & 22 & 0.14 & 14 \% \\ 1-2 & 1 & 0.01 & 1 \%\end{array}$[/tex]

To estimate the total frequency:

Total = sum f

Total = 29 + 53 + 50 + 22 + 1

Total = 155

The proportion (p) exists calculated by:

[tex]$p = \frac{f}{\text { Total }}[/tex]

The percentage (P) exists calculated by:

P = p × 100 %

For interval 7 - 8, we have:

p = 53 / 155 = 0.34

P = 0.34 × 100 % = 34 %

For interval 5 - 6, we have:

p = 50 / 155 = 0.32

P = 0.32 × 100 % = 32 %

So, the complete table is:

[tex]$\begin{array}{cccc}\text { Score Interval } & f & \text { Proportion } & \text { Percentage } \\ 9-10 & 29 & 0.19 & 19 \% \\ 7-8 & 53 & 0.34 & 34 \% \\ 5-6 & 50 & 0.32 & 32 \% \\ 3-4 & 22 & 0.14 & 14 \% \\ 1-2 & 1 & 0.01 & 1 \%\end{array}$[/tex]

To simplify 3 ratios, divide each part of the ratio with the same amount and keep diving numbers in the ratio until they are as small as possible but they remain as whole numbers.

To simplify or reduce a fraction, first, we need to find a common factor between the ratio numbers. When we have multiple ratio numbers, we must find a common factor between all of them.

The greatest factor between all the ratio numbers (greatest common factor) will be utilised to divide or reduce the ratios down to their lowest form.

For example reduce the ratio 225: 125: 25

The first step is to determine a common factor between all of the ratio numbers. In this example, we can see that all of the numbers end in either 5 or 0. This means that each number should have 5 as a factor.

If numbers are large and we are not sure of the greatest common factor between them all, we can reduce by a common factor and then reduce again.

Now divide each number by 5 and see what we get.

225/5: 125/5: 25/5

45: 25: 5

When we divide each one by 5 again, we can see that each number again ends in 5 or 0 which means that 5 is still a factor of each number.

Now divide each number by 5 again and get a final ratio of 9: 5: 5.

45/5: 25/5: 5/5

Step-by-step explanation: To solve this equation, you'll need to use the order of operations to determine the correct sequence of steps to follow. The order of operations is a set of rules that specifies the order in which calculations should be performed in a math problem. It helps to prevent ambiguity and ensures that all calculations are performed consistently.Here is the order of operations:Perform any calculations inside parentheses or brackets first.Perform all multiplications and divisions, working from left to right.Perform all additions and subtractions, working from left to right.Using this order, we can solve the equation as follows:3.5 x 4 + 11 x 2.2 = 14 + 11 x 2.2

3.5 x 4 + 11 x 2.2 = 14 + 24.2

3.5 x 4 + 11 x 2.2 = 38.2Therefore, the solution to the equation is 38.2.

Step-by-step explanation:

In scenerio 1, the money in the retirement account at 62 years old is         $1,267,250.76

In scenerio 2, the money in the retirement account at 62 years old is         $ 633,625.38.

Scenerio 1:

a) 6% of salary = Salary * 6% = $6,100 * 6% = $366

b) Total amount the company paid monthly = 6% of salary = Salary * 6% = $6,100 * 6% = $366

c) The money in the retirement account at 62 years old can be calculated using the formula for calculating the Future Value (FV) of an Ordinary Annuity given as follows:

FV = M * (((1 + r)^n - 1) / r) ................................. (1)

Where:

FV = Future value = Money in the retirement account at 62 years old = ?

M = Monthly payment = Contribution you + Contribution by the employer = $366 + $366 = $732

r = Monthly interest rate = Annual interest rate / 12 = 6.28% / 12 = 0.0628 / 12 = 0.0052

n = number of months = Number years * Number of months in a year = (Retirement age – Age when hired) * 12 = (62 - 25) * 12 = 37 * 12 = 444

Substituting all the values into equation (1), we have:

FV = $732 * (((1 + 0.0052)^444 - 1) / 0.0052)

FV = Money in the retirement account at 62 years old = $1,267,250.76

d) Amount of money you put into the account = 6% of salary * number of months = $366 * 444 = $162,504

e) Amount of money your employer put into your account = Amount of money you put into the account = $162,504

f) Amount your account gained in interest over the years = FV – (Amount of money you put into the account + Amount of money your employer put into your account) = $1,267,250.76 – ($162,504 + $162,504) = $942,242.76

Scenario 2:

a) 3% of salary = Salary * 3% = $6,100 * 3% = $183

b) Total amount the company paid monthly = 3% of salary = Salary * 3% = $6,100 * 3% = $183

c) Using equation (1), we have:

M = Monthly payment = Contribution you + Contribution by the employer = $183 + $183 = $366

Substituting all the values into equation (1), we have:

FV = $366 * (((1 + 0.0052)^444 - 1) / 0.0052)

FV = Money in the retirement account at 62 years old = $633,625.38

d) Amount of money you put into the account = 3% of salary * number of months = $183 * 444 = $81,252.00

e) Amount of money your employer put into your account = Amount of money you put into the account = $81,252

f) Amount your account gained in interest over the years = FV – (Amount of money you put into the account + Amount of money your employer put into your account) = $633,625.38 – ($81,252 + $81,252) = $471,121.38

The difference in the amount of money at age 62 between scenarios 1 and 2 = Money in the retirement account at 62 years old in scenarios 1 + Money in the retirement account at 62 years old in scenarios 2 = $1,267,250.76 - $633,625.38 = $633,625.38

Difference in the amounts of money you put into retirement between scenarios 1 and 2 = $366 - $183 = $183

Amount got from your employer in scenario 1 than 2 = $366 - $183 = $183
