Answer:

To calculate 2 3/4 of 500 grams, follow these steps:

1. Convert the mixed number to an improper fraction:

2 3/4 = (2 x 4 + 3)/4 = 11/4

2. Multiply the improper fraction by 500:

11/4 x 500 = (11 x 500)/4 = 2,750/4

3. Simplify the fraction by dividing the numerator and denominator by their greatest common factor, which is 2:

2,750/4 = (2 x 1,375)/(2 x 2) = 1,375/2

Therefore, 2 3/4 of 500 grams is equal to 1,375/2 grams or 687.5 grams.

Kevin has $3840 invested in stocks in total.

percentage, a relative value indicating hundredth parts of any quantity.

Given that Annual interest in first investment - 11%

Annual interest in other investment - 14%

Total interest annually - $480

Let us assume, x is the investment in each stock

or, total investment = 2x

then, making an equation for the total interest

0.11x+.14x=480

Multiplying everything by 100

11x+14x=48000

25x=48000

Divide both sides by 25

x=1920

then, by total investment = 2x

2×(1920) = 3840

Hence, Kevin has $3840 invested in stocks in total.

The equivalent expression of 2b + 4 is 2(b + 2) .

Equivalent expressions are expressions that work the same even though

they look different.

In other words, two expressions are said to be equivalent if they have the

same value irrespective of the value of the variable(s) in them.

If two algebraic expressions are equivalent, then the two expressions

have the same value when we plug in the same value for the variable.

Therefore, let's find the equivalent expression of 2b + 4.

Hence, using common factor,

2b + 4 = 2(b + 2)

Therefore, the equivalent of 2b + 4  is 2(b + 2)

The capacity of the mug is 1.2. The capacity of the mug can be found by using the equation C = (3/4) ÷ (5/8).

It is the maximum amount of output that can be produced in a given period of time. Capacity is usually expressed in terms of units per unit of time, such as gallons per minute or passengers per hour.

In this equation, 3/4 represents the amount of water in the mug, and 5/8 represents the amount the mug is full.

Let the capacity of the mug be x.

Given,

Mug is 5/8 full and contains 3/4 of water

So, 5/8 of the mug is filled with water

Therefore,

5/8 of x = 3/4

(5/8 )x = (3/4)

x = (3/4) × (8/5)

x = (24/20)

x = 1.2

Therefore, the capacity of the mug is 1.2.

The equation that represents a quadratic relationship is y = 4x^2. Option A.

A quadratic relationship is a mathematical relationship where the variable y is a function of the variable x raised to the power of 2. In other words, it is an equation in which the highest power of the variable is 2.

Let's analyze the given equations:

1. y = 4x^2: This equation represents a quadratic relationship because the variable x is raised to the power of 2. The term 4x^2 indicates that the relationship between x and y is quadratic.

2. y = 4x^4: This equation represents a quartic relationship, not a quadratic relationship. The variable x is raised to the power of 4, which indicates a higher degree relationship than quadratic.

3. y = 4x^3: This equation represents a cubic relationship, not a quadratic relationship. The variable x is raised to the power of 3, indicating a higher degree relationship.

4. y = 4: This equation represents a linear relationship, not a quadratic relationship. It is a constant equation where y is always equal to 4, regardless of the value of x. In a quadratic relationship, the variable x should have a power of 2. Option A.

Answer:

y = 3x +1 (1)

2y = 6x +2  (2)

We can devide equation (2) by 2 and we got:

\( y =3x +1\)   (3)

And since equations (1) and (3) are equal we can do this:

\( 3x +1 = 3x+1\)

And that implies:

Answer:

f(5) = 35

Step-by-step explanation:

In any function f(x), x is the input and f(x) is the output

Example:

f(x) = 2x + 3, find f(a)

That means we need to find value of f(x) at x = a, so substitute x by a

f(a) = 2(a) + 3 = 2a + 3

f(a) = 2a + 3

Let us use the same way to solve our question

∵ f(x) = x² + 2x

→ We need to find f(5), so substitute x by 5

∴ f(5) = (5)² + 2(5)

∴ f(5) = 25 + 10

→ Do addition

∴ f(5) = 35

Answer:

The mean absolute deviation (MAD) of the dataset is 33.333.

Step-by-step explanation:

The mean absolute deviation (MAD) of a dataset is the average distance between each data point and the mean. It gives us an idea about the variability in a dataset.

These are the steps to calculate the mean absolute deviation.

Step 1: Calculate the mean.

\(Mean = \frac{20+90+25+100+85+30}{6} =\frac{175}{3}\approx58.333\)

Step 2: Calculate how far away each data point is from the mean using positive distances. These are called absolute deviations.

\(|20-\frac{175}{3} |=\frac{115}{3}\\\\|90-\frac{175}{3} |=\frac{95}{3}\\\\|25-\frac{175}{3} |=\frac{100}{3}\\\\|100-\frac{175}{3} |=\frac{125}{3}\\\\|85-\frac{175}{3} |=\frac{80}{3}\\\\|30-\frac{175}{3} |=\frac{85}{3}\)

Step 3: Add those deviations together.

\(\frac{115}{3}+\frac{95}{3}+\frac{100}{3}+\frac{125}{3}+\frac{80}{3}+\frac{85}{3}=\frac{600}{3}=200\)

Step 4: Divide the sum by the number of data points.

\(MAD=\frac{200}{6} =33.333\)

Answer:

There was a 45% increase in furniture sales.

Furniture sales rose by 9 percentage points.

Step-by-step explanation:

absolute difference = new - old

29-20= 9 percentage points

absolute difference / initial value = 9/20 = .45 * 100 = 45%

Two statements which are true about furniture sales are  \((a)\) There was a \(45\%\) increase in furniture sales and  \((f)\)  Furniture sales rose by \(9\) percentage points.

Percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, "%".

Percentage \(=\frac{Obtained\ number}{Total\ number}\ * 100\)

We have,

Sales of furniture in \(2015=20\%\)

Sales of furniture in \(2016=29\%\),

So,

Change in Percentage \(=29-20=9\%\)

i.e.

Sales rise by \(9\%\) points,

And,

Increase in Percentage \(=\frac{9}{20}\ *100=45\%\)

Hence, we can say that Two statements which are true about furniture sales are \((a)\) There was a \(45\%\) increase in furniture sales and \((f)\) Furniture sales rose by \(9\) percentage points.
