Answer:

Option D is correct.

Step-by-step explanation:

Given: Expenditure in January Month = $ 3365

Expenditure in February Month = $ 3988.50

Expenditure in March Month = $ 4010.02

Expenditure in April Month = $ 4765.87

To find: We need to find average Monthly Expenditures.

$Average=\frac{Sum\:of\:data}{total\:number\:of\:data}$

Average monthly expenditure = $\frac{3356+3988.50+4010.02+4765.87}{4}=\frac{16120.39}{4}=4030.0975$

By rounding fot to nearest hundreths, we get

Average Monthly Expenditure = 4030.10

Therefore, Option D is correct.

ii. A machine is sold for 7,000/-. The gross loss is 20% of the cost. What are the cost and gross loss?

aleksley [76]

Given:

Selling price of a machine = 7000/-

Gross loss = 20%.

To find:

The cost and gross loss.

Solution:

Let x be the cost of machine.

According to the question,

$x-20\%\text{ of }x=7000$

$x-\dfrac{20}{100}x=7000$

$x-0.2x=7000$

$0.8x=7000$

Divide both sides by 0.8.

$x=\dfrac{7000}{0.8}$

$x=8750$

So, the cost of the machine is 8750/-.

Now,

$\text{Gross Loss}=\text{Cost}-\text{Selling price}$

$\text{Gross Loss}=8750-7000$

$\text{Gross Loss}=1750$

Therefore, the gross loss is 1750/-.

What is the gradient of the blue line?? Mathswatch

yaroslaw [1]

Answer:

gradient = -5

Step-by-step explanation:

A line passes (x1, y1) and (x2, y2) has the gradient (slope) which is calculated by:

gradient = (y2-y1)/(x2-x1)

As shown in picture, this blue line passes (-1, 0) and (0, -5)

=> gradient = (-5 - 0)/(0 - -1) = -5/1 = -5

Hope this helps!
