Answer:

<h2>Bob has 16.67% of winning the game at his first roll.</h2>

Step-by-step explanation:

According to the problem, they are playing with a simple dice, which means it has 6 possible outcomes 1, 2, 3, 4, 5 and 6.

The one that gets 6 wins.

To find the probability of winning the first Bob's roll, we just need to find the simple probability of getting 6, which is

P=\frac{1}{6}

Therefore, Bob has 16.67% of winning the game at his first roll.

lbvjy [14]

Answer:

"the original amount of the loan"

Step-by-step explanation:

x value would be the time in months and y value would be the loan amount that is left.

The y-intercept is basically the point where x is 0. So, we can say the y-intercept would be when time is 0.

<em>That's basically when the loan started and the y-value represents the full loan amount., which is $22,000.</em>

<em />

The correct answer is third option -- "the original amount of the loan".

Kamila buys a dress for £30 in a sale. It was advertised "25%off". Kamila says"25% of £30 is £7.50 so i saved £7.50". Explain wh
sveta [45]

Answer:

She was wrong in her analysis because the sales discount of 25% is the discount on the original cost of the dress and not the purchasing cost of the dress as explained below:

Step-by-step explanation:

From the question:

Purchasing cost price of the dress = £30

However, this cost (£30) was after a 25% Sales Discount        

It, therefore, implies that £30 is equal to 75% of the cost price

75% of the original cost price  = £30

100% of the original cost price = (30 x100%)/75%

   Original cost price                 = £40

Therefore the 25% discount / savings on the cost

                                                     = £ (40-30)

                                                      = £10    

She saved £10 by buying the dress at £30 instead of the original cost of £40

Y = 3 - 5x <br><br><br> solve for x
boyakko [2]

Answer:

x = -1/5y + 3/5

Step-by-step explanation:

y = 3 - 5x

Subtract 3 from both sides;

y - 3 = -5x

Divide both sides by -5

-1/5y + 3/5 = x

Find a linear equation to model this real-world application:
SSSSS [86.1K]

The linear equation to model the company's monthly expenses is y = 2.5x + 3650

<em><u>Solution:</u></em>

Let "x" be the units produced in a month

It costs ABC electronics company $2.50 per unit to produce a part used in a popular brand of desktop computers.

Cost per unit = $ 2.50

The company has monthly operating expenses of $350 for utilities and $3300 for salaries

We have to write the linear equation

The linear equation to model the company's monthly expenses in the form of:

y = mx + b

Cost per unit = $ 2.50

Monthly Expenses = $ 350 for utilities and $ 3300 for salaries

Let "y" be the total monthly expenses per month

Then,

Total expenses = Cost per unit(number of units) + Monthly Expenses

y = 2.50(x) + 350 + 3300\\\\y = 2.5x + 3650

Thus the linear equation to model the company's monthly expenses is y = 2.5x + 3650
