A car owner buys diesel at rs 7.50, rs 8, rs 8.50 per litre for three successive years. what approximately is the average cost p
alex41 [277]

Answer:

Average cost per litre of diesel = rs 8.00

Step-by-step explanation:

Amount spent on diesel each year = rs 4000

Price of a litre of diesel in the first year = rs 7.50

Price of a litre of diesel in the second year = rs 8.00

Price of a litre of diesel in the third year = rs 8.50

Average cost per litre of diesel = \frac{p_{1} + p_{2} + p_{3}  }{n}

where n is the number of years.

Average cost per litre of diesel  =  \frac{7.5 + 8.00 + 8.50}{3}

                                                     = \frac{24}{3}

                                                     = 8

Average cost per litre of diesel is rs 8.00

So that he buys an average of 500 (i.e \frac{4000}{8}) litres every year.

In a particular game, a fair die is tossed. If the number of spots showing is either four or five, you win $1. If the number of
TiliK225 [7]

Answer:

The probability that you win at least $1 both times is 0.25 = 25%.

Step-by-step explanation:

For each game, there are only two possible outcomes. Either you win at least $1, or you do not. Games are independent. This means that the binomial probability distribution is used to solve this question.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}

In which C_{n,x} is the number of different combinations of x objects from a set of n elements, given by the following formula.

C_{n,x} = \frac{n!}{x!(n-x)!}

And p is the probability of X happening.

Probability of winning at least $1 on a single game:

The die has 6 sides.

If it lands on 4, 5 or 6(either of the three sides), you win at least $1. So

p = \frac{1}{2} = 0.5

You are going to play the game twice.

This means that n = 2

The probability that you win at least $1 both times is

This is P(X = 2).

P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}

P(X = 2) = C_{2,2}.(0.5)^{2}.(0.5)^{2} = 0.25

The probability that you win at least $1 both times is 0.25 = 25%.

What’s the slope and y - intercept of this equation ?
zavuch27 [327]

Answer:

Slope = -\frac{7}{3}

Y-intercept = 4

Step-by-step explanation:

-> See attached

-> This equation is in slope-intercept form.

         [] When we use y = mx + b, the m is the slope and the b is our y-intercept.

Have a nice day!

     I hope this is what you are looking for, but if not - comment! I will edit and update my answer accordingly.
