oliver drove the first 90 miles of his journey in 1.5 hours and the remaining 120 miles in 3 hours. what was the total average speed

Answers

Answer 1

90 miles + 120 miles = 210 total miles

1.5 hours + 3 hours = 4.5 total hours.

Average speed = total distance /  total time

Average speed = 210 miles / 4.5 hours = 46 2/3 miles per hour

Answer 2

The total average speed for Oliver is 42 miles per hour

Given the following data:

Distance A = 90 milesDistance B = 120 milesTime A = 1.5 hoursTime B = 3 hours

To find the total average speed:

First of all, we would determine the total distance and total speed:

[tex]Total \; distance = Distance\;A + Distance\;B\\\\Total \; distance = 90+120\\\\Total \; distance = 210\;miles[/tex]

[tex]Total \; time = Time\;A + Time\;B\\\\Total \; distance = 1.5+3\\\\Total \; distance = 4.5\;hours[/tex]

Mathematically, the average speed is given by the formula:

[tex]Average\;speed = \frac{Total\;distance}{Total\;time}[/tex]

Substituting the parameters into the formula, we have;

[tex]Average\;speed = \frac{210}{4.5}[/tex]

Average speed = 42 miles per hour.

Answers

Answer:

21.75 Miles

Step-by-step explanation:

s = d / t

d = s * t

s = 1.75 miles / 2.33333333 minutes

The midpoint of \overline{\text{AB}}
AB
is M(3, -2)M(3,−2). If the coordinates of AA are (8, 4)(8,4), what are the coordinates of BB?

Answers

Answer:

Step-by-step explanation: I am trying to interpret the question: I'll assume:

Line AB has a midpoint, M.

A is (8,4)

B is unknown, but desired

M is (3,-2)

We'll assume a straight line of the form y=mx+b, where m is the slope. m can be calculated by the "Rise" over the "Run" between the points A and M:

Rise = (4-(-2))=6

Run = (8-3)=5

Slope = (Rise/Run) = (6/5)

The line becomes y=(6/5)x+b

Calculate b, the y-intercept (the value of y when x is 0), by entering one of the two known points. I'll choose (8,4).

y=(6/5)x+b

4 = (6/5)(8)+b

b = 4 - (6/5)(8)

b = 4 - (48/5)

b = 4 - (9 3/5) or -5 3/5

The equation becomes:

y=(6/5)x - 5 3/5

Point B will have an x value of -2 [The change in x from A to M was (3-8) = -5. From M to 5 would be another -5 increment, so x goes from 3 to (3-5) or -2.

Find the value of y for x=-2:

y=(6/5)x - 5 3/5

y=(6/5)*(-2) - 5 3/5

y=(-12/5) - (28/5)

y = -(40/5) or - 8

B has coordinates of (-2, -8)

If coordinates of point A is (8, 4), then the coordinate of point B will be (-2, -8).

The "Midpoint-Formula" is used to find the coordinates of a point that lies exactly halfway between two given points. It's given as :Midpoint (M) = ((x₁ + x₂)/2, (y₁ + y₂)/2),

In this case, we have the midpoint as M(3, -2) and one of the endpoints as A(8, 4). We need to find coordinates of other endpoint which is B,

Using the midpoint formula, we rearrange it to solve for the missing coordinates (x₂, y₂),

x₂ = 2 × Mₓ - x₁,

y₂ = 2 × [tex]M_{y}[/tex] - y₁,

Substitute the given values:

We have : Mₓ = 3; [tex]M_{y}[/tex] = -2,

x₁ = 8; y₁ = 4

x₂ = 2 × 3 - 8 = -2;   y₂ = 2 × -2 - 4 = -8,

Therefore, the coordinates of point-B is(-2, -8).

17. The sum of a three-digit number
and a one-digit number is 642.
The product of the numbers is
5,072. What are the numbers?

Answers

Answer: 2  and 321 or  3  and 214

Step-by-step explanation:

One number is between 200-225.

Now, back up just a bit.  The product of the two numbers is 642.  Product comes from multiplying the two numbers.  So, if we divide 642 by the number that is between 200-225, we will get the other number.

 So, divide 200 into 642 and get 3 with a remainder of 42

     divide 225 into 642 and get 2 with a remainder of 192

This means that the other number must be either 2 or 3.  (note: this is because dividing by 200 gives the biggest value it could be and dividing by 225 gives the lowest value it could be -- think about sharing a bag of candy, dividing it between 2 friends gets each person the most candy and dividing it between more friends (3) gives each person less candy).

Well. if the other number is either 2 or 3, and the product of the two numbers is 642, the numbers must be either: 2  and 321 or  3  and 214

In a statewide lottery, one can buy a ticket for $1. With probability .0000001, one wins a million dollars ($1,000,000), and with probability .9999999 one wins nothing ($0). Let Y denote the winnings from buying one ticket. Construct the probability distribution for Y. Show that the mean of the distribution equals .10, corresponding to an expected return of 10 cents for the dollar paid.

Answers

Using the expected value, it is found that the mean of the distribution equals $0.1.

The expected value, which is the mean of the distribution, is given by each outcome multiplied by it's probability.

The probabilities of each outcome are:

.0000001 probability of earning $1,000,000..9999999 probability of earning $0.

Thus, the mean is given by:

[tex]E(Y) = 0.0000001(1000000) + 0.9999999(0) = 0.1[/tex]

Thus showing that the expected value is $0.1.

Answer:

Step-by-step explanation:

Let the first test score is x, then the next two are x - 10 and x - 20 and the total of three is 258.

We can reflect this as:

x + x - 10 + x - 20 = 258

Solving we get:

3x - 30 = 2583x = 258 + 303x = 288x = 288/3x = 96

The scores are: 96, 86 and 76
