The board that makes the question complete is attached with this answer.

Answer:

The probability that you do not get 10 points is 0.913 (To the nearest thousandths).

Step-by-step explanation:

Given that your dart is equally likely to hit any point inside the square board, we are required to find the probability that you do not get 10 points.

This can be obtained by first obtaining the probability of you getting 10 points, and then subtracting it from 1.

The Probability of Success plus The Probability of Failure of an event is always equal to 1.

Let p be the probability of success, and q be the probability of failure. Then

p + q = 1

=> p = 1 - q

And q = 1 - p

From the attached image, we need to find the area of the entire board, and the area of the circle that contains 10.

Area of entire board = 18² = 324

Area of the circle containing 10 = πr² = π(3²) = 9π

Where r is the radius, 3in.

Probability of hitting 10, P(10) = 9π/324

= 0.08727

≈ 0.087 (to the nearest thousandths)

Now, the probability of not hitting 10

= 1 minus probability of hitting 10.

= 1 - 0.087

= 0.913

Aaron’s mother purchases a new computer for $1750. If she claims a linear depreciation (loss of value) on the computer at a rate
kirill [66]

After 8 years the value of the computer to be $0 if the Aaron’s mother purchases a new computer for $1750.

<h3>What is a sequence?</h3>

It is defined as the systematic way of representing the data that follows a certain rule of arithmetic.

We have:

Aaron’s mother purchases a new computer for $1750. If she claims a linear depreciation (loss of value) on the computer at a rate of $250 per year.

The above problem can be solved using concept of arithmetic sequence

The starting value = $1750

After one year = 1750 - 250 = $1500

After second year = 1500 - 250 = $1250

Common difference = 1500 - 1750 = -250

a(n) = 1750 + (n - 1)(-250)

a(n) = 0  (final value is zero given)

0 = 1750 + (n - 1)(-250)

n - 1 = 7

n = 8 years

Thus, after 8 years the value of the computer to be $0 if the Aaron’s mother purchases a new computer for $1750.

Factor this trinomial completely.
zmey [24]
First you want to write 7x as a sum or difference: 15x-8x
Now, the expression would look like this: 10x^2+15x-8x-12
Next, factor out the 5x and -4 from the expression: 5x(2x+3)-4(2x+3)
Now, factor out the 2x+3 from the expression and you have your answer:
(2x+3)(5x-4)

Family traveled 25 miles in 1/2 hour. If it’s currently 3:00 pm and the destination is 225 miles away, what time will they arriv
dangina [55]

It is currently 03:00 PM, the family will reach at 03:00+4.5 = 07:30 PM

Step-by-step explanation:

We have to calculate the speed first to find the time it will take the family to complete the trip.

Given

Distance = d = 25 miles

Time = t = 1/2 hours = 0.5 hours

Speed =\frac{d}{t}\\=\frac{25}{0.5}\\=50 miles\ per\ hour

Now,

Distance remaining = 225 miles

Speed = 50 miles per hour

s=\frac{d}{t}\\t=\frac{d}{s}\\t=\frac{225}{50}\\t=4.5\ hours

As we see that the time required to complete the journey is 4.5 hours.

It is currently 03:00 PM, the family will reach at 03:00+4.5 = 07:30 PM
