Brooke bought 5 plates for $44. If the price of the plates is always the same, which represents the total cost, y, of buying any number of plates, x?

Answers

Answer:

y = 8.80x

Step-by-step explanation:

Th price of one plate = $44 / 5 = $8.80

the cost of any x plate can be determined by multiplying $8.80 by x

y = $8.80x

For example if x is 10, y =  $8.80(10) = $88

If x = 100, y = $8.80(100) = $880

Answer:

y = 8.80x

Step-by-step explanation:

Th price of one plate = $44 / 5 = $8.80

the cost of any x plate can be determined by multiplying $8.80 by x

y = $8.80x

For example if x is 10, y =  $8.80(10) = $88

If x = 100, y = $8.80(100) = $880

The velocity, v(t), of a particle, in inches per second, at time t seconds is v(t) = 4t3 + 3t2 + 2t + 1. What distance does the particle travel over the interval 0 ≤ t ≤ 1?

Answers

Answer:

The particle traveled 4 inches over the interval.

Step-by-step explanation:

What distance does the particle travel over the interval 0 ≤ t ≤ 1?

The distance is the integral of the velocity.

So

[tex]d(t) = \int_{0}^{1} v(t) dt[/tex]

[tex]d(t) = \int_{0}^{1} 4t^3 + 3t^2 + 2t + 1 dt[/tex]

We have that:

[tex]\int t^n dn = \frac{t^{n+1}}{n+1}[/tex]

So

[tex]d(t) = t^4 + t^3 + t^2 + t|_{0}^{1}[/tex]

Which is:

[tex]d(1) - d(0) = 1 + 1 + 1 + 1 = 4[/tex]

The particle traveled 4 inches over the interval.

Justin took a quiz with five multiple choice (A-D) and five true/false questions. How many different ways can he answer the questions?

Answers

Answer:

32,768 ways

Step-by-step explanation:

True/ false questions = 5 ; number of options = 2 (True or false)

Ways of answering = 2^5 = (2 * 2 * 2 * 2 * 2) = 32

Number of Multiple choice questions = 5

Number of options (A - D) = 4 options

Ways of answering = 4^5 = (4 * 4 * 4 * 4 * 4) = 1024

32 * 1024 = 32,768 ways

Frequency 3,6,8,11,14,16,15,12,9,5,1

Answers

The experimental probability of rolling a 7 would be 4/25 (16%). Experimental probably is found by putting the frequency of the event over the total number of trials. In this case that is 16/100, which reduces to 4/25.
