PLEASE HELP ME!<br><br> Expand the polynomial:<br><br> (b–c)(b^2–bc

How do I solve this equation?

kow [346]

Answer: 2 * sqrt(2)

I attached an image to show you what I mean

Step-by-step explanation:

First add 20 on both sides

5x^(2 / 3) = 10

divide both sides by 5

x^(2 / 3) = 2

Now be reminded that the power of 2/3 is the same as x^2 cube root (to the third root)

So we now cube both sides to get rid of the cube root

x^2 = 2^3

which simplifies to x^2 = 8

We now just find the square root of both sides

so x = sqrt(8)

square root of 8 is simply sqrt(4 * 2) = sqrt(4) * sqrt(2) = 2 * sqrt(2)

So x = 2 * sqrt (2)

1. Which property is illustrated by the statement?(statement below)

bearhunter [10]

1. 8(-5/6) = (-5/6)8 illustrates the commutative property of multiplication.

2. 5.4 + 3 = 3 + 5.4 illustrates the commutative property of addition.

<h3>What is the Commutative Property of Multiplication?</h3>

The commutative property of multiplication states that the arrangement of change of numbers that you want to multiply does not change what you would get as the product.

For example, a × b = b × a.

In the same vein, 8(-5/6) = (-5/6)8 illustrates the commutative property of multiplication.

<h3>What is the Commutative Property of Addition?</h3>

The commutative property of addition also states that the order or arrangement of addends will not change the sum you would get.

For example, 3 + 2 = 2 + 3.

Therefore, the statement, 5.4 + 3 = 3 + 5.4 illustrates the commutative property of addition.

The monthly worldwide average number of airplane crashes of commercial airlines is 3.5. What is the probabil- ity that there wil

Levart [38]

Answer:

Step-by-step explanation:

We would apply the formula for poisson distribution which is expressed as

P(x = r) = (e^- µ × µ^r)/r!

Where

µ represents the mean of the theoretical distribution.

r represents the number of successes of the event.

From the information given,

µ = 3.5

a)

For the probability that there will be at least 2 such accidents in the next month, it is expressed as

P(x ≥ 2) = 1 - P(x < 2)

P(x < 2) = P(x = 0) + P(x = 1)

Therefore,

P(x = 0) = (e^- 3.5 × 3.5^0)/0!

P(x = 0) = (e^- 3.5 × 1)/1

P(x = 0) = 0.03

P(x = 1) = (e^- 3.5 × 3.5^1)/1!

P(x = 1) = (e^- 3.5 × 3.5)/1

P(x = 1) = 0.11

P(x < 2) = P(x = 0) + P(x = 1) = 0.03 + 0.11 = 0.14

P(x ≥ 2) = 1 - 0.14 = 0.86

b)

For the probability that there will be at most 1 accident in the next month, it is expressed as

P(x ≤ 1) = P(x = 0) + P(x = 1)

P(x = 0) = 0.03

P(x = 1) = 0.11

P(x ≤ 1) = 0.03 + 0.11 = 0.14

Lin runs 5 laps around a track in 6 minutes.

Paladinen [302]

Answer:

25.2

Step-by-step explanation:

6/5 is 1.2, so it takes 1.2 minutes to run one lap.

This means 21 x 1.2 = the minutes it takes to run 21 laps around the track.

Therefore it takes 25.2 minutes to run around the track 21 times.
