Option (3)

Step-by-step explanation:

Given expression is,

(6 × 10⁸) ÷ (1.5 × 10⁻⁴)

We can rewrite the given expression as,

[tex]\frac{6\times 10^8}{1.5\times 10^{-4}}[/tex]

Now by solving this expression further,

[tex]\frac{6\times 10^8}{1.5\times 10^{-4}}=\frac{6}{1.5}\times \frac{10^8}{10^{-4}}[/tex]

             [tex]=4\times 10^8\times 10^4[/tex] [Since [tex]\frac{1}{10^{-4}} =10^4[/tex]]

             = [tex]4\times 10^{(8+4)}[/tex]

             = [tex]4\times 10^{12}[/tex]

Therefore, Quotient of the given expression is [tex]4\times 10^{12}[/tex].

Option (3) will be the answer.

Answer:

[tex]x=\frac{23}{6}[/tex] or [tex]4.6[/tex]

Step-by-step explanation:

[tex]3x + 2x + 7 = 10x - 16[/tex]

[tex]5x+7=10x-16[/tex]

Subtract 7 from both sides:

[tex]5x+7-7=10x-16-7\\5x=10x-23[/tex]

Subtract 10x from both sides:

[tex]5x-10x=10x-23-10x\\-5x=-23[/tex]

Divide both sides by -5:

[tex]\frac{-5x}{-5}=\frac{-23}{-5}\\x=\frac{23}{5}[/tex] or [tex]4.6[/tex]

Answer:

Joni.

Step-by-step explanation:

Joni's calculation is the closest to the actual value.

How much Wally was off: [tex]12.8-12.546=0.254[/tex]

How much Rex was off: [tex]12.8-12.59=0.21[/tex]

How much Amanda was off: [tex]12.8-12.69=0.11[/tex]

How much Joni was off: [tex]12.8-12.75=0.05[/tex]

She was off by 0.05, which is the smallest out of the other people.

This means that her calculation was the closest to the actual value of 12.8 oz.

Thus, her calculation is the most accurate.

Answer:

The vector of magnitude 3 in the direction of [tex]\vec v = 12\,\hat{i}-5\,\hat{k}[/tex].

Step-by-step explanation:

Let be [tex]\|\vec u\| = 3[/tex] and [tex]\vec v = 12\,\hat{i}-5\,\hat{k}[/tex], the resultant in the direction of [tex]\vec v[/tex] can be obtained by using the following expression:

[tex]\vec u = \frac{\|\vec u\|}{\|\vec v\|} \cdot \vec v[/tex]

Where:

[tex]\|\vec v\|[/tex], [tex]\|\vec u\|[/tex] - Norms of [tex]\vec v[/tex] and [tex]\vec u[/tex], respectively.

Now, we get the norm of [tex]\vec v[/tex] by Pythagorean Theorem:

[tex]\|\vec v\| = \sqrt{12^{2}+(-5)^{2}}[/tex]

[tex]\|\vec v\| = 13[/tex]

The vector is now determined:

[tex]\vec u = \frac{3}{13} \cdot (12\,\hat{i}-5\,\hat{k})[/tex]

[tex]\vec u = \frac{36}{13} \,\hat{i}-\frac{15}{13}\, \hat{k}[/tex]

The vector of magnitude 3 in the direction of [tex]\vec v = 12\,\hat{i}-5\,\hat{k}[/tex].

Answer:

Definition: The associative property states that you can add or multiply regardless of how the numbers are grouped. By 'grouped' we mean 'how you use parenthesis'. In other words, if you are adding or multiplying it does not matter where you put the parenthesis.

The word "commutative" comes from "commute" or "move around", so the Commutative Property is the one that refers to moving stuff around. For addition, the rule is "a + b = b + a"; in numbers, this means 2 + 3 = 3 + 2. For multiplication, the rule is "ab = ba"; in numbers, this means 2×3 = 3×2.

Step-by-step explanation:

If you're using PLATO this is the correct answer I just did the problem myself

I'll even explain below and drop the image screenshot

The equation x2 − 36 can be factored into (x − 6)(x + 6) using the difference of two squares.

The equation 9x2 − 1 is the difference of two squares, (3x)2 – 12, so it factors into (3x − 1)(3x + 1).

We can factor 4 out of the expression 4x2 − 16 to get 4(x + 2)(x − 2).

The pairs are:

Hope it helps yuh

The correct answer is 60%

Explanation:

A percentage represents a proportion of a total or 100% by using a number from 1 to 100. In this context, the first step is to count how many squares there are and how many were painted. This leads to the following results:

40 squares in total

24 painted squares

Knowing these two details it is possible to calculate the percentage. Follow this process:

- Write the values

40 squares = 100 % or total

24 squares = x (the value that needs to be found)

- Cross multiply to create an equation and solve this equation

40 x = 2400

x = 2400 ÷ 40

x = 60

The percentage that was painted was 60%

Answer:

$96 is the original price of  book

Step-by-step explanation:

keep the unknown value as X

(19.2/X)*100 = 20%

19.2/X = 0.2

19.2/0.2 = X

X = 96

The original price of the book is $24.

When there is a sales, the price of items become cheaper. Items become less expensive when there is a sale.

When there is a 20% reduction in the price of the book, the book becomes 80% (100 - 20%) cheaper. In order to determine the original price of the book, divide the sales price by 80%

Original price = $19.20 / 80%

= $19.20 / 0.8

= $24

8/9 is the correct answer for you problem

1 by 3 + 5 by 9 is equal to 8 by 9 this is your answer thank you

Answer and Step-by-step explanation:

A) For the model to be a probability distribution, it has to follow two conditions:

1) The probability of each value of the discrete random variable is between, and included, 0 and 1:

2) The sum of all probabilities is 1;

In the table shown, the probabilities are from 0 to 0.3 - between 0 and 1;

Adding the probabilities: 0 + 0.3 + 0.1 + 0.3 + 0.3 = 1

Therefore, this model is a valid probability distribution model.

B) They are discrete because each value correspond to a finite number of possible values.

C) Expected value is calculated by

[tex]E(X) = \Sigma xP(x)[/tex]

[tex]E(X) = 0.0 + 1*0.3 + 2*0.1 + 3*0.3 + 4*0.3[/tex]

E(X) = 2.6

D) P(X=3) = P(3), which means probability of 3:

P(X=3) = 0.3

E) P(X<4): probabilities of values of X that are less than 4:

P(X<4) = P(0) + P(1) + P(2) + P(3)

P(X<4) = 0 + 0.3 + 0.1 + 0.3

P(X<4) = 0.7

F) P(X>0) = P(1) + P(2) + P(3) + P(4)

P(X>0) = 0.3 + 0.1 + 0.3 + 0.3

P(X>0) = 1

G) P(X=5) = P(5)

There is no probability of P(5) because the model doesn't "cover" that number.

H) P(X=0) = P(0)

P(X=0) = 0

I) The total area of any density curve is 1 because it represents all the possible values a variable can assume.

The answers are given as- A) Model is a valid probability distribution model.

B ) The described random variable is discrete.

C ) Mean E(X) = 2.6

D)  P(X=3) = 0.3

E )  P(X < 4) = 2.6

F )  P(X > 0) = 1

G ) There is no probability of P(5)

H ) P(X = 0) = 0

I ) The total area of any density curve is 1

Probability is defined as the ratio of the number of favorable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.

A) For the model to be a probability distribution, it has to follow two conditions:

In the table shown, the probabilities are from 0 to 0.3 - between 0 and 1;

Adding the probabilities: 0 + 0.3 + 0.1 + 0.3 + 0.3 = 1

Therefore, this model is a valid probability distribution model.

B) They are discrete because each value correspond to a finite number of possible values.

C) Expected value is calculated by

E(x) = ∑ P(x)

E ( x) = 0 + ( 1 x 0.3 ) + ( 2 x 0.1 ) + 3 ( 0.3 ) + 4 ( 0.3 )

E(X) = 2.6

D) P(X=3) = P(3), which means a probability of 3:

P(X=3) = 0.3

E) P(X<4): probabilities of values of X that are less than 4:

P(X<4) = P(0) + P(1) + P(2) + P(3)

P(X<4) = 0 + 0.3 + 0.1 + 0.3

P(X<4) = 0.7

F) P(X>0) = P(1) + P(2) + P(3) + P(4)

P(X>0) = 0.3 + 0.1 + 0.3 + 0.3

P(X>0) = 1

G) P(X=5) = P(5)

There is no probability of P(5) because the model doesn't "cover" that number.

H) P(X=0) = P(0)

P(X=0) = 0

I) The total area of any density curve is 1 because it represents all the possible values a variable can assume.
