what is the qoutient?
Answer:
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.
Ella is 12.537 miles from her house which shows the value of 12.537 rounded to the nearest tenth and nearest hundredths F 12.6, 12.54 G 12.5, 12.54 H.13.0, 12.53 J 12.5, 12.53
Answer:
12.5 is to the nearest tenth
12.54 is to the nearest hundredth
Step-by-step explanation:
12.537
The first number after the decimal is the tenths place
we look at the number after it to determine whether to round up or down
12.53 the 3 is less than 5 so we leave it alone
13.5 is rounded to the nearest tenth
The second number after the decimal is the hundrdeths place
we look at the number after it to determine whether to round up or down
12.537 the 7 is greather than or equal to 5 so we round up
13.537 is rounded becomes 13.54

Step-by-step explanation:
Solve for x:
3x + 2x + 7 = 10x - 16
What’s 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]

Now,
Here, A two-way ANOVA with interaction.
We know that;
Two-way ANOVA include two factors, each with two or more levels (groups), and collectively, factors are often referred to as the main effects in these types of ANOVA. The other source of variation in a two-way ANOVA is the interaction between the two factors.
Thus, Number of sources of variation = 2

Four students calculated the volume of a 12.8 oz container. Their results are shown in the table. Whose calculation is the most accurate?
A. Wally’s
B. Rex’s
C. Amanda’s
D. Joni’s
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.
The probability distribution of random variable, X, is defined as follows:
X 0 1 2 3 4
Probability 0 0.3 0.1 0.3 0.3
A) Explain if the above is a valid probability model.
B) Is the described random variable discrete or continuous?
C) What is the expected value (mean) of the probability distribution?
D) Calculate P(X = 3).
E) Calculate P(X < 4).
F) Calculate P(X > 0).
G) Calculate P(X = 5).
H) Calculate P(X = 0).
I) What is the total area under any density curve?
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
What is probability?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.

Explain why commutative and associative properties don’t hold true for subtraction and division but the identity properties do ?
Glad I can help you!!
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.

Find a vector of magnitude 3 in the direction of v=12i-5k.
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].
Stephanie buys a book in a sale for $19.20 . This sale price is after a reduction of 20%. Calculate the original price of the book
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
