Which fraction is greater than the fraction represented by the model?
1/4
7/16
1/8
3/16
Answer:
7/16
Step-by-step explanation:
If it's easier to visualize, we can convert every into 1/16 including the graph to compare.
To convert the graph (currently in 1/8), we divide each segment to produce 16 segments, 6 of which are shaded (6/16 = 3/8).
The other fractions converted to 1/16 are as follows:
1/4 --> 4/16
7/16 --> 7/16
1/8 --> 1/16
3/16 --> 3/16
Now it's easy to tell which fraction is greater than the area represented in the model!
How can you tell when to multiply and make boxes vs to simply combine like terms?
You can multiply ANYTHING. Just make sure that when you multiply, you change the exponents properly. Combining like terms is basically like normal addition. For example, you cannot add 6x +3y because they have different variables. If it was 3x+6x, then you can add it because they are like terms.
Hope this helps! Comment if you have any questions!

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

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.

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)

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].

The shaded area on the grid represents the part of the rectangular wall that was painted. Each small square on the wall has the same dimensions. Which percentage of the wall was painted?
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%

Complete Question
The complete question is shown on the first uploaded image
Answer:
The correct option is C
Step-by-step explanation:
The correct option is
The firm should forget the new product, accept the loss of the investment and work on innovations that show signs of being more profitable.
The reason for this is that the period that the company is to recover the funds allocated to R &D is over i.e the patent(which is one of the most via way to recover their funds only last for one year so investing more resource on the product will lead to more loss for the company instead of a gain

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]]

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.
