A die is rolled. The set of equally likely outcomes is {1, 2, 3, 4, 5, 6}. What is the probability of rolling a 6?
Answer:
the probability of rolling a 6 is 1/6
Step-by-step explanation:
because there are six possible outcomes and it is a fair die, each outcome must be equally as likely, therefore there is a 1/6 chance of rolling any number.
Emi is a veterinarian. In a given week, 50% of the 16 dogs she saw were boxers. Antonio is also a veterinarian. In the same week, 7 of the 35 dogs he saw this week were Boxers. Each wants to record the part, the whole, and the percent.
Emi will need to locate the whole in this case because she already has the part and the percentage.
What is a whole?In mathematics, the total number of items being analyzed, in this case, the total number of dogs, is represented by a whole.
The term "part" refers to a quantity that is typically smaller than the total and describes particular qualities. For instance, 20 of the 30 students in a classroom enjoy playing basketball. The part is 20 then.
The relationship between the part and the whole is represented by the percentage, which is a number followed by the symbol%. In this instance, the proportion of boxers and overall dogs are related.
Emi already knows the percentage (50%), the part (16), and the total number of dogs, which in this case is 32, as a result of this.

A bottle maker assumes that 24% of his bottles are defective. If the bottle maker is right, what is the probability that the proportion of defective bottles in a sample of 546 bottles would differ from the population proportion by greater than 4%? Round your answer to four decimal places.
The probability that the proportion of defective bottles in a sample of 546 bottles would differ from the population proportion by greater than 4% is: 10.9069.
What is the probability that the population proportion will be greater than 4%?To obtain the correct value, we need to use the formula for the Z score. This formula requires that we subtract the average or mean value from the data point provided and divide the remaining value by the standard deviation.
Here is the formula:
z = (x-μ)/σ
First population proportion = 0.24
The sample proportion, hat p = 0.04
Z score =
[tex]0.04 - 0.24 / \sqrt 0.24 (1 - 0.24) / 546[/tex]

What is the equation of the line in standard form?
A. x-2y=4
B. x+2y=4
C. 2x+y=2
D. 2r-y-2
Answer:
D. 2x -y = 2
Step-by-step explanation:
You want to know the standard-form equation of the line through points (-1, 4) and (2, 2) as shown on the graph.
Intercept formThe graph shows the x-intercept of the line is a=1, and the y-intercept of the line is b=-2. This means the intercept form of the equation is ...
x/a +y/b = 1
x/1 +y/(-2) = 1
Standard formMultiplying this equation by 2 gives ...
2x -y = 2 . . . . the standard form equation for the line
__
Additional comment
The standard form equation can also be developed from the coordinates of points on the line:
(y2 -y1)x -(x2 -x1)y = (y2 -y1)x1 -(x2 -x1)y1
(2 -(-4))x -(2 -(-1))y = (2 -(-4))(-1) -(2 -(-1))(-4)
6x -3y = -6 +12
Dividing by 3 gives the standard form equation ...
2x -y = 2
A person is selected at random. A is the event “the person selected earns more than $100,000 per year” and B is the event “the person selected earns more than $250,000 per year.”
The pairs of events, A and B, that are disjoint include option A and B.
What are disjoint events?It should be noted that disjoint events simony means the events that are mutually exclusive as they can't occur at the same time.
For option A, because a person can be either male or female but not both, events A and B are disjoint.
For B, because the person already earns more than $100,000, events A and B are not disjoint.
For C, because the sum of two dice cannot be three when one die is three, events A and B are disjoint.

B
a. down payment: $31,500b. amount of mortgage: $178,500c. points paid at closing: $1785d. total cost of interest over 30 years: $227,667Step-by-step explanation:
You want to know the 15% down payment, the mortgage amount, the value of 1 point, and the total interest cost for a 6.5% 30 year loan on a $210,000 home.
Look at the Answer ChoicesThe answer choices all have the down payment as $31,500 and the loan value as $178,500. A "point" is one percent of the loan value (not the home value), so ...
1 point = 0.01 × $178,500 = $1785 . . . . . . eliminates choices A and C
The difference between choices B and D is in the value of the interest paid. Your experience with 30-year loans in this interest rate range tells you that the interest paid is between 1 and 2 times the loan value. That is, the chice $227,667 is more likely correct than the choice $406,167.
Comparing these two numbers, we see they differ by 178,500, which is the value of the loan. That is, we can guess that 406,167 is the total amount repaid, not just the interest.
Answer choice B is the only one that makes sense.
Work the problemIf you like, you can work the problem.
down payment = 15% × $210,000 = $31,500
loan amount = $210,000 -31,500 = $178,500
one point = 0.01 × $178,500 = $1785
The monthly payment is found using the amortization formula:
A = P(r/12)/(1 -(1 +r/12)^(-12t))
A = 178500(0.065/12)/(1 -(1 +0.065/12)^(-12·30)) ≈ 1128.24
The monthly payment amount is about $1128.
So, the total repaid is 360 payments of $1128.24, or $406,167.
The interest paid is this amount less the principal:
interest paid = $406,167 -178,500 = $227,667

Contains the points (5, 3) and (8, 12); slope-intercept form
Answer:
y = 3x + 12
Step-by-step explanation:
y = mx + b
The m is the slope and the b is the y intercept.
Slope:
Change in y over the change in x. The ordered pair is written in the form (x,y)
[tex]\frac{12-3}{8-5}[/tex] = [tex]\frac{9}{3}[/tex] = 3
The slope is 3.
Use the slope of the 3 and the x and y from one of the ordered pairs given. I am going to use the point (5,3), but either point will work
slope 3
x = 5
y=3 Plug these all in and solve for b
y = mx + b
3 = (3)5 + b
3 = 15 + b Subtract 15 from both sides
-12 = b
This is the y intercept
y = 3x - 12
Answer:
Slope-intercept form,
→ y = 3x - 12
Step-by-step explanation:
Formula we use,
→ y = mx + b
The value of slope will be,
→ m = (y2 - y1)/(x2 - x1)
→ m = (12 - 3)/(8 - 5)
→ m = 9/3
→ [ m = 3 ]
Then the value of b will be,
→ y = mx + b
→ 12 = (3)8 + b
→ b + 24 = 12
→ b = 12 - 24
→ [ b = -12 ]
Now the slope-intercept form is,
→ y = mx + b
→ [ y = 3x - 12 ]
Hence, the answer is y = 3x - 12.

B. Acid test is 1.
C. Average days' collection is 26.7 days.
D. Asset turnover is 1.4x.
E. Profit margin on sales is 14.63%.
What are financial ratios?Financial ratios are ratios that show the relative magnitude of one financial account to another.
Financial ratios are used to compare or represent an entity's financial performance or position in relative terms.
Current Ratio = Current Assets ÷ Current Liabilities
= $18,000 ÷ $16,000
= 1.125
Acid Test Ratio = (Current Assets - Inventory) ÷ Current Liabilities
= ($18,000 - 2,000) ÷ $16,000
= $16,000 ÷ $16,000
= 1
Average Days' Collection = Accounts Receivable ÷ Net Sales x 365 days
= $3,000 ÷ $41,000 x 365
= 26.7 days
Asset Turnover = Net Sales ÷ Total Assets
= $41,000 ÷ $29,000
= 1.4x
Profit Margin on Sales = Net Income ÷ Net Sales x 100
= $6,000 ÷ $41,000 x 100
= 14.63%
Current Assets = $18,000
Accounts Receivable = $3,000
Current Liabilities = $16,000
Inventory = $2,000

For each chart below, identify the output rule and classify the function as exponential, linear or neither.
The classification and the output rule for each function in this problem is given as follows:
1. Output rule: y = 5x + 11. Classification: Linear.
2. Output rule: y = 2^x. Classification: Exponential.
3. Output rule: y = 3 if |x| is even, y = 1 if |x| is odd. Classification: Neither.
What defines a linear function?A linear function is defined when the increase of 1 in x result in the addition of a constant to y, hence the rule is:
y = mx + b.
In which:
m is the addition to y when x increases by one.b is the value of y when x = 0.Hence, for the first table, as 5 is added to x when x increases by one, the rule is:
y = f(x) = 5x + 16.
What defines an exponential function?An exponential function is defined when the increase of 1 in x result in the multiplication of a constant to y, hence the rule is:
y = a(b)^x.
In which:
b is the addition to y when x increases by one.a is the value of y when x = 0.Hence, for the second table, the rule is:
y = 2^x.
For the third table, none of the definitions for linear and for exponential functions are true, hence the function is neither, as it is a piece-wise function that assumes one value for odd numbers and another for even numbers.

-2x + 10 + 2x = 4x + 2x --> Addition property of Equality - add 2x to both sides
10 = 6x --> Simplifying
10/6 = 6x/6 --> Division Property of Equality - divide each side by 6
5/3 = x --> Simplifying

Abigail Henderson's budget of $1,360 and the $1.30 and $1.60 trading price of the currency of country A and country B gives;
The equation that represents the total cost is; 1.3·x + 1.4·y = 1,360The number of each currency Abigail plans to buy are;
The number of units of currency of country A, x = 800The number of units of the currency of country B, y = 200What is a budget?A budget provides an estimation of a person, business, or country's income and expenditure over a specified period or duration.
The amount Abigail Henderson budgeted = $1,360
The per currency exchange rate for country A = $1.30
The per currency exchange rate for country B = $1.60
The number of currency A Abigail wants = 4 × The number of currency B
Which gives; x = 4·y
The equation that represents Abigail's total cost of buying currencies is presented as follows;
1.3·x + 1.6·y = 1,360
Plugging in the value of x gives;
1.3 × (4·y) + 1.6·y = 1,360
6.8·y = 1,360
y = 1,360 ÷ 6.8 = 200
The number of currency of country B, Abigail purchases, y = 200
The number of currency of country A Abigail plans to buy, x = 4 × 200 = 800
