Answer:
15
Step-by-step explanation:
To find the total number of combinations you can make with these four coins, we have to do 2 to the power of the total amount of coins. This because each coin has two choices: to be included in the combination or not. There are 4 total coins, and 2^4 is 16. There are 16 total combinations. But since one of those possibilities are that none of the coins are included, we subtract 1 from the total, and get 15. There are 15 combinations with 1 or more coins, which each give us different amounts.

Kevin uses each of the digits 5, 7, 4 and 9, once and once only, to make
four-digit numbers.
c) What is the largest number that he can make?
d)
What is the smallest even number that he can make?
Answer:
largest number= 9754
smallest number = 4579
Step-by-step explanation:
largest number - 9754
9 is the larger number in 5,7,4,9
7 is the second largest
so you basically count it backwards
smallest number=4579
4 is the smalleat number in 5,7,4,9
so you basically count forward
Given m||n, find the value of x ( x+1) (7x-5)
Answer: If two lines are parallel, it means that they have the same slope. Therefore, to find the value of x in this problem, you need to find the slope of line m and line n, and then set them equal to each other.
The slope of a line can be found using the formula:
slope = (y2 - y1)/(x2 - x1)
In this case, you are given the equation of line m in the form "x + 1", and the equation of line n in the form "7x - 5". To find the slope of each line, you can rewrite these equations in the form y = mx + b, where m is the slope and b is the y-intercept (the point where the line crosses the y-axis).
For line m, we have:
y = x + 1
The slope of this line is m = 1.
For line n, we have:
y = 7x - 5
The slope of this line is m = 7.
Since line m and line n are parallel, their slopes must be equal. Therefore, we can set these slopes equal to each other and solve for x:
1 = 7
This equation has no solution, which means that there is no value of x that will make these two lines parallel. Therefore, the answer is that there is no solution.
Find the annual percentage yield (APY) for the investment. $8000 at 5.75% compounded daily
The annual percentage yield (APY) for the investment $8000 at 5.75% compounded daily is; 5.918%
How to calculate the Annual Percent Yield?
The Annual percentage yield(APY) is defined as the amount of interest you'll earn in one year from a savings account.
Annual percentage yield (APY) is calculated by the usage of the formula;
APY= (1 + r/n )ⁿ – 1
Where;'
r is the said annual interest rate
n is the variety of compounding intervals every year.
Thus, we are given;
r = 5.75% = 0.0575
n = 365 days
Thus;

A retail company is studying how employees are divided by job classification, such as employee, manager, and senior manager. Which of the following displays could be used to represent the data, and why?
Box plot; because job classification is categorical
Box plot; because job classification is numerical
Bar chart; because job classification is categorical
Bar chart; because job classification is numerical
Answer:
Bar chart; because job classification is categorical.
Step-by-step explanation:
Categorical data: Data that can be divided into groups (categories).
Numerical data: Data that is in the form of numbers (also called "quantitative data").
Therefore, "job classification" is categorical data since the classifications such as employee, manager, senior manager, etc. are categories rather than numbers.
Box plots are used to show distributions of numerical data values.
Bar charts are used to show a comparison of values across different categories of data.
Therefore, a bar chart should be used to represent the data as the data is categorical.
Answer:

principal, plus $60 simple interest. What was the annual interest rate?

(7 × 10) + (7 × 10%) + (7 × 10²) = 700 070.07
Write down a possible set of values for x, y and z.
The equation (7 × 10) + (7 × 10%) + (7 × 10²) = 700 070.07 can be rewritten as:
7x + 0.7y + z = 700 070.07
To find a set of values for x, y, and z that satisfies this equation, we can use trial and error. One possible set of values is:
x = 100
y = 10
z = 7000
If we plug these values into the equation, we get:
(7 × 100) + (7 × 0.1) + (7 × 7000) = 700 070.07
Which simplifies to:
700 + 0.7 + 49000 = 700 070.07
This equation is true, so the values x = 100, y = 10, and z = 7000 are a solution to the original equation.
Find the distance between the point (3, 5) and a line with the equation 5x-3y+10=0
The distance between the points (3,5) and a line with the equation 5x-3y+10=0 is 10/√34 units.
Given that,
We have to find the distance between the points (3,5) and a line with the equation 5x-3y+10=0.
We know that,
We have a formula that is
Let (x₁, y₁) be the point and ax + by + c = 0 be the line.
Then the distance between a point and a line will be
d=|ax₁+by₁+c|/√(a²+b²)
Here,
(x₁,y₁)=(3,5)
a=5, b=-3 and c=10
So, substituting
d=|5(3)+(-3)(5)+10|/√(5²+(-3)²)
d=|15-15+10|/√25+9
d=|10|/√34
d=10/√34
Therefore, the distance between the points (3,5) and a line with the equation 5x-3y+10=0 is 10/√34 units.

Augustus Galoop (from Willie Wonka & The Chocolate Factory) LOVED
chocolate. He loved it SO MUCH, he decided to create his very own chocolate
milk He made 30 gallons (he REALLY loves chocolatel). The mixture had to be
perfect, so he started with a recipe of 10% chocolate syrup and 90% milk It
was too weak, so he tried 30% chocolate & 70% milk That was even too
chocolaty for him. "Maybe, If I try 15% chocolate syrup & 85% milk, it'll be
perfect??" So he did, but he forgot how many gallons of chocolate syrup & milk he'd
used for the first two attempts. He DID remember the percentages, though. How
many gallons of chocolate syrup & milk did he use for his final mixture?
Augustus used a total of 12 gallons + 1.8 gallons = 12+1.8=13.8 gallons of chocolate syrup in the three mixtures.
What is a percentage?
Percentages are essentially fractions where the denominator is 100. To show that a number is a percent, we use the percent symbol (%) besides the number. For example, if you got 75 questions right out of 100 on a test (75/100), you would have scored 75%.
Since Augustus used 10% chocolate syrup and 90% milk for the first mixture and 30% chocolate syrup and 70% milk for the second mixture, the total percentage of chocolate syrup he used in the first two mixtures is 10% + 30% = 40%.
Since Augustus made a total of 30 gallons of chocolate milk, he used 30 gallons * 40% =3040.01=12 gallons of chocolate syrup in the first two mixtures.
For the final mixture, Augustus used 15% chocolate syrup and 85% milk. The total percentage of chocolate syrup he used for the final mixture is 15%.
Since Augustus used a total of 12 gallons of chocolate syrup in the first two mixtures, he used an additional 12 gallons * 15% = 1215.01=11.8 gallons of chocolate syrup for the final mixture.
Hence, Augustus used a total of 12 gallons + 1.8 gallons = 12+1.8=13.8 gallons of chocolate syrup in the three mixtures.

What is a measure of arc?
The central angle that creates the intercepted arc's central angle, or the arc measure, is expressed in degrees. Arc length can be estimated as a percentage of the circle's circumference by multiplying the circle's diameter by the arc length, divided by 360.
Here, we have
Given: DR = 4x +4
PR = 50°
The sum of the measure of arc PR + DR = 180°
50° + 4x +4 = 180°
x = 4
