By applying the supplementary angle theorem, the magnitude of angle EBF (m<EBF) is equal to 60°.
What is a supplementary angle?A supplementary angle can be defined as two (2) angles or arc whose sum is equal to 180 degrees.
Mathematically, a supplementary angle can be calculated by using this formula:
Q + R = 180
Where:
Q and R are measure of the angles subtended.
Substituting the given parameters into the formula, we have;
m<EBC + m<ABE = 180
3y + 10 + 2y - 20 = 180
5y - 20 = 180
5y = 180 + 20
5y = 200
y = 200/5
y = 40
Now, we can determine the magnitude of angle EBF (m<EBF) based on the given diagram:
m<ABE = m<EBF
m<EBF = 2y - 20
m<EBF = 2(40) - 20
m<EBF = 80 - 20
m<EBF = 60°

common denominator in math's:Any arithmetic operation involving two or more fractions, such as addition or subtraction, is achievable if the denominators of both fractions are equal. This is referred to as the common denominator. A common denominator is an integer that has at least one element in common with both denominators other than 1.
According to the given data:Given:
3 /10 red + 11 /15 blue makes 1 1/30 purple
Get a common denominator of 30
3/10 * 3/3 = 9/30 red
11/15 *2/2 = 22/ 30 blue
1 1/30 = 31/30 purple
the amount of paint required to make 3 fluid ounce of purple color of paints:
So,
((3/10) * (31/30)) * 3

which expression uses the greatest common factor and the distributive property to rewrite the sum 75 45?
Answers
The expression uses the greatest common factor and the distributive property to rewrite the sum 75+45 is 15(5+3)
The greatest common factor is the greatest factor that divides both numbers.
The distributive Property States that when a factor is multiplied by the sum/addition of two terms, it is essential to multiply each of the two numbers by the factor, and finally perform the addition operation
Given,
75=3×5×5
45=3×3×5
The greatest common factor = 3×5=15
Then,
(75+45)=15(5+3)
Hence, the expression uses the greatest common factor and the distributive property to rewrite the sum 75+45 is 15(5+3)

A continuous probability distribution is characterized by:_____.a. a continuum of possible values. b. an array of individual values. c. counts. d. a list of possible values.
Answers
Option (b), “a continuum of possible values” is the correct option.
The concepts of continuous probability distribution and normal distribution are used here to solve this problem.
The continuous probability distribution can be defined as the probability distribution of a continuous random variable. Normal distribution is used for finding the probability of a continuous variable when the data is more or less symmetric. The probability of being less than or more than some value can be calculated by calculating the area of the curve to the left of that value.
The probability of a continuous random variable will assume a particular value is zero. Consider a continuous random variable, which follows normal distribution with a mean, and a standard deviation, which can be represented as to calculate the probability for a random variable, convert the variable into a standard normal variable by the transformation:
Option (a), “an array of individual values” is incorrect because the continuous probability distribution does not contain an array of individual values. Option (c), “a list of possible values” is incorrect because it is not just a list of possible values. Option (d), “counts” is incorrect because the counts is not a characterized by the continuous probability.
Probability is defined as a task that cannot be completed.True or FalseFalse
Probability can be defined as the likelihood or chance of an event occuring. Probability is a branch of Mathematics that deals with the calculation on the chances of happening of a particular event.

step 2: Cancel multiplied terms that are in the denominator

Answers
The sample mean of snowfalls in the 18 midwestern cities of the United States is 24. This is calculated by applying the formula of arithmetic mean or average to the given sample of data.
What is arithmetic mean?
An arithmetic mean is examined as very similar to an average. Mathematically, it is obtained by dividing the sum of all objects by the total number of objects.
Calculation of the sample mean for given data
Given the total number of cities = 18
The total amount of snow falls = 20 + 40 + 31 + 7 + 15 + 29 + 25 + 20 + 17 + 32 + 28 + 12 + 34 + 29 + 20 + 17 + 33 + 23
The sample mean = total amount of snowfalls / total number of cities
= 432 / 18
= 24
Hence, the sample mean of the given data is 24.

The distance between two points is the length of the line that will join these two points. The distance can be calculated by taking the square of the difference of the x-coordinates and y-coordinates of the two points, adding them up and taking their square root. In order to understand the formula we have to draw a right angled triangle using these two points, where the line joining the points is the hypotenuse, the difference in the x-coordinates is the base and the difference between the y-coordinates is the height. We use Pythagoras' theorem to find the hypotenuse which gives us the formula of distance between two points

Step-by-step explanation:
The equation c = 7.95b represents the total cost of the boxed lunches
c represents the total cost
b represents the number of boxed lunches
To find the total cost of multiple items, you generally multiply the cost of a single item by the number of items there are.
Using this, we can find the cost per item is 7.95 dollars, or 7 dollars and 95 cents.
Do 108.90 divided by 11 to get the price of one of the boxes then multiply it by 17

The nominal interest rate to plug in will be 0.085.
What is interest rate?
An interest rate indicates how expensive borrowing is or how lucrative saving is. Therefore, if you are a borrower, the interest rate is the sum you pay for borrowing money and is expressed as a percentage of the overall loan amount.Given to us, the nominal rate is 8.5%,
The value to plug into your equation,
The equation can be simple interest or compound interest in both cases the value of the nominal rate to the plugin will be the same.
Thus, the nominal rate is 8.5% can be written as
Nominal rate = 8.5%
