Answer:
Mean: 49
Median: 41
Mode: 45
Range: 70
Step-by-step explanation:
To find the mean: add up all the numbers, then divide by how many numbers there are.
To find the median:
Arrange your numbers in numerical order.
Count how many numbers you have.
If you have an odd number, divide by 2 and round up to get the position of the median number.
If you have an even number, divide by 2. Go to the number in that position and average it with the number in the next higher position to get the median.
To find the mode: The mode of a data set is the number that occurs most frequently in the set.
To find the range: The range is the difference between the smallest and highest numbers in a list or set. To find the range, first put all the numbers in order. Then subtract (take away) the lowest number from the highest.

Given right triangle ABC with altitude BD drawn to hypotenuse AC. If AD = 25
and DC 25, what is the length of BD?
Answers
Answer:
25
Step-by-step explanation:
The required value of altitude BD is 25 units, which is determined by the geometric theorem.
What is the right triangle?A right triangle is defined as a triangle in which one angle is a right angle or two sides are perpendicular.
As we know that the geometric theorem states that h = √(ab),
where h is the altitude of a right triangle, a and b are the segments formed when the altitude divides the hypotenuse of a right triangle.
We have to determine the value of altitude y
As per the given figure, a = 25, and b = 25
Substitute the values in the formula, and we get
x = √(25 × 25)
x = √625
x = 25
Therefore, the measure of BD = 25.

While mike was visiting his sister in arlington,he bought an aquarium that was marked down 60% from an original price of $100 .if the sales tax in Arlington is 5% ,what was the total cost of the arquarium?
Answers
Answer:
The cost of the aquarium was $38
Step-by-step explanation:
I got 60% of 100 and it was 60 so it was $40 but then the sales tax was $2 so I subtracted and got 38
The total cost of the aquarium is the sum of the marked down price and
the sales tax.
The total cost of the aquarium is $42
Reasons:
The known information are;
Original price of the aquarium = $100
The marked down percentage of the aquarium = 60%
The sales tax = 5%
[tex]Mark \ down = \dfrac{Difference}{Current \ selling \ price} \times 100[/tex]
[tex]60 \% = \dfrac{Difference}{100} \times 100[/tex]
Which gives;
The difference in sale = $100 - Marked down price = $60
Marked down price = $100 - $60 = $40
The marked down price = $40
The tax is applied to the marked down price, therefore, we get;
Sales tax = 5% × $40 = $2
The total cost = Marked down price + Sales tax
The total cost of the aquarium = $40 + $2 = $42

1) Mark and Huong are selling flower bulbs for a school fundraiser. Customers can buy packages
tulip bulbs and packages of crocus bulbs. Mark sold 9 packages of tulip bulbs and 1 package of
crocus bulbs for a total of $127. Huong sold 6 packages of tulip bulbs and 6 packages of crocus
bulbs for a total of $186. Find the cost each of one package of tulips bulbs and one package of
crocus bulbs.
Answers
Answer:
Package of tulip bulbs = $12
Package of crocus = $19
Step-by-step explanation:
Let b = cost of a package of bulbs
c = cost of a crocus package
Mark: (1) 9b + c = 127 Huong: (2) 6b + 6c = 186
c = 127 - 9b 6b + 6(127 - 9b) = 186
6b + 762 - 54b = 186
- 48b = -576
b = 12
c = 127 -9(12)
c = 127 - 108 = 19

Simon wants to earn as many points as possible in one turn in a game. Two number cubes whose sides are numbered 1 through 6 are rolled. He is given two options for the manner in which points are awarded in the turn.
OPTION A: If the sum of the rolls is a prime number, Simon receives 15 points.
OPTION B: If the sum of the rolls is a multiple of 3, Simon receives 12 points.
Which statement best explains the option he should choose?
A. Simon should choose Option B. The mathematical expectation of this option is 6.25 and is the greater mathematical expectation of the two options.
B. Simon should choose Option A. The mathematical expectation of this option is 6.25 and is the greater mathematical expectation of the two options.
C. Simon should choose Option B. The mathematical expectation of this option is 4 and is the greater mathematical expectation of the two options.
D. Simon should choose Option A. The mathematical expectation of this option is 4 and is the greater mathematical expectation of the two options.
Answers
Answer: b. Simon should chose option a. The mathematical expectation of this option is 6.25 and is the greater mathematical expectation of the two options.
Statement B. Simon should choose Option A. The mathematical expectation of this option is 6.25 and is the greater mathematical expectation of the two options is correct.
What is probability?It is defined as the ratio of the number of favourable outcomes to the total number of outcomes, in other words, the probability is the number that shows the happening of the event.
The probability that the sum of the rolls is a prime number:
P(sum is prime) = 15/36 =0.416
Expected number of points = 0.416×15 =6.25
Probability that f the sum of the rolls is a multiple of 3,
P(sum of rolls is multiple of 3) = 12/36 = 0.33
Expected number of points = 0.33×12 = 3.96
Thus, statement B. Simon should choose Option A. The mathematical expectation of this option is 6.25 and is the greater mathematical expectation of the two options is correct.

Here is how we can approach this problem in a step by step solution:
Look at what we are given - we know that the triangle is a right triangle (has a square on one of its angles representing 90 degrees), and the hypotenuse (the side opposite 90 degree angle) is 2 units long, and one of the other angles is 45 degreesUsing this information about angle measurements, we can solve for the third angle using the sum of angles in a triangle equals 180 degrees theorem: 180 - 90 - 45 = 45. After solving, we get that the final angle is 45 degreesNow, we know that the angles of the triangle are 90, 45, and 45 degrees. Using the base angle theorem, we know that his triangle must be an isocoles right triangleThat means that both legs of the triangle must be congruent (x = y)Finally, we can use the Pythagorean theorem because this is a right triangle to solve for the missing sides 4 = x^2 + y^2, 4 = 2 + 2, x = sqrt (2) y = sqrt (2)*Also, if you knew that a 45-45-90 triangle's sides form a ratio of a, a, and sqrt (2) a, you could also use that and substitute in the values to solve. Both ways work! Hope this helps!!
