Answers
Answer: The median score of Ms. Singh's 20 students is 82.5
Step-by-step explanation: What are mean and median?
The mean is the average value which can be calculated by dividing the sum of observations by the number of observations
Mean = Sum of observations/the number of observations
A Median represents the middle value of the given data when arranged in a particular order.
We are given the Students in Ms. Singh's class had the following scores on their last quiz.
First, we have to arrange the given data in an ordered manner. Thus:
55, 68, 72, 73, 75, 77, 78, 79, 82, 82, 83, 85, 85, 85, 86, 86, 87, 91, 92, 95
The median = the average of the 10th and 11th data
Median = (82 + 83) ÷ 2
Median = 165 ÷ 2
Median = 82.5

A rhombus is a special type of parallelogram in which two pairs of opposite sides are congruent. That means all the sides of a rhombus are equal.
What is the Area of a Rhombus?
The area of a rhombus can be defined as the amount of space enclosed by a rhombus in a two-dimensional space. To recall, a rhombus is a type of quadrilateral projected on a two dimensional (2D) plane, having four sides that are equal in length and are congruent.
Using Diagonals A = ½ × d1 × d2
Using Base and Height A = b × h
Using Trigonometry A = b2 × Sin(a)

Answer: The length of the base of the triangle is, 9.1 inches
Step-by-step explanation: The area of the triangle below is 23.66 square inches.
And, The height = 5.2 inches
We know that;
Area of triangle = 1/2 × Base × Height
Substitute all the values we get;
⇒ 23.66 = 1/2 × Base × 5.2
⇒ 23.66 = Base × 2.6
⇒ Base = 23.66 / 2.6
⇒ Base = 9.1 inches
Explanation: 23.66 times 2 is 47.32 divided by 5.2 is 9.1 and 9.1 times 5.2 is 47.32 divided by 2 is 23.66

|Giving Brianliest| 50+ points|Max had a collection of 1,000 movies at the beginning of the summer. After the summer, Max had traded some of his movies and now he has only 750 movies.
What is the percent decrease of his movie collection?
Answers
Answer:3/4
Step-by-step explanation:duh
To find the percent decrease of Max's movie collection, we need to find the difference between his original collection and his new collection, divide that by his original collection, and then multiply by 100 to express the answer as a percentage.
The difference between his original collection and his new collection is:
1,000 - 750 = 250
So the percent decrease is:
(250 / 1000) x 100% = 25%
Therefore, Max's movie collection decreased by 25%.
Shilo is sharing jellybeans. The jar of jellybeans has a ratio of 32:56. If shilo keeps the ratio the same and gives his friend 7 pink jellybeans, how many green jellybeans would he also share
Answers
Answer:
12 green jellybeans
Step-by-step explanation:
To keep the ratio of 32:56, we need to divide both sides by the greatest common factor.
32 and 56 have a GCF of 8, so we can simplify the ratio to 4:7.
This means for every 4 pink jellybeans, there are 7 green jellybeans.
If Shilo gives 7 pink jellybeans to his friend, he needs to give them 7/4 * 7 = 12.25 green jellybeans. Since he can't give a fractional jellybean, he would need to give his friend 12 green jellybeans

Answer:
199 cm^2
Step-by-step explanation:
1. First, we have to find the radius. Divide the circumference by pi (3.14): 50/3.14=15.92. This gives us the diameter.
2. Divide the diameter by 2: 15.92/2=7.96. This is the radius.
3. Use the formula for the area of a circle. Area=3.14*7.96^2.
4. Solve this equation and you get the answer: About 199 cm^2
Answer:199
Step-by-step explanation:
the formula for the area of a circle is [tex]\pi r^{2}[/tex] (pi *radiusto the power of 2)
so the 50 metered wire is the circumference of the circle
to get the area of the circle you need the radius
to get the radius you need to divide 50 by 3.14 ([tex]\pi[/tex]), that equals to 15.923566879 this is the diameter to get the radius you need to divide it by 2 . radius =7.961783439
formula for area =[tex]\pi r^{2}[/tex]
[tex]\pi[/tex]=3.14
3.14ˣ7.961783439ˣ7.961783439=199.044585975
round it to nearest number = 199

This is an algebraic question. Please use variables to solve!

Jeff=x
Mark=x+4
Rick=x+6
Sum of ages=112
Now that we know this you simply put it into a normal expression:
x+x+4+x+6=112 [Simplify this]
3x+10=112 [Subtract '10']
3x=102 [Divide by 3]
x=34

Using unitary method.
Divide both sides by 55/5 light bulb = $9/5
1 light bulb = $ 1.8
Multiply both sides by 71 × 7 light bulbs = $1.8 × 7
7 light bulbs = $ 12.6[tex]\rule[225]{225}{2}[/tex]

Carmen has two pieces of wire, one 14 feet long and the other 6 feet long. If she wants to cut them up to produce many pieces of wire that are all of the same length, with no wire left over, what is the greatest length, in feet, that she can make them?
please show me how to do greatest common factor
Answers
Answer: the greatest length she can make from the two pieces is 2 feet.
Step-by-step explanation:
To find the greatest length of wire that Carmen can make from the two pieces, we need to find the greatest common divisor (GCD) of the two lengths.
We can start by finding the factors of each length:
14: 1, 2, 7, 14
6: 1, 2, 3, 6
The common factors are 1 and 2. The greatest common factor is therefore 2.
This means that Carmen can cut both pieces of wire into lengths of 2 feet without any wire left over. So the greatest length she can make from the two pieces is 2 feet.
Elpha can't remember her lock combination. It has one letter and one number from 0 - 9.
a. How many different lock combinations are possible?
b. What is the probability Elpha will guess the correct lock combination on her first try?
Answers
Answer: 0.38%
Step-by-step explanation:
Since there is one letter and one number from 0-9, there are 26 possible letters and 10 possible numbers. Therefore, the total number of lock combinations possible is:
26 letters x 10 numbers = 260 combinations
b. Since Elpha has no knowledge of the correct combination and each combination has an equal chance of being correct, the probability of guessing the correct combination on the first try is:
1 / 260 = 0.003846153846153846
Therefore, the probability of guessing the correct lock combination on the first try is approximately 0.38%.
