Answer:
The median number of push-ups is 8.
Step-by-step explanation:
We use the median to find the "middle" value of a sample, that is, the value separating the lower half from the upper half of the sample.
If the size of the sample is even
1,2,3,4
Both the upper half and the lower half should have the same size.
In this case, it is not possible to select only one value which respects this condition. So the mean between 2 and 3 = 2.5 is calculated. This value is not part of the sample.
If the size of the sample is odd
1,2,3,4,5
For a n-sized sample, with n odd, the median is the value at the position (n+1)/2. So her, it is 3, the value at the third position. In this case, it is always going to be an element at a position in the sample, that is, an element of the sample.
In this question:
Initially, we list the number of pushups sorted in an increasing way.
6,8,8,14,18
The size of the sample is 5.
The median value is at the position (5+1)/2 = 3.
So it is 8, which is the element at the 3rd position.

IT ISN'T 2.5 OR 1.5
Answer:
The weight of the box of candies is 1.5b kg greater than the weight of the watermelon.
Step-by-step explanation:
Let's begin by listing out the variables we were given:
weight of the watermelon = b (kg),
weight of watermelon = (2/5) * weight of candies
weight of candies = 1 ÷ (2/5) = 1 ÷ 0.4
weight of candies = 2.5b (kg)
How much is the weight of the box of candies greater than the weight of the watermelon is given by:
weight of the box of candies - weight of watermelon= 2.5b - b = 1.5b (kg)
Therefore, the weight of the box of candies is greater than the weight of the watermelon by 1.5b (kg)

Find the area of the shaded segment of the circle.
Answer:
Around 55.9
Step-by-step explanation:
The first step is to find the area of segment of the circle. Since the segment is a 90 degree angle and a total circle is 360, it is a quarter of the area of a circle. Therefore, you can find its area with the formula [tex]\frac{1}{4}\pi r^2=49\pi[/tex]. Now, you can find the area of the triangle inside. Since all of the radii in a circle are the same length, the triangle has two sides of length 14. Using the triangle area formula, you get an area of 14*14/2=98 square centimeters. [tex]49\pi-98\approx 55.9[/tex] square centimeters. Hope this helps!

There are 43 students in a classroom with 5
tables. If 8 students can sit at a table, how
many students cannot sit down at tables?
5
Answer:
3
Step-by-step explanation:
8 x 5 = 40
43 - 40 = 3
The number of students who cannot sit at tables based on the given conditions in a classroom setting are 3.
The number of students who cannot sit at tables can be calculated as follows:
Number of students per table = 8
Total number of students = 43
Total number of students that can be accommodated by tables = 5 tables x 8 students = 40 students
Number of students who cannot sit at tables = Total number of students - Total number accommodated by tables = 43 - 40 = 3 students

A pair of jeans costs $34.00. You have a coupon for 30% off the regular price. What is the new price of the jeans after you use your coupon?(Hint. This is a two step problem. You will have to multiply and subtract) *
To find the new price of the jeans after using a 30% off coupon, multiply the original price by the discount percentage and subtract that amount from the original price.
Explanation:To find the new price of the jeans after using the 30% off coupon, you need to multiply the original price by the discount percentage and subtract that amount from the original price. Here's how:
Calculate the discount amount by multiplying the original price ($34.00) by the discount percentage (30% or 0.30). The discount amount is $34.00 * 0.30 = $10.20.Subtract the discount amount from the original price to find the new price of the jeans. $34.00 - $10.20 = $23.80.Therefore, the new price of the jeans after using the coupon is $23.80.

y is directionally proportial to x, when y = 30 and x = 6, work out an equation connecting x and y
Answer:
y = 5x
Step-by-step explanation:
The standard equation for directly proportional equations is y = kx. We can see that y is directionally proportional to x when y = 30 and x = 6 and we need to work out an equation connecting x and y.
→ First step is to substitute in the values
y = k × x
30 = k × 6
→ Divide both sides by 6 to isolate k and find the value of k
5 = k
k = 5
→ Now we substitute k = 5 back into y = kx
y = 5x
Answer:
y=5x
Step-by-step explanation:
The answer is y=5x hope you have a nice day!
45% of the 6th graders at Dutchtown Middle went to the Valentine's Dance. If 126 students went to the dance, how many 6th grade students are there at Dutchtown Middle?
Answer: 280
To find the total number of 6th grade students at Dutchtown Middle, we can set up a proportion based on the information given:
- 45% of the 6th graders went to the Valentine's Dance.
- 126 students attended the dance.
Let us denote the total number of 6th grade students as N.
Given that 45% of the 6th graders is equal to 126 students, we can write the equation as:
(45/100)N = 126
[tex]\[ 0.45N = 126 \][/tex]
[tex]\[ N = \frac{126}{0.45} \][/tex]
[tex]\[ N = \frac{126}{0.45} \]\[ N = 280 \][/tex]
Therefore, the total number of 6th grade students at Dutchtown Middle is 280.

A theatre sells two types of tickets to their plays; children’s tickets and adult tickets. For today’s performance they have sold a total of 1180tickets. Also, the have sold 80 more adult tickets than children’s tickets. How many adult tickets have they sold?
Answer:
630
Step-by-step explanation:
Let the number of adult tickets be a.
Let the number of children tickets be c.
For that day's performance, they have sold a total of 1180 tickets. That means that:
a + c = 1180 _____________ (1)
Also, they have sold 80 more adult tickets than children’s tickets.
This means that:
a = c + 80 ______________(2)
Putting (2) in (1):
c + 80 + c = 1180
2c + 80 = 1180
Collecting like terms:
2c = 1180 - 80
2c = 1100
c = 1100 / 2 = 550
From (2):
a = 550 + 80
a = 630
They sold 630 adult tickets.
Final answer:
The theatre has sold 630 adult tickets after solving a system of equations based on the given conditions of total tickets sold and the difference between adult and children's tickets.
Explanation:
The student is presented with a problem where a theatre sells two types of tickets: children's and adult's tickets. For a particular performance, a total of 1180 tickets were sold, and there are 80 more adult tickets sold than children's tickets. We can let 'x' represent the number of children's tickets sold, and thus 'x + 80' will represent the number of adult tickets sold. According to the information given:
x + (x + 80) = 1180
Solving for 'x' we get:
2x + 80 = 1180
2x = 1100
x = 550
Now, to find the number of adult tickets sold, we add 80 to the number of children's tickets.
x + 80 = 550 + 80
x + 80 = 630
Therefore, the theatre has sold 630 adult tickets.

The Pyramid Arena in Memphis, Tennessee is about 98 meters tall
and has a square base with a side length of about 180 meters. A prism-shaped
building has the same square base as the Pyramid Arena. What is the height of
the building if it has the same volume as the Pyramid Arena?
Answer:
Height of the building is 32.67 meters.
Step-by-step explanation:
Volume of a Pyramid = [tex]\frac{1}{3}(\text{Area of the rectangular base})(\text{Height})[/tex]
Side of the square base of the Memphis pyramid = 180 m
Height of the pyramid = 98 meters
Volume = [tex][\frac{1}{3}(180)^2](98)[/tex]
= 1058400 cubic meters
Another building having the same base and volume, is in the shape of a prism.
Therefore, Volume of the pyramid = volume of the building(prism) = 1058400 cubic meters
Volume of the prism = (Area of the base) × height
1058400 = (180)²h
h = [tex]\frac{1058400}{180\times 180}[/tex]
h = 32.67 meters
Therefore, height of the building in the prism shape is 32.67 meters.
