Answer:
Calculating the means:
Sum each length from each sample and divide it by the number of worms.
Sample 1: 26 + 25 + 27 + 19 + 24 + 26 = 147/6 = 24.5
Sample 2: 24 + 23 + 24 + 26 + 25 + 25 = 24.5
They each have the same sample mean.
Ranges: Take the largest length and subtract the smallest.
Sample 1: 27 - 19 = 8
Sample 2: 26 - 23 = 3
Sample 1 has a greater range.

Cheryl painted her living room walls with two different colors. She painted part of the room yellow and another part green. If the surface area of the walls in her room is 720 ft2 and she painted 288 ft2 yellow, what percent of the room did she paint green?
Answer:
Total percent of the room did she paint green = 60%
Step-by-step explanation:
Given - Cheryl painted her living room walls with two different colors. She painted part of the room yellow and another part green. If the surface area of the walls in her room is 720 ft² and she painted 288 ft² yellow.
To find - What percent of the room did she paint green ?
Proof -
Given that,
The surface area of the walls in her room = 720 ft²
Total area painted in yellow color = 288 ft²
So,
Total area painted in green color would be = 720 - 288 = 432 ft²
Now,
Let the total percent green color painted = x
So,
720 × x% = 432
⇒[tex]720*\frac{x}{100} = 432[/tex]
⇒ x = [tex]\frac{432*100}{720}[/tex] = 60
∴ we get
Total percent of the room did she paint green = 60%
A group of friends were working on a student film. They spent all their budget on equipment and costumes. They spent $737 on equipment, and 33% of the total budget on costumes. What was the total budget for their student film?
Answer:
Budget= $1,100
Step-by-step explanation:
Giving the following information:
They spent $737 on equipment and 33% of the total budget on costumes.
If they spent all their budget on equipment and costumes, then the percentage spent on equipment was 67% (100 - 33).
Then, to calculate the total budget, we need to use the following formula:
Budget= 737 / 0.67
Budget= $1,100
Solve f(x) = 2x + 2 what would f(x)=20
a. 20
b. 10
c. 9
d. 8
Answer:
the answer is c. 9
Step-by-step explanation:
20=2x+2
18=2x
x=9
Answer:
C
Step-by-step explanation:
Given f(x) = 2x + 2 and f(x) = 20, then equate right sides, that is
2x + 2 = 20 ( subtract 2 from both sides )
2x = 18 ( divide both sides by 2 )
x = 9 → C

21 = x/7 + 15
21 - 15 = x/7
6 = x/7
x = 6 × 7
x = 42

Blake, Chang, and Grace together sold 71 tickets for the school banquet. Blake sold 27 tickets and Chang sold 28 tickets. How many tickets did Grace sell? (5 points) 16 43 44 55
Answer:
16
Step-by-step explanation:
because to get what you need add 27 and 28 and you get 55 then subtract 71 by 55 to get 16
71-(27+28)
Answer:
Grace sold 16 tickets.
Step-by-step explanation:
We have a total of 71 tickets sold between 3 people. Blake sold 27 tickets and Chang sold 28 tickets. Adding those sold by Blake and those sold by Chang, gives us: 27 + 28 = 55, if that amount is subtracted from the total sales that are 71 tickets, the result would be: 71 - 55 = 16, which would be the tickets sold by Grace.

How to solve this triangle, please help me.
Answer:
sum of angles in a triangle is 180
so 70+60+ 8x+2 = 180
132+ 8x = 180
8x = 180-132
x = 48/8
x= 6
then find the angle by substituting value of x
8x + 2
8*6 + 2
= 50°
A ball inside of a cube has a volume of 524 cubic inches. If each side of the cube measures 12.75 inches. what is the volume of air inside the cube? (Round to the nearest tenth.)
1) 1548.7 cubic inches
2) 2072.7 cubic inches
3) 2596.7 cubic inches
4) 1048.0 cubic inches
Answer:
1548.7 in³
Step-by-step explanation:
Given that :
Volume of ball = 524 in³
Volume of a cube = s³
Where, s = 12.75 inches
Volume of cube = 12.75 * 12.75 * 12.75 = 2072.671875 in³
The volume of air inside the cube :
(volume of cube - volume of ball)
(2072.671875 - 524) in³
= 1548.671875 in³
= 1548.7 in³ (nearest tenth)
An airline uses many different types of airplanes. Information regarding some of the airplanes is given in the table below. A 5-column table with 5 rows. Column 1 is labeled Plane with entries SkyBus 280, SkyBus 580, Grigson A-2, Grigson A-5, SkyDancer. Column 2 is labeled Number of seats with entries 120, 225, 70, 130, 350. Column 3 is labeled Seat width (inches) with entries 20.3, 20.6, 19.9, 20.5, 20.2. Column 4 is labeled Wi-fi with entries no, yes, no, yes, yes. Column 5 is labeled first-class seats question mark with entries no, yes, no, no, yes. Which of the variables is a continuous variable? number of seats seat width Wi-Fi first-class
Answer:
b took the test right now
Step-by-step explanation:
The required, seat width is the continuous variable in the given table.
What is continuity?Continuity is a mathematical concept that describes the smoothness of a function or a curve. A function is said to be continuous if there are no abrupt changes or breaks in the values it takes as the input varies. More formally, a function f(x) is continuous at a point x = a if the limit of f(x) as x approaches a from both sides exists and is equal to f(a).
For example, a function that describes the temperature in a room as a function of time is continuous if there are no sudden changes or jumps in the temperature.
Here,
The number of seats is not a continuous variable because it can only take discrete values (such as 120, 225, etc.).
The Wi-Fi and first-class variables are not continuous either because they are categorical variables that can only take a limited number of values (yes or no).
The seat width variable, however, is a continuous variable because it can take on any value within a range of values (such as between 19.9 inches and 20.6 inches). Therefore, seat width is the continuous variable in the given table.

What is the answer for x?
Answer:
x = 7°
Step-by-step explanation:
Sum of All angles = 180°
Form an equation
180 - 90 - 36 = 7x + 5
54 = 7x + 5
Subtract 5 from both sides
49 = 7x
x = 49/7
x = 7

Answer:
it is B and D
Step-by-step explanation:
mark brainliest or 5 stars and heart
correct me if im wrong
Answer:
B and A
Step-by-step explanation:
Calculate distance d using the distance formula
d = [tex]\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }[/tex]
(1) with (x₁, y₁ ) = (0, 0) and (x₂, y₂ ) = (6, 8)
d = [tex]\sqrt{6-0)^2+(8-0)^2}[/tex]
= √(6² + 8²)
= √ (36 + 64)
= √ 100
= 10 → B
(2)
Using (x₁, y₁ ) = (- 5, 3) and (x₂, y₂ ) = (3, 15)
d = √ (3 + 5)² + (15 - 3)²
= √ 8² + 12²
= √ 64 + 144
= √ 208
≈ 14.4 ( to the nearest tenth ) → A
