A popular art teacher at a school asks a sample of students if they would be interested in taking an art class next year. Of the 30 students he asks, 85% are in one of his art classes this year. Only 15% of the students in the school are in one of his art classes this year. Will this sample be biased? *
Yes, because students who are in one of his art classes this year will be more likely to take one of his art classes next year.
No, because students who are in one of his art classes this year will be less likely to take one of his art classes next year.
Yes, because students who are in one of his art classes this year will be less likely to take one of his art classes next year.
No, because students who are in one of his art classes this year will be more likely to take one of his art classes next year.
Answer:
Yes, because students who are in one of his art classes this year will be less likely to take one of his art classes next year.

City Average Amount of Rainfall Abilene, TX 23.87 inches (in) Brownsville, TX 27.41 in Corpus Christi, TX 23.87 in Houston, TX 27.38 in Wichita Falls, TX 25.44 in If a meteorologist wanted to provide one number that explains how much the rainfall might differ amongst the given cities, which measure should the meteorologist provide and why? Group of answer choices
Mean; this will determine the average amount of rainfall all of the cities received.
Median; this will provide one measurement that provides the middle number of the measurements.
Mode; this will provide one measurement that occurred most frequently.
Range; this will determine the difference between the city with the least rainfall and the city with the greatest rainfall.
A Ferris wheel rotates three times when it travels 235.5 feet. Find the diameter of the Ferris wheel. Use 3.14 for pi
Answer:
try 3.14 x 3.14 / 235.5 and that should be your awnser.
Step-by-step explanation:
the equation for diameter is d=2r which is pi times pi divided my the number. if i remeber correctly. lmk if im wrong
Answer: The diameter is 10cm
Step-by-step explanation:
First, we divide 78.5/3.14 which = 25
Now, we find the square root of 25 to find the radius, which is 5.
The radius is 5cm, which means that the diameter is 10cm.
The diameter of the Ferris wheel is 10cm.
If we recalculate the area again with the diameter given, we can see that:
AREA = 3.14r2
AREA = 3.14 x 5 squared ( radius is half diameter )
AREA = 3.14 x 25 = 78.5

Answer:

Step-by-step explanation:
Simplifying
41n(7x) = 8
Remove parenthesis around (7x)
41n * 7x = 8
Reorder the terms for easier multiplication:
41 * 7n * x = 8
Multiply 41 * 7
287n * x = 8
Multiply n * x
287nx = 8
Solving
287nx = 8
Solving for variable 'n'.
Move all terms containing n to the left, all other terms to the right.
Divide each side by '287x'.
n = 0.02787456446x-1
Simplifying
n = 0.02787456446x-1

A box of cereal measures 8 in by 3 in by 10 in. 80% of it is filled with cereal. How much cereal is in the box?
Answer:
192
Step-by-step explanation:
The area of the cereal box = 8 x 3 x 10 = 240
Therefore, if 100% of the box is filled with
cereal, the amount of cereal in the box
will be 240.
now, 80% is x
80/100 = x/240
cross multiplying,
100x = 80×240
100x = 19 200
dividing both sides by 100
x = 192
Answer:
192
Step-by-step explanation:
please help meee........
Answer:
Bro i dont know if i am right but here we go
The answer most likely is 80
Step-by-step explanation:
By useing a bit of geometry instead of useing two angles to find your last angle.
So first notice how there are two of the same sides (14)but one differnt side(18) okay nice
With that info it is clear that it is a isosoles triangle (triangle with two equal sides and angles) so from that information two of the angles are gonna be the same. Luckely you were given an angle.
So that means there are two 50 angels and an X angle and to solve for X angle you need to add 50 + 50 = 100 then subtract to 180 then boom 80
I hope you understand and im sorry if this is wrong.

Swewed left
Step-by-step explanation:
I know this because most of the data is on the left and not many on the right. And in the graph the mean is less than the median so by that you can know it's left skewed because left skewed is also known as negative sweked and I use that to help me since less and negative have a link.

What comes next in this pattern? (add 4/6)
1/6, 5/6, 1 3/6, ...
A.1 5/6
B.2 2/6
C.2 4/6
D.2 1/6
Answer:
D. 2 1/6
Step-by-step explanation:
To visualize the problem easier, start by converting all the fractions to improper fractions, this will allow you to just add the denominators and simplify the question:
1/6, 5/6, 1 3/6 —> 1/6, 5/6, 9/6
Now that the sequence is rewritten, you can simply add 4 to the numerator, which equals 13/6.
Rewrite this again by finding how many times 6 goes into 13, and use the remainder as the numerator of the new fraction, which will end up as 2 1/6.
At 5 P.M., the total snowfall is 5 centimeters. At 11 P.M., the total snowfall is 12 centimeters. What is the mean hourly snowfall? Write your answer in simplest form as a fraction or mixed number.
The mean snowfall is (BLANK) centimeters per hour.
Answer:
The mean snowfall is 1 centimeter per hour
Step-by-step explanation:
The snowfall is measured over 7 hours.
Between then there is 7 cm of snow that fell
7 / 7 = 1
1cm per hour
Luz drives at an average speed of 60 miles per hour.
She has driven for 2 hours and has traveled a distance of 120 miles.
This situation can be represented with a linear equation written in point-slope form, where x represents the number of hours and y represents the number of miles.
Use this information to complete each statement about the linear equation
Answer:
1) This linear equation has a slope of 60
2) (2, 120)
3) [tex]y - 120 = m(x - 2)[/tex]
Step-by-step explanation:
1) This situation represents a linear time-distance relationship where:
x represents the time
y represents the distance travelled
Slope is equal to △y/△x
Substituted form: [tex]\frac{120}{2}[/tex]
Slope is equal to 60.
2) Using the statement:
She has driven for 2 hours and has traveled a distance of 120 miles, we know that knowing that x represents the time and y represents the distance:
A possible coordinate is (2, 120)
3) Using the point slope standard equation and our known values, we can substitute the values. The correct answer is y - 120 = m(x - 2)
Help! Find the answers and explain the work | max points!
Answer:
1) r = 20.2/2
= 10.1 mm
circumference = ( (1/2) (2) (π) (10.2) )
= 32.04 mm
perimeter = (3.1 + 3.1 + 20.2 + ( (1/2) (2) (π) (10.2) )
= 58.13 mm
2) circumference = (1/4) (2) (π) (307.34)
= 482.77 mm
perimeter = (11.5 + 11.5 + (2 * 10.1) + ( (1/4) (2) (π) (307.34) )
= 525.97 mm
3) circumference = (3/4) (2) (π) (2.5)
= 11.78 cm
4) circumference = (3/4) (2) (π) (2.5)
= 23.56 cm
5) circumference = (1/2) (2) (π) (32)
= 100.53 cm
6) r = 6/2 = 3 cm
circumference = (1/2) (2) (π) (3)
= 9.42 cm
perimeter = (2 + 2 + 6 + ( (1/2) (2) (π) (3) )
= 19.42 cm
