Ella conducted a survey to find out the amount of time high schoolers spend surfing the Internet. From the data collected, the range of time spent was 1 hour. What does this range say about the data?
- All the students surveyed spend exactly 1 hour surfing the Internet.
- All the students surveyed spend an average of 1 hour surfing the Internet.
- The difference between the greatest amount of time and the least amount of time spent surfing the Internet is 1 hour.
- The quotient between the greatest amount of time and the least amount of time spent surfing the Internet is 1 hour.
WHOEVER KEEPS FALSELY REPORTING MY QUESTIONS AND BLEEDING ME DRY OF POINTS, STOP. YOURE NOT FUNNY
Answer:
the answer is C
Step-by-step explanation:
The answer is C.
Because we do not have any tables graphs etc., we can only use the fact that the range is 1
The definition of range is the difference between the largest amount and the smallest amount. In equation form, it should look like this:
Now lets move to the answer choices:
Answer A. is wrong
If everyone surfed for exactly an hour, the largest amount of time would be 1 hour and the smallest amount of time would also be 1 hour. Put this into the equation and the range would be 0 which is contradicted from the data present
Answer B. is wrong because the range is not the average, the mean is the average. We are looking for the range, not the mean so Answer B. is incorrect.
Answer C. is correct. The range is the difference between the largest and the smallest. In this answer, it tells us that the range is the difference between the greatest amount of time and the least amount of time spent surfing the Internet is 1 hour. This follows the term of "Range" and therefore, Answer C. is correct.
Answer D. is incorrect because the range does not have anything to do with quotients.(By the way, a quotient is the result of dividing a dividend with a divisor.) The range is only obtainable with subtraction, not division, so answer D. is incorrect.

Find the TWO integers whos product is -12 and whose sum is 1
Answer:
[tex] \rm Numbers = 4 \ and \ -3.[/tex]
Step-by-step explanation:
Given :-
The sum of two numbers is 1 .The product of the nos . is 12 .And we need to find out the numbers. So let us take ,
First number be x Second number be 1-x .According to first condition :-
[tex]\rm\implies 1st \ number * 2nd \ number= -12\\\\\rm\implies x(1-x)=-12\\\\\rm\implies x - x^2=-12\\\\\rm\implies x^2-x-12=0\\\\\rm\implies x^2-4x+3x-12=0\\\\\rm\implies x(x-4)+3(x-4)=0\\\\\rm\implies (x-4)(x+3)=0\\\\\rm\implies\boxed{\red{\rm x = 4 , -3 }}[/tex]
Hence the numbers are 4 and -3
Step-by-step explanation:
[tex]integers \: = x \: and \: y \\ then \: x \times y = - 12 ....(1)\\ x + y = 1.....(2) \\ x = 1 - y.....(3) \\ put \: (3 )\: in \: (1) \\ then \: (1 - y) \times y = - 12 \\ y - {y}^{2} + 12 = 0 \\ {y}^{2} - y - 12 = 0 \\ factorise \\ {y}^{2} - 4y + 3y - 12 = 0 \\ y( y - 4) + 3(y - 4) \\ (y - 4)(y + 3) \\ y = 4 \: and \: - 3 \\ thank \: you[/tex]

Answer:
V = 1716.795 cm³
Step-by-step explanation:
The volume (V) of a cylinder is calculated as
V = πr²h ( r is the radius and h the height )
d = [tex]\frac{1}{3}[/tex] h = [tex]\frac{1}{3}[/tex] × 27 = 9 , then r = 9 ÷ 2 = 4.5 , so
V = 3.14 × 4.5² × 27
= 3.14 × 20.25 × 27
= 1716.795 cm³
Mrs. Delles spent 120$ on a bag that was discounted 25%, what was the original price?
Will give brainiest for right answer.

8, SSS
9, SSA

12. ASA Explanation: A shape is congruent when it's all sides are the same SSS but also the shape's side and angle could also be counted as congruent. it can be like this ASA, SAS, HL, and AAS are a theorem of Congruent but not AA, SS, SSA, AS and AAA this is because They have only two side congruent we don't know the 3rd side. Also SSA is not congruent because we don't know if the unknown side is equal another thing is SSA spelled back word is A## so lets just leave it at that

Find the median, first quartile, third quartile, and interquartile range of the data.
14,25,97,55,66,28,92,38,94
Answer:
Median: 55
First quartile: 26.5
Third quartile: 93
Interquartile range: 66.5
Answer:
55, 26.5, 93, 66.5
Step-by-step explanation:
First put the values in order from least to greatest:
14, 25, 28, 38, 55, 66, 92, 94, 97
The median is the number in the middle of a data set when it's in order from least to greatest. In this case it's 55, because it's in the middle and has 4 values on either side of it.
The first quartile is the median of the values left of the median. There are 4 values, so there won't actually be a middle. So to find the median of the 4 values, find the mean of the middle 2. The median of 14, 25, 28, 38 is 26.5 because it is the mean of 25 and 28.
The third quartile is found the same way but using the values to the right of the median. The median of 66, 92, 94, 97 is 93 because it is the mean of 92 and 94.
The interquartile range is found by subtracting the first quartile from the third. 93 - 26.5 = 66.5
So the interquartile range is 66.5

What is the volume of the figure below, in cubic centimeters?
2 rectangular prisms. One prism has a length of 16 centimeters, width of 6 centimeters, and height of 2 centimeters. The other prism has a length of 15 centimeters, width of 6 centimeters, and height of 30 centimeters.
A.) 2,700
B.) 2,712
C.) 2,892
D.) 3,072
The large cube is representing: 16*16*32= 8192cm
And the small cube is representing: 16*6*2= 72cm
length(cm) × width(cm) × height(cm) = cubic centimeters(cm³)
&
length(mm) × width(mm) × height(mm) ÷ 1000 = cubic centimeters(cm³)
So, answer would be 2,712.
Answer: B
