Answer:
Interquartile Range = 71
Step-by-step explanation:
The interquartile range is the middle 50% of the data set. First you calculate the location of the 3rd quartile (75% of the data set) by computing:
LQ3 = (75/100)(n + 1) -> here n is the number of observations you have, so 15. You can now compute LQ3 = (75/100)(16) = 12
The data at location 12 of your data set is 170.
Now you compute the 1st quartile (25% of the data set):
LQ1 = (25/100)(16) = 4
The data at location 4 of your data set is 99.
The difference between the 3rd quartile (170) and the 1st quartile (99) is your interquartile range:
IQR = 170 - 99 = 71
Did I do this right?
If not can you tell me what I did wrong?

Sofia's family took a road trip to Mount Rushmore. Sofia slept through the last 65% of the trip. If the total length of the trip was 840 miles, how many miles had they travelled when Sofia fell asleep?
Answer:
546
Step-by-step explanation:
Sofia slept 546 miles and was awake for 45% which is 294 of the miles.
You can find this by finding 1%, and that would be 8.4. (You get 1% from dividing 100 from the 100% number.) Then you multiply it by 65 so now you get 546.
If the total length of the trip was 840 miles, then Sofia had traveled 294 miles before she fell asleep.
Given that,
If Sofia slept through the last 65% of the trip and the total length of the trip was 840 miles,
then she stayed awake for the first 100% - 65% = 35% of the trip.
Here, we have to calculate the distance she traveled before falling asleep, we can use the percentage of the total distance:
Distance traveled by Sofia = 35% of 840 miles
Distance traveled by Sofia = 0.35 * 840
Distance traveled by Sofia = 294 miles
So, Sofia had traveled 294 miles before she fell asleep.

A bag contains tiles of different colors. Roshan randomly selects a tile from the bag and returns the tile to the bag after recording the color. He picks a green tile 6 times, a red tile 20 times, a blue tile 7 times, a purple tile 8 times, and a black tile 4 times. Based on the results, what is the theoretical probability that the next tile Roshan picks will be green?
Answer:
6/41
Step-by-step explanation:
6 + 7 + 20 + 8 = 41 so that is number of tiles he took. 6 of those were 41 so therefore, the chance is 6/41
Answer:
There are four red marbles and six blue marbles in all, for a total of ten marbles.
Without replacement, the probability of the first marble being blue is 6/10, while the probability of the second marble being red is 4/9.
The probability of both events occurring is reduced to 4/15 by multiplying 6/10 * 4/9 = 24/90.

A) Vertical angles
B) Complementary angles
C) Supplementary angles
D) None of the above
Answer:
D) None of the above
Step-by-step explanation:
Let's use process of elimination!
A) Vertical angles are opposite angles formed by two intersecting lines. These two are adjacent, therefore rendering this statement false.
B) Complementary angles are two adjacent angles that add up to 90 degrees. There is no proof that m∠a+∠b=90°, therefore this statement is false.
C) Supplementary angles are two adjacent angles that add up to 180 degrees. Assuming A∈ED, this statement is false as well.
D) None of the answers above are correct.

Quickly help please!!! An angle measures 162° more than the measure of its supplementary angle. What is the measure of each angle?
Answer:
Your answer is 18 ° and 162 °
Step-by-step explanation:
All you need to do is subtract the number you're given from 180.
Answer:
9 and 171 degrees
Step-by-step explanation:
Let the first unknown angle be x. Then the second is x + 162 degrees. Then, since supplementary angles sum up to 180 degrees,
x + x + 162 degrees = 180 degrees, or
2x = 18 degrees. Therefore the first angle is 9 degrees and the second is 171 degrees.

We know that the circles diameter is 15 mm. We can tell that by looking at the side of the rectangle. It says 15 mm.
Either way, we use the formula to find the area of a circle:
A = [tex]\pi[/tex]d

A = 47.1
The area of the circle is 47.1. (i think?)

Due to gravity, an object falls 16t squared feet in t seconds. You drop a backpack from a window that is 60 feet above the ground. Will the backpack hit the ground in 2 seconds?
Answer:
No
Step-by-step explanation:
Since gravity falls at a rate of 16 feet per second, t= number of seconds.
if t=2 seconds, you would have the equation 16*2 = fall amount
16*2 =32. Since it is less than 60 feet, the backpack won't hit the ground in 2 seconds

Hope this helps!
All the correct methods to interpret fractions is,
Fractions as parts of wholes or parts of sets;
Fractions as the result of dividing two numbers;
Fractions as the ratio of two quantities;
Fractions as operators; and fractions as measures.
What is mean by Fraction?A fraction is a part of whole number, and a way to split up a number into equal parts. Or, A number which is expressed as a quotient is called fraction. It can be written as the form of p : q, which is equivalent to p / q.
