The question is incomplete. The compete question is :
Saul decides to use the IQR to measure the spread of data. Saul calculates the IQR of the data set to be 27. Saul asks Jasmine to check his work. Saul copies the data in numerical order from least to greatest for Jasmine. 25, 30, 50, 50, 50, 50, 56, n, 250. What is the value of n that will make the IQR of the data set equal to 27?
Solution :
The inter quartile range is being measured as : 3rd quartile - 1st quartile
The 1st quartile = 25% mark
The 3rd quartile = 75% mark
The data set as given in the question is :
25, 30, 50, 50, 50, 50, 56, n, 250
Therefore, the total number of the sample = 9
And the median is = 50
The median separates the given data sets into two equal halves-- that is the upper half and the lower half.
Let the middle of a lower half is the 1st quartile be [tex]$Q_1$[/tex]
And the middle of a 2nd half is the 3rd quartile be [tex]$Q_3$[/tex]
∴ [tex]$Q_1=\frac{30+50}{2}$[/tex]
[tex]$=40$[/tex]
[tex]$Q_3=\frac{56+n}{2}$[/tex]
Now for the IQR of the data set to be equal to [tex]$27$[/tex],
[tex]$\frac{56+n}{2}-40=27$[/tex]
[tex]$\frac{56+n}{2}=27+40$[/tex]
[tex]$\frac{56+n}{2}=67$[/tex]
[tex]$56 +n=134$[/tex]
[tex]$n=134-56$[/tex]
[tex]$n=78$[/tex]

A grocery store collected sales data. It found that when customers buy less bread, they tend to purchase more rice. What can we conclude?
A. There is no correlation between amount of bread bought and amount of rice purchased.
B. There is a correlation between amount of bread bought and amount of rice purchased. However, there is no causation. This is because there is an increase in the amount of rice purchased with a decrease in the amount of bread bought.
C. There is a correlation between amount of bread bought and amount of rice purchased. There may or may not be causation. Further studies would have to be done to determine this.
Answer: C
Step-by-step explanation: C because there is obviously a correlation yet we cannot determine if there is causation or not.

Find the eighth term of a geometric sequence for which a,3 = 35 and r= 7.
Answer:
588245.
Step-by-step explanation:
nth term = an = a1 r^(n-1) where a1 = the first term
a3 = 35 = a1 7^(3 - 1)
35 = a1* 49
a1 = 35/49 = 5/7
So the 8th term = (5/7)* (7)^7
= 588245

A spinner has 10 congruent sections labeled with colors as shown. If the spinner is spun twice, what is the probability that the first spin will land on
yellow and the second spin will land on green?
The congruent 10 - labeled color spinner isn't attached and could not be found.
However, we could solve the problem hypothetically.
Answer:
Kindly check explanation
Step-by-step explanation:
The events here are independent events :
Probability = required outcome / Total possible outcomes
Total possible outcomes = number of divisions on spinner = 10
Required outcome = number of specified color
Therefore, Probability that first spin lands on yellow :
Number of yellow divisions on spinner / total number of divisions
Let number of yellow divisions = 3
Therefore. Probability that first spin lands in yellow = 3 / 10
Probability that second spin lands on green :
Number of green divisions on spinner / total number of divisions
Let number of green divisions = 2
Therefore. Probability that first spin lands on green = 2 / 10
P(first) * P(second)
3/10 * 2/10 = 3/10 * 1/5 = 3/50
Recall ; this is an hypothetical situation and not the original problem.
The probability that the first spin will land on yellow and the second spin will land on green is; 2/5
Conditional Probability Problem
The spinner is missing but from online search, it is discovered that from the 10 congruent sections labeled, the colors are as follows;
Yellow - 2 sections
Green - 2 sections
Red - 3 sections
Blue - 3 sections
Thus, probability of getting yellow on first spin is;
P(yellow on first spin) = 2/10
Probability of getting green on second spin is;
P(green on second spin) = 2/10
Thus, probability that the first spin will land on yellow and the second spin will land on green is;
P(1st on yellow and 2nd on green) = 2/10 + 2/10
P(1st on yellow and 2nd on green) = 2/5

Which is NOT true?
A 9 + 4 = 17 - 4
B 8 + 7 = 14 + 3
C 11 = 19 - 8
D 5 + 8 = 20 - 7
Answer:
B is not true
Step-by-step explanation:
8+7= 15 and 14+3= 17
15 is not equal to 17
Answer:
B is the one equation that is NOT true.
Step-by-step explanation:
A: 9+4 is 13, and 17-4 is 13 as well. This equation is true, 13=13.
B: 8+7 is 15, and 14+3 is 17. This equation is false, because 15 is not equal to 17. Although we have our answer, we need to still check the other equations.
C: 11 is, well, 11, because nothing changed on that side of the equation. 19-8 is 11, so this is true because 11=11.
D: 5+8 is 13, and 20-7 is 13. This equation is also true, because 13=13.
The only equation that is not true, is B. (8+7 = 14+3)
What is AB?
Triangle ACB is right angle triangle. The length of AC is 12 and BC is 35.
Answer:
the answer is 35
Step-by-step explanation:
because if BC is 35 that means AB will have to be that same because it's a triangle
The required value of AB is 33 units for the given right triangle.
What is the right triangle?A right triangle is defined as a triangle in which one angle is a right angle or two sides are perpendicular.
Triangle ACB is a right-angle triangle. The length of AC is 12 and BC is 35.
Pythagoras's theorem states that in a right-angled triangle, the square of one side is equal to the sum of the squares of the other two sides.
Assume BC is the hypotenuse,
Since this is a right triangle, use the formula AB² + AC² = BC² and substitute values of AC = 12 and BC = 35.
AB² + AC² = BC²
AB² + (12)² = (35)²
AB² + 144 = 1225
AB² = 1225 -144
AB² = 1081
AB = 32.8785
Rounded to two decimal places,
AB = 33 units
Therefore, the required value of AB is 33 units.

Write a simplified polynomial expression that can be used to represent the perimeter of the rectangle. 3x-7 and x-7
Answer:
P = 8x-28
Step-by-step explanation:
Given that,
Length = (3x-7)
Width = (x-7)
We need to find the perimeter of the rectangle. The formula for the perimeter of a rectangle is given by :
[tex]P=2 (l+b)\\\\P=2(3x-7+x-7)\\\\P=2(4x-14)\\\\P=8x-28[/tex]
So, the perimeter of the rectangle is equal to 8x-28.
Some trapezoid has an area of 213.86 yd2 and a height of 18 yd. If one of the bases measures 5 yd, then the other base must measure ___ yd.
Answer:
The other base measure 18.76 yd.
Step-by-step explanation:
A = h ((a+b) / 2)
213.86 = 18 ((5 + b) /2)
(5 + b) /2 = 11.88
5 + b = 23.76
b = 18.76 yd

Which of the following statements is not true if f(x) = 2x2 + x – 3 and g(x) = 2x3 + 3x2 – 2x – 3?
Answer:
Option 3 is not true for f(x) and g(x).
The incorrect statement will be;
⇒ f (x) × g(x) = 4x⁵ + 8x⁴ - 13x³ - 17x² + 3x + 9
What is Division method?Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications. For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.
Given that;
The function are,
⇒ f(x) = 2x² + x - 3
And , g(x) = 2x³ + 3x² - 2x - 3
Now,
Since, The function are,
⇒ f(x) = 2x² + x - 3
And , g(x) = 2x³ + 3x² - 2x - 3
Hence, We get;
⇒ f (x) + g(x) = 2x² + x - 3 + 2x³ + 3x² - 2x - 3
= 2x³ + 5x² - x - 6
⇒ g (x) - f (x) = (2x³ + 3x² - 2x - 3) - (2x² + x - 3)
= 2x³ + 3x² - 2x - 3 - 2x² - x + 3
= 2x³ + x² - 3x
⇒ f (x) × g(x) = (2x² + x - 3) (2x³ + 3x² - 2x - 3)
= 4x⁵ + 6x⁴ - 4x³ - 6x² + 2x⁴ + 3x³ - 2x² - 3x - 6x³ - 9x² + 6x +9
= 4x⁵ + 8x⁴ - 7x³ - 17x² + 3x + 9
Thus, The incorrect statement is,
⇒ f (x) × g(x) = 4x⁵ + 8x⁴ - 13x³ - 17x² + 3x + 9
