Answer:
p=4CP - 26
C= p/4P + 13/2P
P= P/4C +13/2C

Answer:
The Inter Quartile Range is 20.
Step-by-step explanation:
The interquartile range is Q3 - Q1. So first let's find the median (Q2) so we can find Q1 and Q3. Since there is an even amount of numbers, we need to find the average of the middle to numbers. My work is in the attached image.
If this helps, I would appreciate it if you gave me brainliest :)
Answer:
-4/3
Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable
Answer:
52
Step-by-step explanation:
S(blue) = S(Whole) - S(cut part)
S(blue) = 7*11 - 5*5 = 77 - 25 = 52
Use the sine theorem:
sin(angle A) / length of side a = sin (angle B) / lenght of side b
Here:
angle A = 32°
length of side a = length from school to library = x
angle B = 110°
length of side b = 2.2 mi
Then, sin(32°) / x = sin(110°) / 2.2 mi
=> x = 2.2 mi * sin (32) / sin (110)
x = 1.24 mi
Therefore the answer is the option B. 1.2 mi
