Answer:
APart 1:
A.53 =53
B.3^5/3^-6 =177147
C.(1/4)^3 • (1/4)^2 = 1 /1024
D.(-7)^5/(-7)^7 = 1/49
Step-by-step explanation:
I tried my best for part 2 but i'm pretty sure it's not right. I think 1/1024 and 1/49 has a value between 0 and 1
The interquartile range (IQR) is 20
You find this by subtracting the values of Q3 and Q1
Q3 is the right most edge of the box which is 45
Q1 is the left most edge of the box which is 25
IQR = Q3 - Q1 = 45 - 25 = 20
Side Note: The median is not 45. The median is actually 40 since this is the middle line of the box, which is in between 35 and 45
Assuming that you mean to put n instead of 5, this is demonstrating The Identity Property.
The identity property is the property that states that by adding 0 to a number, you don't change the value. For example, 510 + 0 = 510.
The sum of two numbers if just the numbers added together, so you would just need to do some simple algebra.
The ages added together are 68, and the opposite of addition is subtraction!
(total age) - (sarahs age) = (mothers age)
68 - 24 = 44
44 should be her mothers age!
(If you were trying to calculate the sum of their ages, you would just add them together, and 24 + 44 = 68)
∠СXA = ∠BXA + ∠СXB = 30°20' + 40°35' = 70°55'
