I'm may not be that good at math, but I'm going to try my best to help you, because I know how it feels to be in this situation!
The first one :
You might be right on D. But I'm thinking B also. The question asks "Which could be a cross section of a rectangular pyramid that has been intersected by a plane perpendicular". But a triangle is basically a flat pyramid.
(I'm typing really fast to help!!!!)
Second one: Its B!! Look at it really closely! You'll get it!!!
(Going really fast now!!!!)
Third one: Between B or D!!! But I think you're right on your choice!!!!
(FASTER FASTER!!!)
FINALLY: Copy and paste your answers into google. People have asked the same question!
I hope I helped. I don't want to make you fail, as I am in the SAME similar situation as you! I really REALLY REALLY HOPE YOU PASS!!!
#1) x-8= -12
#2) 15+k= 2
#3) x/-7= -20
#4) (5/8)(x)= -20
The / in #2 means to divide and the ( ) mean to multiply
The IQR is the range of the box in the box and whisker plot
So if you remember how to do the average of something you are already there
You need 2 numbers
First being the lower quartile and upper quartile
48 is where the lower quartile starts and 70 is where the upper quartile finishes *NEVER USE MEDIAN IN IQR
all you have to do is subtract
70-40 and you get as an answer 22.0 being A as your answer
Do u mean 3x-y=18
If not clear your question and if yes this is the question then the answer is 96.6
Answer: yes it is
