Answer is 3x because u do 12-9 which gets three and since it was originally 12x and you don’t know what X is you just put the x on the 3 and get 3x
Length = 120+20
width = 120
answer:
length=140
width=120
check:
140x2=280
120x2=240
280+240=520
Answer:
True mean/population mean
Step-by-step explanation:
The standard error in this case gives an estimate on how far the values observed during the course of the experiment ate likely to be from the true mean/population mean.
Answer:
C. 98.0%
Step-by-step explanation:
If t represents 35 days, then in order to find the daily decay rate we will have to input 1/35 as the value of t.
100(0.5)^
= 98.039
The daily decay rate is 98.0%
If it has to be perpedicular to y = x, then the slope has to be -1/x because perpedicular slope is the opposite reciprocal. Now plug what you know into the point slope formula.
y - 2 = -1/1 (x - 4)
***** Since -1/1 is the same as -1, it can be rewritten as -1. ****************
y - 2 = -1 (x - 4)
Now distribute -1 times x and -4.
y - 2 = -x + 4
Add 2 to both sides to get y by itself.
y = -x + 2
Your answer should be:
y = -x + 2
