He will never reach the full foot, this is because if he travels 1/2 of the distance of the previous jump each time there will always be a fraction that is unaccounted for.
Part a: For variable X using z score you have (x-30)/10, replace X for this expression in (a), i mean Z=2+10((x-30)/10) = 2+x-30= put this in the way of z score = (x-18)/1, so the mean is 18 and standard deviation is 1.
Part b: Z=X+Y= (x-30)/10 + (x-20)/8 = solve adding fractions = (18x-440)/80 now divide all the numbers between 18 (because you need to show as z score way) = (x-24.4)/4.4, so the mean is 24.4 and standard deviation is 4.4.
For part c,do the same.
Answer:
Step-by-step explanation:
X+2x-5= 40
3x-5=40
+5=+5
3x=45
3x/3=45/3
X=15
Answer:
The answer is B lol
Step-by-step explanation:
1. Yes because the vertical line intersects the graph in one or less points.
2. No because the inputs repeat (4).
