OK so for substitution you will be taking away so say you have 5 apples and someone eats 3 you now have 2 apples. so it would be 5 - 3 =2
I hope this helps
Answer:
144
Step-by-step explanation:
Because area is side times side, and it was a square garden, so that means that there is the same side length on each side so just 12 x 12 is 144.
A linear function means you’re working with a line. Lines can be stated in slope-intercept form: y=mx+b.
To make it a linear function, you simply replace “y” with “f(x)” notation: f(x) = mx + b
The information you gave told you m=2 and b=6, since (0,b) is the y-intercept.
Putting that all together you have:
f(x) = 2x + 6
Answer:
the probability that the satellite fails is 0.0124
Step-by-step explanation:
The manufacturer of the satellite defines a success as a firing in which the satellite comes within 10 feet of the target.
This means that success has the 
standard deviations range in the error distribution.
Z-scores of the Ranges not within -2.5 and 2.5 can be considered as fail and the probability of this is:
P(z>2.5) + P(z<-2.5) = 2 × P(z>2.5) = 2 × 0.0062 = 0.0124
