The range is the difference between the highest and lowest values in a set of numbers. To find it, subtract the lowest number in the distribution from the highest.
7+10x-2x-2=-3
—-Combine like terms...10x-2x=8x and 7-2=5
8x+5=-3
——subtract 5 on both sides.. the 5’s will cancel each other and -3-5=-8
8x=-8
——Divide 8 on both sides...the 8’s will cancel out and -8 divided by 8 = -1
Answer: x = -1
Length of line RS is probably 20 because it’s not smaller than the line it’s parallel to but it’s not equal either so the answer has to be c unless there’s a d that’s between 10-20
F(t)=262(1.6)^t
Initially the tundra has: f(0)=?
t=0→f(0)=262(1.6)^0
f(0)=262(1)
f(0)=262 caribou
Answer:
Initially, the tundra has 262 caribou, and every 1 year, the number of caribou increases by a factor of 1.6
93% you have to divide the $120 by $12 and then multiply what you get by $12
