Answer:
(4.5, 0.3125)
Step-by-step explanation:
given that
The mean is 4.5 inches
the standard deviation is 1.25 inches
and, the sample of 16 rabbits is selected
we need to find out the approximate distribution
so,
= (4.5, 1.25 ÷√16)
= (4.5, 0.3125)
hence, the same is to be considered
Which function has an inverse that is also a function? a {(–1, 3), (0, 4), (1, 14), (5, 6), (7, 2)} b {(–1, 2), (0, 4), (1, 5),

An expression, that is a function, will have no x-repeats on the x,y pairs.
and expression that is a function, and has an inverse that is also a function, will have no x-repeats, and no y-repeats either, so the pairs will be unique for the set, let's do some checking then,
Answer:
x...third number
4x...second number
x-9...first number
(x)+(4x)+(x-9)=141
x+4x+x-9=141
6x-9=141
Let's add 9 to both sides...
9+6x-9=141+9
6x=150
Let's divide both sides by 6...
(6x)/6=150/6
x=25
third number...25
second number...(4)(25)=100
first number...(25-9)=16
Let's check our work...
25+100+16=141
141=141
<span>1 . (–2, –3) and (–4, 4)
d = </span>√(-4 - -2)^2 + ( 4 - -3)^2
d = √85<span>
2.Find the distance EA for the points E(–8, –2) and A(4, 1).
</span>d = √(4 - -8)^2 + ( 1 - -2)^2
d = 3√17<span>
3.Find the distance EA for the points E(2, 3) and A(4, 2).
</span>d = √(4 - 2)^2 + ( 2 - 3)^2
d = √5<span>
4. Find the distance between (0, 0) and (5, 8).
</span>d = √(5 - 0)^2 + ( 8 -0)^2
d = √89
<span>At
top speed, a rabbit can cover 7 miles in 12 minutes.
Let’s solve for the unit rate:
=> 7 miles in 12 minutes. Let’s solve for the miles per minute value
=> 7 / 12 = 0.58 miles per minute
If a rabbit could continue at this rate
indefinitely, how long would it take the rabbit to cross the 220-mile expanse
of the Mojave Desert.
=> 220 miles / 0.58 miles/minute = 379 minute
Thus, it will take a rabbit a 379 minute to finish 220 miles.</span>
