Answer:
Step-by-step explanation:
ok. you said 2000 and 2500 so I'll just solve for both.
this is very simple, mis/mia wants to earn 2000/2500 so let's solve
this can be done two ways. an equation way, or a dividing way. I personally like the dividing way.
2000 divided by 55= 36.36-- so she will have to tune up 37 bicycles
2500 divided by 55= 45.45-- so she will have to tune 46 bicycles. this is because 46 bicycles, times the amount of money == just a little over 2500 so she has reached her goal

Answer:
a) Function
b) Not a function
c) Function
d) Not a function
Step-by-step explanation:
a) Domain = { 7,-6,2}
Range = {5,0,3}
It is a function as every value in domain has some and unique value mapped to it in Range
b)
Domain = { 7,-6,2}
Range = {5,0,-2,3}
It is not a function as -6 value in domain has two values mapped to it in Range
c)
Domain = { 7,2}
Range = {-6,-7}
It is a function as every value in domain has some and unique value mapped to it in Range
d)
Domain = { 7,-6}
Range = {5,0,3}
It is not a function as 7 value in domain has two values 3 and 5 mapped to it in Range
For the answer to the question above,
<span>Sample mean is given by,
x = (1/n)∑x˅i .... ˅ means sub
x = (1/5)(60 + 40 + 35 + 45 + 39)
= 43.8
z-score is given by,
z = (X - μ)/σ .... μ is population mean, σ is the standard deviation
z = (43.8 - 43.8)/8.7
= 0
</span>so the answer is zero
I hope my answer helped you.
Answer:
The correct option is:
1/81
Step-by-step explanation:
The given expression to us is:
(3²)⁻²
In this expression, the two powers, which are 2 and -2, are multiplying with each other, we can write it as:
(3)⁻⁴
Now we know that a negative power of a number can be converted into a positive power one if we take reciprocal of the given number.
It can be written as:
(1/3)⁴
Further simplify the expression:
1/81
Thus the correct choice from the given options is:
1 over 81 or 1/81
