Answer:
We can make an equation
So we can make “x” the price PER stop
And we can make ”y” the initial fee
3x + y = 6.5
7x + y = 12.5
11x + y = 18.5
We’re trying to find price per stop.
So we can calculate the difference between Each.
So for 3 and 7 stops, theres 4 stops in between
12.5-6.5= 6
6 dollars difference.
4 stops in between
So we can do
6/4= 1.25
Each stop is $1.25
We can doublue check this…
So 1.25 for each stop fo for the first one
1.25*3= 3.75
ANd the initial fee (from subtraction) 2.75
SO using this
7*1.25= 8.75
Plus the initial fee which is 2.75
you’d get the same price.
Final answer:
Each stop is $1.25
Initial fee is $2.75

Answer: 0.5467
Step-by-step explanation:
We assume that the test scores for adults are normally distributed with
Mean :
Standard deviation :
Sample size : = 50
Let x be the random variable that represents the IQ test scores for adults.
Z-score :
For x =85
For x =115
By using standard normal distribution table , the probability the mean of the sample is between 95 and 105 :-
Hence, the probability that a randomly selected adult has an IQ between 85 and 115 =0.5467
Answer:
<em>x</em> = 1/5
