Answer:
4 hours
Step-by-step explanation:
Cost of renting a bike at Oceanside Bike Rental Shop = 18 + 8x
Where,
x = number of hours for renting the bike
Alyssa paid 50 dollars to rent a bike.
How many hours did she pay to have the bike checked out ?
C = 18 + 8x
50 = 18 + 8x
Subtract 18 from both sides
50 - 18 = 18 + 8x - 18
32 = 8x
Divide both sides by 8
32 / 8 = 8x / 8
4 = x
x = 4 hours
Answer:
0.5161
Step-by-step explanation:
There is a lot of unnecessary information in this question. We only need info for Smartphone A users since our sample size consists of entirely Smartphone A users, and it's asking about them. So ignore any info that isn't about Smartphone A users.
We have (for Smartphone A users):
x = 15, s = 6.4, n = 16
We want: P(14.5 < x < 17)
We need to find the z-scores for the values of 14.5 and 17 using the data for smartphone a users.
See attached photo for the calculation of the 2 z-scores and the probabilities
Its 17 15 and 8 i just did that on a test as well
srry no explanation :(

Answer:
Take the square root of the constant (number w/o the variable) and then multiply that by 2.
Step-by-step explanation:
A perfect square trinomial is something like this: If I have 6x, and I want to find the last term I would take half a six and then square it to get 9.
SO.... To get the middle term of a perfect square trinomial, you would need to do the reverse.. So...
1) Take the square root of the constant...
2) Multiply that by 2
