Answer:
19 gallons
Step-by-step explanation:
We divide the total distance by the distance per gallon: 656/35. We get 18.74..., so Jon would need 19 gallons to travel 656 miles.
What is the price per ounce, rounded to the nearest cent? $0.29.
Answer:
about 26 min
Step-by-step explanation:
Toni rows a boat 4.5 km/h upstream and then turns around and rows 5.5 km/h back downstream to her starting point
First we find the average speed
We add both speed and divide it by 2

Now we find the distance for round trip
given total time is 48 mins. convert mins into hours
48 mins = 48 divide by 60 = 0.8
average speed = 5 km/hr
Distance = speed * time = 5 * 0.8 = 4 km
distance covered both ways = 4 km
so 4 divide by 2 = 2 km each way
To find time taken for upstream = distance of each way / speed of upstream
time = 
Now convert hours into minutes
0.44* 60= 26.4 minutes
Answer:
C
Step-by-step explanation:
In the table, we are given the points [ (-3, -5), (2, y), (5, 11), (8, 17) ]
We are given the equation [ f(x) = 2x + 1 ] where 2 = slope and 1 = y intercept.
We need to find the value of "y".
y2-y1/x2-x1
y-(-5)/2-(-3) = 2
y+5/5 = 2
y = 5
Best of Luck!
Answer:


So then we can conclude that we expect the middle 95% of the values within 18 and 30 minutes for this case
Step-by-step explanation:
For this case we can define the random variable X as the amount of time it takes her to arrive to work and we know that the distribution for X is given by:

And we want to use the empirical rule to estimate the middle 95% of her commute times. And the empirical rule states that we have 68% of the values within one deviation from the mean, 95% of the values within two deviations from the mean and 99.7 % of the values within 3 deviations from the mean. And we can find the limits on this way:


So then we can conclude that we expect the middle 95% of the values within 18 and 30 minutes for this case
