Answer:
B)13 pints
Step-by-step explanation:
SO first we find the unit rate
We know that in 90 minutes (hour and a half), the water leaked 6 pints form 2;30 to 4
Now So we can divide to find unit rate
6/90=1/15
So 1 pint for every 15 minutes
And now we want to know the amount it takes from 2:30 to 6:30 which is 4 hours
40 hours is 240 minutes
SO we can divide now
240/15=16
SO 16 pints leaked but the question asked for remaining water in container
So 29-16 is 13
So B)13
Find the distance of each trip:
68 km / 34 trips = 2 km per trip
Divide total distance by distance per trip:
348 km / 2 km per trip = 174 trips
Answer: 174 trips
Answer:
Best predicted value of y' = 86.16 kg
Step-by-step explanation:
Given,
n = 100
Range of heights = 138 - 190cm
Range of weight = 39 to 150 kg
x' =167.46 cm
y' = 81.44 kg
r = 0.108
p value = 0.285
y = - 105 + 1.08x
Significance level = 0.05
We reject H0 since pvalue, 0.285 is less than significance level of 0.05.
Therefore,
Given height of adult male, x = 177 cm
y = - 105 + 1.08x
The best predicted value of y' =
y' = - 105 + 1.08(177)
y' = 86.16 kg
The best predicted value of y' is 86.16kg
