Answer:
16x5+6x4
Step-by-step explanation:
(2x(3+5)+6)(x4)
=(2x(3+5)+6)(x4)
=(2x(3+5))(x4)+(6)(x4)
=16x5+6x4
distance = speed * time
the first bus speed = x
second bus = x - 12
the sum of distance = 765 miles
first distance = 6x
second distance = 6 (x -12)
6x + 6(x-12) = 765
x + x -12 = 127.5
2x = 139.5
x = 69.75 mi/h which is the faster bus
the second bus speed = 57.75 mi/h

Answer:
<em>"The true mean weight of the geese is less than or equal to 40 pounds"</em>
<em></em>
Step-by-step explanation:
<u>Something (or some value) can be either equal to, greater than, or less than another thing (another value).</u>
Null Hypothesis is what is given and Alternate is what we are testing.
Since Null Hypothesis is given that the mean weight is GREATER THAN 40 pounds, the ALTERNATE HYPOTHESIS would be the mean weight is either EQUAL TO or LESS THAN 40 pounds.
Thus, alternate hypothesis is <em>"The true mean weight of the geese is less than or equal to 40 pounds"</em>
He held his breath 12 minutes and 47 seconds, which means that he was 47 seconds over 12 minutes.
So, the question is: how many milliseconds are 47 seconds?
By definition, one second is 1000 milliseconds, so 47 seconds are 47000 milliseconds.
