Answer:
70th percentile for the amount of time between customers entering is 30.10
Step-by-step explanation:
given data
mean = 25
to find out
What is the 70th percentile for the amount of time between customers entering Clay's store
solution
we know that here mean is
mean = ..................1
so here 25 =
and we consider time value corresponding to 70th percentile = x
so we can say
P(X < x) = 1 -
P(X < x) = 70 %
1 - = 70 %
1 - = 0.70
= 0.30
take ln both side
= ln 0.30
= 1.203973
x = 30.10
70th percentile for the amount of time between customers entering is 30.10
Sorry bro I won't do it again
The driver has to drive 20 miles to come back to the starting point directly
Step-by-step explanation:
The driver has driven in the form of two legs on a right-angled triangle where the vertical side (perpendicular) is 12 miles and the horizontal side (base) is 16 miles.
Now as the driver has to return back to the starting point directly, it will form a right-angled triangle making the direct path a hypotenuse
So,
B = 16
P = 12
H = ?
we have to find the hypotenuse
As the triangle is a right angled triangle, we can use the Pythagoras theorem to find the length of hypotenuse So,
taking Square root on both sides
So
The driver has to drive 20 miles to come back to the starting point directly
