If the divisor is greater than the dividen then you know that the answer is going to be more than one. But if the divisor is smaller than the dividen then you know that the answer is going to be less than one like a decimal.
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
10 us cups, the formula is to divide the volume value by 8.
Answer:
x=2 y=0
Step-by-step explanation:
y=4-2x
3x-2y=6
3x-8+4x=6
7x-8=6
7x=14
x=2
y=4-4
y=0
x = # of weeks
y = total amount of money
Your savings account: $122 + $12x = y
Your friend's savings account: $92 + $17x = y
As the question suggests, we need to set both equations equal to each other.
$122 + $12x = $92 + $17x
Subtract $92 from both sides and subtract $12x from both sides.
$30 = $5x
Divide both sides by $5
6 = x
It will take 6 weeks for you and your friend to have the same balance.
