The longest spin of a basketball on one finger is 255 minutes or 4.25 hours.
Step-by-step explanation:
the longest spin of a basketball on one finger is 255 minutes.
We need to find how many hours is that.
So, we need to convert 255 minutes into hours.
We know that,
60 minutes = 1 hour
Using Unitary method:
60 minutes = 1 hour
1 minute = 1/60 hour
255 minutes = 1/60 * 255 hour
255 minutes = 255/60 hour = 4.25 hour
255 minutes is 4.25 hour.
So, The longest spin of a basketball on one finger is 255 minutes or 4.25 hours.

The square root of 3 is irrational
Answer:
0.86
Step-by-step explanation:
The z-score we need to make the comparison is given by
where
= the standard deviation established in the study
n = the sample size
and for the Normal distribution N(0,1) we want to find
<em>P(X > -1.0801)
</em>
By using a spreadsheet or the table attached, we find that
P(X > -1.0801) = 0.86
(See picture attached)
We can create two equations here:
(1) Volume = area of square * height of box
85.75 = s^2 h
(2) Cost = 3 * area of square + 1.5 * area of side box
C = 3 s^2 + 1.5 s h
From (1), we get:
h = 85.75 / s^2
Combining this with (2):
C = 3 s^2 + 1.5 s (85.75 / s^2)
C = 3 s^2 + 128.625 s-
Taking the 1st derivative and equating dC/ds =
0:
dC/ds = 6s – 128.625 / s^2 = 0
Multiply all by s^2:
6s^3 – 128.625 = 0
6s^3 = 128.625
s = 2.78 cm
So h is:
h = 85.75 / s^2 = 85.75 / (2.78)^2
h = 11.10 cm
So the dimensions are 2.78 cm x 2.78 cm x 11.10 cm
The total cost now is:
C = 3 (2.78)^2 + 1.5 (2.78) (11.10)
C = $69.47
Answer:
b. 0.09
Step-by-step explanation:
0.09 is the only one smaller than 0.59
0.59>0.09
