Answer:
Step-by-step explanation:
Since; the density function diagrams were not included in the question; we will be unable to determine the best which depicts this problem.
However;
Let use X to represent the time required for the delivery.
Then X~N(3.8 ,0.8)
i.e
E(x) = 3.8
s.d(x) = 0.8
NOW; P(x>4) = P(X-3.8/0.8 > 4-3.8/0.8)
= P(Z > 0.25)
= 1-P(Z < 0.25)
=1 - Φ (0.25)
= 1 - 0.5987 ( from Normal table Φ (0.25) = 0.5987 )
= 0.4013
Thus; the probability a single delivery would take more than 4 hours is 0.4013
What is the z value corresponding to the interval boundary?
The z value is calculated as:
z = 0.25
Answer:
7X
Step-by-step explanation:
4X -6+ 3X +6
Combine like terms
4X + 3X -6 +6
7X +0
7X
we know that
<u>Applying the Pythagorean Theorem</u>
solve for HJ
in this problem we have
Substitute the values in the formula above
therefore
<u>the answer is the option</u>
B. 5 sq. root 3 units
Answer:
With approximately a half-ounce of aluminum per can, or 32 cans per pound, that makes each one worth about 1.7 cents. Although there are some people making a living collecting cans in the streets, it isn't a good living.

Answer:
two ten-thousandths
Step-by-step explanation:
You would write 0.0002 as two ten-thousandths. However some people say it the easy way, zero point zero zero zero two.
Hope this helps!
