The answer is four because 2 x 0 is 0 and then 12 divided by 3 is for
THE ANSWER IS 4
Answer:
and 
Step-by-step explanation:
Recall that
is a value of the function cosine for the special angles:
and
, then:

Step-by-step explanation:
(a)
the probability of parcels weighing 35oz or less is
0.841
the probability of parcels weighing 14oz or less is
0.023
the probability of parcels weighing between 14 and 35oz is the probabilty of 35oz minus the probability of 14oz
0.841 - 0.023 = 0.818
the percentage is the probability × 100 = 81.8%
(b)
the probability of parcels weighing more than 49oz is 1 minus the probability to weigh less than 49oz.
the probability to weigh less than 49oz is
0.99865
so, the probability to weigh more than 49oz is
1 - 0.99865 = 0.00135
the percentage is again probability×100 = 0.14%
HERE IS YOUR ANSWER HOOMAN:
8
STEP BY STEP EXPLANATION FAM:
We have a set of four numbers and the mean is 5. We can see that the sum of the values is 20:
=5
We have another set of three numbers whose mean is 12. We can write that as:
=12
To find the mean of the seven numbers together, we can add the values together and divide by 7:
=
=8
