Answer:
Part A
30
44
26
Part B
176
Step-by-step explanation:
Total: 65+110+75 = 250
P(O) = 75/250 × 100 = 30%
P(A) = 110/250 × 100 = 44%
P(K) = 65/250 × 100 = 26%
Apple juice:
44% of 400
44/100 × 400
176
Answer:

We have to find the angle BDC.
In triangle ABC
Sum of interior angles of triangle=180 degrees






Angles subtended on the same are ac are equal.

Answer:

In order to find the variance and deviation we need to find the mean with this formula:

And replacing we got:

Now we can find the variance with the following formula:

And replacing we got:

And the standard deviation would be:

For this case since the range observed is large is better to use a measure of variation in order to check the spread of the values and take a decision useful
Step-by-step explanation:
For this case we have the following dataset:
60 58 55 53 47 45 44 43 25 25 20 18 7 5
We can find the range with this formula:

And replacing we got:

In order to find the variance and deviation we need to find the mean with this formula:
