Answer:
2/5
Step-by-step explanation:
The experimental probability is
P (heads) = number of heads/ total tosses
= 8/20
= 2/5
Answer:
Mean of the data would be 6c
Step-by-step explanation:
<u>Rule to Remember:</u> Whenever each term of the data is multiplied by the same number, the new mean is previous mean multiplied by that number.
In this case, original value of mean was c. Each value of the data is multiplied with 6 so a result the new mean would be 6 times the original mean i.e. 6c
Let us consider that original values in the data set are x, y and z. Their mean would be:

If each value of the data is multiplied with 6, the new values would be 6x, 6y and 6z. The mean in this case will be:

We can see from above that the new mean is 6 multiplied to the original mean.
Therefore, the answer to this question is 6c.

All of the statements has the qualifier "can be".
This means that we need just one single in each example to make the statement true.
In an equilateral triangle, medians, angle bisectors, altitudes and perpendicular bisectors are all coincident, which makes the first three statements true. This in turn makes the fourth statement true.
So there are no false statements.
Divide it by 2, since you can make it into a half.
