Answer:
1.1833 to 4 places of decimals.
Step-by-step explanation:
The general formula for change of base is
log_a x = log_b x / log_b a
So
log_7 10 = log_10 10 / log_10 7
= 1/ 0.845098
= 1.1833.
Considering the concepts of the mean and the median of a distribution, the distribution of dates would be skewed to the left because the <u>mean would be less than the median</u>.
<h3>What are the mean and the median of a distribution?</h3>
- The mean of a data-set is given by the <u>sum of all observations divided by the number of observations</u>.
- The median of a data-set is the middle value of the data-set, the value which 50% of the measures are less and 50% are greater.
A distribution is classified as left skewed if the <u>mean is less than the median</u>.
In this problem, we have that most coins would be from the current year, hence the median should be the current year, while there are no coins from a year ahead of the current year and there should be a few coins of older years, hence the mean would assume a value less than the median and the distribution would be left skewed.

Answer:
The answer is D
Step-by-step explanation:
A cant be right because the graph isn't a straight line.
B cant be right because from 0 to 60 the graph the line goes at a(n) upward slope not a straight line.
Although the first part of question c is right, the second part is wrong. From 50-90 the ling goes at a downward slope via decreasing, which isn't equal like it said so question C is wrong.
So the correct answer is D
Answer:
25%
Step-by-step explanation:
First we calculate the probability of rolling a number greater than 3, that is, it can be 4, 5 or 6.
The probability of each number is 1/6, so:
P1 = (1/6) + (1/6) + (1/6) = 3/6 = 1/2
Then, we calculate the probability of rolling a prime number, that is, 2, 3 or 5.
As we have again 3 numbers, the probability P2 will also be 1/2
Then, the final probability is the product of both P1 and P2:
P = P1 * P2 = (1/2) * (1/2) = 1/4 = 25%
I think I believe it’s 8000
