Answer:
1/10
Step-by-step explanation:
To multiply 1/4 and 2/5 together, you just multiply straight across.
1/4 * 2/5 = 2/20
You can simplify this further by div'g by 2/2, so your final answer is 1/10.
The mean is 62 (496/8=62)
The median is 63 (52,52,52,62,64,69,69,76 take the two middle numbers and find the average 62+64/2=63)
The mode is 52 (there are three 52's)
The lowest score of a negatively skewed distribution is the mean.
A distribution can be symmetrical, negatively skewed or positively skewed.
For a symmetrical distribution, the mean, the median and the mode are all equal.
For a negatively skewed distribution, the mean is the lowest value, followed by the median and then the mode is the highest value.
For a positively skewed distribution, the mean is the highest value, followed by the median and the the mode is the lowest value.
