1) What you see as 3
can be also changed to only a fraction, by changing
to
, but since the question wants 2 as a whole number, we must take out
and then add the 8 eights to the other 3, to get <span>
</span>for # 10- 13, you need to have the same number on the bottom of all the numbers being subtracted, that means turning the number that aren't fractions (like 4) into fraction, and then into fractions with the same denominators.
10)
changes to
to get

11)
changes to

Answer:
A value two standards deviation from the mean is more likely to occur than a value three standard deviations from the mean.
Step-by-step explanation:
Standard deviation is a quantitative measure of the variability of traits of the subjects in a given population. These traits can range from age, height, weight e.t.c. This deviation is brought about by extreme or abnormal conditions, which is the reason why two deviations is more likely to occur than three deviations.
Moreover, going by the provisions of the empirical rule, If data comes from a population that is approximately symmetrical;
95% of the data will fall within two standard deviations.
99.7% will fall within three standard deviations
Find the attachment below.
Nevertheless, in a symmetrical distribution most of the data values fall around the mean. Two standard deviations is closer to the mean than 3 standard deviations hence more likely to occur.
Answer:
Rudy is 13 years old. Her father is 45 years old.
Step-by-step explanation:
It's very simple actually!
<u>All you need to do is subtract 32:</u>
58 - 32 = 26
<u>Then divide:</u>
<u />
26 ÷ 2 = 13
13 is Rudy's age. Let's find her father's age!
<u>We then add 32 back to 13:</u>
32 + 13 = 45
And there you have it!
Hope this helped! :)
