21x -15 + 5 = 10x - 5
21x -5 = 10x
11x = 5
x = 5/11
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.
I think the answer is A.
I haven't learnt this but I think the answer is A.
Reason:
1×8=8
2×8=16
3×8=24
And so.....
<span>5x-0.1=4x
Subtract 5x from both sides so that the x variable is only on one side
-0.1=-x
Divide both sides by -1 to get rid of the negative on the side with the x variable
Final Answer: 0.1=x</span>

<h3>1.) Subtract 14 from both sides:</h3>
Cancels Out
<em> - We do this because we have to get 2 variables/numbers on each side of the equals, and the only way to do so is to cancels other numbers out by doing the opposite of what we see. </em>
<u>Equation at the end of Step 1: </u>
÷ 
<h3>2.) Multiply both sides by −0.8:</h3>
