8n+52=12(n+2)
distribute
8n+52 = 12n+24
subtract 8n from each side
52=4n +24
subtract 24 from each side
28 = 4n
divide by 4 on each side
7=n
Answer:
the solution for x will be given by {x| -13 < x < 13}
Therefore the correct option is B.
Step-by-step explanation:
i) given that |x| < 13
ii) therefore x < 13 for positive values of x
iii) for negative values of x we have -x < 13
therefore x > -13
iv) from ii) and iii) above we can conclude that the solution for x will be given by {x| -13 < x < 13}
Therefore the correct option is B.
Answer:
either 5 or 11
Step-by-step explanation:
(8, -12)
(5, -9) or (11, -9)
If y varies consistently with x then it would copy what happens, in a manner of speaking.
In this case, y increases by three, x would either add 3 or subtract 3
I am not completely sure on this.
Using the Empirical Rule, it is found that 95% of the employees will have a travel time within the following range:
B. 8 minutes to 28 minutes.
<h3>What does the Empirical Rule state?</h3>
It states that, for a normally distributed random variable:
- Approximately 68% of the measures are within 1 standard deviation of the mean.
- Approximately 95% of the measures are within 2 standard deviations of the mean.
- Approximately 99.7% of the measures are within 3 standard deviations of the mean.
Considering that the mean time is 18 minutes and the standard deviation is 5 minutes, the the bounds of the 95% range are given by:
Hence option B is correct.
