Given simplification:

3√7 + 7√63 + (√7/7)

= 3√7 + 7√(9*7) + (√7/7)

= 3√7 + 7*3√7 + (√7/7)

= 3√7 + 21√7 + (√7/7)

= (3+21)√7 + (√7/7)

= 24√7 + (√7/√7)

= (7*24√7 + √7)/7

= (168√7 + √7)/7

= (169√7)/7

<u>Answer</u><u>:</u><u>-</u> 3√7 + 7√63 + (√7/7) = (169√7)/7.

jeni works from 8:00-3:15 three days in a row, only taking a half-hour unpaid lunch break each day. if she is paid $15 per hour,
enyata [817]

Jeni gets paid $ 303.75 for 3 days

<em><u>Solution:</u></em>

Given that,

Jeni works from 8:00-3:15 three days in a row

<em><u>Find the number of hours between 8 : 00 to 3 : 15</u></em>

8 : 00 to 3 : 15 = 7 hours 15 minutes

She is taking half-hour unpaid lunch break each day

7 hours 15 minutes - half an hour = 6 hours 45 minutes

So, she works for 6 hours 45 minutes for each three days

6\ hours\ 45\ minutes = 6 + \frac{45}{60} = 6 + 0.75 = 6.75\ hours

She is paid $15 per hour

<em><u>Therefore, total earnings for 3 days is given as:</u></em>

Total\ Earnings = 3 \times 15 \times 6.75\\\\Total\ Earnings = 303.75

Thus she gets paid $ 303.75 for 3 days

Assume that the GMAT scores across the U.S. follow a bell shaped distribution (symmetric and unimodal) with mean 549 and standar
blondinia [14]

Answer:

The GMAT score corresponding to the 16th percentile is 473.

Step-by-step explanation:

Empirical Rule.

The Empirical Rule 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.

68% of the measures within 1 standard deviation of the mean.

This means that they are between the 50 - (68/2) = 50 - 34 = 16th percentile(one standard deviation below the mean) and the 50 + (68/2) = 50 + 34 = 84th percentile(one standard deviation above the mean).

In this question:

Mean of 549, standard deviation of 76.

16th percentile:

One standard deviation below the mean, so 549 - 76 = 473.

The GMAT score corresponding to the 16th percentile is 473.
