First, simplify. Combine each term. Remember to follow the Left to right rule

6/2 = 3 x 3 = 9

3 x 3 = 9

Finally, divide

9/9 = 1

(C) 1 is your answer

hope this helps

6/2*3 / 3(3)

First simplify the numerator: 6/2*3 = 3*3 = 9

Next simplify the denominator: 3(3) = 3*3 = 9

So you have 9/9, which equals 1.

The 3rd answer is correct.

The grade point averages (GPA) for 12 randomly selected college students are shown on the right. Complete parts (a) through (c)

Ilya [14]

Answer:

$\bar X =\frac{2.3+3.1+2.8+1.7+0.9+4+2.1+1.2+3.6+0.2+2.4+3.2}{12}=2.29$

$s=1.09$

Step-by-step explanation:

For this case we have the following data given:

2.3 3.1 2.8

1.7 0.9 4.0

2.1 1.2 3.6

0.2 2.4 3.2

Since the data are assumedn normally distributed we can find the standard deviation with the following formula:

$\sigma =\sqrt{\frac{\sum_{i=1}^n (X_i -\bar X)^2}{n}}$

And we need to find the mean first with the following formula:

$\bar X = \frac{\sum_{i=1}^n X_i}{n}$

And replacing we got:

$\bar X =\frac{2.3+3.1+2.8+1.7+0.9+4+2.1+1.2+3.6+0.2+2.4+3.2}{12}=2.29$

And then we can calculate the deviation and we got:

$s=1.09$

iVinArrow [24]

Answer:

Her hourly rate is $14.

Step-by-step explanation:

Given:

Penelope goes to work after school for 4.5 hours on Mondays, Tuesdays, and Fridays.

She works 8 hours each on Wednesdays or Thursdays.

Now, to find her hourly rate.

So, total hours Penelope work on Mondays, Tuesdays, and Fridays:

$4.5+4.5+4.5=13.5\ hours.$

And, total hours she work on Wednesdays and Thursdays:

$8+8=16\ hours.$

Now, the total hours each week she work:

$13.5+16=29.5\ hours.$

Total money she makes each week = $413.

Now, to get the hourly rate we divide the total hours each week she work by total money she makes each week:

$413\div 29.5$

$=\$14.$

Therefore, her hourly rate is $14.

Use decimals to answer the question what is 6% of 225

ElenaW [278]

Answer:

13.5

Step-by-step explanation:

(Are you meaning this as the answer is a decimal?)

3/50 * 225/1

Cross-cancel 50 and 225 by cancelling out 25.

3/2 * 9/1

Rewrite this so it is a single fraction.

(3 * 9)/2

Multiply 3 by 9 to get 27.

27/2

Divide 27 by 2 to get 13.5.

13.5

6% of 225 is 13.5.
