Sea level is 0

robert dives 40 ft.....-40
he then rises 23 ft.....-40 + 23 = -17
he then dives 19 ft to meet Sam....-17 - 19 = -36
together they rise 31 ft...-36 + 31 = - 5

Frankie has guinea pigs, a land tortoise, and a hamster. The hamster needs 4 oz of food every 6 hours. The guinea pig needs 12 o

Anit [1.1K]

The hour all animals get fed at the same time if Frankie starts at 6:00 Am is 6:00 pm

<h3>Common multiple</h3><h3 />

Hamster 4oz of food = 6 hours
Guinea pigs 12oz of food = 12 hours
Land tortoise 24oz of food = 24 hours

Find the lowest common multiple

6 hours = 6, 12, 18, 24
12 hours = 12, 34, 36
24 hours = 24, 48, 72

The lowest common multiple of 6, 12 and 24 is 12

if Frankie starts at 6:00 Am?

6:00 am + 12 hours

= 6:00 pm

Therefore, the hour all animals get fed at the same time if Frankie starts at 6:00 Am is 6:00 pm

The average number of minutes Americans commute to work is 27.7 minutes. The average commute time in minutes for 48 cities are a

dolphi86 [110]

Answer:

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

And replacing we got:

$\bar X = 27.2$

b) For this case we have n =48 observations and we can calculate the median with the average between the 24th and 25th values on the dataset ordered.

20.4 20.4 20.5 21.7 22.3 23.3 23.6 23.7 23.7 23.7 23.9 23.9 24.1 24.3 24.7 24.9 25.1 25.1 25.1 25.2 25.3 25.6 26.1 26.1 26.4 26.5 26.7 27.1 27.1 27.4 27.6 28.4 28.6 28.6 28.7 28.8 28.8 29.6 31.0 32.0 32.0 32.4 32.5 32.9 33.1 34.5 38.4 44.1

For this case the median would be:

$Median = \frac{26.1+26.4}{2}=26.25 \approx 26.3$

c) $Mode= 23.2, 25.1$

And both with a frequency of 3 so then we have a bimodal distribution for this case

Step-by-step explanation:

For this case we have the following dataset:

23.6, 26.5, 28.6, 28.6, 23.7, 25.3, 24.9, 28.7, 26.7, 32.4, 20.4, 23.9, 32.0, 32.5, 23.7, 26.1, 21.7, 26.1, 38.4, 24.1, 20.5, 25.2, 31, 26.4, 27.1 ,25.1, 25.1, 23.7, 23.9, 32.9, 28.8, 25.6, 28.8, 28.4, 32, 27.6, 29.6, 44.1, 27.1, 24.7, 22.3, 24.3, 23.3, 27.4, 20.4, 25.1, 34.5, 33.1

Part a

We can calculate the mean with the following formula:

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

And replacing we got:

$\bar X = 27.2$

Part b

For this case we have n =48 observations and we can calculate the median with the average between the 24th and 25th values on the dataset ordered.

20.4 20.4 20.5 21.7 22.3 23.3 23.6 23.7 23.7 23.7 23.9 23.9 24.1 24.3 24.7 24.9 25.1 25.1 25.1 25.2 25.3 25.6 26.1 26.1 26.4 26.5 26.7 27.1 27.1 27.4 27.6 28.4 28.6 28.6 28.7 28.8 28.8 29.6 31.0 32.0 32.0 32.4 32.5 32.9 33.1 34.5 38.4 44.1

For this case the median would be:

$Median = \frac{26.1+26.4}{2}=26.25 \approx 26.3$

Part c

For this case the mode would be:

$Mode= 23.2, 25.1$

And both with a frequency of 3 so then we have a bimodal distribution for this case

What is the multiplication problem that means the same thing as the division problem 1/9 divided by 12?

lianna [129]

/Hello!

See below

We need to find x. X being the answer to 1/9 divided by 12.

1/9÷12=1/108.

=1×1/9×12

=11/08

=1/108

Now that we know what "x" equals, we can divide the others.

1/9x12=1 and 3/9 ------simplifed is------1 and 1/3

Convert any mixed numbers to fractions

.

Then your initial equation becomes:

1/9×12/1

Applying the fractions formula for multiplication,

=1×12/9×1

=12/9

Simplifying 12/9, the answer is

=1 and 1/3

This is not correct.

1/9×1/12

Applying the fractions formula for multiplication,

=1×1/9×1/2

=1/108

This is correct.

Therefore, your answer is B. 1/9 x 1/12
