Answer:

Mean: 6.25

Median: 5

Step-by-step explanation:

To find mean, you add all the numbers and then divide by the numbers you added.

Add: -25+10+4+-15+0+35+15+10=50
Divide: 50 divided by 8=6.25

To find median, you need to line up all the numbers from least to greatest, and find the number in the middle.

You find that 10 and 0 are in the middle.
In that case, you add 10+0=10
Divide: 10 divided by 2

Hope this helped!! :)

A tank holds 50 gal of water, which drains from a leak at the bottom, causing the tank to empty in 20 min. The tank drains faste

kirza4 [7]

Answer:

(a) V(0) = 50 gal, V(20) = 0 gal

(b)At t= 0 the tank is full.

At t=0 the tank is empty

(c)

Time volume

0 50 gal

5 37.5 gal

10 25 gal

15 12.5 gal

20 0 gal

(d)

Net change of volume = 50 gal

Step-by-step explanation:

Given that the capacity of the tank is 50 gal.

Torricelli's Law gives the volume of water remaining in the tank after t minutes as

$V(t)=50(1-\frac{t}{20})^2$

(a)

To find V(0), we put t = 0 in the above equation

$V(0)=50(1-\frac{0}{20})^2$

$=50(1-0)^2$

= 50 gal

To find V(20), we put t =2 0 in the above equation

$V(20)=50(1-\frac{20}{20})^2$

$=50(1-1)^2$

= 0 gal

(b)

At t= 0 the tank is full.

At t=0 the tank is empty.

(c)

Time V(t)

0 $50(1-\frac{0}{20})^2=50 \ gal$

5 $50(1-\frac{5}{20})^2=37.5 \ gal$

10 $50(1-\frac{10}{20})^2=25 \ gal$

15 $50(1-\frac{15}{20})^2=12.5 \ gal$

20 $50(1-\frac{20}{20})^2=0$

(d)

Net change of volume = V(0) -V(20)

=(50-0) gal

= 50 gal

A = {1, 3, 5, 7, 9}

ki77a [65]

Answer:

Option c. integers from 1 to 10 inclusive.

Step-by-step explanation:

The given sets are A = { 1, 3, 5, 7, 9 }

B = { 2, 4, 6, 8, 10 }

C = { 1, 5, 6, 7, 9 }

We have to determine A ∪ B

A ∪ B = { 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 }

Therefore, A ∪ B is the set of all from 1 to 10 inclusive.

option C will be the answer.
