Mathematics

Helga [31]3 years ago

Answer:

<h2>V = 27m³</h2>

Step-by-step explanation:

We know: All faces of a cube are squares.

The formula of an area of a square with a side <em>s</em>:

<em>A = s²</em>

We have <em>A = 9m²</em>

Substitute:

<em>s² = 9 → s = √9 = 3 m</em>.

The formula of a volume of a cube with an edge <em>s</em>:

<em>V = s³</em>

Substitute:

<em>V = 3³ = 27 m³</em>

Two bowlers bowl the following number of strikes in 9 games
ehidna [41]
First, let's calculate the mean and the mean absolute deviation of the first bowler.

FIRST BOWLER: <span>8,5,5,6,8,7,4,7,6
Mean = (Sum of all data)/(Number of data points) = (8+5+5+6+8+7+4+7+6)/9
<em>Mean = 6.222</em>
Mean absolute deviation or MAD = [</span>∑(|Data Point - Mean|]/Number of Data Points
MAD = [|8 - 6.222| + |5 - 6.222| + |5 - 6.222| + |6 - 6.222| + |8 - 6.222| + |7 - 6.222| + |4 - 6.222| + |7 - 6.222| + |6 - 6.222|]/9
<em>MAD = 1.136</em>

SECOND BOWLER: <span>10,6,8,8,5,5,6,8,9
</span>Mean = (Sum of all data)/(Number of data points) = (<span>10+6+8+8+5+5+6+8+9</span>)/9
<em>Mean = 7.222</em>
Mean absolute deviation or MAD = [∑(|Data Point - Mean|]/Number of Data Points
MAD = [|10 - 7.222| + |6 - 7.222| + |8 - 7.222| + |8 - 7.222| + |5 - 7.222| + |5 - 7.222| + |6 - 7.222| + |8 - 7.222| + |9 - 7.222|]/9
<em>MAD = 1.531
</em>

The mean absolute deviation represents the average distance of each data to the mean. Thus, the lesser the value of the MAD is, the more consistent is the data to the mean. <em>B</em><em>etween the two, the first bowler is more consistent.</em>

Moises ate 10% of the candies in the bag. If Moises ate 16 candies, how many candies were there total in the bag?
Viktor [21]

Answer:

160

Step-by-step explanation:

10% of the candies is 16, and to get 100% from 10% is to multiply by 10.

So 10% *10 = 100%, then by association if 16 = 10%, then 16*10 will be the total 100%.

Sample response:

Step-by-step explanation:

She would multiply the rate by the years to find the average rise in water levels, or 1.8 times 6.2 = 11.16. To find the difference between the water levels, she would subtract -13.64 from 11.16.
