Answer:
48 ft cubed or 576 in cubed
Step-by-step explanation:
The volume of the water is 2304 in cubed. you multiply 12 in by 24 in by 8 in.
the rock makes the water go up 2 in. You then multiply 12 in by 24 in by 10 in. This will equal 2880 in cubed.
2880-2304=
576 in. cubed or 48 ft. cubed
Answer:
100
Step-by-step explanation:
First we find the mean of this set of data. We find the mean by finding the sum of data values and dividing it by the number of data values:
5+10+10+10+10+10+10+15 = 80
There are 8 data values; 80/8 = 10. The mean is 10.
To find the standard deviation, subtract the mean from each value; square the difference; add the squares; divide by the number of data values; and take the square root:
5-10 = -5; 10-10 = 0; 10-10 = 0; 10-10 = 0; 10-10 = 0; 10-10 = 0; 10-10 = 0; 15-10 = 5
(-5)^2 = 25; 0^2 = 0; 0^2 = 0; 0^2 = 0; 0^2 = 0; 0^2 = 0; 0^2 = 0; 5^2 = 25
25+0+0+0+0+0+0+25 = 50
50/8 = 6.25
√6.25 = 2.5
The standard deviation is 2.5.
This means two standard deviations, or 2σ, is 2(2.5) = 5.
This gives us μ-2σ = 10-5 = 5 and μ+2σ = 10+5 = 15.
Since all of our data is between 5 and 15, 100% is within two standard deviations of the mean.
Answer:
5.29
Step-by-step explanation:
<u>Step 1: Substitute 2.3 for A</u>
(a)^2
(2.3)^2
<em>5.29</em>
Answer: 5.29
Answer:
2n + 7
Step-by-step explanation:
Answer:
Yes
Step-by-step explanation:Given sides measurement satisfy Pythagoras theorem.
(5)^2=25
(3)^2+(4)^2=25
Thus it is a right angled ∆
