Given :-

Diameter of tank = 20 feet

Radius of tank, r = 20/2 = 10 feet

To Find :-

Volume of the hemisphere

Formula to be used :-

Volume of the hemisphere = 2/3 × π × r³

Solution :-

Putting the values, we get

Volume of the hemisphere = 2/3 × π × r³

⇒ Volume of the hemisphere = 2/3 × 22/7 × 10 × 10 × 10

⇒ Volume of the hemisphere = 44000/21

⇒ Volume of the hemisphere = 2095. 23 feet³

Now, Total weight of the water

⇒ Total weight of the water = 62.4 × 2095.23

⇒ Total weight of the water = 130742.35 pounds

Hence, the Total weight of the water is 130742.35 pounds

Use synthetic division to find the result when 3x^3 + 13x^2 + x – 12 is divided by<br> X + 4.

IgorC [24]

Answer:

3x² + x - 3

Step-by-step explanation:

The way I like to do it is to get rid of the x's and just use the numbers in the case of synthetic division

Pretend the square root of the division symbol

-4 √ 3 12 1 -12

Quick note: We're dividing by -4 because we're dividing by x + 4

First bring down the 3

-4 √ 3 13 1 -12

Multiply it by 4 then bring add it to the next number

-4 √ 3 13 1 -12

-12

3 1

Add that number to the next one

-4 √ 3 13 1 -12

-12 -4

3 1 -3

Finally repeat the step for the last number

-4 √ 3 13 1 -12

3 -12 -4 +12

3 1 -3 0

Now take those bottom numbers and add back the x's but with one less power, so the starting x³ would now become x², x² would become x, and so on

3x² + 1x - 3

Suppose a population has a mean of 7 for some characteristic of interest and a standard deviation of 9.6. A sample is drawn from

valkas [14]

Answer: A. 1.2

Step-by-step explanation:

Given : Sample size : n= 64

Standard deviation: $\sigma=9.6$

The formula to find the standard error of mean is given by :-

$S.E.=\dfrac{\sigma}{\sqrt{n}}\\\\\Rightarrow\ S.E.=\dfrac{9.6}{\sqrt{64}}\\\\\Rightarrow\ S.E.=\dfrac{9.6}{8}=1.2$

Therefore, the standard error of the mean= 1.2

Hence, A is the right option.
