1) You are told the conversion of cubic inches to gallons, but
first you need to find the volume of the fish tank in cubic inches.
The equation for the volume of a rectangular prism (shape of the fish tank) is V = lwh, where V = volume, l = length of the base, w = width of the base, and h = height of the tank. You know the dimensions are<span> 36 inches by 13 inches by 24 inches. Plug these numbers into the equation to find the volume:
</span>
2) You know the conversion from cubic increase to gallon is <span>231 cubic inches in 1 gallon. That means
the three gallon bucket is 231*3 = 693 cubic inches. Divide 11232 by 693 and round up (since you're partially filling it up once) to find the number of times Valeria needs to fill the bucket:

Answer: 17 times</span>
OK the question is asking what happens when you subtract (1.9+2.2) from 1.9x2.2 or more clearly 1.9x2.2-(1.9+2.2) which equals 4.18-4.1 or .08

Answer:
3y = 4 or 3y - 4 =0
Step-by-step explanation:
Answer:
And we can find this probability with this difference and using the normal standard table or excel:
And the result is illustrated in the figure attached.
Step-by-step explanation:
Previous concepts
Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".
The Z-score is "a numerical measurement used in statistics of a value's relationship to the mean (average) of a group of values, measured in terms of standard deviations from the mean".
Solution to the problem
Let X the random variable that represent the variable of interest of a population, and for this case we know the distribution for X is given by:
Where and
We are interested on this probability
And the best way to solve this problem is using the normal standard distribution and the z score given by:
If we apply this formula to our probability we got this:
And we can find this probability with this difference and using the normal standard table or excel:
And the result is illustrated in the figure attached.
