Answer: Real world problem is "A student have c toffee he distribute th part of those toffees to his friends. He gave total 21 toffees to his friend".
Explanation:
Let a student have c number of toffees in his bag.
It is given that he distribute th part of those toffees to his friends.
The th part of c toffees is,
The total number of distributed toffees is 21.
It is the same as given equation.
If we change the equation in words it means the th part of a number c is 21.
<u>A
</u><u />You can find the area of a trapezoid with a+b/2*h. If you do so with those numbers, you will get 108.
<u>B
</u><u /><u />If you multiply 2.5 by 108, you can find the cost to tile the entire trapezoid. This is $270 even.
<u>C
</u><u />To solve for the area of a parallelogram, you can simply multiply bh. If you do so with these numbers, you will get 96.
<u>D
</u><u />If you multiply 3 by 96, you can find the cost to tile the entire parallelogram. This is $288 even.<u>

Answer:
0.5793 = 57.93% probability that the household uses 480 gallons of water or less per month
Step-by-step explanation:
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean and standard deviation , the z-score of a measure X is given by:
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.
Mean of 470 gallons and standard deviation of 50 gallons.
This means that
What is the probability that the household uses 480 gallons of water or less per month?
This is the pvalue of Z when X = 480. So
has a pvalue of 0.5793
0.5793 = 57.93% probability that the household uses 480 gallons of water or less per month
Subtract the expression on the right of the equal sign. Collect terms. (Write the exponent properly.)
.. x² -9x +20 = 0
