Kevin bought 3 bags of gravel to cover the bottom of his fish tank. He has 8 pounds of gravel left over. how much gravel did Kev
2 answers:
Answer:
(3x - 8) pounds of gravel was used to cover the bottom of sinks, where x is the weight of bag of gravel.
Step-by-step explanation:
We are given the following information in the question:
In order to answer this question we need to make the following assumption
Let x pound be the weight of one bag of gravel.
Total number of bags of gravel bought by Kevin = 3
Weight of 3 bags of gravel = 3x pounds
Amount of gravel left after pouring = 8 pounds
Amount of gravel used to cover the bottom of sink =
Formula:
Thus, (3x - 8) pounds of gravel was used to cover the bottom of sinks.

A^2+ 12^2 = 15^2
a^2 + 144 = 225
225 - 144 = 81
square root of 81 = 9
a = 9
a^2 + 144 = 225
225 - 144 = 81
square root of 81 = 9
a = 9
Answer:
The probability that a randomly selected depth is between 2.25 m and 5.00 m is 0.55.
Step-by-step explanation:
Let the random variable <em>X</em> denote the water depths.
As the variable water depths is continuous variable, the random variable <em>X</em> follows a continuous Uniform distribution with parameters <em>a</em> = 2.00 m and <em>b</em> = 7.00 m.
The probability density function of <em>X</em> is:
Compute the probability that a randomly selected depth is between 2.25 m and 5.00 m as follows:
Thus, the probability that a randomly selected depth is between 2.25 m and 5.00 m is 0.55.
Answer:
Step-by-step explanation:
Mod of any number represents the absolute value of the number.
Therefore, = 2.25
Now we can arrange these numbers in ascending order.
-2.25 < -1.25 < 0.75 < 1.25 < 1.75 < 2.25
Therefore,
