1.5c - 7 because the it says 7 less than, so subtraction, then it says 1.5 times a number so just any letter i chose c for carnation bushes.
Answer:
x-3
Step-by-step explanation:
5x²-15x
in order to get the equivalent of the equation, simplify to the lowest term.
To simplify to the lowest term, divide through by the common factor in the equation which is 5x
5x²÷5x - 15x÷5x
=x-3
Answer:
The maximum amount of sand that can be stored in this structure is 1675.52 m³.
Step-by-step explanation:
The volume of a conical-shaped structure is given by
Where r is the radius and h is the height of the structure.
We are given that
radius = 10m
height = 16m
Substituting the above values into the formula, we get
Therefore, the maximum amount of sand th can be stored in this structure is 1675.52 m³.

Answer:
0.5 = 50% probability a value selected at random from this distribution is greater than 23
Step-by-step explanation:
Problems of normally distributed samples are solved using the z-score formula.
In a set with mean and standard deviation , the zscore 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 pvalue, we get the probability that the value of the measure is greater than X.
In this problem, we have that:
What is the probability a value selected at random from this distribution is greater than 23?
This is 1 subtracted by the pvalue of Z when X = 23. So
has a pvalue of 0.5
0.5 = 50% probability a value selected at random from this distribution is greater than 23
