Answer:
3.84% of months would have a maximum temperature of 34 degrees or higher
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 percentage of months would have a maximum temperature of 34 degrees or higher?
This is 1 subtracted by the pvalue of Z when X = 34. So
has a pvalue of 0.9616
1 - 0.9616 = 0.0384
3.84% of months would have a maximum temperature of 34 degrees or higher
The area of the parallelogram is mathematically given as
A = 7 square units Option B
<h3>What is the area of the parallelogram?</h3>Generally, the equation for a parallelogram is mathematically given as
A=bH
Where
b=4.123
and
H=1.75
Hence
A=3*1.75
A=7.2square units
In conclusion, a parallelogram
A = 7 square units

The area of the triangle can be calculated using the distance formula if the coordinates are given.
<h3>What is the triangle?</h3>The triangle can be defined as a three-sided polygon in geometry, and it consists of three vertices and three edges. The sum of all the angles inside the triangle is 180°.
We have a triangle with coordinates on the coordinate plane.
It is required to find the area of the triangle using the coordinate points.
Here the coordinates are not given, so we are assuming the coordinates are (x1, y1), (x2, y2), (0,0)
From the distance formula:
The distance(b) between (0, 0) and (x1, y1):
The distance between (0, 0) and (x2, y2):
So the area of the triangle:
A = bh/2
Thus, the area of the triangle can be calculated using the distance formula if the coordinates are given.
