The area of the arrow given in the figure is 610 square cm
<h3>Area of composite figure</h3>
The given figure is made up of rectangle and triangle. The area is expressed as:
Area = Area of rectangle + area of triangle
Substitute the given parameters
Area of the arrow = (15*20) + 0.5(31 * 20)
Area of the arrow = 300 + 310
Area of the arrow = 610 square cm
Hence the area of the arrow given in the figure is 610 square cm

Answer:
sin5A+sin3A=cos2A-cos6A
2SIN((5A+3A)/2)COS ((5A-3A)/2)=2SIN((2A+6A)/2)SIN((2A-6A)/2)
-1/2sinA=1
-1/2=sinA
sinA=sin(180+30),sin(330)
:.A=210,330
Answer:
1. MN
2. PS
3. 42 degrees
Step-by-step explanation:
just substitute the first parallelogram with the second to find your answers.
Using the normal distribution, it is found that there is a 0.0548 = 5.48% probability that, in a given year, the rainfall is over 40 inches.
Normal Probability Distribution
In a normal distribution with mean 
and standard deviation 
, the z-score of a measure X is given by:
- It 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, which is the percentile of X.
In this problem:
- Mean of 32 inches, so
. - Standard deviation of 5 inches, so
.
The probability that, in a given year, the rainfall is over 40 inches is <u>1 subtracted by the p-value of Z when X = 40</u>, so:
has a p-value of 0.9452.
1 - 0.9452 = 0.0548.
0.0548 = 5.48% probability that, in a given year, the rainfall is over 40 inches.
