Look at the picture.
The area of a parallelogram:
The area of a triangle:
The area of the polygon:
[texA=A_P+A_T\\\\A=15+12.5=27.5\ u^2[/tex]
Answer: D. 27.5 square inches /inches?/ I think, correct is units
If the painting lies in the middle of the rectangle and half of 20 f is 10 so then half of the painting that is on half of the wall would be only 1.2f if you take 10-1.2= 8.8f your final answer.
The triangle to solve for has a leg or 12 feet, hypotenuse of 20 feet, so solve for Pythagoras
for a
a = 16 feet
Answer: 5
Step-by-step explanation:
To solve for the confidence interval for the population
mean mu, we can use the formula:
Confidence interval = x ± z * s / sqrt (n)
where x is the sample mean, s is the standard deviation,
and n is the sample size
At 95% confidence level, the value of z is equivalent to:
z = 1.96
Therefore substituting the given values into the
equation:
Confidence interval = 3 ± 1.96 * 5.8 / sqrt (51)
Confidence interval = 3 ± 1.59
Confidence interval = 1.41, 4.59
Therefore the population mean mu has an approximate range
or confidence interval from 1.41 kg to 4.59 kg.
