It is a scalene triangle bc it has no equal sides
You will use trig. Try the phrase “SohCahToa” you will use “Soh” meaning Sin is opposite over hypotenuse. So in this instance, it would be sin(x)=8/11. You will need to take the inverse sine to figure out x. So, x= sin^-1(8/11) which turns out to be approximately 46.65°
Just subtract 6-6 and 8-6 then divide 1/2 by both sides
Answer:
3972.72 specimens
Step-by-step explanation:
We solve using the z score formula:
z = (x-μ)/σ where
x is the raw score = 73 cm
μ is the population mean = 147 cm
σ is the population standard deviation = 30 cm
N is the number of samples = 4000
For x > 73
z = 73 - 147/30
z = -2.46667
Probability value from Z-Table:
P(x<73) = 0.0068189
P(x>73) = 1 - P(x<73) = 0.99318
The probability of having a height greater than 73cm is: 0.99318
The number of specimens that have a height greater than 73cm is calculated as: 0.99318 × 4000
= 3972.72 specimens
