So you equal it to 90 and then minus and add the simulators to get x=25
9.3 boxes
Charles need 9.3
9.3 times 9.3 equals 84
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
Answer: i
Step-by-step explanation:square root of -1 is imaginary
The y values need to be on the top so it would be -2-8 over -4-3 so the answer would be 10/7
