Answer:
64 degrees
Step-by-step explanation:
-add 94 and 22 together (116)
-subtract 116 from 180 (64)
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:
-21.5
Step-by-step explanation:
-12-6=-18 minus 3.5=-21.5
Answer:
30 degrees
Step-by-step explanation:
All angles of a triangle have to add up to 180
90 + 60 = 150
180 - 150 = 30
real part of x(y)=4*2-(-9*5)=53 so 1 is x(y): real part of x(y)=
real part of 2x(y)=2*53=106 so 2 is 2x(y)
real part of -x+3y=-4+6=2 so 3 is -x + 3y
real part of 4x-y=16-2=14 so 4 is 4x - y
