Answer:
i = -6
Step-by-step explanation:
3 - 2i + 8 = 23
3 + 8 - 2i = 23
11 - 2i = 23
11 - 11 - 2i = 23 - 11
-2i = 12
-2i ÷ -2 = 12 ÷ -2
i = -6
The hexagon is composed of two trapezoids (both of which are congruent). Let's find the area of the top trapezoid
A = h*(b1+b2)/2
A = 10*(40+10)/2
A = 10*(50)/2
A = 500/2
A = 250
Each trapezoid has area of 250 square units. So the combined area is 2*250 = 500 square units
The area of the hexagon is 500 square units.
Answer:
The interval will be narrower if the researchers increase the sample size of droplets.
Step-by-step explanation:
The confidence interval can be obtained using the relation :
Xbar ± Margin of error
Margin of Error = Zcrit * s/sqrt(n)
Zcritical = critical vlaue at the specified α - level
n = sample size ; s = standard deviation
Sample size being the denominator, will reduce the overall value of the error margin as we utilize a larger sample.
Hence, the interval becomes narrower as the error margin is reduced which is achieved by employing an increased sample size.
Answer:
I think you meant 4/20 but thats 20%
Step-by-step explanation:
U don't have to put this on the calculator because 20 to be 100 you have to multiply it by 5. So 4 times 5 is 20 so its 20% hope I helped :DD
