Calculate the standard deviation of the following test scores using 3 as score interval: 31 28 33 25 26 14 30 27 22 32 15 24 19 18 29 21 13 16 13 28 26 17 18 15 30 27 20 25 20 216​

step-by-step explanation:

here's what happens:

1) the graph of f   = x^2 is shifted 2 units to the right.

2) the resulting graph is reflected in the x-axis, so that the parabola now opens down.

3) this final result is transformed up by 5 units.

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x

a) 0

step-by-step explanation:

i^413 x i^0 = 0 as any number multiplied by a zero is
