ANSWER

$(5 - 2 {i}^{2} ) ^{2} = 49$

EXPLANATION

The given expression is

$(5 - 2 {i}^{2} ) ^{2}$

This is an expression containing a complex number.

Recall that in complex numbers,

${i}^{2} = - 1$

The expression now becomes,

$(5 - 2 {i}^{2} ) ^{2} = (5 - 2 ( - 1) ) ^{2}$

This implies that,

$(5 - 2 {i}^{2} ) ^{2} = (5 + 2 ) ^{2}$

This will simplify to,

$(5 - 2 {i}^{2} ) ^{2} = {7}^{2}$

This eventually gives us,

$(5 - 2 {i}^{2} ) ^{2} = 49$

Irina says she can find the range of a set of data from a histogram. Is she correct? Justify your answer.

monitta

Yes, histograms main purpose to show ranges from a graph. so like lets say you have a problem where you have ranges of different ages like people from 20-29, 30-45, 46-65, 66-85, you would put that on the y axis and the amount of people on the x axis
