The z or t score to be used is (0.422,0.978)
How to find the critical value ?
Critical probability (p*) = 1 - (Alpha / 2), where Alpha is equal to 1 - (the confidence level / 100), is the unit statisticians use to determine the margin of error within a set of data in statistics.
The critical value for α = 0.13 is
The corresponding confidence interval is computed as shown below


CI = (0.422, 0.978)
0.422< mu1 - mu 2 < 0.978

Equation;
2a + 3b - 3c + 4b
Find:
Solution
Computation:
2a + 3b - 3c + 4b
2(3) + 3(-2) - 3(5.1) + 4(-2)

Explicação passo a passo:
Das opções fornecidas:
Todas as opções atendem à condição de uma matriz quadrada, pois todas têm o mesmo número de linhas e colunas (2 * 2)
Para ter uma matriz diagonal, todas as entradas fora da diagonal principal serão Zero.
Por outro lado, a matriz de identidade é um tipo especial de matriz quadrada com uma ao longo da diagonal principal.
Indo por essas condições apenas a matriz (b); atende às três condições.
It's the same as normal division. All you need to do is add the decimal in. Let me show you:
2.5/2
2/2 What's 2 divided by 2? It's <em><u>1</u></em><em><u>.</u></em>
.5/2 What's 5 divided by 2? <u>2.5</u>, right? But since it's .5 (not 5) divided by 2, the decimal goes somewhere else.<em> Since the 5 comes just to the right of the decimal, so will the <u>25</u>. You have </em><em><u>.25</u></em><u>.</u>
<em><u>1 + .25 = 1.25</u><u /></em>. And that's the answer! 2.5/2=1.25. See how I broke it up into pieces? It makes life easier.
