Correction:
I think the question should be like that find the approximate value of
P(-0.78 < z < 1.16)?
Now,
the symbol Ф represent the cumulative density.
first find the
Ф(1.16) from the above given table which is equal to 0.8770.
Now,
find the Ф(-0.78) .
in our table we are given the value of Ф(0.78)=0.7823
so as the curve is symmetrical Ф(-0.78)=1-0.7823=0.2177
P(-0.78 < z < 1.16) = Ф(1.16)-Ф(-0.78)
= 0.8770-0.2177
= 0.6593

Explicação passo a passo:
Área do retângulo = comprimento * largura
Dado
Comprimento = 4
Largura = 3x + 2
Área = 44
Substitua na fórmula e obtenha x
44 = 4 (3x + 2)
44 = 12x + 8
12x = 44-8
12x = 36
x = 36/12
x = 3
Obtenha os lados mais longos
Lado mais longo = 3x + 2
Substitua x = 3
Lado mais comprido = 3 (3) + 2
Lado mais comprido = 11
Portanto, a medida do lado mais longo deste retângulo é 11

Step-by-step explanation:
You answered correctly for part a. just simplify it. so for part a it would be x^4 + 8x^3 + 24x^2 + 32x + 16. repeat what you did in part a with part b (add & simplify). btw, the missing side in part c is 2x-x = x
