Answer:

The answer is 41

Step-by-step explanation:

400 = 900 + 625 - 1500 cos x

400 - 1525 = -1500 cos x

-1125 = -1500 cos

cos x = -1125/-1500

x = cos⁻¹ 0.75

x = 41.409622109

x ≈ 41°

Answer:

required probability is .3446

Step-by-step explanation:

It is given that most expected time of completion = 90 days

Variance = 25

We know that

$\sigma =\sqrt{Variance}\\\\\sigma =\sqrt{25}\\\sigma =5$

Thus the standard normal deviate is given by

$Z=\frac{X-\bar{X}}{\sigma }$

Applying values we get

$Z=\frac{88-90}{5}\\\\Z=-0.4$

Using the standard table for Z we have probability corresponding to Z = -0.4 equals 0.3446

Thus required probability is .3446
