Answer:
Evaluate ∫3x2sin(x3)cos(x3)dx
Step-by-step explanation:
hello (a) using the substitution u=sin(x3) because
du =3x²(cos x3)dx
you have ∫3x2sin(x3)cos(x3)dx = ∫udu=u²/2 +c............continu
Answer:
We are given that a Psychologist claims that less than 5.8 percent of the population suffers from professional problem due to extreme shyness.
We are supposed to set up the null and alternative hypotheses.
Since the claim is less than 5.8 percent, therefore, the claim will be mentioned in the alternative hypothesis. Hence the null and alternative hypotheses are given below:


Therefore, the option a. H0: p = 5.8% H1: p < 5.8% is correct

Answer:
Step-by-step explanation:
A = 150°
B = 12°
C = 180 - (150 + 12) = 18°
b = 10 cm
Apply the sine rule:

Plug in the values

Multiply both sides by sin(18)


c = 14.9 cm (nearest tenth)
