Answer:

Step-by-step explanation:

f(x)= ax^3+bx^2+cx+d

f(-3)=-3a^3-3b^2-3c+d=0

f(3)=3a^3+3b^2+3c+d=0

f(5)=5a^3+5b^2+5c+d=0

f(0)=0a^3+0b^2+0c+d=2 <= any number you want your extremum at

=> d=2

f(-3)=-3a^3-3b^2-3c+=-2

f(3)=3a^3+3b^2+3c+=-2

f(5)=5a^3+5b^2+5c+=-2

solve for all variables ( Gauß )

a = 0.0266

b= -0.08

c= -0.66

Given OT with PQ = SR. What is the length of SR?

Ratling [72]

Answer:

42, because PQ is split in half and one side is 21, the 2 little lines going thru it show that both sides are equal meaning PQ is 42 bc of 21+21 therefore so is SR

A certain manufactured product is supposed to contain23% potassium by weight. A sample of 10 specimensof this product had an ave

inysia [295]

Answer:

a. The null and alternative hypothesis are

$H_0: \pi=23\\\\H_1: \pi\neq23$

b. P-value = 0.7181

c. The process should not be recalibrated. We have no enough statistical proof with this sample that the mean is not 23% (the null hypothesis π=23% could not be rejected).

Step-by-step explanation:

We want to know if there is enough statistical evidence to claim that the mean of the process is not 23%.

Then, the null and alternative hypothesis are

$H_0: \pi=23\\\\H_1: \pi\neq23$

We assume a significance level of 0.05.

The sample of size N=10 has a p=0.232.

The standard deviation to is

$\sigma=\sqrt{\frac{\pi(1-\pi)}{N} } =\sqrt{\frac{0.23(1-0.23)}{10} }=0.133$

The test statistic z is given by

$z=\frac{p-\pi-0.5/N}{\sigma}=\frac{0.232-0.2-0.5/10}{0.133}=\frac{-0.048}{0.133}=-0.361$

The two-tailed P-value for z=-0.361 is P=0.7181. This value is bigger than the significance level, so the effect is not significant. The null hypothesis can not be rejected.

That means we have no statistical proof with this sample that the mean is not 23%. The process should not be recalibrated.
