If p() = x2 - 1 and q(x) - 5(x-1), which expression is equivalent to (p - q)(x)?

TiliK225 [7]

Answer:

$\text{If p(x) = x2 - 1 and q(x) = 5(x - 1), the expression which is equivalent to}$ $\text{ (p - q)(x) is (x2 - 1) - 5(x - 1).}$

Step-by-step explanation:

Given:

p(x) = 2x2 - 1
q(x) = 3(x - 1)

To find:

(p - q)(x)

We know:

(p - q)(x) = p(x) - q(x)

Substitute

(2x^2 - 1) - 3(x - 1)

$\text{Therefore, the expression equivalent to (p - q)(x) is (2x2 - 1) - 3(x - 1).}$

What is the statistical decision regarding the differences between the observed and expected frequencies if the critical value o

mel-nik [20]

Answer:

Fail to reject.

Step-by-step explanation:

For a goodness of fit test the decision rule is:

If the calculated value of the test statistic is more than the right tailed critical value of chi-square, then the null hypothesis will be rejected.

The hypothesis for a goodness of fit test is:

<em>H</em>₀: There is no differences between the observed and expected frequencies.

<em>Hₐ</em>: There is a significant differences between the observed and expected frequencies.

The computed value of the test statistic is, 6.079.

The critical value of chi-square is 9.488.

Calculated test statistic < Critical value

6.079 < 9.488

Thus, the null hypothesis was failed to rejected.

Answer:

The scale factor is $\frac{3}{2}$

Step-by-step explanation:

The volume of the original prism is $V_P=980cm^3$

The volume of the dilated prism is $V_Q=3307.5cm^3$

Let the scale factor be $k$ .

To find the volume of the dilated prism, we multiplied by $k^3$ .

$\Rightarrow 980k^3=3307.5$

$\Rightarrow k^3=\frac{3307.5}{980}$

$\Rightarrow k^3=\frac{27}{8}$

$\Rightarrow k=\sqrt[3]{\frac{27}{8}}$

$\Rightarrow k=\frac{3}{2}$
