Ann [662]

Answer:

0.0698

Step-by-step explanation:

Given :

Population mean, μ = 20

Sample mean, xbar = 21.1

Sample standard deviation, s = 4.3

Sample size, n = 35

The hypothesis :

H0 : μ = 20

H0 : μ > 20

The test statistic :

(xbar - μ) ÷ (s/√(n))

T = (21.1 - 20) ÷ (4.3/√(35))

T = 1.1 ÷ 0.7268326

Test statistic = 1.513

Using the Pvalue calculator :

df = n - 1 = 35 - 1 = 34

Pvalue(1.513, 34) = 0.06976

Pvalue = 0.0698 (4 decimal places)

Given the following table, find the rate of change between f(-4) and f(0).

Virty [35]

Answer: The correct option is (B) $\dfrac{1}{2}.$

Step-by-step explanation: We are given to find the rate of change between f(-4) and f(0) from the following table:

x -4 -2 0 2 4

f(x) -2 -1 0 1 2

The average rate of change of a function f(x) from x = a to x = b is given by

$A=\dfrac{f(b)-f(a)}{b-a}.$

From the given table, we have

f(-4) = - 2 and f(0) = 0.

Therefore, the average rate of change between f(-4) and f(0) is given by

$A=\dfrac{f(0)-f(-4)}{0-(-4)}=\dfrac{0-(-2)}{0+4}=\dfrac{2}{4}=\dfrac{1}{2}.$

Thus, the required rate of change is $\dfrac{1}{2}.$

Option (B) is correct.

3p- 2c^3- 3c^3p +2 Write as a product

astra-53 [7]

Answer:

$(3p + 2) (1 - c)(1 + c + {c}^{2} )$

Step-by-step explanation:

$3p- 2c^3- 3c^3p +2 \\ \\ = (3p - 3 {c}^{3} p) +( 2 - 2c^3) \\ \\ = 3p(1 - c^3) + 2(1 - c^3) \\ \\ = (1 - c^3)(3p + 2) \\ \\ = (1 - c)(1 + c + {c}^{2} )(3p + 2) \\ \\ = \bold{ \red{(3p + 2) (1 - c)(1 + c + {c}^{2} )}}$
