A student performed the following steps to find the solution to the equation

PSYCHO15rus [73]

Answer:

Step 2

Step-by-step explanation:

Step 2 because in step 1, they correctly wrote the factors of the polynomial as (x+6) and (x-2). But then in step 2, (x+6) suddenly became (x-6) and (x-2) became (x+2), which is incorrect.

The answers in step 3 should have been -6 and 2.

What is the slope of the line, (-6, -8) and (2, 8)?

katrin [286]

Answer:

Your slope would be 2.

Step-by-step explanation:

To find the slope, you would need to use the formula: y2-y1/x2-x1

In this case, the equation would be 8-(-8)/2-(-6)

8 - (-8) = 16

2 - (-6) = 8

16/8 = 2

Slope: 2

In a data distribution, the first quartile, the median and the means are 30.8, 48.5 and 42.0 respectively. If the coefficient sk

RUDIKE [14]

Answer:

a) The third quartile Q₃ = 56.45

b) Variance $\mathbf{ \sigma^2 =2633.31}$

Step-by-step explanation:

Given that :

$Q_1$ = 30.8

Median $Q_2$ = 48.5

Mean = 42

a) The mean is less than median; thus the expression showing the coefficient of skewness is given by the formula :

$SK = \dfrac{Q_3+Q_1-2Q_2}{Q_3-Q_1}$

$-0.38 = \dfrac{Q_3+30.8-2(48.5)}{Q_3-30.8}$

$-0.38Q_3 + 11.704 = Q_3 +30.8 - 97$

$1.38Q_3 = 77.904$

Divide both sides by 1.38

$Q_3 = 56.45$

b) The objective here is to determine the approximate value of the variance;

Using the relation

$SK_p = \dfrac{Mean- (3*Median-2 *Mean) }{\sigma}$

$-0.38= \dfrac{42- (3 *48.5-2*42) }{\sigma}$

$-0.38= \dfrac{(-19.5) }{\sigma}$

$-0.38* \sigma = {(-19.5) }{}$

$\sigma =\dfrac {(-19.5) }{-0.38 }$

$\sigma =51.32$

Variance = $\sigma^2 =51.32^2$

$\mathbf{ \sigma^2 =2633.31}$

1/3 + -7/4 I am very confused

Lesechka [4]

Answer:

$-\frac{17}{21}$

Step-by-step explanation:

Negative and positive is negative.

Negative and negative is positive.

Positive and positive is positive.

$\frac{1}{3} +-\frac{7}{4}=\frac{1}{3}-\frac{7}{4} = -\frac{17}{12}$
