Answer:

m = 2

Step-by-step explanation:

take 2 pairs from x

choose (1,5) and (2,7)

it will be m = 5 - 7

and in the bottom 1 - 2 it's a fraction

m = -2/-1

the numerator and denominator can't be both negative

so your answer is m= +2

m= slope

rate of change= slope

Q1. Ten percent of the items produced by a machine are defective. A random sample of 100 items is selected and checked for defec

Tcecarenko [31]

Answer: 0.030

Step-by-step explanation:

Given: The percent of the items produced by a machine are defective : $P=10\%=0.10$

The percent of the items produced by machine which are not defective: $Q=1-0.1=0.9$

Sample size : n = 100

Now, the standard error of the proportion is given by :-

$\text{S.E.}=\sqrt{\dfrac{0.1\times0.9}{100}}\\\\\Rightarrow\text{S.E.}=0.030$

Hence, the the standard error of the distribution of the sample proportions=0.030

A line passes through point A (14,21). A second point on the line has an x-value that is 125% of the x-value of point A and a y-

seropon [69]

Answer:

The equation of the line in point-slope form is $y-21 = - \frac{3}{2}\cdot (x-14)$ .

Step-by-step explanation:

According to the statement, let $A(x,y) = (14,21)$ and $B(x,y) = (1.25\cdot x_{A},0.75\cdot y_{A})$ . The equation of the line in point-slope form is defined by the following formula:

$y-y_{A} = m\cdot (x-x_{A})$ (1)

Where:

$x_{A}$ , $y_{A}$ - Coordinates of the point A, dimensionless.

$m$ - Slope, dimensionless.

$x$ - Independent variable, dimensionless.

$y$ - Dependent variable, dimensionless.

In addition, the slope of the line is defined by:

$m = \frac{y_{B}-y_{A}}{x_{B}-x_{A}}$ (2)

If we know that $x_{A} = 14$ and $y_{A} = 21$ , then the equation of the line in point-slope form is:

$x_{B} = 1.25\cdot (14)$

$x_{B} = 17.5$

$y_{B} = 0.75\cdot (21)$

$y_{B} = 15.75$

From (2):

$m = \frac{15.75-21}{17.5-14}$

$m = -\frac{3}{2}$

By (1):

$y-21 = - \frac{3}{2}\cdot (x-14)$

The equation of the line in point-slope form is $y-21 = - \frac{3}{2}\cdot (x-14)$ .

dedylja [7]

Answer:

R(s) $\geq 2000$ ,

Step-by-step explanation:

The function R(s) = 20s

She needs to sell at least 100 subscriptions, so the least amount she wants to have is: 20*100 = $2000

Hence, is the domain of R(s) in this context

R(s) $\geq 2000$

Hope it will find you well
