Complete the description of the slope of the line that joins the points

Grace [21]

Answer:

The slope of the line that joins the points is negative.

i.e m = -6/5

Step-by-step explanation:

Taking two points from the graph to determine the slope

(-3, 4)

(2, -2)

Finding the slope between (-3, 4),(2, -2)

$\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}$ '

$\left(x_1,\:y_1\right)=\left(-3,\:4\right),\:\left(x_2,\:y_2\right)=\left(2,\:-2\right)$

$m=\frac{-2-4}{2-\left(-3\right)}$

$m=-\frac{6}{5}$

Therefore, the slope of the line that joins the points is negative.

i.e m = -6/5

Which best explains what determines whether a number is irrational?

AleksandrR [38]

You can determine if a number is rational if it can be represented as a terminating or repeated decimal, but if it can not, then the number is irrational.

Dafna11 [192]

Answer:

The graph has a closed circle at 10

Step-by-step explanation:

Let

x ----> the number of rentals

The phrase "no more" means "less than or equal to"

The inequality that represent this situation is

$1.50x+10\leq 25$

solve for x

$1.50x\leq 25-10$

$1.50x\leq 10$

$x\leq 10$

The number 10 is included in the solution

therefore

The graph has a closed circle at 10

A quality control engineer is interested in estimating the proportion of defective items coming off a production line. In a samp

fenix001 [56]

Answer:

The lower bound of a 99% C.I for the proportion of defectives = 0.422

Step-by-step explanation:

From the given information:

The point estimate = sample proportion $\hat p$

$\hat p = \dfrac{x}{n}$

$\hat p = \dfrac{55}{100}$

$\hat p$ = 0.55

At Confidence interval of 99%, the level of significance = 1 - 0.99

= 0.01

$Z_{\alpha/2} =Z_{0.01/2} \\ \\ = Z_{0.005} = 2.576$

Then the margin of error $E = Z_{\alpha/2} \times \sqrt{\dfrac{\hat p(1-\hat p)}{n}}$

$E = 2.576 \times \sqrt{\dfrac{0.55(1-0.55)}{100}}$

$E = 2.576 \times \sqrt{\dfrac{0.2475}{100}}$

$E = 2.576 \times0.04975$

E = 0.128156

E ≅ 0.128

At 99% C.I for the population proportion p is: $\hat p - E$

= 0.55 - 0.128

= 0.422

Thus, the lower bound of a 99% C.I for the proportion of defectives = 0.422
