Which of the following linear equations corresponds to the table above?

storchak [24]

Answer:

D) y = 4x + 3

Step-by-step explanation:

<h2>Equation of line in slope y-intercept form:</h2>

$\sf \boxed{\bf y = mx +b}$

Here, m is the slope and b is y intercept.

At y intercept, x = 0

From the table, y intercept = 3

Choose any two points from the table to find the slope.

(0 ,3) & (3,15)

$\sf \boxed{\bf Slope =\dfrac{y_2-y_1}{x_2-x_1}}$

$\sf =\dfrac{15-3}{3-0}\\\\=\dfrac{12}{3}\\\\=4$

m = 4 ; b = 3

Equation of line:

y = 4x + 3

In country A, the vast majority (90%) of companies in the chemical industry are ISO 14001 certified. The ISO 14001 is an inter

yan [13]

Answer: a) 0.74, b) (0.70, 0.778)

Step-by-step explanation:

Since we have given that

Total number of chemical companies n = 500

Number of companies certified = 370

So, $p=\dfrac{370}{500}=0.74$

At 95% level of confidence, z = 1.96

So, interval would be

$p\pm z\sqrt{\dfrac{p(1-p)}{n}}\\\\=0.74\pm 1.96\sqrt{\dfrac{0.74\times 0.26}{500}}\\\\=0.74\pm 0.038\\\\=(0.74-0.038,0.74+0.038)\\\\=(0.70, 0.778)$

Hence, a) 0.74, b) (0.70, 0.778)

Pavel [41]

Let X and Y be random variables representing the side lengths of the rectangle. Then the area of the rectangle is given by the random variable XY.

We have

$\displaystyle P(XY > 0.5) = \int_{0.5}^1 \int_{0.5/y}^1 dx \, dy \\\\ = \int_{0.5}^1 \left(1-\frac1{2y}\right) \, dy \\\\ = \left(1 - \frac12 \ln(1)\right) - \left(\frac12 - \frac12 \ln\left(\frac12\right)\right) \\\\ = \boxed{\frac{1-\ln(2)}2}$

or approximately 0.1534.
