Answer:

$110

Step-by-step explanation:

We are looking for the decrease in money per desk purchased. Because the x-axis is the number of desks purchased, what we have to find is the (opposite) of the slope. The formula to represent slope can be written as:

$\frac{y_{2} -y_{1} }{x_{2}- x_{1} }$

We can substitute the points given, (2, 480) and (5, 150) and simplify:

$\frac{150-480}{5-2} =\frac{-330}{3} = -110$

We would multiply by -1 because we are asking for the decrease, and negative increase is decrease. -1 * -110, gives us $110

Answer:

Value of k is $\displaystyle\frac{3}{8}$

Step-by-step explanation:

We are given the following information in the question:

$f(x) = kx^2, 0\leq x \leq 2\\~~~~~~~= 0, \text{ otherwise}$

where x is the time elapses between the end of the hour and the end of the lecture.

We have to find the values of k.

Since, f(x) is the pdf, then,

$\displaystyle\int^\infty_{-\infty} f(x) = 1\\\\\displaystyle\int^2_{0} f(x) = 1\\\\\displaystyle\int^2_{0} kx^2 = 1\\\\k\bigg[\frac{x^3}{3}\bigg]^2_0 = 1\\\\k\times \frac{8}{3} = 1\\\\k = \frac{3}{8}$

Hence, value of k is $\displaystyle\frac{3}{8}$

Probability question!!

Alisiya [41]

Convert both perecentages to decimal form by dividing each of them by 100 to get 0.60 and 0.65. Next, multiply by 0.60 and 0.65 to get 0.39. Multiply the product by 100 to get the percentage form, 39%. So, the answer is 39%.
