Usimov [2.4K]

a) P(3) = \frac{11}{100} (or 0.11 or 11%)

b) Number of sixes = P(6) x 500

                                = \frac{12}{100} x 500

                                = 12 x 5

                                = 60

Linda purchased a used vehicle that depreciates under a straight line method. The initial value of the car is $7000, and the sal
makvit [3.9K]

Answer:

The value at the end of year 2 is $4400.

Step-by-step explanation:

The best approach here is to determine the expression for the line depreciation and then calculate the depreciation value at x = 2 years.

A line is given by

y = mx + b

where m is the slope and b the bias (aka y-intercept).  You can determine both directly from what is given. The slope is change in y divided by change in x. We know that over 5 years the car loses (500-7000)=-6500 in value. So, the slope is m=-6500/5 (note the negative sign). At time 0, the y-intercept is 7000, since that is the initial value (at year 0). So our line function is fully identified:

y = -\frac{6500}{5}x+7000

and gives you the value of the car in any given year. To answer the question, we now plug in 2 as value of x:

y=-\frac{6500}{5}\cdot 2 + 7000= 4400

Answer:

Step-by-step explanation:

diameter=2*radius

=2*9

=18 in

given central angle=72 degree

arc length=central angle /360° *πd

=72/360 *3.14*18

=1/5 *56.52

=56.52/5

=11.304

Complete the general form of the equation of a sinusoidal function having an amplitude of 4, a period of π , and a phase shift t
alex41 [277]

Answer:

4 sin (2x - 4).

Step-by-step explanation:

The amplitude of  sin x = 1 so our curve with amplitude 4 will have 4 sin x as part of the general form. To alter the period from 2pi to pi we multiply the x by 2, giving 4 sin 2x, Finally to get a phase shift of 2 to the right, we replace the x by x - 2.

Our formula is  4 sin (2(x - 2))

= 4 sin (2x - 4).
