In the United States, there were approximately 1,664 ride-related injuries in fixed-site amusement parks in 2007, compared to 1,

797 in 2006. Use an exponential function to determine the ride related injuries in 2016, and discuss the reasonableness of the result.
771; exponential models are useful short-term, but not long-term: not reasonable.

833: reasonable

833; exponential models are useful short-term, but not long-term: not reasonable.

3,880; exponential models are useful short-term, but not long-term: not reasonable.

The decrease in injuries from 2006 and 2007 is a reduction factor of about 7.4%. If we use this factor to predict the number of injuries in 2016, we get 0.926¹⁰=0.463 approx as a reduction factor to be applied to the 2006 data. So 0.463×1797=833 approx. Is this reasonable? I don’t think so because the prediction is based on too few figures. 10 years is fairly long term compared to the short term of a year between 2006 and 2007. To be reasonable data is needed for other years. So answer 3 seems the best answer.

2. Write an equation in slope intercept form with the given Information Goes through points (1, 8) and (5, 0)
pantera1 [17]

Answer:

y = -2x + 10

Step-by-step explanation:

Slope: m = \frac{y_{2}-y_{1}  }{x_{2}-x_{1}}

Slope-Intercept Form: y=mx+b

m=\frac{8-0}{1-5}

m = -2

y = -2x + b

0 = -2 (5)+b

0=(-10)+b

b = 10

y = -2x + 10

Find the equation for the line that passes through the point (−2,0), and that is perpendicular to the line with the equation 2/3
patriot [66]

Answer:

y = 3/2 x + 3

Step-by-step explanation:

2/3 x + y = -14/3

y = -2/3 x − 14/3

The slope of this line is -2/3.  So the perpendicular slope is the opposite of the inverse:

m = -1 / (-2/3)

m = 3/2

We know the slope of the line and a point on the line, so using point-slope form:

y − 0 = 3/2 (x − (-2))

Simplifying into slope-intercept form:

y = 3/2 (x + 2)

y = 3/2 x + 3

A jar contains 4 white and 4 black marbles. We randomly choose 4 marbles. If 2 of them are white and 2 are black, we stop. If no
Airida [17]

Answer:

<em>Find the probability of success in a single trial and then think about the nature of the problem (when do we stop).  </em>

Step-by-step explanation:

Observe that in the single trial, we have (8 4) possibilities of choosing our set of balls. If we have chosen two white balls and two black balls, the probability of doing that is simply  

p=(4 2)*(4 2)/(8 4)

This is well know Hyper geometric distribution. Now, define random variable X that marks the number of trials that have been needed to obtain the right combination (two white and two black balls). From the nature of the problem, observe that X has Geometric distribution with parameter p that has been calculated above. Hence  

P(X = n) = (1— p)^n-1 *( p )

<em>Find the probability of success in a single trial and then think about the nature of the problem (when do we stop).  </em>
