You have decided to buy a new car, but you are concerned about the value of the car depreciating over time. You do some research
____ [38]
<span>The answer should be set up like so: 

3125 = 3200*(d)^3 
3125/3200 = d^3 
3-root (3125/3200) = d 
d = 0.992125657... 

1 - d = 0.007874... 
Therefore it depreciates at about 0.8% monthly 

To find the depreciation 6 months from now, or 9 months from the beginning: 
v = 3200 (d)^9 
= 2980.232239... 

So after 9 months the car would be about $2980.23</span><span>

Identify the zeros of f(x) = (x + 9)(x − 4)(6x + 1).
slavikrds [6]
<h2>The required 'option a)  - 9 , \dfrac{-1}{6}, 4' is correct.</h2>

Step-by-step explanation:

We have,

f(x) = (x + 9)(x − 4)(6x + 1)

To find, all zeroes of the given equation = ?

∴ f(x) = (x + 9)(x − 4)(6x + 1)

⇒ (x + 9)(x − 4)(6x + 1) = 0

⇒ x + 9 = 0 or, x − 4 = 0 or, 6x + 1 = 0

⇒ x + 9 = 0 ⇒  x = - 9

⇒ x − 4 = 0 ⇒ x = 4

⇒ 6x + 1 = 0

⇒ 6x = - 1

⇒ x = \dfrac{-1}{6}

∴ x = - 9 , \dfrac{-1}{6}, 4

Thus, the required 'option a)  - 9 , \dfrac{-1}{6}, 4' is correct.

The Acme Company manufactures widgets. The distribution of widget weights is bell-shaped. The widget weights have a mean of 44 o
Cerrena [4.2K]

Answer:

a) No 95% of values will fall between (24;64); 68,27% will fall between (34;54)

b)71,83 % will fall between 34 and 64 ounces

Step-by-step explanation:

Empirical rule establishes, for a  normal distribution with mean μ and σ as standard deviation:

In interval   μ  ±  σ    or   ( μ  +  σ ;  μ  -  σ) we should find 68.27 % of all values of the population, and by simmetry 68.27/2 = 34,14 % should be over the mean and the other half would  be values below the mean

Therefore in our case

μ  +  σ  =  44 + 10  =  54

And

μ  -  σ  = 44 - 10   = 34

a) Then  68,34 % of values will fall in this interval

We know now that value 34 is 1* σ   below the mean, and is at the limit of 34,14 %

b) μ  +  2*σ  =   44 * 2*10  =  44 + 20  =  64

64 is the upper limit for the interval   μ  +  2*σ  and we know that 95.45 % of all values will fall between (  μ  -  2*σ  ;  μ  +  2*σ ) and by simmetry just one side of this interval (the right side ) will have 95.45/2 = 47;73 %

Then in interval going from ( 34 ; 64 ) we shoud find 47.73 + 34,14

71,83 % of all values will fall between 34 and 64
