Answer:

f (x) = -2 (x + 6)^2 + 2

Step-by-step explanation:

f (x) = -2x^2 - 24x - 70 <--- divide out -2 out of the first two terms...

f (x) = -2 (x^2 + 12x) - 70 <-- divide the x coefficient by 2 and then square it, then add AND subtract it)  

f (x) = -2 (x^2 + 12x + (12/2)^2 - (12/2)^2) - 70  

f (x) = -2 (x^2 + 12x + 36 - 36) - 70 <--- distribute the -2 onto -36 to get it out of the brackets..  

f (x) = -2 (x^2 + 12x + 36) + 72 - 70 <-- combine constants and factor perfect square trinomial...  

f (x) = -2 (x + 6)^2 + 2 <-- standard form...

V=(π)(r^2)(h)

π=3
r=half of the diameter=4
h=12

V=(3)(4^2)(12)
    = (3)(16)(12)
        = 576 cm cubed

Weights were recorded for all nurses at a particular hospital, the mean weight for an individual nurse was 135 lbs. with a stand
Aloiza [94]
Given:
population mean, &mu; =135
population standard deviation, &sigma; = 15
sample size, n = 19

Assume a large population, say > 100,
we can reasonably assume a normal distribution, and a relatively small sample.
The use of the generally simpler formula is justified.

Estimate of sample mean
\bar{x}=\mu=135

Estimate of sample standard deviation
\s=\sqrt{\frac{\sigma^2}{n}}
=\sqrt{\frac{15^2}{19}}=3.44124  to 5 decimal places.

Thus, using the normal probability table,
P(125
=P(\frac{125-135}{3.44124}
=P(-2.90593
=P(Z
=P(Z

Therefore 
The probability that the mean weight is between 125 and 130 lbs 
P(125<X<130)=0.0731166-0.0018308
=0.0712858

If a phone cost $224 what would it cost if there was a 7% sales tax.
Annette [7]

Answer:

<u>$239.68</u>

Step-by-step explanation:

<u>Given</u>

  • Cost = $224
  • Sales Tax = 7%

<u>Solving</u>

  • Cost w/ Tax = Cost (1 + Tax)
  • Cost w/ Tax = 224 (1 + 0.07)
  • Cost w/ Tax = 224 * 1.07
  • Cost w/ Tax = <u>$239.68</u>
