Answer:

(x - 8)/4(x - 3).

Step-by-step explanation:

3(x-8)(x+4)/12(x-3)(x+4)

The (x+4) is common to top and bottom of the fraction so we have

3(x - 8)/12(x - 3) 12 = 3*4 so we further simplify:

= (x - 8)/4(x - 3).

SIZIF [17.4K]

Answer: 0.8137

Step-by-step explanation:

As per given , we have

$\mu= 17.2\ ,\ \sigma=2.5$

Sample size : n= 47

Let $\overline{X}$ be the sample mean o.

Then, the probability that the mean of a sample of 47 families will be between 16.6 and 17.6 pounds will be :

$P(16.6$

$=P(-1.645$

[∵ $z= \dfrac{\overline{x}-\mu}{\dfrac{\sigma}{\sqrt{n}}}$ ]

$=P(z$

$=0.8636793-(1- 0.9500151)$ [By using p-value calculator]

$=0.8636793-0.0499849=0.8136944\approx0.8137$

Hence, the probability that the mean of a sample of 47 families will be between 16.6 and 17.6 pounds= 0.8137

an ice cream cone has a height of 16 cm and a diameter of 4 centimeters what is the volume of ice cream that can be contained wi

Iteru [2.4K]

Answer:

67.014

Step-by-step explanation:

V = π r^2 (h/3)

(Volume equals pi r squared, h over 3)

Diameter is 4, so the radius is half of that = 2

Plug in the numbers

V = π (2^2) (16/3)

V = π (4) (5.333)

V = 3.14 x 4 = 12.566

V = 12.566 x 5.333

V = 67.014

The function h(x)=x2+3 and g(x)=x2-6.<br> If g(x)=h(x)+k, what is the value of k?

KiRa [710]

Answer:

-9 =k

Step-by-step explanation:

h(x)=x^2+3 and g(x)=x^2-6

g(x)=h(x)+k

Substitute in

x^2-6 = x^2+3 +k

Subtract x^2 from each side

x^2 -x^2-6 = x^2-x^2+3 +k

-6 = 3+k

Subtract 3 from each side

-6-3 = 3-3+k

-9 =k
