Answer:

Step-by-step explanation:

$f(x)=2x+6\\\\f(x+1)-\text{substitute}\ x+1\ \text{instead of x}:\\\\f(x+1)=2(x+1)+6\qquad\text{use the distributive property}\\\\f(x+1)=2x+2+6\qquad\text{combine like terms}\\\\f(x+1)=2x+8$

There are twelve signs of the zodiac. How many people must be present for there to be at least a 50% chance that two or more of

Nutka1998 [239]

Answer:

Step-by-step explanation:

Given that each zodiac sign occupies 1/12 of a year.

Then the minimum number of persons for Y[all different signs] < 0.5,

The probability of at least two having the same sign is 1 minus the probability of all having different signs.

This can be represented as A [at least 2 person share the same sign] = 1 - Y[all different signs] must be > 0.5

Therefore we have 1 - 12/12 *11/12 * 10/12 *9/12 *8/12 = 0.38

This implies that the lowest number will be found to be 5

Hence, the correct answer is 5.

1.what is the volume of the small cone in terms of pi

svp [43]

Step-by-step explanation:

<u>Step 1: Find the radius of the big cone</u>

$\frac{radius_1}{height_1} = \frac{radius_2}{height_2}$

$\frac{2}{5}=\frac{x}{10}$

$2(10)=5(x)$

$20/ 5=5x / 5$

$4=x$

<u>Step 2: Find the volume of the small cone</u>

$V = \frac{\pi*r^2*h} {3}$

$V = \frac{\pi * 2^2 * 5}{3}$

$V = \frac{20\pi}{3}\ units^3$ ← Volume of Small Cone

<u>Step 3: Find the volume of the large cone</u>

<u /> $V = \frac{\pi*r^2*h} {3}$

$V=\frac{\pi*4^2*10}{3}$

$V = \frac{160\pi}{3}\ units^3$ ← Volume of Large Cone
