Step-by-step explanation:

there are 50 students and 5 prizes (1 + 1 + 3).

so, already in natural language we would say "there is 1 prize for every 10 students".

formally, remember the rule of probability : desired outcomes over total possible outcomes.

this is here

5/50 = 1/10 = 0.1

your can see it also this way :

if there was only 1 prize, each student would have a chance of 1/50 of winning.

now there are 5 prizes, which gives everybody 5 times the chance of winning. which is then 5×1/50 = 5/50 = 0.1

Find the derivative of <br> y = 1/ (3x^3) with steps
Ganezh [65]

Answer:

- 9 {x}^{ - 4}

Step-by-step explanation:

y =  \frac{1}{ {3x}^{3} }  =  {3x}^{ - 3}

y =  <  - 3 \times 3 >  {x}^{ - 3 - 1}  \\  =  - 9 {x}^{ - 4}

Find the indicated limit, if it exists. limit of f of x as x approaches 9 where f of x equals x plus 9 when x is less than 9 and
SVEN [57.7K]

Answer:

B. 18

Step-by-step explanation:

For the function

f(x)=\left\{\begin{array}{l}x+9,\ \ x

we can find the value of the function for all x that are very close to 9 but are less than 9 and for all values of x that are very close to 9 but are greater than 9.

1. For x

\lim \limits_{x\rightarrow 9}f(x)=\lim \limits_{x\rightarrow 9}(x+9)=9+9=18

2. For x\ge 9:

\lim \limits_{x\rightarrow 9}f(x)=\lim \limits_{x\rightarrow 9}(27-x)=27-9=18

So, limit exists and is equal to 18.
