You pick 5 digits (0-9) at random without replacement, and write them in the order picked. What is the probability that you have
Tanzania [10]

Answer:

Probability is : 1/30240= 0.000033068

Step-by-step explanation:

You pick 5 digits (0-9) at random without replacement, and write them in the order picked.

The probability that you have written the first 5 digits of your phone number is -

As there are no repeats, the choice to choose from decreases at each step making it 10,9,8,7,6.

(1/10)(1/9)(1/8)(1/7)(1/6)=1/30240= 0.000033068

A log splitter can split 6/5 cords of wood in 4/5 of an hour. Complete the unit rate by setting up a complex fraction and simpli
Digiron [165]

Answer:

1½ cords per hour

Step-by-step explanation:

A log splitter can split 6/5 cords of wood in 4/5 of an hour.

To find a unit rate, we divide the quantity of cords of wood by the time.

This gives us the complex fraction.

\frac{ \frac{6}{5} }{ \frac{4}{5} }

This is the same as

\frac{6}{5}  \div  \frac{4}{5}

To divide two fractions, we multiply by the reciprocal of the second fraction.

\frac{6}{5}   \times   \frac{5}{4}

\frac{3}{1}   \times   \frac{1}{2}

This simplifies to:

\frac{3}{2}  = 1 \frac{1}{2}

The unit rate is 1.5 cords per hour

Differentiate y= ln (6 – 3x)^4​
dsp73

Step-by-step explanation:

\frac{dy}{dx}  =  \frac{1}{ {(6 - 3x)}^{4} }  \times  {4(6 - 3x)}^{3} ( - 3) \\  =   \frac{ - 12 {(6 - 3x)}^{3} }{ {(6 - 3x)}^{4} }   \\  =  -  \frac{12}{6 - 3x}

I hope I'm correct. I've never learnt differentiation for log and exponents before
