Answer:

48

Step-by-step explanation:

There are 40 trials, 16 out of those 40 trials resulted in two heads and one tail, which is what we are trying to find out of 120..

To do that, find 16/40 which gives you 0.4%

Next multiply 0.4% by 120 and you will get 48.

How do you find the derivative of 1/logx?
valentina_108 [34]

The derivative of 1/logx is With the chain rule.

1log(x)=log(x)−1 is ,= -1xlog(x)2 .

The by-product of logₐ x (log x with base a) is 1/(x ln a). Here, the thrilling issue is that we have "ln" withinside the by-product of "log x". Note that "ln" is referred to as the logarithm (or) it's miles a logarithm with base "e".

The by-product of 1/log x is -1/x(log x)^2. Note that 1/logx is the reciprocal of log.

With the chain rule. \\ 1log(x)=log(x)−1  \\ So you follow the chain rule to the electricity after which to the log: \\ ddxlog(x)−1=−1⋅log(x) \\  \\−2⋅ddxlog(x)  \\ =−1log(x)21x  \\ =−1xlog(x)2 .

Answer:

D 6

Step-by-step explanation:

Normally when I multiply mixed numbers, I change them to improper fractions first so that it is easier.

1\frac{2}{10} × 5 = \frac{12}{10} × 5

Multiply 5 by the numerator of the fraction and leave the denominator alone.

\frac{12}{10} × 5 = \frac{60}{10}

Change back to simplest form.

\frac{60}{10} = 6
