Hi

45 + 89.23568 = 67.09876543456 - ?
First, let's add
134. 23568 = 67.09876543456 - ?
Now let's be smart just for a second :)
We gonna replace this sign ? by x (x means the number we're looking for)
134. 23568 = 67.09876543456 - x
We are solving x, right ? So let's equal it.
Now, we have
-x = 67.09876543456 - 134.23568
You got it ? I hope so :)
Now we subtract
-x = 67.136915
Now we have the number but we can not NEVER left the x with a negative sign, never :)
To eliminate the negative sign we must divide both sides by -1
-x/-1 = 67.136915/-1
x/ = -67. 136915
That's the answer :)

If you have further question about the answer just let me know :)
Thanks !

A binomial experiment has the given number of trials N and the given success probability P.

yan [13]

The probability of the success will be 0.3826.

<h3>What is binomial distribution?</h3>

Bernoulli's trials are those trials which end up randomly either on success (with probability p) or on failures (with probability 1- p = q (say))

The probability that out of n trials, there'd be x successes is given by

$\rm P(x) = \: ^nC_xp^x(1-p)^{n-x}$

We have

n = 8

p = 0.1

q = 1 – 0.1 = 0.9

x = 1

Then we have

P(1) = ⁸C₁ x (0.1)¹ x (0.9)⁷

P(1) = 0.3826

Ebony walked at arate of 3 1/2 miles per hour for 1 1/3 how far did she walk?

ElenaW [278]

let's firstly convert the mixed fractions to improper fractions.

$\bf \stackrel{mixed}{3\frac{1}{2}}\implies \cfrac{3\cdot 2+1}{2}\implies \stackrel{improper}{\cfrac{7}{2}}~\hfill \stackrel{mixed}{1\frac{1}{3}}\implies \cfrac{1\cdot 3+1}{3}\implies \stackrel{improper}{\cfrac{4}{3}} \\\\[-0.35em] \rule{34em}{0.25pt}$

$\bf \begin{array}{ccll} miles&hours\\ \cline{1-2}\\ \frac{7}{2}&1\\[0.8em] m&\frac{4}{3} \end{array}\implies \cfrac{~~\frac{7}{2}~~}{m}=\cfrac{~~1~~}{\frac{4}{3}}\implies \cfrac{7}{2m}=\cfrac{3}{4}\implies 28=6m \\\\\\ \cfrac{28}{6}=m\implies \cfrac{14}{3}=m\implies 4\frac{2}{3}=m$
