Answer:

1.588 * 10^{-1}.

Step-by-step explanation:

Given: 0.1588.

To find : express this number in scientific notation.

Solution : We have given 0.1588.

To express in scientific notation multiply and divide the number by 10

\frac{0.1588 * 10}{10}.

\frac{1.588}{10}.

1.588 * 10^{-1}.

Therefore, 1.588 * 10^{-1}.

Suppose the odds against winning the lottery as 48,000,000 to 1. What is the probability of the event of winning the lottery giv
kupik [55]

The probability according to the given scenario will be "\frac{1}{48,000,001}".

According to the question:

  • The odds against winning the lottery are 48,000,000 to 1.
  • Favorable outcome = 1

→ The total outcome will be:

= 48,000,000 +1

= 48,000,001

As we know,

→ P(E) = \frac{Favorable \ outcomes}{Total \ outcomes}

By putting the values, we get

→           =\frac{1}{48,000,001}

Thus the above response is right.

How do I do this?<br> 4/5x&gt;14
Likurg_2 [28]

Well, first, you need to know what you want to 'do' to it.

You want to find the description of what 'x' has to be in order to
make that inequality a true statement.  Here's one way to do it:

                                              4/5 x > 14

Multiply each side by  5 :     4    x  >  70

Divide each side by  4 :             x  >  17.5 .

That's it.  As long as 'x' is more than 17.5 ,
the original inequality is true.

kiruha [24]

Answer:

No solution

Step-by-step explanation:

We have

$\sum_{x=8}^{4}x^2 + 9\left(\dfrac{\cos^2(\infty)}{\sin^2(\infty)} \right)$

For the sum it is not correct to assume

$\sum_{x=8}^{4}x^2= 8^2 + 7^2+6^2+5^2+4^2 = 64+49+36+25+16 = 190$

Note that for

$\sum_{x=a}^b f(x)$

it is assumed a\leq x \leq b and in your case \nexists x\in\mathbb{Z}: a\leq x\leq b for a>b

In fact, considering a set S we have

$\sum_{x=a}^b (S \cup \varnothing) = \sum_{x=a}^b S + \sum_{x=a}^b \varnothing $ that satisfy S = S \cup \varnothing

This means that, by definition \sum_{x=a}^b \varnothing = 0

Therefore,

$\sum_{x=8}^{4}x^2 = 0$

because the sum is empty.

For

9\left(\dfrac{\cos^2(\infty)}{\sin^2(\infty)} \right)

we have other problems. Actually, this case is really bad.

Note that \cos^2(\infty) has no value. In fact, if we consider for the case

$\lim_{x \to \infty} \cos^2(x)$, the cosine function oscillates between [-1, 1] , and therefore it is undefined. Thus, we cannot evaluate

9\left(\dfrac{\cos^2(\infty)}{\sin^2(\infty)} \right)

and then

$\sum_{x=8}^{4}x^2 + 9\left(\dfrac{\cos^2(\infty)}{\sin^2(\infty)} \right)$

has no solution
