Write an equation and solve it.

Inessa05 [86]

three-fourths minus x = one half

so x equals one-fourth

it will be like this

3 1

-- - x = --

4 2

and i think you gonna have to do keep,change,flip so bascially flip 1/2 then after you multiple and that's how it equaals 1 one-fourth

hope this helps!

As reported in Trends in Television, the proportion of US households who have at least one VCR is 0.535. If 14 households are se

Using the binomial distribution, it is found that there is a 0.5601 = 56.01% probability that the number having at least one VCR is no more than 8 but at least 6.00.

For each household, there are only two possible outcomes. Either it has at least one VCR, or it does not. The probability of a household having at least one VCR is independent of any other household, which means that the binomial distribution is used to solve this question.

Binomial probability distribution

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$

$C_{n,x} = \frac{n!}{x!(n-x)!}$

The parameters are:

x is the number of successes.
n is the number of trials.
p is the probability of a success on a single trial.

In this problem:

14 households, hence $n = 14$ .
0.535 probability of having at least one VCR, hence $p = 0.535$ .

The probability of at least 6 and no more than 8 is:

$P(6 \leq X \leq 8) = P(X = 6) + P(X = 7) + P(X = 8)$

In which:

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$

$P(X = 6) = C_{14,6}.(0.535)^{6}.(0.465)^{8} = 0.1539$

$P(X = 7) = C_{14,7}.(0.535)^{7}.(0.465)^{7} = 0.2024$

$P(X = 8) = C_{14,8}.(0.535)^{8}.(0.465)^{6} = 0.2038$

Then:

$P(6 \leq X \leq 8) = P(X = 6) + P(X = 7) + P(X = 8) = 0.1539 + 0.2024 + 0.2038 = 0.5601$

0.5601 = 56.01% probability that the number having at least one VCR is no more than 8 but at least 6.00.

Order these numbers from least to greatest :

lapo4ka [179]

If you would like to order the following numbers from least to greatest, you can do this using the following steps:

- 40, 1250, - 6.44, 0.2
- 40 < - 6.44 < 0.2 < 1250

The correct result would be - 40 < - 6.44 < 0.2 < 1250.
