Drawing conclusions about every woman who leases a car in a particular zip code from a representative sample of 250 women in tha

NemiM [27]

Answer:

The correct answer is :

statistical inference

Step-by-step explanation:

statistical inference is the process of making scientific conclusions and stating truths about parameter on a larger population from existing data gotten from a sample of the population. In this example, only 250 women were sampled, out of the larger total population of the women in the zip code, and due to the data from the findings from these 250 women, a conclusion was drawn that held true for all the women in the zip code. Inference is made based on the laws of probability that allows conclusion to be made on a population from random sampling.

There are different approaches of statistical inference, and these include:

1. Bayesian estimation: here, conclusions are made based on a combination of prior judgments (based on previous studies) and new observations from experimental results.

2. Likelihood approach: here, prior probability results are disregarded and not used, instead, well-understood and advantageous properties of the parameter are used to draw conclusion.

Solve the following equation for x: 9x - 2<br> = 11x + 5

Nady [450]

Answer:

x= $\frac{-7}{2}$

Step-by-step explanation:

9x-2=11x+5

-9x -9x

-2=2x+5

-5 -5

-7=2x

$\frac{-7}{2} = \frac{2x}{2}$

$\frac{-7}{2}$ =x

Arrange the functions in ascending order, starting with the function that eventually has the least value and ending with the fun

nataly862011 [7]

Answer:

Following are the responses to the given question:

Step-by-step explanation:

When x is squared, it's going to be bigger by the conclusion because the larger the faster. $x^2 + 4$ consistently exceeds $4 x^2$ , regardless of the price of X.

5x+3 is always 3 more so than 5x.

In particular, this can be classified according to its pathways $(5x$

$5x\\\\5x + 3\\\\7x\\\\8x + 3\\\\x^2\\\\x^2 + 4$

So can alternatively just say "eventually," which means because when x really is big, you need to find one another's values. Then just select x=100, then plug it into every single other. To confirm this order:

$5(100) = 500\\\\5(100) + 3 = 503\\\\7(100) = 700\\\\8(100) + 3 = 803\\\\(100)^2 = 10,000\\\\(100)^2 + 4 = 10,004\\\\$

So, the ascending order must be the right order!

X - 35 > 15 i need answer IMEDIATLEY

SIZIF [17.4K]

I'm assuming you want us to solve this inequality for x, since the question wasn't too clear on that.

$x - 35 > 15$

Add 35 to both sides to remove the "-35" on the left side so we can isolate the x

$x-35+35>15+35$

$x>50$

The solution to this inequality is x>50. Let me know if you need any clarifications, thanks!

There are 7 Democrats and 6 Republicans on a local city council. A planning committee of 6 for affordable housing needs to be

Brut [27]

Answer:

The probability is $0.383$ .

Step-by-step explanation:

There are 7 democrats and 6 republicans

Number of ways in which 4 democrats and 2 republicans can be selected= ${}^{7}{{C}_{4}}\times {}^{6}{{C}_{2}}$

Number of ways in which 5 democrats and 1 republican can be selected= ${}^{7}{{C}_{5}}\times {}^{6}{{C}_{1}}$

Number of ways in which 6 democrats can be selected = ${}^{7}{{C}_{6}}$

So, favourable outcomes are ${}^{7}{{C}_{4}}\times {}^{6}{{C}_{2}}+{}^{7}{{C}_{5}}\times {}^{6}{{C}_{1}}+{}^{7}{{C}_{6}}$

Total possible outcomes = ${}^{13}{{C}_{6}}$

Now, probability= $\frac{Favourable}{Possible}=\frac{{}^{7}{{C}_{4}}\times {}^{6}{{C}_{2}}+{}^{7}{{C}_{5}}\times {}^{6}{{C}_{1}}+{}^{7}{{C}_{6}}}{{}^{13}{{C}_{6}}}=0.383$
