Which expression is equivalent to 6x+8? 2(3x-4) 2(3x+4) 2(4x+6) 2(3x+8)

The answer should be B). 2(3x+4).

We would use the distributive property to multiply 2 by 3x, then again by 4, which gives us 6x+8.

Hope it helped! :)

It is 2(3x+4) because you distribute the 2

Gemiola [76]

Answer:

$z=\frac{0.565 -0.58}{\sqrt{\frac{0.58(1-0.58)}{600}}}=-0.744$

Since is a bilateral test the p value would be given by:

$p_v =2*P(z$

And since the p value is higher than the significance level we have enough evidence to conclude that the true proportion is not significantly different from 0.58

Step-by-step explanation:

Information given

n=600 represent the random sample selcted

X=339 represent the number of females aged 15 and older that living alone

$\hat p=\frac{339}{600}=0.565$ estimated proportion of females aged 15 and older that living alone

$p_o=0.58$ is the value that we want to check

$\alpha=0.01$ represent the significance level

z would represent the statistic

$p_$ represent the p value

Sytem of hypothesis

We want to check if the true proportion females aged 15 and older that living alone is significantly different from 0.58.:

Null hypothesis: $p=0.58$

Alternative hypothesis: $p \neq 0.58$

The statistic is given by:

$z=\frac{\hat p -p_o}{\sqrt{\frac{p_o (1-p_o)}{n}}}$ (1)

Replacing the info given we got:

$z=\frac{0.565 -0.58}{\sqrt{\frac{0.58(1-0.58)}{600}}}=-0.744$

Since is a bilateral test the p value would be given by:

$p_v =2*P(z$

And since the p value is higher than the significance level we have enough evidence to conclude that the true proportion is not significantly different from 0.58

Vinvika [58]

The correlation coefficient for the data in the table was found to be 0.93.

The correct option is A.

<h3>What is the correlation coefficient?</h3>

The correlation coefficient focuses on the linear relationship between two variables.

Given

The first column is labeled time spent at the dentist (in hours) with entries 1.4, 2.7, 0.75, 1.6.

The second column is labeled bill amount (in dollars) with entries 235, 867, 156, 215.

The numbers between -1 and 1 should be one of the values related to the bill.

Taking the independent variable or input variable as, the time a patient spends at the dentist and the dependent variable or output variable as the amount of the bill.

Hence, The correlation coefficient for the data in the table was found to be 0.93.
