Evaluate the expression when P=2/3 <br><br>3/4p - 2p<br><br>​
Elan Coil [88]

Answer:

-5/6

Step-by-step explanation:

This is because we can substitute p for 2/3.

(3/4 x 2/3) - (2/1 x 2/3)


This shall equal:

6/12 - 4/3

In order to subtract, we need the same denominator meaning we need that three on 4/3 to be 12. So multiply 4/3 and 4/4

Equation shall be like this:

6/12 - 16/12

Now subtract keep the denominator the same!

-10/12

Simply/reduce (divide by 2/2)

-5/6!!

A researcher surveyed 150 high school students and found that 68% played a musical insturment. What would be a reasonable range
maria [59]

Answer:

The reasonable range for the population mean is (61%, 75%).

Step-by-step explanation:

The interval estimate of a population parameter is an interval of values that consist of the values within which the true value of the parameter lies with a certain probability.

The mean of the sampling distribution of sample proportion is, \hat p.

One of the best interval estimate of population proportion is the 95% confidence interval for proportion,

CI=\hat p \pm z_{\alpha/2}\sqrt{\frac{\hat p(1-\hat p)}{n}}

Given:

n = 150

\hat p = 0.68

The critical value of <em>z</em> for 95% confidence level is:

z_{\alpha/2}=z_{0.05/2}=z_{0.025}=1.96

Compute the 95% confidence interval for proportion as follows:

CI=\hat p \pm z_{\alpha/2}\sqrt{\frac{\hat p(1-\hat p)}{n}}

     =0.68\pm1.96\sqrt{\frac{0.68(1-0.68)}{150}}\\\\=0.68\pm 0.0747\\\\=(0.6053, 0.7547)\\\\\approx (0.61, 0.75)

Thus, the reasonable range for the population mean is (61%, 75%).

X+6/2 - x-8/3 = 5<br><br> HELP PLEASE
Hoochie [10]
(x + 6)/2 - (x - 8)/3 = 5
Multiply each term by 6:-
3(x + 6) - 2(x - 8) = 30
3x + 18 - 2x + 16 = 30
3x - 2x = 30 -18 - 16
x = 30 - 34
x = -4 (answer)
