Answer:

$\frac{16}{3}$

Step-by-step explanation:

To evaluate substitute x = - $\frac{1}{2}$ into f(x)

f( - $\frac{1}{2}$ )

= - $\frac{2}{3}$ × - $\frac{1}{2}$ + 5

= $\frac{1}{3}$ + 5

= $\frac{1}{3}$ + $\frac{15}{3}$ = $\frac{16}{3}$

A researcher works on a study that has a population standard deviation of 0.73a sample mean of 84.5 and a sample size of 60 .Wha

Firlakuza [10]

Answer:

$ME = z_{\alpha/2} \frac{\sigma}{\sqrt{n}}$

The critical value can be founded in the normal standard distribution table using the value of $\alpha/2 =0.025$ and we got $z_{\alpha/2}=1.96$ . Replacing the info given we got:

$ME = 1.96 \frac{0.73}{\sqrt{60}}= 0.185$

Step-by-step explanation:

For this case we have the following info given:

$\sigma = 0.73$ represent the population deviation

$\bar X = 84.5$ represent the sample mean

$n =60$ represent the sample size

And we want to find the margin of error for a confidence level of 95%. So then the significance level would be $\alpha=1-0.95 = 0.05$ and $\alpha/2 =0.025$ . The margin of error is given by:

$ME = z_{\alpha/2} \frac{\sigma}{\sqrt{n}}$

The critical value can be founded in the normal standard distribution table using the value of $\alpha/2 =0.025$ and we got $z_{\alpha/2}=1.96$ . Replacing the info given we got:

$ME = 1.96 \frac{0.73}{\sqrt{60}}= 0.185$

Emie bought 3 12-packs of regular cola, 4 12-packs of diet cola, and 2 6-packs of orange soda. How many cans did he buy?

Yanka [14]

96 in total since 3 times 12 equals 36. Then you have 4 times 12 which equals 48. Also you have 2 times 6 equals 12. THEN you add it together to get 96.
