Answer:

-  \frac{1}{2}  =  -  \frac{5}{6}  +  \frac{1}{4} a \\  \\  \frac{1}{4} a =  -  \frac{1}{2}  +  \frac{5}{6}  \\  \\  \frac{1}{4} a =  -  \frac{3}{6}  +  \frac{5}{6}  \\  \\  \frac{1}{4} a =  \frac{2}{6}  \\  \\  \frac{1}{4} a =  \frac{1}{3}   \\  \\ a =  \frac{4}{3}  = 1.33

A sample of 20 joint specimens of a particular type gave a sample mean proportional limit stress of 8.41 mpa and a sample standa
nignag [31]

For this problem, the confidence interval is the one we are looking for. Since the confidence level is not given, we assume that it is 95%.

 

The formula for the confidence interval is: mean ± t (α/2)(n-1) * s √1 + 1/n


Where:

<span>
</span>

α= 5%


α/2 = 2.5%


t 0.025, 19 = 2.093 (check t table)


n = 20


df = n – 1 = 20 – 1 = 19

So plugging in our values:


8.41 ± 2.093 * 0.77 √ 1 + 1/20


= 8.41 ± 2.093 * 0.77 (1.0247)


= 8.41 ± 2.093 * 0.789019


= 8.41 ± 1.65141676

Using the information regarding the proportion of work time linguists study a new language, choose the correct conclusion for th
Vlada [557]

Answer:

The  correct option is  B

Step-by-step explanation:

From the question we are told that

  The null hypothesis is  H_o : p = 0.10

   The alternative hypothesis is  H_a  :  p >  0.10

   The  p-value  is  p-value  =  0.09

   The  level of  significance is  \alpha = 0.025

   

From the given values p-value >  \alpha so we fail to reject the null hypothesis

So there is NOT sufficient evidence to conclude the proportion of work time linguists study a new language is more than 10%.

luna has $50 when she got to the carnival. after 12 rides, she had $26. what was the price of each ride?
stellarik [79]

Answer:

<h2>$2</h2>

Step-by-step explanation:

Lets see how much money she spent first.

$50 - $26 = $24

Now that we know she spent $24 we can divide 24 by twelve which will tell us how much each ride costs

24 / 12 = 2

She spent $2 on each ride
