To find the mid segment, it is half of the sum of the bases
for number 13 it's 7+13=20 20/2=10
number 14 it's 12+9=21 21/2=10.5
number 15 it's 22+18=40 40/2=20

If avogadro's number of pennies is divided equally among the 250. million men, women, and children in the united states, how man
Anastasy [175]

We divide the pennies 100 to convert pennies to dollar

1 pennies= 1/100 dollar

Then we will convert 6.02×10∧23 p to dollar

=1 dollar/100 pennie ×6.02×10∧23

= 6.02×10∧21

The total men and women and children in 250 m  

=25×108

6.02×10∧21/2.5×10∧8

= 2.408×10∧13

A researcher is interested in determining the mean energy consumption of a new
Nana76 [90]

Answer:

The most appropriate  value of the critical value is 2.289.

Step-by-step explanation:

We are given that a researcher takes a random sample of 41 bulbs and determines  that the mean consumption is 1.3 watts per hour with a standard deviation of 0.7.

We have to find that when constructing a 97% confidence interval, which would be the most appropriate  value of the critical value.

Firstly, as we know that the test statistics that would be used here is t-test statistics because we don't know about the population standard deviation.

So, for finding the critical value we will look for t table at (41 - 1 = 40) degrees of freedom at the level of significance will be \frac{1 - 0.97}{2} = 0.015 .

Now, as we can see that in the t table the critical values for P = 1.5% are not given, so we will interpolate between P = 2.5% and P = 1%, i.e;

     \frac{0.015 - 0.025}{0.025-0.01}= \frac{\text{Critcal value}-2.021}{2.021-2.423}

So, the critical value at a 1.5% significance level is 2.289.
