Answer: 86 points

Step-by-step explanation:

I used cross multiplication. Debbie scored 28% of the points, which could be written as 28/100. I set 28 over 100 equal to 24 over x. The x represents the total amount of points, with the 24 over it to show that Debbie got 24 points out of the total. To solve, I did 100 times 24, and then divided that by 28. Once you do that, you get 85.7, so I round up to the nearest whole number which is 86.

Answer:

A is correct, x=7, AB=20

Step-by-step explanation:

All of the options say x=7 so you can just input 7 into 4x-8 to find AB

4(7)-8=AB

28-8=AB

20=AB

Hope this helps, please mark brainliest :)

Sonja [21]

Answer:

Step-by-step explanation:

Given that;

Compressed Soil 2.85 2.66 3 2.82 2.76 2.81 2.78 3.08 2.94 2.86 3.08 2.82 2.78 2.98 3.00 2.78 2.96 2.90 3.18 3.16

Intermediate Soil 3.17 3.37 3.1 3.40 3.38 3.14 3.18 3.26 2.96 3.02 3.54 3.36 3.18 3.12 3.86 2.92 3.46 3.44 3.62 4.26

                            Compressed soil           intermediate soil

Mean                      2.907                              3.286

SD                          0.1414                              0.2377

Here we have,

\bar x_1 =3.286\\ \bar x_2 =2.907\\s_1 =0.2377\\ s_2 =0.1414\\n_1=19\\n_2=20

The pooled Standard deviation

s_p=\sqrt{\frac{(n_1-1)s_1^2(n_2-1)s_2^2}{n_1+n_2-2} } \\\\=0.1943

So standard error for difference in population mean is

s_{\bar x_1 - \bar x_2} = \sqrt{\frac{s_p^2}{n_1}+\frac{s_p^2}{n_2}  } \\\\=0.0623

by inputting the values we get 0.0623

Degree of freedom for t is

df = 19 + 20 - 2 = 37,

so t-critical value is 2.715.

So required confidence interval for

\mu_{1} - \mu_{2} will be

( \bar x_1 - \bar x_2) \pm t_{critical}*s_{\bar x_1 - \bar x_2}

=0.3793 \pm2.715*0.063\\\\=0.3793\pm0.1690

So required confidence interval is (0.2103 , 0.5483).
