Answer:
F. Obtuse isosceles
Step-by-step explanation:
Since we have an angle that is 100 degrees, we have an obtuse angle
We have two angles that are 40, which means we have two sides that are equal length, because two angles have the same measure. That means it is isosceles
The triangle is an obtuse isosceles
Answer:
%18 tip
Step-by-step explanation:
The dinner cost was $29 before tip
after tip it was $32.22
34.22-29= $5.22 she tipped
$29 * %x = $5.22
After solving this equation, the x is %18
12 units
(because 0,5 x 12 x 8 = 48)
Answer:
d. None of the above.
Step-by-step explanation:
<em>a. By the law of large numbers, it would again be 46%.
</em>
FALSE. This proportion (46%) is a sample statistic, that can or can not be repeated in another sample.
<em>b. By the law of large numbers, the smaller (second) survey will certainly produce a sample proportion farther from the true population proportion than the larger (first) survey.
</em>
FALSE. Smaller samples will produce wider confidence intervals for the estimation of the population proportion, but larger samples does not necessarily gives us better point estimations of the true proportion. A small sample can be closer to the true proportion than a large sample, although is less probable.
<em>c. The proportion computed from the sample of 5000 people would be more accurate because smaller samples tend to be more homogeneous than larger samples.
</em>
FALSE. There is no evidence to claim that smaller samples are more homogeneous.
<em>d. None of the above.</em> TRUE
Answer:
Option C is the correct choice that is 
Step-by-step explanation:
As this is a multiple choice question we will reduce the options and work on it with the given points 
Note:We know that
where there is
sign associated with it have a straight line graph there is no breaking in the line.
And when there is simply
we have a dashed line when we plot it on a graph.
So option B and D are discarded.
Now one-by one we will put the values
to know which equation it satisfies.
If we put
then
.
So working with option A.

Plugging the values.

And we know that
must be equal to
so this is not the right answer.
We are left with only one choice that is C .
So option C is the correct option of the above inequality.
