The answer is D) 72, 108
First you have to find out the measure of the two other angles in the triangle. Those two angles will be equivalent.
Because the sum of all three angles in a triangle is 180, you subtract 36 from it (180 - 36 = 144) then divide by 2 (144/2 = 72).
So, the two angles at the bottom of the triangle are each 72. Because those angles are supplementary to the angles at the top of the trapezoid, you subtract 72 from 180 (180 - 72 = 108).
108 + 108 = 216
The sum of all the angles in a trapezoid is 360, so subtract 216 from 360 (360 - 216 = 144) then divide by 2 (144/2 = 72)
We know that
In French club <span>there are
10 freshman
</span><span>12 sophomores
15 juniors
30 seniors
total of the members------> (10+12+15+30)=67
total </span> freshman-----> 10
so
<span>the probability that a freshman will be chosen=10/67
and
</span><span>the probability that a freshman will not be chosen=(67-10)/67
</span>the probability that a freshman will not be chosen=57/67---> 0.8507
0.8507= 85.07%
the answer is
the probability that a freshman will not be chosen is 85.07%
Answer:
This would most probably result in biased sample since only a specific part of the community is being surveyed that does not represent all of the community.
Step-by-step explanation:
A survey is being conducted to determine how a city's residents feel about building a new youth center.
They are considering to survey 50 random children at a local elementary school.
This would most probably result in biased sample since only a specific part of the community is being surveyed that does not represent all of the community.
Moreover, it is likely that the students of elementary school might not even have any interest in youth center so results would be biased.
Therefore, it is suggested to include a variety of samples that is surveying different age groups that covers all of the community.
Answer:
I'm 98% sure its c. 1/4
Step-by-step explanation:
in order for a line to be parallel to another they have to be on different y intercepts but have the same slope causing them to never intersect.
the slope of the graph on the line is 1/4 because of rise over run
You can use the slope formula y2-y1/x2-x1 to find slope, the answer is D
