Angle 6 and Angle 7 are each 90° since they’re on a straight line and are both equal.
180-90= 90
*you subtract from 180 because that’s how many degrees are in a straight line*
Angle 7 and Angle 1 are alternate exterior angles so that makes them congruent by definition.
5+1.25(8.7)=15,875 $<-----------------
Answer:
36
Step-by-step explanation:
Data provided in the question:
Standard error = 1.5 minutes ( ∵ number are repetitive 1.51.5 )
Standard deviation = 9 minutes ( ∵ number are repetitive 99 )
Now,
Standard error = ( Standard deviation ) ÷ √n
Here,
n is the sample size
Therefore,
on substituting the respective values, we get
1.5 = 9 ÷ √n
or
√n = 9 ÷ 1.5
or
√n = 6
or
n = 6² = 36
The correct answer to this question is (4,-2).
<span>Vertex B of trapezoid ABCD has coordinates (7, −2). It is said that the trapezoid is translated 3 units left. That means that the trapezoid is moved 3 points to the left (at x axis). So 7-3 = 4. This means that the new coordinate of vertex B is (4,-2)</span>
The answer is D! good luck
