Answer:
28.26
Step-by-step explanation:
The circumference of a circle is the distance around the edge of the circle. To find the circumference, we use the formula C = 2πr. The area of the circle is the amount inside the circle and is found using A = πr². Substitute the relevant values in each situation into the formulas to find the circumference and/or area.
Substitute C = 18.84 and solve for r. Then substitute r into the area formula.
C = 2πr
18.84 = 2πr
3 = r
A = πr² = π(3)² = 28.26
Answer:
5) a) complementary
6) b) supplementary
7) c) vertical angles
Step-by-step explanation:
5)
The sum of the complementary angles = 90 degrees
According to the graph, both angles add up to 90 degrees
Answer: a) complementary
6)
Straight angle is equal 180 degrees
The sum of the supplementary angles = 180 degrees
Answer: b) supplementary
7)
Vertical Angles are the angles opposite each other when two lines cross. The vertical angles are congruent.
Answer: c) vertical angles
Answer:
-53/12
Step-by-step explanation:
convert mixed nukber to improper fraction
-23/3+(-5 1/2)+8 3/4
-23/3-5 1/2+8 3/4
-23/3-5 1/2+35/4
-23/3-11/2+35/4
-53/12
Answer:
d. May result in the TSLS being inconsistent in large samples
Step-by-step explanation:
Two-stage least squares (TSLS), regression analysis is a statistical technique that is used for two distinct stages of variables regression, so, when there are more relevant instruments than required, is like having a larger sample size in that the more information is available for use in the Instrumental Variables regression (IV).
Answer:
1/4096
Step-by-step explanation:
A negative exponent becomes a fraction. 4*3=12. 2^12=4096, so since it's a negative exponent you put it as a fraction. So it's 1/4096.
