Answer:
Option I and II
Step-by-step explanation:
I. Assuming this represents a random sample from the population, the sample mean is an unbiased estimator of the population mean.
II. Because they're robust, t procedures are justified in this case.
The t procedures are utilized because they are used as a hypothesis testing tool, which allows for testing of an hypothesis applicable to a population where in this case we are testing the null hypothesis about the population mean.
Correct answer: "Diagonal AC is congruent to itself by the Reflexive Property of Equality."
Insert the sentence above before the sentence "Triangles BCA and DAC are congruent according to the Angle-Side-Angle (ASA)".
The congruence of two angles is already proved, so you need to prove that the corresponding pair of sides is congruent. Then you have 3 pairs of congruent elements for the Angle-Side-Angle (ASA) Theorem.
Answer:
4
Step-by-step explanation:
To find the side length of the original triangle:
24/3=8 (because it is an equilateral triangle).
Because the triangle is dilated by a factor of 0.5 and the triangle is equilateral, the side lengths of the new triangle is
8*0.5=4
Answer: A
Step-by-step explanation:
X times Y = Y times X
The order doesn't matter.
Make a comparison
Plug the numbers into the equation aboveh stands for the height of tree
Do cross multiplication
3.5h = 6 × 18
3.5h = 108
h = 108/3.5
h = 30.8571..
to the nearest hundredth
h = 30.86 feet
to the nearest tenth
h = 30.9 feet
