Answer:
The answer would be 60 first of all.
Step-by-step explanation:
Ok, this would be an Scalene triangle.
-5x^4 (-3x^2 + 4x - 2) =
15x^6 - 20x^5 + 10x^4
Answer:
3x + 9 = 21
Step-by-step explanation:
Let Henry's age be x
Mary's age = 9 + 3x
21 = 9 + 3x
Can also be written as 3x + 9 = 21
Step-by-step explanation:
a. First, find the z-score.
z = (x − μ) / σ
z = (80 − 74.0) / 12.5
z = 0.48
Use a calculator or table to find the probability.
P(z < 0.48) = 0.6844
b. Find the standard deviation of the sample.
σₓ = σ / √n
σₓ = 12.5 / √4
σₓ = 6.25
Find the z-score.
z = (x − μ) / σ
z = (80 − 74.0) / 6.25
z = 0.96
Use a calculator or table to find the probability.
P(z < 0.96) = 0.8315
c. When the distribution of the population is normal, then the distribution of the sample mean is also normal.
The <em><u>correct answer</u></em> is:
∠LOA ≅ ∠LMA
Explanation:
AAS, or angle-angle-side, states that if two angles and the non-included side of one triangle are congruent to the corresponding two angles and non-included side of a second triangle, then the triangles are congruent.
We have an angle and a side. Out of the remaining two angles, the ones that would make the side marked, LA, non-included are LOA and LMA. This must be the missing information.
