This is the answer.
Answer: 99(y+9)
Z-score for 30 = (30 - 25) / 5.8 = 0.8621
z-score for 20 = (20 - 25) / 5.8 = -0.8621
:
Note find probabilities from z-tables
:
Probability ( 20 < X < 30 ) = 0.8051 - 0.1949 = 0.6102
, therefore SA = 180 in^2 for a height of 10. So, the correct answer for this proportion task is definitely the second option from the list represented above. b. 180 in2. I am pretty sure it will help you. Regards!
Given that ray AT bisects angle MAR, the measure of angle MAR is 38°.
Hence, option D)38° is the correct answer.
<h3>What is the m∠MAR?</h3>
Given the data in the question;
- Ray AT bisects ∠MAR
- m∠MAT = (4x − 5)°
- m∠RAT = (2x + 7)°
- m∠MAR = ?
Since ray AT bisects ∠MAR, both angle MAT and RAT are equal angles.
Hence,
m∠MAT = m∠RAT
(4x − 5) = (2x + 7)
We solve for x
4x − 5 = 2x + 7
4x - 2x = 7 + 5
2x = 12
x = 12/2
x = 6
Next, we find the numerical value of m∠MAT and m∠RAT.
m∠MAT = (4x − 5)
m∠MAT= 4(6) - 5
m∠MAT= 24 - 5
m∠MAT= 19°
m∠RAT = (2x + 7)
m∠RAT = 2(6) + 7
m∠RAT = 12 + 7
m∠RAT = 19°
m∠MAR = m∠MAT + m∠RAT
m∠MAR = 19° + 19°
m∠MAR = 38°
Given that ray AT bisects angle MAR, the measure of angle MAR is 38°.
Hence, option D)38° is the correct answer.
