Try this solution/explanation:
1. the rule is: m∠TRP=m∠YTR.
2. using the rule described above, it is possible to write the following equation: 3x=2x+35; ⇒ x=35°
Answer: 35°
Answer:
Step-by-step explanation:
31 less then a number x is : x - 31
Answer:
0.9985
Step-by-step explanation:
The population standard deviation is:
s² = 64
s = 8
The sample standard deviation is:
σ = s/√n
σ = 8/√39
σ = 1.28
The z-score is:
z = (x − μ) / σ
z = (128.2 − 132) / 1.28
z = -2.97
The probability is:
P(Z > -2.97) = 1 − P(Z < -2.97)
P(Z > -2.97) = 1 − 0.0015
P(Z > -2.97) = 0.9985

Answer:
0.68?
Step-by-step explanation:
I am not from English speaking country so I am not sure about the first sentence but the second
126n = 86 | /126
n = 86/126
n ≈ 0,68
