Answer: option D
Step-by-step explanation:
The formulae for standard error = standard deviation/√n
But population standard deviation = 1.8 and sample size = n = 81
Standard error = 1.8/√81 = 1.8/9 = 0.2
Answer:
Down below
Step-by-step explanation:
a. The range of y = sinθ is [-1,1]
b. The period of y = cosθ is 2π
c. The asymptotes of y = tanθ are -π2, π2, πn
d. The amplitude of y = sinθ is 1
e. The period of y = tanθ is π
f. The max value of y = cosθ is 1
Answer:
1/(-3y^3/x)^4
= 1/(-3)^4*(y^3)^4/x^4
= 1/81y^12/x^4
=x^4/81y^12
A
Step-by-step explanation:
اختي هلق اذا نزلنا من الزاوية الثانية خط منحسن نلاقي مستطيل ونحيب مساحته ويلي هية ١٢ متر مربع
بعدين منطلع الضلعين الموجودين يلي لح يكونو نفس القيمة
يعني هوو كمان مستطيل ١٤×٤=٥٦
٥٦+١٢=٦٨
يعني الجواب ٦٨ متر مربع ان شاء الله يكون صح لاني حليته نظرياً
Both are not earning different salaries.
If a study determines the difference in average salary for subpopulations of mechanical engineers and civil engineers is NOT significant, then the subpopulations of mechanical and civil engineers are not earning different salaries.
Study determines that there is not any significant study so thats why both are not earning.
