Answer:
d=48/2.15
Step-by-step explanation:
hope it helps
easy peazy
1/3 of 30 is 10 because you dividing it by 3 and you would get 10.
Now 2/3 of 10 :
10/3=3.3 (2/3 so we have to multiply by 2) 3.3•2=6.6
6.6 has to be estimated because you can't have 6.6 people.
Your answer would be 6. Before I said 7 but you said I was incorrect so the only possibility left is 6.
Hoped I helped!
Answer:
The correct option is C) 21.1 and 0.68
Step-by-step explanation:
Consider the provided information.
The mean composite score was 21.1 with a standard deviation of 4.8. The ACT composite score ranges from 1 to 36, with higher scores indicating greater achievement in high school.
Therefore μ = 21.1 and σ = 4.8
It is given that the sample of 50 students;
Thus, sample size ( n ) = 50
According to the central limit theorem,
Therefore
Hence, the correct option is C) 21.1 and 0.68
Answer: the angle is 1°+n×120°
1°, 121°, 241°
Step-by-step explanation:
Angles are taken modulo 360°, so 363° = 3°.
Angle plus supplement gives 180°.
Let a be angle, s be supplement of a.
So s = 180-a. Given a = 3 + 2s
a = 3 + 2(180 - a)
a = 3 + 360 - 2a = 363 - 2a
3a = 363° or 3° or 723°
a = 121° or 1° or 241°
a = 1°
s = 179°
2s = 358°
2s+3 = 361° = 1° (modulo 360)
a = 121°
s = 180-121 = 59°
2s = 118°
2s + 3 = 121°, as required.
a = 241°
s = 360+180-241 = 540-241 = 299
2s = 598
2s + 3 = 601 = 241 (modulo 360)
