Answer:
45
Step-by-step explanation:
50% is equal to 0.5
Multiply 90 by 0.5 to get your answer:
90 × 0.5 = 45
Answer:
The angle between them = 52.1°
Step-by-step explanation:
∵ The position vector of the first point is
∵ The position vector of the second point is
∵ The magnitude of the first = √(1²+5²) = √26
∵ The magnitude of the second = √(6²+3²) = √45
∵ The scalar product of them = (1 × 6) + (5 × 3) = 6 + 15 = 21
∵ cosФ = scalar product/(magnitude 1st × magnitude 2nd)
∴ cosФ = 21/(√26 × √45) = 0.61394
∴ Ф = 52.1°
Answer:
The percentage difference between the two methods is 2.95%.
Step-by-step explanation:
The percentage difference is the difference between two values divided by the average of the two values. Shown as a percentage.
The difference means to subtract one value from another and the average is given by
Given
The difference is
The average is
And the percentage difference is
It's a box and whiskers plot, and the rightmost whisker end is the maximum. It goes A: minimum, B: 25th percentile, C: median, D: 75th percentile, E maximum.
Answer: E
