Answer:
Step-by-step explanation:
We know by definition that the cosine is an even function, therefore
We also know that the sin is an odd function, therefore
By definition:
Then:
Using these trigonometric properties we can simplify the expression
the answer is c it is circled for you already
Answer:
Step-by-step explanation:
It looks like the solution is the first set of data
{1, 4, 6, 10, 12, 14, 19, 20, 25 }
because: median is 12, Q1 is 6, Q3 is 19, yet the range is from 1 to 25 while the range of the box and whisker plot is 1 to 24.
So theoretically none of those sets represents the box plot.
I think it is c) but when you turn it into a mixed number you get a different number or mixed number if it is not c) it is d)
Hope this helps! T-T
Answer:
228 cm
Step-by-step explanation:
the average is calculated as
average = , then
= 140 ( multiply both sides by 10 to clear the fraction )
sum = 1400
let the height of new pupil be x , then
= 148 ( multiply both sides by 11 )
sum + x = 1628 , that is
1400 + x = 1628 ( subtract 1400 from both sides )
x = 228
height of new pupil is 228 cm
