Function:
f(x) = 2 cos x +1
Note: The values of x should be given in radians.
Therefore;
Substituting for x = 1.5 radians
f(1.5) = 2 Cos 1.5 + 1 ≈ 1.1415
Answer : option A
To find the range of scores that represents the middle 50 % of the student who took the test , we find inter quartile
Inter quartile range is the middle 50% of the given range of scores.
The difference between the upper quartile and lower quartile is the inter quartile that is middle 50%
From the diagram , we can see that
Upper quartile = 89
lower quartile = 65
So range is 65% to 89%
Answer:
$9.12
Step-by-step explanation:
Decimal places are:
0.0 --> Tenths
0.00 --> Hundredths
0.000 --> Thousandths
etc.
Therefore we need to round the decimal to 2 decimal places...
9.123 --> 9.12 (The number rounds down if the number after it is between 1 and 4 and it rounds up if the number after it is between 5 and 9. In this scenario the number after it is "3" therefore it rounds down)
The plane would be 100 feet long. if the scale is 1/100 and the model is 1 ft you would take 1 x 100 to get 100 feet.
19.99+12.49=32.48
19.99 for the movie and 12.49 for the earphones together they make 32.48
