Answer:
0.83
Step-by-step explanation:
0.1 + 0.73 = 0.10 + 0.73 = 0.83
Answer:
Step-by-step explanation:
Both angles are supplementary (they add up to 180°)
This means that (10x) + (6x - 12°) = 180°
(10x) + (6x - 12°) = 180°
10x + 6x - 12° = 180°
16x - 12° = 180°
16x = 192°
x = 12°
Hope this helps!
The empirical rule states that at 95% the measurements would be within 2 standard deviations of the mean.
You are given a mean of 68 inches and a standard deviation of 4.
2 times the standard deviation = 2 x 4 = 8
So 95% of the heights would be between 68-8 = 60 inches and 68+8 = 76 inches.
Answer:
8/45m² +2/35m
Step-by-step explanation:
if you want to see how just look for multiplication of fractions
Let m and r represent the maximum speeds of Malcolm and Ravi in km/h, respectively.
... (m + r)/2 = 260 . . . . . the average of their speeds was 260 kph
... 2m = r + 80 . . . . . . . . double Malcolm's speed is 80 kph more than Ravi's
The second equation can be solved for r and that expression substituted into the first equation.
... 2m - 80 = r . . . . . . . . . . . an expression for r from the second equation
... (m + 2m - 80)/2 = 260 . . . the result of substituting that into the first
... 3m - 80 = 520 . . . . . . . . multiply by 2
... m = 200 . . . . . . . . . . . . . add 80 and divide by 3
... 2·200 - 80 = r = 320 . . .substitute the value of m into the expression for r
Malcolm's maximum speed was 200 km/h.
Ravi's maximum speed was 320 km/h.
