Answer:
x = 52/9
Step-by-step explanation:
The exterior angle is half the difference of the intercepted arcs, so we have ...
9x -5 = (158 -64)/2
9x = 52 . . . . . . . . . . . add 5
x = 52/9 = 5 7/9
Answer:
81000
or 8.1
Step-by-step explanation:
1m = 100cm
10m = 1000cm
a= b*h
a= 1000cm * 810cm
= 810000
1
= 10000
810000
= 8.1
Answer:
68%
Step-by-step explanation:
The mean is 32 minutes, and the standard deviation is 4 minutes.
28 is 1 standard deviation below the mean, and 36 is 1 standard deviation above the mean.
According to the empirical rule, 68% of a normal distribution is between -1 and 1 standard deviations. 95% is between -2 and 2 standard deviations. 99.5% is between -3 and 3 standard deviations.
So the answer is 68%.
