Step-by-step explanation:
given length of hypotenuse, h=3 units.
adjascent angle for x is 45°
cos(45°)=x/3
cos(45°)=1/root 2(I dont have root symbol sorry)
1/root 2=x/3
x=3/root 2 units
x=3root 2/2
and hi pls comment
Answer:
4
Step-by-step explanation:
90 percent is 9/10 of total possible
x = total possible points
x * 9/10 = 36
x = 36 * (10/9) = 4 * 10 = 40
40 - 36 = 4
Prime numbers are: 37, 47, 19,
Composite numbers are: 9, 15, 26, 33, 45
18, because cats would be 3, and then the dogs would be 6 times that, which would be 18. 18 + 3 = 21.
Answer:
99.85%
Step-by-step explanation:
Most of today's student calculators have probability distribution functions built in. Here we are to find the area under the standard normal curve between 58 mph and 76 mph, if the mean speed is 67 mph and the std. dev. is 3 mph.
Here's what I'd type into my calculator:
normalcdf(58, 76, 67, 3)
The result obtained in this manner was 0.9985.
This states that 99.85% of the vehicles clocked were traveling at speeds between 58 mph and 76 mph.
