Answer:
Step-by-step explanation:
Given that the time to complete a standardized exam is approximately normal with a mean of 70 minutes and a standard deviation of 10 minutes.
P(completing exam before 1 hour)
= P(less than an hour) = P(X<60)
=P(Z<
)
=0.5-0.34=0.16
i.e. 16% of students completed the standardized exam.
Answer:
integers ∪ [0, ∞)
Step-by-step explanation:
The floor function gives the largest integer not greater than the input value. For non-negative numbers, that is the integer portion of the number, as Jim says.
However, for negative numbers, the floor is one less than the integer portion of any number that has a non-zero fractional part.
floor(1.2) = 1
floor(0.2) = 0
floor(-0.2) = -1
floor(-1.2) = -2
For any integer, negative or otherwise, the floor function gives that integer value.
Jim is correct on the domain of all integers and positive non-integers.
Here, 3x-70 = x [ corresponding angles ]
3x-x = 70
2x = 70
x = 35
So, ABC = 3x-70 = 3(35)-70 = 105-70 = 35 degrees
So, your final answer is 35
Answer:
correct
Step-by-step explanation:
She is correct.
For any integer, n, 5n is a multiple of 5.
5n + 3 is 3 more than a multiple of 5.
Start with 82. Subtract 3. Now you have 79.
79 is not a multiple of 5, so 5n + 3 will not contain the term 82.
