Answer:
1.5
Step-by-step explanation:
this is because 24 divided by 16 equals 1.5
Answer:
Raul did better in biology test relative to the rest of the class.
Step-by-step explanation:
We are given two situations;
- Raul received a score of 75 on a history test for which the class mean was 70 with a standard deviation of 8.
- He received a score of 80 on a biology test for which the class mean was 70 with standard deviation 5.
Now, we have to find on which test did he do better relative to the rest of the class. For this we will calculate z score for both the situations;
The z score value is given by, Z = 
; where, 
= mean
= standard deviation
For 1st situation; z score = 
= 0.625
For 2nd situation; z score = 
= 2
So, it is clear that 2nd situation is better as it has higher z score.
Therefore, Raul did better in biology test relative to the rest of the class.
Step-by-step explanation:
if there is no typo, then that is
y = 1 + 5 = 6
y = 6
has no term in x.
that means 6 is the constant result of the line function, no matter what x value we pick.
and that means this is a horizontal line (parallel to the x-axis) going through the point y=6 or (0, 6).
remember that the slope is the ratio "y coordinate change / x coordinate change".
but y is not changing at all, the change or difference is always 0 no matter what points we pick on the line.
and so, the slope ratio is always "0/...". and that is 0.
so, the slope of that line is 0.
but if there is a typo, then please know : the slope of a line
y =ax + b
is always a (the factor of x).
Answer:
1
Explanation:
According to the Unit Circle, sin π\6 is ½, so we plug this into the cosine function to get this:
cos π\6 - π\6 → cos 0 >> 1

*** Plus, we need to make sure that the x-value falls in between 0 and π\2, which it did, so no need to worry.
