6 students have black hair, 3 students have blonde hair, and 21 students have brown hair. since percentages come out of 100% you can use ten as a smaller size, so 20% of 10 is 1, multiply that by three because our full percentage is out of 30, and you get 3, and so on.
y = -4x - 1
It is a linear function different from the constant function. Therefore, if the range is only one number, then the domain is only one number too.
Let's calculate it:
y = -25 → -4x - 1 = -25 |add 1 to both sides
-4x = -24 |divide both sides by (-4)
x = 6
Answer: The domain = {6}.
Answer:
x = - 2
Step-by-step explanation:
y = 4 is the equation of a horizontal line parallel to the x- axis.
Thus a perpendicular line will be vertical and parallel to the y- axis.
The equation of a vertical line is
x = c
where c is the value of the x- coordinates the line passes through.
The line passes through (- 2, 1) with x- coordinate - 2, thus
x = - 2 ← equation of perpendicular line
Answer:
sin A = 56/ 65
Step-by-step explanation:
sin of an angle = opposite side to the angle / hypothenuse
sin A = 56/ 65
The <em>correct answer</em> is:
A single outlier causes the value of the median to move slightly toward the outlier.
Explanation:
Overall, outliers have very little effect on the median. However, they do affect it some.
If the outlier is a very large number, the median will slightly increase as compared to the data set without the outlier.
If the outlier is very small, the median will slightly decrease compared to the data set without the outlier.
In both instances, the median is moved slightly towards the outlier.
