Answer:
see explanation
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
here m = 4 and (a, b) = (- 3, 7), hence
y - 7 = 4(x - (- 3)), that is
y - 7 = 4(x + 3) ← second equation in the list
What is the median of the data set? <br><br>
{16, 15, 17, 19, 12, 11, 14, 14, 13, 11, 18, 15}
RUDIKE [14]
The median is the numeric value separating the higher half of a sample data set from the lower half. The median of a data set can be found by arranging all the values from lowest to highest value and picking the one in the middle. If there is an odd number of data values then the median will be the value in the middle. If there is an even number of data values the median is the mean of the two data values in the middle.
For the data set 16, 15, 17, 19, 12, 11, 14, 14, 13, 11, 18, 15 the median is 14.5. It is the mean of 14 and 15 or, (14+15)/2 = 14.5.
Answer:
The x-intercept is (18/5, 0).
The y-intercept is (0,-2).
Step-by-step explanation:
To find the <u>x-intercept</u>, sub y for 0.
-5x + 9y = -18
-5x + 9(0) = -18
Simplify and isolate x.
-5x = -18 <= Divide both sides by -5
x = 18/5
Since we substituted y for 0, y=0.
(18/5, 0)
To find the <u>y-intercept</u>, sub x for 0.
-5x + 9y = -18
-5(0) + 9y = -18
Simplify and isolate y.
9y = -18 <= Divide both sides by 9
y = -2
Since we substituted x for 0, x=0.
(0,-2)
the mean can be misleading, because there outlier (77), which is not close to the ages of the others, thereby changing the mean drastically.
hope this helps
