Answer:
Both the mean and median and they both gives a measure of 17
Step-by-step explanation:
Given the data about the ages of 7 people :
17,20,22,12,15,12,21
Ordered data: 12, 12, 15, 17, 20, 21, 22
To find the median :
Median = 1/2 * (n+1)th term
n = number of observations = 7
Median = 1/2(7+1)th term
Median = 1/2 *8 = 4th term = 17
Mean = Σx / n = (sum of ages) / number of observations
Mean = 119 / 7 = 17
Answer:
slope = -
Step-by-step explanation:
Differentiating implicitly with respect to x
2x + 2y = 0
2y = - 2x
= - = -
is the measure of the slope of the tangent
rearrange equation to find corresponding y-coordinate of x = - 2
y² = 16 - 4 = 12 = 2 ⇒ y = ± 2
using x = - 2, y = - 2, then
= - = -
Answer:
w = 18
Step-by-step explanation:
6(33 - w) = 90 ( divide both sides by 6 )
33 - w = 15 ( subtract 33 from both sides )
- w = - 18 ( multiply both sides by - 1 )
w = 18
