Answer:
Option C is the correct choice.
Step by step explanation:
Pedometer is a portable electronic device which counts each step taken by a person. It counts steps by detecting motion of a person's hands and hips.
Pedometers are used by sports enthusiast and physical fitness enthusiasts. Pedometers motivate people to reach their fitness goals as a exercise counter.
Upon looking at our given options we can see that option C represents true characteristic of a pedometer. Therefore, option C is the correct choice.
Answer:
first you have to order the numbers
8, 10, 13, 18, 23, 25, 26, 30
Median is between 18 and 23 so we add them then divide the sum by 2
Median: (18 + 23)/2 = 20.5
First Quartile is between 10 and 13 so we add them then divide the sum by 2
First Quartile: (10 + 13)/2 = 11.5
Third Quartile is between 25 and 26 so we add them then divide the sum by 2
Third quartile: (25 + 26)/2 = 25.5
Range: 30 - 8 = 22
Sorry I don't know how to draw a diagram on brainly
The answer would be C. aroma
Answer:
The answer is -1 or 9
The quadratic equation is ax² + bx + c = 0. But, by completing the square we turn it into: a(x + d)² + e = 0, where:
d = b/2a
e = c - b²/4a
Our quadratic equation is x² - 8x = 9, which is after rearrangement:
x² - 8x - 9 = 0
So, a = 1, b = -8, c = -9
Let's first calculate d and e:
d = b/2a = -8/(2 * 1) = -8/2 = -4
e = c - b²/4a = -9 - (-8)²/(4 * 1) = -9 - 64/4 = -9 - 16 = -25
By completing the square we have:
a(x + d)² + e = 0
1(x + (-4))² + (-25) = 0
(x - 4)² - 25 = 0
(x - 4)² = 25
⇒ x - 4 = √25
Since √25 can be either -5 or +5 , then:
x - 4 = -5 or x - 4 = 5
x = -5 + 4 or x = 5 + 4
x = -1 or x = 9
