Answer:
30
Step-by-step explanation:
(n+8)=2(7+8)=2(15)=30
Order them from smallest to largest:
21, 24, 25, 26, 26, 31
mean: 25.5
add all the numbers up and divide them by 6.
median: 25.5
the number in between 25 & 26.
mode: 26
there are two 26’s in the pattern.
range: 21-31
5 x 10^5 = 500,000
2 x 10^5 = 200,000
The scientific notation 5 x 10^5 is 2.5 times greater than the scientific notation of 2 x 10^5.
Answer:
b. continuous random variable
Step-by-step explanation:
Speed is a common continuous variable and the value is always random.
It is continuous because there is always another speed value between two speed values. For example, a car travelling at the rate of 50 mils per hour will either increase or decrease its speed at a continuous rate. No speed can drop suddenly form 50mph to 20mph.
It is random because although there might be speed limit, the speed recorded by the Highway patrol officer willl always be random in value.
That is the distance between each pair points
