Answer: mean=26 , median=24
Step-by-step explanation:
Mean=Sum of all values/number of values
mean= 30+39+24+ 19+18/5
= 130/5
mean=26
Median
arrange data in order
18,19,24,20,39
In the case of ungrouped odd-numbered data, the number that divided data into 2 equal parts is called the median.
so median=24
<span>s = 60t - 3t^2
v = ds/dt = 60 - 6t
when it comes to rest, v = 0,
so t = 10 sec
now distance travelled = time taken x average velocity
= 10 x (60 + 0)/2
= 300 ft

Answer:
x < 4
Step-by-step explanation:
We have that: 1 + 2x < 9. Let's solve this as if the < sign was an = sign:
1 + 2x < 9
Isolate the variable:
2x < 9 - 1
2x < 8
Divide by 2:
x < 8/2
x < 4
The answer is x < 4.
If you would like to solve for the positive value of x, you can do this using the following steps:
6 * x^2 - 54 = 0 /6
x^2 - 9 = 0
(x - 3) * (x + 3) = 0
1. x = 3
2. x = - 3
The correct result would be x = 3.
