Answer:
Mean speed = 41.3 mph
Step-by-step explanation:
Given that,
The speeds of an automobiles are given below:
20, 35, 42, 52, 65, 49, 24, 37, 23, 41, 50, 58
We need to find the mean speed of the cars.
Mean = sum of observations/ no. of observation
So, the mean speed of the cars is equal to 41.3 mph.
Answer:
x = 0
Step-by-step explanation:
If, in fact, this is the polynomial you have:
, then x = 0.
Begin by distributing the 5/8 into the parenthesis to simplify to:
The next thing to do would be to find the LCM and get rid of all those fractions! Each one of those denominators goes into 24 evenly, so we multiply every single term by 24:
Divide each denominator into 24 and you get:
Multiply all that to get
42x - 20 = 15x - 20
Combine like terms to get
27x = 0 so
x = 0
