Answer:
Step-by-step explanation:
M = (35 + 40 + 12 + 16 + 25 + 10)/5
M = 138/5
M = 27.6
Answer:
Step-by-step explanation:
The ratio of adult to children is determined by number of adult / number of children.
We want to determine the three ratios that are equivalent to 2 adults 5 children. So we will divide each of the given number of adults and children.
1) 8 adults 20 children = 8/20 = 2/5
2) 5 adults 8 children = 5/8
3) 20 adults 50 children = 20/50 = 2/5
4) 4 adults 10 children = 4/10 = 2/5
So the three ratios that are equivalent to 2 adults 5 children are
8 adults 20 children,
20 adults 50 children and
4 adults 10 children
Answer:
4r^3+8r^2-5r-10
= 4r^2(r+2)-5(r+2) [Factorise out like terms; distributive law of multiplication to check]
=(4r^2-5)(r+2) [Combine expressions]
Answer:
The correct answer to the following question will be "0.0367".
Step-by-step explanation:
The given values are:



As we know,


On putting the given values in the above expression, we get


Now, consider
![P(p1-p2>0.03)=P[\frac{(p1-p2)-E(p1-p2)}{SE(p1-p2)}>\frac{0.03-0}{0.0168}]](https://tex.z-dn.net/?f=P%28p1-p2%3E0.03%29%3DP%5B%5Cfrac%7B%28p1-p2%29-E%28p1-p2%29%7D%7BSE%28p1-p2%29%7D%3E%5Cfrac%7B0.03-0%7D%7B0.0168%7D%5D)



Therefore, "0.0367" is the right answer.
