Answer:

Step-by-step explanation:
We are given the following in the question:
The organizers estimate that the variation in distance flown by the athletes will be σ = 10 meters.
This will be stated by the null hypothesis.

It was claimed that the organizers are underestimating the variation and the variation in distance is greater than 10.
This will be stated by the alternate hypothesis.

The parameter for the given hypothesis is standard deviation,
.
Formula for a square is s^2.
(8x-1)^2=
(8x-1)(8x-1)=
64x-8x-8x+1=
64x-16x+1=
48x+1
Therefore, the area of the square mentioned in the question is 48x+1.
Answer:
6 green fish
Step-by-step explanation:
green fish = x
(X+3)/60 = x/40
Cross multiplication
60x = 40x+120
subtract 40x on both sides
20x = 120
Divide both sides by 20
x=6
The aquarium has 3 more yellow fish than green fish 6+3 = 9 (9 yelow)
15 fish in total
