Answer:
option (a)
Step-by-step explanation:
Length of long dimension = 11400 km
It means it is the length of major axis.
So, the length of semi major axis = 11400 / 2 = 5700 km
Thus, the length of semi major axis is 5700 km.
Answer: (3x + 4y)(3x + 4y)
Step-by-step explanation: So you are supposed to "unfoil". So you would find two numbers multiplied together to make 9x^2 which would be 3x. Then you would find two numbers that can be multiplied together to get 16y^2 which would be 4y. To check your work, you do 3x times 3x. Then 4y times 4y. Then 4y times 3x plus 3x times 4y. You get 9x^2 + 24xy plus 16y^2.
The sample mean from a group of observations is an estimate of the population mean . Given a sample of size n, consider n independent random variables X1, X2, ..., Xn, each corresponding to one randomly selected observation. Hope this helped:) Have a Great day!
If you count by tens you will be able to find the pattern but if there are single numbers you just add thoses to the count
