Answer:
The three statements on the right hand side of the screen are the correct ones
Step-by-step explanation:
To take the average of the weight of the cat in the month of April is the following:
9.8 + 9.6 + 9.7 + 9.5 + 9.4 = 48
But then divide that by the number of samples:
48/5=9.6
The mean for April is 9.6
To take the average of the weight of the cat in the month of November is the following:
9.4 + 9.3 + 9.1 + 9.2 + 9 = 46
But then divide that by the number of samples:
46/5=9.2
Then, lastly, subtract the mean from November by the mean of April:
9.6-9.2=0.4
First find the length of the diagonal of a square of side 4 inches:
d^2 = 4^2 + 4^2 = 2*4^2 = 32. Then the diagonal of the cube has length
sqrt( 32 + 4^2) = sqrt(32+16) = sqrt(48) = 4sqrt(3).
Answer:
range = maximum value - minimum value
Step-by-step explanation:
so here..the maximum value is 20 and the minimum value is 7
20-7 is 13=range
1) Open up any parentheses if there are any
2) Combine like terms (moving the variable to one side and other numbers to the other)
3) solve using pemdas/bedmas and any additional steps you need to isolate the variable
4) if x turns out negative, invert the sign
Example:
2x+5=3(x+1)
Open up the parentheses by multiplying it by 3
2x+5=3x+3
Combine like terms
2x-3x=3-5
-x=-2
x=2
I hope this helps!
Answer:
128500
Step-by-step explanation:
This is an arithmetic sequence with a common difference of 3500
The formula for an arithmetic sequence is
an = a1+d(n-1) where a1 is the first term and d is the common difference
an = 48000+ 3500(n-1)
We want n = 24
a24 = 48000+3500(24-1)
= 48000+3500(23)
=48000+80500
=128500
