Answer:
4 i believe
Step-by-step explanation:
Im so sorry if this is wrong and for being late
I will one only and you do the rest.
Let x = -2
Plug into given function.
f(-2) = 2 - 5(-2)
f(-2) = 2 + 10
f(-2) = 12
So, when x = -2, f(x) = 12.
Table:
x............ f(x)
-2 12
-1
0
1
2
Find the rest the same way.
Answer:
No.
Step-by-step explanation:
Let's substitute y=10 on the first equation. -10-52=5 doesn't match
Step-by-step explanation:
L= W+5
P= 9W
P= 2L+ 2W
9W= 2(W+5) + 2W
9W= 2W +10 +2W
9W = 4W +10
5W = 10
W = 2
L=7
P= 9(2)
P= 18
A= LW
A= 7 x 2
A= 14
Answer:
OptionA
Step-by-step explanation:
95% confidence interval is obtained using the following formula
COnfidence interval lower bound = mean - critical value * sigma/sq rt n
and upper bound = mean + critical value*sigma/sq rt n
Thus margin of error = critical value*sigma/rt n
varies indirectly as n provided others are remaining the same.
Hence lower sample indicates higher margin of error
Out of 4 options given we find that I option has maximum margin of error as 21%
Hence option A is most likely coming from a small sample
