Hold up i’m trying to help you but
Step-by-step explanation:
(x+2y)²=x²+4xy+4y²

Since 1/6 of the day was spent in the flower bed and 2/3 of that was spreading mulch, we need to find 2/3 of 1/6 to find out how much of the day was spreading the mulch.
In math "of" means times
"is" means equals
2/3 of 1/6 is
translates to
2/3 x 1/6 =
Now we just multiply the numerators across and denominators across then reduce if possible...
2/3 x 1/6 = 2/18
2 and 18 both divide by 2 so it reduces
2/18 = 1/9
Tom spent 1/9 of the day spreading mulch.
Answer:
16
Step-by-step explanation:
So for QR is 1-(-3)=4
QT:|-2-2|=4
TS: |-2-(-2)|=4
RS: 2-(-2)=4
and they plus together is 4x
4x4 = 16
I hope this helps, have a blessed day. :D
Given that the mean is $9.5 and the standard deviation is $1.30, the standard error will be given by:
σ/√n
where
σ-standard deviation
n=sample size
thus, we shal have:
1.30/√20
=0.2906
Next we find the margin error
0.2906*2=0.581
thus the confidence interval will be:
(9.5+0.581, 9.5-0.581)
=(10.081,8.919)
