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)
Answer:
The following are the missing numerators to make the LHS = RHS
46) 36 x³y²
47) 24 (xy)³
48) 5 (3x + 6)
49) 6(3x - 2)
50) 8m (m + n)
Step-by-step explanation:
I have attached how to derive the answer below.
Essentially, each case found what the denominator on the LHS was multiplied by to get to the denominator on the RHS. Then I multiplied the numerator by that same factor.
1.
7x - y = 5
Isolate y
Add y
7x = y + 5
Subtract
y = 7x - 5 2.
5x - 3y = 0
Isolate y
Add y
5x = 3y
Divide
y = 1.66x 3. v=iwh
Isolate w
Divide h
v/h = iw
Divide I
v/hi = w

maybe you coulkd try 5 vecause it works and fits
