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:
f(x) = 4 · 4^x , f(x) = 4 · 2^x+2 , f(x) = 1/4 · 2^x+6
Step-by-step explanation:
Substitude x with a number.
Please give me Brainliest :)
Answer:
let required no be x
by doing crisscrossed multiplication
42=7x
dividing both side by 7
6=x
therefore x=6
therefore value of remaining no.is 6
