Solution
1) Divide both sides by <span>11
</span>n=88÷11
2) Simplify 88÷<span>11</span> to 8
<span>n=8
ANSWER = 8 </span>
If the function is exponential, then (2x) is the exponent.
f(x) = a^(2x)
Take it from here.
Answer:
1019/minutes
Step-by-step explanation:
$94.33 - $23 = $71.33
$71.33 ÷ 0.07 = 1019/mins
I hope this helps...
Answer:
So then the minimum sample to ensure the condition given is n= 38
Step-by-step explanation:
Notation
represent the sample mean for the sample
population mean (variable of interest)
represent the population standard deviation
n represent the sample size
ME = 4 the margin of error desired
Solution to the problem
When we create a confidence interval for the mean the margin of error is given by this formula:
(a)
And on this case we have that ME =4 and we are interested in order to find the value of n, if we solve n from equation (a) we got:
(b)
The critical value for 96% of confidence interval now can be founded using the normal distribution. The significance is
. And in excel we can use this formula to find it:"=-NORM.INV(0.02;0;1)", and we got
, replacing into formula (b) we got:
So then the minimum sample to ensure the condition given is n= 38
