F(x)= 6x-4
f(x)=6*8-4
f(x)=48-4
f(x)=44
Answer:
50%
Step-by-step explanation:
10 of the pins were green
there are 20 pins in total
10/20 of the fries are green
10/20=1/2=50/100
50/100=50%
Answer:
The 95% CI for the difference of means is:

Step-by-step explanation:
<em>The question is incomplete:</em>
<em>"Find a 95% confidence interval on the difference of the towels mean absorbency produced by the two processes. Assumed that the standard deviations are estimated from the data. Round to two decimals places."</em>
Process 1:
- Sample size: 10
- Mean: 200
- S.D.: 15
Process 2:
- Sample size: 4
- Mean: 300
- S.D.: 50
The difference of the sample means is:

The standard deviation can be estimated as:

The degrees of freedom are:

The t-value for a 95% confidence interval and 12 degrees of freedom is t=±2.179.
Then, the confidence interval can be written as:

It is a nonlinear I hope this helps
Yes it looks like it would be right
