Answer is 506
Slope intercept form is y=mx+b. So let's use the given equation and turn it into this form.

Move the -3x to the right side

Divide both sides by -5

This should be your answer, let me know if you need any clarifications, thanks!
That isnt even a question is a mathematical statement
3x+2 (5x-1)=11
3x +10x -2=11
3x+10x=13
13x=13
X=1
Answer:
c. 9.5 lb < mu < 11.1 lb.
Step-by-step explanation:
Confidence interval can be stated as M±ME where
- M is the sample mean (10.3)
- ME is the margin of error
margin of error (ME) around the mean can be calculated using the formula
ME=
where
- z is the corresponding statistic in 95% confidence level (1.96)
- s is the standard deviation of the sample (2.4)
- N is the sample size (37)
Putting thesenumbers in the formula we get:
ME=
≈ 0.7733 ≈ 0.8
Then the 95% confidence interval would be 10.3 ± 0.8
