He is not making a valid inference because he is assuming the student populations interest based on a small part/ group of the student population, his class.
Hi
I used another place to type my answer because I don't think Brainly has all the tools I need.
I hope this finally help and I am sorry for my laziness :)
As always, I am here to help!
Speed = Distance/Time
So, speed
= 300 km/2h
= 150km/h
= (150 × 1000m) / 3600s
= 150000m/3600s
= 41.66m/s [approximately]
The larger the sample size, the smaller the standard error; therefore, the width of a confidence interval <u>decreases</u> as the sample size increases.
Answer:
10
Step-by-step explanation:
to find the answer for 3y + 4 we have to find the value of y.
we can find that by using the second equation.
-2y+6=2
-2y+6-2 =0 (subtract 2 from both the sided)
4= 2y (we will bring the -2y to the other side of the equation and then subtract the 6-2 to get the 4)
4/2=y (divide by 2 on both the sides)
∴ y=2
now we will plug in the y of value that we see as -2 into the first equation.
∴ 3y+4 will become
= 3(2)+4
=6+4
=10
hope this helps!!
