Answer:
2+1.12x=10 minus 2 on each side 1.12x = 8 divide 1.12 to each side is 7.14 miles rounded up on the tenth place
Answer:
= 2(1 - 2h)
Step-by-step explanation:
Given that:
=3(2−0.9h)+(−1.3h−4)
Simplifying:
=(6 - 2.7h) + (-1.3h - 4)
Removing brackets
=6 - 2.7h -1.3h - 4
Adding like terms (h terms and constants)
= 2 - 4h
We can take 2 common as:
= 2(1 - 2h) Required sum
I hope it will help you!
Answer:
No, Mr. Hernandez’s sample is random, not biased, large enough compared to the population, but 28 is not 20% of 90.
Step-by-step explanation:
At Lawson Middle School, Mr. Hernandez asked 90 randomly selected students from each grade level for their favorite subject.
90 randomly selected students from each grade level for their favorite subject, and 28 chose social studies as their favorite.
so, the percent of students who love social studies is given by:
28/90 x 100=31.11%
He used this data to draw the inference that out of the 250 middle school students, about 20% prefer social studies.
No, Mr. Hernandez’s sample is random, not biased, large enough compared to the population, but 28 is not 20% of 90.
