Answer:
There is no answer. The equation cannot be simplified any further.
L=lintmorepoplation
e=ellmore population
l is 12 times as e
l=12 times e
l=12e
comeined is 9646
l+e=9646
remember that l=12e so subsitue 12e for l
12e+e=9646
add like terms
13e=9646
divide both sdies by 13
e=742
linton=12e
subsitue
linton=12(742)
linton=8904
linton's population is 8904 peple
The correct answer would be option D.
No, it is not a valid inference because his classmates do not make up a random sample of the students in the school
The population represents all of the students in the school. Apart from his science class there can be students in arts class, music class, literature class and so on. He used convenience sampling by just surveying the students of his science class. The students in science class are those who are interested in science and related topics so these students will be more inclined towards watching a science program. Thus the survey of Johnny does not yield valid result and his inference is not valid.
Thus, option D is the correct answer.
Answer:
68
Step-by-step explanation:
You multipliy 7x4 and you get 28 now you add the 40+28=68.
Answer:
x = 2
Step-by-step explanation:
First, let's write out our equation:
I want to isolate x on one side, so first, I'll add 4 to both sides to remove the -4 from next to 2x:
Notice that I combined like terms with the -4 and 4 (to get 0) and the 6 and 4 on the right side (to get 10). Next, I'll add 3x to both sides:
And then I'll add like terms:
Now, all we have to do is divide both sides by 5:
And there's our answer. Hopefully that's helpful! :)
