Answer:
The correct answer is: h(x) = 5 or y = 5
Step-by-step explanation:
h(-2) = 3(-2) + 1
h(x) = -5
y = 5
This is because h(x) is another way of writing Y.

Hope i helped :)
That mean's in total there are 5 tests
5*90 =450 so his total score on the 5 tests should be greater then or equal then 450.
79+94+91+92
356
Let's say x= the last test score
356+x>=450
subtract 356 from both sides
x>=94
The lowest score Sherman can get on his final test is 94.
Answer:
0.3
Step-by-step explanation:
The margin of error is calculated as ...
(standard deviation)/√(sample size) × (z*-score)
where the z*-score is chosen based on the desired confidence level.
Here, you have ...
- standard deviation = 2.7
- √(sample size) = √225 = 15
- z*-score for 90% confidence level = 1.645
Putting these values in the above expression for margin of error gives ...
2.7/15·1.645 = 0.2961 ≈ 0.3
14:1,2,7,14
8:1,2,4,8
The greatest common factor is 2!
