Complete Question
In your biology class, your final grade is based on several things: a lab score, scores on two major tests, and your score on the final exam. There are 100 points available for each score. However, the lab score is worth 25% of your total grade, each major test is worth 22:5%, and the final exam is worth 30%. Compute the weighted average for the following scores: 92 on the lab, 81 on the first major test, 93 on the second major test, and 85 on the final exam. (Enter your answer to one decimal place)
Answer:
The weighted average is
Step-by-step explanation:
From the question we are told that
The worth of the lab score is 25% of total grade
The worth of each major test is 22.5% of total grade
The worth of final exam is 30% of total grade
The score on lab is 92
The score on first major test 81
The score on second major test 93
The score on final exam is 85
Generally the weighted score is mathematically represented as

I have no clue I just need to answer some questions before I can ask my own again lol
Answer:
? = 8
Step-by-step explanation:
well
x/44 = 2/11
44 is greater than 11 by 4 times. so to get an equal fraction you need to multiply 2 by 4 to get 8. that way you get 8/44 which would simplify by dividing by 4 to get 2/11
8.47/7=1.21 per lb. 11.07/9=1.23 so $8.47 for 7lbs. is cheaper than 11.07 for 9lbs.
You need to multiply another number each time.
For Example:
3x2=6
6x3=18
18x4=72
72x5=360
360x6= 2,160
It's a pattern
