Answer:
94
Step-by-step explanation:
Average = Total / Number of Data
You have a total of 280 points after 4 quizzes.
4+4=8 quizzes in total
Total you need for average to be 82
Number of points you need to hit required:
You need 376 points in total for the next 4 quizzes.
You need an average of 94 points on the next 4 quizzes.
It Is B.21.8%, Simple way to figure this out is round B to 20%, If 3200 equals 20% and 20% times 5 equals 100% all you do is multiply 3200 by 5.
Step-by-step explanation:
Answer:
Null, H0 : μ = 417
Alternative, H1 : μ ≠ 417
Step-by-step explanation:
Given that :
The mean grams by a bag filling machine μ = 417
Hence, the null hypothesis is That bag filling machine works correctly at 417 grams setting
The alternative hypothesis will negate the null ; In this question, the alternative hypothesis looks at the possibility of either overfill or underfill, which In straightforward terms means that the 417 g ram setting for the bag filling machine is incorrect.
Hence,
Null, H0 : μ = 417
Alternative, H1 : μ ≠ 417
Answer: y = -9x - 9
First, you need to put the two equations into slope intercept form (y=mx+b.)
1) y= -9x + 9
2) y= -10x - 9
First take the slope of #1
m = -9x
Then take the y-intercept of #2
b = -9
Now, put it into an equation.
y = -9x - 9
