Answer:
A manufacturer of banana chips would like to know whether its bag filling machine works correctly at the 447 gram setting.
Mean = 
n = 19
Since n < 30 , so we will use t test
Substitute the values :
t calculated = -0.830
degree of freedom = n-1 = 19-1 = 18
A level of significance=α=0.025
t critical = 2.093
t calculated < t critical
So, We failed to reject null hypothesis
Decision rule -0.830< 2.093 So, We failed to reject null hypothesis
1. Sry, I am confused by this one
2. Positive Integer factors of 196 = 2, 4, 7, 28, 196/2, 2, 7, 7, leaves it with no remainder.
3. Neither
4. Prime
5. Composite
6. 80, 96, 112 (pattern: add 16 each time)
7. 29, 36, 38 (pattern: add 7, add 2 and so on)
Hope this helped!!
Also, can I pls, pls, pls have brainliest? I need about 100 more points and 1 brainliest to lvl up to Ace!!
This is a bit of algebra.. you do not know either side so the width you will label x and the length you will label x +8. we know that if you add all 4 sides, you will have 256 feet. x + x + (x+8) + (x+8)=256 4x+16=256, Subtract 16 from both sides and you have 4x=240. divide by 4 on both sides and you get. x=60.. That makes the width = 60ft and the length = 68ft
The simplified expression of the complex number 6! - 3! is another complex number 6i(1 - 0.5)
<h3>How to simplify the expression?</h3>
The complex number expression is given a:
6! - 3!
Factor out i from the expression
6! - 3! = i(6 - 3)
Factor out 6 from the expression
6! - 3! = 6i(1 - 0.5)
The above means that the simplified expression of the complex number 6! - 3! is 6i(1 - 0.5)
