Answer:
3,36 in^2
Step-by-step explanation:
The geometric shape shown in image is called a trapezoid
to calculate the area of a trapezoid we use the following formula:
1/2*(a+b)*h (a and b are bases, h: height)
bases are 1.3 and 3.5 and height is 1.4
1/2(1.3 + 3.5)*(1.4) = 3,36 the area is stated in square units so the answer is
3,36 in^2
Here’s the correct answer and how it got it :)
Answer:
7%
Step-by-step explanation:
Answer:
A manufacturer of banana chips would like to know whether its bag filling machine works correctly at the 447.0 gram setting.
So, Null hypothesis : 
It is believed that the machine is under filling the bags
So, Alternate hypothesis : 
n = 41
Population standard deviation = 
x = 443
We will use z test since n > 30 and we are given the population standard deviation.
Formula : 


Use z table to find p value
p value = 0.1131
α = 0.02
p value > α
So, we fail to reject null hypothesis.
So, its bag filling machine works correctly at the 447.0 gram setting.
(p>64) divided by 4 is less than or equal to w
