Answer:
234 cm²
Step-by-step explanation:
Given expression to represent the surface area of the rectangular prism is 
The given value of x is 3.
Now, finding value of expression by sustituting value of "x" as given.
Surface area of the rectangular prism = 
Surface area of the rectangular prism= 
∴ Surface area of the rectangular prism= 
Surface area of the rectangular prism= 
∴ Surface area of the rectangular prism= 234 cm²
The slope should be 3/2, since you rise 3 and go over 2
Answer:
A.
Step-by-step explanation:
6^(1-1) + 6^(2-1) + 6^(3-1) + 6^(4-1)
= 1 + 6 + 36 + 216
= 259.
Answer:
335 = 50 + 6p
Step-by-step explanation:
50 +6p=335
subtract from both sides
-50 -50
6p=285
/6p /6p
divide both sides
p=47.5
Answer:
Step-by-step explanation:
We are given the following in the question:
The needle size should not be too big and too small.
The diameter of the needle should be 1.65 mm.
We design the null and the alternate hypothesis

Sample size, n = 35
Sample mean,
= 1.64 mm
Sample standard deviation, s = 0.07 mm
Type I error:
- It is the error of rejecting the null hypothesis when it is true.
- It is also known as false positive error.
- It is the rejecting of a true null hypothesis.
Thus, type I error in this study would mean we reject the null hypothesis that the average diameter is 1.65 mm but actually the average diameters of the needle is 1.65 mm.
Thus, average diameter is 1.65 mm and we decide that it is not 1.65 mm.
