(9, 15) since when you multiply them by 3 both values are equivalent.
Answer:
b. ordinal
Step-by-step explanation:
Letter grade (A, B, C, D, F) are Ordinal in nature. This is because they are indicators that is used to describe and demonstrate the arrangement of collection,ordering of performance in a sequential manner, one after another.
Another fact which makes the level of measurement to be Ordinal is due to the fact that the array of the objects ( Letter grade (A, B, C, D, F) )also align in terms of magnitude.
Answer:
Midpoint for A is (1,5) and for B it is (2.5,4.5)
Step-by-step explanation:
To get the midpoint you add the x coordinates and divide by 2 and then the y coordinates and divide by 2.
X = (3 + -1)/2 y = (8+ 2)/2
=2/2 = 1 10/2=5
Answer:
C. 3 and 4
Step-by-step explanation:
The squares nearest to 12 are ...
3² = 9
(√12)² = 12
4² = 16
Then something whose square is 12 will be between 3 and 4.
Let X be the number of defective transistors. Let p be the probability that defective transistor.
P(defective transistor) = 0.04
P(non defective ) = 1- 0.04 = 0.96
A random sample of size 30 is tested for defects and we want to find probability of no defective transistor
P(No defective transistor) = P(X= 0)
Here X follows binomial distribution with parameters n=30 and p=0.04
The Binomial probability function with parameters n and p is
P(X=x) =
P(X=0) =
Using n=30 and p=0.04
P(X=0) =
P(X=0) = 1*1*(0.96)^30
P(X=0) = 0.2938
The probability that there are no defective transistors in the sample is 0.2938
