Answer:
Ratio of Wood MS to Parker MS = 81 : 131
Step-by-step explanation:
Given
number of students at WMS = 136+188 = 324
number of students at PMS = 316+208 = 524
Ratio of students
WMS : PMS = 324 : 524 = 81 : 131
Answer:
Option (D).
Step-by-step explanation:
If the graph of a relation has two output values for a single input value, relation will not be considered to be a function.
Option (A).
For the input values of x = -1, there are two output values, y = -1, 1.
Therefore, given relation is not a function.
Option (B).
Since, all the parabolas don't represent a function, given parabola in the graph is not a function.
Option (C).
Not a function. It's a relation.
Option (D).
Line plotted in the graph has a distinct output value for every input value.
Therefore, the given graph represents a linear function.
D. Use the formula V=πr^2 h.
<h2>
Answer: ( 2 , -2 )</h2>
Step-by-step explanation:
Mid-point = [ ((x₁ + x₂) ÷ 2) , ((y₁ + y₂) ÷ 2) ]
= [ (6 + (-2)) ÷ 2] , [(1 + (-5)) ÷ 2]
= ( 2 , -2 )
Answer:
The probability that the control chart would exhibit lack of control by at least the third point plotted is P=0.948.
Step-by-step explanation:
We consider "lack of control by at least the third point plotted" if at least one of the three first points is over the UCL or under the LCL.
The probability of one point of being over UCL=104 is:

The probability of one point of being under LCL=96 is:

Then, the probability of exhibit lack of control is:

The probability of having at least one point out of control in the first three points is:

The probability that the control chart would exhibit lack of control by at least the third point plotted is P=0.948.
