Answer: The expected frequency for the Business college is 31.5.
Step-by-step explanation:
Since we have given that
Number of students from ABC university = 300
Number of students from Liberal Arts college = 120
Number of students in Education college = 90
Number of students in Business college = 90
Probability of students in Business college = 35% = 0.35
Probability of students in Liberal arts college = 0.35
Probability of students in Education college = 0.30
So, Expected frequency for the Business College is given by
Hence, the expected frequency for the Business college is 31.5.
The others are most likely correct it has been a while since I've worked with fractions
Volume: length*width*height
This problem gives you the three dimensions you need, so…
Multiply: 1 3/4* 1 3/4* 2 1/4
Which equals:
6 57/64 cubic feet
Answer:
a) E(X) = 3.30
b) If these are the only two grades (A and B) available in the school, then this calculated expected value will truly be the expected GPA for each quarter or semester But, if like real life, there are other grades available at the school not included in this calculation, then this value seizes to be the expected value for the GPA over any time period.
Step-by-step explanation:
P(X=xᵢ) = pᵢ
For an A,
P(X=4.0) = 0.3
For a B
P(X=3.0) = 0.7
But E(X) = Σ xᵢpᵢ
E(X) = (0.3 × 4.0) + (0.7 × 3.0) = 3.30
b) If these are the only two grades available in the school, then this calculated expected value will truly be the expected GPA for each quarter or semester But, if like real life, there are other grades available at the school not included in this calculation, then this value seizes to be the expected value for the GPA over any time period.
Answer:
6 cm.
Step-by-step explanation:
Since they've given use the area of the triangle, we can use the area formula to find the base of the triangle.
The formula to find the area of a triangle is:
a= 1/2hb
h = height
b= base
We know:
a=24
h=8
