Answer:
the value of x = 10°
Step-by-step explanation:
here's the solution :-
we know that, the measure of exterior angle of the triangle is equal to the sum of opposite two interior angles.
so,
=》5x - 7 + 6x + 14 = 14x - 23
=》11x + 7 = 14x - 23
=》7 + 23 = 14x - 11x
=》3x = 30
=》x = 30 ÷ 3
=》x = 10°
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.
