Answer:
The probability is 
Step-by-step explanation:
The total number of students are 200.
number of full timers is 110 and number of part timers is 90.
number of male students is 90 and number of female students is 110.
Let the probability of part timers be P(B).
P(B) = 
= 
Let the probability of female part timers be P(A)
P(A) = 
now, the final probability is
= 
=
Answer:
50 students
Step-by-step explanation:
24% students in a clan were absent in a day .
Hence, the Percentage of students present is calculated as:.
= 100 % - 24 %
= 76%
From the question, we know that:
If 38 students were present ,what is the total strength in the clan
The total strength of the clan = Total number of students. This is calculated as:
76% × x = 38 students.
76/100 × x = 38
76x /100 = 38
Cross Multiply
76x = 38 × 100
x = 3800/76
x = 50 students
Answer:
Step-by-step explanation:
Write the number in exponential form with the base of 2:
Since the bases are the same, set the exponents equals.
Cancel equal terms on both sides of the equation:
Answer:
(23/4, 17/4)
Step-by-step explanation:
The vector from A to B is ...
... V = B - A = (2-7, 5-4) = (-5, 1)
Point P that divides AB the way you want is 1/4 of that from A:
... P = A + (1/4)×V = (7, 4) + (-5/4, 1/4)
... P = (5 3/4, 4 1/4) = (23/4, 17/4)
