Answer:
Step-by-step explanation:
<u><em>The picture of the question in the attached figure</em></u>
The point P is the center of the circle (the drawing is not a scale )
step 1
Find the measure of angle ∠CPD
we know that
---> by supplementary angles (form a linear pair)
step 2
Find the measure of arc DC
we know that
<u><em>Central angle</em></u> is the angle that has its vertex in the center of the circumference and the sides are radii of it
so
----> by central angle
therefore
Answer:
The probability the student studies Art and
Biology is 0.2143.
Step-by-step explanation:
Denote the events as follows:
A = a students studies Art
B= a students studies Biology
The information provided is:
N = 42
n (An B) = 9
n (A' n B) = 10
n (A' n B') =7
Then the number of students who study Art
but not Biology is:
n(An B') = N -n (An B) -n (A' nB) - n (A'n B')
= 42 - 10 - 7 - 9
= 16
The number of students who study Art but
not Biology is 16.
Compute the probability the student studies
Art and Biology as follows:
P(ANB)
n(ANB)
= 0.2143
Thus, the probability the student studies Art
and Biology is 0.2143.
Answer:
Following are the solution to this question:
Step-by-step explanation:
Just Parts (c) were discussed because they were mentioned in the issue.
A subpart of (c):
In point (i)
The answer is 1 for the CES since only CES has salary and wage rates information.
In point (ii)
The answer is 2 for the CPS because only the CPS has job status information.
In point (iii)
The answer is 3 for the CPS as detailed in this issue, neither CES nor CPS explicitly states gender information. Even so, population studies generally include a 'gender' requirement.
Answer:
Area of rectangles: l*b [LENGHT×BREADTH]
Therefore,
3/4 × 2/3 = Area
We do it as, 3*2/4*3
⇒ 6/12 = area
After simplification, we will get
1/2 = area of rectangular picture
