Answer:
(a) 350
(b) 175
(c) 21
(d) 196
Step-by-step explanation:
Number of females = 7
Number of males = 5
Total ways of selecting r items from n items is
(a)
Total ways of selecting 3 females and 2 males.
(b)
Total ways of selecting 4 females and 1 male.
(c)
Total ways of selecting 5 females.
(d)
Total ways of selecting at least 4 females.
Total ways = 4 females + 5 females
Answer:
ii. 55 degrees.
Step-by-step explanation:
(ii)
Consider the quadrilateral ABCD.
Angle n = 180 - 96 = 84 degrees ( opposite angles of a cyclic quadrilateral are supplementary).
Consider triangle ABC: the 3 angles are supplementary, so
m < j = 180 - 84 - 41
= 55 degrees.
Question says that there are two type of pans.
First pan has diameter of 9 inches.
Second pan has dimension 8 inches by 11 inches. Which means second pan is rectangular.
It seems you missed few parts of the question like what we have to do with it. I searched for similar question on internet and found that they are finding surface area of the both pans so i will tell you how to find that.
Radius of the circular pan = diameter/2 = 9/2 = 4.5 inches
Then surface area of the first (circular) pan = \pi r^2 = 3.14 *4.5^2 = 63.585 square inches.
Now surface area of second (rectangular) pan is given by formula of area of rectangle
Area = Length * width = 8*11= 88 square inches.
It would be at least 70 yph I am probably sure
