Answer: ( -6 , -6.5 )
Step-by-step explanation:
The formula for calculating Mid - point is given by
M = (
,
)
= -5
= -7
= -9
= -4
substituting into the formula , we have
M =
, 
M =
, 
Therefore : mid point = ( -6 , -6.5 )
15-3b=63
subtract 15 from both sides
-3b=48
divide -3 from both sides
b= -16
Answer:
A
Step-by-step explanation:
b is the range
Answer:
Permutation is used.
No. of arrangements = 1260
Step-by-step explanation:
Permutation is used for choosing & arrangement of 'r' out of 'n' objects, when sequence is important.
Total no. of alphabets in CORRECT = 7
C is repeated twice, R is repeated twice
So, Total No. of arrangements = <u>7 !</u>
(2!)(2!)
= 5040 / 4
= 1260
Surface area of a cone = π{rs+r²}<br /> =πr{s+r}<br />part 1:if π is 6 units and s is 4 units then r would be 3.14 ×6 {4+6}<br /><br />part 2: area of a cone = 3.14 ×6×10<br /> =31.4×6<br /> = 188.4 units²<br />the surface area = 188.4 <br />units²<br /> hope i helped
