The 4th equation is the answer
Answer:
Just do 8.4 times 7
Step-by-step explanation:
8.4 times 7 = 58.8
Answer:
C(5,3)=10
Pictures 1,2,3,4,5
So the Possible sets are:
(1,2,3) (1,2,4)
(1,2,5) (1,3,4)
(1,3,5) (1,4,5)
(2,3,4) (2,3,5)
(2,4,5) (3,4,5)
Answer:
x = 5.4
Step-by-step explanation:
(This question has already been answered, but both of the incorrect ones were deleted, so for future reference...)
Fig A is a scale image of Fig D. These two quadrilaterals are similar, and thus, the side lengths of corresponding sides are proportional. Set the proportion x/3 = 7.2/4 (you could alternatively write it as x/7.2 = 3/4 but for the simplicity's sake, and assuming anyone who has this problem would already know how to solve proportions like these...)
7.2/4 = 1.8
so
x/3 = 1.8
now multiply both sides by 3 to get x = 5.4
Answer:
0.430
Step-by-step explanation:
Product has four parts :
For proper functioning, each part must function :
Let the 4 parts be:
A, B, C and D
Proper functioning probability :
A and B = 0.79
C and D = 0.83
For proper functioning :
P(A) * P(B) * P(C) * P(D)
0.79 * 0.79 * 0.83 * 0.83
= 0.42994249
= 0.430
