Answer:its a zero slope or you can do x2-x1 and y2-y1 and if its an even fraction try simplifying it .
Step-by-step explanation:
Answer:
0.2288
Step-by-step explanation:
This is straightforward.
What we need to do is to divide the number of defective semiconductor chips over the total number of semiconductor chips.
Initially, the total number of semi conductor chips is 119 and the total number of defective semiconductor chips is 28.
After the first selections , we can infer that the total number of semiconductor chips is 118 while the number of defective ones is 27.
Hence on the second drawing, the probability that he will
Select a defective one is 27/118
Answer:
<u>The</u><u> </u><u>requ</u><u>ired</u><u> </u><u>num</u><u>ber</u><u> is</u><u> </u><u>7</u><u>0</u><u>.</u>
Step-by-step explanation:
let the no. be 10y + x where x is unit digit and y is ten's digit.
given , sum of the digit is 7
x + y = 7 ...(1)
also , reversing the no. we get 10x + y ,where x is ten's digit and y is unit digit.
given reversed digit decreases the number by 63 .
so, 10y + x - ( 10x + y ) = 63
9y -9x = 63
( dividing both side by 9 )
y - x = 7 ....(2)
adding 1 and 2 [ refer attachment ]
so the required original number is
10y + x = 10×7+0 = 70
