Answer:
hello : P = - 6 and Q = 35
Step-by-step explanation:
Px + 35=-6x + Q
calculate : x
Px + 6x = Q - 35
(P+6) x = Q - 35
this equation have infinitely many solutions if : P+6 = 0 and Q - 35 =0
P = - 6 and Q = 35...( values of P and Q)
Answer:
erm
Step-by-step explanation:
4.41 times 10^-1
Answer:
Step-by-step explanation:
a). Mean of the given data set = 
= 28
b). x

32 32-28 = 4 16
28 28 - 28 = 0 0
18 18 - 28 = -10 100
40 40 - 28 = 12 144
22 22 - 28 = -6 36
= 296
c). Standard deviation = 
= 
= 7.69
d). Mean of the new set of weights = 
= 34
Since mean of the data set is more close to each data, standard deviation will be less than the deviation given in part (c).
Answer:
The reciprocal of 16 is 1/16
Step-by-step explanation:
The reasoning for this is that the reciprocal of any number is the opposite of it.
Another example would be: The reciprocal of 1/2 would be 2/1
