Answer:
He should have to spell at least 36 of these words correctly.
Step-by-step explanation:
40 words.
He must spell at least 90% of those words correctly.
At least how many words should he have to spell correctly to get the prize?
90% of 40. So
0.9*40 = 4*9 = 36
He should have to spell at least 36 of these words correctly.
Answer:
So option B is the correct answer .
Step-by-step explanation:
Since it is the multiplication of 1 X 3 matrix to 3 X 3 order matrix,
so the resultant product should be 1 X 3 because when we multiply two matrices it is the condition that if A is of order p X q and B is of order q X r,
the product matrix (suppose C ) will be of order p X r.
so the product will be
= [-1*3+2*2+4*0 -1*6+2*4+4*6 -1*1+2*0+4*2]
= [ 1 26 7] .
-15 - (-3) + 6
-15 - (-3) = -15 + 3 = 3 - 15 = - 12
-12 + 6 = 6 - 12 = -6
Your answer is -6
Answer:
D)
Step-by-step explanation:
It is related to econometrics, however using simple algebraic logic we can solve this problem. General formula with residual is
, where r is a residual. Plugging the pair into the formula, we obtain that
and r=0.5
