You got it correct!
To get from 52 to 13, you divide by 4. And Vis versa, to get from 13 to 52, you multiply by 4. Considering they don't tell you which is the original, the only answer that is either 4 or 1/4 is F
Hope this helps!
Answer:
0 ft < w ≤ 7 ft
Step-by-step explanation:
A=wl, where w, l >0
A≤175 ft²
l= w+18
w(w+18)≤175
w²+18w-175≤0
zeros of are -25 and 7
(w + 25)*(w - 7) ≤ 0
w+25≤0, w-7≥0 ⇒ w ⊂ ∅
w+25≥0, w-7≤0 ⇒ -25 ≤ w ≤ 7,
as w>0, we have answer: 0 < w ≤ 7
Answer:
Step-by-step explanation:
Given that an investigator measuring various characteristics of a large group of athletes found that the correlation between the weight of an athlete and the amount of weight that athlete could lift was 0.60.
Correlation coefficient is the measure of association and a positive value implies that increase in one value causes increase in the other.
Hence out of the given options correct ones are
c) The more an athlete weights, on the average the more he weights.
d) The more an athlete can lift, on the average the more he weighs.
e) 60% of athlete's lifting ability can be attributed to his weight alone.
So assuming L=legnth
xd=y(L-d)
divide both sides by y
(xd)/y=L-d
add d to both sides
((xd)/y)+d=L
