Answer:
The answer is C
Step-by-step explanation:
Let X and Y be two proportional quantities and let K be constant.
Y=KX so Y/X=K
So for Equation number 1 we have 4y=3x and we will fill it in for 4/3=K
solving to get 1.33...
Now repeat this for the rest to complete the chart
1- 1.33...
2. 1.6
3- 1.33...
4- 0.625
Now we can see that 1 and 3 are the same, so that's how you get your answer, hope this helps!
Since it's 50mL of hardener added in ONE container of resin, you multiply 50 and 15
50mL times 15= 750mL
Hope this helps.
Answer:
15.60 times 100 divided by 390=4%
Step-by-step explanation:
Answer: The maximum error = $105.76.
Step-by-step explanation:
Formula to find the maximum error:
, where n= sample size.
= Population standard deviation
z*= Critical value(two-tailed).
As per given , we have
n= 35
For 98% confidence , the significance level = 
By z-table , the critical value (two -tailed) =
Now , the maximum error = 
Hence, With 98% confidence level , the maximum error = $105.76.
A = LW
A = (< = 33)
L = W + 8
W(W + 8) < = 33
W^2 + 8W < = 33
W^2 + 8W - 33 < = 0
(W + 11)(W - 3) < = 0
W + 11 < = 0
W < = -11 (extraneous solution)
W - 3 < = 0
W < = 3 <===
L < = W + 8
L < = 3 + 8
L < = 11 <===
