Whats the equation...............
Hi We can’t work that out until u tell us how many candles there actually WERE
16x + 9 = 9y -2x
<u> -16x -16x</u>
9 = 9y -18x
<u>-9y -9y
</u> -9y + 9 = -18x
<u> - 9 -9 </u><u>
</u> - 9y = -18x -9 (divide each side by -9)
y = 2x + 1
Answer:
1.66
Step-by-step explanation:
The mean of a set of data is 4.68 and its standard deviation is 2.83. Find the z score for a value of 9.38
Given that :
Mean (m) = 4.68
Standard deviation (s) = 2.83
Value of x = 9.38
Zscore = (x - mean) / standard deviation
Zscore = (9.38 - 4.68) / 2.83
Zscore = 4.7 / 2.83
Zscore = 1.6607773
Hence, Zscore for a value of 9.38 is 1.66
