Answer:
<u><em>X=1</em></u>
Step-by-step explanation:
1. 1st transformation is translation the parent function 
6 units to the right to get the function 
2. 2nd transformation is reflection the function 
over the x-axis. This transformation gives you the function 
3. 3rd transformation is vertical stretch of the function 
by a factor of 2 to get the function 
Only last two are present in options, then
answer: C and D.
Answer
D. 3m - 4/3 -2/m
<u>Explanation</u>
(9m²-4m-6) ÷ 3m = 9m²/3m - 4m/3m - 6/3m
Carry out the division, each term is divided by 3m.
9m²/3m = 3m
- 4m/3m = -4/3
- 6/3m = - 2/m
Finally you will get,
<em>3m - 4/3 -2/m</em>
4(9) + 3s = 75
36 + 3s = 75
3s = 39
s = 13
Answer:
The margin of error at 90% confidence is 0.5133 gram.
Step-by-step explanation:
Margin of error (E) = (critical value × sample standard deviation) ÷ sqrt(n)
sample standard deviation = 1.5 grams
confidence level = 90% = 0.9
significance level = 1 - C = 1 - 0.9 = 0.1 = 10%
n (sample size) = 25
degree of freedom = n - 1 = 25 - 1 = 24
critical value (t) corresponding to 24 degrees of freedom and 10% significance level is 1.711
E = (1.711×1.5) ÷ sqrt(25) = 2.5665 ÷ 5 = 0.5133 gram
