Answer:
70%
Step-by-step explanation:
Out of 7+3 = 10 total hours Samuel logged on Thursday, 7 were spent with clients. The fraction of hours spent with clients was ...
client hours / total hours = 7/10
Multiplying by 100% converts that to a percentage:
Thursday client time = 7/10 × 100% = 70%
Answer:
no enough evidence to draw up a conclusion
Step-by-step explanation:
Data:
let: 
= decay after 2 weeks
= decay after 16 weeks
Making the hypotheses:
Null hypothesis; 
the deviation = 0.05
the standard difference = 4
Conditions:
The normal distribution curve can be plotted on a graph and the plot shows that the distribution is a skewed distribution.
Then,
Therefore, it can be concluded that 0.1983 > 0.05. This presents our failure to reject the null hypothesis.
Thus, there is not enough evidence to conclude that polyester decays more in less than 2 weeks.
4*1/2=2

Answer:
the anwser you put is correct
Step-by-step explanation:
congragulations! glad i could help :)
Let us solve this system of equations by using the elimination method. Adding the 2 equations, we get
9x + 5y - 9x + 4y = -33 + 6
9y = -27
y = -3
Substituting this value of y in the first equation, we get
-9x + 4(-3) = 6
-9x - 12 = 6
9x + 12 = -6
9x = -18
x = -2
Therefore, x = -2, and y = -3. Hope this helps! If you have any questions, feel free to ask.
