Good drivers have a quiet level of efficiency in their actions; this derives from a) a good level of attention Ob) accurate observation Oc) both Od) nelther
Answers
Answer:
d. all of the above
Step-by-step explanation:
just took driving course test
Good drivers exhibit a quiet level of efficiency in their actions, which stems from a combination of a good level of attention and accurate observation (option c).
Firstly, a good level of attention means being fully focused and attentive while driving, avoiding distractions, and being aware of the surroundings. This allows drivers to anticipate potential hazards, respond quickly to changing situations, and make informed decisions. Secondly, accurate observation involves keenly observing the road, traffic, and other relevant factors, such as signs, signals, and pedestrians.
By accurately observing their surroundings, good drivers can assess risks, maintain proper positioning, and execute maneuvers with precision. The combination of attention and observation enables drivers to anticipate and respond effectively, promoting safety, efficiency, and smooth execution of actions on the road. The correct option is c.

Researchers investigated whether providing a fancy, foil-wrapped piece of chocolate with the dinner bill would lead to higher tips than not providing such a treat. Sixty-four dinner parties at a restaurant in Ithaca, NY were randomly assigned to receive such a piece of chocolate or not with their dinner bill. Of the 32 parties who received the chocolate, the average tip (as a percentage of the bill) was 17.84%, with a standard deviation of 3.06%. Of the 32 parties who did not receive the chocolate, the average tip (as a percentage of the bill) was 15.06%, with a standard deviation of 1.89%. Determine a 96% confidence interval for the size of the difference in average tips between the two groups
Answers
Answer:
The 96% confidence interval for the size of the difference in average tips between the two groups is (1.47%, 4.09%).
Step-by-step explanation:
Before building the confidence interval, we need to understand the central limit theorem and subtraction of normal variables.
Central Limit Theorem
The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
Subtraction of normal variables:
When we subtract normal variables, the mean is the subtraction of the means while the standard deciation is the square root of the sum of the variances.
Of the 32 parties who received the chocolate, the average tip (as a percentage of the bill) was 17.84%, with a standard deviation of 3.06%.
This means that:
[tex]\mu_{C} = 17.84, s_{C} = \frac{3.06}{\sqrt{32}} = 0.541[/tex]
Of the 32 parties who did not receive the chocolate, the average tip (as a percentage of the bill) was 15.06%, with a standard deviation of 1.89%.
This means that:
[tex]\mu_{NC} = 15.06, s_{NC} = \frac{1.89}{\sqrt{32}} = 0.3341[/tex]
Difference in average tips
The distribution has mean:
[tex]\mu = \mu_{C} - \mu_{NC} = 17.84 - 15.06 = 2.78[/tex]
Standard deviation:
[tex]s = \sqrt{s_{C}^2 + s_{NC}^2} = \sqrt{0.541^2 + 0.3341^2} = 0.6358[/tex]
96% confidence interval
We have that to find our [tex]\alpha[/tex] level, that is the subtraction of 1 by the confidence interval divided by 2. So:
[tex]\alpha = \frac{1 - 0.96}{2} = 0.02[/tex]
Now, we have to find z in the Ztable as such z has a pvalue of [tex]1 - \alpha[/tex].
That is z with a pvalue of [tex]1 - 0.02 = 0.98[/tex], so Z = 2.054.
Now, find the margin of error M as such
[tex]M = zs[/tex]
[tex]M = 2.054*0.6358 = 1.31[/tex]
The lower end of the interval is the sample mean subtracted by M. So it is 2.78% - 1.31% = 1.47%
The upper end of the interval is the sample mean added to M. So it is 2.78% + 1.31% = 4.09%
The 96% confidence interval for the size of the difference in average tips between the two groups is (1.47%, 4.09%).

Step-by-step explanation:
Given
[tex]3x + 2y = 9[/tex]
[tex]3x + y = 0[/tex]
Required
Solve by elimination
To do this, we subtract both equations (to eliminate x)
[tex]3x + 2y = 9[/tex]
- [tex]3x + y = 0[/tex]
--------------------
[tex]3x - 3x + 2y - y = 9-0[/tex]
[tex]y = 9[/tex]
Substitute [tex]y = 9[/tex] in [tex]3x + y = 0[/tex]
[tex]3x + 9 = 0[/tex]
Solve for 3x
[tex]3x =- 9[/tex]
Solve for x
[tex]x = -9/3[/tex]

Step-by-step explanation:
Supplementary angles = 180°
110° + ( 3x + 16° ) = 180
110° + 3x + 16 ° = 180
126° + 3x = 180
3x = 180 - 126
3x = 54°
x = 54/3
