help me do this i’m confused!! thank you!!

Answer:

Upper Control Limit = 6.03 oz

Lower Control Limit = 5.97 oz

Step-by-step explanation:

Given - A process that makes chocolate candy bars has an output that is normally distributed with a mean of 6 oz. and a standard deviation of .01 oz.

To find - Determine three sigma control limits for an x-bar (mean) chart assuming a sample size of 10.

Proof -

Given that,

μ = 6

σ = 0.01

Z value for 3 sigma process = 3

Now,

Control limits are - μ ± Zσ

Now,

Upper Control limit (UCL) = μ + Zσ

And

Lower Control limit (LCL) = μ - Zσ

Now,

UCL = 6 + 3( 0.01 )

        = 6 + 0.03

       = 6.03

⇒UCL =6.03 oz

Now,

LCL = 6 - 3( 0.01)

      = 6 - (0.03)

      = 6 - 0.03

      = 5.97

⇒LCL =5.97 oz

∴ we get

Upper Control Limit = 6.03 oz

Lower Control Limit = 5.97 oz

Cities in which the mean is based on a smaller number of drivers will have greater variation in their means and are therefore more likely to be both safest and least safe.

In statistics, a simple random sample is a subset of individuals chosen from a larger set in which a subset of individuals are chosen randomly, all with the same probability. It is a process of selecting a sample in a random way.

Given that, from among the 300 largest cities in the United States, the FleeceU Auto Insurance Company identified the 10 safest and 10 least-safe U.S. cities.

It is noted that mean is used to measure the safety of a city. It is known that outliers have more effect on the mean value. The outlier drags the center or mean value toward it. Also, small samples usually have more variation. This could be the reason why small cities are on both safe and least safe cities lists.

So, the correct option is d.

Options (a) and (c) do not include any interpretation in terms of mean. Option (b) suggests that data is bimodal, but it does not signify why small cities are more in the lists. Option (e) does not conclude in terms of mean. Option (f) suggests the phenomenon of traffic congestion in big cities, but it cannot be considered only because of traffic the mean year is less. Option (g) does not imply statistically meaningful evidence to suggest the claim. And, option (h) is almost the same as option (d). However, since it does not suggest more about the variation, it is incorrect. Thus, except option (d), the remaining all statements are not recommended.

Therefore, option D is the correct answer

"Your question is incomplete, probably the complete question/missing part is:"

From among the 300 largest cities in the United States, FleeceU Insurance Company identified the 10 safest and 10 least-safe U.S. cities based on the mean number of years drivers went between automobile accidents. The cities on both lists were the smaller cities on the list of the 300 largest. Use facts about the sampling distribution model of the sample mean to select the choice below that explains why this is not surprising.

a. More people in larger cities drive older cars that are more accident prone.

b. In smaller cities, the distribution of the mean number of years drivers go between accidents is bimodal, which makes it more likely they will be in the safest and least-safe cities.

c. Larger cities have a higher incidence of hit-and-run accidents.

d.Cities in which the mean is based on a smaller number of drivers will have greater variation in their means and are therefore more likely to be both safest and least safe.

e. Accident statistics are more accurate in smaller cities.

f. Traffic congestion in larger cities decreases the mean number of years drivers go between accidents but not enough to place larger cities In the least-safe group.

g.Large cities are not on the safest list because their mean time between accidents is reduced by people who "stage" accidents for purposes of insurance fraud.

h.Smaller cities are safer, but a few accident-prone drivers (outliers) in some small cities decreases the mean number of years between accidents, resulting in these cities being listed on the least-safe list.

x = 8.8

Step-by-step explanation:

First, you have to solve the side length for the smaller triangle.

[tex]c= \sqrt{ a^{2} +b^{2} }\\c= \sqrt{5^{2}+4^{2} } \\\\c=\sqrt{25+16} \\c=\sqrt{41} \\c= 6.4\\[/tex]

Now for the bigger square.

[tex]c= \sqrt{ a^{2} +b^{2} \\} \\c = \sqrt{6.4^{2} +6^{2} } \\c= \sqrt{40.96+36} \\c= \sqrt{ 76.96}\\c= 8.77\\[/tex]

Rounded to the nearest tenth = 8.8

Answer:

m angle BCA =48 degrees

m angle ABC =70 degrees

m angle BAC=62 degrees

m angle BCD=132 degrees

Step-by-step explanation:

First you know that both interior angles have to equal the exterior angles (sorry I forgot what the name of the property). This means that the equation will be 6x-8+4x+10=12x-24. Simplify this to get 10x-2=12x-24. Simplify again to get 2x=26. Divide each side by 2 to get x=13. Now that you know x is equal to 13, you should plug x into angle ABC, BAC, and BCD. When you finish, angle ABC should be 70 degrees, angle BAC should be 62, and BCD should be 132.  To find angle BCA, you know that angle ABC is 70 degrees and BAC is 62 degrees. Every triangle has to equal 180 degrees so the equation should be 180-70-62 which is equal to 48. Therefore, m angle BCA =48 degrees, m angle ABC =70 degrees, m angle BAC=62 degrees, and m angle BCD=132 degrees. With this you can mark the correct choices.
