Question Help Of 515515 samples of seafood purchased from various kinds of food stores in different regions of a country and genetically compared to standard gene fragments that can identify the species, 6262% were mislabeled. a) Construct a 9090% confidence interval for the proportion of all seafood sold in the country that is mislabeled or misidentified. b) Explain what your confidence interval says about seafood sold in the country. c) A government spokesperson claimed that the sample size was too small, relative to the billions of pieces of seafood sold each year, to generalize. Is this criticism valid?
Answer:
(0.5848 ; 0.6552)
We are confident that about 58% to 66% of sea foods in the country are Mislabelled.
No, criticism isnt valid and generalization can be made once the assumptions for constructing a confidence interval is met.
Step-by-step explanation:
Sample size, n = 51
p = 0.62
1 - p = 1 - 0.62 = 0.38
n = 515
Confidence level = 90% = Zcritical at 90% = 1.645
Confidence interval = (p ± margin of error)
Margin of Error = Zcritical * sqrt[(p(1-p))/n]
Margin of Error = 1.645 * sqrt[(0.62(0.38))/515]
Margin of Error = 1.645 * 0.0214
Margin of Error = 0.035203
Lower boundary = (0.62 - 0.035203) = 0.584797
Upper boundary = (0.62 + 0.035203) = 0.655203
(0.5848 ; 0.6552)
We are confident that about 58% to 66% of sea foods in the country are Mislabelled.
No, criticism isnt valid and generalization can be made once the assumptions for constructing a confidence interval is met.

Answer:
[tex]\boxed {\boxed {\sf D. \ x=20}}[/tex]
Step-by-step explanation:
If line m and line r are parallel, the two angles must be congruent, because they are alternate interior angles. Notice how the 2 lines and the transversal form a backwards "Z" and the angles are in the inner corners.
So, if the angles are congruent, we can set them equal to each other.
3x-357x-115[tex]7x-115=3x-35[/tex]
Now, solve for x by isolating the variable. First, move all the constants to one side and the terms with variables to another.
115 is being subtracted and the inverse of subtraction is addition. Add 115 to both sides.
[tex]7x-115+115=3x-35+115\\7x= 3x+(-35+115) \\7x=3x+80[/tex]
3x is being added and the inverse of addition is subtraction. Subtract 3x from both sides.
[tex]7x-3x=3x-3x+80 \\4x=80[/tex]
x is being multiplied by 4. The inverse of multiplication is division. Divide both sides by 4.
[tex]4x/4=80/4\\x=20[/tex]
If the lines are parallel, then x=20 so the angles are congruent.

Step-by-step explanation:
A sheet of paper has dimensions of 8.5 in x 11 in. If you cut 2 in2 from each corner of the sheet, what will the area of the sheet of paper be?
Area of the sheet when 2 in[tex] \sf ^2 [/tex] hasn't been cut from each corner of the sheet :-
→ Area = Length × Breadth
→ Area = ( 8.5 × 11 ) in[tex] \sf ^2 [/tex]
→ Area = 93.5 in[tex] \sf ^2 [/tex]
Area of the part cut from it :
2 in[tex] \sf ^2 [/tex] has been cut from each corner of the sheet. [ A sheet has 4 corners. ]→ ( 4 × 2 ) in[tex] \sf ^2 [/tex]
→ 8 in[tex] \sf ^2 [/tex]
Remaining area :
→ Remaining area = 93.5 in[tex] \sf ^2 [/tex] - 8 in[tex] \sf ^2 [/tex]
→ Remaining area = 85.5 in[tex] \sf ^2 [/tex]Therefore,
The area of the sheet of paper will be 85.5 in[tex] \sf ^2 [/tex]Solve for the value of k. how? how can I solve it
Answer:
6
Step-by-step explanation:
The total of all the angles must be 180, since there is a straight line. We already know the 40 degree angle and the 90 degree angle, meaning that the remaining angle must be equal to 180 - 90 - 40, which is 50 degrees. Therefore, 50 = 7k + 8. 7k = 50-8 = 42, and k = 6.

Can someone explain how to solve
———-
-2x+2y=2
-x-2y=1
————-
by elimination?
Answer:
when using elimination you "eliminate one variable by adding the equations", so basically in this equation 2y-2y cancel out when you add the equations together. so, you'll find x first. once you find the value of x, then you plug x into one of the equations to find the ordered pair solution, which happens to be (-1,0) in this solution.

Identify the lateral area and surface area of a right cone with radius 6 cm and slant height 13 cm.
Answer:
The lateral surface area is about = 269.747749 m squared
The surface area is about = 382.787749 m squared
Step-by-step explanation:
Answer:
L = 245 cm2 ; S = 358.1 cm2
Step-by-step explanation:
The lateral area of a right cone with radius r and slant height l is L=πrl.
The figure shows a right cone.
Apply the formula for the lateral area of a right cone L=πrl.
Substitute the known values for the radius r=6 cm and the slant height l=13 cm.
L=π(6)(13)=78π
Use a calculator to approximate. Round your answer to the nearest whole number.
L≈245
The lateral area of the cone is 245 cm2.
The surface area of a right cone with lateral area L and base area B is S=L+B, or S=πrl+πr2.
Substitute the given value for the radius r=6 cm into the formula for the area of a circle, B=πr2.
B=π(6)2=36π
Therefore, the base area is 36π cm2.
To calculate the surface area of the cone, substitute the known values into formula for surface area.
S=78π+36π=114π
Use a calculator to approximate. Round your answer to the nearest tenth.
S≈358.1
Therefore, the surface area of the cone is about 358.1 cm2.

At Wegmans a 12 pack of paper towels costs $15.72. At Tops a 10 pack of paper towels cost $13.35. Which store has the better buy? What is the difference in unit prices?
Answer:
Wegman's, roughly 3 cents
Step-by-step explanation:
Divide the price by the number of paper towels in the pack to get the unit price.
$15.72/12= $1.31
$13.35/10= $1.335, round since it's money, $1.34
$1.34-$1.31= $0.03 or 3 cents
Wegmans has the better buy, as their unit price is lower.
The difference in unit prices between the two stores is $0.03 per paper towel.
To determine which store has the better buy, we need to compare the unit prices of paper towels at both Wegmans and Tops.
The unit price is the cost per paper towel.
For Wegmans:
Cost of 12 pack of paper towels = $15.72
Number of paper towels in the pack = 12
Unit price at Wegmans = Total cost / Number of paper towels
Unit price at Wegmans = $15.72 / 12 = $1.31 per paper towel
For Tops:
Cost of 10 pack of paper towels = $13.35
Number of paper towels in the pack = 10
Unit price at Tops = Total cost / Number of paper towels
Unit price at Tops = $13.35 / 10 = $1.34 per paper towel
Now, we compare the unit prices:
At Wegmans, the unit price is $1.31 per paper towel.
At Tops, the unit price is $1.34 per paper towel.
The store with the lower unit price has the better buy.
In this case, Wegmans has the better buy, as their unit price is lower.
To find the difference in unit prices:
Difference in unit prices = Unit price at Tops - Unit price at Wegmans
Difference in unit prices = $1.34 - $1.31 = $0.03 per paper towel
So, the difference in unit prices between the two stores is $0.03 per paper towel.

Step-by-step explanation:
Ms. Brodie drew these box-and-whisker plots to represent her students' scores on the mid-year test and the final exam.
What do the plots tell you about the test scores of Ms. Brodie's class?
Answer:
The scores of the final exam are, in general, lower than the scores in the mid-term exam.
Step-by-step explanation:
First a little description of these graphs.
The first interval (only a line) represents the bottom 25% of the sample.
The second interval (the left part of the rectangle) represents the lower quartile, which is another 25% of the sample.
The third interval, the right part of the rectangle, represents the upper quartile, which is another 25% of the sample.
And the final segment represents the top 25%.
Looking at the first graph, we can see that the worst scores (for the bottom 25%) are between 44 and 63.
While in the second graph, the wors scores are between 44 and 59, this means that we have more people with bad scores in the final exam.
Now if we look at the lower quartile in the first graph, we can see that the range of scores is between 63 and 74.
While in the second graph the range is between 59 and 71.
Again, we can see that in the final exam the scores dropped a bit in this quartile.
In the upper quartile, we have a similar case.
In the first graph, the scores go between 74 and 81, while in the second graph the scores go between 71 and 79.
And in the final segment, we also can see a drop in the scores, because in the first graph the range is from 81 to 93
while in the second graph the range is from 79 and 92.
So in all the "segments", we can see that the scores dropped. And this is the only conclusion we can make from the graphs, the scores of the final exam are, in general, lower than the scores in the mid-term exam.

Answer:
c = 88
Step-by-step explanation:
c = 180 - a - b
c = 180 - 43 - 49
c = 137 - 49
c = 88
Answer:
c= 88
Step-by-step explanation:
What you want to do is take (a) which it says is 43 and (b) which it says is 49 and plug them into the equation. Here it says c = 180 - a - b so what you would do is take c=180-43-49 or c=88.
Hopefully that helps ;)
