Answer:
C is a right triangle
Step-by-step explanation:
To determine if the triangle is right use Pythagoras' identity
A
9.4² = 88.36
6.4² + 7.1² = 91.37
88.36 ≠ 91.37 , thus not a right triangle
B
8.4² = 70.56
5.2² + 6.3² = 66.73
70.56 ≠ 66.73 , thus not a right triangle
C
9.7² = 94.09
6.5² + 7.2² = 94.09
Thus C is a right triangle
D
8.4² = 70.56
5.1² + 7.3² = 79.3
70.56 ≠ 79.3 , thus not a right triangle
Answer:
Answer C is the correct one
Step-by-step explanation:
Remember that the Pythagorean Theorem applies only to right triangles. In Answer A, the legs of the triangle shown are 6.4 and 7.1; we apply the Pythagorean Theorem and check whether the length of the hypotenuse is indeed 9.4:
6.4² + 7.1² = 40.96 + 50.41 = 91.37.
Is √91.37 equal to 9.4? Not quite! For now, reject Answer A.
Answer B: 5.2² + 6.3² yields 66.73. Is this equal to 8.4²? No, it is not.
Reject Answer B.
Answer C: 7.2² + 6.5² = 94.09. Is this equal to 9.7²? YES. So Answer C is the correct one.

Identify the lateral area and surface area of a right cone with radius 6 cm and slant height 13 cm.
Answers
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.
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?
Answers
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.
Ruby has a points card for a movie theater.
• She receives 50 rewards points just for signing up.
She earns 14.5 points for each visit to the movie theater.
She needs 224 points for a free movie ticket.
.
How many visits must Ruby make to earn a free movie ticket?
Answers
To work this out you must do 224 (total of points needed) subtract 50 as she already got 50) Which equals 174
Then 174 divide by 14.5 (how much she gets for it to go) which equals 12 there for she need to go 12 times to get a free ticket

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.

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?
Answers
+8.5%2A11+=+93.5+ in2
There are 4 corners, so
+4%2A2+=+8+ in2 total removed
+93.5+-+8+=+85.5+
The new area is 85.5 in2
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,

What do the plots tell you about the test scores of Ms. Brodie's class?
Answers
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.
