Find the range & interquartile range of the data set represented by this box plot.

Answers

Answer:

60 and 25

Step-by-step explanation:

The range is the difference between the maximum value and the minimum value.

maximum value = 125, minimum value = 65

range = 125 - 65 = 60

------------------------------------------

The interquartile range is the difference between the upper quartile Q₃ and the lower quartile Q₁

Q₃ is the value at the right side of the box = 115

Q₁ is the value at the left side of the box = 90

interquartile range = 115 - 90 = 25

Vertex is:

x = -8/-2 = 4, y = 4² - 8*4 - 20 = -36

Correct choice is A

Find the MEAN of the temperatures. Round to the nearest tenths place.

A. 82.3

B. 89

C. 83

D. 78

Answers

Answer:

Mean of temperatures = 82.3 (Approx.)

Step-by-step explanation:

Given:

Number of days = 7 days

Temperatures in 7 days = 81, 78, 83, 89, 80, 87, 78

Find;

Mean of temperatures

Computation:

Mean = Sum of all observation / Number of observation

Mean of temperatures = Sum of all seven days temperature / Number of days

Mean of temperatures = [81 + 78 + 83 + 89 + 80 + 87 + 78] / 7

Mean of temperatures = 576 / 7

Mean of temperatures = 82.2857

Mean of temperatures = 82.3 (Approx.)

Answer:

x = 2 and -4

Step-by-step explanation:

(x + 1)² = 9

First, take the square root of both sides. This will eliminate the square on the left side.

(x + 1) = √9

Note that √9 can be 3 or -3.

Let's write out both possibilities.

(x + 1) = 3

(x + 1) = -3

Solve.

(x + 1) = 3

[subtract 1 from both sides]

x = 2

--

(x + 1) = -3

[subtract 1 from both sides]

x = -4

Your answers are 2 and -4.

Let's check our answers by plugging in the values back into the original equation.

(x + 1)² = 9

(2 + 1)² = 9

(3)² = 9

9 = 9

That solution is correct.

(x + 1)² = 9

(-4 + 1)² = 9

(-3)² = 9

9 = 9

That solution is also correct.

Your answer is correct.

Hope this helps!

The diameter of a circle is 14 ft.
What is the area of the circle in terms of π?

Answers

Answer:

49π ft²

Step-by-step explanation:

[tex]A=\pi r^2[/tex] where r is the radius of the circle

To find the radius, divide the diameter by 2:

14 ft ÷ 2 = 7 ft

Plug the radius 7 ft into the equation

[tex]A=\pi (7)^2\\A=49\pi[/tex]

Therefore, the area of the circle in terms of pi is 49π ft².

Which three lengths could be the lengths
of the sides of a triangle?
A. 4 cm, 8 cm, 13 cm

B. 13 cm, 11 cm, 23 cm

C. 5 cm, 18 cm, 12 cm

D. 25 cm, 8 cm, 16 cm

Answers

Given:

The three lengths in the options.

To find:

Which three lengths could be the lengths of the sides of a triangle?

Solution:

If the sum of two smaller sides is greater than the largest side, then the three sides can form a triangle otherwise the triangle is not possible.

In option A, the three sides are 4 cm, 8 cm, 13 cm. Here, the largest side is 13 cm.

Sum of two smaller sides is:

[tex]4+8=12[/tex]

[tex]4+8<13[/tex]

So, the triangle is not possible.

In option B, the three sides are 13 cm, 11 cm, 23 cm. Here, the largest side is 23 cm.

Sum of two smaller sides is:

[tex]13+11=24[/tex]

[tex]13+11>23[/tex]

So, the triangle is possible.

In option C, the three sides are 5 cm, 18 cm, 12 cm. Here, the largest side is 18 cm.

Sum of two smaller sides is:

[tex]5+12=17[/tex]

[tex]5+12<18[/tex]

So, the triangle is not possible.

In option D, the three sides are 25 cm, 8 cm, 16 cm. Here, the largest side is 25 cm.

Sum of two smaller sides is:

[tex]8+16=24[/tex]

[tex]8+16<25[/tex]

So, the triangle is not possible.

Therefore, the correct option is B. The three lengths 13 cm, 11 cm, 23 cm could be the lengths of the sides of a triangle.

Excerpt, Theodore Roosevelt, Inaugural AddressSaturday, March 4, 1905My fellow-citizens, no people on earth have more cause to be thankful than ours, and this is said reverently, in no spirit of boastfulness in our own strength, but with gratitude to the Giver ofGood who has blessed us with the conditions which have enabled us to achieve so large a measure of well-being and of happiness. To us as a people it has been granted to lay the foundations ofour national life in a new continent. We are the heirs of the ages, and yet we have had to pay few of the penalties which in old countries are exacted by the dead hand of a bygone civilization. Wehave not been obliged to fight for our existence against any allen race; and yet our life has called for the vigor and effort without which the manller and hardier virtues wither away. Under suchconditions it would be our own fault if we failed; and the success which we have had in the past, the success which we confidently believe the future will bring, should cause in us no feeling of[vanity), but rather a deep and abiding realization of all which life has offered us; a full acknowledgment of the responsibility which is ours; and a fixed determination to show that under a freegovernment a mighty people can thrive best, alike as regards the things of the body and the things of the soul.Much has been given us, and much will rightfully be expected from us. We have duties to others and duties to ourselves, and we can shirk nether. We have become a great nation, forced by thefact of its greatness into relations with the other nations of the earth, and we must behave as beseems a people with such responsibilities. Toward all other nations, large and small, our attitudemust be one of cordial and sincere friendship. We must show not only in our words, but in our deeds, that we are earnestly desirous of securing their good will by acting toward them in a spirit ofjust and generous recognition of all their rights. But justice and generosity in a nation, as in an individual, count most when shown not by the weak but by the strong. While ever careful to refrainfrom wrongdoing others, we must be no less insistent that we are not wronged ourselves. We wish peace, but we wish the peace of justice, the peace of righteousness. We wish it because wethink it is right and not because we are afraid. No weak nation that acts manfully and justly should ever have cause to fear us, and no strong power should ever be able to single us out as asubject for insolent aggression.What does the author mean with the phrase "we are the helrs of the ages ..."?
