The tallest living man at one time had a height of 265 cm. The shortest living man at that time had a height of 109.1 cm. Heights of men at that time had a mean of 173.73 cm and a standard deviation of 8.65 cm. Which of these two men had the height that was more​ extreme?

Answer:

31

Step-by-step explanation:

For rectangle ABCD, AC and BD are the lengths of the diagonals. The diagonals of a rectangle are congruent.

AC = BD

3x + 7 = 131 - x

Add x to both sides.

4x + 7 = 131

Subtract 7 from both sides.

4x = 124

Divide both sides by 4.

x = 31

5 feet 6 inches is equal to ((5*12)+6) inches, which is equal to 66 inches since 5*12=60 and 60+6=66

2 feet 9 inches is equal to ((2*12)+9) inches, which is equal to 33 inches since 2*12=24 and 24+9=33

Since 66 and 33 are the length and width (there isn't any specific order as to which measurement is the length or width) and the question is asking for square inches,(which is the area) so what needs to be done next is 66*33, which equals 2178, the square inches of plastic needed is 2718 square inches.

I couldn't keep the answer in the format of _ft _in because they are asking for the area in inches, and I don't think it would be smart to convert inches to decimal values of feet for reasons I won't talk about.

So yeah, your answer is 2178 square inches of plastic.

The distance between the lions and the monkeys is 88 feet

To determine the distance between the lions and the monkeys, we make use of the following equivalent ratio

x : 132 = 80 : 120

Express as fraction

[tex]\frac{x}{132} = \frac{80}{120}[/tex]

Solve for x

[tex]x = \frac{80}{120} * 132[/tex]

Multiply

[tex]x = 88[/tex]

Hence, the distance between the lions and the monkeys is 88 feet

Step-by-step explanation:

for the each year, the interest is increased by 2%,

so after 1 year, earned interest is 2% of $400

=2/100 × 400=$8

so the earned balance is $(400+8)=$408

so after 2 year, earned interest is 2% of $408

=2/100 × 408=$8.16

so the earned balance is $(408+8.16)=$416.16

after 3 year, earned interest is 2% of $416.16

=2/100 × 416.16=$8.32

so the earned balance is $(416.16+8.32)=$424.48

after 4 year, earned interest is 2% of $424.48

=2/100 × 424.48=$8.48

so the earned balance is $(424.48+8.48)=$480.48

after 5 year, earned interest is 2% of $480.48

=2/100 × 480.48=$9.6

so the earned balance is $(480.48+9.6)=$490.08

after 6 year, earned interest is 2% of $490.08

=2/100 × 490.08=$9.8

so the earned balance is $(490.08+9.8)=$499.88

therefore the interest earned after 6 years is

$(8+8.16+8.32+8.48+9.6+9.8)=$52.36

and the balance after 6 years is $499.88

Answer:

Total number of plants = 3t - 15 = 3(t-5) tomato plants

Explanation:

We are given that:

Erin planted t tomato plants

Leo planted 5 fewer tomato plants than Erin, this means that:

Leo planted = t - 5 tomato plants

Fillip planted 10 fewer tomato plants than Erin, this means that:

Fillip planted = t - 10 tomato plants

Now, we want to find the total number of tomato plants

This means that we will add the number of plants planted by Erin, Leo and Fillip

Therefore:

Total number of plants = t + t - 5 + t - 10

Total number of plants = 3t - 15 = 3(t-5) tomato plants

Hope this helps :)

Final answer:

The expression that represents the total number of tomato plants Erin, Leo, and Filipe planted is 3t - 15, where t is the number of plants Erin planted.

Explanation:

If Erin planted t tomato plants, then we can express the number of tomato plants Leo and Filipe planted using algebraic expressions that are based on this initial quantity. Leo planted 5 fewer tomato plants than Erin, so we can describe the number of plants Leo planted as t - 5. Similarly, Filipe planted 10 fewer tomato plants than Erin, and his number can be represented by t - 10.

To find the total number of tomato plants all three of them planted together, you would add these expressions:

Total number of plants = Erin's plants + Leo's plants + Filipe's plants

Total = t + (t - 5) + (t - 10)

Simplify the expression by combining like terms:

Total = t + t - 5 + t - 10

Total = 3t - 15

So the expression that represents the total number of tomato plants Erin, Leo, and Filipe planted in all is 3t - 15.

Answer:

Using Thales theorem, we have:

AP/BP = AQ/CQ

=> 8/40 = x/45

=> x = (45 · 8)/40 = 9

24.

Also using Thales theorem, we have:

5/6 = (x - 1)/12

x - 1 = (12 · 5)/6 = 60/6 = 10

x     = 10 + 1 = 11

25.

Because we already have the bisector, we know that:

x/6.9 = 18.3/6.2

x        = (6.9 · 18.3)/6.2 ≈ 20.4

Answer:

D. Events E and B are independent.

Step-by-step explanation:

It can be determined that Events E and B are independent. The correct answer is: D.

To determine independence between events, we can use the formula:

[tex]\[ P(A \cap B) = P(A) \times P(B) \][/tex]

Let's check for events D and A:

[tex]\[ P(D \cap A) = 0.2 \][/tex]

[tex]\[ P(D) \times P(A) = 0.5 \times 0.2 = 0.1 \][/tex]

Since [tex]\(0.2 \neq 0.1\),[/tex] events D and A are not independent.

Checking for events D and B:

[tex]\[ P(D \cap B) = 0.3 \][/tex]

[tex]\[ P(D) \times P(B) = 0.5 \times 0.3 = 0.15 \][/tex]

Since [tex]\(0.3 = 0.15\)[/tex], events D and B are independent.

Similarly, events A and B:

[tex]\[ P(A \cap B) = 0.15 \][/tex]

[tex]\[ P(A) \times P(B) = 0.2 \times 0.5 = 0.1 \][/tex]

Since [tex]\(0.15 \neq 0.1\)[/tex],events A and B are not independent.

For events E and B:

[tex]\[ P(E \cap B) = 0.15 \][/tex]

[tex]\[ P(E) \times P(B) = 0.3 \times 0.5 = 0.15 \][/tex]

Since [tex]\(0.15 = 0.15\)[/tex], events E and B are independent.

Therefore, the correct answer is: D. Events E and B are independent.

To know which of the products results in a difference of square, we need to remember the difference of squares from:

The difference of squares form is:

[tex](a+b)(a-b)=a^{2}-b^{2}[/tex]

So, discarding each of the given options in order to find which products result in a difference of squares, we have:

[tex](x-y)(y-x)=xy-x^{2}-y^{2} +yx=-x^{2} -y^{2}[/tex]

So, the obtained expression is not a difference of squares.

[tex](6-y)(6-y)=36-6y-6y+y^{2}=y^{2}-12y+36[/tex]

So, the obtained expression is not a difference of squares.

[tex](3+xz)(-3+xz) =(xz+3)(xz-3)=(xz)^{2}-3xz+3xz-(3)^{2}\\\\(xz)^{2}-3xz+3xz-(3)^{2}=(xz)^{2}-(3)^{2}[/tex]

So, the obtained expression is a difference of squares since it matches with the form of the difference of squares.

[tex](y^2-xy)(y^2+xy)=(y^{2})^{2}+y^{2}*xy-y^{2}*xy-(xy)^{2} \\\\(y^{2})^{2}+y^{2}*xy-y^{2}*xy-(xy)^{2}=(y^{2})^{2}-(xy)^{2}[/tex]

So, the obtained expression is a difference of squares since it matches with the form of the difference of squares.

[tex](25x-7y)(-7y+25x)=-175xy+(25x)^{2}+49y^{2}-175xy\\\\-175xy+(25x)^{2}+49y^{2}-175xy=(25x)^{2}+49y^{2}-350xy[/tex]

So, the obtained expression is not a difference of squares

[tex](64y^2+x^2)(-x^2+64y^2)=(64y^2+x^2)(64y^2-x^2)\\\\(64y^2+x^2)(64y^2-x^2)=(64y^{2})^{2} -(x^{2}*64y^{2})+(x^{2}*64y^{2})-(x^{2})^{2}\\ \\(64y^{2})^{2} -(x^{2}*64y^{2})+(x^{2}*64y^{2})-(x^{2})^{2}=(64y^{2})^{2}-(x^{2})^{2}[/tex]

So, the obtained expression is a difference of squares since it matches with the form of the difference of squares.

Hence, the products that result in a difference of squares are:

C) [tex](3+xz)(-3+xz)[/tex]

D) [tex](y^2-xy)(y^2+xy)[/tex]

F) [tex](64y^2+x^2)(-x^2+64y^2)[/tex]

Step-by-step explanation:

To calculate the conditional probability, we need to find the probability of transferring two red balls and two blue balls from Bowl I to Bowl II and the probability of selecting a blue ball from Bowl II which is 0.0923

To calculate the conditional probability, we need to find the probability of transferring two red balls and two blue balls from Bowl I to Bowl II and the probability of selecting a blue ball from Bowl II.

First, we calculate the probability of transferring two red balls and two blue balls from Bowl I to Bowl II. There are 14 balls in Bowl I, so the probability of transferring a red ball on the first draw is 8/14. After transferring one red ball, there are now 13 balls in Bowl I, so the probability of transferring another red ball is 7/13. Similarly, the probability of transferring a blue ball on the first draw is 6/14, and the probability of transferring another blue ball is 5/13. To find the overall probability, we multiply these probabilities: (8/14) * (7/13) * (6/14) * (5/13).

Next, we calculate the probability of selecting a blue ball from Bowl II. After transferring four balls from Bowl I, there are now 10 balls in Bowl II, with 6 blue balls. The probability of selecting a blue ball is therefore 6/10.

Finally, we calculate the conditional probability by dividing the probability of transferring two red balls and two blue balls from Bowl I to Bowl II by the probability of selecting a blue ball from Bowl II:

= (8/14) * (7/13) * (6/14) * (5/13) / (6/10)

= 0.0923 (rounded to four decimal places).

Area = base * height

Area = 15 * 8 = 120 square centimeters

Answer:

  10.24 square feet

Step-by-step explanation:

The area of one triangular face is ...

  A = (1/2)bh = (1/2)(0.8 ft)(6 ft) = 2.4 ft²

Then the four triangular faces will have a total area of ...

  lateral area = 4·(2.4 ft²) = 9.6 ft² . . . . . sufficient to help you choose the correct answer

__

The area of the square base is the square of the side length:

  base area = (0.8 ft)² = 0.64 ft²

Then the total surface area is ...

  surface area = lateral area + base area

  surface area = 9.6 ft² + 0.64 ft² = 10.24 ft²

You would multiply the Area of a square which is B x H the Area for the square is 0.8 x 0.8 = 0.64

Then you multiply the Area of a triangle and the Area of a triangle is B x H divided by 2  and so you multiply the number of triangles there are which is 0.8 x 6 = 4.8 then divide that by 2 which is 2.4 then multiply that with the number of triangles we have all together. there are 4 triangles.

Multiply 2.4 x 4 = 9.6 then add the Area of the square which is 0.64 + 9.6 and the answer is 10.24

Answer:

1.69 ft (approx.)

Step-by-step explanation:

Formula for Volume of cylinder: pi x radius squared x height

Plug in 108 for volume, 3.14 for pi and 12 for height:

108 = 3.14 x r squared x 12

Multiply 3.14 and 12

108 = 37.68 x r squared

Divide both sides by 37.68

2.87 = r squared

"Unsquare" both sides (square root)

1.69 ft. = radius (approximate answer, rounded to nearest hundredth)

Answer:

1.69 ft

Step-by-step explanation:

V = πr²h formula  of a cylinder.

Volume = 108 ft

Height = 12 ft

Radius = r

V = πr²h

108 ft = 22/7 × r² × 12 ft

π = 22/7 or 3.14

108 ft = 264/7r²

108 ft  = 37.71r²

divide both sides by 37.71

108 ft/37.71 =r²

2.86 ft = r²

square root both side

√2.86 ft = √r²

the square cancels the square root

1.69 ft.

                                 To check

V = πr²h

108 = 22/7 × (1.69)² 12

108 = 22/7 × 2.8561 × 12

108 = 107.61≈108

108 ft = 108 ft.

Answer:

(x - 3)² + (y - 2)² = 17

Step-by-step explanation:

The equation of a circle in standard form is

(x - h)² + (y - k)² = r²

where (h, k) are the coordinates of the centre and r the radius

here (h, k) = A(3,2), thus

(x - 3)² + (y - 2)² = r²

The radius is the distance from the centre to a point on the circle

Calculate r using the distance formula

r = √ (x₂ - x₁ )² + (y₂ - y₁ )²

with (x₁, y₁ ) = (3, 2) and (x₂, y₂ ) = (- 1, 1) ← point on circle

r = [tex]\sqrt{(-1-3)^2+(1-2)^2}[/tex] = [tex]\sqrt{(-4)^2+(-1)^2}[/tex] = [tex]\sqrt{17}[/tex]

Hence r² = ([tex]\sqrt{17}[/tex] )² = 17

(x - 3)² + (y - 2)² = 17 ← equation of circle

Hello there!

Answer:

The slope is 9, and the y-intercept is –2

Step-by-step explanation:

The equation is y = 9x - 2

This follows the equation y = mx + b

Where as:

m = slope

b = y-intercept

When you know this, you would figure out that 9 is in the same place as m, and -2 is in the same place as b.

The y-intercept would not be a positive 2 because when there's a minus sign next to the number in the y-intercept spot, then you would have to bring that over to the number. We can also say the minus sign belongs to the 2, making it a -2.

With the information we know now, we can say that the slope of the equation is 9, and the y-intercept would be -2.

Therefore, giving your answer as "The slope is 9, and the y-intercept is –2"

Final answer:

The slope of the linear function represented by y=9x-2 is 9, and the y-intercept is -2. This is determined by comparing the equation to the slope-intercept form y = mx + b.

Explanation:

The slope and y-intercept of the linear function represented by the equation y=9x-2 can be identified by comparing it to the slope-intercept form of a linear equation, which is y = mx + b, where m is the slope and b is the y-intercept. In the given equation, 9 is the coefficient of x, which means it is the slope of the line. The constant term, -2, is the y-intercept because it indicates the point at which the line crosses the y-axis.
