Step-by-step explanation:

The range of the boys is 60-120

while the range of the girls is 70-150

The medium of the boys is 90,

the medium of the girls is 110 (as it is between 100 and 120 so the medium is 110)

Answer:

A. $3,992.50

Step-by-step explanation:

Pavi has a credit limit of $8,000.

The credit statement says that the current balance is $4,007.50.

The margin Pavi has is the limit ($8,000) minus the current balance ($4.007.50), so 8000 - 4007.50 = 3992.50

It could have been guessed easily, because the balance is roughly half of the credit limit... so what's left is roughly half of the credit limit.   And the first answer is the only one close to that half-limit number ($4,000).

Answer:

Second option: [tex]f(x) =-7x^2 -x + 2 [/tex]

Step-by-step explanation:

A quadratic function has the form:

[tex]f(x)=ax^2+bx+c[/tex]

(Where [tex]a\neq0[/tex])

You can observe that the highest exponent of a quadratic function is 2.

Then, let's check which of the options shows a quadratic function:

1) [tex]f(x) = 2x^3 + 2x^2 - 4[/tex]

Its highest exponent is 3, then this is not a quadratic function.

2) [tex]f(x) =-7x^2 -x + 2 [/tex]

Its highest exponent is 2 and [tex]a\neq0[/tex], then this is a quadratic function.

3) [tex]f(x) = -3x + 2[/tex]

Its highest exponent is 1, then this is not a quadratic function.

4) [tex]f(x) =0x^2+3x-3[/tex]

You can observe that [tex]a=0[/tex], then this is not a quadratic function.

Answer:

1)LSA=219.91 m^2

 TSA= 298.45 m^2

2)LSA=785.39 ft^2

  TSA= 1099.55 ft^2

3)LSA=527.78 in^2

TSA=728.84 in^2

4)LSA=480.66 mm^2

TSA= 735.13 mm^2

5)LSA= 56 cm^2

  TSA= 72 cm^2

6)LSA=261 in^2

  TSA=391.5 in^2

Step-by-step explanation:

lateral surface area(LSA) of cone is calculated by: πrl

Total surface area(TSA) of cone is calculated by: πrl + πr^2

where r is radius of cone

           l is slant height of cone

Q1)

r=5m and l=14m

Putting value in formula:

LSA= πx 5x 14

      = 219.91

TSA= πx 5x 14 + π(5)^2

     = 298.45

Q2)

r=10ft and l=25ft

Putting value in formula:

LSA= πx 10x 25

      = 785.39

TSA= πx 10x 25 + π(10)^2

       = 1099.55

Q3)

r=8in and l=21in

Putting value in formula:

LSA= πx 8x 21

      = 527.78 in

TSA= πx 8x 21 + π(8)^2

     = 728.84

Q4)

r=9mm and l=17mm

Putting value in formula:

LSA= πx 9x 17

      = 480.66 mm

TSA= πx 9x 17 + π(9)^2

      = 735.13

Q5)

LSA of Pyramid is given by= 1/2(p)(l)

TSA of Pyramid is given by= 1/2(p)(l) +B

where p is perimeter of base

           B is area of base

and      l is slant height

Finding p= 4.length of each side       (as it is square base)

               =4x4

               = 16

finding B= s^2

             = 4^2

             =16

Putting values in formula:

LSA= 1/2(7)(16)

      = 56

TSA=1/2(7)(16) + 16

      = 72

Q6)

Finding p= 5.length of each side        (as it is Pentagon)

               =4x8.7

               = 34.8

finding B= 5[1/2(b)(h)]

             = 5[1/2(8.7)(6)]

             =130.5

Putting values in formula:

LSA= 1/2(34.8)(15)

      = 261

TSA=1/2(34.8)(15) + 130.5

      = 391.5 !

Answer: w = 61

Step-by-step explanation:

If the wall is 456 cm then the carpenter has already used up 334 cm of the wall on the other book cases. So 456-334 = 122 and since both of the bookcases are going to be the same width you divide 122 by 2 which gives you 61. Hope this helps :).

[tex]\frac{4}{4}total[/tex]

[tex]\frac{4}{4} - (\frac{2}{4} + \frac{1}{4} )[/tex]

[tex]\frac{4}{4} - \frac{3}{4} = \frac{1}{4}[/tex]

[tex]\frac{1}{4}[/tex] of the candy bar is remaining

1/4 of the candy bar is left.

First, let's add up the fractions of the candy bar that Jim and his brother ate:

Jim ate = 1/4

his brother ate = 2/4.

To find out how much they ate in total, we add these fractions:

1/4 + 2/4

= 3/4

So, they ate a total of 3/4 of the candy bar.

Now, to find out how much of the candy bar is left, we subtract the total amount they ate from 1 (the whole candy bar):

1 - 3/4

= 1/4

So, 1/4 of the candy bar is left.

PQ^2=(X2-X1)+(Y2-Y1)^2

PQ^2=(4+3)^2+(25-1)^2

PQ^2=625

PQ=25 unit

The length of the segment PQ is 25 units.

Given: Segment PQ

P = (x₁, y₁) = (-3, 1) and Q = (x₂, y₂) = (4, 25)

We have to find the length of the segment PQ.

Length of the segment PQ can be found by using the distance formula.

⇒ PQ = [tex]\sqrt{(x_2 -x_1)^2+(y_2-y_1)^2}[/tex]

⇒ PQ = [tex]\sqrt{[4-(-3)]^2+(25-1)^2}[/tex]

⇒ PQ = [tex]\sqrt{7^2+24^2}[/tex]

⇒ PQ = [tex]\sqrt{49+576}[/tex]

⇒ PQ = [tex]\sqrt{625}[/tex]

⇒ PQ = 25 units

Therefore, the length of the segment PQ is 25 units.

The area of the shaded sector is

[tex]Area =\pi \: {in}^{2} [/tex]

EXPLANATION

The area of a sector is calculated using the formula,

[tex]Area = \frac{central \: angle}{360 \degree} \: \times \pi \: {r}^{2} [/tex]

Fro the diagram, the central angle is 90°

The radius of the circle is 2 in.

[tex]Area = \frac{90 \degree}{360 \degree} \: \times \pi \: {2}^{2} {in}^{2} [/tex]

[tex]Area = \frac{1}{4} \: \times \pi \: 4 {in}^{2} [/tex]

This finally simplifies to

[tex]Area =\pi \: {in}^{2} [/tex]

Answer:

Area of shaded region = 3.14  in²

Step-by-step explanation:

Formula:-

Area of circle = πr²

Where 'r' is the radius of circle

It is given a circle with radius 2 in.

To find the area of circle

Here r = 2 in

Area = πr²  = 3.14 * 2² = 12.56 in²

To find the area of shaded region

Here central angle of sector = 90°

area of sector= (90/360) * area of circle

 = (1/4)12.56 = 3.14  in²

The probability of selecting a boat from Rhode Island is 7 out of 14, which simplifies to 1/2, or 50%. There's an equal chance of picking a boat from Rhode Island as not.

The probability of selecting a boat from Rhode Island at the marina is calculated by dividing the number of Rhode Island boats by the total number of boats.

There are 7 boats from Rhode Island and 14 boats in total.

Therefore, the probability is 7 out of 14, which simplifies to 1/2 when reduced.

This can also be written as a decimal, 0.5, or a percentage, 50%, indicating that there is an equal chance of selecting a Rhode Island boat as there is of selecting a boat from another place.

Thus, there's an equal chance of picking a boat from Rhode Island as not.

Final answer:

The probability that a randomly selected boat will be from Rhode Island is 1/2.

Explanation:

To calculate the probability that a randomly selected boat at the marina is from Rhode Island, we use the basic probability formula:

Probability (P) of an event = (Number of favorable outcomes) / (Total number of possible outcomes)

Given that there are 7 boats from Rhode Island and a total of 14 boats at the marina, the probability (P) that a randomly selected boat is from Rhode Island is:

P(Rhode Island) = 7 / 14 = 1/2.

Therefore, the simplified fraction representing the probability is 1/2.

Step-by-step explanation:

The correct radius for Circle Y, given its circumference, is 3/π units. The provided equations do not reflect this value, and hence, are not correct.

The question essentially asks for the radius of Circle Y. The given information includes the radius of Circle X (rX = 6 units) and the circumferences of both circles (CX = 12π units and CY = 6 units).

Remember that the formula for the circumference of a circle is C = 2πr. Using this formula, we can find the radius of Circle Y by dividing its circumference by 2π. Hence,

rY = CY / (2π) = 6 / (2π) = 3/π units.

Consequently, the equation rY = rX is false, because 3/π is not equal to 6. Other given equations do not apply to this particular problem.

   Parabola defined by the equation y = -x² - 3x + 6 will be represented by the picture attached.

Equation of the parabola given in the question is,

y = -x² - 3x + 6

Convert this equation in the vertex form, [y = a(x - h)² + k, here (h, k) is the vertex of the parabola]

y = -x² - 2(1.5)x - (1.5)² + (1.5)² + 6

  = -(x + 1.5)²+ (1.5)² + 6

  = -(x + 1.5)² + 2.25 + 6

  = -(x + 1.5)² + 8.25

From this equation vertex of the parabola will be (-1.5, 8.25).

Leading coefficient 'a' = -1 (negative)

y - intercept of the equation → y = -(0 - 1.5)² + 8.25

                                                  y = 6

x- intercept of the equation → 0 = -(x - 1.5)² + 8.25

                                                 (x - 1.5) = √8.25

                                                 x = 1.372, -4.372

  Therefore, parabola will open downwards (a is negative), y-intercept (0, 6) and x-intercepts as (-4.372, 0), (1.372, 0) and vertex as (1.5, 8.25).
