Responder:

y = -6X + 36

Explicación paso a paso:

Dados los datos:

CANTIDADES __PRECIO

5 ___ 6

4 ___ 12

3 ___ 18

2 ___24

1 ___ 30

Usando una calculadora de modelo lineal:

La ecuación del modelo lineal obtenida con una calculadora de regresión es:

y = -6X + 36

Donde y = precio; - 6 = pendiente; Intercepción = 36

Se pudo observar que como reducción en la cantidad demandada puede ser como resultado de un aumento en el precio.

peter picked 35 buckets of strawberries the average number of strawberries in each of these buckets were 97 from the buckets the
Alekssandra [29.7K]
Multiply 35 by 97 to figure out how many strawberries there were: 35•97=3,395. Divide by 14 to figure out how many punnets: 3395/14=242.5. Multiply by 1.95 to figure out how much the strawberries went for: 242.5•1.95=472.875. Round to the nearest cent: 472.875=472.88. The answer: $472.88 :)

The school that Jennifer goes to is selling tickets to a play. On the first day of ticket sales the
sweet [91]

Answer:

Adult ticket = $11

Children ticket = $9

Step-by-step explanation:

Let the price of adult tickets be x and let the price of children's ticket be y

For the first day, the equation of sales can be put as

3x + 12y = 141..........1

For the second day, the equation of sales can be put as:

13x + 6y = 197............2

We then take these two equations together and solve simultaneously.

3x + 12y = 141.......1

13x + 6y = 197........2

Solving by elimination method, we Multiply through equation 1 by 13 and multiply through equation 2 by 3.

39x + 156y = 1833.........3

39x + 18y = 591..............4

Then subtract equation 4 from equation 3

138y =1242

y = 9

Substitute "y=9" into equation 1 to find x

3x + 12(9) =141

3x + 108 = 141

3x = 141 - 108

3x = 33

x = 11

Hence,

Price of adult ticket = $11

Price of children ticket = $9

The circumference of the ellipse approximate. Which equation is the result of solving the formula of the circumference for b?
Serhud [2]

Answer:

b = \sqrt{\frac{C^{2} }{2(\pi )^{2} }  -  a^{2}}

Step-by-step explanation:

Given - The circumference of the ellipse approximated by C = 2\pi \sqrt{\frac{a^{2} + b^{2} }{2} }where 2a and 2b are the lengths of 2 the axes of the ellipse.

To find - Which equation is the result of solving the formula of the circumference for b ?

Solution -

C = 2\pi \sqrt{\frac{a^{2} + b^{2} }{2} }\\\frac{C}{2\pi }  =  \sqrt{\frac{a^{2} + b^{2} }{2} }

Squaring Both sides, we get

[\frac{C}{2\pi }]^{2}   =  [\sqrt{\frac{a^{2} + b^{2} }{2} }]^{2} \\\frac{C^{2} }{(2\pi)^{2}  }   =  {\frac{a^{2} + b^{2} }{2} }\\2\frac{C^{2} }{4(\pi)^{2}  }   =  {{a^{2} + b^{2} }

\frac{C^{2} }{2(\pi )^{2} }  = a^{2} + b^{2} \\\frac{C^{2} }{2(\pi )^{2} }  -  a^{2} = b^{2} \\\sqrt{\frac{C^{2} }{2(\pi )^{2} }  -  a^{2}}  = b

∴ we get

b = \sqrt{\frac{C^{2} }{2(\pi )^{2} }  -  a^{2}}
