Answer:

Constant of variation: 1/4

Slope of the line: 1/4

Step-by-step explanation:

The constant of variation means the relationship between variables does not change. When we want to identify the constant of variation for an equation, it is helpful to refer to one of the following formulas: xy = k (inverse variation) or y/x = k (direct variation), where k is the constant of variation.

The slope formula states that m = (y2 -- y1) / (x2 -- x1). The slope formula can be read as "slope equals the second y coordinate minus the first y-coordinate over the second x-coordinate minus the first x-coordinate".

Answer:

the answer is 0.204

Step-by-step explanation:

The probability that if 5 tires are inspected, exactly 1 has a defect is 0.204

The probability that a tire is defect is given as:

p = 5%

The required probability is then calculated using:

[tex]P(x) = ^nC_x * p^x * (1 - p)^{n - x}[/tex]

Where:

n = 5 --- number of tires

x = 1 ---number of tires with defect

So, we have:'

[tex]P(1) = ^5C_1 * (5\%)^1 * (1 - 5\%)^{5 - 1}[/tex]

This gives

[tex]P(1) = 5 * (5\%) * (1 - 5\%)^4[/tex]

Evaluate the product

P(1) = 0.204

Hence, the probability that if 5 tires are inspected, exactly 1 has a defect is 0.204

Answer:

a. $250

b. The total cost for x month is $200 + $50 × x

c. Please see the attached graph

d. Yes, there is a proportional relationship between time and the cost of the cell phone plan

e. $350

Step-by-step explanation:

The given parameters are;

The costs to start on the cell phone cell = $200

The charge each month = $50

a. The total cost to use the cell phone plan for 1 month = Start up fee + Monthly charge = $200 + $50 = $250

b. The total cost for x month, c = $200 + $50 × x

c. Please see the attached graph

d. Yes, there is a proportional relationship between time and the cost of the cell phone plan

e. The line parallel to the line graphed that goes to the point (0, 350), is given as follows;

y = m·x + c

Where;

m = 50

y - 350 = 50 × (x - 0)

y = 50·x + 350

The startup fee is given by the total cost at x = 0, when the monthly fee is excluded, which gives;

c = 50 × 0 + 350 = 350

The startup fee for the pricing plan = $350.

The startup fee and monthly cost for this plan according to the question is :

Part a:

The total cost to use the cell phone plan for 1 month = Start up fee + Monthly charge

Part b:

Please see the attached graph

Part c:

Yes, there is a proportional relationship between time and the cost of the cell phone plan .

Part e:

The line parallel to the line graphed that goes to the point (0, 350), is given as follows;

y = m·x + c

Where;

m = 50 y - 350 = 50 × (x - 0) y = 50·x + 350

The startup fee is given by the total cost at x = 0, when the monthly fee is excluded, which gives;

c = 50 × 0 + 350 = 350

Yes, there is a proportional relationship between time and the cost of the cell phone plan e. $350

The given parameters are; The costs to start on the cell phone cell = $200 The charge each month = $50

The startup fee for the pricing plan = $350.

divide both side by -5

x = -3

Answer:

x + 2y = 13}(add the both eqns)

-x + y = 5}

x +(-x) = 0

2y + y = 3y

13 + 5 = 18

then,

Answer:

6 goldfish = $4.50. You can buy 66 goldfish with $50

Step-by-step explanation:

We know that dozen is 12, so 12 goldfish would be $9. To find how much one goldfish costs we would divide 9 and 12. 9÷12 is 0.75. So one goldfish is $0.75.

To find 6 goldfish just multiply 0.75 to 6. 6 goldfish would be $4.50.

We know that 0.75 times 100 would be 75 so you can only buy less than 100 goldfishes. You can buy 66 goldfishes with $50.

Answer:

a = -13/35

Step-by-step explanation:

35a + 14 = 1

(given)

_________

35a + 14 = 1

- 14 -14

(subtraction property of equality)

(subtract 14 from both sides to isolate the 35a term)

_________

35a = -13

÷35 ÷35

(division property of equality)

(divide by 35 on both sides to remove the coefficient of 35 in 35a)

_________

a = -13/35

35a+14=1

35a+14 - 14 = 1 - 14

35a= -13

35a= -13

35a = -13

35       35

a= -13/35

Answer:

A partir del problemas vamos a crear una ecuación donde X es una docena de huevos y Y una libra de mantequilla

entonces: 4 docenas de huevos y 3 libras de mantequilla es igual a 14.100

en mi primera ecuación seria: 4X + 3Y = 14.100

ahora haremos la segunda ecuacion: tres docenas y 1 libra de mantequilla

en mi segunda ecuación seria: 3X + 1Y = 8.700 el plan es sumar las dos ecuaciones pero yo quiero que al sumarlas la variable "Y" desaparezca así que mi segunda ecuación la voy a multiplicar pór (-3) quedándome todo así:

primera ecuación: 4X + 3Y = 14.100

segunda ecuacion multiplicada por -3: -9X - 3Y = -26.1

al sumarlas obtengo como resultado: -5X = -12

resolviendo esa ecuacion obtengo que X=  

X=2.4

luego reemplazas X en la primera ecuación: 4X + 3Y = 14.100

reemplazando seria: 4 x (2.4) + 3Y =14.100

9.6 + 3Y = 14.1000

3Y= 14.100 - 9.6

Y=  

Y=1.5

entonces concluimos que la docena de huevos cuesta 2.4 $ y la libra de mantequilla 1.5 $

Answer:

I think it is 0.257 kg

Step-by-step explanation:

To change units from the gram to kilogram, you need to divide by 1000, because 1kg=1000g:

257÷1000= 0.257 Kg

The mass of the fruits in kilogram (kg) is 3.556 kg

Given:

Mass of the bag containing fruits = 3.813 kg

Mass of the empty bag = 257 g

convert

257 g to kg

257 g = 0.257 kg

Mass of the bc fruits = Mass of the bag containing fruits - Mass of the empty bag

= 3.813 kg - 0.257 kg

= 3.556 kg

Therefore, the mass of the fruits in kilogram is 3.556 kg

Answer:

AD=DC

Step-by-step explanation:

I just took the test, and it said that this is the correct answer.

Answer:

We have the equations:

1.15x + 0.65y = 8.90

and

x − 3y = -15

First, let's write them in the slope-intercept form:

The first one will be:

y = -(1.15/0.65)*x + 8.90/0.65  

The second:

y = (1/3)*x + 15/3 = (1/3)*x + 5.

then our system is:

y = -(1.15/0.65)*x + 8.90/0.65  

y  = (1/3)*x + 5.

To graph each line, you can just evaluate the line in two points (for x = 0 and x = 1, for example) and then locate those points in the coordinate axis, and then draw a line that connects them.

For example with the second line:

y(0) = (1/3)*0 + 5 = 5

then we have the point (0,5)

and

y(3) = (1/3)*3 + 5 = 8

Then we have the point (3,8)

With the first equation may be a little harder, as the coefficients are not whole numbers, we can rewrite it as:

y = (1.15/0.65)*x + 8.90/0.65  = (115/65)*x + (890/65)

Where i multiplied and divided by 100 the numerators and denominators in the right side, so now is easier to work with it.

The points you can use are:

y(0) =  (115/65)*0 + (890/65) = 13.7

the point is (0, 13.7)

and:

y(1) = (115/65)*1 + (890/65) = 15.5

The point is (1, 15.5)

Below you can see the graphs of both functions:

blue: y = -(1.15/0.65)*x + 8.90/0.65

red: y  = (1/3)*x + 5

The answer is in the picture below!
