Mila is deciding between two parking garages. Garage A charges an initial fee of $7 to park plus $4 per hour. Garage B charges an initial fee of $3 to park plus $5 per hour. Let AA represent the amount Garage A would charge if Mila parks for tt hours, and let BB represent the amount Garage B would charge if Mila parks for tt hours. Write an equation for each situation, in terms of t,t, and determine the interval of hours parked, t,t, for which Garage A is cheaper than Garage B.

Answer:

Store A has the better deal

Step-by-step explanation:

People would see that 7 pounds of bananas is worth 7$ and would buy from store A instead of store B for selling a lesser amount for almost the same price.

Answer:

8 + 5 + 7 =20

Step-by-step explanation:

Answer: Yes

Step-by-step explanation: We're going to have to substitute

in the coordinates of that ordered pair into the equation.

I am going to substitute in the x and substitute in the y.

So it's really 5(2) + 3(-3) = 1.

From here it should be pretty straightforward,

all we are doing is evaluating the statement.

Simplifying on the left we have 10 + -9 = 1 or 1 = 1.

Now we know that the ordered pair (2, -3) satisfies this equation.

.........

Answer:

Step-by-step explanation:

f(n + 1) = f(n) + 2.5

f(1) = -10

f(2) = f(1) + 2.5 = -10 + 2.5 = -7.5

f(3) = f(2) + 2.5 = -7.5 + 2.5 = -5

f(4) = f(3) + 2.5 = -5 + 2.5 = -2.5

Answer:

The decision rule is  

Fail to reject the null hypothesis

 The conclusion is  

There is no sufficient evidence to show that  the  designer's claim of a better shoe is supported by the trial results.

Step-by-step explanation:

From the question we are told that

  The population mean is  [tex]\mu = 15 \ months[/tex]

   The sample size is  n =  25

   The sample mean is  [tex]\= x = 17 \ months[/tex]

   The standard deviation is  [tex]s = 5.5 \ months[/tex]

Let assume the level of significance of this test is  [tex]\alpha = 0.05[/tex]

    The null hypothesis is  [tex]H_o : \mu = 15[/tex]

     The alternative hypothesis is  [tex]H_a : \mu > 17[/tex]

Generally the degree of freedom is mathematically represented as  

         [tex]df = n -1[/tex]

=>       [tex]df = 25 -1[/tex]

=>       [tex]df = 24[/tex]

Generally the test statistics is mathematically represented as

        [tex]t = \frac{\= x- \mu }{\frac{s}{\sqrt{n} } }[/tex]

=>   [tex]t = \frac{ 17 - 15 }{\frac{5.5}{\sqrt{25} } }[/tex]

=>   [tex]t = 1.8182[/tex]

Generally from the student t distribution table the probability of obtaining   [tex]t = 1.8182[/tex] to the right of the curve at a degree of freedom of [tex]df = 24[/tex]  is  

    [tex]p-value = P(t > 0.18182 ) = 0.4286[/tex]

From the value obtained we see that  [tex]p-value > \alpha[/tex] hence

The decision rule is  

Fail to reject the null hypothesis

 The conclusion is  

There is no sufficient evidence to show that  the  designer's claim of a better shoe is  supported by the trial results.

Answer:

The plane is traveling at 160 km/h

Step-by-step explanation:

This is because if the first plane is traveling at 160 and flies for 5 hours it'll travel 800 km. then the second plane will have to catch up in 4 hours since it left an hour late, this means traveling at 160 km with an extra 40 km in 4 hours will get it to the first plane at 800 km in the 4 hours given

Step-by-step explanation:

Let R be region in the xy-plane and β>0 be the constant. What is the region R that will minimize the value of integral (x² + y² - β²).

i.e.

[tex]\int \int _R (x^2 +y^2 - \beta^2) \ dA[/tex]

Answer:

0

Step-by-step explanation:

Given that:

[tex]\int \int _R (x^2 +y^2 - \beta^2) \ dA[/tex]

where;

R is the region in the xy-plane.

To minimize our double integral, we have to determine the region over which the function we are integrating has a negative value.

x² + y² - β²  ≤ 0 ; where β > 0 is a constant

x² + y²  ≤ β² is the  circle with center (0,0)

Radius "β" because  R: x² + y²  ≤ β²

The polar coordinates: x = rcosθ and y = rsinθ

x² + y² = r²

⇒ r limits : r = 0 → β

⇒ θ limits : r = 0 → 2π

[tex]\iint_R(x^2+y^2-\beta^2) \ dA =\int\limits ^{2 \pi}_{\theta=0} \int \limits ^{\beta}_{r=0}( \beta^2 -\beta^2) \ rd \ rd\ \theta[/tex]

[tex]\int \int _R (x^2 +y^2 - \beta^2) \ dA[/tex] = 0

Answer:

She should receive $30.86

Step-by-step explanation:

$7.05 + $8.12 + $3.97 =19.14

50 - 19.14 = 30.86

Using the subtraction method we have found that Hannah will receive the change of $30.86

Subtraction is an arithmetic operation that represents the operation of removing objects from a collection

Total cost of three items =7.05 + 8.12 + 3.97 =$19.14

She paid $50 bill

Change that Hannah should receive is =50 - 19.14 = $30.86

Hence, change that Hannah should receive is$30.86
