Mary used a sample of 68 large U.S. cities to estimate the relationship between Crime(annual property crimes per 100,000 persons

) and Income (median annual income per capita, in dollars). Her estimated regression equation was Crime = 428 + 0.050 Income. If Income decreases by 1000, we would expect that Crime will:
decrease by 50
Go up by 428
increase by 50
Remain unchanged

Answer:

Decrease by 50.

Explanation:

Estimated regression equation was:

Crime = 428 + 0.050 Income

Above regression equation says that if there is an increase in the income level by $1 then as a result crime increases by 5% which shows that there is a direct relationship between the income level and crime level.

Hence, if Income decreases by 1000, then we would expect that Crime will decreases by:

= 0.050 × 1,000

= 50

Decrease by 50.

Determine what type of model best fits the given situation: the value of a classic car is presently $50,000 and is increasing in
jok3333 [9.3K]

The model that best fits the given situation is exponential  

<h3>what is an Exponential Function?</h3>

Exponential function, in mathematics a relationship of the form y = a^{x}, where the independent variable x extends over the entire real number line as an exponent of a positive number a. The most important exponential function is y = e^{x}.    

Here,

The value of a classic car = $50,000

It is increasing in value by 5% per year.

So, here we have a = 50,000 and x = 5%

The function is increasing.

b = 1+5%

b = 1+0.05 = 1.05

Hence, the function that describes this situation is given by:

f(x)=50000(1.05)^{x}

Supply costs at Lattea Corporation's chain of gyms are listed below: Client-Visits Supply Cost March 11,665 $28,579 April 11,461
mario62 [17]

Answer:

<em>$0.48 per client-visit; $22,856 per month</em>

Explanation:

Where,

y2 is the total cost at highest level of activity;                                                                       y1 is the total cost at lowest level of activity;                                                                      x2 are the number of units/labor hours etc. at highest level of activity; and                           x1 are the number of units/labor hours etc. at lowest level of activity

<em>Variable Cost per Unit </em>

= (28,904 -28,227) / (12,600-11,199)

= $0.48

<em> Total Fixed Cost </em>

= y2 ? bx2

= 28,904 - $0.48 * 12600

= $22,856.00

gulaghasi [49]

Answer:

No, he doesn't show diminishing marginal utility. Yes, he shows increasing marginal utility for Coke.

Explanation:

The law of diminishing returns states that the marginal or addition satisfaction or utility derived from the consumption of a product increase until a pint and then starts to  decrease.

Units         Total utility       Marginal utility

1                    10                          10        

2                   25                         15                    

3                   50                         25

After 3 bottles, John does not show diminishing marginal utility as the marginal utility (as shown above) continues to increase with each additional bottle of coke consumed.
