Designer Dolls, Inc., found that the number N of dolls sold varies directly with their advertising budget A and inversely with t
denis-greek [22]

here we are told that

number of dolls sold varies directly with advertising costs

number of dolls varies inversely with price of a doll


so initially

1800 dolls sold when advertising costs were $ 34 000

and price of a doll was $ 25


next they increased the advertising costs to $ 42 000

as we know number of dolls sold varies directly with advertising costs

so here when the advertising costs increase the number of dolls sold too should increases as its directly proportional relationship


we arent told that the price of a doll is changed so there's no effect on the number of dolls sold due to changes in price of a doll


only effect on number of dolls sold is due to increase in advertising costs

increase in advertising cost leads to increase in number of dolls sold


from the given options, only in one option the number of dolls sold are more than 1800 dolls. option is C with 2224 dolls


therefore correct answer is C. 2224 dolls

The sum of three and seven times a number is -74. What is the number?
Dima020 [189]
<h3>♫ - - - - - - - - - - - - - - - ~Hello There!~ - - - - - - - - - - - - - - - ♫</h3>

➷ Form an equation with 'x' as the unknown number

7x + 3 = -74

Subtract 3 from both sides:

7x = -77

Divide both sides by 7:

x = -11

The number is -11

The table below shows the outputs y for different inputs x:
Nutka1998 [239]
         Part A: The table does not represent y as a function of x. We can not input 1 and get 4 and 2 as outputs ( or input 3 and get 12 and 6 as outputs ).
         Part B : f (120) is a cost for renting a peddleboat for 120 hours;
         f (120) = 20 + 10 * 120 = 20 + 1,200 = 1,220.

The mean annual income for adult women in one city is $28,520 and the standard deviation of the incomes is $5600. The distributi
pshichka [43]

Answer:

E(\bar{x}) = 28520

Standard error of mean = 689

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = $28,520

Standard Deviation, σ = $5600

Mean of sampling distribution =

E(\bar{x}) = \mu = 28520

As per Central Limit Theorem, if the sample size is large enough, then the sampling distribution of the sample means follow approximately a normal distribution.

Sample size, n = 66

Since the sample size is large, we can use normal distribution for approximation.

Standard error of mean =

\displaystyle\frac{\sigma}{\sqrt{n}} = \frac{5600}{\sqrt{66}} = 689.31 \approx 689
