Luis wants to buy a skateboard for $79.99. All merchandise is discounted 12%. What is the total cost of the skateboard if Luis h
VikaD [51]
First you need to figure out the cost of the skateboard after the discount but before the sales tax. By doing 100%-12% you figure out how much of the original cost you are paying 88%. Then you multiply 79.99(original cost) and 88%(how much you pay) which gets you 70.39. Then you figure out the sales tax by multiplying 70.39 by 6.75% which gives you 4.75(the sales tax). And the last thing you need to do is add the cost before tax(70.39) and the tax(4.75). 
The skateboard costs $75.14

The following statements are true;

The expression 23h represents the total charge for  Elegance Home Painting.

If José hires the painters for 10 hours, then Elegance  Home Painting will be cheaper.

If José hires the painters for 20 hours, then Krystal Klean  Painting will be cheaper.

Step-by-step explanation:

Given,

Amount charged by Krystal Klean painting to come out = $175.00

Per 30 minutes charges = $7

1 hour charges would be $14.

Let,

h be the number of hours.

Total cost for Krystal Klean = 14h + 175

Amount charged by Elegance per hour = $23

Total cost = 23h

The expression 23h represents the total charge for  Elegance Home Painting.

As Jose will choose from both painters, therefore, he will only hire one.

For 10 hours;

h = 10

Krystal Klean;

Total charges = 175 + 14(10)

Total charges = 175 + 140 = $315

Elegance Home;

Total charges = 23(10) = $230

If José hires the painters for 10 hours, then Elegance  Home Painting will be cheaper.

For 20 hours;

h = 20

Krytal Klean,

Total charges = 175 + 14(20) = $455

Elegance Home = 23(20) = $460

If José hires the painters for 20 hours, then Krystal Klean  Painting will be cheaper.

ioda

Answer: inductive argument.

Step-by-step explanation:

Deductive argument is a logical argument in which a conclusion is made upon the given premises which are assumed to be true.

inductive argument works on the basis of a series of observation and then bring it to frame a certain conclusion.

Here, Flanagans are considering the observation they made by previous children (i.e. they are athletically gifted) and applying the same on the new one by saying "youngest child is bound to be athletically gifted as well.".

So it is of-course an inductive argument.

Ivanshal [37]

Answer:

The best fit line is a regression line explaining relationship between dependent & independent variables, minimising the residual differences between observed values & actual values of dependent variable.

Step-by-step explanation:

Regression is a statistical process that explains relationship between dependent variable & independent variable(s). Scatter plot depicts the regression relationship between the variables in a graphical form.

Scatterplot showing snowfall measured in inches : is a graphical depiction of - regression relationship between snowfall as a dependent variable with its explanatory (independent) variables ; like temperature, humidity , other climate & weather factors etc.

The line of best fit would be a regression line (scatterplot), which describes the relationship of snowfall with its above mentioned explanatory variables, in such a way that the estimated value of snowfall is closest possible tothe actual values of snowfall (i.e their difference is minimum).
