Determine whether more or less than the percent budgeted was actually spent.
SSSSS [86.1K]

The amount spent as a percentage of the budget can be found from

... (actual amount)/(total budget) × 100%

... = (actual amount)/3600×100%

... = ((actual amount)/36)%

For housing, this is

... (820/36)% = 22.78% . . . . less than budget for housing

For transportation, this is

... (370/36)% = 10.28% . . . . more than budget for transportation

-5.8c+4.2-3.1+1.4c−5.8c+4.2−3.1+1.4c
Snowcat [4.5K]

Answer:

-10.2c + 2.2

Step-by-step explanation:

To make things less complicated, write down everything separate from the other. Then group together the intercepts and the coefficients into separate groups. After that, add them up separately in a format to where it will look like basic addition.

Hope this helps. I also apologize for any errors.

A major airline company is concerned that its proportion of late arrivals has substantially increased in the past month. Histori
lutik1710 [3]

Answer:

The correct statement is  

The  null hypothesis is  H_o  :  p =  0.18

The alternative hypothesis is  H_a :  p >  0.18

Step-by-step explanation:

From the question we are told that

    The population proportion is  p  =  0.18  

    The  sample size is  n  =  1240 airplane

     The  number of airplane is  k  =  310

 

Generally the sample proportion is  

      \^ p = \frac{k}{n}

=>   \^ p = \frac{310}{1240}

=>   \^ p =0.25

The  null hypothesis is  H_o  :  p =  0.18

The alternative hypothesis is  H_a :  p >  0.18
