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

I a failin really need help
Ad libitum [116K]
It is no. You need to figure out the missing angles. You can take 97 and 35 from the yellow triangle and add them up to equal 132. Take 180 and subtract 132 to find the missing angle, which would be 48. The angle 48 compares to the 47 in the green triangle. Since they are not the same, they are not similar.

Find the perimeter of the figure to the nearest hundredth
Ghella [55]

Answer: 33.13 in

Step-by-step explanation:

First, let's start with the perimeter of the semicircles.

Since there are two, it is easier to do because the perimeter of the two halves will add to one full circle; so we can just calculate without having to halve anything.

The formula for the perimeter (aka circumference) of a circle is 2πr

Plug the radius into the equation to get 2π4, or 8π

8π ≈ 25.13

The perimeter of the rectangle is 6(4) = 24.

We now have to subtract the diameters of the circles, as they are not on the outside of the figure and won't be counted in the total perimeter. From the 24, we subtract the two diameters, or 16 in.

24 - 16 = 8

The total perimeter then comes out to be 25.13 + 8, or 33.13 in
