WINSTONCH [101]2 years ago
5 0

Answer:

b

Step-by-step explanation:

Take 1/2 off of the 31 1/12 to make it easier. That gives you 31 and 4. Then take one away from both numbers to get to 30 and 3. 30 minus 3 is 27.

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

A 14-ounce box of cereal sells for $2.10. What is the unit rate?
Ahat [919]

Answer:

The unit rate is equal to 0.15\frac{\$}{ounce}

Step-by-step explanation:

we know that

The unit rate is the ratio of two measurements in which the second term is equal to one

In this problem to find the unit rate, divide the total cost of cereal by the total weight of cereal

so

\frac{2.10}{14}\frac{\$}{ounces} =0.15\frac{\$}{ounce}

therefore

The unit rate is equal to 0.15\frac{\$}{ounce}

Which is the focus of a parabola with equation y2 = 4x?
statuscvo [17]

Answer:

(1, 0)

Step-by-step explanation:

Please write this as y^2 = 4x; the " ^ " indicates exponentiation.

The appropriate equation for a horizontal parabola that opens to the right is

y^2 = 4px

Here, we are told that  y^2 = 4x; this tells us that 4p = 4, and so p = 1.  

Again, this parabola is a horizontal one and it opens to the right.  p = 1 is the distance of the focus from the vertex, and in this case p = 1.  Thus, the focus is at (1, 0) (situated on the x-axis).
