Answer:

0.88

Step-by-step explanation:

P(x≥2) = P(x=2) + P(x=3) + P(x=4) + P(x=5) + P(x=6)

P(x≥2) = 0.21 + 0.35 + 0.21 + 0.06 + 0.05

P(x≥2) = 0.88

Or, you can calculate it as:

P(x≥2) = 1 - P(x=1) - P(x=0)

P(x≥2) = 1 - 0.09 - 0.03

P(x≥2) = 0.88

Answer:

Step-by-step explanation:

1. cannot be determined. We don't have all the numbers so you can't find the mean (average).

2. True. The median is the line in the middle of the box. The median for movie 1 is greater than 600 and the median for movie 2 is less than 600.

3. True. Interquartile range is the biggest number of the box minus the smallest number of the box. Movie 1 is approximately 200 and movie 2 is approximately 70.

4. True. Q3 is the last line of the box.

Answer:

from April to May is 17%

from May to June is 29%

Step-by-step explanation:

24.  

April   30 hr * 6.5 = 195

May  35 * 6.50 = 227.50

percent increase = (new-original)/original

                               (227.5 - 195)/195

                            = 32.50/195

                             .166666

to change from decimal to percent , multiply by 100

  = 16.67%

round to the nearest whole percent

=17%


b) May  35 * 6.50 = 227.50

  June  45* 6.50 = 292.50

percent increase = (new-original)/original

                                = (292.50-227.50)/227.50

                               = 65/227.50

                              =.285714

to change from decimal to percent , multiply by 100

28.57 %

round to the nearest whole percent

29%
