The study results show that 29% of consumers indicate that in dash appin-app recommendations would drive them to add more items to their cart and that 3838% would spend more time in the appin the app. But shopper priorities change the moment they need help; they expect to get it immediately and effortlessly. If forced to stop what they're doing and leave the appapp to get help, 1 out of 55 shoppers would likely not make a purchase with the brand at all. The research is based on an online survey with a sample of 1 comma 1,800 U. S. adults who have made purchases via their mobile devicetheir mobile device. Complete parts (a) through (d) below. Describe the sample that was collected.
A. The sample includes only the 684684 consumers that indicated that in dash appin-app recommendations would drive them to add more items to their cart.
B. The sample includes all U. S. adults who make purchases via their mobile devicetheir mobile device.
C. The sample includes only the 522522 adults that would spend more time in the appin the app.
D. The sample includes the 1 comma 8001,800 U. S. adults who made purchases via their mobile devicetheir mobile device.

D. The sample includes the 1,800 U.S. adults who made purchases via their mobile device

Step-by-step explanation:

The survey showed that it was based on a sample of 1,800 US adults who have made purchases via their mobile phones so D is correct.

A is incorrect because 29% of the sample is 522 people not 684. Also the sample includes more people than only those who indicated that app recommendations would drive them to add more items to their cart.

B is wrong because this is a sample so it cannot include ALL US adults who make purchases via their mobile devices.

C is also incorrect because 38% of the sample is 684 people not 522. Also the sample includes more people than those who would spend more time in the app.

5x+40

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x
