Answer:

A control should have been included in the investigation  

Explanation:

It is impossible for the student to interpret a correct conclusion about his experiment, without adding a control treatment where he can really compare the differences between the variables.

Control treatment is an element of research that receives all factors, except the variable being tested. The control serves to make comparisons with the other treatments, allowing to observe the exact difference between a system where the variable was tested and the system where it was not.

In the case of the question above, it would have been necessary for the student to have placed a cart on a ramp of normal height and without sandpaper. That way he could compare the speed between this cart and the carts on the other ramps, thus having a correct result.

The legal authority of a salesperson normally is the same as that of a buyer. To solicit orders and get ratification and acceptance from his or her employer.

That is the reason why a salesperson is hired for. He/she interacts with the consumer, offers the best deal possible according to the indications of the manager of the store, he/she offers a good explanation of the benefits of the product, answer questions, and generally treat the consumer in the best way possible to make it back soon and if its possible, create loyalty to the store. If the salesperson does a good job, it is rewarded. If not, some consequences could be legal in the case of a thief.

Where did the symbols for the democratic and republican parties come from?
shusha [124]

Answer:

Jackson, a hero of the War of 1812 who later served in the U.S. House of Representatives and U.S. Senate, was amused by being called a jacka** from his opponents, and included an image of the animal in his campaign posters. He later went on to defeat incumbent John Quincy Adams, and serve as America’s first Democratic president. In the 1870s, influential political cartoonist Thomas Nast helped popularize the donkey as a symbol for the Democratic Party. For the republican party, it was formed in 1854 and six years later Abraham Lincoln became its first member elected to the White House. An image of an elephant was featured as a Republican symbol in at least one political cartoon and a newspaper illustration during the Civil War.

Hope this helps and have a nice day!
