Researchers were interested in whether thinking about success or failure causes differences in problem-solving performance. The researchers randomly assigned 10 people to think about three times when they successfully solved a problem and 10 people to think about three times when they failed to solve a problem. Everyone in the two conditions then solved as many anagrams as he or she could in 10 minutes.

I still struggle with defining these in some studies

Participants were randomly assigned to one of two groups. Each group was shown a photograph of a woman and was asked to rate how intelligent they thought she was on a scale from 1 to 10 (higher numbers = higher intelligence). The "no tattoos" group saw a picture of the woman without a tattoo; the "tattoos" group saw the same picture of the same woman, but with a tattoo added.

1.)What is the IV and the levels?

2,)What is the DV?

also discuss problems the method would address and problems the method would not address.

I have no idea where to start with this unit conversion process

How much money will it cost to buy 74.2 cm3 of tungsten knowing that tungsten has a density of 19.25 g/cm3

and the current price of tungsten in $13.74 / lb. (1 kg = 2.205 lb). Using sig figs

An empty graduated cylinder weighs 38.164 g. After 7.24 mL of an unknown liquid was added to the cylinder,

the cylinder weighs 43.272 g. What is the density of the unknown liquid?

is this faster than the speed of sound?

1 mile=1609 meters 1 hour=60 minutes 1 minute=60 seconds

Please help I don't know how to set this problem up, should be relatively simple.

Hi all just in need of some opinions on a good credible, and somewhat controversal article from a source such as those from CNN, Wall Street Journal, New York Times, The Economist, Newsweek, etc. Everyone has already done the DACA deal, and I need something juicy I can make a 2 min long schpeel over.

a.) Elections are the most visible form of political participation.

b.)Elections have the ability to grant legitimacy to those who serve as elected officials.

a.)are highly contested between Democrats and Republicans.

b.)yield higher turnout when held in "off-years".

c.)are nonpartisan

d.)result in "no-contest" elections due to gerrymandered districts.

If

y varies directly as the square root of

x and

y = 77 when

x = 441, find

y if

x = 194481. (Round off your answer to the nearest hundredth.)

If y varies directly as the square root of x and y = 24 when x = 9, find y if x = 81.

The gravitational force, F, between an object and the Earth is inversely proportional to the square of the distance from the object to the center of the Earth. If an astronaut weighs 199 pounds on the surface of the Earth, what will this astronaut weigh

100 miles above the Earth? Assume that the radius of the Earth is 4000 miles. (Round off your answer to the nearest pound.)

Plane A flies 2375 miles in the same amount of time it takes Plane B to fly 2600 miles. Plane B is flying 45 mph faster than Plane A. Find the amount of time it takes for each plane to travel their respective distances.

An inlet pipe on a swimming pool can be used to fill the pool in 20 hours. The drain pipe can be used to empty the pool in 21 hours. If the pool is 23 filled and then the inlet pipe and drain pipe are opened, how long from that time will it take to fill the pool?

Julie recently drove to visit her parents who live 240 miles away. On her way there her average speed was 25 miles per hour faster than on her way home (she ran into some bad weather). If Julie spent a total of 8 hours driving, find the two rates.
