So, the first cake needs x cups of flower. The second x+1/2 and the third 2x

in total this is x+x+1/2+2x=4x+1/2.

this is equal to<span>8/1/2

soo

4x+ \frac{1}{2} =8 \frac{1}{2}
</span>
4x= 8 \frac{1}{2}- \frac{1}{2}
4x=8
x=2

this is the first cake, the second will have 2\frac{1}{2}

and the last one twice as much as the first, so 4

let's check

2+2.5+4=8.5 correct!

zepelin [54]

Answer:

75%

Explanation:

In order to understand this question you need to understand the matching law first. The matching law provides the density of reinforcement or the rate of reinforcement if more than one response is available simultaneously to the individual. Here, two responses are available which are left key, 60 reinforcers per hour, and right key, 20 reinforcers per hour. This provides the ratio between the two reinforcers which is 60:20 or 3:1 in favor of left key. Here, one has to make a prediction only for left key and based on 3:1 ratio it can be said that 75% of pigeon will make their responses on the left key.

In order to test a nondirectional hypothesis, a researcher would use a __________ test. A. one-tailed B. alternative C. critical
Nady [450]

Answer:

C. Critical

Explanation:

A non-directional hypothesis talks about how an independent variable has an effect on the dependent variable. The direction of the effect isn’t a definite one.

This form of hypothesis would entail the use of a critical test to ascertain its authenticity due to the effect not being a definite one. This means extra tests and caution are employed in this case.

This is why critical tests is the right choice.
