Hey!!
here is your answer >>>
(Cube root 27 ) (cube root 64)
cube root of 27 is 3 and cube root of 64 is 4!.
now if we multiply them, we get
(3)(4)
12 !.
The answer is 12!.
Hope my answer helps!
Answer:
C. 59.01%
Step-by-step explanation:
Problems of normally distributed samples are solved using the z-score formula.
In a set with mean 
and standard deviation 
, the zscore of a measure X is given by:
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
In this problem, we have that:
What percentage of fourth graders are between 50 inches and 56 inches?
This is the pvalue of Z when X = 56 subtracted by the pvalue of Z when X = 50.
X = 56
has a pvalue of 0.8729
X = 50
has a pvalue of 0.2843.
0.8729 - 0.2843 = 0.5886, which is close to 59.01%.
So the correct answer is:
C. 59.01%
2(9-6)*2/18
2(3)*2/18
6*2/18
12/18
2/3

Answer:
Shaping
Explanation:
Shaping is the method of successively reinforcing closer and closer approximations to a target ultimate behavior. Shaping includes reinforcing responses which are approximating to the one needed. The shaping method is important because an individual is not always able to naturally exhibit the exact target behavior but by reinforcing the behavior closer to the target behavior, the terminal behavior can be learnt and taught. Shaping is carried out by successive approximation. This is done when the the target response is so rare that it will take a lot of time waiting for the response to take place so that it can be reinforced. In the given question Andy is rewarded every time his current grade C closely approximated to the desired goal that is A grade. So through these subtle reinforcements Andy's behavior is shaped.
The steps in shaping are:
- Reinforce any response which is close to the target terminal behavior in some way.
- Reinforce the response more closely associated and resembled with desired behavior. The previous behavior should no longer be reinforced.
- Continue reinforcing the responses that more closely approximates target behavior.
- Continue to reinforce the subsequent approximations until the desired behavior is met.
- Reinforce only the ultimate desired behavior once the desired behavior is reached.
Example:
Suppose a teacher wants her student give presentation in front of the whole class but the student is shy so he would not be capable of giving a presentation at once. So the student should be given rewards for his behaviors/responses that approximates closely to the desired goal. Such as giving him reward when he stands in front of class. Next, giving him reward when he introduces himself to the class at the start of presentation. Rewarding him when he tells the topic of the presentation. Ultimately he can give a presentation. Shaping can be achieved this way.
Answer:
2(x-6) < 27
Step-by-step explanation:
kewords: Twice, difference, less
Twice makes us write this: 2( )
Difference of a number and 6 (a number means variable) = 2(x-6)
less than 27 = 2(x - 6) < 27
