Answer:
0.62% probability that a randomly selected person scores above 125 on the IQ test
Step-by-step explanation:
Problems of normally distributed samples can be 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 is the probability that a randomly selected person scores above 125 on the IQ test
This is 1 subtracted by the pvalue of Z when X = 125. So
has a pvalue of 0.9938
1 - 0.9938 = 0.0062
0.62% probability that a randomly selected person scores above 125 on the IQ test
In the given question, most of the information's are of immense importance. based on these information's, the required answer to the question can be found. It is already given that the car releases 19.6 pounds of carbon dioxide for 1 gallon of gasoline. The amount of carbon dioxide released for 14.5 gallons of gasoline needs to be found.
So
Amount of carbon dioxide released by
1 gallon of gasoline = 19.6 pounds
Then
Amount of carbon dioxide released by
14.5 gallons of gasoline = (19.6 * 14.5) pounds
= 284.2 pounds
So an estimated 284.2 pounds of carbon dioxide will be released by 14.5 gallons of gasoline.
Noah , because the ratio of powder to water is a good amount
If Δ ABC is similar to ΔLMN, then angle A corresponds with angle L, B corresponds to angle M and C corresponds to N.
The sum of angles in a triangle add up to 180.
Therefore, angle A = 180- (95 +35)
= 50
but, corresponding angles are equal;
Hence angle L = 50°
Answer:
113
Step-by-step explanation:
area of a circle is 3.14*r^2
r=d/2 r=6
3.14*36=113
