Answer:
59.5
Step-by-step explanation:
Fig = square + triangle
Area of square = s x s = 7^2 = 49 sq.cm
Area of triangle = 1/2 bh = 1/2 x 3 x 7 = 10.5 sq.cm
Area of fig = area of sq + area of triangle = 49 + 10.5 = 59.5 cm^2
I hope im right!!
Answer:
The score that cuts off the bottom 2.5% is 48.93.
Step-by-step explanation:
When the distribution is normal, we use 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 question, we have that:
What is the score that cuts off the bottom 2.5%
This is X when Z has a pvalue of 0.025, so X when Z = -1.96.
The score that cuts off the bottom 2.5% is 48.93.
I believe its the first four after the decimal
You multiply 5 times 8 so that will give you 40, so the answer is 40
The third one shows parallel lines cut by a transversal
