I would go for Obtuse from the 120° angle, Acute from the either the 20° and 40°, and scalene since all angles are unequal
compare the divisor x-3 with x-a which will give a=3 and then use remainder theorem.
Answer:
P(X < 80) = 0.89435.
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:

P(X < 80)
This is the pvalue of Z when X = 80. So



has a pvalue of 0.89435.
So
P(X < 80) = 0.89435.
Answer:
720.
Step-by-step explanation:
1*2*3*4 * 5*6
= 24 * 30
= 720.
Splitting it up in this way makes it easier.
