Answer: Two column proof.
Explanation :
A two-column proof is one common way to organize a proof in geometry.Two-column proof always has two columns where one for statements and one for reasons.
Here,
is a right angle and
is a straight angle(
) . (given)
Therefore, must be right angle. ( because,
)
Which is the required proof.
Since, In the above proof both statements and reasons both mentioned, therefore, it is the two column proof.
Note: We can also make a table which consist of two columns, in first we can mention 'statements' while in second column we can mention 'reasons'.
Answer:
99.87% of the store’s total delivery orders will be delivered to consumers with charge
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:
If a pizza store’s policy is, "Orders delivered within one hour or they’re free!", what percentage of the store’s total delivery orders will be delivered to consumers with charge?
Within one hour, which is 60 minutes. So this is the pvalue of Z when X = 60.
has a pvalue of 0.9987
99.87% of the store’s total delivery orders will be delivered to consumers with charge
