Answer:
in △abc, the sides ab and ac are produced to ∠p and ∠q respectively. if the bisectors of ∠pbc and ∠qcb intersect at a point o. prove that ∠boc = 90 - ½ ∠a.
Answer:
4/15
Step-by-step explanation:
because 1/5÷3/4=4/15
61-34x98+90+21-4
We will put these in parenthesis to make it easier to read, and to mark what needs done first.
61-(34x98)+90+21-4
34x98=3,332
Now that the multiplication is done, we add and subtract.
90+21=111
61-3,332=-3271
-3271+111-4
We can reorder this to make it easier. Plus, we'll subtract -4 and -3271.
111-3275=-3164

Answer:
A) 0.0107
Step-by-step explanation:
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean and standard deviation , the z-score 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 p-value, we get the probability that the value of the measure is greater than X.
Mean of 440 seconds and a standard deviation of 40 seconds.
This means that
Find the probability that a randomly selected boy in secondary school can run the mile in less than 348 seconds.
This is the p-value of Z when X = 348. So
has a p-value of 0.0107, and thus, the correct answer is given by option A.
