Answer:
b. 0.12
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:
What is the probability that a seed will take more than 720 hours before germinating?
This is 1 subtracted by the pvalue of Z when X = 720. So
has a pvalue of 0.88.
1 - 0.88 = 0.12
So the correct answer is:
b. 0.12
The answer is D. 60'. You add both angles together, then subtract them from 180.
60+70=120
180-120=60
This question is based on logic.
As given, there are three friends, Jose, Michael, and Andrea. They are playing a game where each decides to be either a liar or a truth teller. A liar must always lie and a truth teller must always tell the truth.
As Michael stated, "Jose said that he is a liar." this means Michael is a truth teller because as per the game rule, he is telling the truth. So this gives Jose as a liar.
Andrea said, " If one of us is a liar, then we are all liars." This makes Andrea a liar as Michael's statement already proved that he is the truth teller.
Hence, Michael is a truth teller and Jose ans Andrea are liars.
The smallest of the three consecutive integers is 24.
<h3>How to solve algebraic word problems?</h3>
Let the 3 consecutive integers be;
x, y and z
Thus;
y = x + 1
z = x + 2
Now, we are told that their sum is equal to 4 times the largest number minus 29. Thus;
x + x + 1 + x + 2 = 4(x + 2) - 29
3x + 3 = 4x + 8 - 29
4x - 3x = 3 + 21
x = 24
Thus, we can conclude that the smallest of the three consecutive integers is 24.
