The equation is a + 9 = 15
Step-by-step explanation:
Let the number be 'a'
Given that,
A number plus 9 is 15
So,
a + 9 =15
a = 15 - 9
a = 6
The equation needed is,
a + 9 = 15
What’s the the math problem? I don’t see it..
Using the discrete distribution, it is found that the probability that it offers an even number of honors classes is of 0.68.
<h3>What is the discrete probability distribution?</h3>
The distribution for the number of honors classes the school offers is given by:
Hence the probability of an even number is given by:
P(even) = P(X = 0) + P(X = 2) + P(X = 4) = 0.38 + 0.25 + 0.05 = 0.68.
