From the question we are told that
The number of light produced in an hour is n = 922
The proportion of the bulb that are defective is p = 0.0334
Generally given from the question that we should use binomial distribution it then means that the standard deviation is mathematically evaluated as

From the given Venn diagram, the number of students who participate in at least 2 types of sports is
66 + 32 + 74 + 97 = 269
The total number of students is 824.
The percentage that participates in at least 2 type of sports (2 or more) is
100(269/824 = 32.6%
Answer: D. 32.6%
Answer:
hope this helps
Step-by-step explanation:
65% of 10,000
.65 * 10,000
6500
After one year-
10,000 +6500
16500
Subtract 100 from both sides
50x = 150 + 30x - 100
Simplify 150 + 30x - 100 to 30x + 50
Subtract 30x from both sides
50x - 30x = 50
Simplify 50x - 30x to 20x
20x = 50
Divide both sides by 20
x = 50/20
Simplify 50/20 to 5/2
<u>x = 5/2</u>
<em>In decimal: 2.5</em>
