Seed are often treated with fungicides to protect them in poor draining, wet environments. A small-scale trial, involving five t

reated and five untreated seeds, was conducted prior to a large-scale experiment to explore how much fungicide to apply. The seeds were planted in wet soil, and the number of emerging plants were counted. If the solution was not effective and four plants actually sprouted, what is the probability that : a) all four plants emerged from treated seeds? b) three or fewer emerged from treated seeds? c) at least one emerged from untreated seeds?

The sum of 7 and three times a number is at least 13
Yuki888 [10]

Answer:

7 + 3x ≥ 13

Step-by-step explanation:

The best way to write this is to truly understand what each of the terms mean. The sum means that multiple terms are added together, which means that 7 and 3 times a number will be added together.

Next, the term three times a number just means 3x. So as of now, we have 7 and 3x being added together.

Finally, the term at least 13 means that the 7 + 3x is greater than or equal to 13. Once everything is put together, you get a final inequality of 7 + 3x ≥ 13.
