"At least" means ≥, which is greater than or equal to.
If Suzy scored at least 18 points, then make a variable, such as x, that represents the amount of points Suzy scored.
The inequality would be x ≥ 18.
If x is the amount of points scored and 18 is the minimum she scored, then this reads "Suzy scored greater than or equal to 18 points."
"At least" requires no less than but can be equal to the value.
So the answer is x ≥ 18.
Answer:
P = 10/171
P = 0.058
The probability that both fish selected are Catfish is 0.0058
Step-by-step explanation:
Given:
The tank contains;
Algae eaters = 8
Catfish = 5
Tilapia fish = 6
Total number of fish = 8+5+6= 19
To determine the probability that both fish selected are Catfish P;
P = 5/19 × 4/18
( The number of the total number of fishes, and Catfish reduce by one after each selection because it is selected without replacement)
P = 10/171
P = 0.058

Step-by-step explanation:
Answer:
5/7 hours per birdhouse
Step-by-step explanation:
If you want "hours per birdhouse", divide the number of hours by the number of birdhouses. ("Per" essentially means "divided by" in this context.)
(5 hours)/(7 birdhouses) = (5/7) hours/birdhouse
