Answer:
of favourable events = 4, (which includes 1, 4, 9, 16). And, total number of observations are 20. So, the probability of picking a square number between 1 and 20 is 1/5.
Step-by-step explanation:
Answer:
the fourth option is correct
t = 29
we know this bc you have to distibute the parthentesis and then solve the rest of the equation
Question asked:Jacob and Sarah are saving money to go on a trip. They need at least $1975 in order to go. Jacob mows lawns and Sarah walks dogs to raise money. Jacob charges $25 each time he mows a lawn and Sarah charges $15 each time she walks a dog. The number of dog walks that Sarah has scheduled is no more than four times the number of lawns Jacob has scheduled to mow. Sarah will walk at least 50 dogs.Write a set of constraints to model the problem, with x representing the number of lawns mowed and y representing the number of dogs walked.
My answer:
They need at least $1975. Jacob charges $25 each time he mows a lawn and Sarah charges $15 each time she walks a dog.
25x + 15y ≥ 1975
The number of dog walks that Sarah has scheduled is no more than four times the number of lawns Jacob has scheduled to mow.
y ≤ 4x
Sarah will walk at least 50 dogs.
y ≥ 50

1. Subtract 8 from both sides
2. Simplify to get x= -23
