The problem statement says λ<1. If this is true, then the cannonball is slower than the boat, and it will never reach the boat. So I assume it's actually λ>1.

If we say t is the amount of time, then the boat travels south a distance of ut, and the cannonball travels a distance of λut.

v = λut

ut = v/λ

Using Pythagorean theorem:

d² + (ut)² > v²

d² + (v/λ)² > v²

λ²d² + v² > λ²v²

λ²d² > (λ² − 1) v²

λ² / (λ² − 1) > (v/d)²

A random sample of 240 park users were asked if they go to the park more often on weekdays or on the weekend. The results are sh

docker41 [41]

Answer:

False

True

False

Step-by-step explanation:

Weekdays Weekend

Male 50 10

Female 150 30

The males go to the park more often on the weekend.

This is false Males go more on the weekdays 50 vs 10

The females go to the park more often on weekdays.

True Females go on the weekdays 150 to 30

For the participants in the survey, gender affects which days of the week a person goes to the park.

False, they both go to the park more on the weekdays

Males 50 to 10 on the weekdays which simplifies to 5 to 1

Females 150 to 30 which simplifies to 150/30 to 30/30 or 5 to 1

It is equal
