Answer:
Underfined
Step-by-step explanation:
There are no values of
x
that make the equation true.
Undefined
1)√3 = 1.73 (near +2 left)
2)√10 = 3+something (near +3, towards RHS)
3)√26 = 5+something (near +5, towards RHS)
4)-√5 = -2-something (near -2 towards left)
5)-√14 = -4+something (near -4 towards right)
The expected count of visits is the mean or average visits to each feeder
The expected count of visits to the third feeder is 87.5
<h3>How to determine the expected count of visit?</h3>
The table of values is given as:
Feeder 1 2 3 4
Observed visits 80 90 92 88
In this case, the null hypothesis implies that the visits to each feeder are uniformly distributed
So, the expected count is calculated using:
Expected count =Visits/Feeders
This gives
Expected count = 350/4
Evaluate the quotient
Expected count = 87.50
Hence, the expected count of visits to the third feeder is 87.5

Answer:
A
Step-by-step explanation:
Given
(3x² - 11x - 4) - (2x² - x - 6)
Distribute both parenthesis, noting the second is distributed by - 1
= 3x² - 11x - 4 - 2x² + x + 6 ← collect like terms
= x² - 10x + 2 ← this is a quadratic with 3 terms, thus trinomial → A
Answer:
The answer should be 150 x .20 = 30m/s
