The decline of salmon fisheries along the Columbia River in Oregon has caused great concern among commercial and recreational fishermen. The paper 'Feeding of Predaceous Fishes on Out-Migrating Juvenile Salmonids in John Day Reservoir, Columbia River' (Trans. Amer. Fisheries Soc. (1991: 405-420)) gave the accompanying data on
y= maximum size of salmonids consumed by a northern squaw fish (the most abundant salmonid predator) and
x= squawfish length, both in mm.
Use the following statistics to give the equation of the least squares regression line.
x=524.880,
y=413.975,sx=12.251,sy=12.300,
r=0.9562
options:
a) ^y=0.960xâ89.910
b) ^y=0.960x+89.910
c) ^y=â89.910x+0.960
d) ^y=0.952x+89.910
e) ^y=0.952xâ89.910
f) None of the above
Answers
Answer:
the correct answer is not there. here it is:
^y = 0.960x - 89.910
Step-by-step explanation:
we have regression line equation as:
^y = a+bx
we have the following details available
x = 524.88
y = 413.975
Sx = 12.251
Sy = 12.300
r = 0.9562
we have to find values of a and b
b = rSy/Sx
= 0.9562(12.3)/12.251
= 11.76126/12.251
= 0.960
a = y - intercept
= 413.975-0.96(524.88)
= 413.975-503.8848
= - 89.9098
a = -89.910
putting these values into the equation, we have:
^y = -89.910 + 0.9600x
which is also
^y = 0.960x - 89.910

Answer:
(p, q) = (16, 20)
Step-by-step explanation:
You can add the two equations together to make one from which q can be eliminated:
(4p) +(3p -q) = (-q +84) +(28)
7p -q = -q +112 . . . . simplify
7p = 112 . . . . . . . . . . add q
p = 112/7 = 16
Using this value in the second equation, we get ...
3·16 -q = 28
48 -28 = q = 20 . . . . . add q-28
The equilibrium point is (p, q) = (16, 20).

You are given space that limit as h rightwards arrow 0 of fraction numerator g (3 + h) - g (3)/h = 7 and g (3) = 9. Find m and b so that the tangent space line of g (x) at x = 3, y = m x +b.
Answers
Answer:
m = 7 and b = -12 therefore y = 7x - 12
Step-by-step explanation:
From the question we are given the first derivative of the function g to be 7, and it is known that the first derivative of a function is the slope, therefore the slope, m = 7.
Since we are looking for 'b' at x = 3 and we know that our slope is 7, we have:
g(3) = 7*3 + b. We are given g(3) = 9 so we have:
9 = 21 + b and b = -12.
Therefore, m = 7 and b = -12 and the equation of the line is y = 7x - 12.

Measures of two anges 48 degrees are shown in a triangle. Write a equation showing the value of X
Answers
Answer:84
Step-by-step explanation:
Since each trinagle's interior angles which is the angles in side the triangle always add up to 180 you could add the 2 given and then subtract by 180 so 48+48 which equals 96 then 180-96 which will give you 84 as x
Answer
48+48+x=180 x=84
Step-by-step explanation:
The sum of the 3 interior angles of a triangle is always the sum of 180 degrees.
In short, this means that all three angles have to equal up to 180 degrees
48+48=96
180-96=84 x=84
To check your answer add
48+48+84 should equal 180. It does

April is going to the bakery to purchase donuts and cinnamon rolls for the office personnel. She must purchase at least 30 items. She has collected only $30, so total cost must be no more than $30. If d represents donuts that cost $0.75 each and r represents cinnamon rolls that cost $1.25 each, which system of inequalities can be used to represent the region for the number of donuts and cinnamon rolls April could purchase?
A.d + r ≥ 30
0.75d + 1.25r ≤ 30
B. d + r ≥ 30
1.25d + 0.75r ≤ 30
C. d + r ≤ 30
0.75d + 1.25r ≥ 30
D. d + r ≤ 30
1.25d + 0.75r ≥ 30
Please answer quickly :)
Answers
The system of inequalities that can be used to represent the region for the number of donuts and cinnamon rolls April could purchase is $0.75d + $1.25r ≤ $30
April cannot spend more than $30. Thus, the inequality sign that would be used is ≤ (the less than or equal to sign).
April wants to purchases two items, cinnamon rolls and donuts. The donuts cost $0.75 per dollar and cinnamon rolls cost $1.25 per dollar.
The total amount April can spend on donuts = $0.75 x d = $0.75d
The total amount April can spend on cinnamon rolls = $1.25 x r = $1.25r
The sum of $0.75d and $1.25r has to be less than $30
This can be represented with this inequality: $0.75d + $1.25r ≤ $30
