A farmer wants to know the effect of using various amounts of fertilizer in relation to the yield of his crops. He subdivided a portion of his land into 10 separate, but essentially equal, plots. He divided the land so that all of the plots had equal exposure to sun, rain, and other environmental conditions. He randomly selected 2 of the 10 plots and spread 2 pounds of fertilizer over each of them. Then he randomly selected 2 of the remaining plots and spread 3 pounds of fertilizer over each of them. He continued with the last sets of plots in the same manner, spreading 4, then 5, then 6 pounds of fertilizer over each of them. Assume the conditions for regression inference have been satisfied. To construct the 90% confidence interval for the true slope of the population regression equation relating amount of fertilizer to yield.
Required:
How many degrees of freedom does the t-distribution have?
Answer:
Option b is correct answer
Step-by-step explanation:
The complete question is attached herewith
Solution
The equation of a line in given by
y=a +bx where
a is the Y- intercept and
b is the slope
From the given piece of information, we can derive that
coefficient of intercept = 10.1
coefficient of fertilizer= 1.150
Substituting the given values in above equation, we get -
y=10.1+1.150x
Option b is correct answer
Quadrilateral ABCD is inscribed in a circle. Angle B measures 74 degrees,and angle D measures (x-15) degrees.What does x equal?
A-106
B-105
C-91
D-121
pls help asap
Answer:
121degrees
Step-by-step explanation:
For a quadilateral inscribed in a circle, the sum of its opposite angles is 180degrees. Hence;
<B + <D = 180
x -15 + 74 = 180
x + 59 = 180
x = 180 - 59
x = 121 dgrees
Hence the value of x is 121degrees
2x3 + 10x2 − 4x2y − 20xy Part A: Rewrite the expression by factoring out the greatest common factor. (4 points) Part B: Factor the entire expression completely. Show the steps of your work. (6 points)
Answer:
[tex]2x(x-2y)(x+5)[/tex]
Step-by-step explanation:
Factor out any GCFs before proceeding!
[tex]2x(x^2+5x-2xy-10y)[/tex]
Split the parenthesis into two.
[tex]2x((x^2+5x)-(2xy-10y))[/tex]
Factor out GCFS of both again!
[tex]2x(x(x+5)-2y(x-5))[/tex]
Now that you have two matching equations, you can cancel one out!
[tex]2x(x-2y)(x+5)[/tex]

In the first quadrant ,you start at 4,6 and move 3 units right and 1 unit down ,what point will u end up
Answer:
You end up at point (7,5).
Step-by-step explanation:
Starting point:
The coordinates of the starting point are: x = 4, y = 6.
So
(4,6).
Move 3 units right:
Moving 3 units right is adding 3 to the x-coordinate. So
x = 4 + 3 = 7
(7,6).
Move 1 unit down:
Moving 1 unit down is subtracting 2 from the y-coordinate. So
y = 6 - 1 = 5.
You end up at point (7,5).
In circle A below, points B, C, and D lie on the circle, and mZBDC = 35".
Answer:
arcBC = 140degrees
Step-by-step explanation:
From the given digaram;
Angle at the center is twice angle at the circumference
Hence;
m<CAB = 2(m<CDB)
m<CAB = 2 * 35
m<CAB = 70degrees
Also;
m<CAB = 1/2 arcBC
70 = 1/2arcBC
arcBC = 70*2
arcBC = 140degrees

Find the measure of the exterior angle.
Step-by-step explanation:
exterior angle
-> (4x + 6)° = x + 102°
3x = 102° - 6°
3x = 96°
x = 32°
4x + 6°= 4×32° + 6° = 128 + 6 = 134°

in new england 47% of the houses have a garage and 36% of the houses have a garage and a backyard what is the probability that a house has a backyard given that has a garage probs and stats
Answer:
The probability that a house has a backyard given that has a garage is 76.60%.
Step-by-step explanation:
Given that in New England 47% of the houses have a garage and 36% of the houses have a garage and a backyard, to determine what is the probability that a house has a backyard given that has a garage the following crossed multiplication must be performed:
47 = 100
36 = X
(36 x 100) / 47 = X
3,600 / 47 = X
76.5957 = X
Therefore, the probability that a house has a backyard given that has a garage is 76.60%.

Sue’s height is 3 inches less than Ed’s height. Ed is 56 inches tall. How tall is Sue? Write an equation to represent the situation. Then solve the equation to answer the question.
Answer:
S = E - 3
Sue is 53 inches tall.
Step-by-step explanation:
Let Sue's age be represented by S and Ed's by E
Equation:
S = E - 3
E = 56 inches
S = 56 - 3 = 53 inches

In ΔXYZ, ∠Y=90° and ∠X=73°. ∠ZWY=80° and XW=80. Find the length of ZY to the nearest 100th.
Answer:
Solution given:
Y=90°
∠X=73°.
∠ZWY=80°
and XW=80.
ZY=?
We know that
In right angled triangle ∆ XYZ
Tan 73=[tex] \frac{p}{h} [/tex]
3.27=[tex] \frac{yz}{xy} [/tex]
3.27×[xy]=yz
xw+wy=[tex] \frac{yz}{3.27} [/tex]
wy=[tex] \frac{yz}{3.27} [/tex]-80...........(1)
again
In right angled triangle WYZ
Tan 80=[tex] \frac{yz}{wy} [/tex]
5.67×wy=yz
wy=[tex] \frac{yz}{5.67} [/tex]
yz=5.67×wy............................................(2)
Equating equation 1&2
[tex] \frac{yz}{5.67} [/tex]=[tex] \frac{yz}{3.27} [/tex]-80
[tex] \frac{yz}{3.27} [/tex]-[tex] \frac{yz}{5.67} [/tex]=80
5.67yz-3.27yz=80*5.67*3.27
2.4yz =1483.272
yz=[tex] \frac{1483.272}{2.4} [/tex]
yz=618.03
:.y=618.03unit.the length of ZY to the nearest 100th is 618.
