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°

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
What is the tenth term of the sequence described by the rule?
A(n)=−9+5(n−1)
Answer:
46
Step-by-step explanation:
Replace n by 10 in the rule a(n) = -9 + 5(n - 1):
a(10) = -9 + 5(9) = 45 - 9 = 46

Step-by-step explanation:
By the Triangle Midsegment Theorem, the midsegment connecting the midpoints of two sides of a triangle is parallel to the third side of the triangle, and the length of this midsegment is half the length of the third side. Therefore, (1/2)FH ≡ IH, (1/2)HG ≡ HJ. Knowing that IJ = 8 gives you the presidence to solve for the perimeter.
PLEASEEE HELP ME FIND THE SURFACE AREA
Will mark brainliest!!
Answer:
100.48
Step-by-step explanation:
Surface area of a cylinder = [tex]2\pi r^2+2\pi rh[/tex]
Where r = radius and h = height
We are given the diameter ( 4 cm ) and the height ( 6cm )
To convert diameter to radius we simply divide by 2 ( because radius = half the length of the diameter )
4 / 2 = 2 Thus, r = 2
Now we plug in the values of the radius and height into the surface area of a cylinder formula ( note we must use 3.14 for π as the question says to. not doing so can result in a wrong answer )
[tex]SA=2(3.14)(2^2)+2(3.14)(2)(6)\\2^2=4\\4*3.14=12.56\\12.56*2=25.12\\\\2*3.14=6.28\\6.28*2=12.56\\12.56*6=75.36\\\\75.36+25.12=100.48\\SA=100.48cm^2[/tex]
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 question 4 you have to cross multiply
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
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%.
