Write an equation in slope-intercept form of the line that passes through the given points.
Answer:
y = 1/2x+1
Step-by-step explanation:
Slope = Δy/Δx
The difference is y increases by 1 and difference in x increases by 2. So the slope is 1/2.
Slope-intercept form: y=mx+b
We take point (0,1) and input into this equation.
1= 1/2×0 +b
1 = b

The time between arrivals of small aircraft at a county airport is exponentially distributed with a mean of one hour. (a) What is the probability that more than three aircraft arrive within an hour? (b) If 30 separate one-hour intervals are chosen, what is the probability that no interval contains more than three arrivals?(c) Determine the length of an interval of time (in hours) such that the probability that no arrivals occur during the interval is 0.10.
Answer:
(a) The probability that more than three arrive in one hour is approximately 0.018988
(b) The probability that no interval contains more than 3 arrivals in 30 separate one-hour intervals is approximately 0.56264
(c) The length of time such that the probability of no arrival is 0.1 is approximately 2.30259 hours
Step-by-step explanation:
The distribution of the arrival time of a small aircraft = Exponential distribution
The mean arrival time, μ = 1 hour
The pdf of a exponential distribution, f(x) = λ·e^(-λ·x)
The mean, μ = 1/λ
∴ 1 = 1/λ
λ = 1 hour
∴ For the exponential distribution, f(x) = 1·e^(-x)
(a) The Poisson probability is given as follows;
[tex]P(X = k) = \dfrac{\lambda^k \times e^{-k}}{k!}[/tex]
The probability for more than 3 is given as follows;
[tex]P(X > 3) = 1 - \dfrac{1^0 \times e^{-1}}{0!} - \dfrac{1^1 \times e^{-1}}{1!} - \dfrac{1^2 \times e^{-1}}{2!} - \dfrac{1^3 \times e^{-1}}{3!} \approx 0.018988[/tex]
(b) P(X ≤ 3) for 30 1 hour intervals = P(X ≤ 3)³⁰ = (1 - 0.018988)³⁰ ≈ 0.56264
(c) When the probability that no arrival occurs is 0.1, we have;
0.1 P(X > x) = f(x) = 1·e^(-x) = e^(-x)
-x·ln(e) = ln(0.1)
∴ x = -㏑(0.1) ≈ 2.30259
The length of time such that the probability that no arrival occur during the interval is 0.1, x ≈ 2.30259 hours.

GUYS PLEASE HELP!!A gardener plans to construct a triangular garden using logs for the edges. She has logs that measure
5 meters and 3 meters. Which of the following lengths could be used for the third side of the garden?
A 2 meters
B 6meters
C 8meters
D 9meters
Answer:
6 meters
Step-by-step explanation:
The sum of the lengths of any two sides of a triangle is always greater than the length of the third side. And this MUST be true for all the combinations
The only length where this is true is 6
3+5 is greater than 6
2+6 is greater than 5
5+6 is greater than 3

The number of subjects studied for the exam is 3 subjects
What is a fraction?A fraction is written in the form of a numerator and a denominator where the denominator is greater than the numerator.
Example: 1/2, 1/3 is a fraction.
We have,
On Saturday:
The number of hours Kiana studied = 2 ¼ hours
This can be written as,
= 2 (1/4)
= 9/4 hours _____(A)
The number of hours studied for each subject.
= ¾ hour ______(B)
The formula for dividing fractions.
= a/b ÷ c/d
= ad/bc
Now,
From (A) and (B) we get,
The number of subjects.
= 9/4 ÷ 3/4
= (9 x 4) / (4 x 3)
= 3 subjects
Thus,
The number of subjects studied for the exam is 3 subjects

Which ordered pair describes a point that is located 4 units to the left of the origin and 2 units below the x-axis?
Answer:
(-4,2)
Step-by-step explanation:
The coordinates in a graph indicate the location of a point with respect to the x-axis and y-axis.
The ordered pair that describes a point that is located 4 units to the left of the origin and 2 units below the x-axis is (-4, -2)
What are coordinates in a graph?The coordinates in a graph indicate the location of a point with respect to the x-axis and y-axis.
The coordinates in a graph show the relationship between the information plotted on the given x-axis and y-axis.
We have,
The point is located 4 units to the left of the origin and 2 units below the
x-axis.
4 units to the left of the origin.
This means,
x = -4
2 units below the x-axis.
This means,
y = -2
The coordinate in the form of ordered pair is (-4, -2).
Thus,
The ordered pair that describes a point that is located 4 units to the left of the origin and 2 units below the x-axis is (-4, -2)

Answer:
cosA = 8/17
Step-by-step explanation:
cos = adjacent/hypotenuse
The number that is adjacent to angle A is 24 and the hypotenuse is 51
Plug the numbers into the cosine equation, which would look like:
Cos A = 24/51

At what point(s) do these graphs intersect? y=x^2 = 3x-5
y=4x+1
Seth’s solution:
y=x^2 +3x-5
y=4x+1
x^2 =3x-5=4x+1
x^2 -x-6=0
(x-3)(x+2)=0
x=3 and x=-2
The graphs intersect at (-2,0) and (3,0).
Is Seth's solution correct? Explain.
Answer:
Solution is correct till finding the roots:
x = 3, x = -2Then Seth should find the respective y- points using either equation:
y = 4*3 + 1 = 13and
y = -2*4 + 1 = -7Correct solution is:
(3, 13) and (-2, -7)Answer:
Seth's answer is incorrect.
Step-by-step explanation:
He is correct with all of his steps until he reaches the roots... the correct roots are, y = 4(3) + 1 = 13 y = 4(-2) + 1 = -7
So the correct answer would actually be: The graphs intersect at the coordinates (3,13) and (-2,-7)
A trapezoid has a height of 3 meters, a base length of 8 meters, and an area of 30 square meters. What is the length of the base?
Answer:
Length of the second base will be 12 meters.
Step-by-step explanation:
Area of a trapezoid is given by the formula,
Area = [tex]\frac{1}{2}(b_1+b_2)h[/tex]
Here, b₁ and b₂ are the bases of the trapezoid and 'h' is the vertical distance between the bases.
By substituting the values in the formula,
[tex]30=\frac{1}{2}(8+b_2)3[/tex]
[tex]60=3(8+b_2)[/tex]
[tex]20=8+b_2[/tex]
[tex]b_2=12[/tex]
Therefore, length of the second base will be 12 meters.

Answer:
A. the area of the large pond is 16 times the area of the small pond
Step-by-step explanation:
let's say 4 is the radius of the small circle, which means the area is 50.26548
if the large circle is 4 times the small circle, that means it's radius is 16 which means the area is 804.24772
so if you divide the big circle area by the small circle area:
804.24772/50.26548
it gives you 16.00000079577 which is rounded to 16
therefore, the bigger circle is 16 times bigger than the smaller circle
