Answer:
B) 12
Step-by-step explanation:
(9y + 7)° + (7y - 19)° = 180° (interior angles in the same side of transversal)
(9y + 7 + 7y - 19)° = 180°
(16y - 12)° = 180°
16y - 12 = 180
16y = 180 + 12
16y = 192
y = 192/16

In analyzing hits by certain bombs in a war, an area was partitioned into 561 regions, each with an area of 0.75 km2. A total of 525 bombs hit the combined area of 561 regions. Assume that we want to find the probability that a randomly selected region had exactly four hits. In applying the Poisson probability distribution formula, P(x)=
μx•e−μ
x!, identify the values of μ, x, and e. Also, briefly describe what each of those symbols represents.
Answer:
x is the number of successes
e = 2.71828 is the Euler number
\(\mu\) is the mean in the given interval.
There is a 17.18% probability that a randomly selected region had exactly two hits.
Step-by-step explanation:
In a Poisson distribution, the probability that X represents the number of successes of a random variable is given by the following formula:
\(P(X=x)=\dfrac{e^{-\mu}\times\mu^x}{(x)!}\)
In which
x is the number of successes
e = 2.71828 is the Euler number
\(\mu\) is the mean in the given interval.
In this problem we have that:
A total of 525 bombs hit the combined area of 561 regions. So the mean hits per region is:
\(P=\dfrac{525}{561}=0.9358\)
Assume that we want to find the probability that a randomly selected region had exactly two hits.
This is P(X = 2).
\(P(X=x)=\dfrac{e^{-\mu}\times\mu^x}{(x)!}\)
\(P(X=2)=\dfrac{e^{-0.9358}\times(0.9358)^2}{(2)!}=0.1718\)
There is a 17.18% probability that a randomly selected region had exactly two hits.

What are the coordinates of the midpoint of the line segment AB?Midpoint, as the word suggests, means the point which lies in the middle of something. The midpoint of a line segment means a point that lies in the mid of the given line segment.
Suppose we've two endpoints of a line segment:
A(p,q), and B(m,n)
Then let the midpoint be M(x,y) on that line segment. Then, its coordinates are:
\(x = \dfrac{p+m}{2}\)
and
\(y = \dfrac{q+n}{2}\)
Given the two endpoint coordinates of the line AB, which are A(-4,2) and B(1,-4). Therefore, the coordinates of the midpoint of the line are:
\(x = \dfrac{-4+1}{2} =-\dfrac{3}{2}\)

(1 point) find the solution to the differential equation dydx y2=0, subject to the initial conditions y(0)=10. y=
The solution to the differential equation dy/dx y^2 = 0, subject to the initial condition y(0) = 10 is y(x) = 10.
The solution to the differential equation dy/dx y^2 = 0, subject to the initial condition y(0) = 10 is:
y(x) = 10
To solve the given differential equation, we can first separate the variables by dividing both sides by y^2 to get:
1/y^2 dy/dx = 0
We can then integrate both sides with respect to x to obtain:
-1/y = C
where C is the constant of integration. Solving for y, we get:
y = -1/C
Since we have an initial condition of y(0) = 10, we can substitute this into the solution to solve for C:
10 = -1/C
C = -1/10
Substituting C back into the solution, we get:
y = -10
Therefore, the solution to the differential equation dy/dx y^2 = 0, subject to the initial condition y(0) = 10 is y(x) = 10.

A jug of orange juice contains 250cm^3 of juice. If a glass has a radius of 2cm and is 3cm tall . How many glasses can a jug of orange juice fill?
a jug of orange juice containing 250 cm^3 of juice can fill 6 glasses with a radius of 2cm and a height of 3 cm each.
To solve this problem, we need to find the volume of each glass of orange juice and then divide the total volume of the jug by the volume of one glass to get the number of glasses that can be filled.
The volume of a glass can be calculated using the formula for the volume of a cylinder, which is:
V = πr^2h
where V is the volume, r is the radius, and h is the height.
Substituting the values given in the problem, we get:
V = π(2cm)^2(3cm) = 12π cm^3
Therefore, the volume of one glass is 12π cm^3.
To find the number of glasses that can be filled with a jug of orange juice that contains 250 cm^3 of juice, we can divide the total volume of the jug by the volume of one glass:
Number of glasses = Total volume of jug / Volume of one glass
Number of glasses = 250 cm^3 / 12π cm^3
Number of glasses ≈ 6.57
Since you can't have a fraction of a glass, we need to round down to the nearest whole number. Therefore, a jug of orange juice can fill 6 glasses.
So, to summarise, a jug of orange juice containing 250 cm^3 of juice can fill 6 glasses with a radius of 2cm and a height of 3 cm each.

The values will be graphed on the following grid.
An empty grid graph with the number of days taken on the x-axis, and the number of raincoats manufactured taken on the y-axis.
Which is the most appropriate choice of origin and scale for this graph?
A.
x-axis scale: 1 unit = 1 day
y-axis scale: 1 unit = 100 raincoats
origin: (0 days, 100 raincoats)
B.
x-axis scale: 1 unit = 3 days
y-axis scale: 1 unit = 100 raincoats
origin: (5 days, 0 raincoats)
C.
x-axis scale: 1 unit = 3 days
y-axis scale: 1 unit = 25 raincoats
origin: (0 days, 0 raincoats)
D.
x-axis scale: 1 unit = 1 day
y-axis scale: 1 unit = 25 raincoats
origin: (5 days, 200 raincoats)
For given dataset, Option A is the best choice of origin and scale for the graph.
What exactly is a data set?
A dataset is a collection of data that is organized and stored in a specific way for easy analysis and interpretation. It can be thought of as a set of observations or measurements collected for a specific purpose or study. A dataset can contain various types of data, such as numerical, categorical, or text data, and can be organized in different formats, such as spreadsheets, tables, or databases. Data sets are used in various fields, including statistics, machine learning, and data analysis, to derive insights and make informed decisions.
Now,
A is the most appropriate choice of origin and scale for this graph.
The x-axis represents the number of days, which is a discrete variable that is usually measured in whole units, so it makes sense to have a scale of 1 unit = 1 day.
The y-axis represents the number of raincoats, which is a continuous variable that ranges from 200 to 375 in this case. A scale of 1 unit = 100 raincoats would allow us to show the range of data without having a very large graph.
The origin is placed at (0 days, 100 raincoats) so that the entire range of data can be shown on the graph, without any data points being cut off.

when we divide the number of seconds in december by the number of seconds in november, we get a remainder of $r$. if we then divide $r$ by $11$, what remainder do we get?
The remainder when r is divided by 11 is 6.
Remainder is the amount left after dividing a number by another. After dividing a number with another, it will result to an integer and a remainder, which is less than the divisor.
Divide the number of seconds in December by the number of seconds in November and get the remainder, r.
number of seconds in December ÷ number of seconds in November
31days(24h/day)(60min/h)(60s/min) ÷ 30days(24h/day)(60min/h)(60s/min)

Is 10 12 15 a Pythagorean triple?
No, 10 12 15 is not a Pythagorean triple. A Pythagorean triple is a set of three positive integers a, b, and c such that a^2 + b^2 = c^2.
To determine whether 10 12 15 is a Pythagorean triple, we need to calculate a^2 + b^2.
In this case, 10^2 + 12^2 = 100 + 144 = 244. Since 244 ≠ 15^2, 10 12 15 is not a Pythagorean triple. We can also confirm this by plugging 10, 12, and 15 into the Pythagorean Theorem, a^2 + b^2 = c^2.
10^2 + 12^2 = 100 + 144 = 244
244 ≠ 15^2

Find the exact acute angle \( \theta \) for the given function value. \[ \cos \theta=\frac{1}{2} \] \[ \theta=60+360 n, 300+360 n \]
The exact acute angle for the given function value is 60 degrees.
We are given that the cosine of an angle, denoted as θ, is equal to 1/2.
By inspecting the unit circle or referring to the trigonometric ratios, we find that the cosine of 60 degrees is 1/2.
Therefore, the exact acute angle θ that satisfies the equation cos θ = 1/2 is 60 degrees.
In trigonometry, the cosine function represents the ratio of the adjacent side to the hypotenuse in a right-angled triangle. When the cosine value is 1/2, it means that the adjacent side is half the length of the hypotenuse. By referring to the unit circle or the values of trigonometric ratios, we can determine that the acute angle with a cosine of 1/2 is 60 degrees.
It's worth noting that trigonometric functions have periodicity, meaning they repeat their values after a certain interval. In this case, the cosine function has a period of 360 degrees, so we can express additional angles that satisfy the equation cos θ = 1/2 using the formulas θ = 60 + 360n or θ = 300 + 360n, where n is an integer representing the number of full rotations.
