A total of 2 feet of snow falls over three days. On the first day, 1/6 of the total snow falls. On the second day, 7/12 of the total snow falls.
On third day 1/2 of the total snow falls.
What is the fraction?In Mathematics, fractions are represented as a numerical value, which defines a part of a whole. A fraction can be a portion or section of any quantity out of a whole, where the whole can be any number, a specific value, or a thing.
Given that, total of 2 feet of snow falls over three days.
On the first day, 1/6 of the total snow falls. On the second day, 7/12 of the total snow falls.
So, the snow fall on third day will be
= 2(1-1/6-7/12)
= 2((12-2-7)/12)
= 2(3/12)
= 2(1/4)
= 1/2
Therefore, on third day 1/2 of the total snow falls.

If a figure is reflected over the x-axis and then reflected over the y-axis, what one transformation would accomplish the same end resulting figure?
Answer:
rotation
by rotating the figure clockwise 180 degrees you would get the same thing as reflected it over the x and then the y axis
In most cases; when an object is transformed, the orientation and layout of the object changes. The one transformation that will accomplish this is 180 degrees rotation.
Let the point on the figure be (x,y)
When reflected over the x-axis, the transformation rule is:
[tex](x,y) \to (x,-y)[/tex]
When reflected over the y-axis, the transformation rule is:
[tex](x,y) \to (-x,y)[/tex]
This means that:
[tex](x,-y) \to (-x,-y)[/tex]
So, the reflection is:
[tex](x,y) \to (x,-y) \to (-x,-y)[/tex]
The single transformation that can achieve this is: rotation by 180 degrees.
The rule of transformation is:
[tex](x,y) \to (-x,-y)[/tex]
Hence, one transformation that would accomplish the reflections is: 180 degrees rotation.

Step-by-step explanation:
Imagine a population of birds with an initial size of 100, a per-capita birth rate of 2, and a per-capita death rate of 1 per year. Use the discrete time form of the exponential growth equation to predict the number of individuals in this population after 5 years of growth.
Answer:
3200
Step-by-step explanation:
Given that:
The initial population of birds [tex]N_0[/tex] = 100
The time duration t = 5 years
Growth rate (r) = (Birth - Death) rate
= 2 - 1
= 1 / year
∴
using the discrete-time form:
[tex]N_t = N_o (1 + r )^t[/tex]
[tex]N_t = 100 (1 + 1 )^5[/tex]
[tex]N_t = 100 (2 )^5[/tex]
[tex]N_t = 100 \times 32[/tex]
[tex]N_t = 3200[/tex]
Assume the population has a normal distribution. A sample of 25 randomly selected students Has a mean test score of 81.5 With a standard deviation of 10.2. Construct a 90% confidence interval for the mean test score.
Answer:
The 90% confidence interval for the mean test score is between 77.29 and 85.71.
Step-by-step explanation:
We have the standard deviation for the sample, so we use the t-distribution to solve this question.
The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So
df = 25 - 1 = 24
90% confidence interval
Now, we have to find a value of T, which is found looking at the t table, with 24 degrees of freedom(y-axis) and a confidence level of [tex]1 - \frac{1 - 0.9}{2} = 0.95[/tex]. So we have T = 2.064
The margin of error is:
[tex]M = T\frac{s}{\sqrt{n}} = 2.064\frac{10.2}{\sqrt{25}} = 4.21[/tex]
In which s is the standard deviation of the sample and n is the size of the sample.
The lower end of the interval is the sample mean subtracted by M. So it is 81.5 - 4.21 = 77.29
The upper end of the interval is the sample mean added to M. So it is 81.5 + 4.21 = 85.71.
The 90% confidence interval for the mean test score is between 77.29 and 85.71.

What is Right Angle?Right angles are the angles formed by two rays which is equal to 90 degrees.
Given a triangle KLJ.
A perpendicular line is drawn from the vertex K to it's opposite side LJ at a point M, which in turn forms a right angled triangle KMJ.
For right angled triangle, we have a theorem named Pythagoras Theorem which states that,
Hypotenuse² = Base² + Altitude²
Here base is the line segment MJ and altitude is KM and the hypotenuse is the line segment KJ
Length of base = 3 units
Length of altitude = 6 units
By Pythagoras theorem,
Hypotenuse² = Base² + Altitude²
= 3² + 6²
= 9 + 36
= 45
Hypotenuse = [tex]\sqrt{45}[/tex]
= √(9 × 5)
= √9 × √5
= 3√5
Hence the length of the line segment KJ is 3√5 units.

Answer:
Equation of line passing through points is: [tex]y=\frac{7}{2}x-6[/tex]
Step-by-step explanation:
Given points are;
(-4, -20) and (12, 36)
First we will find slope of the equation,
m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]m = \frac{36-(-20)}{12-(-4)}\\\\m = \frac{36+20}{12+4}\\\\m = \frac{56}{16}\\\\m = \frac{7}{2}[/tex]
Equation of a line is given by;
y = mx + b
Putting (-4, -20) in this equation to find b.
[tex]-20=\frac{7}{2}*-4+b\\-20 = -14 + b \\-20+14 = b \\b = -6[/tex]
The equation is;
[tex]y = \frac{7}{2}x - 6[/tex]
Hence,
Equation of line passing through points is: [tex]y=\frac{7}{2}x-6[/tex]

What is a circle?
A circle is a two-dimensional figure with a radius and circumference of
2πr.
The area of a circle is given as πr²
r is the radius of the circle.
Example:
The area of a circle with a radius of 2 cm is 4π cm².
We have,
The radius of the circle = 40 cm.
The area of the circle = πr²
Now,
Area of the circle.
= π x 40²
= π x 40 x 40
[ π = 3.14 ]
= 3.14 x 40 x 40
= 5024 cm²
We see that,
5024 cm² is closest to 5026 cm².
Thus,
The area closest to 5024 cm² is 5026 cm².
Option B is the correct answer.
