Answer:
4/3
Step-by-step explanation:
Out of the six sides 3 are odd and there's 5 numbers greater than 1. Basically these turn to the fractions 3/6 and 5/6 (these fractions stand for the probability they get rolled on this die).
Since the question says OR and not AND you add these fractions!
3/6 + 5/6 = 4/3
Find an equation of the circle that satisfies the given conditions. (Use the variables x and y.)
Center at the origin;
passes through (4, 6)
Answer:
[tex]x^2 + y^2 = 52[/tex]
Step-by-step explanation:
Distance between two points:
Suppose that we have two points, [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]. The distance between them is given by:
[tex]D = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Equation of a circle:
The equation of a circle with center [tex](x_0,y_0)[/tex] and radius r has the following format:
[tex](x - x_0)^2 + (y - y_0)^2 = r^2[/tex]
Center at the origin;
This means that [tex]x_0 = 0, y_0 = 0[/tex]
So
[tex](x - x_0)^2 + (y - y_0)^2 = r^2[/tex]
[tex](x - 0)^2 + (y - 0)^2 = r^2[/tex]
[tex]x^2 + y^2 = r^2[/tex]
Passes through (4, 6)
The radius is the distance from this point to the center. So
[tex]r = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
[tex]r = \sqrt{(4-0)^2+(6-0)^2}[/tex]
[tex]r = \sqrt{16+36}[/tex]
[tex]r = \sqrt{52}[/tex]
So
[tex]r^2 = 52[/tex]
Then
[tex]x^2 + y^2 = r^2[/tex]
[tex]x^2 + y^2 = 52[/tex]

A. an = 1(4)^n-1
B. an = 4(4)^n-1
C. an = 4(1)^n–1
D. an = 1 + (n - 1)4
Answer:
A. an = 1(4)^n-1
Step-by-step explanation:
Geometric sequence:
In a geometric sequence, the quotient between consecutive terms is always the same, called common ratio, and the sequence is given by:
[tex]a_n = a_1(q)^{n-1}[/tex]
In which [tex]a_1[/tex] is the first term and q is the common ratio.
We are given the following sequence:
[tex]a_1 = 1[/tex]
[tex]a_n = 4a_{n-1}[/tex]
So
[tex]a_2 = 4a_1 = 4[/tex]
[tex]a_3 = 4a_2 = 16[/tex]
[tex]a_4 = 4a_3 = 64[/tex]
That is, the quotient between consecutive terms is 4, so [tex]q = 4[/tex].
The first term is already given, [tex]a_1 = 1[/tex]. So
[tex]a_n = a_1(q)^{n-1}[/tex]
[tex]a_n = 1(4)^{n-1}[/tex]
And thus, the correct answer is given by option A.

Find the value of x.
Answer:
B I think because i did my math
Step-by-step explanation:
Write the equation of the line that passes through the points
Y=2x+5
Answer:
Parallel means that the lines never intersect. If the equation of the new line is y=ax+b , then the system
y=ax+b
y=2x+5
needs to have no solutions. Subtracting the equations gives us
(a−2)x+(b−5)=0
In order for this to ever be 0 we need either a≠2 or b=5 , so to stop this from happening, we will require both a=2 and b≠5 .
Since our line now has the form y=2x+b , and (4,5) is on the line, then the equation
5=2⋅4+b
should be true. Since this implies that b=−3 , we have that the parallel line going through (4,5) has equation
y=2x−3

A rectangular bin, completely filled, holds 1,200 cubic feet of grain. If the bin is 6 feet wide and 10 feet long, how deep is it ?
Answer:
20 feet
Step-by-step explanation:
Volume = length x width x height
1200 = 10 x 6 x h
1200 = 60h
h = 1200/60
height = 20
The rectangular bin is 20 feet deep.
What is a cuboid?A cuboid is a three-dimensional shape in which all sides are rectangles. A cuboid has 6 faces, 8 vertices, and 12 edges. All the angles formed at the vertices of a cuboid are right angles. The opposite edges are parallel to each other.
For the given situation,
A rectangular bin is in the shape of a cuboid.
Volume of the rectangular bin,V = 1200 cubic feet
Length of the rectangular bin,l = 10 feet
Width of the rectangular bin,w = 6 feet
Let the height of the rectangular bin be h.
The formula of volume of cuboid is
[tex]V=lwh[/tex]
Now substitute the above values,
⇒ [tex]1200=(10)(6)h[/tex]
⇒ [tex]h=\frac{1200}{60}[/tex]
⇒ [tex]h=20[/tex]
Hence we can conclude that the rectangular bin is 20 feet deep.

Write the equation of a line that is perpendicular to y =(1/2)x - 5 and passes through point (-6,2)
Answer:
y=-2x-10
Step-by-step explanation:
Let us start with a general slope-intercept equation, y=mx+b, where m represents the slope, b represents the y-intercept, and the y and x represents the coordinates the line passes through.
Therefore, the slope of our line
[tex]y=\frac{1}{2}x-5[/tex]
is 0.5
We also know that the perpendicular slope is simply the negative reciprocal of the current slope. We know have:
[tex]-\frac{2}{1} =\\-2[/tex]
Now, let us find the y intercept. We can plug in the x and y values using the given coordinate (–6,2).
[tex]y=-2x+b\\2=-2*(-6)+b\\2=12+b\\b=-10[/tex]
Now, we can write our equation:

About 7% of the population has a particular genetic mutation. 800 people are randomly selected. Find the standard deviation for the number of people with the genetic mutation in such groups of 800.
Answer:
The standard deviation is of 7.22 people.
Step-by-step explanation:
For each person, there are only two possible outcomes. Either they have the mutation, or they do not. The probability of a person having the mutation is independent of any other person, which means that the binomial probability distribution is used to solve this question.
Binomial probability distribution
Probability of exactly x successes on n repeated trials, with p probability.
The expected value of the binomial distribution is:
[tex]E(X) = np[/tex]
The standard deviation of the binomial distribution is:
[tex]\sqrt{V(X)} = \sqrt{np(1-p)}[/tex]
About 7% of the population has a particular genetic mutation.
This means that [tex]p = 0.07[/tex]
800 people are randomly selected.
This means that [tex]n = 800[/tex]
Find the standard deviation for the number of people with the genetic mutation in such groups of 800.
[tex]\sqrt{V(X)} = \sqrt{np(1-p)} = \sqrt{800*0.07*0.93} = 7.22[/tex]
The standard deviation is of 7.22 people.

The experimental probability of rolling a multiple of 3 will be 33%.
What is probability?Its basic premise is that something will almost certainly happen. The percentage of favorable events to the total number of occurrences.
A pair of dice was rolled many times and the results appear below. Based upon these results.
Outcome 2 3 4 5 6 7 8 9 10 11 12
Frequency 3 6 8 11 14 16 15 12 9 5 1
Then the experimental probability of rolling a multiple of 3 will be
Favorable events = 6 + 14 + 12 + 1 = 33
Total events = 100
Then the probability will be
P = (33 / 100) x 100
P = 0.33 x 100

Help me please I’m down baddddd
Answer:
a. m<B = 100°
b. m<L = 55°
c. Scale factor = 9/11
Step-by-step explanation:
a) Similar triangles have their three corresponding angles congruent to each other, while the ratio of their corresponding sides are proportional to each other.
Since ∆ABC ~ ∆GLJ, therefore,
<A = <G,
<B = <J
<C = <L
m<J = 100° (given)
Therefore,
m<B = m<J = 100°
m<B = 100°
b) m<A = m<G
m<A = 25° (given)
Therefore,
m<A = m<G = 25°
m<G = 25°
m<L = 180° - (m<J + m<G)
Substitute
m<L = 180° - (100° + 25°)
m<L = 55°
c) scale factor of smaller triangle to the larger = side length of smaller triangle / corresponding side length of bigger triangle
Scale factor = AB/GJ
Substitute
Scale factor = 18/22
Simplify
Scale factor = 9/11

Find a formula for the described function. An open rectangular box with volume 3 m3 has a square base. Express the surface area SA of the box as a function of the length of a side of the base, x.
Answer:
[tex]SA(x) = x^2 + \frac{12}{x}[/tex]
Step-by-step explanation:
Given
[tex]V = 3m^3[/tex] --- volume
[tex]x \to base\ length[/tex]
[tex]y \to height[/tex]
Required
The surface area as a function of base length
The volume (V) is calculated as:
[tex]V = Base\ Area * Height[/tex]
[tex]V = x*x*y[/tex]
[tex]V = x^2*y[/tex]
Make y the subject
[tex]y = \frac{V}{x^2}[/tex]
Substitute 3 for V
[tex]y = \frac{3}{x^2}[/tex]
The surface area of the open box is:
[tex]SA = x^2 + 2xy+2xy[/tex]
[tex]SA = x^2 + 4xy[/tex]
Substitute: [tex]y = \frac{3}{x^2}[/tex]
[tex]SA = x^2 + 4x*\frac{3}{x^2}[/tex]
[tex]SA = x^2 + 4*\frac{3}{x}[/tex]
[tex]SA = x^2 + \frac{12}{x}[/tex]
Hence, the function is:
[tex]SA(x) = x^2 + \frac{12}{x}[/tex]

Find your answer by using the formula of a cone (v= [tex]\frac{1}{3}[/tex]π[tex]r^{2}[/tex]h)
r= 2 (half of your diameter, which is 4)
h= 4
