Jalen says that the height, radius, and diameter of a cone lie entirely on the base of the cone. What is Jalen’s error?
The height does not lie on the base because it is perpendicular to the base.
The radius does not lie on the base because it contains the center of the base.
The diameter does not lie on the base because it contains a radius of the circle.
The base does not contain the height, the radius, or the diameter because it is a circle.
Answer:
A, or "The height does not lie on the base because it's perpendicular to the base."
Step-by-step explanation:
EDGE 2021
Option A is correct, the height does not lie on the base because it is perpendicular to the base.
What is Three dimensional shape?a three dimensional shape can be defined as a solid figure or an object or shape that has three dimensions—length, width, and height.
Given that Jalen says that the height, radius, and diameter of a cone lie entirely on the base of the cone.
We have to find the Jalen’s error.
As we know that height does not lies on the base because it is perpendicular to the base.
The Jalens error is that height does not lie on the base because it is perpendicular to the base is a error statement.
Hence, option A is correct, the height does not lie on the base because it is perpendicular to the base.

Step-by-step explanation:
Part (a)f(x - 1) is the translation of f(x) one unit right.
So the graph is exactly same shape but shifted right one unit.
Part (b)f(x) has vertex (-1, 2)
The function y = f(-x) + 2 will have the vertex changed as per rule:
(x, y) → (-x, y + 2)So the new vertex is:
(-1, 2) → (-(-1), 2 + 2) = (1, 4)Help:( me please I don’t know what to do I completely for got it

According to the graph, what is the factorization of x2 - 6x + 5?
A. (x + 5)(x+1)
B. (x - 5)(x+ 1)
C. (x - 5)(x - 1)
D. (x + 5)(x - 1)
The factorization of x2 - 6x + 5 is (x - 1)(x -5)
How to determine the factorization?From the graph, the zeros of the function are:
x = 1 and x = 5
Set the zeros to 0
x - 1 = 0 and x - 5 = 0
Multiply the zeros
(x - 1)(x -5) = 0
Hence, the factorization of x2 - 6x + 5 is (x - 1)(x -5)

2. You are standing 15 feet from a tree. You want to get an apple from the tree using a ladder that is 25 feet long. What is the height of the tree? What is the angle of elevation?
Answer:
h = 20 ft
theta =53.13010235
Step-by-step explanation:
First we can find the height by the Pythagorean theorem
a^2 + b^2 = c^2 where a and b are the legs
15^2 + h^2 = 25^2
225 + h^2 = 625
h^2 = 625 - 225
h^2 = 400
Taking the square root of each side
h = 20 ft
Now using trig functions
cos theta = adj side / hyp
cos theta = 15/25
Taking the inverse cos of each side
cos^-1 ( cos theta) = cos^-1 ( 15/25)
theta =53.13010235

Suppose that 3 balls will be randomly put into 3 buckets, with each ball being equally likely to be put into each of the buckets, independently of which buckets are chosen for any of the other balls. (E.g., the first ball is equally likely to be put into any of the 3 buckets, and then regardless of which bucket the first ball is placed in, the second ball is equally likely to be put into any of the 3 buckets.) What is the probability that all of the balls will be put into the same bucket
Answer:
[tex]\frac{1}{27}[/tex]
Step-by-step explanation:
Since there are a total of three buckets and only one can be chosen at a time, this would mean that the probability of a ball being placed in a bucket is 1/3. Since each ball has the same probability of being placed into any bucket regardless of the where the previous ball landed, it means that each ball has the same 1/3 probability of a bucket. In order to find the probability that all three land in the same bucket, we need to multiply this probability together for each one of the balls like so...
[tex]\frac{1}{3} * \frac{1}{3} * \frac{1}{3} = \frac{1}{27}[/tex]
Finally, we see that the probability of all three balls landing in the same bucket is [tex]\frac{1}{27}[/tex]

The formula for X's cumulative distribution function (CDF) is
a. Probability P(X≤3) = P(X=1) + P(X=2) + P(X=3) = 1/7 + 1/14 + 3/14 = 5/14
b. P(X<3) = P(X=1) + P(X=2) = 1/7 + 1/14 = 3/14
c. P(X<4.12|X>1.638) = P(2<X<4.12)/P(X>1.638) = [P(X=3)+P(X=4)]/[1-P(X=1)] = (3/14)/(11/14) = 3/11
d. The cumulative distribution function of X, for x = 5, F(5) = 1
What is probability?Probability can be defined as the ratio of the number of favorable outcomes to the total number of outcomes of an event.
Here, we have,
a. Probability P(X≤3) = P(X=1) + P(X=2) + P(X=3) = 1/7 + 1/14 + 3/14 = 5/14
b. P(X<3) = P(X=1) + P(X=2) = 1/7 + 1/14 = 3/14
c. P(X<4.12|X>1.638) = P(2<X<4.12)/P(X>1.638) = [P(X=3)+P(X=4)]/[1-P(X=1)] = (3/14)/(11/14) = 3/11
d. The formula for X's cumulative distribution function (CDF) is
F(x) = P(X < x)
For x = 1, F(1) = 1/7
For x = 2, F(2) = 1/7 + 1/14 = 3/14
For x = 3, F(3) = 1/7 + 1/14 + 3/14 = 5/14
For x = 4, F(4) = 1/7 + 1/14 + 3/14 + 2/7 = 11/14
For x = 5, F(5) = 1
As a result, X's CDF is:
F(x) = {1/7, x < 1
3/14, 1 ≤ x < 2
5/14, 2 ≤ x < 3
11/14, 3 ≤ x < 4
1, x ≥ 4}

Step-by-step explanation:
Looking at the right triangle we see two congruent sides, which means that we can find the angles:
180 - 64 = 116° for both bottom angles of the right triangle, so 58° (116°/2).
Looking at the middle angle we know that left corner from the left triangle is 58° so the angle in the middle would be 180 - 58 = 122°.
Since the right triangle equals to 180° then we can find the missing values including x:
180 - 122 = 58° is the total angle for each corner of the right triangle. So x would be 58/ 2 = 29°.
Therefore x = 29°.

Select the best answer to complete the sentence. A Rigid Motion or Isometry ______________________.
A. preserves length, angle measures and distance between points
B. preserves length and angle measures but not distance between points
C. is a transformation that changes the size of the figure
is a transformation with its image and pre-image not being congruent
Answer: A. preserves length, angle measures and distance between points
Rigid motions or isometries are any of the three transformations below
translation (aka shifting)rotationreflectionAny of those three transformations will keep the figure the same size and shape. That means distances between any two points are kept the same, and angle measures are kept the same as well. Everything is kept the same. The only difference is that the figure is in a different location, is rotated somehow, or it is reflected some way. You can use a series of transformations to undo everything to get the original figure back.
If you wanted to change the size of the figure, then you would apply dilation, which isn't an isometry.
