Answer:

105.12

Step-by-step explanation:

Find the area of the rectangle (8 x 10 = 80)

Find the area of the whole circle (3.14 x 4^2 = 50.24)

Divide the area of the circle by 2 since it is a semi circle (50.24 / 2 = 25.12)

Add the area of the two (25.12 + 80 = 105.12)

Answer:

2nd and 4th are parallel

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Given

3y + x = 5 ( subtract x from both sides )

3y = - x + 5 ( divide terms by 3 )

y = - [tex]\frac{1}{3}[/tex] x + [tex]\frac{5}{3}[/tex] ← in slope- intercept form

with slope m = - [tex]\frac{1}{3}[/tex]

-------------------------------------------------------

x - 3y = 12 ( subtract x from both sides )

- 3y = - x + 12 ( divide terms by - 3 )

y = [tex]\frac{1}{3}[/tex] x - 4 ← in slope- intercept form

with slope m = [tex]\frac{1}{3}[/tex]

-------------------------------------------------------

y = 3x - 2 ← in slope- intercept form

with slope m = 3

---------------------------------------------------------

6y - 2x = 7 ( add 2x to both sides )

6y = 2x + 7 ( divide terms by 6 )

y = [tex]\frac{1}{3}[/tex] x + [tex]\frac{7}{6}[/tex] ← in slope- intercept form

with slope m = [tex]\frac{1}{3}[/tex]

--------------------------------------------------------

Parallel lines have equal slopes.

The 2nd and 4th have equal slopes and are parallel

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

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}

The factorization of x2 - 6x + 5 is (x - 1)(x -5)

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)

Answer: A. preserves length, angle measures and distance between points

Rigid motions or isometries are any of the three transformations below

Any 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.

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.

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.

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

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]

Answer:

x = 20

Step-by-step explanation:

180° = total

3 = amount of angles

180 ÷ 3 = 60°

60° + 60° + 3x = 180°

120° + 3x = 180

3x = 180 - 120

3x = 60

x = 20
