Answer 1

Answer:

Angle ABC = 82°

Step-by-step explanation:

Given triangle ABC is an isosceles triangle so we can write

angle BAC = angle BCA = 49°

Then,

angle BAC + angle BCA + angle ABC = 180° (Sum of all angles of a triangle is 180°)

or, 49° + 49° + angle ABC = 180°

or, angle ABC = 180° - 98°

or, angle ABC = 82°

In an ESP experiment subjects must predict whether a number randomly generated by a computer will be odd or even. (Round your answer to four decimal places.) (b) What is the probability that a subject would guess more than 20 correct in a series of 36 trials?

Answers

The probability that a subject would guess more than 20 correct in a series of 36 trials is 0.0001

How to find the pobability that a subject would guess more than 20 correct in a series of 36 trials

In a series of 36 trials, if the subject is guessing randomly, then the probability of correctly guessing odd or even is 1/2.

Let X be the number of correct guesses in a series of 36 trials. X follows a binomial distribution with parameters n = 36 and p = 1/2.

The probability of guessing more than 20 correct is:

P(X > 20) = 1 - P(X ≤ 20)

Using a binomial distribution table, we can find that P(X ≤ 20) = 0.9999 (rounded to four decimal places).

Therefore: P(X > 20) = 1 - 0.9999 = 0.0001

So the probability that a subject would guess more than 20 correct in a series of 36 trials is 0.0001 (rounded to four decimal places).

Step-by-step explanation:

An acre is a unit of measure for area. One acre ie equal to 43,560 square feet. Often, an acre is a rectangle that measures 660 feet by 66 feet. However, the length and width of the rectangle can vary. An acre can actually have any shape, as long as it measures exactly 43,560 square feet. Rachel purchased 1/5 acre of land in the shape of an isosceles triangle. What is the area of the land Rachel purchased?

Answers

Answer:

area of land purchased =247

The area of the land Rachel purchased is approximately 10,055.64 square feet.

How to calculate the area?

We can start by finding the area of one acre in square feet, which is given as 43,560 square feet.

To find the area of 1/5 acre, we can divide 43,560 by 5, which gives us 8,712 square feet.

Since Rachel's land is in the shape of an isosceles triangle, we need to find the base and height of the triangle in order to calculate its area. Let's call the length of the base "b" and the height "h".

We know that the area of a triangle is given by the formula:

Area = (1/2) x base x height

So, we can rearrange this formula to solve for the height:

height = 2 x Area / base

Now we can substitute in the values we know:

Area = 8,712 square feet

base = unknown

height = unknown

We also know that the triangle is isosceles, which means that two of the sides are equal in length. Let's call the length of one of these sides "s". Then the length of the base can be expressed in terms of s as:

base = 2s

We can use the Pythagorean theorem to find the height in terms of s:

s² + (h)² = (2s)²

s² + h² = 4s²

h² = 3s²

h = s x √(3)

Now we can substitute this expression for the height in terms of s into the formula we derived for the area:

Area = (1/2) x base x height

Area = (1/2) x 2s x s x √(3)

Area = s² x √(3)

We know that the area of the triangle is 1/5 of an acre or 8,712 square feet, so we can set this equal to the expression we just derived for the area and solve for s:

s² x √(3) = 8,712

s² = 8,712 / √(3)

s = √(8,712 / √(3))

Now that we know the length of one of the equal sides of the isosceles triangle, we can find the length of the base by multiplying by 2:

base = 2s

base = 2 x √(8,712 / √(3))

Finally, we can substitute in the values we just found for the base and height into the formula for the area of the triangle:

Area = (1/2) x  base x height

Area = (1/2) x 2 x √(8,712 / √(3)) x √(3) x √(8,712 / √(3))

Area = 2 x 8,712 / √(3)

Area = 17,424 / √(3)

Therefore, the area of the land Rachel purchased is approximately 10,055.64 square feet.

How to obtain the value of x?

A chord of a circle is a straight line segment that connects two points on the circle, that is, it is a line segment whose endpoints are on the circumference of a circle.

When two chords intersect each other, then the products of the measures of the segments of the chords are equal.

Hence the value of x is obtained as follows:

12x = 15 x 8

12x = 120

The sector of a circle has an area of 104pi/9
square inches and a central angle with measure 65 degree
. What is the radius of the circle, in inches?

Answers

Answer:

Given:

Area of the sector (A) = 104π/9 square inches

Central angle (θ) = 65 degrees

The formula for the area of a sector of a circle is:

A = (θ/360) * π * r^2

We can rearrange this formula to solve for the radius (r):

r^2 = (A * 360) / (θ * π)

Plugging in the given values:

r^2 = (104π/9 * 360) / (65 * π)

r^2 = (104 * 40) / 9

r^2 = 4160 / 9

r^2 ≈ 462.22

Taking the square root of both sides:

r ≈ √462.22

r ≈ 21.49

Therefore, the radius of the circle is approximately 21.49 inches.

Answers

The function at its maximum value will be at point (11,4) and its value is 52 which can be derived keeping in mind the constraints that have been given.

Maximizing a function

The maximum value of any kind of a function is the place where the said function reaches its highest point, or vertex, on a graph. If your kind of quadratic equation has something as a negative of a term, it will also have a maximum value.

There are a bit of three ways to find that maximum, depending on which form of a quadratic function you have got.

Herein we can find the closed region ABC from the three equations or constraints given

and can mark the points as

A = (5,4)

B = (5, 12)

C = (11, 4)

if we put up the values of the points, we get

at (11, 4), Z = 4 x 11 + 2 x 4

=52 that is the maximum value amongst the three.

Thus, the maximum point of the function can be calculated as (11,4)

How do you extract out the maximum or minimum value of a function?

We will at first set out the first derivative of the function to absolute zero and then solve for x to get the exact critical point.

If we then take the second derivative or f’’(x), there in we can find out whether this point will be a maximum or minimum. If the second derivative is seen as positive, it will be a minimum value

What is the maximum value of a function called?

The maximum or minimum value that is calculated over the entire function is called an “Absolute” or “Global” maximum or minimum of the function.

There is presence of only one global maximum (and only one global minimum) but there can be several that is more than one local maximum or minimum

what is the equation of a line that passes through the points (2,5) and (4,3)

Answers

The equation of a line that passes through points (2,5) and (4,3) is

y = -x+7.

Finding the equation of a line:

First, we need to find out the slope for the given points.

(X1,Y1) = (2,5)

(X2,Y2) = (4,3)

formula for slope(m) = \(\frac{Y2 - Y1}{X2 - X1}\)

substitute the points in the above formula

\(\frac{3 - 5}{4 - 2}\) = \(\frac{-2}{2}\)

\(\frac{-2}{2}\) = -1

slope for the given points(m) = -1.

m = -1

The equation of a line is y-y1 = m(x-x1), where x and y are variables.

substituting the values in the above equation then :

y-5 = -1(x-2)

y-5 = -x+2

y+x = 2+5

x+y = 7

y = -x+7

Therefore, the equation of the line passing through the points (2,5) and (4,3) is y = -x+7

value of the vehicle 10 years after purchase. Round to the nearest whole dollar.

Answers

After 10 years the depreciation value of the vehicle will be $12700.

What is percentage(%)?

A %(percentage) is a number that indicates how many out of 100 it is, and it can also be expressed as a decimal or a fraction. Put the percentage value in the numerator and 100 in the denominator to convert a percentage to a fraction.

\(V(t) = V0*(1-rate)^t\)

V(t) is the value at year t (we want t =10 years)

V0 is the starting value = $20,700

rate is the depreciation rate expressed as a decimal = 0.05

t = years = 10

\(V(10) = $20700*(1 - 0.05)^{10}\)

= 20700*(0.95)^10

= 20700*(0.598)

Explanation:

The general form of the slope-intercept form of the equation of a line is given as;

\(y=mx+b\)

where m = slope of the line

b = y-intercept of the line

Given the below function;

\(f(x)=-\frac{3}{4}x+1\)

If we compare both equations, we can see that the slope(m) = -3/4 and the y-intercept(b) = 1. It means that the graph will have a negative slope will cut the y-axis at y = 1.

Given;

\(g(x)=-\frac{1}{2}x-1\)

We can deduce that the slope(m) of this line = -1/2 and the y-intercept(b) = -1. It means that the graph of this line will also have a negative slope and will cut the negative y-axis at y = -1.

See below the graph of both lines;

From the above graph of both functions, we can see that the two lines intersect at x = 8.

Therefore the value of x for which f(x) = g(x) is 8.8
