Answer:

135 :)

Step-by-step explanation:

15 divided by 1/9 is equal to 135.

We have,

When dividing fractions, we can invert the second fraction (1/9) and multiply it by the first fraction (15).

This concept is known as "invert and multiply."

By multiplying 15 by the reciprocal of 1/9, which is 9/1, we effectively perform the division operation and obtain the result.

Now,

To divide 15 by 1/9, we can rewrite the division as a multiplication by the reciprocal of the second fraction.

15 ÷ (1/9) is the same as 15 * (9/1).

Multiplying these fractions, we get:

15 * (9/1) = 135/1 = 135.

Therefore,

15 divided by 1/9 is equal to 135.

Answer:

42 sq. Units

Step-by-step explanation:

I took the test

The area of the triangle shown below is B. 42 sq. units, the correct option is B.

The area of the triangle is defined as the product of half the base and the height of the triangle.

We are given the parameters are;

Length of its base = b units

Its height = h units long,

Then we get:

Area of a triangle = 1/2 b h

We are given that;

Base= 14, Height= 6

Now,

The area of a right triangle is given by:

Area = (1/2) * base * height

Substituting the values;

Area = (1/2) * 14 * 6

= 42 square units

Therefore, the area of triangle will be 42 sq. units.

(L2) An inscribed circle is one that encompasses a polygon so that it passes by each of the polygon's vertices.

A circumcircle, not an inscribed circle, is a circle that encircles a polygon at each vertex. A circle that is enclosed within a polygon and intersects each side of the polygon exactly once is said to be inscribed. A circumcircle, on the other hand, is a circle that goes through every vertex of the polygon, with its center located at the point where the perpendicular bisectors of the polygon's sides converge. The greatest circle that can be drawn within a polygon is the circumcircle, while the largest circle that can be drawn inside a triangle is the inscribed circle.

To find the length of the hypotenuse c in a right triangle with legs a = 16 and b = 30, we can use the Pythagorean theorem:

c^2 = a^2 + b^2

Substituting the given values, we get:

c^2 = 16^2 + 30^2

c^2 = 256 + 900

c^2 = 1156

Taking the square root of both sides, we get:

c = √1156

c ≈ 34.0 (rounded to the nearest tenth)

Therefore, the length of the hypotenuse c in the right triangle is approximately 34.0 units.

A quadratic equation is a polynomial equation of degree 2, which means the highest power of the variable in the equation is 2. Quadratic equations have a variety of applications in mathematics, physics, engineering, and other fields.

To prove the statement that the product of the solutions of the quadratic equation ax²+bx+c = 0 is c/a using the Quadratic Formula, let's break it down step-by-step:

1. The Quadratic Formula states that the solutions of a quadratic equation in the form ax²+bx+c = 0 are given by:

  x = (-b ± √(b²-4ac)) / (2a)

2. Let's substitute these values into the formula and solve for the solutions:

  x₁ = (-b + √(b²-4ac)) / (2a)
  x₂ = (-b - √(b²-4ac)) / (2a)

3. To find the product of the solutions, we multiply x₁ and x₂:

  x₁ * x₂ = [(-b + √(b²-4ac)) / (2a)] * [(-b - √(b²-4ac)) / (2a)]

4. Simplifying the expression, we can apply the distributive property:

  x₁ * x₂ = [(-b)² - (√(b²-4ac))²] / (2a)²
  x₁ * x₂ = (b² - (b²-4ac)) / (4a²)
  x₁ * x₂ = (b² - b² + 4ac) / (4a²)
  x₁ * x₂ = 4ac / (4a²)

5. Cancelling out the common factor of 4, we get:

  x₁ * x₂ = ac / a²

6. Finally, we can simplify the expression by dividing both the numerator and denominator by a:

  x₁ * x₂ = c / a

Therefore, we have proved that the product of the solutions of the quadratic equation ax²+bx+c = 0 is indeed c/a using the Quadratic Formula.

This means that for any quadratic equation in the form ax² + bx + c = 0, the product of its solutions is equal to c/a.

To prove the statement using the Quadratic Formula, let's start by considering the quadratic equation ax² + bx + c = 0. We know that the quadratic formula can be used to find the solutions (or roots) of this equation, given by:
x = (-b ± √(b² - 4ac)) / (2a)
Now, let's find the product of the solutions using the quadratic formula. We'll denote the two solutions as x₁ and x₂.
The product of the solutions is given by:
x₁ * x₂ = [(-b + √(b² - 4ac)) / (2a)] * [(-b - √(b² - 4ac)) / (2a)]
To simplify this expression, we'll multiply the numerators and the denominators:
x₁ * x₂ = (-b + √(b² - 4ac)) * (-b - √(b² - 4ac)) / (2a) * (2a)
Expanding the numerator by using the distributive property:
x₁ * x₂ = (b² - (b² - 4ac)) / (4a²)
Simplifying the numerator:
x₁ * x₂ = (b² - b² + 4ac) / (4a²)
Cancelling out the b² terms:
x₁ * x₂ = 4ac / (4a²)
Simplifying further:
x₁ * x₂ = c/a
Thus, we have proven that the product of the solutions of the quadratic equation ax² + bx + c = 0 is indeed c/a.

2. Total weight that can be carried is 3000 pounds.

The big machine is 300 pounds. The weight that the truck can carry beside the big machine is 3000-300= 2700 pounds.

The smaller machines weigh 60 pounds

The number of smaller machines that can be carried is 2700 ÷ 60= 45 other than the big machine.

3. Total distance = Speed * time

                           = 48 * (40/60) = 32 miles

New distance = 32+ 8= 40 miles

New time = 48 minutes

Speed = distance / time = 40/ 48/60=  50 miles per hour

Heritability is a statistic that quantifies the proportion of observed variance in a group of individuals that can be attributed to genetic variance.

Heritability is a fundamental concept in genetics and behavioral sciences that helps understand the extent to which genetic factors contribute to observed variations in a particular trait within a population. It measures the proportion of phenotypic variation (differences in traits) that can be explained by genetic variation. Heritability estimates range from 0 to 1, where a value of 0 indicates that all observed variation is due to environmental factors, and a value of 1 suggests that all observed variation is due to genetic factors.

To calculate heritability, researchers typically study populations with varying degrees of genetic relatedness, such as twins or family members. By comparing the similarity of traits between individuals with known genetic relatedness, it is possible to estimate the contribution of genetic factors to the observed variance. Environmental factors that contribute to phenotypic variation are considered as part of the non-genetic or "environmental" component.

It is important to note that heritability estimates are population-specific and apply only to the particular group being studied. Additionally, heritability does not provide information about specific genes or the precise mechanisms by which genetic factors influence traits. Nonetheless, heritability serves as a valuable tool in understanding the relative importance of genetic and environmental factors in shaping individual differences within a population.

Answer:

\(\approx 45.1\:\mathrm{w/\: some \: MOE}\)

Step-by-step explanation:

The area of \(ABCD\) is comprised of two triangles, so we can find the area of both triangles and add them to get the total area of

Since the sum of the interior angles of a triangle add up to \(180^{\circ}\), we have:

\(\angle C=180-44-38=\fbox{$98^{\circ}$}\).

The Law of Sines is given as:

\(\frac{\sin A}{a}=\frac{\sin B}{b}=\frac{\sin C}{c}\) for any triangle.

Therefore, we have the proportion:

\(\frac{\sin 98^{\circ}}{10}=\frac{\sin 44^{\circ}}{BC},\\BC=\frac{10\cdot \sin 44^{\circ}}{\sin 98^{\circ}},\\BC\approx 7.01\).

Now that we have two sides of a triangle and the angle between them, we can use \([\triangle]=\frac{1}{2}ab\sin C\)  to find the area of \(\triangle CBD\):

\([CBD]=\frac{1}{2}\cdot 10\cdot 7.01 \cdot \sin 38^{\circ},\\\\\left [CBD]\right\approx 21.58\).

Since \(\triangle ABD\) is a right triangle, we can use basic trig rules for a right triangle to solve for the sides:

\(\sin 55^{\circ}=\frac{AB}{10},\\AB=10\sin 55^{\circ},\\AB\approx 8.19\),

\(\sin 35^{\circ}=\frac{AD}{10},\\AD=10\sin 35^{\circ},\\AD\approx 5.74\).

Therefore, the area of \(\triangle ABD\) is:

\(\frac{1}{2}\cdot 8.19\cdot 5.74\approx 23.49\).

The area of \(ABCD\) is then

\(21.58+23.49=45.07=\fbox{$45.1$}\).

\(\bigstar\) Note that intermediate results were rounded during this calculation. Therefore, there is a small margin of error when rounding to final answer to one decimal place. I recommend plugging in values for yourself using all equations I wrote above, then rounding only your final answer to one decimal place as requested by the problem.

the function f(x) is differentiable everywhere when a = -3 and b = 16, and is given by:

f(x) = { x^2 - 2x + 2 if x <= -2

{ -3x + 16     if x > -2

For the function f(x) to be differentiable everywhere, we need the two pieces of the function to "match up" at x = -2, i.e., they should have the same value and derivative at x = -2.

First, we evaluate the value of f(x) at x = -2 using the second piece of the function:

f(-2) = a(-2) + b

Since the first piece of the function is given by f(x) = x^2 - 2x + 2, we can evaluate the left-hand limit of f(x) as x approaches -2:

lim x->-2- f(x) = lim x->-2- (x^2 - 2x + 2) = 10

Therefore, we must have:

f(-2) = lim x->-2- f(x) = 10

a(-2) + b = 10

Next, we need to make sure that the two pieces of the function have the same derivative at x = -2. The derivative of the first piece of the function is:

f'(x) = 2x - 2

Therefore, we have:

lim x->-2+ f'(x) = lim x->-2+ 2a = f'(-2) = 2(-2) - 2 = -6

So, we must have:

lim x->-2+ f'(x) = lim x->-2+ 2a = -6

2a = -6

a = -3

Finally, substituting the values of a and b into the equation a(-2) + b = 10, we get:

-6 + b = 10

b = 16

Therefore, the function f(x) is differentiable everywhere when a = -3 and b = 16, and is given by:

f(x) = { x^2 - 2x + 2 if x <= -2

  { -3x + 16     if x > -2

Given statement solution is :- If I were to assume the flipping process is entirely random and the coin is unbiased, the chances of correctly guessing the outcome of each flip would be 1 out of 2, or a 50% probability.

If I were to assume the flipping process is entirely random and the coin is unbiased, the chances of correctly guessing the outcome of each flip would be 1 out of 2, or a 50% probability. However, the psychic claims to have the ability to sense the outcome of each flip, which would suggest that he believes he can accurately predict the results.

To put the psychic to the test, you can proceed with flipping the coin six times and ask the psychic to guess the outcome of each flip. After the coin has been flipped, compare the psychic's guesses with the actual outcomes to evaluate the accuracy of their predictions.

Keep in mind that even if the psychic does make correct predictions, it does not necessarily prove their psychic abilities. Random chance can occasionally lead to a streak of correct guesses, even if there is no true psychic ability involved. To draw any meaningful conclusions, a larger sample size or repeated testing would be required.
