The probability of getting at least 1 red is 6/7

Probability is the likelihood of a desired event happening.

Theoretical probability is the theory behind probability. To find the probability of an event, an experiment is not required. Instead, we should know about the situation to find the probability of an event occurring.

The probability that the first is blue and the second is blue

p(First blue, Second blue) = 3/7 × 2/6 = 1/7

Thus, the probability of getting at least 1 red, is the complement of getting both blue

That is, P(At least 1 red) = P'(both blue) = 1 - P(Both blue) = 1 - 1/7 = 6/7

Answer:

12 1/30

Step-by-step explanation:

Sum is the term used for the total amount of something when two or more numbers are added.

In order to add the two fractions, they must have the same denominator.

To do this, we need to find a common denominator.

Multiples of 3:  3, 6, 9, 12, 15, 18, 21, 24, 27, 30

Multiples of 10:  10, 20, 30

Both 3 and 10 have 30 in common, so this is the common denominator.

In order to get to 30, 3 must be multiplied by 10.  Whatever you do to the bottom must be done to the top and vice versa.

7 1/3 becomes 7 10/30.

4 7/10 becomes 4 21/30

Now, we add the whole numbers.

7 + 4 = 11

Now, add the fractions.

10/30 + 21/30 = 31/30

Put it all together.

11 31/30

This is an improper fraction, so we must make it a proper fraction.  To do this, we divide 30 into 31.  It can only go in evenly one time and has a remainder of one.  The remainder is added to the whole numbers and the numerator of the fraction takes the evenly divided one.

11 + 1 1/30  This is adding the remainder to the whole number.

12 1/30  This is the result of adding the remainder and fixing the fraction.

12 1/30 is the answer.

To find the volume of water flowing out of the pipe every second, we first need to find the cross-sectional area of the pipe. The formula for the area of a circle is π * r^2, where r is the radius. So, the radius of the pipe is 8/2 = 4 inches.

The cross-sectional area of the pipe is π * 4^2 = 16π square inches.

Now, since the water is flowing at a rate of 2 feet per second, and 1 foot is equal to 12 inches, the flow rate in inches per second is 2 * 12 = 24 cubic inches per second.

So, the exact volume of water flowing out of the pipe every second is the cross-sectional area of the pipe times the flow rate:

16π * 24 = 384π cubic inches per second.

Answer:

1st question:

10°, 80°, 90°

2nd question:

76°, 52°, 52°

Step-by-step explanation:

For both of these questions we will use the idea that the three angles of a triangle add up to 180°.

In the triangle on the left, two angles are marked and the third is a right angle. The tiny square marking on the third angle means it is a right angle, so it is 90°.

We can write an equation.

x + 8x + 90° = 180°

combine like terms

9x + 90 = 180

subtract 90

9x = 90

divide by 9

x = 10

So the angles are x, 8x and 90°

Since x = 10

the 3 angles are 10°, 80° and 90°

For the second question, two sides are marked to show they are congruent (same, equal) that means the two angles on the base (base angles) are congruent (the same)

One angle is 3x+1 and both the other two angles are 2x+2. Write an equation.

3x+1 + 2x+2 + 2x+2 = 180°

combine like terms

7x + 5 = 180

subtract 5

7x = 175

divide by 7

x = 25

Calculate the angle measures using x = 25

3x+1 = 3(25)+1 = 76°

2x+2 = 2(25)+2 = 52°

The 3 angles of the triangle are 76°, 52° and 52°

A possible vector function that represents the curve of intersection of the two surfaces is r(t) = (5 cos(t), 5 sin(t), 5 cos(t) sin(t))

The cylinder x^2 + y^2 = 25 represents the set of points in 3D space where the distance from the origin to the point (x, y, z) is equal to 5. The surface z = xy represents the set of points in 3D space where the height of the point (x, y, z) is equal to its x-y coordinate.

The curve of intersection of the two surfaces is given by the set of points in 3D space that are simultaneously on the cylinder and on the surface z = xy. This means that for any point on the curve of intersection, the distance from the origin to the point must be equal to 5, and the height of the point must be equal to its x-y coordinate.

We can find a vector function that represents the curve of intersection by parameterising the points on the curve in terms of a scalar parameter t. For example, a possible parameterization of the curve of intersection is:

r(t) = (5 cos(t), 5 sin(t), 5 cos(t) sin(t))

where t is a scalar parameter that ranges over all values between 0 and 2π. The values of x, y, and z are given by 5 cos(t), 5 sin(t), and 5 cos(t) sin(t), respectively, and represent a point on the curve of intersection for each value of t.

The function that models the mass of the carbon-14 sample remaining {t} years since the initial measurement is → M{t} = 960 - 0.012t.

Given is that Carbon-14 is an element which loses (1/10) of its mass every 871 years. The initial mass of a sample of Carbon-14 is 960 grams. The mass of a sample of carbon-14 can be modeled by a function {M} which depends on its age {t} (in years).

(1/10) x 96 = 96/10 = 9.6 grams.

Carbon - 14 looses 9.6 grams in 871 years.

In 1 year, Carbon - 14 will loose (9.6/871) = 0.012 gram.

We can write the function {M} as -

M{t} = 960 - 0.012t

Therefore, the function that models the mass of the carbon-14 sample remaining {t} years since the initial measurement is → M{t} = 960 - 0.012t.

[tex]g(x)=Ae^{-2x}[/tex]

Infinity divided by infinity is undefined because infinity is not a number and cannot be treated as one in mathematical operations. In mathematics, division is a process that involves finding the ratio between two numbers. However, infinity is not a number and has no finite value, so it cannot be used as the denominator or numerator in a division operation.

When dividing infinity by infinity, you are asking for the ratio of two quantities that are both infinite, and the result is not well-defined. The concept of infinity can be useful in certain mathematical contexts, such as limits and calculus, but it cannot be used as a number in the usual sense.

In mathematical terms, the expression infinity divided by infinity is considered indeterminate and has no defined value. This is why it is undefined in mathematical analysis.

Therefore , the solution of the given problem of triangle comes out to be it shares an angle with triangle DEF that is equal in measure to angle F.

If a triangle has four quadrants or more, it is referred to as a polygon. It has a straightforward rectangular shape. The letters ABC when combined form a right-angled triangular. A new parallelogram with rectangular shape corners is created by Euclidean geometry when the limits are incompatible. Due to their three edges but also three points, triangles are categorised as polygons. The location of a triangle's corners is determined by where its three edges meet. The sum of the angles on the inside of a trapezoid is 180.

Here,

Part A: To determine if triangle DEF is similar to triangle DBC, we need to check if their corresponding angles are equal in measure and if their corresponding sides are proportional. If both conditions are satisfied, the triangles are similar. Since BC is parallel to EF, we know that angle DBC and angle DEF are corresponding angles and are therefore equal in measure.

Part B: The line segment on triangle DBC that corresponds to line segment EF is the side opposite to angle DBC, which is segment DC. This is because segment DC is parallel to segment EF and shares an angle with triangle DEF that is equal in measure to angle DBC.

Part C: The corresponding angle to angle F in triangle DBC is angle BCD. This is because angle BCD is opposite to side BC, which is parallel to EF and shares an angle with triangle DEF that is equal in measure to angle F.

The formula to calculate the future value of an investment with compound interest is:

FV = PV * (1 + (r/n))^(n*t)

Where:

PV is the present value (the initial investment)

r is the annual interest rate

n is the number of compounding periods per year

t is the number of years

For Investment A:

PV = $4,000

The smallest integer a such that the intermediate value theorem guarantees that f(x) has a zero on the interval [0, a] is 2.

The intermediate value theorem states that if a function f is continuous on the closed interval [a, b] and if y is a value between f(a) and f(b), then there exists a point c in the interval [a, b] such that f(c) = y.

In this case, we want to find the smallest integer a such that f(x) has a zero on the interval [0, a]. Since f(0) = 7 and f(x) = -2x^3 + 8x^2 - 6x + 7, we need to find the smallest a such that f(a) < 0.

We can start by finding the values of x where f(x) changes sign. To do this, we can set f(x) equal to 0 and solve for x:

-2x^3 + 8x^2 - 6x + 7 = 0

This is a cubic equation and can be solved using various methods such as factoring, substitution, or the use of a numerical method. However, since we are looking for the smallest integer a, we can use an estimation method such as the Newton-Raphson method to approximate the smallest positive root of the equation.

A common initial guess for the smallest positive root of a cubic equation is x = 1. Using this as the initial guess, we can iterate using the following formula:

x_{n+1} = x_n - f(x_n)/f'(x_n)

where f'(x) is the derivative of f(x) and x_n is the nth estimate of the root.

After several iterations, the estimate for the smallest positive root of the equation can be found to be approximately 1.56. Therefore, the smallest integer a such that the intermediate value theorem guarantees that f(x) has a zero on the interval [0, a] is 2.
