A date in March is chosen at random, then the spinner below is spun once. Find the probability of an odd number, and then blue. Use the counting principle to find the probability.

Answers

Answer 1

The probability of randomly selecting a date in March and spinning the spinner once, resulting in an odd number and then blue, is 1/6.

To find the probability of an odd number and then blue, we need to consider the number of favorable outcomes for each event and the total number of possible outcomes.

Probability of an odd number:

The spinner has 6 equally likely outcomes (numbers 1 to 6), and out of these, 3 are odd numbers (1, 3, and 5).

Therefore, the probability of getting an odd number is 3/6, which simplifies to 1/2.

Probability of blue:

The spinner has 6 equally likely outcomes, and out of these, 2 are blue. Therefore, the probability of getting blue is 2/6, which simplifies to 1/3.

To find the probability of both events occurring, we multiply the probabilities of each event:

Probability of an odd number and then blue [tex]= Probability $ of an odd number \times Probability $ of blue[/tex]

[tex]= (1/2) \times (1/3)[/tex]

= 1/6.

Answers

Θ(x) = tan⁻¹(5x / (4(x - 13))), and Θ is maximized when the distance the cow must stand from the billboard x₀ = 26.

How to determine angle and distance?

To find Θ, use similar triangles. Let the distance from the cow to the top of the billboard be h. Then, using similar triangles:

h / x = 5 / (x - 13)

Solving for h:

h = 5x / (x - 13)

The vertical angle subtended by the billboard at the cow's eye is equal to the angle whose tangent is given by:

tan(Θ) = h / 4

Substituting for h:

tan(Θ) = 5x / (4(x - 13))

To maximize Θ, find the value of x that maximizes tan(Θ). Taking the derivative of tan(Θ) with respect to x and setting it equal to zero:

d/dx (tan(Θ)) = 5(52 - 26x) / (4(x - 13))² = 0

Solving for x:

x₀ = 26

Substituting x₀ into the expression for Θ:

Θ(x₀) = tan⁻¹(5(26) / 4(13)) = tan⁻¹(5/2)

Therefore, Θ(x) = tan⁻¹(5x / (4(x - 13))), and Θ is maximized when x₀ = 26.

the mean radius of the earth is 6371.0 kilometers and the mean radius of earths moon is 1737.5 kilometers. what is the approximate difference in the mean circumferences in kilometerse of the earth and earths moon

Answers

the approximate difference in the mean circumferences of the Earth and the Moon is about 29153.88 kilometers.

Describe circle.

A circle is a particular type of ellipse in mathematics or geometry where the eccentricity is zero and the two foci are congruent.

A circle is also known as the location of points that are evenly spaced apart from the centre. The radius of a circle is measured from the centre to the edge. T

he line that splits a circle into two identical halves is its diameter, which is also twice as wide as its radius.

A circle is a fundamental 2D form whose radius is quantified. The interior and exterior parts of the aircraft are separated by the circles.

The formula for the circumference of a circle is:

C = 2πr

where C is the circumference, π (pi) is a constant approximately equal to 3.14, and r is the radius.

The difference in the mean circumferences of the Earth and the Moon can be found by subtracting the circumference of the Moon from the circumference of the Earth.

The circumference of the Earth is:

C earth = 2π * 6371.0 km = 40075.04 km (rounded to two decimal places)

The circumference of the Moon is:

C moon = 2π * 1737.5 km = 10921.16 km (rounded to two decimal places)

The difference in the mean circumferences of the Earth and the Moon is:

C earth - C moon = 40075.04 km - 10921.16 km ≈ 29153.88 km

Therefore, the approximate difference in the mean circumferences of the Earth and the Moon is about 29153.88 kilometers.

= (2x)² + 2(2x)(1) + 1² + (4x)² - 2(4x)(4) + 4² (using the formula for the square of a binomial)

Answers

Answer:(a) The rate of decay is 14.4% per day, which can be written as a decimal by dividing by 100: r = 0.144.

(b) The formula for continuous decay is given by:

A = A₀ * e^(-rt)

where A is the remaining amount of the substance after time t, A₀ is the initial amount, r is the rate of decay, and e is the mathematical constant approximately equal to 2.71828.

Plugging in the given values, we get:

A = 140 * e^(-0.144*15)

A = 140 * e^(-2.16)

When doubling the dimensions of a rectangle, why does the area quadruple and the perimeter only doubles?

Answers

If you double the length and the width, you are quadrupling the area.

This is because 2 × 2 = 4.

Perimeter of new rectangle=   2 × perimeter of initial rectangle.

The perimeter will be double of if we double the length and breadth of rectangle

→ When doubling the dimensions of a rectangle, why the area is quadruple:

We know that :

Area of rectangle = l × b

where, l is length and b is breadth

A = L × W

This means area equals length times width.

if you double the length and you double the width, the formula becomes:

A = 2 × L × 2 × W

A = 2 × 2 × L × W

A = 4 × L × W

if you double the length and the width, you are quadrupling the area.

This is because 2 × 2 = 4.

→When doubling the dimensions of a rectangle, why the perimeter is doubles?

Let length be equal to ′l′

And breadth be equal to ′b′

Perimeter of rectangle = 2 (l + b) ____(equation i )

The perimeter if the length and breadth of the rectangle will increase by two, or will it double? So new parameters of rectangle when its length and breadth will get double on initial one.

Double length of rectangle of initial one= 2 × l=2l

Double breadth of rectangle of initial one = 2×b=2b

So the perimeter of new rectangle whose length and breadth are double of initial one are:

As we know that:

Perimeter of rectangle = 2 (l + b)

So,

Perimeter of new rectangle= 2(2l+2b),  (by taking 2 common)

Perimeter of new rectangle = 2×2(l + b) ____  equation (ii)

As from equation (i) perimeter of initial rectangle is = 2(l + b)

So from equation (i) and (ii)

Perimeter of new rectangle= 2 × 2(l + b)

Perimeter of new rectangle=   2 × perimeter of initial rectangle.

Hence, the perimeter will be double of if we double the length and breadth of rectangle.

Rationalize the denominator and simplify:
4/4+√x

Answers

Answer: 16-4√x/16-x is the answer.

Step-by-step explanation:

=> 4/4+√x*4-√x/4-√x

=> 4(4-√x)/(4)²-(√x)²  {using identity - (a+b) (a-b)=a² - b²}

=> 16-4√x/16-x

Out of 400 people sampled, 160 preferred

Answers

To estimate the proportion of the voting population that prefers Candidate A, we can use a point estimate and a confidence interval. The point estimate is the sample proportion, which is:

p-hat = 160/400 = 0.4

To construct a confidence interval for the true proportion p, we can use the following formula:

p-hat ± z*sqrt(p-hat*(1-p-hat)/n)

where z is the critical value for the desired confidence level, sqrt is the square root function, and n is the sample size.

At a 90% confidence level, the critical z-value is 1.645. Substituting the given values, we get:

0.4 ± 1.645*sqrt(0.4*(1-0.4)/400)

Simplifying this expression, we get:

0.4 ± 0.052

Therefore, the 90% confidence interval for the true proportion p is (0.348, 0.452).

This means that we can be 90% confident that the proportion of the voting population that prefers Candidate A is between 0.348 and 0.452.

The value of the "trigonometric-expressions' are :

(a) tan(5π/2) is undefined,

(b) sec(315°) is √2.

Part(a) : The expression "tan(5π/2)" is undefined because the tangent function is undefined at odd multiples of π/2, which includes 5π/2.

Part(b) : To find the value of sec(315°), we use the identity: sec(θ) = 1/cos(θ),

First, we convert 315° to radians:

Which is : 315° = (7π/4) radians;

Next, we find the value of cos(7π/4):

⇒ cos(7π/4) = cos(π/4) = (√2)/2;

Finally, we substitute in the identity for sec(θ);

So, Sec(7π/4) = 1/cos(7π/4) = 1/[(√2)/2] = √2.

Therefore, value of sec(315°) is √2.
