Answer:

The value of x is 37.36

Step-by-step explanation:

The given triangle is a right-angled triangle where

Base = 25

Angle = 48°

Hypotenuse = x

As the triangle is a right angled triangle, trigonometric ratios can be used to find the missing value. We can use a ratio which uses base and hypotenuse.

\(cos\ 48 = \frac{base}{hypotenuse}\\cos\ 48 = \frac{25}{x}\\0.6691 = \frac{25}{x}\\x = \frac{25}{0.6691}\\x = 37.36\)

Hence ,

The value of x is 37.36

The probability of the baseball player getting exactly 4 hits out of 10 times at bat is approximately 0.161, or 16.1%.

To calculate the probability of a baseball player getting exactly 4 hits out of 10 times he was up at bat, we need to use the binomial probability formula.

The binomial probability formula is given by:P(X = k) = C(n, k) * p^k * (1 - p)^(n - k)

Where:

P(X = k) is the probability of getting exactly k hits

n is the total number of trials (in this case, the player's 10 times at bat)

k is the number of successful trials (in this case, 4 hits)

p is the probability of success in a single trial (in this case, the player's batting average, 0.298)

(1 - p) is the probability of failure in a single trial

Plugging in the values:

P(X = 4) = C(10, 4) * (0.298)^4 * (1 - 0.298)^(10 - 4)

Using the combination formula C(n, k) = n! / (k! * (n - k)!):

P(X = 4) = 10! / (4! * (10 - 4)!) * (0.298)^4 * (1 - 0.298)^(10 - 4)

Calculating the values:

P(X = 4) ≈ 0.161

The area of the shaded region of a circle with a 100 degree angle and a radius of 3cm, using pi=3.14, is approximately 25.64 square centimeters.

To find the area of the shaded region of a circle, we need to subtract the area of the sector formed by the shaded region from the area of the whole circle.

The area of the whole circle is given by

A = πr²

where A is the area of the circle, r is the radius of the circle, and π is a mathematical constant approximately equal to 3.14 (as given in the question).

Substituting the given values, we get

A = π(3cm)²

A = 28.26 cm² (rounded to two decimal places)

Now, let's find the area of the sector formed by the shaded region.

The angle of the sector is given as 100 degrees. To find the area of the sector, we need to use the formula:

A = (θ/360)πr²

where θ is the angle in degrees, r is the radius of the circle, and π is again approximately equal to 3.14.

Substituting the given values, we get

A = (100/360)π(3cm)²

A = 2.62 cm² (rounded to two decimal places)

Finally, we can find the area of the shaded region by subtracting the area of the sector from the area of the whole circle

Shaded area = Area of circle - Area of sector

Shaded area = 28.26 cm² - 2.62 cm²

Shaded area = 25.64 cm² (rounded to two decimal places)

Therefore, the area of the shaded region of the circle is approximately 25.64 square centimeters.

The actual price of the TV is $ 566.37. During a sale, it was sold at $ 502.21. 11.3282% decrease in the price of the TV.

First, we need to the difference in the price.

Let us call the actual price M.R.P and the value it was sold for as S.P

SO we have M.R.P = $ 566.37 and S,P = $ 502.21. THe difference D = M.R.P -S.P = $566.37-$502.21 = $64.16

To find the percent decrease will have to compare the difference with M.R.P and multiply it by a hundred so we get,

D% = (D/M.R.P)x 100 = 64.16/566.37 x100 = 11.3282 %.

Using polynomial division, it is found that the expression that represents the amount of candy sold each year per type at Cassandra's Candy Corner is:

\(2x^2 - 5x + 52\)

The amount of candy sold per type is given by the following division:

\(\frac{C(x)}{T(x)} = \frac{4x^3 + 10x^2 + 54x + 520}{2x + 10}\)

The denominator can be written as:

\(2x + 10 = 2(x + 5)\)

At the numerator, to see if we can simplify, we verify if x = -5 is a factor:

\(C(-5) = 4(-5)^3 + 10(-5)^2 + 54(-5) + 520 = 0\)

Since C(-5) = 0, it is a factor of the numerator, and thus, since the numerator is of the 3rd degree, it can be written as a 3 - 1 = 2nd degree polynomial multiplying x + 5:

\((ax^2 + bx + c)(x + 5) = 4x^3 + 10x^2 + 54x + 520\)

\(ax^3 + (5a + b)x^2 + (5b + c)x + 5c = 4x^3 + 10x^2 + 54x + 520\)

Equaling both sides:

\(a = 4\)

\(b = 10 - 5a = -10\)

\(5c = 520 \rightarrow c = 104\)

Thus:

\(C(x) = (4x^2 - 10x + 104)(x + 5)\)

And:

\(\frac{C(x)}{T(x)} = \frac{(4x^2 - 10x + 104)(x + 5)}{2(x + 5)} = 2x^2 - 5x + 52\)

Thus, the expression is:

3) 0.002 s: -45051.1 ft/sec

4) 0.001 s: -90051  ft/sec

Here, a ball is thrown with initial velocity of 46 ft/s.

The height of the ball in feet after t seconds is given by an equation,

 y = 21t - 12t²

Let us assume that P represents the average velocity.

The average velocity is given by formula,

P = [y(t₂) - y(t₁)]/[t₂ - t₁]

i) the average velocity for the time period beginning when t=3 and lasting  0.01 s

Here, t₂ = 3.01 s and  t₁ = 3 s

y(t₂) =  21(3.01) - 12(3.01)²

      = -45.5112

y(t₁) =  21(3) - 12(3)²

      = 45

y(t₂) - y(t₁) = -45.5112 - 45

                = -90.5112

So, P = -90.5112 / (0.01)

     P = -9051.12 ft/sec

ii) the average velocity for the time period beginning when t=3 and lasting  0.005 s

Here, t₂ = 3.005 s and  t₁ = 3 s

y(t₂) - y(t₁) = -45.5112 - 45

                = -90.2553

So, P = -90.2553 / (0.005)

     P = -18051.06 ft/sec

iii) the average velocity for the time period beginning when t=3 and lasting  0.002 s

Here, t₂ = 3.002 s and  t₁ = 3 s

y(t₂) - y(t₁) = -45.1021 - 45

                = -90.1021

So, P = -90.1021 / (0.002)

     P = -45051.1 ft/sec

iv) the average velocity for the time period beginning when t=3 and lasting  0.001 s

Here, t₂ = 3.001 s and  t₁ = 3 s

y(t₂) - y(t₁) = -45.051 - 45

                = -90.051

So, P = -90.051 / (0.001)

Answer:

A sample of 595 should be obtained.

Step-by-step explanation:

In a sample with a number n of people surveyed with a probability of a success of \(\pi\), and a confidence level of \(1-\alpha\), we have the following confidence interval of proportions.

\(\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}\)

In which

z is the zscore that has a pvalue of \(1 - \frac{\alpha}{2}\).

The margin of error is:

\(M = z\sqrt{\frac{\pi(1-\pi)}{n}}\)

Estimate of 0.55

This means that \(\pi = 0.55\)

95% confidence level

So \(\alpha = 0.05\), z is the value of Z that has a pvalue of \(1 - \frac{0.05}{2} = 0.975\), so \(Z = 1.96\).

What sample size should be obtained if she wishes the estimate to be within a margin of error of 0.04?

This is n for which M = 0.04. So

\(M = z\sqrt{\frac{\pi(1-\pi)}{n}}\)

\(0.04 = 1.96\sqrt{\frac{0.55*0.45}{n}}\)

\(0.04\sqrt{n} = 1.96\sqrt{0.55*0.45}\)

\(\sqrt{n} = \frac{1.96\sqrt{0.55*0.45}}{0.04}\)

\((\sqrt{n})^2 = (\frac{1.96\sqrt{0.55*0.45}}{0.04})^2\)

\(n = 594.2\)

Rounding up,

A sample of 595 should be obtained.

Answer: 1 3/5 divided by 3/8 is equal to 22/3 in simplest form.

Step-by-step explanation:

To express the answer to 1 3/5 divided by 3/8 in simplest form, we first need to convert the mixed number 1 3/5 to an improper fraction. To do this, we can multiply the whole number (1) by the denominator of the fraction (5) and add the numerator (3) to get:

1 * 5 + 3 = 8 + 3 = 11/5

We can then divide this fraction by 3/8 to get the final answer:

$\frac{11/5}{3/8}$

To divide fractions, we can multiply the numerator of the first fraction by the reciprocal of the second fraction:

$\frac{11/5}{3/8} = \frac{11/5}{3/8} \cdot \frac{8/8}{8/8} = \frac{11/5}{3/8} \cdot \frac{8}{3} = \frac{118}{53} = \frac{88}{15}$

Simplifying this fraction gives us:

$\frac{88}{15} = \frac{22}{3}$

Therefore, 1 3/5 divided by 3/8 is equal to 22/3 in simplest form.

The expressions In(√2+2) and - In(1-1/√2) are not equivalent.

To determine whether the two expressions are equivalent, we need to evaluate each expression and compare the results.

Expression 1: In(√2+2)

The square root of 2 (√2) is an irrational number approximately equal to 1.414.

Adding 2 to √2 gives us approximately 1.414 + 2 = 3.414.

Taking the natural logarithm (In) of 3.414 will give us the value of the expression.

Expression 2: - In(1-1/√2)

To evaluate - In(1-1/√2), we need to simplify it further.

Let's start by simplifying 1-1/√2:

1 - 1/√2 = (√2/√2) - (1/√2) = (√2 - 1)/√2

Taking the natural logarithm (In) of (√2 - 1)/√2 will give us the value of the expression.

To determine if the two expressions are equivalent, we would need to evaluate the numerical values of In(√2+2) and - In(1-1/√2). However, without the specific values of √2, we cannot compare the results directly.

Therefore, we cannot determine the equivalence of the two expressions without knowing the specific value of √2.
