The length of arc EG is approximately 7.35 units.

To find the length of arc EG, we need to use the formula:

length of arc = (central angle/360°) × 2πr

where r is the radius of the circle and the central angle is in degrees.

We are given that m∠EFG = 58°, and EF = 6 units. Since EF is a chord of the circle, we can use the chord-chord angle theorem to find that m∠EGF = ½(180° - 58°) = 61°.

Now, we can use the Law of Cosines to find the length of GE:

GE² = EF² + FG² - 2(EF)(FG)cos(∠EGF)

GE² = 6² + FG² - 2(6)(FG)cos(61°)

Since FG = 2r (because it is the diameter of the circle),

GE² = 36 + (2r)² - 12r cos(61°)

We can simplify this to:

GE² = 4r² - 12r cos(61°) + 36

GE² = 4(r² - 3r cos(61°) + 9)

Now, we can use the formula for the length of the arc:

length of arc EG = (m∠EGF/360°) × 2πr

length of arc EG = (61/360) × 2πr

length of arc EG = (61/180) × πr

Substituting the expression for GE² in terms of r, we get:

length of arc EG = (61/180) × π √[4(r² - 3r cos(61°) + 9)]

We can now use a calculator to find the approximate value of the length of arc EG.

Rounded to the nearest hundredth, the length of arc EG is approximately 7.35 units.

(a) The probability that 6 out of 8 people selected at random are younger than 15 is approximately 0.2229.  (b) The probability that 2 out of 7 people selected at random are older than 65 is approximately 0.0058.

(a) To find the probability that 6 out of 8 people selected at random are younger than 15, we can use the binomial distribution formula:

P(X = 6) = (8 choose 6) x 0.48⁶ x (1 - 0.48)²

where (8 choose 6) = 8! / (6! x 2!) is the number of ways to choose 6 people out of 8.

Using a calculator, we get:

P(X = 6) ≈ 0.2229

Therefore, the probability that 6 out of 8 people selected at random are younger than 15 is approximately 0.2229.

(b) To find the probability that 2 out of 7 people selected at random are older than 65, we can again use the binomial distribution formula:

P(X = 2) = (7 choose 2) x 0.03² x (1 - 0.03)⁵

where (7 choose 2) = 7! / (2! x 5!) is the number of ways to choose 2 people out of 7.

we get: P(X = 2) ≈ 0.0058

This gives us a square with an area of 225 square units.

Step-by-step explanation:

To find the dimensions of the rectangle with the largest area for a given perimeter of 60, we need to use the formula for the perimeter of a rectangle, which is P = 2l + 2w, where P is the perimeter, l is the length, and w is the width.

In this case, we know that P = 60, so we can write:

60 = 2l + 2w

Simplifying this equation, we get:

30 = l + w

To find the largest area of the rectangle, we need to maximize the product of the length and the width, which is the formula for the area of a rectangle, A = lw.

We can solve for one variable in terms of the other using the equation above. For example, we can write:

w = 30 - l

Substituting this expression for w into the formula for the area, we get:

A = l(30 - l)

Expanding and simplifying this expression, we get:

A = 30l - l^2

This is a quadratic equation in l, which has a maximum value when l is halfway between the roots. We can find the roots using the quadratic formula:

l = (-b ± sqrt(b^2 - 4ac)) / 2a

In this case, a = -1, b = 30, and c = 0, so we get:

l = (-30 ± sqrt(30^2 - 4(-1)(0))) / 2(-1)

Simplifying, we get:

l = (-30 ± sqrt(900)) / -2

l = (-30 ± 30) / -2

So the roots are l = 0 and l = 30. We want the smaller value first, so we take l = 0 and find w = 30. This would give us a rectangle with zero area, so it is not a valid solution.

The other root is l = 30, which gives us w = 0. Again, this is not a valid solution because we need both dimensions to be positive.

Therefore, the dimensions of the rectangle with the largest area for a perimeter of 60 are:

l = 15 and w = 15

This gives us a square with an area of 225 square units.

The Taylor polynomial of degree n=3 at a=1 of the function f(x) = r is simply the polynomial T(r) = r.

To find the Taylor polynomial T(r) of degree n=3 at a=1 of the function f(x) = r, we first need to calculate the first four derivatives of f(x) with respect to x:

f(x) = r

f'(x) = 0

f''(x) = 0

f'''(x) = 0

f''''(x) = 0

Then, we evaluate these derivatives at x=a=1:

f(1) = r

f'(1) = 0

f''(1) = 0

f'''(1) = 0

f''''(1) = 0

Next, we can use the Taylor polynomial formula:

T(r) = f(a) + f'(a)(r-a) + (f''(a)/2!)(r-a)² + (f'''(a)/3!)(r-a)³ + ... + (fⁿ(a)/n!)(r-a)ⁿ

Since we are finding the Taylor polynomial of degree n=3, we only need to include the first four terms of this formula. Therefore, we get:

T(r) = f(1) + f'(1)(r-1) + (f''(1)/2!)(r-1)² + (f'''(1)/3!)(r-1)³

T(r) = r + 0(r-1) + 0/2!(r-1)² + 0/3!(r-1)³

The value of CDF Pr[28 < X ≤ 41] = F(41) - F(28) = 0.6 - 0.55 = 0.05.

Given that X is a discrete random variable that takes only positive integer values, we know the cumulative distribution function (CDF) values for certain values of X. We can use this information to find the value of k, which is missing.

First, we note that the CDF is a non-decreasing function, meaning that as X increases, F(X) cannot decrease. Therefore, we know that 0.55 ≤ k ≤ 0.6.

Next, we use the fact that the CDF is a step function, meaning that it increases by a finite amount at each integer value of X. Using this, we can find the difference in CDF values between adjacent values of X. For example, F(21) - F(13) = 0.49 - 0.45 = 0.04.

Using this method, we can find that F(47) - F(28) = 0.67 - 0.55 = 0.12 and F(54) - F(41) = 0.7 - k. We can then set these two expressions equal to each other and solve for k:

We can evaluate this integral using standard techniques, but it is quite involved and requires multiple integration by parts.

To find the x-coordinate of the center of mass of the given region, we need to evaluate the following triple integral:

∭E xρ(x, y, z) dV

where E is the region in the first octant bounded by the coordinate planes and the plane x + y + 2z = 10, ρ(x, y, z) = 8xyz is the density function, and dV is the volume element.

Since E is a bounded region, we can find its limits of integration as follows:

0 ≤ z ≤ (10 - x - y)/2

0 ≤ y ≤ 10 - x - 2z

0 ≤ x ≤ 10

To determine the sample size needed for a 95% confidence level when estimating the population proportion within a sampling error of ±0.02, we can use the formula for sample size in proportion estimation:
n = ([tex]Z^2[/tex] * p * (1-p)) / [tex]E^2[/tex]
where:
- n is the sample size
- Z is the Z-score corresponding to the desired confidence level (1.96 for 95% confidence)
- p is the historical population proportion (0.40)
- E is the desired sampling error (0.02)
Step 1: Identify the values for the formula
Z = 1.96 (for 95% confidence)
p = 0.40
E = 0.02
Step 2: Plug the values into the formula
n = ([tex]1.96^2[/tex] * 0.40 * (1 - 0.40)) / [tex]0.02^2[/tex]
Step 3: Calculate the sample size
n = (3.8416 * 0.40 * 0.60) / 0.0004
n = 0.9216 / 0.0004

b) The particle is moving to the left during time intervals.

c) The position function is x(t) = ∫³₀ sin(t) dt

d) At t = 3, the acceleration function is cos(3), which is negative. This means that the particle is slowing down at t = 3.

a. To find the total distance the particle traveled from time t = 0 to time t = 10, we need to integrate the absolute value of the velocity function over that time interval. This gives us the total distance traveled, regardless of the direction. So, the integral expression we need is:

∫₀¹⁰ |sin(t)| dt

b. To determine when the particle is moving to the left, we need to look at the velocity function. Recall that when the velocity is negative, the particle is moving to the left. In this case, the sine function is negative for values of t between π and 2π, and between 3π and 4π.

c. To find the position of the particle at time t = 3, we need to integrate the velocity function from t = 0 to t = 3. This gives us the displacement of the particle from its initial position at t = 0. So, the position function is:

x(t) = ∫³₀ sin(t) dt

d. Finally, we need to find the acceleration of the particle at t = 3 and determine whether the particle is speeding up, slowing down, or neither. Recall that acceleration is the derivative of velocity. So, we can find the acceleration function by taking the derivative of the velocity function:

What is a quadratic equation?

A quadratic equation is a second-degree polynomial equation of the form ax²+ bx + c = 0 where a, b, and c are constants, and x is the variable.

Since h(t) is a quadratic function, it can be written in the form:

h(t) = at² + bt + c

where a, b, and c are constants to be determined. We can use the given information to set up a system of equations:

h(0) = 0 → c = 0

h(2) = 65 → 4a + 2b = 65

h(4) = 0 → 16a + 4b = 0

Solving this system of equations, we get:

a = -8.125

b = 32.5

Therefore, the quadratic function that models the height of the rocket from the ground at time t is:

h(t) = -8.125t² + 32.5t

To find the maximum value of the graph of this function, we can use the formula:

t = -b/2a

In this case, substituting the values of a and b, we get:

t = -32.5/(2*(-8.125)) = 2

Therefore, the maximum value of the graph of the function occurs at t = 2 seconds. To find the maximum height, we can substitute t = 2 into the function:

h(2) = -8.125(2)² + 32.5(2) = 52.5

There are five black dices, which are the numbers 1, 3, 6, 8, and 9. There are three other numbers that are at least 5, which are 5, 10, and 11. The number 10 appears in both lists, so we must subtract it once from the total count.

Therefore, the total number of outcomes that satisfy the condition of being black or at least 5 is:

Number of black or at least 5 outcomes = 5 + 3 - 1 = 7

Since there are 12 possible outcomes, the probability of rolling a black or at least 5 number is:

P(black OR at least 5) = 7/12

Sanji scored 169 more points in the third round than in the first round.

Sanji's total score in the video game can be found by adding up the scores from each round. We know that Sanji scored 125125 points in the first round and 263263 points in the second round. Therefore, his total score before the third round was:

Total score before third round = 125 + 263 = 388

We also know that Sanji's total score after the third round was 557557 points. So we can set up an equation:

Total score = Score in first round + Score in second round + Score in third round

Or, substituting the scores we know:

557 = 125 + 263 + Score in third round

Simplifying:

Score in third round = 557 - 125 - 263

Score in third round = 169

Therefore, Sanji scored 169 more points in the third round than in the first round.

The given statement " The normal curve is symmetric about its​ mean, u" is true because it is equally distributed on both the sides of the mean.

The normal curve is always symmetric about the line representing its mean, u.

This means that the curve is equally distributed on both sides of the line representing the mean.

And the area under the curve to the left of the mean is equal to the area under the curve to the right of the mean.

This is a defining characteristic of the normal distribution.

Which is widely used in statistics due to its many useful properties.

Therefore, the normal curve is symmetric which is about its mean is a true statement.
