To calculate the standard deviation of the sampling distribution of p-hat, the answer will be 59 students.

By calculating,

600/10=60 and 59 students which is less than 10% of the population.

A sampling distribution, also known as a finite-sample distribution, in statistics is the probability distribution of a given random-sample-based statistic. The sampling distribution is the probability distribution of the values that the statistic takes on if an arbitrarily large number of samples, each involving multiple observations (data points), were used separately to compute one value of a statistic (such as, for example, the sample mean or sample variance) for each sample. Although only one sample is frequently observed, the theoretical sampling distribution can be determined.

Because they offer a significant simplification before drawing conclusions using statistics, sampling distributions are crucial in the field. They enable analytical decisions to be made based on the probability distribution of a statistic rather than the combined probability distribution of all the individual sample values

The expression for area of the rectangles are obtained as x² + 10x + 21 and  x² - 9x + 8 respectively. The correct options for both parts are (C) and (B) respectively.

An algebraic expression can be obtained by doing mathematical operations on the variable and constant terms.

The variable part of an algebraic expression can never be added or subtracted from the constant part.

The dimension of both the rectangles are given as,

First rectangle : (x + 3) and (x + 7)

Second rectangle : (x - 1) and (x - 8)

Since, the area of a rectangle is product of its dimensions.

It can be obtained as,

Area of first rectangle is given as,

⇒ (x + 3) × (x + 7)

⇒ x² + 10x + 21

Area of second rectangle is given as,

⇒ (x - 1) × (x - 8)

⇒ x² - 9x + 8

Hence, the area of both the rectangles are obtained as  x² + 10x + 21 and  x² - 9x + 8 respectively.

The value of the iterated integral, evaluated by converting to polar coordinates, is √2/3.

What is integral?
An integral is a mathematical operation that calculates the area under a curve or the accumulation of a quantity over an interval. It is used to find the total value or the net change of a function and has applications in areas such as calculus, physics, and economics.

To convert the given integral to polar coordinates, we make the following substitutions:

x = rcosθ

y = rsinθ

dx dy = r dr dθ

The limits of integration also need to be adjusted accordingly. For the innermost integral, the limits become:

0 ≤ y ≤ √(x² - y²)

0 ≤ y ≤ √(r²cos²θ - r²sin²θ)

0 ≤ y ≤ r√(cos²θ - sin²θ)

0 ≤ y ≤ r√(cos²θ - (1 - cos²θ)) [Using the identity sin²θ = 1 - cos²θ]

0 ≤ y ≤ r√(2cos²θ - 1)

For the middle integral, the limits become:

0 ≤ x ≤ √x² + y²

0 ≤ x ≤ √(r²cos²θ + r²sin²θ)

0 ≤ x ≤ r

Finally, for the outermost integral, the limits are:

0 ≤ r ≤ √2

0 ≤ θ ≤ π/2

Now we can express the integral in polar coordinates:

∫ √2 0 ∫ x 0 √x²+y² dy dx = ∫ π/2 0 ∫ r 0 r√(2cos²θ - 1) r dr dθ

Simplifying the expression and integrating:

∫ π/2 0 ∫ r 0 r√(2cos²θ - 1) r dr dθ = ∫ π/2 0 ∫ r 0 r²√(2cos²θ - 1) dr dθ

Integrating the inner integral with respect to r:

∫ π/2 0 [1/3 r³√(2cos²θ - 1)] evaluated from 0 to r dθ

= ∫ π/2 0 (1/3 r³√(2cos²θ - 1) - 0) dθ

= ∫ π/2 0 (1/3 r³√(2cos²θ - 1)) dθ

Integrating the outer integral with respect to θ:

[1/3 r³√(2cos²θ - 1)] evaluated from π/2 to 0

= [1/3 r³√(2cos²(0) - 1)] - [1/3 r³√(2cos²(π/2) - 1)]

= [1/3 r³√(2 - 1)] - [1/3 r³√(0 - 1)]

= [1/3 r³] - [1/3 r³(-1)]

= [1/3 r³] + [1/3 r³]

= 2/3 r³

Now, substitute back r = √2:

2/3 (√2)³ = 2/3 (2√2)

= √2/3

Hence, the value of the given iterated integral, evaluated by converting to polar coordinates, is √2/3.

Answer:56

Step-by-step explanation:

I think cuz I multiplied 7x2x4

The current yield on this bond is 6.49%.

A bond's yearly interest payment, market price, and par value must be known in order to determine the bond's current yield.

In this question, we are given that the bond pays an annual interest of $60, has a par value of $1,000, and is selling at a $75.25 discount from par value.

So, the market price of the bond is the par value minus the discount, which is \($ 1,000\) - \($75.25\) \(= $924.75.\)

To calculate the current yield, we use the formula:

Current Yield \(=\) (Annual Interest Payment / Current Market Price) x 100%

With our current values substituted, we obtain:

Current Yield \(= ($60 / $924.75) × 100%\)

Current Yield \(= 0.0649 × 100%\)

Current Yield \(= 6.49%\)%

Therefore, (B) 6.49% is the right response.

Answer:

Answer:

It's 4

Step-by-step explanation:

The total distance traveled, d, can be calculated by summing the distances covered during each phase of the journey.

First, we calculate the distance covered during the first phase of the journey, where the speed is v₁ = 65.6 mph for t₁ = 2.84 hours:

Distance₁ = v₁ * t₁

Since the speed is given in miles per hour, we need to convert the time to hours:

t₁ = 2.84 hours

Distance₁ = 65.6 mph * 2.84 hours

Next, we calculate the distance covered during the second phase, where the speed is v₂ = 56.2 mph for t₂ = 0.80 hours:

Distance₂ = v₂ * t₂

Distance₂ = 56.2 mph * 0.80 hours

Finally, we sum the distances covered in both phases to find the total distance:

d = Distance₁ + Distance₂

Now, let's calculate the average speed, v, for the entire journey. Average speed is defined as total distance divided by total time:

Total time = t₁ + t_stop + t₂

Note that the stoppage time, t_stop, needs to be converted from minutes to hours:

t_stop = 33.6 min / 60

Total time = 2.84 hours + t_stop + 0.80 hours

Average speed, v, is then:

v= d / (t₁ + t_stop + t₂)

The total distance, d, traveled is calculated by summing the distances covered in each phase of the journey. The average speed, v, is obtained by dividing the total distance by the total time taken for the entire journey.

To find the total distance traveled, we need to calculate the distances covered in each phase separately and then sum them up. In the first phase, the speed is given as 65.6 mph and the time is 2.84 hours. To find the distance covered, we multiply the speed by the time:

Distance₁ = 65.6 mph * 2.84 hours

In the second phase, the speed is 56.2 mph and the time is 0.80 hours:

Distance₂ = 56.2 mph * 0.80 hours

Now, we sum the distances covered in both phases:

d = Distance₁ + Distance₂

To find the average speed, we need to calculate the total time taken for the entire journey. This includes the time spent in the stoppage. The stoppage time is given as 33.6 minutes, so we need to convert it to hours by dividing by 60:

t_stop = 33.6 min / 60

The total time taken is the sum of the time in the first phase, stoppage time, and the time in the second phase:

Total time = t₁ + t_stop + t₂

Finally, we can calculate the average speed by dividing the total distance by the total time:

v= d / (t₁ + t_stop + t₂)

By calculating the above expressions, we can determine the total distance traveled and the average speed for the journey.

Answer/Step-by-step explanation:

Given:

m<12 = 121°

m<6 = 75°

a. m<1 = m<6 (vertical angles)

m<1 = 75° (substitution)

b. m<12 = m<1 + m2 (alternate exterior angles)

121° = 75° + m<2 (substitution)

121° - 75° = m<2 (subtraction property of equality)

46° = m<2

m<2 = 46°

c. m<1 + m<2 + m<3 = 180° (angles on a straight line)

75° + 46° + m<3 = 180° (substitution)

121° + m<3 = 180°

m<3 = 180° - 121° (subtraction property of equality)

m<3 = 59°

d. m<4 = m<3 (vertical angles)

m<4 = 59° (substitution)

e. m<5 + m<4 + m<6 = 180° (angles on a straight line)

m<5 + 59° + 75° = 180° (substitution)

m<5 + 134° = 180°

m<5 = 180° - 134° (Subtraction property of equality)

m<5 = 46°

f. m<7 = m<12 (vertical angles)

m<7 = 121° (substitution)

g. m<8 = m<4 (vertical angles)

m<8 = 59° (substitution)

h. m<9 = m<6 (Alternate Interior Angles)

m<9 = 75° (substitution)

i. m<10 + m<9 = 180° (Linear Pair)

m<10 + 75° = 180° (substitution)

m<10 = 180° - 75° (Subtraction property of equality)

m<10 = 105°

j. m<11 = m<8 (vertical angles)

m<11 = 59° (substitution)

k. m<13 = m<10 (vertical angles)

m<13 = 105° (substitution)

l. m<14 = m<9 (vertical angles)

m<14 = 75° (substitution)

Answer:

Age of the spear head = 6349 years.

Step-by-step explanation:

Expression to be used to calculate the age of the spear head,

\(N_t=N_0e^{-kt}\)

Here, \(N_t\) = Final amount of C-14

\(N_0\) = Initial amount

\(k\) = 0.0001

\(t\) = Time in years

If \(N_t\) = 53% of \(N_0\) = \(N_0\times (0.53)\)

\(0.53N_0=N_0e^{-0.0001\times t}\)

\(0.53=e^{-0.0001t}\)

\(\text{ln}(0.53)=\text{ln}(e^{-0.0001t})\)

\(-0.634878=(-0.0001)t\)

\(t=6348.78\) years

\(t\) ≈ \(6349\) years

Therefore, age of the spear head = 6349 years.
