Of the given four estimators, the one that shows the most bias is Mean = 20, SE = 1. Hence, Mean = 20, SE = 1 is the accurate choice.

The estimator with the highest value (Mean = 20) compared to the population parameter (15) is the most biased. The lower the standard error (SE = 1), the more confident the estimate, but if the estimate is far from the population parameter, it is considered biased.

In this case, the Mean = 20 estimator is the most biased because it has the greatest difference from the population parameter and the lowest standard error, indicating a high level of confidence in the estimate despite it being significantly different from the actual population parameter.

The contents of r0 will be 0x20000851, which is the first byte of the word stored at address 0x20000850.

The TI TM4C123 is a little-endian processor, meaning that it stores data in the memory in reverse order. This means that the first byte of a word will be stored at the lower address, and the last byte at the higher address.

In this example, register r1 contains the address 0x20000850. When we execute the ldr r0, [r1] instruction, the processor will read the value stored in memory at address 0x20000850 and store it in register r0.

Since this is a little-endian processor, the value stored in memory at address 0x20000850 will be the last byte of the word, and the value stored in memory at address 0x20000851 will be the first byte of the word.

This means that the contents of r0 will be 0x20000851, which is the first byte of the word stored at address 0x20000850.

What exactly is integration?

The process of computing an integral is known as integration. Mathematicians utilise integrals to compute a variety of useful quantities such as areas, volumes, displacement, and so on. When we talk about integrals, we usually imply definite integrals. Antiderivatives are represented by indefinite integrals. Integration, along with differentiation, is one of the two major calculus concepts in mathematics (which measure the rate of change of any function with respect to its variables).

Integral Fundamental

A definite integral is one that has both upper and lower bounds. For X to lie, only a true line may be utilised. The Definite Integral is also known as a Riemann Integral.

From a to b, use ∫f(x)dx

indefinite integral

Integrals are defined without upper and lower limits. It looks like this:

A indefinite Integral is written as:

∫f(x)dx = F(x) + C

Where C might be any constant and the function f(x) is referred to as the integrand.

Now,

Answer:

880 feet; 0.166666666 miles or ⅙ of a mile

Step-by-step explanation:

First convert miles to feet so 1 mile is 5280 feet.

Now divide it by 2 because we're working with half a mile per 3 minutes.

Now we know that Kelly can run 2640 feet every 3 minutes. Divide that by three to get her pace for every minute and we know that she runs 880feet per minute. In miles that would be 0.166 or ⅙ of a mile

Step-by-step explanation:

the ratio is

1/2 mile per 3 minutes

= 1/2 / 3

now, we need to keep the value of that ratio unchanged but still transform the ratio (= a fraction) so that we get as ultimate denominator 1 instead of 3 (how far did he run in 1 minute).

what do we need to do to transform 3 to 1 ?

we need to divide by 3.

and because we have to keep the ratio value, we have to devide also the numerator by 3 :

1/2 / 3 × 1/3 / 1/3 = (1/2 × 1/3) / (3 × 1/3) = 1/6 / 1

so, we can read from the result directly :

when running with the same pace (ratio) for 1 minute, he will run 1/6 mile.

The surface area of the entire figure is 1764 ft².

A rectangular prism is a three-dimensional shape that has six faces, where each face is a rectangle. It is also sometimes referred to as a rectangular cuboid.

A rectangular prism has eight vertices (corners), 12 edges, and six faces. The opposite faces of a rectangular prism are parallel and congruent, and the angles formed between adjacent faces are all right angles (90 degrees).

The volume of a rectangular prism can be calculated by multiplying the length, width, and height of the prism. The formula for the volume of a rectangular prism is given by V = l x w x h, where V is the volume, l is the length, w is the width, and h is the height of the prism.

We can begin by finding the dimensions of the rectangular prism and the cuboid. Since the side of the rectangular prism is 9 ft, it must be the height of the entire figure. We can find the dimensions of the cuboid by subtracting the height of the rectangular prism from the height of the entire figure:

height of cuboid = 19.8 ft - 9 ft = 10.8 ft

width of cuboid = 15 ft

length of cuboid = 12 ft

Now we can find the surface area of the entire figure by adding the surface areas of the rectangular prism and the cuboid. The surface area of a rectangular prism is given by:

2lw + 2lh + 2wh

where l, w, and h are the length, width, and height of the prism, respectively. Substituting in the values we have:

surface area of rectangular prism = 2(9)(9) + 2(9)(19.8 - 9) + 2(9)(15) = 486 + 162 + 270 = 918 ft²

The surface area of a cuboid is given by:

2lw + 2lh + 2wh

where l, w, and h are the length, width, and height of the cuboid, respectively. Substituting in the values we have:

surface area of cuboid = 2(15)(9) + 2(12)(9) + 2(15)(12) = 270 + 216 + 360 = 846 ft²

Therefore, the surface area of the entire figure is:

surface area = surface area of rectangular prism + surface area of cuboid = 918 + 846 = 1764 ft²

Answer:

Step-by-step explanation:

To calculate the simple interest earned on an investment of $9710 at a semiannual rate of 3.6% for 4 years, we need to use the formula:

I = Prt

where I is the interest, P is the principal (initial investment), r is the interest rate (as a decimal), and t is the time (in years).

In this case, the principal is $9710, the interest rate is 3.6% per year, or 0.036/2 = 0.018 per 6-month period (since the interest is compounded semiannually), and the time is 4 years, or 8 periods of 6 months each.

Plugging in these values, we get:

I = $9710 x 0.018 x 8 = $1392.24

Therefore, the simple interest earned on the investment is $1392.24. Rounding to the nearest cent, the answer is $1392.24.

Answer:

33 miles per hour

Step-by-step explanation:

To find the speed of the car in miles per hour, we need to divide the number of miles traveled by the time in hours. We can convert minutes to hours by dividing by 60. So, the time in hours is 45 minutes / 60 minutes/hour = 0.75 hours. Then, we can divide the distance traveled by the time to find the speed:

25 miles / 0.75 hours = 33.33 miles per hour

Rounding to the nearest whole number, the speed of the car was 33 miles per hour.

The area of shaded region would be 15.7 in² which is a difference between the area of the circle and area of the triangle.

The entire space filled by a triangle's three sides in a two-dimensional plane is defined as its area. The fundamental formula for calculating the area of a triangle is A = 1/2 b h.

We know that;

The area of an equilateral triangle = (√3/4) a²

Here, a = 3

Hence, The area of the given triangle = (√3/4) × 3²

The area of the given triangle = 0.43 × 9 = 3.9 in²

And, The area of the circle = π (d/2)²

Here d = 5

The area of the circle = π (5/2)² = 19.63 in²

Thus, The area of shaded region = area of the circle - area of the triangle

The area of shaded region = 19.63 - 3.9 = 15.7 in²

Step-by-step explanation:

The probability of pulling out each type of coin at random can be found by dividing the number of coins of that type by the total number of coins in the bag. Let's assume the bag contains n quarters, m dimes, k nickels, and p pennies. The total number of coins in the bag would be n + m + k + p.

The probability of pulling out a quarter would be:

P(quarter) = n / (n + m + k + p)

The probability of pulling out a dime would be:

P(dime) = m / (n + m + k + p)

The probability of pulling out a nickel would be:

P(nickel) = k / (n + m + k + p)

And the probability of pulling out a penny would be:

P(penny) = p / (n + m + k + p)

It's important to note that the sum of the probabilities of all the possible outcomes must equal 1:

P(quarter) + P(dime) + P(nickel) + P(penny) = 1

desired cases / totally possible cases

when pulling one card out of 52 cards, the totally possible cases for the result are 52.

now, all we need to do is "counting" or calculating the desired cases for each problem.

a 3 or a heart is pulled.

it is important to really read this carefully : 3 OR a heart. not 3 and a heart (that would ask for the probability to pull the 3 of hearts card, as no other card would satisfy the criteria).

we have 13 cards of heart.

and we have 4 cards of the value 3. but one of them is already included in the 13 cards of heart.

so, we need to add only 3 to these 13 and get 16 desired cards.

the probability is therefore

16/52 = 4/13 = 0.307692308... ≈ 0.308

a face card OR a club is pulled.

face cards are Jack, Queen and King (the ones with faces on the cards). so, 3 per suit, 4 suits = 12 cards.

we have 13 cards of club.

3 of these cards are already in the group of face cards, so we need to add only 10 to to this group for the desired cases. and the probability is

22/52 = 11/26 = 0.423076923... ≈ 0.423

a face card AND a heart is pulled.

we have 13 cards of heart.

Angular velocity is the time rate at which an object rotates or revolves about an axis. Angular velocity is represented by the Greek letter omega (ω) It is measured in angle per unit time; hence, the SI unit of angular velocity is radians per second.

w = tetha/t

1 revolution = 360° = 2π

1 minutes = 60s

w = 12× 2π/60

w = 24×3.14/60

w = 1.26 radian/second

Step-by-step explanation:

Given that bags of peanuts cost $0.93 each, booth rental costs $220 for the week, and your selling price is $2.90 per bag, you want expressions for cost, revenue, and profit, and you want these values when sales are 320 bags of peanuts for the week.

The total cost is the sum of fixed and variable costs. The fixed cost is the cost of booth rental, $220. The variable cost is the per-bag cost of peanuts, multiplied by the number of bags.

  total cost = 0.93n +220

The revenue is the selling price, multiplied by the number of bags sold:

  revenue = 2.90n

Profit is the difference between revenue and cost.

  profit = revenue -cost

  profit = (2.90n) -(0.93n +220)

  profit = 1.97n -220

  cost = 0.93·320 +220 = 297.60 +220 = $517.60 . . . total costs

  revenue = 2.90·320 = $928.00 . . . revenue

  profit = 1.97·320 -220 = 630.40 -220 = $410.40 . . . profit
