Answer:

15200 cm²

Step-by-step explanation:

from inspection of the diagram, we can see that the prism comprises:

Triangle

Area of triangle = 1/2 x base x height

Given:

⇒ area = 1/2 x 60 x 40 = 1200 cm²

Base rectangle

Area of a rectangle = width x length

Given:

⇒ area = 60 x 80 = 4800 cm²

Side rectangle

Area of a rectangle = width x length

Given:

⇒ area = 50 x 80 = 4000 cm²

Total area = 2 triangles + base rectangle + 2 side rectangles

⇒ total area = (2 x 1200) + 4800 + (2 x 4000) = 15200 cm²

None of the provided options is correct. The simplified value of the expression [(23)4]2 is 65536.

To simplify the expression [(23)4]2, we start by evaluating the exponent inside the inner parentheses:

(23)4 = 23 * 23 * 23 * 23

This results in 256. Now, we substitute this value back into the expression:

[(23)4]2 = 2562

Squaring 256 gives us 65536. Therefore, the simplified value of the expression [(23)4]2 is 65536.

Answer:   the  answer  would  be  16 kids   walk  to  school  (10  girls  and  6  boys)

Step-by-step explanation:

Answer:

1) A) 64 tickets

  B) $11

2) A) 20 rides

Step-by-step explanation:

1) a) set y to 37 because they made 37 dollars

37 = 0.50x + 5

32 = 0.50x.........subtract 5 from both sides

64 = x..................divide both sides by 0.50 to get x by itself

b) set x to 12 because x is the amount of ride tickets they bought

y = 0.50(12)+ 5

y = 6 + 5............multiply 12 by 0.50

y=11......................add

2) a) set both equations equal to each other to see when they will be equal

0.50x + 5 = 0.75x

0.50x = 0.75x - 5..........subtract 5 from both sides

0.50x - 0.75x = - 5........subtract 0.75x from both sides

-0.25x = - 5......................combine like terms

x=20...................................divide both sides by -0.25 to isolate x

The probability that a randomly selected student scored between 70 and 84 is 0.8351

Probability is simply how likely something is to happen.

Whenever we’re unsure about the outcome of an event, we can talk about the probabilities of certain outcomes—how likely they are. The analysis of events governed by probability is called statistics.

given that:

mean = 80

standard deviation = 4

now we need to find the probability of students scored between 70 and 84

P(70<X<84) = P(X<84) - P(X>70)

                   = P(Z<(84-80)/4)-P(Z>(70-80)/4)

                   =P(Z<1) - P(Z>-2.5)

                   = 0.8413-0.0062

                   = 0.8351

The least number of years for the investment to triple is approximately 10 years.

To find the equivalent annual discount rate for a compound interest rate of i = 5%, we can use the formula:

Discount rate = (1 + i)^-1 - 1

Substituting the given interest rate, we have:

Discount rate = (1 + 0.05)^-1 - 1

Discount rate = 0.952381 - 1

Discount rate = -0.047619

The equivalent annual discount rate is approximately -0.047619.

To determine the number of years it takes for an investment to triple at an annual effective interest rate of i = 12%, we can use the compound interest formula:

Future value = Present value * (1 + i)^n

We want to find the least number of years (n) for the future value to be three times the present value. Let's set up the equation:

3 = 1 * (1 + 0.12)^n

Taking the logarithm of both sides, we get:

log(3) = n * log(1.12)

Solving for n, we have:

n = log(3) / log(1.12)

Using a calculator, we find that n ≈ 9.9 years.

Therefore, The least number of years for the investment to triple is approximately 10 years.

As per the question, All four students A, B, C, and D are loss-averse over money and have the same value function as below:v(x dollars)={√x     x ≥ 0   {-2√-x  x < 0They are also loss averse over mugs and have the same value function.

v(y mugs)={3y y ≥ 0
        {4y y < 0
Now, we have to find the values of a, b, c and d as below:
- Student A owns a mug and is willing to sell it for a price of a dollars or more. i.e v(a) = v(0) + v(a-A), where A is the initial endowment of A. According to the given function, v(0) = 0, v(a-A) = 3, and v(A) = 4.
So, a ≥ A+3/2
- Student B does not own a mug and is willing to pay up to b dollars for buying it. i.e v(B-b) = v(B) - v(0), where B is the initial endowment of B. According to the given function, v(0) = 0, v(B-b) = -4, and v(B) = -3.
So, b ≤ B+1/2
- Student C does not own a mug and is indifferent between getting a mug and getting c dollars. i.e v(c) = v(0) + v(c), where C is the initial endowment of C. According to the given function, v(0) = 0, v(c) = 3.
So, c = C/2
- Student D is indifferent between losing a mug and losing d dollars. i.e v(D-d) = v(D) - v(0), where D is the initial endowment of D. According to the given function, v(0) = 0, v(D-d) = -3.
So, d = D/2
2) In this case, value function for money changes to:v(x dollars)={√x     x ≥ 0
            {-√-x   x < 0
However, the value function for mugs remains the same:v(y mugs)={3y y ≥ 0
         {4y y < 0
Therefore, values for a, b, c, and d will remain the same as calculated in part (1).
3) In this case, students are not loss-averse. Value function for money:v(x dollars)={√x     x ≥ 0
            {-√-x   x < 0
Value function for mugs:v(y mugs)={3y y ≥ 0
The reference point is the status quo, i.e initial endowment. So,
- Student A owns a mug and is willing to sell it for a price of a dollars or more. The value of mug for A is 3 initially and he would sell it for 3 or more.
So, a ≥ A+3/2
- Student B does not own a mug and is willing to pay up to b dollars for buying it. The value of mug for B is 3 initially and he would buy it for 3 or less.
So, b ≤ B+3/2
- Student C does not own a mug and is indifferent between getting a mug and getting c dollars. The value of the mug for C is 3 initially.
So, c = 3
- Student D is indifferent between losing a mug and losing d dollars. The value of the mug for D is 3 initially.
So, d = 3
4) In this case, value function for money:v(x dollars)={√x     x ≥ 0
            {-√-x   x < 0
Value function for mugs: Mug will have a value of 4 for someone who owns it and 3 for someone who does not own it.
The reference point is the status quo, i.e initial endowment. So,
- Student A owns a mug and is willing to sell it for a price of a dollars or more. The value of mug for A is 4 initially and he would sell it for 4 or more.
So, a ≥ A+2
- Student B does not own a mug and is willing to pay up to b dollars for buying it. The value of mug for B is 3 initially and he would buy it for 3 or less.
So, b ≤ B+3/2
- Student C does not own a mug and is indifferent between getting a mug and getting c dollars. The value of the mug for C is 3 initially and he would like to buy it for 3.
So, c = 3
- Student D is indifferent between losing a mug and losing d dollars. The value of the mug for D is 3 initially.
So, d = 3.

Answer:

99 and 33

Step-by-step explanation:

let x and y be the 2 numbers, with x being the larger of the 2, then

x + y = 132 → (1)

x - y = 66 → (2)

add (1) and (2) term by term to eliminate y

(x + x) + (y - y) = 132 + 66

2x + 0 = 198

2x = 198 ( divide both sides by 2 )

x = 99

substitute x = 99 into (1) and solve for y

99 + y = 132 ( subtract 99 from both sides )

y = 33

the 2 numbers are 99 and 33

There is a 95% chance that the true mean of the population lies within the interval of [29.12, 40.88]. In other words, if we were to take many samples from the population and calculate their means, 95% of those means would fall within this interval.

Without additional information about the distribution of the data, it's difficult to provide an exact interval. However, we can use the standard normal distribution and the given values of "u" and "o" to approximate the interval.

Assuming a normal distribution, 95% of the data falls within 1.96 standard deviations of the mean. Therefore, the interval for the amount of data that appears within 95% of the mean would be:

u ± (1.96 * o)

= 35 ± (1.96 * 3)

= 35 ± 5.88

= [29.12, 40.88]

This means that there is a 95% chance that the true mean of the population lies within the interval of [29.12, 40.88]. In other words, if we were to take many samples from the population and calculate their means, 95% of those means would fall within this interval.

In this case, 5 is a whole number, integer (can be a fraction too) , and of course, is a rational number.

As of which options to choose, read the above sentence carefully :)

Answer:

Natural, Integer, Rational, Whole

Step-by-step explanation:

First, we should know the definition of the word choices.

1) Natural Numbers: We can also count it as 'counting numbers'. Natural numbers are numbers that are a whole excluding the number 0. Some examples are 1, 2, 3, 4, 5 ... and so on.

2) Irrationals: They are numbers that cannot be written in a fraction form. Some examples are \(\sqrt{2} , \sqrt{3} , \sqrt{4} , \pi ...\) etc.

3) Integers: They are a whole number that can be a negative, positive, or even a zero. Natural numbers are included in integers. Examples are -2, -1, 0, 1, 2, and so on.

4) Rationals: They are numbers that can be expressed in a fraction form, so it is the opposite of 'irrationals'. Examples are -1/2, 1/2, 2/4, 2/1 ... etc.

5) Whole Numbers: They are numbers that aren't a fraction. It can only be a positive number and a zero, so some examples would be 0, 1, 2, 3, 4, 5 ... and so on.

With these in mind, we can now solve the question. The number 5 is a natural, integer, rational, and a whole number.
