The Gallup organization recently conducted a survey of 1,015 randomly selected U.S. adults about "Black Friday" shopping. They asked the following question: "As you know, the Friday after Thanksgiving is one of the biggest shopping days of the year. Looking ahead, do you personally plan on shopping on the Friday after Thanksgiving, or not?" Of the 515 men who responded, 16% said "Yes." Of the 500 women who responded, 20% said "Yes." Construct a 95% confidence interval for the difference between the proportion of men and women who planned to shop on the Friday after Thanksgiving. Use three decimal places when computing the margin of error. -0.103 to 0.023 0 -0.102 to 0.022 0 -0.087 to 0.007 0 -0.080 to 0.000

An equation for revenue (r) as a function of (p) is R = 1380p - 10p²,

and R(25) = 28250.

Given that;

The cost of tickets for a specific series of concerts is set by a concert venue. The sales team discovers that 1,000 people on average attend concerts with tickets costing $38. The average attendance increases by 50 persons for every $5 decrease in price. Then,

Let 'T' be the number of times the price is decreased.

So, price;

     p = 38 – 5x

     x = (38 - p) / 5

And as per the given condition attendance;

a = 1000 + 50x

So, the Revenue is;

To develop an equation for revenue (r) as a function of p, the price of tickets;

R = p * a

R= p * (1000 + 50x)

But,  x = (38 - p) / 5

Then,

R = P * (1000 + 50(38 - p)/5)

  = p * (1000 + 380 - 10p)

  = p * (1380 – 10p)

  = 1380p - 10p²  → (I)

To get R(25) from (I);

R(25) = 1380(25) - 10(25)²

         = 34500 - 6250

         = 28250

Hence, an equation for revenue (r) as a function of (p) is R = 1380p - 10p²,

and R(25) = 28250.

There will be 38 elk in the herd one year from now, rounded to a whole number.

To solve the given problem, we must use the formula for exponential growth or decay.

We'll use the following formula:

N = N0ert

Where,N is the final population;

N0 is the initial population;

r is the intrinsic growth rate;

e is the base of the natural logarithm; and

t is the time (in years).

According to the problem, the carrying capacity for a population of elk is 52, and there are currently 33 elk in the population.

The intrinsic growth rate of elk is 0.2 per year. We need to find out how many elk will be in the herd one year from now, rounded to a whole number.

Using the formula above, we can write:

N = 33e0.2 × 1= 37.98 ≈ 38

Therefore, there will be 38 elk in the herd one year from now, rounded to a whole number. Answer: 38.

Answer:

18 students.

Step-by-step explanation:

Total amount is 100

Take 68 and add to 60 to get 128.

Subtract from both numbers until you get to 50.

68 needs 18 subtracted to get to 50.

60 needs 10 to get to 50.

18 plus 10 is 28, which is the excess.

Here, 18 people like only football.

Answer:

i think 40

if 68 =likes foot ball

&60=likes volley ball

here there are available the students that likes both because 68+60=128 but the students are 100 so the students that likes both are 128-100=28

threfore the students that like only football are 40

cause the 68 likes football & the28 likes only football

so to know how many students likek foot ball evaluate like this (68-28=40)

It Will take approximately 1.99 minutes for the element to decay to 80 grams.

To solve this problem, you can use the formula for exponential decay: y = a * b^x

Where "y" is the final amount of the substance, "a" is the initial amount of the substance, "b" is the decay constant (in this case, b = 0.5 since the half-life of element x is 11 minutes), and "x" is the time in which the decay occurs.

In this case, we are trying to find the value of "x" (the time in which the decay occurs) given the values of "y" (80 grams) and "a" (300 grams).

Substituting these values into the formula, we get:

80 = 300 * 0.5^x

To solve for x, we can divide both sides by 300 and take the logarithm of both sides: log(80/300) = log(0.5^x)

-1.386 = x * log(0.5)

-1.386 = x * -0.693

x = 1.99

This tells us that it would take approximately 1.99 minutes for the element to decay to 80 grams. Rounding to the nearest tenth of a minute, this is approximately 2.0 minutes.

Therefore, it would take approximately 1.99 minutes for the element to decay to 80 grams.

33 1/3%=100/3%

A percent as a decimal is percentage divided by 100

(100/3)/100=1/3

Since 1/3 of a number is 24 we can say

n/3=24

n=72

So 24 is 33 1/3% of 72

According to the question The local sidereal time (LST) at noon on March 21st is approximately 12:00 (option c).

To determine the LST, we need to consider the rotation of the Earth and its relation to the stars. LST is based on the apparent motion of the vernal equinox, which completes a full cycle in approximately 24 hours.

Since noon is halfway through the day, we can estimate that the LST at noon would be approximately half of 24 hours, which is 12:00. This assumes that we are considering a location where the local time is synchronized with the standard time zone and there are no factors like daylight saving time or variations in the location's longitude that can affect the LST calculation.

Therefore, the correct answer is option c) 12:00 local sidereal time.

The number 55 represents the speed of the car in miles per hour.

In the expression 245 - 55T, the number 55 represents the speed of the car in miles per hour.

To see why, consider the formula for distance, which is:

distance = speed x time

In this case, the distance is given by 245 - 55T, where T is the time in hours that the family has been driving. We can rearrange this formula to get:

speed = distance / time

Substituting the expression for distance, we get:

speed = (245 - 55T) / T

Simplifying this expression, we get:

speed = 245/T - 55

This shows that the speed of the car is given by 245 divided by the time in hours plus a constant of -55. Therefore, the number 55 represents the speed of the car in miles per hour.

The value of slant height of cone is,

⇒ l = 4.2 feet

We have to given that,

The slant height of a cone with a volume of approximately 28.2 ft and a height of 2 ft.

Now, We know that,

Volume of cone is,

⇒ V = πr²h / 3

Here, We have;

⇒ V = 28.2 feet

⇒ h = 2 feet

Substitute all the values, we get;

⇒ V = πr²h / 3

⇒ 28.2 = 3.14 × r² × 2 / 3

⇒ 28.2 × 3 = 6.28r²

⇒ 84.6 = 6.28 × r²

⇒ 13.5 = r²

⇒ r = √13.5

⇒ r = 3.7 feet

Since, We know that,

⇒ l² = h² + r²

Where, 'l' is slant height and 'r' is radius.

⇒ l² = 2² + 3.7²

⇒ l² = 4 + 13.5

⇒ l² = 17.5

⇒ l = √17.5

⇒ l = 4.2 feet

Thus, The value of slant height of cone is,

Answer:

x = -4

y = -3

Step-by-step explanation:

-5y + 3x = 3

-8y + 9x = -12​

Time the first equation by -3

15y - 9x = -9

-8y + 9x = -12

7y = -21

y = -3

Now put -3 in for y and solve for x

-5(-3) + 3x = 3

15 + 3x = 3

3x = -12

x = -4

Let's Check

-5(-3) + 3(-4) = 3

15 - 12 = 3

3 = 3

First half (17,18,19,20)=18.5

Second half (21,24,25,27) = 24.5

Step-by-step explanation:

eliminate numbers on both sides till you get to the middle if there is an even number add up the two numbers in the middle and divide them by 2

For example, In the whole thing, you are left with 20 and 21 so

20+21 =41/2= 20.5

For example, In the first part, you are left with 18 and 19 so

18+19 =37/2= 18.5

For example, In the first part, you are left with 24 and 25 so

24+25 =49/2= 24.5
