Answer: y = -12x + 63

Step-by-step explanation:

The slope-intercept form of a linear equation is y = mx + b, where m is the slope and b is the y-intercept. We are given the slope of the line, which is -12, and a point that the line passes through, which is (6,-9).

Using the point-slope form of a linear equation, we have:

y - (-9) = -12(x - 6)

Simplifying this equation, we get:

y + 9 = -12x + 72

Subtracting 9 from both sides, we get:

y = -12x + 63

Therefore, the equation of the line in slope-intercept form is y = -12x + 63.

The function that represents the estimated population after t years with an annual rate of decrease of 0.25% is y = [tex]358,000(0.9975)^{t}[/tex]. So  correct option is D) .

Annual rate can also be used to describe growth rates or changes in other types of measurements, such as population growth or inflation. For example, if the population of a city grows by 2% per year, the annual rate of population growth is 2%.

It is important to note that when annual rates are used to describe financial products or investments, they may be compounded over time. Compounding refers to the process of earning interest on interest, which can significantly increase the total amount of interest owed or earned over time. Therefore, it is important to carefully consider the effects of compounding when evaluating financial products or investments.

The function that represents the estimated population after t years with an annual rate of decrease of 0.25% is:

y = [tex]358,000(0.9975)^{t}[/tex]

We can approach this problem using the following steps:

Calculate the exchange rate after factoring in the agency commission. Since the agency commission is 1.5%, the effective exchange rate will be:

Effective exchange rate = Exchange rate - (Exchange rate * Commission rate)

= 30.075199 - (30.075199 * 0.015)

= 29.6185968

Multiply the amount of South African rands by the effective exchange rate to get the amount in British pounds.

Amount in pounds = Amount in rands / Exchange rate

So, for an amount of 2100 South African rands, the calculation would be:

Amount in pounds = 2100 / 29.6185968

= 70.815 pounds (rounded to three decimal places)

Therefore, Brian will get 70.815 pounds for 2100 South African rands after factoring in the agency commission.

One way to approach this problem without using a calculator is to group the numbers by their place value (i.e., thousands, hundreds, tens, and ones), and then add them together.

For example,

For thousands:

User A has 3 thousands,

User B has 4 thousands,

User C has 2 thousands,

User E has 7 thousands.

There are no thousands for User D.

So the total number of thousands is 3+4+2+7 = 16 thousands.

For hundreds:

User A has 550 hundreds (since 3550 = 3 x 1000 + 550),

User B has 0 hundreds (since 4000 is a multiple of 1000),

User C has 450 hundreds (since 2450 = 2 x 1000 + 450),

User D has 10 hundreds,

User E has 0 hundreds (since 7000 is a multiple of 1000).

So the total number of hundreds is 550+0+450+10+0 = 1010 hundreds.

For tens and ones:

Since all the numbers are in thousands or hundreds, there are no tens or ones to add.

Therefore, the total amount of data stored on the server is:

The probability of at least 2 people having the same birthday in a group of 23 people is 0.5073.

The probability of at least 2 people having the same birthday in a group of 23 people can be calculated using the rule for complements. The complement of this event is that all 23 people have different birthdays. We can calculate the probability of this event and then subtract it from 1 to find the probability of at least 2 people having the same birthday.

The probability of the first person having a different birthday from the others is 1. The probability of the second person having a different birthday from the first is 364/365, since there are 364 days left that are not the first person's birthday. The probability of the third person having a different birthday from the first two is 363/365, and so on.

The probability of all 23 people having different birthdays is:

1 * (364/365) * (363/365) * ... * (343/365)

This simplifies to:

364! / (36522 * 341!)

Using a calculator, we find that this is approximately 0.4927.

Therefore, the probability of at least 2 people having the same birthday is:

1 - 0.4927 = 0.5073

So, the probability of at least 2 people having the same birthday in a group of 23 people is 0.5073.

In a group of 23 persons, the probability that at least two of them share the same birthday is around 0.5073, or 50.73%.

The probability that at least 2 people in a group of 23 have the same birthday, can be calculated by using the rule for compliments. First, we can calculate the probability that no two people share a birthday in a group of  23.

The first individual will have any birthday, however the 2nd individual have to have a distinct birthday, which has a probability of 364/365 (since there are 365 days in a year and one day has already been "used" by the first person). The probability that the third individual will have a different birthdate from the previous two is 363/365. Continuing in this way,

The probability that all 23 people have different birthdays is:

(365/365) x (364/365) x (363/365) x ...

Since the probabilities of all conceivable outcomes must sum up to 1, subtract the likelihood that at least two persons will have the same birthdate from one:

P(at least 2 people have the same birthday) = 1 - (365/365) x (364/365) x (363/365) x ... x (344/365)

P(at least 2 people have the same birthday) = 0.5073

Therefore, the probability that at least 2 people in a group of 23 have the same birthday is approximately 0.5073 or 50.73%

The minutes that it would take for the 0702 bus to go from Birmingham to Coventry is 92 minutes.

The latest time that Steve should leave his house so as to get to work on time is 07 56 hours .

If the bus from Birmingham leaves at 07 02 hours, it would reach Coventry at 08 34. The time taken is therefore :

= 08 34 - 07 02

= 1 hour 32 minutes

In minutes, this is:

= 60 minutes in an hour + 32

= 92 minutes

The total time it would take Steve to reach Coventry from Birmingham would be:

= Time to Coventry + Time spent walking from house + Time spent walking in Coventry

= 92 minutes + 9 + 12

= 113 minutes

The time Steve should leave his house at the latest is:

Answer:

he is incorrect because Jackson also has 4 whole bags because 13/3 is a mixed number therefore jackson really has 4 13/3 or 4 1/3 which would be the amount as Fraud

Step-by-step explanation:

Answer:

We can use the formula for exponential growth:

A = P(1 + r)^t

where:

A = final amount

P = initial amount

r = annual growth rate (as a decimal)

t = time (in years)

Let's plug in the values:

P = 540

r = 0.039

t = 2035 - 2015 = 20

A = 540(1 + 0.039)^20

A ≈ 891

Therefore, the local government of Central Village can predict there will be approximately 891 houses in 2035.

Answer:

To solve this problem, we can use the formula for compound interest:

A = P(1 + r)^n

where:

A = the final amount

P = the initial amount

r = the annual interest rate (as a decimal)

n = the number of years

In this case, we want to find the final amount (the number of houses in 2035), given the initial amount (540 houses in 2015), the annual interest rate (3.9%), and the number of years (20 years from 2015 to 2035).

So, we can plug in the values and solve for A:

A = 540(1 + 0.039)^20

A = 540(1.039)^20

A = 540(2.011)

A = 1086.54

Rounding to the nearest whole number, we get:

A ≈ 1087

Therefore, the local government of Central Village can predict there will be about 1087 houses in 2035.

What is the formula to calculate standard deviation?

The formula to calculate standard deviation is:

SD = sqrt [(Σ(xi - μ)²) / N]

Where, SD = standard deviation

x = individual data points

μ = mean of the sample

N = sample size

What is the formula for z-score?

The formula for z-score is:

z = (x - μ) / σ

Where,

z = z-score

x = raw score

μ = mean of the population

σ = standard deviation of the population

Given that, The average BMI (body mass index) value of children 9 years old is 18.4 with a standard deviation of 4.5.

To find the probability that a randomly selected 9-year-old has a BMI greater than 26.8, we have to find the z-score.

z = (x - μ) / σz = (26.8 - 18.4) / 4.5z = 1.86

Now, we have to find the probability from the z-table, which is 0.9686. But we have to find the probability greater than 26.8, so we have to subtract it from 1.1 - 0.9686 = 0.0314 ≈ 0.031

Therefore, the probability that a randomly selected 9-year-old has a BMI greater than 26.8 is 0.031. Hence, the answer is 0.031.

One way to solve this system of inequalities is to graph the inequalities and see which ordered pair lies in the shaded region that is common to both inequalities

See the graph and each of the ordered pairs. Only (2, 0) lies entirely within the shaded region

(-1, 0) lies on the intersection of the two lines so it will satisfy the >= inequality but not the < inequality

Answer (2, 0)

However if you cannot use graphing then a brute force method must be used to see which ordered pair satisfies both inequalities

a. (-1, 0)
Check y < 2x + 2 ?
=>  0 < 2(-1) + 2 ?
=> 0 < -2 + 2
0 < 0 ? False
Eliminate option a

b. (0, 3)
y < 2x + 2?
=> 3 < 2(0) + 2?
3 < 2? False
Eliminate option b

c. (2, 0)
y < 2x + 2?
=> 0 < 2(2) + 2 ?
=>  0 < 4 + 2
=> 0 < 6 True

Move to the second inequality
y ≥ -x - 1?
0 ≥ -2 - 1
0 ≥ -3 True

So option c is the correct choice

While it is not necessary to check option d, let's do it anyway
d. (-1, -4)
y < 2x + 2 ?
-4 < 2(-1) + 2 ?
-4 < -2 + 2 ?
-4 < 0 ? True

Step-by-step explanation:

Let's assume that the length of the slide is represented by the variable "x".

Based on the information provided in the question, Bridgette walks 1 meter from the end of the slide back to the ladder and climbs 3 meters to reach the top of the slide again. Therefore, the total vertical distance Bridgette covers in one trip down and up the slide is 1 + x + 3 = x + 4 meters.

The length of the slide is the hypotenuse of a right triangle formed by the slide and the total vertical distance Bridgette covers in one trip down and up the slide. Using the Pythagorean theorem, we can write: x^2 = (x + 4)^2 - 1^2

Simplifying this equation, we get: x^2 = x^2 + 8x + 16 - 1

7x = 15

x = 2.14 (rounded to the nearest tenth)

Answer: We can use the Pythagorean theorem to find the length of the rectangle. The Pythagorean theorem states that in a right triangle, the square of the hypotenuse (the longest side) is equal to the sum of the squares of the other two sides. In this case, the diagonal is the hypotenuse and the width and length of the rectangle are the other two sides.

Let's use "l" to represent the length of the rectangle:

l^2 + 14^2 = 29^2

l^2 = 29^2 - 14^2

l^2 = 561

l = sqrt(561)

l ≈ 23.67 feet

Now that we know the length and width of the rectangle, we can use the formula for the perimeter, which is the sum of all four sides:

Perimeter = 2 * length + 2 * width

Perimeter = 2 * 23.67 + 2 * 14

Perimeter = 47.34 + 28

Perimeter = 75.34 feet

Therefore, the perimeter of the rectangle is approximately 75.34 feet.
