Express Using algebra Z deacresed by 15%. show your all work.

Answer:

Let's use "d" to represent the time the team spent on each drill.

Since the team spent the same amount of time on each drill, and they worked on 5 drills, the total time spent at practice before Jayla arrived can be represented as:

5d

We know that Jayla was 15 minutes late, so when she arrived, the team had already been practicing for 15 minutes. Therefore, the total time she spent practicing is:

40 minutes = 5d - 15

Now we can solve for "d":

5d - 15 = 40

5d = 55

d = 11

So the team spent 11 minutes on each drill.

The equation we used is:

5d - 15 = 40

The prοbability that the mean gain fοr the sample was between 400 and 800 is apprοximately 0.603.

The distributiοn οf sample means apprοaches a nοrmal distributiοn with mean equal tο the pοpulatiοn mean and standard deviatiοn equal tο the pοpulatiοn standard deviatiοn divided by the square rοοt οf the sample size.

standard errοr οf the mean = standard deviatiοn / square rοοt οf sample size

[tex]s = 1539 / \sqrt{(34)}\\\\s = 263.8[/tex]

we can standardize the sample mean using the fοrmula:

z = (sample mean - pοpulatiοn mean) / standard errοr οf the mean

z1 = (400 - 651) / 263.8 ≈ -0.953

z2 = (800 - 651) / 263.8 ≈ 0.564

P(-0.953 < z < 0.564) ≈ 0.603

Step-by-step explanation:

The distance from the sun to Canopus in parsecs is approximately 229.4 parsecs.

Absolute magnitude is a measure of the intrinsic brightness of a celestial object, such as a star or a galaxy, as it would be seen from a standard distance of 10 parsecs (about 32.6 light-years) away. It is defined as the magnitude (brightness) that the object would have if it were located at this standard distance, and it is determined by the object's luminosity, or total amount of energy radiated per unit time.

We are given that the absolute magnitude of Canopus is M = -3.1, and its apparent brightness is m = -0.72. We can use the formula (m - M) = 5log(d/10) to find the distance, d, from the Sun to Canopus in parsecs.

Substituting the given values, we get:

-0.72 - (-3.1) = 5log(d/10)

Simplifying:

2.38 = 5log(d/10)

log(d/10) = 2.38/5 = 0.476

Taking antilogarithm on both sides, we get:

d/10 = 10^(0.476)

d = 10^(0.476) * 10 = 229.4 parsecs

Therefore, the distance from the Sun to Canopus is approximately 229.4 parsecs.

Therefore, the range of the function is all real numbers except for 0. In interval notation, this can be written as (-∞, 0) U (0, ∞).

In mathematics, a function is a relation between two sets, where each element in the first set (called the domain) is associated with exactly one element in the second set (called the range). Formally, a function f from a set A to a set B is a rule that assigns to each element a in A a unique element b in B, denoted by f(a). The set A is called the domain of the function, and the set B is called the range.

Here,

The given function is y = x/(8-x).

To find the range of this function, we need to determine the possible values of y for all possible values of x.

First, we note that the function is undefined when the denominator (8-x) equals zero. Therefore, x cannot be equal to 8.

Next, we consider the behavior of the function as x approaches positive infinity and negative infinity.

As x approaches positive infinity, the value of y approaches zero. This is because the x term in the numerator grows much more slowly than the 8-x term in the denominator, causing the overall value of the function to approach zero.

As x approaches negative infinity, the value of y approaches negative infinity. This is because the x term in the numerator becomes very negative while the 8-x term in the denominator approaches 8, causing the overall value of the function to become very negative.

For the Venn Diagram with the code 0000, the 7-bit Hamming code extended is 0011000.

What is a Venn Diagram?

In order to solve problems based on the sets, we can use a Venn diagram to depict the logical relationship between sets and their components. Although other closed figures like squares may be used, a Venn diagram commonly uses intersecting and non-intersecting circles to indicate the relationship between sets.

To extend the four-bit code word "0000" to a seven-bit Hamming code word, we need to add three parity bits to the code word.

These parity bits are calculated based on the positions of the 1's in the code word.

To determine which subset of the Venn Diagram to put each parity bit in, we can use the following rules -

Parity bit 1 covers all bit positions that have an odd index (i.e., 1, 3, 5, 7, etc.).

Parity bit 2 covers all bit positions that have a "2" bit in their binary representation (i.e., 2, 3, 6, 7, etc.).

Parity bit 3 covers all bit positions that have a "4" bit in their binary representation (i.e., 4, 5, 6, 7, etc.).

Using these rules, we can fill in the Venn Diagram as follows -

Subset 1: 0 (bit position 1)

Subset 2: 00 (bit positions 2, 3)

Subset 3: 000 (bit positions 4, 5, 6)

Subset 4: 0000 (bit positions 7, 8, 9, 10)

Parity bit 1: 1 (covers bit positions 1, 3, 5, 7, 9, 11, 13)

Parity bit 2: 1 (covers bit positions 2, 3, 6, 7, 10, 11, 14)

Parity bit 3: 0 (covers bit positions 4, 5, 6, 7, 12, 13, 14)

So, the seven-bit Hamming code word that extends the four-bit code word "0000" is -

0011000

The first three bits (001) represent Subset 3, which contains the original code word "0000".

The next three bits (100) are the parity bits, and the last bit (0) represents Subset 4.

Therefore, the 7-bit code is obtained as 0011000.

Answer:

We can expect the town to have a population of approximately 32,413 in the 2030 census if the growth rate remains at 1.8% per year.

Step-by-step explanation:

To calculate how long it will take for the town to double in size, we can use the Rule of 70, which states that the time it takes for a quantity to double is approximately 70 divided by the annual growth rate as a percentage.

So in this case, the annual growth rate is 1.8%, and therefore the doubling time is approximately 70/1.8 = 38.89 years (rounded to two decimal places).

To estimate the population in the 2030 census, we can use the same growth rate of 1.8% per year. Starting with the 2020 population of 27,370, we can use the formula:

Population = Initial population x (1 + growth rate)^number of years

Plugging in the numbers, we get:

Population = 27,370 x (1 + 0.018)^10 = 32,413 (rounded to the nearest whole number)

Therefore, we can expect the town to have a population of approximately 32,413 in the 2030 census if the growth rate remains at 1.8% per year.

The equation that represents the total cost of the TV is Option B: 1/4x + 1/3 × 3/4x + 1/4x + 20 + 120 = x.

What is an equation?

A mathematical definition of an equation is a claim that two expressions are equal when they are joined by the equals sign ("=").

Let's represent the total cost of the TV with the variable x.

According to the problem, Adam's first payment was 1/4 of the total price, so he still owed 3/4 of the price.

His second payment was 1/3 of the remaining amount, which is 1/3 × 3/4x = 1/4x, leaving him with 3/4x - 1/4x = 1/2x to pay.

His third payment was $20 more than the first payment, so it was 1/4x + 20, leaving him with 1/2x - (1/4x + 20) = 1/4x - 20 to pay.

Finally, his last payment was $120, so the remaining amount he owed was 1/4x - 20 - 120 = 1/4x - 140.

Adding up all of these payments, we get -

1/4x + 1/4x + 20 + 1/4x - 140 + 120 = x

Simplifying this equation, we get -

3/4x = 100

Multiplying both sides by 4/3, we get -

x = 400/3

Therefore, the equation is obtained as 1/4x + 1/3 × 3/4x + 1/4x + 20 + 120 = x.

As a result, the first pair of hikers is around 0.15 miles further away from camp than the second pair.

Step-by-step explanation:

Let's designate "x" for the distance travelled directly east or west and "y" for the distance directly north or south. Then, using the method below, determine how far each pair of hikers is from camp:

Distance is equal to sqrt(2xy*cos(angle) - xy + yy).

where "angle" is the angle at which the hikers veer away from their original path.

The first group of hikers includes:

Distance is equal to sqrt(((2cos(50°) + 1.2sin(50°))).

(1.2cos(50°) + 2 sin(50°))

(1.2sin(50°) + 2cos(50°)) = 2 - 2*

(1.25*cos(50°) + 1.2*cos(50°)*cos(130°))

approximately 2.53 miles.

The second group of hikers includes:

Distance is equal to sqrt(((2cos(40°) + 1.2sin(40°))).

-2sin(40°) + 1.2cos(40°) = 2

(1.2sin(40°) + 2cos(40°)) = 2 - 2*

(-2sin(40°) plus 1.2*cos(40°)*cos(140°))

about 2.38 miles.

As a result, the first pair of hikers is around 0.15 miles further away from camp than the second pair.

The dimensions of the rectangular field that maximize the enclosed area are 150 feet by 75 feet.

What is area?

An object's area is how much space it takes up in two dimensions. It is the measurement of the quantity of unit squares that completely cover the surface of a closed figure.

Let's call the length of the rectangle "l" and the width "w".

We can write two equations based on the given information -

Perimeter equation: 2l + 4w = 600 (since there are two sets of parallel sides, we have to add an extra "w" to the perimeter equation)

Area equation: A = 3lw (since the field is divided into 3 equal parts)

We want to maximize the enclosed area, which means we want to find the values of "l" and "w" that make the area as large as possible.

We can use the perimeter equation to solve for one of the variables in terms of the other -

2l + 4w = 600

2l = 600 - 4w

l = 300 - 2w

Now we can substitute this expression for "l" into the area equation -

A = 3lw

A = 3(300 - 2w)w

A = 900w - 6w²

To find the maximum area, we can take the derivative of this equation with respect to "w" and set it equal to zero -

dA/dw = 900 - 12w = 0

12w = 900

w = 75

So the width of each of the smaller rectangular plots is 75 feet. We can use the perimeter equation to find the length -

2l + 4w = 600

2l + 4(75) = 600

2l = 300

l = 150

Therefore, the dimensions value are obtained as 150 feet by 75 feet.

Answer:

y - 1 = 2(x + 2)

Step-by-step explanation:

Point-slope form is y - y₁ = m(x - x₁)

y - 1 = 2(x - -2)

=> y - 1 = 2(x + 2)

1. The rational expression representing the charge each attendee will have to pay is 300 + 55x.

2. Each attendee will have to pay $65 in order to cover the total cost.

The solution has been obtained by using arithmetic operations.

What are arithmetic operations?

All real numbers are thought to be adequately explained by the four basic operations, sometimes known as "arithmetic operations." The mathematical operations quotient, product, sum, and difference come after division, multiplication, addition, and subtraction.

1. We are given that it costs $300 plus $55 per person attending to host an event.

Let the number of attendees be x.

We get the expression as 300 + 55x.

2. We are given that 30 people are attending the event.

So, substituting x = 30 in the expression, we get

⇒ Total cost = 300 + (55 * 30)

⇒ Total cost = 300 + 1650

⇒ Total cost = $1950

Now, using the division operation, we get

⇒ Per person charge = 1950 ÷ 30

⇒ Per person charge = $65

Hence, the required solutions have been obtained.

Question: To host an event at a popular convention center, it costs $300 plus $55 per person attending.

1. Write a rational expression that represents how much you would need to charge each attendee in order to cover the cost of hosting the event. Let x be the number of attendees.

2. In the previous step you determined that for x number of people, the total cost for hosting the event is 300+55x. Now, adjust the expression to represent what each attendee would need to be charged to cover the total cost if 30 people were attending.

The number of coach tickets bought is 2 and the number of first class ticket bought is 2.

Sarah took 4 people including herself to a trip. She was able to purchase coach tickets for $140 and first class tickets for $1000.

She used her total budget for airfare for the trip, which was $2280.

Let's find the number of first class and coach tickets bought.

let

x  = number of first class ticket

y = number of coach ticket

Therefore, using equation

140x + 1000y  = 2280

x + y = 4

multiply equation(ii) by 140

140x + 1000y  = 2280

140x + 140y = 560

860y = 1720

y = 1720 / 860

y = 2

x = 4 - 2

x = 2

therefore,

number of coach tickets = 2

number of first class tickets = 2
