As per the distance concept, the speed of the buses are 79 km/h and 69km/h if the two buses leave a station at the same time and travel in opposite directions.

Distance

Distance refers the physical length or an approximation based on other physics or common usage considerations.

Given,

Two buses leave a station at the same time and travel in opposite directions. One bus travels 10 slower than the other. If the two buses are 276 miles apart after 2 hours,

Here we need to find the rate of each bus.

Let us consider the speed of the first bus is x km/h.

Then the speed of the other bus = (x - 10) km/h

We know the formula of distance is,

Distance = time × speed

When we combined speed then we get,

=> x + x - 10 = (2x - 10) km/h

=> 2(2x - 10) =276

When we expand the equation, then we get,

4x - 40 = 276

4x = 316

After calculating,

x = 79 km/h

The speed of first bus x = 79 km/h

Speed of the second bus = x - 10 = 79 - 10 = 69 km/h

Therefore, the speed of the buses are 79 km/h and 69/km/h if the two buses leave a station at the same time and travel in opposite directions.

The approximate value of the height f the tree when the base diameter is 3.2 meters is 119.47 meters

From the question, the equation  of the function of height is given as

h = 35d²/3

Also from the question, we have the base diameter of the fir tree to be

d = 3.2m

Next, we substitute 3.2 for d in the equation of the function of height given as

h = 35d²/3

So, we have the following equation:

h = 35 x 3.2²/3

Evaluate the exponent

So, we have

h = 35 x 10.24/3

Evaluate the product

So, we have the following equation:

h = 358.4/3

Evaluate the quotient

This gives

h = 119.47

Hence, the height is 119.47 meters

The price of 1 yard of blue fabric and 1 yard of green fabric is obtained by solving the system of linear equations and it is $8

Let

x = price of blue fabric per yard

y = price of green fabric per yard

"The blue fabric costs $2 more per yard than the green fabric" means:

x = y + 2  (Equation 1)

" LaTanya buys 6 yards of blue fabric and 9 yards of green fabric and pays $57" means:

6x + 9y = 57  (Equation 2)

Substitute equation 1 into equation 2:

6x + 9y = 57

6 (y + 2) + 9y = 57

6y + 12 + 9y = 57

15 y = 45

y = 3

Substitute y = 3 into equation 1

x = 3 + 2 = 5

Hence, the price of blue fabric is $5 per yard while the green fabric is $3 per yard.

The price of 1 yard of blue fabric and 1 yard of green fabric = x + y = 3 + 5 = $8

Complete question:

LaTanya buys 6 yards of blue fabric and 9 yards of green fabric. The blue fabric costs $2 more per yard than the green fabric. She pays a total of $57. What would be the combined cost of 1 yard of blue fabric and 1 yard of green fabric?

Step-by-step explanation:

we get x=y =0 which gives 0 perimeter or x=y this implies rectangle must be a square

1. Method of Langrage Multipliers:

To find the extremum values of f(x,y) subject to constraint g(x,y) = k

find all values of x,y and λ, such that :

Δλ(f,x) = λΔg(x,y)

And  g(x,y) = k

2. let the two side of the rectangle be x and y

therefore

f(x,y) = xy And g(x,y)= 2(x+y)=p

fₓ=λgₓ => y=2λ ----------------- 1

fy = λgy => x = 2λ----------------2

using equation and 1 and 2

λ=0, but this is not possible because tis implies x = y = 0, which gives  0 perimeter

By evaluating the equation in x = 2030, we can estimate the price to be $51.60.

We know that the equation:

y = 1.67*x - 3338.5

Models the relationship between the year, x, and the average ticket price of a Miami Marlins baseball ticket.

We know that this relationship works for the years 2006 to 2021, but can be used to estimate the price for years after and before that.

if we use x = 2030, we will get:

y = 1.67*2030 - 3338.5 = 51.6

This will be the price, in dollars, of a game in the year 2030.

a. The expected value is 0.40

b. The standard error is 0.0024

Given that:

Sample size, n=100

Population proportion, p=0.40

a) The expected value of the sample proportion is defined as:

E(^p)=p

now,

E(^p)=0.40

b) The standard error of the sample proportion is defined as:

SE(^p) = √p(1-p)/n

SE(^p) = √0.40(1-0.40)/100

SE(^p) = 0.0024

c) The sampling distribution of the sample proportion is normally distributed with the expected value of the sample proportion of 0.40.

Therefore,

E(^p) = 0.40

d) The central limit theorem states that the sample statistic (sample proportion) tends to the population parameter (population proportion) as the sample size tends to infinity (OR n→∞).
