The slope of points (1,3) and (4,5) will be 2/3.

Slope or the gradient is the number or the ratio which determines the direction or the steepness of the line. The slope is also defined as the ratio of the rise and the run of the line.

Given that the line is passing through points (1,3) and (4,5). The slope of the line will be calculated as,

Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )

Slope = ( 5 - 3 ) / ( 4 - 1)

Slope = 2 / 3

Therefore, the slope of points (1,3) and (4,5) will be 2/3.

The value that the linear equation predicts for the year 2001 is 4652.15

The discrepancy between the actual and anticipated value is 2173.85

Given data;

Here, we present the dataset from the United Nations, which contains information on the number of kilowatt-hours of wind energy generated globally. The data set provides statistics on the US for 25 years, from 1990 to 2014, in millions of kilowatt-hours.

The linear equation for the first 11 years of data, from 1990 to 2000, must be determined.

To determine how much the actual value and anticipated value for the year 2001 differ in Quantity, we must first forecast the value for the year 2001 using our fitted equation with y-intercept.

It will be written as y = m(x) + c.

where,

The dependent variable is y. (in our example is quantity)

The independent variable is x. (in our example is the year)

'm' is equal to the slope of the variable X.

'C' is a constant.

The fitted equation is provided as follows:

Quantity = 186.87 (year) - 369274.72

Now that the value for the year 2001 has been provided,

Quantity = -1868.87 -369274.72 

Quantity = 4652.15

The value that the linear equation predicts for the year 2001 is 4652.15.

The precise figure for 2001 is 6806.

For the year 2001, the discrepancy between the actual and anticipated values is

6806 - 4652.15 = 2173.85

The distinction is 2173.85.

(2173.85/6806)*100 is the percentage difference.

As a result, the difference between the actual value and the forecasted value for the year 2001 is 31.94%.

Hence,

The value that the linear equation predicts for the year 2001 is 4652.15

The discrepancy between the actual and anticipated value is 2173.85

To write a polynomial in standard form, simplify and then arrange the terms in descending order. Expand (2x+1)(x−3) ( 2 x + 1 ) ( x - 3 ) using the FOIL Method.

The vehicles will meet at 0845 at a distance of 64 km from P when they move at the respective speeds.

The car moves at a speed of 80km/h from P to Q and it takes time t

t = 9.30 - 8.00 = 1 hour 30 minutes or 1.5 hours

Distance covered = speed × time

Distance = 80 × 1.5 = 120 km

Now et the cars meets at a distance of x km from P.

times taken by the car to cover x km = x/80 hours

The lorry travels 120 - x in that same time.

time taken = 70/(120 - x)

Now the time taken must be equal.

Therefore we will form an equation to calculate x.

(120 - x) / 70 = x / 80

or, 960 - 8x = 7x

or, 15x = 960

or, x = 64

Therefore the cars will meet at 64 km from P.

Now time taken by the car to cover 64 km = 64/80 = 0.8 hours = 48 minutes

Hence the cars will meet at 0845 hours.

Answer:

y = [tex]\frac{3}{4}[/tex] x + 8

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

here m = [tex]\frac{3}{4}[/tex] , then

y = [tex]\frac{3}{4}[/tex] x + c ← is the partial equation

to find c substitute (- 4, 5 ) into the partial equation

The option that is not an isometry from the given transformations is 3). Point reflection.

An Isometry refers to a transformation that leads to the distance and length  of a shape being preserved when it is transformed.

Translations and rotations preserve the shape of a figure during transformation which means they preserve length which makes them an isometry. The same is true of line reflections.

Point reflections on the other hand, will lead to a change in dimensions for the figure being transformed.

The vertex of the function f(x) = x^2 + 12x is (-6, -36).

The concept that will be used here is the concept of Standard equation of a curve in vertex form.

The standard equation can be written as

f (x) = ax^2 + bx + c

Then the Vertex is the (h,k)

Then the X-coordinate of the vertex  can be written as (h = -b/2a) where  k = f(h)

If we compare the given equation with the standard form, then we have

a = 1, b = 12 and c = -10

Then we can input the values into the  (h = -b/2a)

h =[ -12/2(1)] = - 6

Then we can substitute the value of h in f (x) which is f(x) = x2 + 12x

k = f(h)= f (-6) =[ (-6)2 + 12 (-6)]

= [36 - 72] = -36

In most of the cases airlines charges a fees for baggage weigh in excess of 50 pounds. Then about 94.06% passengers incur this fees.

When the distribution is normal, we use the z-score formula.

In a set with mean and standard deviation , the z-score of a measure X is given by:

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.

Given That,

Mean (μ) = 45 pounds and Standard Deviation (σ) = 3.2

This means that μ = 46 , σ = 3.2

Since, Most airlines charges a fee for baggage that weigh in excess of 50 pound.

Then, As a proportion this is 1 subtracted by the P - value of Z when

X =50. So,

      Z = X - μ / σ

⇒ Z = 50 -45/ 3.2

⇒ Z = 5/3.2

⇒ Z = 1.56

when Z = 1.56 has a P- value of 0.9406

Now, 0.9406 × 100%

       = 94.06%

Therefor, 94.06% of airline passengers incur this fees.
