Step-by-step explanation:

The slope is \(\frac{3}{4}\)

What is slope ?

 A line's steepness and direction are determined by the slope of the line. Without actually using a compass, determining a line's slope in a coordinate plane can aid in determining whether the line is parallel, perpendicular, or not. Any two clearly separated points on a line can be used to calculate the slope of any line. Calculated using the slope of a line formula, the ratio of "vertical change" to "horizontal change" between two different locations on a line is determined.

here the given two pints are

\((x_1,y_1)=(-2,4)\\(x_2,y_2)=(6,10)\)

Now using slope formula,

slope m = \(\frac{y_2-y_1}{x_2-x_1}\)

=> slope m = \(\frac{10-4}{6+2}\)

=> slope m = \(\frac{6}{8}\)

=> slope m = \(\frac{3}{4}\)

Therefore the slope is \(\frac{3}{4}\).

Answer:

x=12

Step-by-step explanation:

Im not sure which measure you're talking about, but I'll show you what I did here:

A triangle = 180 degrees.

4x + 8x + 4x =16x

-8 - 1 - 3 = -12

180 = 16x - 12        -Add 12 to both sides

192 = 16x               -divide by 16 to get x by itself

12 = x

Angle A = 88 degrees (8 times 12 then subtract 8)

Angle B = 47 degrees (4 times 12 then subtract 1)

The Luminosity of a star is proportional to its Effective Temperature to the 4th power and its Radius squared." Example 1: Two stars are the same size, (RA=RB), but star A is 2x hotter than star B (TA=2TB): Therefore: Star A is 24 or 16x brighter than Star B.

Certainly! Let's consider an example with arbitrary numbers to illustrate the concept.

Let's assume Latoya's Coffee House has the following values:

Available ounces of grade A coffee: 100 ounces

Available ounces of grade B coffee: 80 ounces

Economy blend composition: 4 ounces of grade A coffee and 2 ounces of grade B coffee

Superior blend composition: 5 ounces of grade A coffee and 3 ounces of grade B coffee

Profit per economy blend package: $5

Profit per superior blend package: $7

Now, we can proceed to determine the number of packages of each blend that should be made to maximize the profit for the week.

Let's say Latoya's Coffee House produces 'x' packages of the economy blend and 'y' packages of the superior blend.

Profit for the economy blend: P_economy = 5 * x

Profit for the superior blend: P_superior = 7 * y

The total profit for the week, P_total, is given by:

P_total = P_economy + P_superior

P_total = 5x + 7y

We need to maximize P_total while considering the available ounces of grade A and grade B coffee.

The constraints are as follows:

4x + 5y ≤ 100 (Available ounces of grade A coffee)

2x + 3y ≤ 80 (Available ounces of grade B coffee)

Additionally, 'x' and 'y' should be non-negative since we cannot produce negative packages.

To solve this linear programming problem and find the optimal values for 'x' and 'y', we can use optimization techniques such as the simplex method or graphical methods.

The sector's needed area while adopting the center angle is 75.6°.

When two circle radii come together to form a vertex in the center of a circle, the result is a central angle.

This circle's arms could come from two different locations along its arc.

The intersection of the two radii produces a central angle that makes it easier to divide a circle into several halves.

Area of circle:

πr² = 121π

r² = 121

r = 11 m

Now, the area of the sector:

= θ/360 * πr²

= 28/360 * 3.14 * 11 * 11

= 72 * 379.94/360

= 72*1.05

= 75.6

Therefore, the sector's needed area while adopting the center angle is 75.6°.

The amount Arianna sold 80 milkshakes last week, and 35% of them had whipped cream on top. This means 28 milkshakes had whipped cream.

Arianna sold 80 milkshakes last week and 35% of them had whipped cream on top. This means that 35% of the total number of milkshakes, 80, had whipped cream. To calculate the amount of milkshakes with whipped cream, we must multiply the total number of milkshakes (80) by 35%. 35% of 80 is 28, so 28 milkshakes had whipped cream. To find the percentage, we divide the amount of milkshakes with whipped cream (28) by the total number of milkshakes (80). When we divide 28 by 80, we get 0.35, which is the same as 35%. Therefore, 35% of the milkshakes sold by Arianna last week had whipped cream on top.

Answer: neither

Step-by-step explanation:

For a graph to be parallel, it must have the same slope.

e.g., y = 2x    and    y = 2x + 1      are parallel because they both have the slope "2"

For a graph to be perpendicular, its slopes must be the reciprocal of each other, and the sign (positive/negative) is flipped

e.g., y = 2x    and    y = -1/2x + 1    are parallel because their slopes are reciprocals to each other, and the sign is flipped.

To know whether   y = 4x + 3    and    4x + y = 3 are parallel, perpendicular, or neither, we have to identify the slopes and use what was mentioned previously:

Identifying the slope:

y = 4x + 3        slope = 4

4x + y = 3   -->   y = -4x + 3           slope = -4

The slopes are different, so they are not parallel

As the slopes are not reciprocals, they are not perpendicular.

The graphs are neither parallel nor perpendicular.

To find the missing angles, we have to use the fact that the sum of the angles of a triangle is 180°. So, we add up the known angles, and then subtract the sum from 180°. For problem 3:Let x be the measure of the missing angle at the bottom right corner of the triangle.

We know that the other two angles are 65° and 43°.Therefore,x + 65° + 43° = 180°x + 108° = 180°x = 72°So the measure of the missing angle is 72°.For problem 4:Let y be the measure of the missing angle at the bottom left corner of the triangle. We know that the other two angles are 70° and 50°.Therefore,y + 70° + 50° = 180°y + 120° = 180°y = 60°So the measure of the missing angle is 60°.Hence, the measures of the missing angles for problems 3 and 4 are 72° and 60°, respectively.

The functiοn t satisfies bοth the additivity and hοmοgeneity cοnditiοns, it is indeed a linear transfοrmatiοn frοm P₂ tο P₂.

A linear transfοrmatiοn is a functiοn that preserves the basic structure οf vectοr spaces. It maps vectοrs frοm οne vectοr space tο anοther while respecting the οperatiοns οf vectοr additiοn and scalar multiplicatiοn.

Tο determine whether the functiοn t: P₂ → P₂ is a linear transfοrmatiοn, we need tο check if it satisfies the prοperties οf linearity.

Let's cοnsider a pοlynοmial p(x) = a₀ + a₁x + a₂x² in P₂, where a₀, a₁, and a₂ are cοnstants.

The functiοn t takes the pοlynοmial p(x) and maps it tο anοther pοlynοmial q(x) = (a₀ a₁ a₂) (a₁ a₂)x a₂x².

Fοr t tο be a linear transfοrmatiοn, it needs tο satisfy twο cοnditiοns:

Additivity: t(u + v) = t(u) + t(v)

Hοmοgeneity: t(cu) = c * t(u)

Let's check these cοnditiοns:

Additivity:

t(p(x) + q(x)) = t(a₀ + a₁x + a₂x² + b₀ + b₁x + b₂x²)

= t((a₀ + b₀) + (a₁ + b₁)x + (a₂ + b₂)x²)

= ((a₀ + b₀) (a₁ + b₁) (a₂ + b₂)) ((a₁ + b₁) (a₂ + b₂))x ((a₂ + b₂)x²)

= (a₀ a₁ a₂) (a₁ a₂)x a₂x² + (b₀ b₁ b₂) (b₁ b₂)x b₂x²

= t(a₀ + a₁x + a₂x²) + t(b₀ + b₁x + b₂x²)

= t(p(x)) + t(q(x))

The functiοn t satisfies the additivity cοnditiοn.

Hοmοgeneity:

t(c * p(x)) = t(c * (a₀ + a₁x + a₂x²))

= t(c * a₀ + c * a₁x + c * a₂x²)

= (c * a₀ c * a₁ c * a₂) (c * a₁ c * a₂)x (c * a₂)x²

= c * (a₀ a₁ a₂) (a₁ a₂)x a₂x²

= c * t(p(x))

The functiοn t satisfies the hοmοgeneity cοnditiοn.

Since the functiοn t satisfies bοth the additivity and hοmοgeneity cοnditiοns, it is indeed a linear transfοrmatiοn frοm P₂ tο P₂.

The new price of the car after the 4% reduction is $18,240

Percentage is simply number or ratio expressed as a fraction of 100.

Given that,

To determine the new price of the car after reduction;

New price = Initial price × ( 100% - 4% )

New price = Initial price × ( 96% )

Note that 96% is the same as 96/100

New price = $19,000 × 96/100

The margin of error of the 98.4% confidence interval for snapdragons  is 3.71.

The midpoint of the range is calculated by adding the upper and lower bounds and then dividing by two. So, the sample mean is `(20.91 + 38.43) / 2 = 29.67`.

The margin of error is calculated by multiplying the critical value of z* (1.96 for a 98.4% confidence level) by the standard error of the mean. The formula for calculating the margin of error is:

`Margin of error z*(standard deviation/√n`).

The formula is `range/4 = 1.96 * standard deviation/√n`.Now, solve for the standard deviation:

`standard deviation = (range/4) * √n / 1.96`

Substituting the values: `(38.43 - 20.91)/4 = 1.96 * standard deviation/√n`

Simplifying the equation: `4.26 = (1.96*standard deviation)/√n`

Squaring both sides: `4.26^2 = 3.8416 = (1.96^2 * standard deviation^2)/n`

Substituting the value of the standard deviation: `3.8416 = (1.96^2 * ((38.43 - 20.91)/4)^2) / n`

Solving for n: `n = ((1.96^2 * ((38.43 - 20.91)/4)^2) / 3.8416) = 31.54`

Now that we know the sample size, we can calculate the standard error of the mean:

`standard error = standard deviation/√n = ((38.43 - 20.91)/4)/√31.54 = 1.89`.

The margin of error is `1.96 * 1.89 = 3.71`.

Step-by-step explanation:

In throwing a dice, there are 6 possible outcomes, namely 1, 2, 3, 4, 5 and 6.

P=(no. of favourable outcomes)/(no. of possible outcomes)

When we multiply the probability of an event with no. of trials, the we get the expected frequency of that event.

1) P(getting 1)=1/6

expected frequency of getting 1

=P(getting)1)×no. of trials

=1/6×600=100

But it is given that one is scored 200 times, so it makes a large difference from expected frequency, which is 100.

Therefore, the dice is not fair.

2) P(getting a tail)=0.3
