To find the point of intersection, solve the system of equations formed by the two lines. Substituting x=1 into either equation gives y=5. Therefore, the point of intersection is (1,5).

To find the point of intersection of two lines, we need to solve the system of equations formed by the two lines. In this case, the equations are y = 4x + 1 and y = -2x + 4.

Setting the equations equal to each other, we have 4x + 1 = -2x + 4. Solving for x, we get x = 1.  

Substituting x = 1 into either of the original equations, we find y = 4(1) + 1 = 5. Therefore, the point of intersection is (1, 5).

Answer:

A) x ≥ 0.074; B) x ≥ 0.108; C) x ≤ 0.006; D) 0.04 ≤ x ≤ 0.108

Step-by-step explanation:

68% of data will fall within 1 standard deviation of the mean; 95% of data will fall within 2 standard deviations of the mean; and 99.7% of data will fall within 3 standard deviations of the mean.

Breaking this down, we find that 34% of data fall from the mean to 1 standard deviation above the mean; 13.5% of data fall from 1 standard deviation above the mean to 2 standard deviations above the mean; 2.35% of data fall from 2 standard deviations above the mean to 3 standard deviations above the mean; and 0.15% of data fall above 3 standard deviations above the mean.

The same percentages apply to the standard deviations below the mean.

The highest 50% of data will fall from the mean to the end of the right tail.  This means the inequality for the highest 50% will be x ≥ 0.074, the mean.

The highest 16% of data will fall from 1 standard deviation above the mean to the end of the right tail.  This means the inequality for the highest 16% will be x ≥ 0.074+0.034, or x ≥ 0.108.

The lowest 2.5% of data will fall from 2 standard deviations below the mean to the end of the left tail.  This means the inequality for the lowest 2.5% will be x ≤ 0.074-0.034-0.034, or x ≤ 0.066.

The middle 68% will fall from 1 standard deviation below the mean to 1 standard deviation above the mean; this means the inequality for the middle 68% will be

0.074-0.034 ≤ x ≤ 0.074+0.034, or

0.04 ≤ x ≤ 0.108

The cutoff values using the 68-95-99.7 Rule for the given mutual funds data are calculated. The highest 50% lies between 4.0% and 10.8%, the highest 16% lies between 0.6% and 14.2%, the lowest 2.5% lies between -2.8% and 17.8%, and the middle 68% lies between 4.0% and 10.8%.

The cutoff values can be found using the 68-95-99.7 Rule, which states that approximately 68 percent of the data lies within one standard deviation of the mean, 95 percent lies within two standard deviations, and 99.7 percent lies within three standard deviations. With a mean of 7.4% and a standard deviation of 3.4%, we can determine the cutoff values:

Divide each large candy bar into thirds

so

[tex]\frac{1}{3}[/tex]

Now for each large candy bar you have 3 pieces of [tex]\frac{1}{3}[/tex]

step 2

Find the total number of candy bars pieces by proportion

[tex]\frac{1}{3}\frac{bar}{pieces} =\frac{6}{x}\frac{bar}{pieces}\\ \\x=6*3\\ \\x=18\ pieces[/tex]

Final answer:

To determine the total number of candy bar pieces after splitting 6 large bars into thirds, you multiply 6 by 3 resulting in 18 pieces.

Explanation:

The student's question is about dividing candy bars into thirds. If you start with 6 large candy bars and want to split each one into thirds, you end up with 6 groups of 3 pieces. To find the total number of candy bar pieces, you multiply the number of candy bars by the number of pieces you want to make from each bar, which is:

6 bars × 3 pieces per bar = 18 pieces.

Therefore, after splitting all the large candy bars into thirds, you will have a total of 18 candy bar pieces.

Answer:

0.7734; no, it does not.

Step-by-step explanation:

To find this probability we will use a z-score.  We are dealing with the probability of a sample mean being larger than a given value; this means we use the formula

[tex]z=\frac{\bar{X}-\mu}{\sigma \div \sqrt{n}}[/tex]

Our x-bar in this problem is 155, as that is the sample mean we are trying to find the probability of.  Our mean, μ, is 161 and our standard deviation, σ, is 31.  Our sample size, n, is 15.  This gives us

[tex]z=\frac{155-161}{31\div \sqrt{15}}=\frac{-6}{8.0042}=-0.75[/tex]

Using a z table, we see that the area under the curve less than this, corresponding with probability less than this value, is 0.2266.  This means that the probability of the sample mean being larger than this is

1-0.2266 = 0.7734, or 77.34%.

Since there is a 77.34% chance of the passengers having a mean weight that is too heavy, this elevator is not safe.

The probability that the elevator is overloaded using the normal distribution principle is 0.7870

Given the Parameters :

Using the relation :

Zscore = (xbar - μ) ÷ (σ/√(n))

Zscore = (155 - 161) ÷ (31/√15)

Zscore = - 0.796

The probability that lift is overloaded can be expressed thus :

P(Z ≥ - 0.796) = 1 - P(Z ≤ - 0.796)

Using a normal distribution table ; PP(Z ≤ - 0.796) = 0.2130

P(Z ≥ - 0.796) = 1 - 0.2130

P(Z ≥ - 0.796) = 0.7870

Therefore, the probability that weight is overloaded is 0.7870

  2.  x = 9√2

Step-by-step explanation:

For these, it is helpful to remember that the side lengths of a 30°-60°-90° triangle have the ratio 1 : √3 : 2, and those of a 45°-45°-90° triangle have the ratio 1 : 1 : √2.

1. 14 is the shortest side, and x is the longest side, so ...

  x = 2·14 = 28

  y = (√3)·14 = 14√3

__

2. 18 is the longest side and x is the shortest side of this 45°-45°-90° triangle, so ...

Answer:

[tex]y=\frac{\sqrt{x} -8}{-2}[/tex]

Step-by-step explanation:

To find an inverse, switch x and y values in the equation. Then solve for y.

[tex]F(x) = (8-2x)^2\\x = (8-2y)^2\\\sqrt{x} = 8 - 2y\\\sqrt{x} -8 = -2y\\\frac{\sqrt{x} -8}{-2} =y[/tex]

Replace x in the second equation with the value of x from the first one.

x = -3y

x + y = -6

-3y + y = -6

Simplify:

-2y = -6

Divide both sides by -2:

y = -6 / -2

y = 3

Now replace Y with 3 in one of the equations to solve for x:

x = -3y = -3(3) = -9

X = -9, Y = 3

The salary of the real estate broker = $18,000

Commission earned on total sales = 4% or 0.04

Total income earnings = $55,000

Let the total sales be = x

Equation becomes :

[tex]18000+0.04x=55000[/tex]

[tex]0.04x=55000-18000[/tex]

[tex]0.04x=37000[/tex]

[tex]x=925000[/tex]

Hence, the real estate broker must sell $925,000 worth of real estate to earn $55,000.

To earn $55,000 total, the real estate broker must sell $925,000 in total.

To find out how much the real estate broker must sell to earn $55,000 total, we need to consider both her base salary and her commission. Let's set up an equation to solve for the total sales needed:

$18,000 + 0.04x = $55,000

Subtracting $18,000 from both sides gives:

0.04x = $37,000

Dividing both sides by 0.04 gives:

x = $925,000

Therefore, the real estate broker must sell $925,000 in total to earn $55,000.

Polygons are closed figures based on a plane that are characterized by their sides and angles. Without an image or description of the polygon, it's impossible to identify the specific polygon indicated.

In mathematics, polygons are divided based on many factors such as the number of sides, length of sides, angle measures, etc. However, without the image or description of the polygon, I can't definitively tell what polygon you're referring to. For example, a polygon could be anything from a triangle (3 sides) to a decagon (10 sides). Remember, a polygon is basically a closed figure formed by three or more sides in a plane.

- It is a geometric series with:

- first term a = 3/2 and common ratio r = 9/8 ÷ 3/2 = 3/4

* The difference between the convergent and divergent

  in the geometric series is :

- If the geometric series is given by  sum  = a + a r + a r² + a r³ + ...

* Where a is the first term and r is the common ratio

* If |r| < 1 then the following geometric series converges to a / (1 - r).  

- Where a/1 - r is the sum to infinity

* The proof is:

∵ S = a(1 - r^n)/(1 - r) ⇒ when IrI < 1 and n very large number

∴ r^n approach to zero

∴ S = a(1 - 0)/(1 - r) = a/(1 - r)

∴ S∞ = a/1 - r

* If |r| ≥ 1 then the above geometric series diverges

∵ r = 3/4

∴ r < 1

Step-by-step explanation:

Present area = 12 * 14 = 168 square meters

The area has to increase by a factor of 255 / 168 = 1.5178571429

Therefore, the width and length are increased by a factor of the

square root of 1.5178571429 = 1.2320134508

So the width becomes

12 * 1.2320134508 =  14.7841614091

and the length becomes

14 * 1.2320134508 =  17.2481883107

That's roughly 14.78 by 17.25 and the area equals
