Answer:

[tex]y = 4x - 47[/tex]

Step-by-step explanation:

Equation of a line:

The equation of a line has the following format:

[tex]y = mx + b[/tex]

In which m is the slope and b is the y-intercept.

Parallel lines:

When two lines are parallel, they have the same slope.

8x-2y=7

Placing into the format, we have thtt:

[tex]2y = 8x - 7[/tex]

[tex]y = 4x - \frac{7}{2}[/tex]

Slope of 4.

This means that the desired line has the following equation:

[tex]y = 4x + b[/tex]

Point of (12,1)

This means that when [tex]x = 12, y = 1[/tex]

We use this to find b.

[tex]y = 4x + b[/tex]

[tex]1 = 48 + b[/tex]

[tex]b = -47[/tex]

So, the line has the equation:

[tex]y = 4x - 47[/tex]

Answer:

∠MKL = 81.13°

Step-by-step explanation:

240 mm has to be the equal legs because two 74 mm legs wouldn't work with a 240 mm base leg.

Drop a line from m to be perpendicular to LK.

This divides LK into two 37 mm segments.

cos ∠MKL = 37/240

cos ∠MKL = 0.1542

∠MKL = 81.13°

Answer:

-8, -14, -20, -26, -32, -38

Step-by-step explanation:

if we do this equation:

14 - 8 = 6

20 - 14 = 6

26 - 20 = 6  and you will do this until you get the answer you want.

so the arithmatic squence is -8, -14, -20, -26, -32, -38

Answer:

4.46% probability that the pressure will exceed this value.

Step-by-step explanation:

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

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 pvalue, we get the probability that the value of the measure is greater than X.

Gaussian distribution with a mean value of 69 psi and a standard deviation of 10 psi.

Gaussian distribution = normal.

This means that [tex]\mu = 69, \sigma = 10[/tex]

If it is important that the pressure stays below 86 psi, what is the probability (in percent) that the pressure will exceed this value?

As a proportion, this probability is 1 subtracted by the pvalue of Z when X = 86. So

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{86 - 69}{10}[/tex]

[tex]Z = 1.7[/tex]

[tex]Z = 1.7[/tex] has a pvalue of 0.9554

1 - 0.9554 = 0.0446

0.0446*100 = 4.46%

4.46% probability that the pressure will exceed this value.

Answer:

45

Step-by-step explanation:

If you write it out it will look like this, 2x+45+x=180

3x+45=180

3x+45=180

    -45   -45

3x=135

/3   /3

x=45

Answer:

x=45

Step-by-step explanation:

Straight angles/lines are equal to 180 degrees. If you add the equations together to get 180 and simplify you'll find the answer. So, start out with the equation 2x+45+x=180.

1. Add like terms. 3x+45=180

2. Subtract 45 from both sides. 3x=135

3. Divide by 3 on both sides to get x by itself. x=45

4. Just to make sure, plug in 45 for x. 2(45)+45+45=180. Sure enough, it works!

Answer:

0.35 = 35% probability that a married couple watches the movie

Step-by-step explanation:

Conditional Probability

We use the conditional probability formula to solve this question. It is

[tex]P(B|A) = \frac{P(A \cap B)}{P(A)}[/tex]

In which

P(B|A) is the probability of event B happening, given that A happened.

[tex]P(A \cap B)[/tex] is the probability of both A and B happening.

P(A) is the probability of A happening.

The probability that a husband watches the movie, given that his wife does, is 0.7.

This means that [tex]P(B|A) = 0.7[/tex]

The probability that a wife watches the movie is 0.5.

This means that [tex]P(A) = 0.5[/tex]

What is the probability that a married couple watches the movie?

Both, so:

[tex]P(B|A) = \frac{P(A \cap B)}{P(A)}[/tex]

[tex]P(A \cap B) = P(B|A)*P(A) = 0.7*0.5 = 0.35[/tex]

0.35 = 35% probability that a married couple watches the movie

Answer:

Step-by-step explanation:

The figure and its image are symmetrical about the origin, so the following three transformations are equivalent:

  1. reflection across the origin

  2. rotation 180° about the origin

  3. reflection across both x- and y-axes, in either order

__

The figure itself has left-right symmetry, so only one reflection is necessary to map the figure to its image: reflection across a horizontal line. Following that reflection, the image can be put into place by an appropriate translation. One such pair of transformations is ...

Answer:

The year in which there are 30 m² of agricultural land available for each inhabitant is approximately 438.286 years

Step-by-step explanation:

The growth rate of the planet Magrathea = Double every 40 years

The start population of Magrathea = 20 million

The area of the Magrathea = 200 million km²

The area that can hose 200 Magratheans = 1 km²

The land used for agriculture = The land not used for housing

The equation for a population that doubles every 20 years is given as follows;

[tex]y = a \cdot b^t[/tex]

[tex]y = a \cdot (1 + r)^{t}[/tex]

We have;

[tex]2 = (1 + r)^{40}[/tex]

㏑2 = 40·㏑(1 + r)

㏑(1 + r) = ㏑(2)/40

1 + r = ㏑(2)/40

1 + r = e^(㏑(2)/40)

r = 1 - e^(㏑(2)/40) = 0.0174796921

30 m²

200·x

The area per individual = (1/200) km²

The total number  

We have;

(x/200) km²) + (x × 0.00003 km²) = 200,000,000 km²

x × ((1/200) km² + 0.00003 km²) = 200,000,000 km²

x = 200,000,000 km²/(((1/200) km² + 0.00003 km²)) = 3.97614314 × 10¹⁰

The population at the time = 3.97614314 × 10¹⁰

We have;

3.97614314 × 10¹⁰/(2×10⁷) = [tex]e^{(ln(2)/40)}^{t}[/tex]

t = ㏑((3.97614314 × 10¹⁰/(2×10⁷)))/(㏑[tex]e^{(ln(2)/40)}[/tex])) ≈ 438.286 years

The year in which there are 30 m² of agricultural land available for each inhabitant ≈ 438.286 years

The equation for [tex]30\,\frac{m^{2}}{hab}[/tex] is [tex]30\times 10^{-6} = \frac{10}{2^{\frac{t}{40} }}-\frac{1}{200}[/tex], whose solution is [tex]t \approx 438.28\,yr[/tex].

Dimensionally speaking, the given available area per capita for agricultural use ([tex]r[/tex]), in square kilometers per habitant, is defined by the following formula:

[tex]r = \frac{A_{T}-A_{p}}{n}[/tex] (1)

Where:

The populated area is defined by this formula:

[tex]A_{p} = m\cdot n[/tex] (2)

Where [tex]m[/tex] is the populated area per capita, in square kilometers per habitant.

By (2) in (1):

[tex]r = \frac{A_{T}}{n}-m[/tex] (1b)

And the population as function of time can be modeled after this geometric progression:

[tex]n = p_{o}\cdot 2^{\frac{t}{\tau} }[/tex] (3)

Where:

By (3) in (1b):

[tex]r = \frac{A_{T}}{p_{o}\cdot 2^{\frac{t}{\tau} }} -m[/tex] (1c)

If we know that [tex]p_{o} = 20\times 10^{6}[/tex], [tex]\tau = 20\,yr[/tex], [tex]A_{T} = 200\times 10^{6}[/tex], [tex]m = \frac{1}{200}\,km^{2}[/tex] and [tex]r = 30\times 10^{-6}\,km^{2}[/tex], then the time is:

[tex]30\times 10^{-6}\,km^{2} = \frac{200\times 10^{6}\,km^{2}}{(20\times 10^{6})\cdot 2^{\frac{t}{40\,yr} }} - \frac{1}{200}\,km^{2}[/tex]

[tex]30\times 10^{-6} = \frac{10}{2^{\frac{t}{40} }}-\frac{1}{200}[/tex]

[tex](5.03\times 10^{-3})\cdot 2^{\frac{t}{40} } = 10[/tex]

[tex]2^{\frac{t}{40} } = 1988.072[/tex]

[tex]\frac{t}{40} \cdot \log_{2} 2 = \log_{2} 1988.072[/tex]

[tex]\frac{t}{40} \approx 10.957[/tex]

[tex]t \approx 438.28\,yr[/tex]

The equation for [tex]30\,\frac{m^{2}}{hab}[/tex] is [tex]30\times 10^{-6} = \frac{10}{2^{\frac{t}{40} }}-\frac{1}{200}[/tex], whose solution is [tex]t \approx 438.28\,yr[/tex]. [tex]\blacksquare[/tex]
