If Genry worked for 6 consecutive days and earned an average wage of $144 per day as a freelance handyman. Genry earned $142 on the last day.

Total amount  earned for the first 3 days =$132 × 3

Total amount  earned for the first 3 days = $396

Total amount he earned for the next 2 days =$163 ×2

Total amount he earned for the next 2 days = $326

Total amount he earned for all 6 days = $144 x 6

Total amount he earned for all 6 days = $864

Now let find the amount Genry earned on the last day

Amount earned = $864 - $396 - $326

Amount earned = $142

For given data , the equation of the regression line is:

y = 2.03 ln(x) - 0.205

Consider given data.

x  1 |  2   |   3   |  4    |   5        

y  1 | 21  | 121 | 621 | 3121

We need to find the equation of the regression line, if the given data linearized using logarithms.

Now we find the logarithms of y-values.

log(1) = 0

log(21) = 1.322

log(121) = 2.0828

log(621) = 2.7931

log(3121) = 3.4943

So, we get coordinates of the points: (1, 0), (2, 1.322), (3, 2.0828), (4, 2.7931), (5, 3.4943)

from the graph of given data, the equation of the regression line is:

Answer: The relationship between salary per week (s), number of weeks worked (w), and total income (t) is t = s * w.

Where t is the total income, s is the salary per week, and w is the number of weeks worked.

In Robert's case, s = $300, the equation would be t = $300 * w, where w is the number of weeks worked.

This equation shows that the total income (t) is directly proportional to the number of weeks worked (w) and the salary per week (s)

So, if Robert earns $300 every week, this equation would be t = $300 * w

Two congruent right triangles are formed by the tangents and the line connecting P to the circle's centre. They are congruent because one of the pairs of matching sides in each of those two triangles is represented by the tangent segments from P to the sites of tangency with the circle.

The kite-shaped quadrilateral that is created by the two radii and the two tangents has two pairs of adjacent sides.

The radii, the tangents, and the line from P to the centre of the circle combine to form two congruent right triangles. The tangent segments from P to the sites of tangency with the circle are congruent because they represent one of the pairs of corresponding sides in each of those two triangles.The two radii and the two tangents combine to form a quadrilateral with two pairs of adjacent sides, which is why it is a kite.

Lines that cross a circle at a single point are known as tangents.  Where the tangent crosses the radius of the circle, it is perpendicular to the tangent. Any curved shape can take into account tangent. Since the tangent is a straight line, its equation will take the form y = m x+ c .

The required linear model is y = 3968.75x + 63,500 that represents the amount of fuel on the plane (as y), in gallons, as a function of the flight time(as x), in hours.

A linear function is defined as an equation in which the highest exponent of the variable is always one.

The graph is given in the question, as shown

Let y be represents the amount of fuel on the plane, in gallons,

And x represents the function of the flight time, in hours.

As per the given graph, we take two points (0, 63,500) and (16, 0)

y - 63,500 = [(0-63,500)/(16-0)](x-0)

y - 63,500 = (63,500/16)x

y - 63,500 = 3968.75x

y = 3968.75x + 63,500

The relationship between the number of cages cleaned and the time it takes, taken as a proportional relationship, indicates that we get;

Cages cleaned = k × Minutes

Where;

k = The constant of proportionality

k = Cages cleaned ÷ Minutes

The number of cages cleaned in 15 minutes = 2 cages, therefore;

k = 2 ÷ 15 = 2/15

The number of cages cleaned in 30 minutes is therefore;

The predicted sales for the week 6 is 746.

By applying a linear equation to the observed data, linear regression aims to demonstrate the link between two variables. According to the theory, one variable should be an independent variable and the other should be a dependent variable. For instance, the relationship between a person's weight and height is linear. As a result, this demonstrates a linear relationship between an individual's height and weight. The weight of the individual increases along with their height.

We can determine the intercept and slope values for the regression model in the instance of linear regression using an Excel method.

The equation is created from the aforementioned facts.

Forecast = A + B(x)

Where A is the intercept of the data, B is the slope, and x is the period.

Intercept = INTERCEPT ( RangeY, RangeX )

Slope = SLOPE (RangeY, Range X)

Now the data corresponds to an intercept value of 698 and a slope of 8.

Therefore, for period 6, x = 6

The equation = 698 + (8 * 6) = 746

The probability that the sample mean nicotine content is less than 0.77 is approximately 0.0003.

The probability that the sample mean nicotine content will be less than 0.79 can be found by using the Central Limit Theorem. The Central Limit Theorem states that the distribution of the sample means approaches a normal distribution as the sample size increases. Since the sample size is 100, we can assume that the sample means nicotine content is approximately normally distributed.

The mean of the sample means nicotine content is equal to the population means, which is 0.8 mg. The standard deviation of the sample means nicotine content is equal to the population standard deviation divided by the square root of the sample size. So, the standard deviation of the sample means nicotine content is 0.1 mg/sqrt (100) = 0.01 mg.

Using these values, we can find the probability that the sample mean nicotine content is less than 0.79 by using the standard normal distribution table or calculator.

z = (0.79 - 0.8) / 0.01 = -1

Using a standard normal table or calculator, P(z < -1) = 0.1587.

So, the probability that the sample mean nicotine content is less than 0.79 is approximately 0.1587.

Similarly, for the sample mean nicotine content less than 0.77

z = (0.77 - 0.8) / 0.01 = -3

P(z < -3) = 0.0003

So, the probability that the sample mean nicotine content is less than 0.77 is approximately 0.0003

Answer:

Step-by-step explanation:

A five-digit palindromic number is a number that has 5 digits and is the same when read forwards and backwards. A multiple of 45 is a number that is divisible by 45.

To find the largest five-digit palindromic number that is a multiple of 45, we need to find the largest five-digit palindrome and then find the largest multiple of 45 that is less than or equal to that palindrome.

The largest five-digit palindrome is 99999. The largest multiple of 45 less than or equal to 99999 is 99945.

To find the smallest five-digit palindromic number that is a multiple of 45, we need to find the smallest five-digit palindrome and then find the smallest multiple of 45 that is greater than or equal to that palindrome.

The smallest five-digit palindrome is 10001. The smallest multiple of 45 greater than or equal to 10001 is 10035.

To find the difference between the largest and smallest five-digit palindromic numbers that are both multiples of 45, we can subtract the smallest from the largest:

99945 - 10035 = 8910

So the difference between the largest and smallest five-digit palindromic numbers that are both multiples of 45 is 8910.

The negative z-score = -0.84 and the Positive Z-score = 0.84.

The standard normal distribution is a normal distribution with a mean of 0 and a standard deviation of 1. The shaded region in the question is symmetric about z = 0 and forms the middle part of the distribution.

Standard deviation is a measure of the spread or dispersion of a set of data. It tells us how much the individual observations in a dataset vary from the mean of the dataset.

The formula for the standard deviation of a dataset is:

σ = √( Σ (x_i - μ)^2 / n)

The middle shaded region is known as the central region, it represents the middle part of the distribution, and it covers the area between two Z-scores, one negative and one positive. The area of the central region is typically given as a percentage.

For example, if the shaded region represents 68% of the total area under the standard normal distribution curve, then the two Z-scores that form the boundaries of the shaded region are the Z-scores that correspond to the 16th and 84th percentiles of the standard normal distribution. These Z-scores are -0.84 and 0.84 respectively.

Using the Bernoulli's laws to use the conserved energy

Solve the speed and the radio of this speed of the tank is open to the air

p₀ + ρgh₀ + ½ρv₀² = p₁ + ρgh₁ + ½ρv₁²

v² = 25.68  m²/s²

v1 = 5.06 m/s

Because it is open the cylinder tank so P=0 pa so:

0 Pa + 1000kg/m³ * 9.8m/s² * 0.800m + 0 = 0 + 0 + ½ * 1000kg/m³ * v²

v² = 15.68  m²/s²

v2 = 3.96 m/s

The ratio on the air is solve using both velocities so:

R = v1/v2 = 5.06 m/s / 3.96 m/s

R = 1.27

Now to find the time it takes for the tank to drain if the tank is open to the air

If for any reason my answer is wrong, feel free to correct me.

As per your question,

The airplanes accelerate uniformly at 2.7 meters per second^2

And they must reach a ground velocity of 64 m/s.

Therefore

S(Displacement) = u(initial velocity) x time + 1/2(acceleration x time^2)

Initial Velocity = 0 m/s(airplane is at rest)
Acceleration is 2.7m/s^2
Time = ?

Acceleration = Final Velocity - Initial Velocity / Time(t)

2.7 m/s^2 = 64 m/s - 0 m/s / t

2.7(t) = 64
t = 64/2.7

t = 23.703703...   rounded to 23.7

S = 0(23.7) + 1/2[2.7 x (23.7)^2]

S = 1/2(2.7 x 561.7)               561.69 is the original answer rounded to 561.7

S = 758.295 meters

Final Answer - An airport would require a runway of minimum length of 758.295 meters to accommodate aircraft of the respective specifications.

2.7 m/s^2 = 64 m/s 0 m/s/t

2.7(t) = 64

t = 64 ÷ 2,7

t = 23.703

or => 23,7

S = 0×(23.7) + 1/2[2,7 × (23,7)²]

S= 1/2(2.7 × 561.7)

S = 758.295 meters

[tex]\left|\begin{array}{rrr}i & j & k \\1 & 3 & 3 \\-3 & 3 & 0\end{array}\right|[/tex]

= i(0-9) - j(0+9) + k (3+9)

= -9i - 9j + 12k

= < -9, -9, 12>

(a*b)*c

[tex]\left|\begin{array}{ccc}4 & j & k \\-9 & -9 & 12 \\0 & 0 & -3\end{array}\right|[/tex]

= i(27-0) - j(27-0) + k (0-0)

= 27i - 27j + 0k

= < 27, -27, 0>
