The diagnol of the floor of the room divides it into two right triangles, were the length of the walls represents the base and height and the dignol is the hypothenuse.

Usinf Phyagoras Theorem, that states that the square of the hypothenuse is equal to the right triangle. we can calculate the heightof thr triangle as:

Step-by-step explanation:

The following moment generating function variance of the given distribution is 0.16,Mean= 0.2,Variance= 0.16.

The mean and variance from the moment generating function (MGF) to differentiate the MGF and evaluate it at t=0 to find the first and second moments.

differentiate the MGF to find the first moment (mean):

m'(t) = d/dt [0.2exp(t) + 0.8]

= 0.2exp(t)

evaluate the first derivative at t=0:

m'(0) = 0.2exp(0)

= 0.2

The first derivative at t=0 gives us the first moment (mean). Therefore, the mean of the given distribution is 0.2.

To find the variance to differentiate the MGF again:

m''(t) = d²/dt² [0.2exp(t) + 0.8]

= 0.2exp(t)

evaluate the second derivative at t=0:

m''(0) = 0.2exp(0)

= 0.2

The second derivative at t=0 gives us the second moment. The variance is equal to the second moment minus the square of the mean:

variance = m''(0) - (m'(0))²

= 0.2 - (0.2)²

= 0.2 - 0.04

= 0.16

The correct answer is (0.745  , 0.989 )

Given:

n = 30

x = 26

Point estimate = sample proportion =\(\hat P\) p = x / n = 26/30 = 0.8667

\(1 - \hat p\) = 1-0.8667 = 0.1333

a) At 95% confidence level

\(\alpha\) = 1-0.95% =1-0.95 =0.05

\(\alpha/2\) = 0.05/ 2= 0.025

\(Z\alpha/2\) =  = 1.960

\(Z\alpha/2\) = Z 0.025 = 1.960

Margin of error = E = \(Z\alpha / 2 * \sqrt((\hat p * (1 - \hat p)) / n)\)

                         \(= 1.960* (\sqrt(0.8667*(0.1333) /30 )\)

                         = 0.122

A 95% confidence interval for population proportion p is ,

\(\hat p - E < p < \hat p + E\)

0.8667-0.122 < p <0.8667+0.122

0.745  < p <  0.989

(0.745  , 0.989 )

The linear cost function can be written as C(x) = 55 + 0.45x. The correct option is D. C(x) represents the cost of using the parking garage for x half-hours.

The linear cost function for the situation described is C(x) represents the cost of using the parking garage for x half-hours. (Option D)

In the given situation, the parking garage charges a fixed amount of $55 plus an additional cost of $0.45 per half-hour. To represent this cost function as a linear equation, we can use the variable x to represent the number of half-hours the parking garage is used.

Option D correctly identifies that C(x) represents the cost for using the parking garage for x half-hours. This means that the input x in the cost function represents the number of half-hours the parking garage is used, and the output C(x) represents the corresponding cost in dollars.

Therefore, the linear cost function can be written as:

C(x) = 55 + 0.45x

Here, 55 represents the fixed cost of using the parking garage, and 0.45x represents the additional cost per half-hour multiplied by the number of half-hours used.

So, the correct option is D. C(x) represents the cost of using the parking garage for x half-hours.

Answer: You need the unit price of how much it cost per min.

Step-by-step explanation:

First you have to find how much it costs for each min. So you divive 22.40 by 32 and you will get the answer for the cost of each min. Then Multiply the cost of each min by 38 and you should get the cost for 38 min.

Answer:  x = 68/3

Step-by-step explanation: 2/3x - 1/9 + 5 = 20

Combine the fractions:   5 - 1/9 = 44/9

44/9 + ⅔x = 20

Subtract 44/9 from both sides:   44/9 + ⅔x - 44/9 = 20 - 44/9

Simplify:  ⅔x = 136/9

Multiply both sides by 3:    3 x ⅔x = 136 x 3 divided by 9

Simplify:   2x = 136/3

Divide both sides by two:   2x/2 = 136/3 divided by two

Simplify:   x =  68/3

The value of k from the equation is k = -20

The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept

And y - y₁ = m ( x - x₁ )

y = y-coordinate of second point

y₁ = y-coordinate of point one

m = slope

x = x-coordinate of second point

x₁ = x-coordinate of point one

The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )

Given data ,

Let the equation of line be represented as A

Now , the value of A is

Answer:

The number of possible triangles that can be formed is 132 triangles

Step-by-step explanation:

Given that there are 6 points in line a and 4 points on line b

Number of points on line a = 6

Number of points on line b = 4

To form a triangle, firstly we select 2 points from line a and one point from line b as follows;

Number of ways to select 2 points from 6 = ₆C₂ = 15 ways

Number of ways to select 1 points from 4 = ₄C₁ = 4 ways

The number of triangles = 15×4 = 60 triangles

Next we form triangles by selecting 2 points from line b and one point from line a as follows;

Number of ways to select 2 points from 4 = ₄C₂ = 12 ways

Number of ways to select 1 points from 6 = ₆C₁ = 6 ways

The number of triangles = 12×6 = 72 triangles

The total number of triangles = 72 + 60 = 132 triangles.

Answer:

Step-by-step explanation:

In general, if the sample size is large, adding an extremely large outlier to a data set will not substantially affect the mean.

A very large outlier will typically not significantly change the mean of a data set if the sample size is large. However, adding an extremely large outlier to a data set with a small sample size can have a substantial effect on the mean.

This is because the mean is heavily influenced by the values of the individual data points, and an outlier can have a disproportionately large impact on the mean if the sample size is small.

If you go twice as fast, your stopping distance will increase by four times (option C).

This relationship is based on the laws of physics and the principles of motion.

When an object is in motion, its stopping distance is influenced by its initial speed, reaction time, and braking capabilities. The stopping distance consists of two components: the thinking distance (the distance traveled during the reaction time) and the braking distance (the distance needed to bring the object to a complete stop).

According to the laws of physics, the braking distance is directly proportional to the square of the initial speed. This means that if you double your speed, the braking distance will increase by a factor of four. In other words, going twice as fast will require four times the distance to come to a stop.

It is important to note that this relationship assumes other factors, such as road conditions and braking efficiency, remain constant. However, in real-world scenarios, these factors may vary and can affect the stopping distance to some extent.

An inequality that represents the possible dimensions for the garden is ab < 80. And the three different sets of allowable dimensions for the garden are {5, 10}, {10, 5} and {6, 6} and the area  50 square feet,  50 square feet, 36 square feet respectively.

In mathematics, "inequality" refers to a relationship between two expressions or values that are not equal to each other. To solve the inequality, you may multiply or divide each side by the same positive number, add the same amount to each side, take the same amount away from each side, and more. You must flip the inequality sign if you multiply or divide either side by a negative number.

Given:

The maximum area that is available for a rectangular garden is 80 square feet.

Let a and b are the length and width of the rectangular garden.

And A be the area.

(a).

So, A < 80

That means, ab < 80.

(b).

To find the dimension of the rectangle:

We find the numbers whose product is less than 80.

Let the three number sets are,

{5, 10}, {10, 5} and {6, 6}.

(c).

So, the area of the rectangles are:

5 x 10 = 50 square feet,

10 x 5 = 50 square feet,

And 6 x 6 = 36 square feet.

Therefore, the inequality is ab < 80, three number sets are {5, 10}, {10, 5} and {6, 6} and the area  50 square feet,  50 square feet, 36 square feet respectively.
