Step-by-step explanation:

By expression, x - y = x' - y' , Distance of 3rd and 4th obstacle is equal to distance of 7th and 9th obstacle.

Distance is a numerical measurement of how far apart objects or points are, it is the length along a line or line segment between two points on the line or line segment.

Given,

The distance between obstacle three and obstacle seven is the same as the distance between obstacle four and obstacle nine.

Distance of 7th obstacle = x

Let,

Distance of 9th obstacle = y

Distance of 3rd obstacle = x'

Distance of 4th obstacle = y'

Distance between obstacle 3 and 7 = x - x'

Distance between obstacle 4 and 9 = y - y'

Distance between obstacle three and obstacle four = x' - y'

Distance between obstacle seven and obstacle nine.= x - y

According to the question

x-x' = y-y'

⇒ x - y = x' - y'

Hence, Distance between third and fourth obstacle is same as distance between 7th and 9th obstacle.

For the given width length ratio and perimeter of rectangle, the length of rectangle is 80 cm.

The perimeter of a shape is defined as the total length of its boundary. The perimeter of a shape is determined by adding the length of all the sides and edges enclosing the shape.

Let the width of the rectangle be 3x, and the length be 4x (since the ratio of the width to the length is 3:4).

The perimeter of a rectangle is the sum of the lengths of all four sides, so we have:

Perimeter = 2(length + width)

Substituting the expressions for the length and width, we get:

280cm = 2(4x + 3x)

Simplifying the right-hand side, we get:

280cm = 14x

Dividing both sides by 14, we get:

x = 20

Therefore, the length of the rectangle is 4x = 4(20) = 80 cm

C. The circumference of a circle with a radius of 1.2 mm is 7.54 mm.

D. The circumference of a circle with a radius of 9.01 cm is 56.76 cm.

The circumference of a circle is the distance around its edge. It can be calculated using the formula 2πr, where r is the radius of the circle. The radius is the distance from the center of the circle to any point on its edge. To find the circumference of a circle, we need to multiply the radius by 2 and then by pi (π), which is roughly 3.14.

For example, if the radius of the circle is 10 cm, then the circumference of the circle is 2πr = 2π x 10 cm = 62.83 cm. Similarly, if the radius of the circle is 2.7 cm, then the circumference of the circle is 2π x 2.7 cm = 16.94 cm. If the radius of the circle is 1.2 mm, then the circumference of the circle is 2π x 1.2 mm = 7.54 mm. Finally, if the radius of the circle is 9.01 cm, then the circumference of the circle is 2π x 9.01 cm = 56.76 cm.

The coordinates of the fourth vertex of the parallelogram are (1, -3).

A parallelogram is defined as a special type of quadrilateral that has both pairs of opposite sides parallel and equal.

Three vertices are located at these coordinates: (-1, 2), (1, 2), and (-1,-3).

we have three points in the coordinate plane, we can use the concept of vector addition to find the fourth point.

The vectors connecting the first and second points, and the first and third points can be determined as follows:

v₁ = (1,2) - (-1,2) = (2,0)

v₂ = (-1,-3) - (-1,2) = (0,-5)

The fourth point will be located at the vector sum of the first point and the vector formed by adding v₁ and v₂.

v₃ = v₁ + v₂ = (2,0) + (0,-5) = (2,-5)

So, the fourth point will be located at:

(-1,2) + (2,-5) = (1,-3)

For the given equation which shows the relation of temperature in Celsius and Fahrenheit, the correct option is Option D.

What is meant by temperature?

Indicating the direction in which heat energy will naturally flow from a hotter body (one with a higher temperature) to a colder body(one at a lower temperature), the temperature is a measure of hotness or coldness defined in terms of any of several arbitrary scales.

The given equation is:

[tex]C = \frac{5}{9} (F- 32)[/tex]

where C = temperature in Celsius

          F = temperature in Fahrenheit

The above equation can be rewritten as:

C = 5/9F - 160/9

Now, this is an equation of a straight line with a formula,

y = mx + c

Comparing,

m = 5/9 which is the slope of the equation.

This means that for a temperature increase of 1 degree Fahrenheit, the equivalent increase in temperature in Celsius is 5/9.

So the option I is true.

Similarly, an increase in 1 degree Celsius of temperature is equivalent to 9/5 = 1.8 degree increase in Fahrenheit.

So option II is true.

Option III is not true as is discussed above.

Therefore for the given equation of temperature, the correct option is Option D.

The rate at which the water level is rising when the water level is 2 cm is 8 cm.

A pyramid's volume is equal to 1/3 of B, where B is the base's area and h is its height. Given that the base is square, B = s2, where s is a base side The volume is therefore 1/3 s2h.

We are aware that the base's side is 8 cm long and the whole pyramid's height is 11 cm. Also, no matter how high the water is, its surface will always form a square with the same proportion to the water's depth as a side of the pyramid's top has to the pyramid's total height. This indicates that s = 8/11 h regardless of the water depth.

So that means that the formula for the volume of the pyramid formed by the water is V = 1/3 (8/11 h)2 h = 64/363 h3.

Separate this as a function of time to get the rate of change of the volume of water :

V = 64/363 h3

dV/dt = 3 (64/363) h2 dh/dt = 192/363 h2 dh/dt

Nonetheless, we are aware that the volume is shifting at a speed of 65 cc every second.  So at any point in time,

65 = 192/363 h2 dh/dt

65 * 363 / 192 = h2 dh/dt

23595 / 192 = h2 dh/dt

(23595 / 192) / h2 = dh/dt

When the level of water (h) is 8, that indicates:

(23595 / 192) / 64 = dh/dt

1.92 = dh/dt

So the water level is rising at the rate of 1.92 cm per second when the water level is 8 cm.

2 trapezoids compose a hexagon using equal-size shapes: 2 trapezoids, 6 triangles, or 3 blue rhombuses. compose hexagons using different shapes. So 2 trapezoids create 1 hexagon. This means 6 trapezoids make 3 hexagons.

The exact number of trapezoids needed to create three hexagons depends on the size and shape of the hexagons.

However, in general, you would need at least 18 trapezoids.

An hexagon is a six-sided polygon. It is made up of six equilateral triangles and six trapezoids.

If you are looking to create larger hexagons you will need more trapezoids.

Depending on the size and shape, you could need as many as 24 or more trapezoids.

The probability that at most four of the M&M are yellow is  0.3357 and the probability that at least two of the four of the M & M are yellow is   0.6622

The probability that at most two of the four M&M's are yellow can be calculated using the cumulative distribution function (CDF) of the binomial distribution. The binomial distribution models the number of successes in a fixed number of independent Bernoulli trials, where each trial has the same probability of success. In this case, the number of trials is 4, and the probability of success (getting a yellow M&M) is 0.13.

The cumulative distribution function of the binomial distribution can be expressed as:

P(X <= k) = SUM[i=0 to k] (n choose i) * p^i * (1-p)^(n-i)

Where n is the number of trials, k is the value we want to find the probability for, p is the probability of success, and (n choose i) is the number of combinations of n items taken i at a time, which can be calculated as n! / (i! * (n-i)!).

For this problem, we want to find the sum of probabilities for X = 0, 1, and 2, so we have:

P(X <= 2) = P(X = 0) + P(X = 1) + P(X = 2)

= (4 C 0) * (0.13)^0 * (0.87)^4 + (4 C 1) * (0.13)^1 * (0.87)^3 + (4 C 2) * (0.13)^2 * (0.87)^2

= 0.3357

NB: "C" represent combination.

So the probability that at most two of the four M&M's are yellow is approximately 0.3357.

b. The probability that at least two of the four M&M's are yellow can be found by subtracting the probability of getting 0 or 1 yellow M&M's from 1. So:

P(X >= 2) = 1 - P(X <= 1)

= 1 - (P(X = 0) + P(X = 1))

= 1 - ((4 C 0) * (0.13)^0 * (0.87)^4 + (4 C1) * (0.13)^1 * (0.87)^3)

= 0.6622

So the probability that at least two of the four M&M's are yellow is approximately 0.6622.

The mean of the distribution is given by n * p = 4 * 0.13 = 0.52, and the standard deviation is given by sqrt(n * p * (1-p)) = sqrt(4 * 0.13 * 0.87) = 0.9304.

a) The simple interest that will be owed the bank by Diane after 76 days is $343.59.

b) The final amount that Diane will repay the bank after 76 days is $17,443.59.

The simple interest is an interest system that does not compound interest.

Compounding interest means that interest is added to the principal before subsequent interests are computed.

But under the simple interest system, interest is based on the principal from one period to the next.

The loan amount = $17,100

Simple interest rate = 9.65%

Loan period = 76 days

Total interest = $17,100 x 9.65% x 76/365 = $343.59
