The probability that 200 or fewer homes were purchased as investment properties is 0.937. This is calculated using the binomial distribution formula, where n = 600, p = 0.31, and x = 200.

1. The binomial distribution formula for calculating the probability of an event occurring is:

P(x) = nCx * p^x * q^(n-x)

where n is the number of trials, x is the number of successes, p is the probability of success, and q is the probability of failure (1 - p).

2. In this problem, n = 600, p = 0.31, x = 200, and q = 1 - 0.31 = 0.69.

3. Plugging these values into the formula, we get:

P(x) = 600C200 * 0.31^200 * 0.69^400

4. Solving this equation, we get P(x) = 0.937.

5. Therefore, the probability that 200 or fewer homes were purchased as investment properties is 0.937.

Josiah will take 1.5 hours to travel to work at the speed of 55 miles per hour.

As the speed and time are inversely proportional to each other, we can represent it as -

speed(i)/speed(f) = time(f)/time(i), where I represents initial and f represents final. Now, keep the values in formula to find the time (final).

35/55 = time(f)/2.5

Rewriting the equation according to variable time(f).

time(f) = (35×2.5)/55

Performing multiplication on Right Hand Side of the equation

time(f) = 87.5/55

Performing division on Right Hand Side of the equation

time(f) = 1.59 hours

The team a finishes with more points than team b with a probability of 319/512

seven teams play a soccer tournament in which each team plays every other team exactly once

in the first game of the tournament, team a beats team b

We need to find  the probability that team a finishes with more points than team b

Both teams, a and b play 6 matches each

In the first match, a wins. Now they can play 5 matches each

Of the remaining 5 games

a win 0 and b win zero

P(a > b) = 5C1/2^5 x 5C1 / 2^5 = 1/1024

a win 1 and b win 1 or zero

P(a > b) = 5C1/2^5 x(5C0 + 5C1) / 2^5 = 30/1024

a win 2  and b win 2 or 1 or zero

P(a > b) = 5C2/2^5 x(5C0 + 5C1 + 5C2) / 2^5 = 160/1024

a win 3 and b win 3 or 2 or 1 or zero

P(a > b) = 5C3/2^5 x(5C0 + 5C1 + 5C2 + 5C3) / 2^5 = 260/1024

a win 4 and b win 4 or less

P(a > b) = 5C4/2^5 x(5C0 + 5C1 + 5C2 + 5C 3 + 5C4) / 2^5 = 155/1024

P(a > b) = 5C1/2^5 x(5C0 + 5C1+ 5C2 + 5C3 + 5C4 + 5C5) / 2^5 = 32/1024

P(a> b) = (1 + 30 + 160 + 260 + 155 + 32)/1024 = 638/1025 = 319/512

Therefore, the  the probability that team a finishes with more points than team is 319/512

Step-by-step explanation:

The area of a circle is given by the formula A = πr^2, where A is the area of the circle, r is the radius of the circle, and π is a mathematical constant approximately equal to 3.14.

To find the area of a Mercedes wheel with a radius of 15 inches, we can substitute these values into the formula:

A = πr^2 = π(15 inches)^2 = 706.5 inches^2

Rounding to the nearest tenth, the area of the Mercedes wheel is approximately 706.5 inches^2.

The vertices of a regular decagon can only ever give rise to a maximum of zero scalene triangles at any one time.

Generally, An isosceles triangle has two sides with the same length. There are 10 ways to choose the vertex that is common to the two equal sides, and for each of these choices, there are 5 ways to choose the other two vertices (since they must be distinct from the first). Therefore, there are a total of

10* 5*5=250 isosceles triangles.

To get the final count of scalene triangles, we use the principle of inclusion-exclusion by subtracting the number of isosceles triangles from the total number of triangles.

This gives us a final count of 120-250=-130.

However, since we cannot have a negative number of triangles, the final answer is 0.

Therefore, there are 0 scalene triangles that can be formed from the vertices of a regular decagon.

Answer: May I see the graph?

Step-by-step explanation:

We can determine whether the rocket is ascending or descending by evaluating the derivative at that time. If the derivative is positive, the rocket is ascending. If the derivative is negative, the rocket is descending.

What is a derivative of a function?

The derivative of a function can be interpreted as the slope of the graph of the function or, more precisely, as the slope of the tangent line at a point. Its calculation, in fact, derives from the slope formula for a straight line, except that a limiting process must be used for curves.

To determine whether the rocket is ascending or descending at a given time, we need to find the derivative of the function h(t) and determine whether it is positive or negative.

The derivative of h(t) is given by h'(t) = -t²+42t+43. This is the rate of change of the height of the rocket at any given time. If the derivative is positive, the rocket is ascending. If the derivative is negative, the rocket is descending.

At t = 1 second, h'(t) = -1 + 42 + 43 = 44. Since the derivative is positive at t = 1, we know that the rocket is ascending at this time.

Hence, we can determine whether the rocket is ascending or descending by evaluating the derivative at that time. If the derivative is positive, the rocket is ascending. If the derivative is negative, the rocket is descending.
