A simple random sample of ten people is taken from the set of all registered voters in a given district to determine their avera

It's crucial to recognize that all necessary information is already presented in the question

The likelihood of a day being hot equals 0.15 + 0.10
                                                   = 0.25
The likelihood of a day being sunny amounts to 0.15 + 0.30 + 0.10
                                                        = 0.55
Combining the two probabilities, we find = 0.25 + 0.55
                                                                     = 0.80
Now
The probability of a day being both hot and sunny is 0.15
Thus
The probability of a day being either hot or sunny = 0.80 - 0.15
                                                               = 0.65
I trust this explanation is clear enough for your understanding.

Answer: The coordinates of point T are (13, -6).

Step-by-step explanation: Given that point S is the midpoint of segment RT, with coordinates R(-9, 4) and S(2, -1),

we need to determine the coordinates of point T.

The midpoint formula states that the midpoint between points (a, b) and (c, d) is ((a + c)/2, (b + d)/2).

Let T be (h, k). According to the problem:

Solving these equations yields T at (13, -6).

So, the required coordinates for point T are (13, -6).

This question reveals an intriguing pattern.

The rule or pattern to follow here is:

For the left side of the number compared to its predecessor: (First digit x Third digit + 1)

For the right side: (Second digit x Fourth digit -1)

For instance, consider 6447. Next, let's examine its previous number, 9876.

Now, and

that's how we arrived at 6447

Next, for the third number, 2527, let's look at its previous number, 6447

Now,

and

that's how we reached 2527

Following the same reasoning, the missing number should be 534.

This conclusion came from applying the rule of the pattern as:

and

Thus, we derived 534.

5400000, since the 7 rounds the 8 up to 4.

Health inspector visits once a week.
Fire inspector comes every 12 days.

a) health inspector fire inspector.
day 7.                    day 12.   
day 14.                    day 24.
day 21.                    day 36.
day 28.                    day 48.
day 35.                    day 60.

b) 12 x 7 = 84.

Both will coincide on day 84.
