The table shows Mitch’s record for the last thirty par-3 holes he has played.
Based on this record, what is the probability that Mitch will score a 2 or 3 on the next par-3 hole?
a. 7/9
b. 3/5
c. 3/10
d. 9/50

Answer:

40 degrees

Step-by-step explanation:

the bottom angles are 70 each because you can find one of them by subtracting 110 from 180 (110 is an exterior angle to one of the bottom sides). The other is also 70 because the triangle is an isosceles. Then, subtract 70*2 from 180 to get 40 degrees for x (the remaining side).

Q and X

On a telephone dial, the letters "Q" and "Z" do not appear. The dial was designed to include commonly used letters and numbers, prioritizing efficiency and simplicity in dialing.

On a traditional telephone dial, there are two letters that do not appear:

The letter "Q" does not appear on the telephone dial. This omission is because the letter "Q" is not necessary for dialing phone numbers or for any commonly used telephone functions.

The letter "Z" is also absent from the telephone dial. This omission is because the letter "Z" is not needed for dialing phone numbers and is not commonly used in telephone-related applications.

The layout of the telephone dial was designed to accommodate the most frequently used letters and numbers while minimizing the number of keys. This design decision was made to ensure efficiency and simplicity in dialing numbers and accessing telephone services.

Answer:

y = -7x - 2

Step-by-step explanation:

use y = mx + b

y = y-coordinate = 5

m = slope = -7

x = x-coordinate = -1

b = y-intercept = the only missing piece/what we're solving

usually, for an equation, x and y stay as variables, but to find the y intercept we need to plug in the coordinates:

5 = (-7)(-1) + b                   multiply -7 and -1

5 = 7 + b                           subtract 7 from both sides

b = -2                              

plug b into the equation and leave x and y as variables:

y = -7x - 2

Answer:

B. 95%

Step-by-step explanation:

The mean is in the middle and standard deviation is 12. So subtract 12 from 98 until you get to 74. That's two times. And two times/spaces to the left and right is 95% of the data.

The confidence interval is 95.45% of the data in the data set with a normal distribution

The mean of your estimate plus and minus the range of that estimate constitutes a confidence interval. Within a specific level of confidence, this is the range of values you anticipate your estimate to fall within if you repeat the test. In statistics, confidence is another word for probability.

With a 95 percent confidence interval, you have a 5 percent chance of being wrong. With a 90 percent confidence interval, you have a 10 percent chance of being wrong. A 99 percent confidence interval would be wider than a 95 percent confidence interval

Confidence Interval CI = x + z ( s/√n )

where x = mean

z = confidence level value

s = standard deviation

n = sample size

Given data ,

To find out what percent of the data lie between 74 and 122 in a normal distribution with a mean of 98 and a standard deviation of 12, we can use the empirical rule, also known as the 68-95-99.7 rule, which states that:

Approximately 68% of the data falls within one standard deviation of the mean

Approximately 95% of the data falls within two standard deviations of the mean

Approximately 99.7% of the data falls within three standard deviations of the mean

Based on this rule, we can estimate the percentage of data that lies between 74 and 122 as follows:

Calculate the z-scores for 74 and 122 using the formula: z = (X - mean) / standard deviation

For 74: z = (74 - 98) / 12 = -2

For 122: z = (122 - 98) / 12 = 2

Find the area under the normal curve between these two z-scores using a standard normal distribution table or a statistical calculator.

The area between z = -2 and z = 2 represents the percentage of data that lies between 74 and 122.

Using a standard normal distribution table, we can find that the area between z = -2 and z = 2 is approximately 0.9545 or 95.45%.

Hence , about 95.45% of the data in the data set with a normal distribution would be expected to lie between 74 and 122.

Answer:

East Port Tier City is 11.5 hours ahead of Phoenix.

Step-by-step explanation:

Given that the city of Phoenix, Arizona is located in the UTC -7 time zone, while East Port Tier City is located at UTC +4.5, to determine the time difference between the two cities, the following calculation must be performed:

4.5 - (-7) = X

4.5 + 7 = X

11.5 = X

Thus, the time difference between Phoenix and East Port Tier City is 11.5 hours.
