What is the probability of choosing a card that does not have a digit 1 on it? Give the answer as a fraction numbers: 1,2,3,4,5,6,7,8,9,10

Answers

Final answer:

The probability of selecting a number, from the set {1,2,3,4,5,6,7,8,9,10}, that does not have the digit '1' on it, is 9 out of 10, or 9/10. Each selection is an independent event.

Explanation:

The subject of this question is Probability, a branch of Mathematics. Given the numbers 1,2,3,4,5,6,7,8,9,10, we have ten numbers in total, and only one of these numbers (1) is what we're trying to avoid. Hence, the probability of choosing a number that does not have the digit 1 on it is 9 (total numbers) - 1 (digit 1) divided by 10 total numbers, giving us a final answer of 9/10.

Probability can be represented as a fraction, where the numerator represents the favorable outcomes and the denominator represents the total number of outcomes.

Choosing each individual number is an independent event, meaning the outcome of each selection does not affect the probability of the subsequent selection.

The total number of laps needed to complete a bike marathon is 75. Kayla completed at least 68 laps. How many possible complete laps could Kayla have completed. Please show work. I'm offering lots of points for this question. Thanks you guys.

Answers

well she needs to complete 75 laps to complete the race so 75 is the upper limit. She has completed at least 68 laps so the lower limit is 68. so the number of laps she could have completed could be from 68 to 75 so the number of laps (x) can be reprented by this inequallity 68 < x < 75

well, I'm not sure if this is correct, it probably isn't, and I'm sorry if it isn't, but i think kayla could have completed 75 laps because there was only 75 laps in the race.

Suppose that you want to model the height of a rider on a Ferris wheel as a function of time. The amplitude of the function you use as a model should be equal to which of the following?a. the area of the Ferris wheel
b. the circumference of the Ferris wheel
c. the diameter of the Ferris wheel
d. the radius of the Ferris wheel

Answers

Answer: d. the radius of the Ferris wheel

Step-by-step explanation:

We now that the amplitude is the vertical distance between a peak or a valley and the equilibrium point.

Thus in the case of Ferris wheel the amplitude should be the difference between the peak(highest) and equilibrium point or equillibrium point and valley(lowest) points .

i.e. it should be half of the diameter of the circle. Since half of diameter of a circle is equals to radius.

Therefore, the amplitude of the function you use as a model should be equal to the radius of the Ferris wheel.

The amplitude of the function you use as a model should be equal to d. the radius of the Ferris wheel. The amplitude should be half the difference between the highest (maximum) and lowest (minimum) points which is half of the diameter of the circle. It is known that half of the diameter is the radius of a circle.
