Answer:
99.9973 %
Step-by-step explanation:
This is a binomial probability distribution.
Since the probability of satisfactory welds = 97% = 0.97 and the probability of defective welds = 3% = 0.03.
Since there are 3 welds and we require at least one being defective, our binomial probability is
P(x ≥ 1) = 1 - P(x ≤ 0) = 1 - P(0) = 1 - ³C₀(0.03)³(0.97)⁰ = 1 - 1 × 0.000027 × 1 = 1 - 0.000027 = 0.999973 × 100% = 99.9973%
The answer would be the first one
The probabilities of each number are equal. Then statements A and C are correct.
<h3>What is probability?</h3>
Probability means possibility. It deals with the occurrence of a random event. The value of probability can only be from 0 to 1. Its basic meaning is something is likely to happen. It is the ratio of the favorable event to the total number of events.
Given
Pedro has a spinner with 4 sections numbered 1 through 4.
Pedro spins the spinner 100 times and records the results.
He calculates the relative frequency of each outcome.
Outcome 1 2 3 4
Relative Frequency 0.24 0.25 0.26 0.25
A) A uniform probability model is a good model to represent probabilities related to the numbers generated in Pedro's experiment. This statement is correct.
B) The theoretical probability that any one number is chosen is likely 0.20. This is incorrect because every number has an equal probability.
C) It is likely that the spinner is fair. This statement is correct because the probabilities of each number are equal.
D) The relative frequencies in the table are very different. This statement is incorrect. Because numbers 2 and 4 have the same frequency and the number 1 and 3 have slightly different frequencies.

The value of y would be C) 38 degrees because if the floor and the top of the stair are parallel, then that makes the diagonal line a transversal, therefore the 38 degree angle and y are alternate interior angles.
Answer:
{s | s < -8 or s >= -2}
Step-by-step explanation:
In order to solve an inequality we simply have to isolate the variable by applying the opposite operations on each side.
s - 2 < -10 ... add 2 to both sides
s < -8
-3s <= 6 ... divide both sides by -3, since we are dividing a negative number you must flip the sign
x >= -2
Therefore the final answer would be {s | s < -8 or s >= -2} which is the 3rd graphed multiple choice answer as seen attached to this answer.
