The manager of an industrial plant is planning to buy a new machine. For each day’s operation, the number of repairs X, that the

I believe the answer is D. Town A exhibits symmetry, meaning if folded down the middle, both halves would align. Conversely, Town B displays a positive skew, indicating one or more data points skewed to the right.

B. 5 Step-by-step explanation: The greatest common factor of 85 and 15 is 5, leading to a ratio of red to white tulips of 17:3. Red tulip ratio becomes 85/5 = 17, while white tulip ratio turns out to be 15/5 = 3.

4 socks equal 1 pair of jeans
2 pairs of jeans equal 3 pairs of shoes
6 pairs of shoes equal 1 coat

Since 1 pair of jeans equals 4 socks, 2 jeans amount to 8 socks.
That means 8 socks correspond to 3 shoes.
If 3 shoes equal 8 socks, then 6 shoes would equal 16 socks.
Therefore, 16 socks are equivalent to 1 coat.
By this logic, 64 socks would translate to 64 divided by 16, which equals 4 coats.

Answer:

The anticipated number of tests required to identify 680 acceptable circuits is 907.

Step-by-step explanation:

For any circuit, there are two potential results: it either passes the test or it fails. The likelihood of passing is independent between circuits. Therefore, we apply the binomial probability distribution to address this scenario.

Binomial probability distribution

This distribution calculates the chance of obtaining exactly x successes across n trials, where x has only two possible outcomes.

To find the expected number of trials to achieve r successes with a probability p, the formula is given by:

Circuits from a specific factory pass a certain quality evaluation with a probability of 0.75.

Thus, to determine the expected number of tests needed for 680 acceptable circuits, let’s denote this as E where r = 680.

The expected number of tests necessary to find 680 acceptable circuits is 907.
