Diano4ka-milaya [45]2 years ago
7 0

lemon juice is 100 times as acidic as tomato juice. remember, each step in the pH scale represents a change in concentration by a factor of 10. since tomato juice has a pH of 4.0, and lemon juice has a pH of 2.0, the concentration would change by 10 times 10.

A particular leg bone for dinosaur fossils has a mean length of 60 inches with a standard deviation of 3 inches. What is the len
stepan [7]

The average length of a specific dinosaur leg bone is 60 inches, with a standard variation of 3 inches. If a z-score is 0, then the length is 67.

Divide your data point by your standard error after taking your data point and subtracting the mean from it. How is the z-score determined? Z-scores are calculated using the formula z = (x-)/, where x represents the raw score, the population mean, & the population variation. The z-score is just the raw score less the population mean, split by the population variance, as the calculation demonstrates. You now have your Z-score. For instance, a scoring of 450 would equate a scores of (450-500)/100 (= -50/100 = -0.50 on a scale with a mean of 500 as well as a standard variation of 100, indicating that the scoring is half a variance below the mean.

What is the mean of the data set [3,2,2,12,6,5,14,4]?<br><br>A.2<br>B.4<br>C.6<br>D.7
zysi [14]

Answer:

6

Explanation:

To find the mean of a data set, add all the values in the set together, and then divide the result by the number of values in the set.

3 + 2 + 2 + 12 + 6 + 5 + 14 + 4 = 48

There are 8 values in the data set.

48/8 = 6

So the mean of the data set is 6.

Suppose that a person takes a fall while hiking and develops tetanus when the pathogen enters through an open wound in their arm
qaws [65]

The tetanus infection is considered to be a Droplet infection.

<h3>What is Tetanus?</h3>

Tetanus is a neurological disease which is characterized by the occurrence of spasms in the muscle.

Tetanus can be caused if initial care does not take place after the wound occurs and therefore, it is very important to immediately take care of the wound.

To treat the wound tetanus immunoglobulin and tetanus toxoids are given to the person, however, it is necessary to give the two injections using different syringes and at different sites, because the immunoglobulin can cause neutralization fo the toxoid.

Thus, this could be the answer.
