inn [45]

The answer to the first unknown in the problem is the "Areolar" while in the second unknown in the problem is the "Cartilage". Hence, to complete the given statement in the problem, we have an example of a high vascular tissue is "AREOLAR" tissue and as an example also of a tissue that is not highly vascular is the "CARTILAGE".

Determine the median value for foot width for males and for females. Describe in complete sentences the method you used to deter

Ipatiy [6.2K]

Answer:

This question is incomplete because of the absence of the data referred to in the question

Explanation:

This question is incomplete but the data referred to in the question is attached below

In order to determine the median value of any set of data, the data is first of all rearranged chronologically (ascending) and then the middle value is picked if the number of data is odd but if the number of data is even, the two middle values are added together and then divided by two to get the median.

From the data provided, the values (which are 10 in number) can be arranged as shown below (with the median values in bold)

Females: 5, 7, 7, 7.5, 7.5, 7.8, 7.8, 8, 8, 17

Males: 4.5, 7.5, 9, 9, 9.2, 9.3, 10, 10, 10.5, 13

Since the number of data is even, the two middle numbers (in bold) shall be added together and then divided to get the median as shown below

The median value for the females foot width is = 7.5 + 7.8/2 = 7.65 cm

The median value for the male foot width is = 9.2 + 9.3/2 = 9.25 cm

In many states, the legal limit for all bacteria present in pasteurized milk is not to exceed 20,000 CFU/mL. You have been away

zaharov [31]

Answer:

a. The formula for finding the number of colonies in a given volume is,

CFU/ml, here CFU is the colony forming units or the number of colonies formed in a volume plated in ml × dilution

The dilution factor given in the question is 1 × 10⁻⁴ and the number of colonies given is 186. Therefore, the number of bacteria present in the given 1 ml of the milk is,

CFU/ ml = 186 / 1 × 10⁻⁴ = 186 × 10⁴.

Hence, the concentration of bacteria in the milk is 186 × 10⁴ CFU/ml.

b) The limit of the bacterial concentration in the pasteurized milk is 20000 CFU/ml, however, it can be seen that the sample of the milk possess more concentration of bacteria than the desired value. Therefore, the milk is not safe to drink by Public Health Standards.
