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

A student measures the length of a glass rod five times and records the data as: a. 23.487 cm b. 23.493 cm c. 23.516 cm d. 23.50

MAVERICK [17]

Percent error is calculated by the expression:

%error = |actual value - observed value| / actual value x 100

We calculate the error of the values as follows:

a. 23.487 cm
% error = |23.490 - 23.487| / 23.490 x 100 = 0.013%

b. 23.493 cm
% error = |23.490 - 23.493| / 23.490 x 100 = 0.013%

c. 23.516 cm
% error = |23.490 - 23.516| / 23.490 x 100 = 0.11%

d. 23.501 cm
% error = |23.490 - 23.501| / 23.490 x 100 = 0.05%

e. 23.477 cm
% error = |23.490 - 23.477| / 23.490 x 100 = 0.055%

Choose a plant or animal that you think is interesting. describe some of the threats or challenges

Natasha_Volkova [10]

Answer:

If I were to choose a plant or animal which is interesting, I'd choose the "cactus."

Explanation:

A "cactus" is truly a splendid plant owing to its ability to survive in the desert or periods of drought. Growing them is also not that challenging or difficult. However, this plant is prone to certain threats that may lead to its extinction.

One of these threats is the "over-collection of cacti." Due to its versatile use, the cactus is often sold as an ornamental plant.
Another threat is the number of pests, such as snails and slugs, that attacks it yearly. It is a delicious food for mealy bugs, red spider mites, gnats, flies, etc.
People often misunderstand the cactus' water level needs. Some people over-water the plant and this often results to the bacteria, virus and fungi being attracted to it.
