In a class of 25 students, the following test scores were obtained:

marta [7]

Answer:

Step-by-step explanation:

Firstly,we need to find the mean, median and mode to enable us know the type of distribution it exhibit.

Mode-data with the highest frequency that is data that has the highest repetition which is 59.

Median-the middle data which is 75.

Mean-average of the data that is addition of the data divided by 25 which gives 75.4 approximately equals to 75

Distribution is unimodal symmetric if it has one clear peak(one mode) and mean = median , so Option A is right

Distribution is skewed left if the mean is less than median and the mode is less than the median that is mean is less than the median, and they are both less than the mode. So option B is wrong.

A distribution is uniform if all outcomes are likely to be the same,it is usually a rectangular shaped distribution. So option C is wrong

A distribution is bimodal if it has two modes. This means that there are two data values that tie for having the highest frequency but as for this data we have only one data with the highest frequency so option D is wrong

Option A is correct

I'm so sorry for the late answer!

(a) Rectangular container
There are 3 pairs of congruent sides. Each side's area can be solved by multiplying either 12, 8, or 3. Then because for each side, there is another side that is exactly the same, we can multiply by 2.
(2*12*8) + (2*12*3) + (2*8*3) = 312

(b) Surface Area of a cylinder is $2 \pi r^{2} +2 \pi rh$
We know that r is 2 and that the whole expression is equal to 312.
Plug 2 back into the equation and set it equal to 312.
$2 \pi *4+2 \pi *2h = 312 \\ 4 \pi *h = 312-8 \pi \\ h = \frac{312-8 \pi }{4 \pi } = 23$
The height of the cylinder has to be around 23 inches.
