The test grades for a certain class were entered into a Data Analysis worksheet, and then the following descriptive statistics were obtained. Grades : N = 32, Mean = 78.1, Median = 77.0, StDev = 10.61, Min = 38.0, Max = 96.0, Q1 = 69.0 and Q3 = 85.0 You happen to see on a piece of scrap paper that the lowest grades were 38, 58, 60, 60... but you don't know what the other individual grades are. Nevertheless, a knowledgeable user of statistics can tell a lot about the data set simply by studying the set of descriptive statistics above. Describe the shape and the spread of the distribution

answer: a. 13/44

step-by-step explanation: judging by the information given to us, we are looking for experimental probability. we can see that 13 males have chosen chocolate ice cream. there are 44 ice creams in total (remember that the total is always the denominator). so our answer is 13/44.

the answer is:

the lateral area is equal to

to find the lateral area of the square pyramid, first we need to find the perimeter of the base, and then, find the lateral area using the following formulas:

where,

s, is the base length

slant height, is the height of a the side of the pyramid

we are given:

now, calculating the perimeter of the base, we have:

then, calculating the lateral area:

hence, we have that the lateral area is equal to

have a nice day!
