A group of students were surveyed to find out if they like cleaning house and/or mowing lawns during the holidays. The results of the survey are shown below: 20 students like cleaning house
5 students like cleaning house but do not like mowing lawns
18 students like mowing lawns
5 students do not like cleaning house

Four students created the tables below to represent the data. CH represents cleaning house and ML represents mowing lawns.

Sam
Like CH Do Not Like CH Total
Like ML 15 3 18
Do Not Like ML 5 2 7
Total 20 5 25
Brenda
Like CH Do Not Like CH Total
Like ML 20 3 23
Do Not Like ML 5 5 10
Total 25 8 33
Cathy
Like CH Do Not Like CH Total
Like ML 3 15 18
Do Not Like ML 2 5 7
Total 5 20 25
Nathan
Like CH Do Not Like CH Total
Like ML 3 20 23
Do Not Like ML 5 5 10
Total 8 25 33

Which student's table is correct?
Sam
Brenda
Cathy
Nathan

i belive those are the ones that are under 90 degreese.

eve and marks ratios are equivalent

step-by-step explanation:

"it's not the heat, it's the humidity".   that's a partly valid phrase you may have heard in the summer, but it's actually both.   the heat index, also known as the apparent temperature, is what the temperature feels like to the human body when relative humidity is combined with the air temperature.   this has important considerations for the human body's comfort.   when the body gets too hot, it begins to perspire or sweat to cool itself off.   if the perspiration is not able to evaporate, the body cannot regulate its temperature.   evaporation is a cooling process.   when perspiration is evaporated off the body, it effectively reduces the body's temperature.   when the atmospheric moisture content (i.e. relative humidity) is high, the rate of perspiration from the body decreases.   in other words, the human body feels warmer in humid conditions.   the opposite is true when the relative humidity decreases because the rate of perspiration increases.   the body actually feels cooler in arid conditions.   there is direct relationship between the air temperature and relative humidity and the heat index, meaning as the air temperature and relative humidity increase (decrease), the heat index increases (decreases).

step-by-step explanation:

the correct option is 2.

step-by-step explanation:

according to the given information triangle abc is a right angle triangle with right angle at a. segment ab is 5 and segment ac is 7. point d is on segment bc and angles adb and adc are right angles.

it is given that triangles abd, cad, and cba are similar.

two triangles are similar if their corresponding sides are proportional.

in triangle cba, using pythagoras theorem

                      )

triangle abd and cba are similar,

                            (2)

triangle cad and cba are similar,

                      )

using (1), (2) and (3), we get

hence proved.

therefore option 2 is correct.
