2.(5, 7); y =1/3x + 2

3.(3, -6); x + y = -4

4.(-9, 3); 3x + y = 5

5.(-8, 3); y+4 = -2/3 (x - 2)

Answer from: Quest

percentage - 25%

probability - 0.25

we know,

total amount of students in class = 20

total boys = 10

total girls = 10

no of girls who wear glasses = 10/2 = 5

probability of choosing a girl with glasses is =

number of girls wearing glasses/total number of students in the class = 5/20

thus, percentage of selecting a girl wearing glasses will be

= 5/20 × 100

= 5 × 5

25%

therefore,

probability will be 0.25

Answer from: Quest

"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:

75% of the temperatures are below what value? how do you know? 75% of the temperatures are above w

Answer from: Quest

Hello!

the answer is:

the correct option is the option b.

$surfacearea=126\pi units^{2}$

why?

to calculate the surface area of the right cylinder, we need to use the following formula:

$surfacearea=2\pi rh+\pi r^{2}$

from the picture we know that:

$h=2units\\r=7units$

so, substituting and calculting we have:

$surfacearea=2\pi rh+\pi r^{2}surfacearea=2*\pi *7*2+2*\pi *7^{2}=28\pi + 98\pi =126\pi units^{2}$

hence, we have that the correct option is the option b.

$surfacearea=126\pi units^{2}$

have a nice day!
