for jimena to be accepted into her favorite college, she will have to earn an entrance exam score at least 2 standard deviations above the mean. assume entrance exam scores are normally distributed, with a mean of 790 and a standard deviation of 50. what exam score does jimena need to be accepted at her favorite college?

a. 690
b. 890
c. 740
d. 840

B. 890

Step-by-step explanation:

Given: Standard deviation= 50

           Mean= 790

As per question, Jimena will have to earn atleast 2 standard deviation above mean in the entrance exam score.

We know, one standard deviation is equal to 50, which mean 2 standard deviation=

∴ Two standard deviation= 100

Now, forming an equation for Jimena´s exam score.

Putting up the value in the equation

⇒

⇒

∴

Hence, Jimena have to earn at least 890 in the entrance exam to be accpeted at her favorite college.

"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:

(1, –1), (16, –4), (36, –6)

step-by-step explanation:

given that the function is

this can also be written as

we have to graph this function and check which list of points lie on the graph

see attachment for graph:

we find that the points lying are (1,-1) (16,-4) and (36,-6)

since square root is there we find that x can only be posiitve but y can be since square root both positive and negative.
