Complete Question

In general,_______ % of the values in a data set lie at or below the 16th percentile.

_________ % of the values in a data set lie at or above the 24th percentile.

If a sample consists of 800 test scores, _______ of them would be at or below the 86th percentile. If a sample consists of 800 test scores,_______ of them would be at or above the 14th percentile.

Answer:

In general, 16 % of the values in a data set lie at or below the 16th percentile.

24 % of the values in a data set lie at or above the 24th percentile.

If a sample consists of 800 test scores,  688 of them would be at or below the 86th percentile. If a sample consists of 800 test scores, 688 of them would be at or above the 14th percentile.

Step-by-step explanation:

Generally percentile defines the percentage of a data set that is below or at a value that is being considered.

Hence the percentage of the values of a data set that lies below or at the 16th percentile is  16%

Also  the values of a data set that lies below or at the 24th percentile is  24%

Given a sample of 800 test scores , the number number of test scores that will be at or below the 86th percentile is 86% of  800 which is mathematically represented as

      [tex]k = \frac{86}{100} * 800[/tex]

        [tex]k = 6 88[/tex] test scores

Given a sample of 800 test scores , the number number of test scores that will be above  the 14th percentile is (100 - 14 = 86 )% of  800 which is mathematically represented as

       [tex]a = \frac{86}{100} * 800[/tex]

        [tex]a = 6 88[/tex] test scores

Answer:

(3,-1)

Step-by-step explanation:

this is because you have to use the equation [tex]y=-1x+2[/tex] which will bring you from (4,-2) to (3,-1)

Answer:

1.) y= 6x+5

2.) y= -1/3x+1

Step-by-step explanation:

Slope Intercept Form is y=mx+b,

where slope is m

the y-intercept is b

So I just plugged in the slope and y-int to get the equation

Answer:

40

Step-by-step explanation:

The sample answer for edmentum is: The first factor of the mass of an average grain of rock salt is 40 times the first factor of the mass of an average grain of table salt. So, the mass of an average grain of rock salt is 40 times greater than the mass of an average grain of table salt.

The mass of an average grain of rock sand is 43.4 times larger than the mass of an average grain of table salt

Scale factor is used to compare the size of two objects. Mathematically, we can write -

{K} = S{O1}/S{O2}

13 mg

Given is to compare the mass of an average grain of rock sand than the mass of an average grain of table salt​.

The mass of an average grain of rock sand is : 13 mg

The mass of an average grain of table salt is : 0.3 mg

So, we can write that -

{K} = M{rock sand}/M{table salt}

{K} = 13/0.3

{K} = 130/3

{K} = 43.4

So, it can be concluded that the mass of an average grain of rock sand is 43.4 times larger than the mass of an average grain of table salt.

Therefore, the mass of an average grain of rock sand is 43.4 times larger than the mass of an average grain of table salt.

Answer:

6.75 grams

Step-by-step explanation:

Total amount of lemonade with Samantha =  4 1/2 gallons

         = (4*2 + 1)/2 gallons = 9/2 gallons = 4.5 gallons

Amount of fat in 1 gallon of lemonade = 1.5 grams

To find amount of fat in 4.5 gallons lemonade

we multiply both side of equation with 4.5

Amount of fat in 1*4.5 gallon of lemonade = 1.5*4.5  grams = 6.75 grams

Thus,

there is  6.75 grams of fat in  all the lemonade Samantha has for the party
