It would be 1/4 because

when you subtract fractions with the same denominator it is easy. you subtract the numerators.

1/4 cause you have five 1/4s so if you take four of those away then 5-4=1 therefore you only have one 1/4 so yeah

hat is the average rate of change of f(x), represented by the table of values, over the interval [-2, 3]? x f(x) -6 2.5 -2 2.5 0
vodomira [7]
Your table of values is so difficult to read that many of us helpers would just skip your post.

<span>x f(x) -6 2.5 -2 2.5 0 2 2 0 3 5 5 2.5 1 0.5</span>  could be put into far clearer format as follows:

 x   f(x)
--  -----
-6  2.5
-2  2.5
and so on.  Please fix it.

The "average rate of change" formula is 

                  f(x2) - f(x1)
av r of c = ---------------
                     x2-x1

so if you go from (-6, 2.5) to (2.5, 10.5), the av r of c would be
                  
                 10.5 - 2.5            9        18
             ------------------ = -------- = -----
                 2.5-(-6)            8.5         17

This may or may not be your final answer.  Again, please put your data table into readable form and then find the av r of c over the interval [-2,3].

Suppose 180 geology students measure the mass of an ore sample. due to human error and limitations in the reliability of the​ ba
Over [174]

Given the total number of students are 180, the mean of data is 88g, and standard deviation is 1g.

A normal curve is a bell-shaped curve with symmetry about the mean and it spreads uniformly on both sides (left side and right side) of the mean.

The empirical rule is also called "68-95-99.7" rule. It says that :-

A) 68% of the data values fall between 1 standard deviation about mean (34% on left side and 34% on right side),

B) 95% of the data values fall between 2 standard deviations about mean (47.5% on left side and 47.5% on right side), and

C) 99.7% of the data values fall between 3 standard deviations about mean (49.85% on left side and 49.85% on right side).

According to distribution of normal curve and "68-95-99.7" empirical rule, we can say 49.85% of data values are above the mean within 3 standard deviations.

So it means 49.85% of total students report readings more than 88g.

Number of students reporting readings more than 88g = 49.85% of 180 = 0.4985 × 180 = 89.73

Hence, approximately 89 students report readings more than mean value.

Type the standard form of three hundred thousand two hundred one
leonid [27]

━━━━━━━━━━━━━━━ ♡ ━━━━━━━━━━━━━━━  

Standard form is numbers only.

Examples of standard numbers are 4, 225, or 9,002

A thousands number has 4 digits.

A hundreds number has 3 digits.

A tens number has 2 digits.

A regular number has 1 digit (itself).

Three hundred means 300.

Three hundred thousand, would be 300 times 1,000 (one thousand), or adding 3 zeros.

Two hundred is 200.

One is 1.

300 times 1,000 is 300,000.

300,000 and 200 is 300,200.

If the ones digit has a 1, then the number is 300,201.

Three hundred thousand, two hundred one written in standard form is 300,201.
