What is the mean of the following data values?<br> 22, 37, 49, 15, 92
attashe74 [19]

Answer:

43

Step-by-step explanation:

First, you have to add 22+37+49+15+92 to get 215. To find the mean, you need to divide by how much numbers there are (5).  So 215 divided by 5 is 43!

Compute the lower Riemann sum for the given function f(x)=x2 over the interval x∈[−1,1] with respect to the partition P=[−1,− 1
Nata [24]

Answer:

21/64

Step-by-step explanation:

First, we need to note that the function f(x) = x² is increasing on (0, +∞), and it is decreasing on (-∞,0)

The first interval generated by the partition is [-1, -1/2], since f is decreasing for negative values, we have that f takes its minimum values at the right extreme of the interval, hence -1/2.

The second interval is [-1/2, 1/2]. Here f takes its minimum value at 0, because f(0) = 0, and f is positive otherwise.

Since f is increasing for positive values of x, then, on the remaining 2 intervals, f takes its minimum value at their respective left extremes, in other words, 1/2 and 3/4 respectively.

We obtain the lower Riemman sum by multiplying this values evaluated in f by the lenght of their respective intervals and summing the results, thus

LP(f) = f(-1/2) * ((-1/2) - (-1)) + f(0) * (1/2 - (-1/2)) + f(1/2)* (3/4 - 1/2) + f(3/4) * (1- 3/4)

= 1/4 * 1/2 + 0 * 1 + 1/4 * 1/4 + 9/16 * 1/4 = 1/8 + 0 + 1/16 + 9/64 = 21/64

As a result, the lower Riemann sum on the partition P is 21/64

The city library donated some children’s books to Mr.

According to the statement 160 books were given to the class.

The correct option is C.

<h3>What is linear equation?</h3>

One or two variables make up a linear equation. Neither the numerator nor the denominator of a fraction can be a variable in a linear equation raised to a power higher than 1. All of the points on a coordinate grid sit on the same line when you identify the values that together make a linear equation true and plot those values.

<h3>According to the given information:</h3>

Let the no. of students be s:

Let the no. of books be b:

Given that there will be 20 books left after each student selects 4 books,

b = 4s + 20

And the remaining students take 5 books each, therefore b=5(s3), even if 3 pupils choose not to take a book.

comparing the value b

4s+20=5(s−3)

4s+20=5s−15

s=20+15

s=35

To do this, change the value of s in b=4s+20 to what is shown below:

b=4(35)+20

b=140+20

b=160

160 books were given to the class.
