You are competing in a race. The table shows the times from last year's race. You want your time to be last year's median time w

olasank [31]

Answer:

28 ≤ x ≤40

Step-by-step explanation:

Arrange the data from the smallest to the largest

26, 27, 28,32, 32, 33, 35, 36, 38, 40,42,48

Identify the median value

26, 27, 28,32, 32,<u> 33, 35</u>, 36, 38, 40,42,48

Getting the median

(33+35)/2 = 68/2 = 34 minutes

You want your time to be last year's median time with an absolute deviation of at most 6 minutes

This mean ±6 minutes, hence this will be 34 ± 6

34+6=40 and 34-6=28

The inequality will be 28 ≤ x ≤40

Paulita reads an average of 20 pages each day. She has 6 days to read 10^2 pages. Will she finish her reading in 6 days? Explain

MissTica

Yes, she would finish in time because 10^2=100, if she reads 20 pages per day, it'll take her 5 days to finish her reading before the 6 days

Pre-image point N(6, -3) was dilated to point N'(2, -1). What was the scale factor used?

blagie [28]

Question 1

Let the scale factor be k.

Then, we have the mapping

$N(6,-3)\to N'(6k,-3k)$

This implies that:

$(6k,-3k)=(2,-1)$

We equate any corresponding component find the value of the scale factor k.

6k=2

$k=\frac{2}{6}$

$k=\frac{1}{3}$

Hence the scale factor is $\frac{1}{3}$

Question 2:

The midpoint of any two points can be calculated using the formula;

$(\frac{x_1+x_2}{2}, \frac{y_1+y_2}{2})$

We want to find the midpoint of (-8, 5) and (2, -2).

$(\frac{-8+2}{2}, \frac{5+-2}{2})$

$(\frac{-6}{2}, \frac{3}{2})$

The midpoint is:

$(-3, \frac{3}{2})$
