In mathematics, an arithmetic progression (AP) or arithmetic sequence is a sequence of numbers such that the difference between the consecutive terms is constant. For instance, the sequence 5, 7, 9, 11, 13, 15, . . . is an arithmetic progression with common difference of 2.

Answer:

13 and 27

Step-by-step explanation:

y= x+14

x+y=40

x+ x+14=40

2x+14=40

40-14=26

so, 2x=26

26/2

=13

so, x=13 and

and y equal 40-13

y=27

Answer:

$P(x \le 3.24) = 0.97725$

Step-by-step explanation:

Given

$\bar x = 2.5$

$\sigma = 0.37$

Required

Percentage that is not more than 3.24

The above implies that:

$x = 3.24$

Calculate z score

$z = \frac{x - \bar x}{\sigma}$

$z = \frac{3.24 - 2.5}{0.37}$

$z = \frac{0.74}{0.37}$

$z = 2$

So, the probability is represented s:

$P(x \le 3.24) = P(z \le 2)$

From z probability

$P(z \le 2) = 0.97725$

Hence:

$P(x \le 3.24) = 0.97725$
