Answer:

Step-by-step explanation:

Length of rectangle = 3x + 4

Width of the rectangle = 2x + 6

Perimeter of rectangle = 2(l + b)

45 = 2(3x + 4 + 2x + 6)

45 = 2(5x + 10)

45 = 10x + 20

45 - 20 = 5x

25 = 5x

x = 25/5

x = 5

A male student of the author has a measured pulse rate of 52 beats per

Liono4ka [1.6K]

Answer:

$z=-1.49$

Step-by-step explanation:

$\text{Standard Score, z} =\dfrac{X-\mu}{\sigma} $ where:\\\\Mean Pulse rate, \mu =67.3$ beats per minute\\Standard Deviation, \sigma = 10.3$ beats per minute.\\$

For a male student who has a measured pulse rate of 52 beats per minute.

Raw Score, X =52 beats per minute.

Therefore:

$\text{Standard Score, z} =\dfrac{52-67.3}{10.3}\\z=-1.49$

Since the usual pulse rates are within 2 standard deviations of the mean, a z-score of -1.49 tells us that the selected student's pulse rate is within the usual pulse rates.
