The number of calories burned at the gym is normally distributed with a mean of 425 and a standard deviation of 51. Find the Z-s

Galina-37 [17]

Answer:

(a) -3.708

(b) 1.706

(c) 0.490

Step-by-step explanation:

The z-score of normal distribution is given as:

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

(a)

Given:

Score is, $x=268$

Mean value is, $\mu =425$

Standard deviation is, $\sigma = 51$

z-score is, $z=\frac{268-425}{51}=\frac{-157}{51}=-3.078$

(b)

Given:

Score is, $x=512$

Mean value is, $\mu =425$

Standard deviation is, $\sigma = 51$

z-score is, $z=\frac{512-425}{51}=\frac{87}{51}=1.706$

(c)

Given:

Score is, $x=450$

Mean value is, $\mu =425$

Standard deviation is, $\sigma = 51$

z-score is, $z=\frac{450-425}{51}=\frac{25}{51}=0.490$

Express the recurring decimal 0.034 as a fraction in its simplest form.

LiRa [457]

Answer:

$\frac{17}{495}$ will be the fraction.

Step-by-step explanation:

Here the recurring decimal number is 0.0343434....

To convert this recurring decimal to fraction we assume,

x = 0.03434.... -------(1)

Now multiply both the sides with 100.

100x = 3.43434.... ------(2)

Now subtract equation (1) from equation (2).

100x = 3.43434

99x = 3.4

x = $\frac{3.4}{99}$

= $\frac{34}{990}$

x = $\frac{17}{495}$

Therefore, fraction that represents the decimal number is $\frac{17}{495}$
