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

What percent of 48 is 12?

g100num [7]

Answer:

25%

Step-by-step explanation:

Given that we have to find what percent of 48 is 12

Let "x" be the required percent

From given statement,

what percent of 48 is 12

Let us say,

x percent of 48 is 12

Writing it mathematically we get,

x % of 48 is 12

Evaluate the above expression to find "x"

Thus 25 % of 48 is 12

The perimeter of the rectangle below is 134 units. Find the length of side RS. Write your answer without variables

Eddi Din [679]

Answer:

RS = 30 units

Step-by-step explanation:

Given:

Length (PS) = $4y + 1$

Width (PQ) = $3y + 3$

Perimeter = 134 units

Required:

RS (width)

SOLUTION:

Perimeter of a rectangle = 2(length + width)

Plug in the values into the equation

134 = 2[(4y + 1) + (3y + 3)]

134 = 2[4y + 1 + 3y + 3]

134 = 2[7y + 4]

134 = 14y + 8

Subtract 8 from each side of the equation

134 - 8 = 14y

126 = 14y

Divide both sides by 14.

126/14 = 14y/14

9 = y

y = 9

✍️RS = Width (PQ) = $3y + 3$

Plug in the value of y

RS = tex] 3(9) + 3 [/tex]

RS = tex] 27 + 3 [/tex]

RS = 30
