Answer: $18

Step-by-step explanation:

You had a total of $60.

You spent 30% of your money on shorts.

The question would like to know what that 30% translates to in actual dollars so you need to find out what 30% of $60 is:

= 30% * 60

= $18

Weekly wages at a certain factory are

Furkat [3]

Answer: 0.1359

Step-by-step explanation:

mean = $400

Standard deviation = $50

Since the wages is normally distributed , the first thing is to find the z - score.

z = $\frac{x-mean}{standard deviation}$

finding the z - value for 300 and 350 , we have

z = $\frac{300-400}{50}$

z = $\frac{-100}{50}$

2 = -2

also

z = $\frac{350-400}{50}$

z = $\frac{-50}{50}$

z = -1

The next thing is to check the calculated value on z - table.

From z - table :

P (z $\leq$ -2 ) = 0.0228

P ( z $\leq -1$ ) = 0.1587

combining the two

P ( -2 $\leq$ z $\leq$ -1 ) = 0.1587 - 0.0228

P ( -2 $\leq$ z $\leq$ -1 ) = 0.1359

Therefore , the the probability that a worker

selected at random makes between

$300 and $350 = 0.1359

Correct answer is A.

$\tan{12^o}= \frac{45}{x} 
\\
\\x= \frac{45}{\tan{12^o}}} 
\\
\\x \approx 212 \text{ m}$
