10% of $560 is $56

So 5% is $28

1% of $560 is $5.60

So now half $5.60 is $2.80

$2.80 is 0.05%

Now add

$28 + $2.80 = $30.80

Total is $30.80

JulsSmile [24]

Answer:

SD = 7588.09

Step-by-step explanation:

Check the distribution table attached to for the step by step solution:

The formula for the mean, \bar{x} = \frac{\sum fx}{\sum f}

\bar {x} = \frac{1410040}{80} \\\bar {x} = 17625.5

The variance , V(X) = \sqrt{\frac{\sum f(x - \bar{x}^2)}{n-1} }

V(X) = \frac{4548750000}{80 - 1} \\V(X) = 57579113.92

Standard Deviation,

SD = \sqrt{V(X)} \\SD = \sqrt{57579113.92}

SD = 7588.09

Ray Of Light [21]

Answer: 0.0062

Step-by-step explanation:

Given : The weight of trucks traveling on a particular section of I-475 have a population mean of \mu=15.8 tons and a population standard deviation of \sigma=4.2 tons.

Sample size : n=49

Let x be the random variable that represents the weight of trucks .

z-score : z=\dfrac{x-\mu}{\dfrac{\sigma}{\sqrt{n}}}

For x= 14.3 tons

z=\dfrac{14.3-15.8}{\dfrac{4.2}{\sqrt{49}}}\approx-2.5

Now, the probability a state highway inspector could select a sample of 49 trucks and find the sample mean to be 14.3 tons or less will be :-

P(X\leq14.3)=P(z

Hence, the probability a state highway inspector could select a sample of 49 trucks and find the sample mean to be 14.3 tons or less =0.0062
