Answer:

D. 46.5 in.–73.5 in.

Step-by-step explanation:

We have been given that horn lengths of Texas longhorn cattle are normally distributed.

\text{The mean spread for horn lengths of Texas cattle } (\mu)=\text{60 inches}

\text{The standard deviation for horn lengths of Texas cattle } (\sigma)=\text{4.5 inches}

Since the empirical rule states that about 99.7% of the population lies within the 3 standard deviation. So according to normal distribution the range for the middle 99.7% of the values is: [\mu-3\sigma,\mu+3\sigma].

Upon substituting our given values we will get,

[60\text{ inches }-3*4.5\text{ inches },60\text{ inches }+3*4.5\text{ inches }]

[60\text{ inches }-13.5\text{ inches },60\text{ inches }+13.5\text{ inches }]

[46.5\text{ inches },73.5\text{ inches }]

Therefore, the range of horn lengths for the middle 99.7% of Texas longhorn cattle is 46.5 inches to 73.5 inches and option D is the correct choice.

The price of milk increased from $3.25 to $3.75. What is the percent of change for the price of milk to the nearest tenth? Show
nikitadnepr [17]
Percent = part/whole

It wants you to find the % of change so it's 3.25 / 3.75
And that comes out to be 0.86 (with the 6 repeating)
So you move the decimal over 2 places to find the percent.
And then it's 1 - Ans

The answer is 13.33%
