Answer:

  -19/7

Step-by-step explanation:

If the variation is direct, any multiplier of the m-value will also multiply the f-value.

 old value × 1/7 = new value

 m: 14 × 1/7 = 2

 f: -19 × 1/7 = -19/7

The new value of f is -19/7.

Aleonysh [2.5K]

For the given conditions, we won’t get a practical solution.

<u>Solution:</u>

Given, An automobile dealer had 288 cars and trucks in stock during the month.  

He must pay an inventory fee of 52 per car and $5 per truck.  

He paid $849 for inventory foes.  

We have to find how many cars and Trucks did he have during the month?

Now, let the number of trucks be n, then number of cars will be 288 – n

And, according to given information,

\begin{array}{l}{5 \times n+52 \times(288-n)=849} \\\\ {\rightarrow 5 n+52 \times 288-52 n=849} \\\\ {\rightarrow 52 n-5 n=14976-849} \\\\ {\rightarrow 47 n=14127} \\\\ {\rightarrow n=300.57}\end{array}

Here we got n > number of cars and trucks, which is practically impossible.  

Hence, for the given conditions, we won’t get a practical solution

According to the 68-95-99.7% rule, what percentage of the data from a bell-shaped distribution will be within one standard devia
mote1985 [20]

Answer:

68% of the distribution will be within one standard deviation of the mean

Step-by-step explanation:

The Empirical Rule states that, for a normally distributed random variable:

68% of the measures are within 1 standard deviation of the mean.

95% of the measures are within 2 standard deviation of the mean.

99.7% of the measures are within 3 standard deviations of the mean.

Bell-shaped = Normally distributed.

This means that 68% of the distribution will be within one standard deviation of the mean
