Food = 1/4
gasoline = 3/5
Total = 1/4 + 3/5 = 17/20

17/20 = 272
1/20 = 272 ÷ 17 = 16
20/20 = 16 x 20 = $320

Kobotan [32]

Answer: 5% approximately

Step-by-step explanation:

Jen earns $35,650 a year working for an electronics supplier and pays $1,749.80 in state income tax each year. To calculate the income tax rate, we divide the amount paid as tax by her annual income and then multiply by 100. This will be:

= 1749.80/35650 × 100

= 4.91%

= 5% approximately

The state's tax rate is 5%.

When plotting sample statistics on a control chart, 99.7% of the sample statistic values are expected to fall within plus/minus

Blababa [14]

Answer:

By the Empirical Rule, $\pm 3\sigma$

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.

The symbol of a standard deviation is $\sigma$ . So

When plotting sample statistics on a control chart, 99.7% of the sample statistic values are expected to fall within plus/minus how many sigma?

By the Empirical Rule, $\pm 3\sigma$
