A recent study of food portion sizes reported that over a 17-year period, the average size of a soft drink consumed by Americans

aged 2 years and older increased from 13.1 ounces (oz) to 19.9 oz. The authors state that the difference is statistically significant with P < 0.01.† Explain what additional information you would need to compute a confidence interval for the increase, and outline the procedure that you would use for the computations.

We are given with
initial consumption = 13.1
consumption after 17 years = 19.9

What can be concluded from the pie chart?
QveST [7]

The information that can be concluded from the pie chart is in 2018, more than one-fourth of the revenue collected for state and local governments in Florida came from sales taxes.

A pie chart is a circular graph that is used to show information. The circle is divided into sectors used to represent a numerical proportion. A pie chart adds up to 100%.

The pie chart in this question shows the sources of state and local revenue for Florida in 2018. The circle is divided into seven sectors that represent the sources of revenues.

The following can be deduced from the pie chart:

  • Excise taxes represent 1.2% of 100% of the circle. This is the smallest source of revenue for the state of Florida. Corporate income taxes represent 2% of the circle. Income from excise tax was less than income from corporate income taxes.

  • The sector that represents property tax is 13.7% and the sector that represents sales tax is 26.1%. Sales tax was a greater source of revenue when compared with property tax.

  • The proportion of sales tax to total revenue is 26.1%. This is more than 25%(1/4) of total revenue.

Jodi poured herself a cold soda that had an initial temperature of 40degreesF and immediately went outside to sunbathe where the
kozerog [31]

Answer:

58.75 degreeF

Step-by-step explanation:

The initial temperature of the Soda = 40degreeF

The temperature outside is steady at 99 degreeF

The temperature of the soda became 50 degreeF after 8 minutes

In 8 minutes, the Soda gained

(50 - 40)degreeF

= 10 degreeF

If the soda gains 10 degreeF in 8 minutes, in 1 minute, it will gain 10/8degreeF

Therefore in 7 minutes, the soda will gain (10/8)*7

= 70/8

= 8.75 degreeF

The expected temperature of soda after an additional 7 minutes = 50 + 8.75

= 58.75degreeF

Two angles of a triangle have the same measure and the third one is 18 degrees greater than the measure of each of the other two
kvv77 [185]

Answer:

72°

Step-by-step explanation:

Let the 2 equal angles be x then the third angle is x + 18

The sum of the 3 angles in a triangle = 180°, thus

x + x + x + 18 = 180, that is

3x + 18 = 180 ( subtract 18 from both sides )

3x = 162 ( divide both sides by 3 )

x = 54

Hence

the largest angle = x + 18 = 54 + 18 = 72°
