Answer:

Average low temp. = 6.  The fourth number is 9.

Step-by-step explanation:

To find the average of 7 low temperatures, add them and divide the sum by 7.

Average low temp. = (5 + 8 + 6 + 5 + 10 + 7 + 1) / 7 = 42 / 7 = 6

The mean is the average.  Call the missing number  x.

There are four numbers, three of which are given.  Add all the number, including the unknown  x, then divide the sum by 4.  The result is 7 (given in the problem).

\frac{5+7+7+x}{4}=7\\\frac{19+x}{4}=7\\19+x=28\\x=9

victus00 [196]

Answer: 9.98 meters

Step-by-step explanation:

Angle = 12°

Displacement = 48 m

The height, or displacement in the y-axis will be equal to the opposite cathetus of a triangle rectangle where the hypotenuse is the displacement, then we can find that the displacement in the y-axis is:

h = sin(12°)*48m = 9.98m

The Coca-Cola Company reported that the mean per capita annual sales of its beverages in the United States was 423 eight-ounce s
Gekata [30.6K]

Answer:

The test results support the claim

Step-by-step explanation:

The Coca-Cola Company reported that the mean per capita annual sales of its beverages in the United States was 423 eight ounce servings (Coca-Cola Company website, February 3, 2009).

Suppose you are curious whether the consumption of Coca-Cola beverages is higher in Atlanta, Georgia, the location of Coca-Cola’s corporate headquarters.

A sample of 36 individuals from the Atlanta area showed a sample mean annual consumption of 460.4 eight ounce servings with a standard deviation of s = 101.9 ounces. Using α = .05, do the sample results support the conclusion that mean annual consumption of Coca-Cola beverage products is higher in Atlanta?

Hx: u <= 423 oz

Ha: u > 423 oz (claim)

z(460.4) = (460.4-423)/[101.9/sqrt(36)] = 2.2022

p-value = P(z > 2.2022) = 0.0138

Conclusion: Since the p-value is less than 5%

reject Hx at the 5% significance level.

The test results support the claim.
