Answer:

The volume of the cylinder is 6,104.16 square meters.

Step-by-step explanation:

Given that a cylinder has a height of 6 meters and a diameter that is 6 times the measure of the height, to determine, using 3.14 for pi, which of the following can be used to calculate the volume of the cylinder, the following calculation must be done, knowing that the volume of a cylinder is determined by multiplying Pi by the height by the radius squared, and that the diameter of a circle is twice its radius:

3.14 x 6 x (6x3) ^ 2 = X

18.84 x 18 ^ 2 = X

18.84 x 324 = X

6,104.16 = X

Therefore, the volume of the cylinder is 6,104.16 square meters.

Suppose you have purchased a filling machine for candy bags that is supposed to fill each bag with 16 oz of candy. Assume that t

nexus9112 [7]

Answer:

H0: μ ≥ 16

H1: < 16

−2.748749;

0.011275;

Reject the Null

Step-by-step explanation:

Given the data:

15.87, 16.02, 15.78, 15.83, 15.69, 15.81, 16.04, 15.81, 15.92, 16.10

Null hypothesis ; H0: μ ≥ 16

Alternative hypothesis ; H1: < 16

Sample size, n = 10

From the data:

Using calculator,

Sample mean, m = 15.887

Standard deviation, s = 0.13

The test statistic, T

(m - μ) / s/sqrt(n)

(15.887 - 16) / (0.13/sqrt(10))

= −2.748749

Using the p value from test statistic calculator :

Degree of freedom (df) = 10 - 1 = 9 at 0.05 significance level is 0.011275

Since the p value is < 0.05

0.011 < 0.05

We reject the Null and conclude that the mean fill weight is less than 16 oz

A house worth $70,000 when purchased was worth $67,000 after the first year and $64,000 after the second year. If the economy do

Citrus2011 [14]

Answer:

a) The formula for the sequence is

$a_n = 67,000 -3,000(n-1)$

b) $a_7 = 49,000$

Step-by-step explanation:

Note that the difference between any two consecutive terms in the sequence is always equal to $3,000

$67,000-70,000= -3,000\\\\64,000-67,000=-3,000$

Then we have an arithmetic sequence where each term increases by a magnitude of 3,000 with respect to the previous term.

The explicit formula for an arithmetic sequence is:

$a_n = a_1 +d(n-1)$

Where d is the common difference between the consecutive terms of the sequence

$d = -3,000$

$a_1$ is the first term, or the value of the house after year 1 $a_1= 67,000$

n represents the number of years since the house was purchased

With

n={0, 1, 2, 3, 4, 5, 6, 7,.., n}

a) Then the formula for the sequence is

$a_n = 67,000 -3,000(n-1)$

With

n={0, 1, 2, 3, 4, 5, 6, 7,.., n}

---------------------------------------------------------------------------------------------

b) Now we can use the formula to find the price of the house after 7 years

$a_7 = 67,000 -3,000(7-1)$

$a_7 = 67,000 -3,000(6)$

$a_7 = 49,000$
