Answer: After five minutes the plane is at 10,000. feet.

Step-by-step explanation:

f = feet above ground

r = rate of descent

m = minutes

f = 30000 - r · m

f = 30000 - 20000m

After five minutes:

f = 30000 - 2000(5)

f = 30000 - 10000

f = 20000

What is the largest of three consecutive positive integers if the product of the two smallest is equal to 2 more than 8 times th

pogonyaev

Answer:

Step-by-step explanation:

n, n + 1, n + 2 - three consecutive integers

The equation:

n(n + 1) = 8(n + 2) + 2 ust the distributive property

n² + n = 8n + 16 + 2

n² + n = 8n + 18 subtract 8n from both sides

n² - 7n = 18 subtract 18 from both sides

n² - 7n - 18 = 0

n² - 9n + 2n - 18 = 0

n(n - 9) + 2(n - 9) = 0

(n - 9)(n + 2) = 0 ⇔ n - 9 = 0 or n + 2 =0

n - 9 = 0 add 9 to both sides

n = 9

n + 2 = 0 subtract 2 from both sides

n = -2 < 0

n + 2 = 9 + 2 = 11

Calvin thinks a certain potato chip maker is putting less product in their personal-sized bags of chips. In the past, these bags

Strike441 [17]

Answer:

a) There are no evidence that Calvin is correct.

b) There are evidence that Calvin is correct.

Step-by-step explanation:

We are given the following in the question:

Population mean, μ = 1 ounce

Sample size, n = 23

First, we design the null and the alternate hypothesis

$H_{0}: \mu = 1\text{ ounce}\\H_A: \mu < 1\text{ ounce}$

P-value = 0.086

a) Significance level = 5% = 0.05

Since

P-value > Significance level

We fail to reject the null hypothesis and accept it. Thus, the chips bag contain one ounce of product. Thus, there are no evidence that Calvin is correct.

b) Significance level = 10% = 0.10

Since

P-value < Significance level

We reject the null hypothesis and accept the alternate hypothesis. Thus, the chips bag contain less than one ounce of product. Thus, there are evidence that Calvin is correct.
