Answer:

Step-by-step explanation:

Let x be pineapple juice each serving

T be the final juice available

(1) T = 8x+5

(2) T+11 = 12x

Solving simultaneously,

(8x+5)+11 = 12x

8x+16 = 12x

4x = 16

x = 4

Pineapple Corporation (PC) maintains that their cans have always contained an average of 12 ounces of fruit. The production grou
krok68 [10]

Answer:

We accept the null hypothesis, that is, that the mean weight of the cans is still of 12 ounces of fruit.

Step-by-step explanation:

Pineapple Corporation (PC) maintains that their cans have always contained an average of 12 ounces of fruit.

This means that the null hypothesis is: H_0: \mu = 12

The production group believes that the mean weight has changed.

This means that the alternate hypothesis is:

H_a: \mu \neq 12

The test statistic is:

z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}

In which X is the sample mean, \mu is the value tested at the null hypothesis, \sigma is the standard deviation and n is the size of the sample.

12 is tested at the null hypothesis:

This means that \mu = 12

They take a sample of 15 cans and find a sample mean of 12.05 ounces and a sample standard deviation of .08 ounces.

This means, respectibely, that n = 15, X = 12.05, \sigma = 0.08

Value of the test statistic:

z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}

z = \frac{12.05 - 12}{\frac{0.08}{\sqrt{15}}}

z = 2.42

Pvalue of the test:

We are testing if the mean is different from a value, which means that the pvalue is 2 multiplied by 1 subtracted by the pvalue of z = 2.42.

Looking at the z-table, z = 2.42 has a pvalue of 0.9922

1 - 0.9922 = 0.0078

2*0.0078 = 0.0156

What conclusion can we make from the appropriate hypothesis test at the .01 level of significance?

0.0156 > 0.01. This means that at the 0.01 level, we accept the null hypothesis, that is, that the mean weight of the cans is still of 12 ounces of fruit.

Let f(x) = 3x - 5 and g(x) = x +10 Find f(g(x))
valkas [14]

Answer:

f(g(x)) = 3x + 25

General Formulas and Concepts:

<u>Pre-Algebra</u>

  • Distributive Property

<u>Algebra I</u>

  • Function Notation
  • Function Composition

Step-by-step explanation:

<u>Step 1: Define</u>

f(x) = 3x - 5

g(x) = x + 10

<u>Step 2: Find f(g(x))</u>

  1. Substitute:                    f(g(x)) = 3(x + 10) - 5
  2. Distribute 3:                  f(g(x)) = 3x + 30 - 5
  3. Subtract:                       f(g(x)) = 3x + 25
