Solve the inequality what is the solution?

Mathematics
1 answer:
bija089 [108]3 years ago
3 0

Answer:

The solution to the inequality is:

2\ge \frac{g}{-4}\quad :\quad \begin{bmatrix}\mathrm{Solution:}\:&\:g\ge \:-8\:\\ \:\mathrm{Interval\:Notation:}&\:[-8,\:\infty \:)\end{bmatrix}

Please also check the graph of the solution to the inequality.

Step-by-step explanation:

Given the inequality

2\ge \frac{g}{-4}

switch sides

\frac{g}{-4}\le \:2

Multiply both sides by -1 (reverse the inequality)

\frac{g\left(-1\right)}{-4}\ge \:2\left(-1\right)

Simplify

\frac{g}{4}\ge \:-2

Multiply both sides by 4

\frac{4g}{4}\ge \:4\left(-2\right)

Simplify

g\ge \:-8

Therefore, the solution to the inequality is:

2\ge \frac{g}{-4}\quad :\quad \begin{bmatrix}\mathrm{Solution:}\:&\:g\ge \:-8\:\\ \:\mathrm{Interval\:Notation:}&\:[-8,\:\infty \:)\end{bmatrix}

Please also check the graph of the solution to the inequality.

Health insurance benefits vary by the size of the company. The sample data below show the number of companies providing health i
telo118 [61]

Answer:

Step-by-step explanation:

a. The hypothesis of testing are

Null Hypothesis, H0: The health insurance coverage is independent of the size of the company.

Alternative hypothesis, H1: The health insurance coverage is not independent of the size of the company

The test statistics is calculated as

X² =  <u>∑(Ei - Oi)²</u>  ≅X²(r-1)(c-1)

        i      Ei

where Oi's are the observed values and Ei's are the expected values,

E= <u>row total × column total</u>

            total

The expected values are

        Sizeof the Company  

Health Insurance    Small   Medium Large Total

Yes                             42     63          84           189

No                              8             12          16           36

Total                      50    75                  100           225

Therefore, the test statistics is

X² =∑ (<u>Ei -Oi)² </u>=6.94 ≅  x²₂

      i       Ei

The critical value is found to be 5.99. Since test statistics > critical value, we reject H0 and conclude that the health insurance coverage is not independent of the size of the company.

The associated p-value is 0.031 (<0.05).

b. Percentage of employees lacking health insurance coverage is

Small 14/50 x 100 = 28%

Medium 10/75 x 100 = 13%

Large 12/100 x 100 = 12%

Hence depending on the above percentage, we can support the claim that the employees of small companies are more likely to lack health insurance coverage.

erastovalidia [21]
Option A would be your answer. We know 71 is the product. We also know that Sues age is one year less than half her mothers age. -1 comes from the problem saying one year less. We can already eliminate the other 3 options at this point.
