Answer:

x≤7.8  ⇒(-∞;7.8]

x<7.8  ⇒ (-∞;7.8)

x>7.8  ⇒ (7.8; ∞)

x≥7.8  ⇒ [7.8; ∞)

Step-by-step explanation:

Hi, to answer this question we have to analyze each expression:

• x≤7.8

The solution is all the numbers less or equal to 7.8, since it can be equal to 7.8, it includes 7.8 , we have to use closed brackets

(-∞;7.8]

• x<7.8

All the numbers less than 7.8 , it excludes the endpoint , it's an open interval (parenthesis)

(-∞;7.8)

• x>7.8

All the numbers higher than 7.8, open interval (parenthesis)

(7.8; ∞)

• x≥7.8

All the numbers higher or equal to 7.8, closed interval (closed brackets for the endpoint)

[7.8; ∞)

The mean annual incomes of certified welders are normally distributed with the mean of $50,000 and a standard deviation of $2,00
SCORPION-xisa [38]

Answer:

Therefore, for the case above; the Alternative hypothesis is;

H1: is not equal to $50,000.

H1: ≠ $50,000.

Step-by-step explanation:

The null hypothesis (H0) tries to show that no significant variation exists between variables or that a single variable is not different than its mean.

While an alternative Hypothesis (Ha) attempt to prove that a new theory is true rather than the old one. That a variable is significantly different from the mean.

Therefore, for the case above; the Alternative hypothesis is;

H1: is not equal to $50,000.

H1: ≠ $50,000.

What are the y-intercept and the horizontal asymptote of g(x) = 3x + 4?
Stells [14]

The coefficient of the variable will be the horizontal  asymptote . Hence the horizontal  asymptote will be 3

<h3>How to calculate the y-intercept and horizontal asympototes</h3>

Given the function g(x) = 3x + 4

The y-intercept is the point where x = 0

g(0) = 3(0) + 4
g(0) = 0 + 4
g(0) = 4

Hence the y-intercept is at (0, 4)

For the horizontal  asymptote of g(x) = 3x + 4

The coefficiet of the variable will be the horizontal  asymptote . Hence the horizontal  asymptote will be 3
