What is the equation of a horizontal line that passes
through the point (-4, -5)?

Answers

Answer 1
Answer:

Answer: y=-5

Step-by-step explanation:

A horizontal line appears on the graph if it goes through the y-axis. Knowing this, the coordinate tells us that the y-coordinate is -5. This tells us that the equation of the line is y=-5.

A sample of 56 randomly selected cellphones of a new model were checked for a particular defect. Of these, 38 of the cellphones were found to be defective. Find a 80% confidence interval for p. Use the Agresti-Coull method.

Answers

Answer:

Confidence Interval: (0.60, 0.76)

Step-by-step explanation:

The provided information is:

Sample Size (n) = 56

Consider X be the number of defective cellphones. Then X = 38

Proportion of defective cellphones is: p=(38)/(56)=0.68

At 80% confidence interval, value of z is 1.28

Thus, the 80% confidence interval for proportion is given as:

p\pm z\sqrt{(p(1-p))/(n)}}\n=0.68\pm1.28\sqrt{(0.68*0.32)/(56)}\n=(0.60,0.76)

What are the solution(s) to the quadratic equation 9x2 = 4?x =4/9 and x = -4/9
x = 2/3 and x = -2/3
x = 3/2 and x = -3/2
no real solution

Answers

we have

9x^(2)=4

Divide both sides by 9

9x^(2)/9=4/9

x^(2)=4/9

Square root both sides

x=(+/-)\sqrt{(4)/(9)}

x=(+/-)(2)/(3)

so

the solutions are

x1=(2)/(3)

x2=-(2)/(3)

therefore

the answer is the option

x = 2/3 and x = -2/3

The solutions to the quadratic equation; 9x2 = 4 are; x = 2/3 and x = -2/3.

Quadratic solutions

The given quadratic equation is;

  • 9x² = 4.

Hence, upon evaluation; we have;

  • x² = 4/9

Hence, x = ±2/3

Therefore, x = 2/3 and x = -2/3
