Solve the inequality.
y – 5 ≥ 11
The solution to the inequality y - 5 ≥ 11 is y ≥ 16.
To solve the inequality y - 5 ≥ 11,
we need to isolate the variable y on one side of the inequality sign.
Adding 5 to both sides of the inequality, we have:
y - 5 + 5 ≥ 11 + 5
Simplifying, we get:
y ≥ 16
Therefore, the solution to the inequality y - 5 ≥ 11 is y ≥ 16.

The slope of a line is 0, and the y-intercept is 6. the equation, written as y = 6, represents a horizontal line. true false
The answer is: true.
Here's why:
A slope of 0 indicates a horizontal line, meaning there's no change in y-value as x changes.
A y-intercept of 6 means the line intersects the y-axis at the point (0, 6).
The equation y = 6 represents a constant y-value for any x, which indeed depicts a horizontal line that intersects the y-axis at (0, 6).
Therefore, both the slope and the equation confirm that the line is horizontal.

Which graph could represent the data shown below?
From the attached diagram you can see that regression that best fits given data is quadratic (not linear).
option 1 is false, because it gives linear regression;option 2 is true, it gives graph, similar to quadratic parabola;options 3 and 4 are false, because graphs are decreasing.Answer: correct choice is B.
The graph of the given values is required.
Option B is correct.
The points are
[tex](1,97)[tex]
[tex](2,168)[/tex]
[tex](3,259)[/tex]
[tex](4,375)[/tex]
Let us find if the points are in the form of a line by finding the slope.
[tex]\dfrac{168-97}{2-1}=71[/tex]
[tex]\dfrac{259-168}{3-2}=91[/tex]
[tex]71\neq 91[/tex]
So, the function is not linear.
Therefore, A and C are incorrect.
Also the function is not decreasing so option D is also eliminated.
Hence, option B is correct.

You know that a certain trait occurs in 30% of the population. You want to know how many individuals you have to draw from the population, on average, to get three subjects with the trait.
To find out how many individuals you have to draw from the population, on average, to get three subjects with the trait, you can use the geometric distribution. The average number of trials until the third success can be calculated by dividing 1 by the probability of success.
Explanation:To find out how many individuals you have to draw from the population, on average, to get three subjects with the trait, you can use the geometric distribution.
The probability of success (finding an individual with the trait) is 30% or 0.30, and the probability of failure is 70% or 0.70.
To calculate the average number of trials until the third success, you divide 1 by the probability of success:
1 / 0.30 = 3.33
Therefore, on average, you would have to draw from the population about 3.33 individuals to get three subjects with the trait.

susan wants to buy a paddle boat for $840. She will pay 20% down and pay the rest in six months installments. what will be the amount of each monthly payments?
Susan's down payment for the paddle boat is $168, with the remaining $672 divided into six monthly payments of $112 each.
Susan wants to buy a paddle boat for $840. She will pay 20% down and the rest in six monthly installments. To calculate the down payment, we calculate 20% of $840, which is $168.
The remaining amount after the down payment is $840 - $168 = $672. This remainder will be paid in six monthly installments, so we divide $672 by 6 to get the monthly payment amount.
The amount of each monthly payment will therefore be $672 / 6 = $112 per month.
Therefore, as per the above explaination, the correct answer is $112.
miguel is making smoothies out of yogurt and juice to serve his friends, and he needs to make 12 cups. the ratio of yogurt to juice is 2 cups to 1 cup. how much yogurt will he use
Answer:
Eight cups of yogurt will be used.
Step-by-step explanation:
Let cups of yogurt used in 12 cups of smoothies be x
Cups of juice used in 12 cups of smoothies = 12- x
The ratio of yogurt to juice is 2 cups to 1 cup that is:
[tex]\frac{Yogurt}{Juice}=\frac{2}{1}[/tex]
Ratio will be maintained through out 12 cups of smoothies:
[tex]\frac{Yogurt}{Juice}=\frac{2}{1}=\frac{x}{12-x}[/tex]
[tex]2(12-x)=1(x)[/tex]
[tex]24-2x=x[/tex]

x = 8

At which angle will the hexagon rotate onto itself?
Answer:
The correct answer is: 60°
Step-by-step explanation:
Rotational symmetry is a type of symmetry, in which an object returns back to its original shape after rotation at an angle of 360°/n about a fixed point.
A hexagon is a regular polygon that has six edges and vertices. It has six internal angles, 120° each.
Since there are 6 equal edges, therefore, the hexagon will rotate onto itself after every rotation at an angle of: 360°/n = 360°/6 = 60°
