For each value of X, determine wether it is a solution to
The solutions of -1 + 3x ≥ 14 are 5 and 8.
Linear Inequality:A linear inequality is a Mathematical expression that represents that both sides are not equal. In simple words, we can say that If the relationship makes a non-equal comparison between any two numbers or expressions, then it is known as Linear inequality.
Here we have
-1 + 3x ≥ 14
To determine the solutions of a given linear inequality substitute each value of x and check if the value satisfies the given expression
At x = 5 ⇒ -1 + 3(5) ≥ 14
⇒ -1 + 15 ≥ 14
⇒ 14 ≥ 14
∴ x = 5 is a solution to -1 + 3x ≥ 14
At x = 8 ⇒ -1 + 3(8) ≥ 14
⇒ -1 + 24 ≥ 14
⇒ 23 ≥ 14
∴ x = 8 is a solution to -1 + 3x ≥ 14
At x = -4 ⇒ -1 + 3(-4) ≥ 14
⇒ -1 - 12 ≥ 14
⇒ - 13 ≥ 14 [ which is not true ]
∴ x = - 4 is not a solution to -1 + 3x ≥ 14
At x = 2 ⇒ -1 + 3(2) ≥ 14
⇒ -1 + 6 ≥ 14
⇒ 5 ≥ 14 [ which is not true ]
∴ x = 2 is a solution to -1 + 3x ≥ 14
Therefore,
The solutions of -1 + 3x ≥ 14 are 5 and 8

LCM stands for 'Least Common Multiple'. The least common multiple (LCM) of two numbers is the lowest possible number that can be divisible by both numbers. It can be calculated for two or more numbers as well. There are different methods to find the LCM of a given set of numbers. One of the quickest ways to find the LCM of two numbers is to use the prime factorization of each number and then the product of the highest powers of the common prime factors will be the LCM of those numbers.

Write an equation in slope-intercept form for the line that passes through (9, 12) and is perpendicular to y=4
Answer:
[tex]x=9[/tex]
Step-by-step explanation:
First, let's determine the slope! We know that the line is perpendicular to [tex]y=4[/tex]. This line is just a horizontal line that crosses the y-axis with a slope of 0. The line perpendicular to this will have the form [tex]x=?[/tex]. This is a straight, vertical line with indeterminate slope.
The line passes through the point (9, 12). If the line is going straight up and down, it will intercept every y-value, but only one x-value. The x-value in this ordered pair is 9. Therefore, the equation of the line is [tex]x=9[/tex].

Your class is selling boxes of flower seeds as a fundraiser. The total profit p depends on the amount x that your class charges for each box of seeds. The equation p = -0.5x^2 + 36x -113 models the profit of the fundraiser. What's the smallest amount, in dollars, that you can charge and make a profit of at least $409?
The smallest amount that can be charged per box of seeds to make a profit of $409 is $20.125
What is a profit?A profit is the financial gain from a business transaction when the revenue from the transaction exceeds the expenses and taxes.
The function for the profit from the fund raiser is; p = -0.5·x² + 36·x - 113
When the profit is $409, we have;
p = 409 = -0.5·x² + 36·x - 113
-0.5·x² + 36·x - 113 = 409
-0.5·x² + 36·x - 522 = 0
The solutions of the above quadratic function, found using the quadratic formula are as follows;
x = (-36 ± √(36² - 4×(-0.5)×(-522)))/(2×(-0.5))
From which we have;
x = (-36 + √(36² - 4×(-0.5)×(-522)))/(2×(-0.5)) ≈ 20.125
x = (-36 - √(36² - 4×(-0.5)×(-522)))/(2×(-0.5)) ≈ 51.875
Therefore, when the profit is $409, the amount charged are x ≈ 51.875 or x ≈ 20.125
The smallest amount charged when the profit is $409 is therefore;
x ≈ $20.125

part a and b.
The coordinates on the x-axis (the x-intercepts) and y-axis (the y-intercepts) are;
(a) (i) The point, A = (6, 0)
(ii) The point B = (0, 6)
(b) The point A = (4, 0)
The point B = (0, 3)
What are the x and y-intercepts of a graph?The x and y-intercepts are the points at which the graph intersects the x-axis and the y-axis respectively. The coordinates of the points are (x, 0) and (0, y) respectively.
(a) (i) The equation of the line of the graph is; x + y = 6
The x-intercept of the line is at point A
The y-intercept of the line is at point B
At the x-intercept, the y-coordinate is 0, from the equation, x + y = 6, when y = 0, we get;
x + y = 6
x + 0 = 6
x = 6
The coordinate of the x-intercept, A = (6, 0)
(ii) The y-coordinate of the y-intercept is the value c of the equation of the line y = m·x + c
The x-coordinate at the y-intercept is 0
Rearranging the equation, x + y = 6, we get;
y = -x + 6
The y-coordinate at the y-intercept is therefore, c = 6
The point B is therefore; (0, 6)
(b) (i) The equation of the line is 4·y + 3·x = 12
The equation can be rearranged so that we get;
4·y + 3·x = 12
4·y = 12 - 3·x
y = (12 - 3·x) ÷ 4 = 3 - (3/4)·x
y = 3 - (3/4)·x
At the x-intercept, the value of y is 0. Plugging in y = 0 in the equation, y = 3 - (3/4)·x, we get;
0 = 3 - (3/4)·x
3 = (3/4)·x
x = 3 ÷ (3/4) = 4
x = 4,
y = 0 and x = 4, therefore the coordinate of the point A is (4, 0)
(ii) The y-intercept is point B
The x-value at the y-intercept is 0
Plugging the value x = 0 in the equation y = 3 - (3/4)·x, we get;
y = 3 - (3/4)× 0 = 3
x = 0 and y = 3
The coordinate of the point B is (0, 3)

The correct option is option (d).
Using Combination,
Total 120, different samples of size 3 (without replacement) can be taken from a finite population of size 10.
Population size: The population is the entire group of guesses. A sample is a specific group for which you collect data. It is denoted by N.
Sample Size: The sample size is always smaller than the total size of the population. A sample is a subset of the population set. It is denoted by n.
we have given that , n = 3 and N = 10
Using the following formula for calculating the possible number of different samples of size 3 (without replacement) can be taken from a finite population of size 10.
Number of possible different samples of size n from Population size N = NCn = N!/n! (N-n)!
then we have, 10C3 = 10!/3! × 7!

So, 4 weeks = 4*7 = 28 days.
In 1 day baby drinks = 22 ounce
In 28 days baby drinks = 28*22 = 616 ounce.
1 quarts = 32 ounces.
So, 616 ounce = 616/32 = 19.25 quarts.
Answer:22.75
Step-by-step explanation: 26 x 7 x 4 = 728 ounces in 4 weeks
theres 32 ounces in a quart
so 728 over 32 will equal 22.75
what happens to the width of two-sided confidence interval as each of these attributes changes? - the confidence level increases - the sample size increases a. increases b. decreases
The width of two-sided confidence interval decreases as the sample size increases and increases as the confidence level increases.
Confidence interval : In Statistic, confidence interval is a range of estimates for unknown parameters.
The formula for the interval can be expressed as:
Confidence Interval (CI ) = X bar +_ Z( S/√n)
Where,
X bar ---> the sample mean
S ---> the sample standard deviation
n --> the sample size Z---> Z-value which comes from normal distribution
From the formula we can conclude the below points about confidence interval :
The increases in confidence level leds to increase the width of the confidence interval also. A larger confidence level means the interval is larger. the width of confidence interval varies inversely to sample size i.e increase in sample size implies decrese in width of confidence interval. .Confidence interval increases with increase of sample standard deviationsSo, Confidence interval varies with sample mean, confidence level and standard deviations.
