Step-by-step explanation:

Given

6\(n^{4}\) - 24n³ + 18n ← factor out 6n from each term

= 6n(n³ - 4n² + 3) ← which may be factored further if required

6n(n³ - 4n² + 3)  is the factored form.

Expressions is the defined as mathematical statements that have a minimum of two terms containing variables or numbers.

Given that,

⇒6n⁴ - 24n³ + 18n

factor out 6n from each term

⇒6n(n³ - 4n² + 3)

There are two factors 6n and (n³ - 4n² + 3) of given expression.

Answer:

  in any numerical computation; numerical values can only be rational numbers

Step-by-step explanation:

Any time a number is written down as a numerical value, it is a rational number. The numerical values we give to π or e or any root, logarithm, trig function, and polynomial solution are, of necessity, rational approximations to the true value. An "exact" value for an irrational number cannot be written down, so it must be approximated any time its numerical value is needed.

Raina bought 46 yards of ribbon with her prepaid debit card.

To find out how many yards of ribbon Raina bought, we'll need to use the given information about the price of ribbon and the remaining balance on her prepaid debit card.
1. First, we need to determine how much money Raina spent on the ribbon. Since her card had $25 initially and there was $21.25 left on it after her purchase, we can subtract the remaining balance from the initial amount:
$25 - $21.25 = $3.75
Raina spent $3.75 on the ribbon.
2. Next, we'll use the price per yard to figure out how many yards she bought. We know that the ribbon cost 8 cents per yard, so we can divide the total cost by the price per yard to find out the number of yards purchased:
$3.75 ÷ $0.08 = 46.875 yards
Since Raina can't buy a fraction of a yard, we'll round this number down to the nearest whole yard:
46.875 yards ≈ 46 yards
Raina bought 46 yards of ribbon with her prepaid debit card.

The height of the cable is 0.15 meters and 1.35 meters at a point 200 meters and -200.

The given details are: Height of twin towers above road surface = h = 160 meters. Distance between twin towers = d = 800 meters. At the center of the bridge, the cables touch the road surface so the maximum height of the cable will be h. Using the formula for the parabolic cable we get: h(x) = a(x - d/2)(x + d/2). Let's find the value of "a" using the maximum height of the cable at the center of the bridge .i.e., h = a(0 - d/2)(0 + d/2) => h = a(d/2)^2 => a = (4h/d^2)Therefore, h(x) = (4h/d^2)(x - d/2)(x + d/2)We need to find the height of the cables at a point x meters from the center. Therefore, we need to find the value of h(x) when x = ±200 meters from the center of the bridge. h(x) = (4h/d^2)(x - d/2)(x + d/2) => h(x) = (4 × 160)/(800 × 800) (x - 800/2)(x + 800/2)When x = -200,h(-200) = (4 × 160)/(800 × 800) (-200 - 800/2)(-200 + 800/2)= (4 × 160)/(800 × 800) (-1200)(200)h(-200) = 0.15 meters. When x = 200,h(200) = (4 × 160)/(800 × 800) (200 - 800/2)(200 + 800/2)= (4 × 160)/(800 × 800) (-400)(1200)h(200) = 1.35 meters. Hence, the height of the cable is 0.15 meters and 1.35 meters at a point 200 meters and -200 meters from the center of the bridge respectively.

By applying independent and disjoint events theory, it can be concluded that A and B are neither disjoint nor independent (option D).

In probability, based on the occurrences, there are two types of events: independent and disjoint events.

Now we observe the data given:

p(a) = 0.3

p(b) = 0.2

p(a and b) = 0.4.

First, we check the independence. Here p(a and b) = 0.4. Whereas, if a and b are independent events, then:

p(a and b) = p(a) * p(b)

                = 0.3 * 0.2

                = 0.06

Since the value is different, we can conclude that events A and B are not independent.

Second, we check whether these events are disjoint events. Since the value of p(a and b) is not 0, these events are disjoint events.

Therefore, we can conclude that a and b are neither disjoint nor independent (option D)

Answer:

Step-by-step explanation:

Here, we want to graph the given equations

1. y = 2x - 3

The general form of the equation of a straight line is;

y = mx + b

m is the slope and b is the y-intercept

To plot the line, we need the x intercept and the y-intercept

At the x-intercept, the value of y is zero

at the y-intercept . the value of x is zero

From the equation, we have the y-intercept as -3

To get the x-intercept, set y = 0

0 = 2x - 3

2x = 3

x = 3/2

x = 1.5

so to graph the line, we have to join the points ;

(0,-3) and (1.5,0)

b) y = -3x + 2

The y-intercept is 2

To get the x intercept, set y = 0

0 = -3x + 2

3x = 2

x = 2/3

so, we have to join the points (2/3,0) and (0,2)

Option a,The correct null hypothesis for an independent-measures t test is option a, which states M1 - M2 = 0.

An independent-measures t test is a statistical test used to compare the means of two independent groups. In this test, the null hypothesis represents the assumption that there is no significant difference between the means of the two groups. The null hypothesis is usually expressed in terms of the difference between the means of the two groups, denoted by M1 and M2.

In summary, the correct null hypothesis for an independent-measures t test is option a, which states M1 - M2 = 0. This null hypothesis assumes that there is no significant difference between the means of the two groups and any observed difference is due to chance. Option b assumes a significant difference between the means, while options c and d use population means instead of sample means. It is important to correctly specify the null hypothesis in a statistical test to ensure that the conclusions drawn from the analysis are valid.

Answer:

We can start by isolating the variable "h".

5 8 h + 1 1 2 = 5

Subtracting 11/2 from both sides:

5 8 h = 5 - 1 1 2

Simplifying:

5 8 h = 8 1 2

Dividing both sides by 5/8:

h = 8 1 2 ÷ 5 8

Converting the mixed number to an improper fraction:

h = (8 x 8 + 1) ÷ 5 8

h = 65/8

Now, we can convert this fraction to a mixed number:

h = 8 1/8

Brigid has already picked for 8 1/8 hours, so the amount of time needed to pick the remaining strawberries is:

5 - (1 1/2 + 5/8 x 8) = 5 - (3 5/8) = 1 3/8

Therefore, Brigid still needs to pick for 1 3/8 hours to fill 5 bushels of strawberries. The answer is 1 and 3/8 hours or 2 and 3/16 hours (if simplified).

Step-by-step explanation:

3y + 2x = 44 is the equation of the line through (10, 8) and (4, 12).

A linear equation has the slope-intercept form y = mx + b. Variables in the equation are x and y. When x is 0, the integers m and b provide the line's slope (m) and the value of y. Because (0,y) is the location where the line crosses the y-axis, the value of y when x is 0 is referred to as the y-intercept.

Given, two coordinates of a line \(\left(10,8\right) and \left(4,12\right)\)

The slope of the line formula is:

\(m = \frac{y₂ - y₁}{ x₂ - x₁}\)

Let's substitute our numbers.

\(m = -\frac{8 -12}{4-10}\)  =  -4/6

The GCF of these two numbers is 2

So, our slope  =  -2/3

The general equation of a line is y = mx +c

Therefore the equation of the line is y = -2/3x + c

Since, this line passes through ( 10, 8 )

Hence, it must satisfy these coordinates

8 = -2/3 * 10 + c

44/3 = c

Thus the equation of the line is y = -2/3x +44/3

the equation of the line is 3y + 2x = 44.

Therefore, The equation of the line that passes through (10, 8) and (4, 12) is 3y + 2x = 44.
