When three standard six-faced dice are rolled, the probability that the sum of the three numbers rolled is 9 is equal to 10/216 or 5/108.

Total number of ways three dice can be rolled = 6 × 6 × 6 = 216.

Each dice can have any number from 1 to 6. The probability of rolling a particular number on a dice = 1/6.

The probability of rolling a particular number on three dice = (1/6) × (1/6) × (1/6) = 1/216.

In order to get a sum of 9, there are four combinations that can be rolled:

3 + 3 + 3 = 9

3 + 4 + 2 = 9

3 + 5 + 1 = 9

4 + 3 + 2 = 9

The probability of rolling any of these combinations = probability of rolling 3-3-3 + probability of rolling 3-4-2 + probability of rolling 3-5-1 + probability of rolling 4-3-2

= (1/216) + (3/216) + (3/216) + (3/216)

= 10/216 or 5/108.

The  values of x will f(x) > 0 for x < 0, and f(x) < 0 for -6 < x < 0 and x > -6.

To determine the values of x for which f(x) > 0, we need to find the intervals where the function is positive. Let's analyze the function f(x) = x*-x³-6x².

First, let's factor out an x from the expression to simplify it: f(x) = x(-x² - 6x).

Now, we can observe that if x = 0, the entire expression becomes 0, so f(x) = 0.

Next, we analyze the signs of the factors:

1. For x < 0, both x and (-x² - 6x) are negative, resulting in a positive product. Hence, f(x) > 0 in this range.

2. For -6 < x < 0, x is negative, but (-x² - 6x) is positive, resulting in a negative product. Therefore, f(x) < 0 in this range.

3. For x > -6, both x and (-x² - 6x) are positive, resulting in a negative product. Thus, f(x) < 0 in this range.

Answer:

s7= -7

Step-by-step explanation:

a0 is the regression term that describes the constant or intercept in the linear regression equation.

In a simple linear regression model, the equation takes the form of y = a0 + a1x + e1, where y is the dependent variable (or response variable), x is the independent variable (or predictor variable), a0 is the intercept or constant term, a1 is the coefficient of the independent variable, and e1 is the error term.

The intercept term, a0, represents the value of the dependent variable when the independent variable is zero. For example, in a linear regression model that predicts salary based on years of experience, the intercept would represent the starting salary for someone with zero years of experience. The intercept is an important component of the regression equation because it allows us to make predictions for values of x that are outside the range of our observed data.

The coefficient, a1, represents the change in the dependent variable for each one-unit increase in the independent variable. In the salary example, the coefficient would represent the average increase in salary for each additional year of experience.

Both the intercept and coefficient are estimated from the data using methods such as least squares regression. Once these values are estimated, we can use them to make predictions for new values of x.

Yes, triangle inequality theorem apply to all equilateral triangles.

The triangle inequality theorem explains the relation between a triangle's three sides. This theorem states that for any triangle, the sum of the lengths of the first two sides is always greater than the length of the third side. In other terms, this theorem states that a straight line is always the shortest distance between any two places.

So Triangle inequality theorem is not only valid for all equilateral traingles but it is valid for all traingles.

The Vertex form of the equation 6x²+12x+y+13=0 is y = -6(x+1)²-7

The vertex form of the equation y=ax²+bx+c can be written as

y = a(x-h)²+k

where h= -b/2a ,

and k = ah²+bh+c

In the question ,

the equation is given as

6x²+12x+y+13=0

Rewriting the equation , we get

y = -6x²-12x-13

So , the value of a = -6 , b = -12 and c = -13

Substituting the values , to find h ,

we get

h = -(-12)/2(-6)

h = 12/(-12)

h = -1

Substituting the value of h, a, b, c in the formula of k ,

we get ,

k = -6(-1)² -12(-1) -13

= -6*1 +12 -13

= -6 -1

= -7

Substituting the value of h and k to find the vertex form of the equation we get ,

21 bags are not full.

Step-by-step explanation:

Given that,

Total no. of marbles = 395

He is putting 22 marbles in each bags.

We need to find the number of marbles will he have in the bags that is not full. It can be calculated by dividing total no. of marbles and the no. of marbles in each bags.

\(x=\dfrac{395}{22}\\\\=17.95\\\\\text{or}\\\\=17\dfrac{21}{22}\)

So, it means 17 bags are full but 21 bags are not full.

The labor efficiency variance for the month can be calculated by comparing the standard labor hours allowed for the actual output to the actual labor hours worked. The labor efficiency variance for the month is 1,780 hours.

The labor efficiency variance is a measure of the efficiency of labor utilization in the production process. It reflects the difference between the standard labor hours allowed for the actual output and the actual labor hours worked. To calculate the labor efficiency variance, we need to determine the standard labor hours allowed for the actual output and subtract the actual labor hours worked.

In this case, the standard labor hours per unit of output is given as 8.4 hours, and the actual output for the month is 950 units. Therefore, the standard labor hours allowed for the actual output would be 8.4 hours/unit * 950 units = 7,980 hours.

The actual labor hours worked are given as 6,200 hours. To calculate the labor efficiency variance, we subtract the actual labor hours worked from the standard labor hours allowed for the actual output:

Labor Efficiency Variance = Standard labor hours allowed - Actual labor hours worked

= 7,980 hours - 6,200 hours

= 1,780 hours

The labor efficiency variance for the month is 1,780 hours. This indicates that the actual labor hours used were less than the standard labor hours allowed for the actual output, suggesting an efficiency gain in labor utilization.

Henry could only see one line since both lines had the same slope, which means that the graphs of both equations will be identical and hence overlap.

Linear equations in a system 3x + 2y = 4, and 9x + 6y = 12

We must demonstrate why Henry could only make out one line when he plotted the equations 3x-2y=4 and 9x-6y=12 on a graph.

Take the provided linear equation system into consideration.

3x - 2y = 4 ................(1)

9x - 6y = 12 ..................(2)

Due to the fact that equation (2) is a multiple of equation (1), 3 (3x - 2y = 4) = 9x - 6y = 12

The slopes of the provided equations are also same.

Difference with regard to x for equation (1) yields,

Segment BA, or side c, is opposite angle C

Segment AC, or side b, is opposite angle B

So we have this known info:

Apply the law of sines to find c. Make sure your calculator is in degree mode.

sin(B)/b = sin(C)/c
