The interval notation for the solution set is (-∞, -4] and the number line is on the image at the end.

Here we want to find the solution set of the inequality below:

x ≤ -4

First let's do the interval notation. This will be the set that contains all the numbers from negative infinity to -4 (with -4 included, so  we need to have a closed set at that end)

This is written as:

(-∞, -4]

The use of the symbols [ ] means that the element belongs to the set.

Now to the number line, we will have a closed circle at x = -4 (because it is a solution) and a line that goes to the left of it. You can see an example in the graph at the end.

Answer: $5.00

Step-by-step explanation:

The cost of a 6-mile ride is made up of three components: a base fare of $1.25, a distance charge of 50 cents per mile, and a waiting charge of 30 cents per minute for the time spent eating at stoplights.

The distance charge for a 6-mile ride is:

6 miles x $0.50/mile = $3.00

The waiting charge for 2.5 minutes at 30 cents per minute is:

2.5 minutes x $0.30/minute = $0.75

So the total cost of the ride is:

$1.25 (base fare) + $3.00 (distance charge) + $0.75 (waiting charge) = $5.00

Therefore, a 6-mile taxi ride with 2.5 minutes of waiting time at stoplights costs $5.00.

We must add the relevant components of each of the three vectors, X1, X2, and X3, in order to resultant vector the final vector XR, which has the components (1, -5)m.

R = A + B. Equation 2 To create the resultant vector, opposing vectors are subtracted from one another. R is the resulting vector in this case, and the column B is directed in the opposite direction to a vector A.

We must add the relevant components of each of the three vectors, X1, X2, and X3, in order to resultant vector the final vector XR, which has the components (1, -5)m.

To find the resultant vector, we need to add the corresponding components of the three given vectors. So, we have:

XR = X1 + X2 + X3

XR = (-2,0) m + (0,-5) m + (3,0) m

XR = (-2+0+3, 0+(-5)+0) m

XR = (1, -5) m

The probability that the casino's total profit will exceed $1000 is very close to zero.

The probability of winning a bet on red in American roulette is 18/38, and the probability of losing is 20/38.

Therefore, the expected profit for the casino on each bet is:

E(profit per bet) = (18/38) x ($1) + (20/38) x (-$1) = -$0.0526

The variance of the profit per bet can be calculated as follows:

Var(profit per bet) = (18/38) x ($1 - (-$0.0526))^2 + (20/38) x (-$1 - (-$0.0526))^2 = $0.921

The standard deviation of the profit per bet is the square root of the variance, which is approximately $0.960.

The expected profit for the casino from 25000 bets is:

E(total profit) = 25000 x (-$0.0526) = -$1315

The standard deviation of the total profit is the square root of the variance multiplied by the number of bets, which is approximately $305.46.

To find the probability that the casino's total profit will exceed $1000, we can standardize the distribution of the total profit as follows:

z = (1000 - (-$1315)) / $305.46 = 9.48

Using a standard normal table or calculator, we can find that the probability of a standard normal variable exceeding 9.48 is essentially zero.

Answer:

The terms 2x and -5x are like terms.

Step-by-step explanation:

Like terms are terms that have the same variable(s) raised to the same power(s). In this case, both 2x and -5x have the same variable "x" raised to the same power "1". The only difference between them is the coefficient, which is 2 for 2x and -5 for -5x. However, the coefficients do not affect whether two terms are like or unlike terms.

So, because 2x and -5x have the same variable raised to the same power, they are like terms.

Answer:

If we want to choose 6 objects out of 14 objects and the order does not matter, then the number of ways we can do this is 3003.

The number of ways you can select or organize objects is defined by formulas of permutation and combination. Choosing one or the other depends on whether the order matters (permutation) or not (combination). In this case, as the order does not matter, the general formula is:

C  = n! / r! (n-r)!

In this formula, n is the total of items and r is the total I need to select. Let's then solve it:

C= 14! / 6! (14! - 6!)

C = 14! / 6! 8!

C= 14 x 13 x 12 x 11 x 10 x 9 / 6 x 5 x 4 x 3 x 2

Thus, estimated margin of error is 0.4.  Sample mean height of seedlings is 4.5 cm.

The degree of error in survey findings from random sampling is known as the margin of error in statistics. A wider margin of error for statistics denotes a reduced possibility of relying on a survey's or poll's findings, meaning that there will be less confidence in the results' ability to accurately reflect a community.

In order to admit that sample findings will vary between sample to sample and may differ from the actual population situation, you must add a margin of error to your statistical results.

Given data:

confidence interval of (4.1,4.9)

upper limit k = 4.9.

Lower limit r = 4.1.

So,

margin of error E = (k - r)/2

E = (4.9 - 4.1)/2

E = 0.4

Thus, estimated margin of error is 0.4.

Answer:

Option B

Step-by-step explanation:

To find the standard deviation, we need to follow these steps:

1) Find the mean of the data set.

2) Calculate the difference between each data point and the mean.

3) Square each difference.

4) Find the average of the squared differences.

5) Take the square root of the average to get the standard deviation.

First, we find the mean of the data set:

Mean = (7.2 + 8.9 + 2.7 + 11.6 + 5.8 + 10.2) / 6 = 46.4 / 6 = 7.73

Next, we calculate the difference between each data point and the mean:

| 7.2 - 7.73 | = 0.53

| 8.9 - 7.73 | = 1.17

| 2.7 - 7.73 | = 5.03

| 11.6 - 7.73 | = 3.87

| 5.8 - 7.73 | = 1.93

| 10.2 - 7.73 | = 2.47

Then, we square each difference:

0.53^2 = 0.2809

1.17^2 = 1.3689

5.03^2 = 25.3009

3.87^2 = 14.9569

1.93^2 = 3.7249

2.47^2 = 6.1009

Next, we find the average of the squared differences:

(0.2809 + 1.3689 + 25.3009 + 14.9569 + 3.7249 + 6.1009) / 6 = 8.62

Finally, we take the square root of the average to get the standard deviation:

sqrt(8.62) = 2.93

Therefore, the standard deviation of the data set is 2.93, which is option B.

Answer:

Step-by-step explanation:

Because this is a right triangle the two angles besides the right angle add up to 90°

33 + 3x + 9 = 90

Combine like terms

42 + 3x = 90

Isolate the x ( subtract 42 from both sides)

3x = 48

Divide both sides by 3

x = 16

Answer:

X= 16

Step-by-step explanation:

right angle = 90°

And we have 33° already

90 + 33 = 123

Triangle is 180

180 - 123 = 57

Write in an equation

57 = 3x + 9

57- 9 = 48

48= 3x

48/ 3 = 16

the values of x where f(x) = 1 for the function y = x^2 - 2x + 1 are x = 0 and x = 2.

general steps to find all values of x where f(x) = 1 for a given function y = f(x):

1. Set f(x) equal to 1: f(x) = 1.
2. Solve the equation for x. This may involve algebraic manipulation or using techniques such as factoring, completing the square, or using the quadratic formula, depending on the form of the equation.
3. If the equation has multiple solutions, list them all as the values of x where f(x) = 1. If the equation has no solutions, then there are no values of x for which f(x) = 1.

For example, if the function is y = x^2 - 2x + 1, then setting f(x) = 1 gives:

x^2 - 2x + 1 = 1

Simplifying this equation by subtracting 1 from both sides, we get:

x^2 - 2x = 0

Factoring out x, we get:

x(x - 2) = 0

This equation is satisfied when either x = 0 or x = 2. Therefore, the values of x where f(x) = 1 for the function y = x^2 - 2x + 1 are x = 0 and x = 2.

the area of one of the isosceles triangles formed by cutting the square by a diagonal is 25√(7) square cm.

Find the area of triangle?

To find the area of one of the isosceles triangles formed by cutting the square by a diagonal, we can use the fact that the area of a triangle is given by the formula:

A = (1/2)bh

where A is the area of the triangle, b is the base, and h is the height.

In this case, the base of the isosceles triangle is one of the sides of the original square, which is 10 cm. The height can be found by using the Pythagorean theorem, since the diagonal of the square and the height of the isosceles triangle form a right triangle:

d² = h² + (10/2)²

where d is the length of the diagonal, which can be found using the Pythagorean theorem:

d² = 10² + 10² = 200

d = √(200) = 10√(2)

Substituting this value for d in the first equation, we get:

(10√(2))² = h²+ (10/2)²

200 = h² + 25

h²= 175

h = √(175) = 5√(7)

Now we can use the formula for the area of a triangle to find the area of one of the isosceles triangles:

A = (1/2)(10)(5√(7))

A = 25√(7) square cm

Therefore, the area of one of the isosceles triangles formed by cutting the square by a diagonal is 25√(7) square cm.
