The inequality is graphed on the number line is

Inequality can be graphed on a number line by shading the appropriate region of the number line.

To graph an inequality x > -7, follow these steps:

Plot the critical points on the number line. The critical points are the values of x that make the inequality true with an equal sign. For example, to graph the inequality x > -7, we plot the critical point x = -7 on the number line.

Determine the direction of the shading or line. If the inequality is "greater than" or "greater than or equal to," shade to the right of the critical point..

If the inequality includes "or equal to," use a closed circle at the critical point. If the inequality does not include "or equal to," use an open circle at the critical point.

Answer:

28%

Step-by-step explanation:

Let's assume that there are 2x girls and 3x boys in the school, as given the ratio of girls to boys is 2:3. Therefore, the total number of students in the school is 5x.

According to the problem, 25% of the girls have school dinners. So, the number of girls having school dinners is 0.25*2x = 0.5x.

Similarly, 30% of the boys have school dinners. So, the number of boys having school dinners is 0.3*3x = 0.9x.

Therefore, the total number of students having school dinners is 0.5x + 0.9x = 1.4x.

The percentage of students having school dinners can be found by dividing the total number of students having school dinners by the total number of students in the school and multiplying by 100%.

So, the percentage of students having school dinners is (1.4x/5x) * 100% = 28%.

Hence, the total percentage of students at the school who have school dinners is 28%.

To verify the answer, let's consider a numerical example.

Let's assume there are 200 students in the school, out of which 2/5 (i.e., 40%) are girls and 3/5 (i.e., 60%) are boys.

According to the problem, 25% of the girls have school dinners, which is 0.25 * 2/5 * 200 = 20 students.

Similarly, 30% of the boys have school dinners, which is 0.3 * 3/5 * 200 = 36 students.

Therefore, the total number of students having school dinners is 20 + 36 = 56.

The percentage of students having school dinners is (56/200) * 100% = 28%.

Hence, the answer is verified.

A student who does not have a sister has a 2/9 chance of having a brother.

What exactly is probability?

Probability is a measure of an event's possibility or chance of occurring. It's a number between 0 and 1, with 0 indicating an impossible event and 1 indicating a certain event. The probability of an occurrence is estimated by dividing the number of possible outcomes by the number of ways the event might occur.

Consider the following events:

"Has a brother"

"Doesn't have a sister," says B.

The probability of occurrence A given event B is written as P(A|B). We can use Bayes' theorem to write:

P(A|B) equals P(B|A) * P(A) / P(B).

where P(B|A) represents the probability of not having a sister given that the student has a brother, P(A) represents the probability of having a brother (equal to the proportion of students who have a brother), and P(B) represents the probability of not having a sister (equal to the proportion of students who do not have a sister).

We can use the table values to fill in the blanks:

P(B|A) = 2 / (5 + 2) = 2/7

P(A) = (5 + 2) / (5 + 2 + 9 + 7) = 7/23

P(B) = (2 + 7) / (5 + 2 + 9 + 7) = 9/23

Plugging these values into the formula, we get:

P(A|B) = (2/7) * (7/23) / (9/23) = 2/9

Therefore, A student who does not have a sister has a 2/9 chance of having a brother.

When both t and d are zero, we can immediately see that c = 0 because the train begins at rest. Additionally, the rate of change is the constant speed, making m = 95. Thus, d = 95t is the necessary relationship.

A graph is a type of data structure that consists of edges and nodes (vertices). It is a non-linear data structure intended to depict connections between things, occasions, or concepts. Graphs are frequently used to represent numerous forms of data in computer science, mathematics, engineering, and other disciplines. A wide range of data sets, including networks, social relationships, and even biological systems, can be represented using graphs. Graphs can also be used to spot trends, correlations, and patterns in data.

The necessary equation should be d = mt +c,

Where the arbitrary real constants m and c are used.

When t = 1, d = 95

so that 95= m+c ---> (1)

Also, when t=2, d = 190,

hence 190 = 2m+c ---> (2)

When the first equation is taken out and the second equation is added back in,

we get 2m+c-m-c = 190-95 or, m = 95.

When this value of m is substituted in the first equation,

we get 95 = 95+c so that c = 95-95 = 0.

Thus, the require3d equation is d = 95t. Since 95*3 = 285 and 95*4= 380, All of the given facts are satisfied by this equation.

Inequality in standard form:

5x² - 40x - 45 ≤ y ≤ x² + 8x + 9 and y ≤ x² - 8x - 9 and y ≥ 5x² + 40x + 45

What is inequalities?

In mathematics, an inequality is a mathematical statement that indicates that two expressions are not equal.

To find the inequality that represents the shaded region, we can first simplify each inequality and then combine them using "and" or "or" operators as necessary.

Starting with each inequality:

y ≥ x² + 8x + 9: This is a parabola that opens upwards and has a vertex at (-4,1). The inequality means that all points above or on the parabola are included in the shaded region.

y ≥ x² - 8x - 9: This is a parabola that opens upwards and has a vertex at (4,-1). The inequality means that all points above or on the parabola are included in the shaded region.

y ≤ 5x² - 40x - 45: This is a parabola that opens upwards and has a vertex at (4,-125). The inequality means that all points below or on the parabola are included in the shaded region.

y ≥ 5x² + 40x + 45: This is a parabola that opens upwards and has a vertex at (-4,-125). The inequality means that all points above or on the parabola are included in the shaded region.

Combining the inequalities using "and" or "or" operators:

Since all of the inequalities have "y ≥" or "y ≤" in them, we know that the shaded region is above or below some combination of the parabolas. Specifically, the shaded region is above the first two parabolas and below the second two parabolas. Therefore, we can use "and" to combine the inequalities as follows:

y ≥ x² + 8x + 9 and y ≥ x² - 8x - 9 and y ≤ 5x² - 40x - 45 and y ≤ 5x² + 40x + 45

This gives us the final inequality in standard form:

5x² - 40x - 45 ≤ y ≤ x² + 8x + 9 and y ≤ x² - 8x - 9 and y ≥ 5x² + 40x + 45

Note that we flipped the direction of the inequality for the last term (y ≥ 5x² + 40x + 45) to make it consistent with the other three inequalities.

The engineer should consider a sample size of 325 electronic components to be 90% sure that the mean width will be within ± 0.3 mm.

To determine the required sample size, we can use the formula for the margin of error (ME) in the context of the normal distribution:

ME = (Z * σ) / √n

Where:

ME = Margin of error

Z = Z-score, which corresponds to the desired level of confidence (in this case, 90%)

σ = Standard deviation (3.3 mm in this problem)

n = Sample size

First, we need to find the Z-score corresponding to a 90% confidence level. This can be found using a Z-table or statistical software. The Z-score for a 90% confidence interval is approximately 1.645.

Now, we will rearrange the formula to solve for the sample size (n):

n = (Z * σ / ME)^2

We are given that the margin of error should be within ± 0.3 mm:

n = (1.645 * 3.3 / 0.3)^2

n ≈ (18.015)^2

n ≈ 324.54

Since we cannot have a fraction of a component, we round up to the nearest whole number to ensure the desired level of confidence:

n ≈ 325

The engineer should consider a sample size of 325 electronic components to be 90% sure that the mean width will be within ± 0.3 mm.

The distance from point C to A that is AC = 7.5 cm and CB = 10.5 cm.

While distance and displacement appear to have the same meaning, they actually have very different definitions and implications. Displacement is the measurement of "how far an object is out of place," whereas distance refers to "how much ground an object has covered during its motion."

Distance is the sum of an object's movements, regardless of direction. Distance can be defined as the amount of space an object has covered, regardless of its starting or ending position.

Let us suppose the distance between C to A = x.

Now, for C to B we have = 3 + x

Given, AB = 18

Thus,

AC + CB = AB

x + (x + 3) = 18

2x + 3 = 18

2x = 15

x = 7.5

What is the rate?

In mathematics, the rate is a measure of the change in one quantity with respect to another quantity. It is typically expressed as a ratio between the two quantities.

The initial population is 2.33 × 10¹.

After one year, the population will be:

P₁ = 2.33 × 10¹ + 0.07 × 2.33 × 10¹

P₁ = 2.33 × 10¹ (1 + 0.07)

After two years, the population will be:

P₂ = P₁ + 0.07 P₁

P₂ = P₁ (1 + 0.07) = 2.33 × 10¹ (1 + 0.07)²

After three years, the population will be:

P₃ = P₂ + 0.07 P₂

P₃ = P₂ (1 + 0.07) = 2.33 × 10¹ (1 + 0.07)³

And so on, until after six years:

P₆ = 2.33 × 10¹ (1 + 0.07)⁶

Simplifying the expression, we get:

We are given the line 6x+20y=17, and we want to write it in slope-intercept form.

Slope-intercept form is given as y=mx+b, where m is the slope and b is the value of y at the y-intercept, hence the name.

As we can see, in slope-intercept form, y is by itself on one side. So, we should solve the equation for y.

To do that, we can start by subtracting 6x from both sides.

6x + 20y = 17

-6x             -6x
