An inequality that shows how much faster Elanor can drive without going over the speed limit is 43.5 + s ≤ 55.
Elanor can increase her speed by 2.
How to write, solve, and graph the required inequality?In order to write and solve an inequality that represents how much faster Elanor can drive without going over the speed limit, we would take note of the following important information;
The maximum speed limit is equal to 55.Elanor's speed is equal to 43.5.Let the variable s represent the safe speed.Now, we can write an inequality that represents the value of s for which the speed of Elanor is still safe as follows;
43.5 + s ≤ 55
By subtracting 43.5 from both sides of the inequality, we have the following:
43.5 - 43.5 + s ≤ 55 - 43.5
s ≤ 11.5

What are the steps to plotting points on a coordinate plane?.
To plot a point in a coordinate plane, first we have to define the point, then determine the coordinates, both x and y coordinates. Then plot the point in the appropriate plane.
A point is usually in a coordinate plane is described by two axis, X and Y. A point will usually be denoted as (x,y). From these values we have to determine where the point might be lying. If the x value is positive it is towards the right of 0 and negative it will be towards left. Y value become positive upwards and negative downwards.
After determining the coordinates we label as the readings the the X axis and Y-axis. In the figure given below we have plotted some points.
Point A (2,2) with x-coordinate 2 and y coordinate 2 , B(4,-2) with x coordinate 4 and y coordinate -2, C(-3,-1) with x coordinate -3 and y coordinate -1, D(-2,3) with x coordinate -2 and y coordinate 3.
So, for plotting we have to determine the coordinates and plot it.

What is an algebraic expression with more than 3 terms?.
An algebraic expression with more than 03 terms is known as Multinomial.
Multinomial Distribution:
In probability theory, the multinomial distribution is a generalization of the binomial distribution. For example, model the probability of counting on each side of a k-sided die n tosses. For n independent trials, each succeeds in exactly one of the k categories, and each category has a certain fixed probability of success. A multinomial distribution gives the probability for each particular combination of numbers of successes in different categories.
If k is 2 and n is 1, the multinomial distribution is Bernoulli. If k is 2 and n is greater than 1, the distribution is binomial. If k is greater than 2 and n is 1, the distribution is categorical. The term "multinoulli" is sometimes used for categorical distributions to emphasize this four-way relationship (hence n determines the prefix and k determines the suffix).

The theater sells two types of tickets: adult tickets for $11 and child tickets for $3.
Last night, the theater sold a total of 464 tickets for a total of $3520. How many adult tickets did the theater sell last night?
The adult tickets sold were 409.
What number of total adult ticket were sold?11a + 3c = 3520
Where "a" is the number of adult tickets sold and "c" is the number of child tickets sold.
We also know that the theater sold a total of 464 tickets, so we can add the following equation:
a + c = 464
We can now use the first equation to solve for one of the variables, and then substitute it into the second equation:
11a + 3c = 3520
3c = 3520 - 11a
c = (3520 - 11a)/3
We know that:
a + c = 464
We can substitute the value of c into this equation:
a + (3520 - 11a)/3 = 464
a + (3520 - 11a) = 464*3
a + 3520 - 11a = 1392
12a = 4912
a = 4912/12
a = 409
So, the theater sold 409 adult tickets last night

I can only use numbers, infinity symbols, etc.
You have to consider the following relation.
Answer:
Domain:
[tex] - \infty < x < \infty [/tex]
Range:
[tex] - 1 \le \: y < \infty [/tex]
Step-by-step explanation:
Domain:The Domain of a function is x values which are included in the graph. Sometimes x values will not be included because they cannot be defined at that point, but in this case the graph indicates that the graph continues to the right and left with no indication that there is an asymptote or it is undefined beyond the graph so we can assume it's defined for all real numbers. We can represent this in interval notation as:
[tex] - \infty < x < \infty [/tex]
Since if you plug in any real number, this inequality should be true.
Range:The range of a function is defined as y values which are on the graph, this is restricted when certain y values are not on the graph... but we can usually tell because functions will have a minimum/maximum. By looking at the graph it appears to reach a minimum at y = -1 and then on the right and left side is increasing, never going below this value, so the range can be defined as:
[tex] - 1 \le y < \infty [/tex]
Since the y values vary between -1 (including -1) and infinity... well that really just means there's no upper bound and it just keeps increasing and increasing.

(c) What percentage of organs weighs less than 240 grams or more than 380 grams? (d) What percentage of organs weighs between 240 grams and 415 grams?
a) About 99.7% of organs will be between 205 grams and 415 grams.
b) The percentage of organs weighing between 240 grams and 380 grams is of 95%.
c) The percentage of organs less than 240 grams or more than 380 grams is of 5%.
d) The percentage between 240 grams and 415 grams is of: 97.35%.
What is defined by the Empirical Rule?These approximate percentages are defined by the Empirical Rule, for a normally distributed variable:
68% of the measures within one standard deviation of the mean.95% of the measures within two standard deviation of the mean.99.7% of the measures within three standard deviation of the mean.The first three questions are quite straight forward, while for the fourth we consider the symmetry of the normal distribution, as follows:
95% of 50% of the measures are between 240 grams and 310 grams.99.7% of 50% of the measures are between 310 grams and 415 grams.Hence the total percentage is of:

The sampling distribution of the sample mean for samples of size 16 is made up of V3.2 pets, which is the same as the average number of pets owned by the population of high school students.
We use sampling distribution because...
The sampling distribution is the probability distribution of a statistic obtained from a larger sample size drawn from a particular population. The sampling distribution of a particular population is the frequency distribution of a set of possible outcomes for a population statistic.The sampling distribution is the probability distribution of a statistic that is created by drawing numerous samples from a particular population. Researchers use sample distributions to simplify the statistical inference process.A large high school's student population has an average of 3.2 pets per student, with a standard deviation of 1.7 pets. A random sample of 16 students will be selected, and the mean number of pets for the sample will be calculated in order to better understand this population.This will give us the sample mean for samples of size 16 and the mean of the sampling distribution.To determine this, we must first determine the standard error of the mean, which is the sample mean's standard deviation. This is calculated by multiplying the sample size (16) by the square root ofthe population standard deviation (1.7 pets), yielding a standard error ofthe mean.Learn more about Sampling distribution refer to :

What is distributive property of equality?.
The distributive property of equality states that the product of an expression and a sum is equal to the sum of the products of the expression and each term in the sum.
Distributive Property of equality : Distribution in mathematics means multiplying an element by two or more additive elements in parentheses.
Multiplying the set by the sum of two terms is the same as adding the products of the original set and each term. In other words, multiplying a quantity by the sum of two or more terms is the same as adding the product of original quantity and each term. A simpler way of expressing this is that the equality holds after the distribution of the terms. Let a, b, and c be real numbers. Then: a(b + c) = ab + ac. A more general formulation is to let be natural numbers and a, b₁, b₂, b₃,---, bₙ be real numbers. Then, a( b₁+b₂+ b₃ +---+ bₙ) = ab₁ + ab₂ + ab₃ + ----+bₙ.

Answer:
32.9 cm^2
Step-by-step explanation:
In the absence of a diagram, lets use the one shown in the attached worksheet. The assumption is that the "blue areas" are the four sections of the circle that extend beyond the square boundaries. The approach is to calculate areas for both the circle and the square.
Square = (11 cm)^2 = 121 cm^2
Circle = (3.14)*(14/2 cm)^2 = 153,9 cm^2
Subtract the square from the circle. That removes all the circle area, except for the four sections outside the square. The result is 32.9 cm^2
A fair die is rolled 5 times. What is the probability of having no 1 and no 2 among the rolls
Answer:
40%
Step-by-step explanation:
There are 5 options to roll: 1, 2, 3, 4, and 5.
This means you have a 1 out of 5 chance of rolling each number.
This question is asking for 1 AND 2, not just one number. So, we have a 2 out of 5 chance of rolling that, because 2 options are acceptable instead of just one number.
I'm not sure which form you are looking for, but 2 out of 5 is the same as saying 2/5. Most probability solutions are wanted as a percentage. To find that just solve 2/5, which is 0.4. Move the decimal to the right twice, and that is a 40% chance.

M) a car is travelling at 29 mph. if the tires have a diameter of 25 inches, how fast are the cars tires turning? express answer in revolutions per minute
Answer:
To calculate the speed of the car's tires turning, you need to first calculate the circumference of the tire. If the tire has a 25 inch diameter, multiply 25 by 3.1416 to find the tire circumference, which is 78.54 inches. Now, divide 63,360 inches per mile by the tire circumference (78.54) to find the revolutions per mile, which is 803.6. Finally, multiply 803.6 by 29 (the speed of the car in mph) to get the revolutions per minute, which is 23,253.6. Therefore, the car's tires are turning at a rate of 23,253.6 revolutions per minute.

On solving the linear equations y = -2x + 6 and y = 5x - 8, the value for x is x = 2 and the value of y is y = 2.
What is a linear equation?
A linear equation is one that has a degree of 1 as its maximum value. No variable in a linear equation, thus, has an exponent greater than 1. A linear equation's graph will always be a straight line.
The first linear equation is - y = -2x + 6
The second linear equation is - y = 5x - 8
Subtracting equation (1) from (2) -
y - y = 5x - 8 - (-2x + 6)
0 = 5x - 8 + 2x - 6
0 = 7x - 14
7x = 14
x = 14/7
x = 2
Substituting the value of y in equation (1) -
y = -2x + 6
y = -2(2) + 6
y = -4 + 6
y = 2
The subtraction and substitution method is chosen to solve the system of linear equations. The linear equations are first made equal in order to find the desired variable. Then subtraction is done to find the value of one variable. Next, the found value is substituted into the equation to find the unknown variable. This method is easy to understand and gives accurate value.
Therefore, the value of x and y is 2 and 2 respectively.
