Answers
The inequality describes the problem of a local ice cream shop has a parking lot with enough space for 18 cars is x + 7 ≤ 18
What is an Inequality?In mathematics, an inequality describes a relationship between two values of an algebraic expression that are not equal. “If two real numbers or the algebraic expressions are related by the symbols “>”, “<”, “≥”, “≤”, then, this relationship is called an inequality." For example, x>8 (x should be greater than 8).
We have, a local ice-cream shop has a parking lot with enough space.
The maximum number of cars will be parked in parking lot = 18.
At right now, the number of cars in parking lot= 7. Let assume that x be number of more cars can park in the lot. We have to express this in form of an Inequality. Total cars in parking lot = 7 + x but this number of cars cannot exceed the 18 , so x + 7 ≤ 18
Hence, required Inequality is x + 7 ≤ 18.

The test scores for
the 10 boys in a class
are
78
5879
45 39
The mean score for
the 5 girls in the class
is 8
Calculate the mean
for this class.
Answers
Answer: The mean score for this class is 17.13.
Step-by-step explanation:
Add up all of the scores for the boys: 78 + 58 + 79 + 45 + 39 = 249
Add the mean score for the girls: 249 + 8 = 257
Add up the number of students in the class: 10 + 5 = 15
Divide the total score by the number of students to find the mean: 257 / 15 = 17.13
What do you understand by mean and how many methods are there to find it ?
Mean is a statistical term that refers to the average value of a set of data. There are two main methods for finding the mean:
Arithmetic mean: This is the most common method of calculating the mean. It is simply the sum of all the values in the set of data, divided by the number of values in the set.
Geometric mean: This method is used when the data set includes both positive and negative values. It is the nth root of the product of all the values in the set, where n is the number of values in the set.
There are also other methods for finding the mean, such as the harmonic mean, the weighted mean, and the trimmed mean, but these are less commonly used.
To find the mean score for the entire class, we need to add up all of the scores and divide by the total number of students. First, let's start by adding up all of the scores for the boys. We have: 78+58+79+45+39 = 249
Next, let's add the mean score for the girls, which is 8.
So the total is now: 249 + 8 = 257.
Now we need to divide this total by the number of students in the class to find the mean score. There are 10 boys and 5 girls in the class, for a total of 10 + 5 = 15 students.
Therefore, the mean score for this class is :
257/15 = 17.13.

Determine if x and y are inversely proportional. If applicable, find the constant of variation.
Answers
Answer:
x and y are inversely proportional , constant of proportion k = 30
Step-by-step explanation:
If x and y are inversely proportional then the equation relating them is
y = [tex]\frac{k}{x}[/tex] ← k is the constant of proportion
multiply both sides by y , then
k = xy
to check that k is constant use the ordered pairs from the table
(0.1, 300 )
k = 0.1 × 300 = 30
(0.5, 60 )
k = 0.5 × 60 = 30
(75, 0.4 )
k = 75 × 0.4 = 30
(100, 0.3 )
k = 100 × 0.3 = 30
thus x and y are inversely proportional with constant of proportion k = 30

Answer: b) increasing
Step-by-step explanation: It seems evident that the sequence is made up of all the odd numbers.
[tex]\begin{gathered} \bold{a_1=1}\\ \bold{a_2=3=a_1+2}\\ \bold{a_3=5=a_2+2}\\ \bold{a_4=7=a_3+2} \\ \bold{a_n=a_{n- 1}+2}\end{gathered}[/tex]
As we can see, in the nth position (any position), we take the value of the previous position and add 2 to it. This leads us to conclude that the sequence is monotonic increasing since as we add 2 to the values, these grow up.

solve the equation by factoring x^2-4x=12
Answers
Answer:
x = - 2 , x = 6
Step-by-step explanation:
x² - 4x = 12 ( subtract 12 from both sides )
x² - 4x - 12 = 0 ← in standard form
to factor, consider the factors of the constant term (- 12) which sum to give the coefficient of the x- term (- 4)
the factors are - 6 and + 2 , since
- 6 × 2 = - 12 and - 6 + 2 = - 4 , then
(x + 2)(x - 6) = 0 ← in factored form
equate each factor to zero and solve for x
x + 2 = 0 ⇒ x = - 2
x - 6 = 0 ⇒ x = 6
imagine that two friends (heather and suzanne) are playing a video game where the player goes on quests to earn coins. the average number of coins earned on a quest is 2000. heather plays quite a bit, and goes on an average of 20 quests a day. suzanne doesn't play quite as much, and only goes on 5 quests a day. on a particular day, which person is less likely to record an average earning below 1500 coins?
Answers
When two friends are playing a video game where the player goes on quests to earn coins with an average number of 2000 coins earned in a quest, if one plays an average of 20 quests a day and other play 5 quests a day, none of them are likely to record an average earning below 1500 coins in a day.
Therefore the answer is both Heather and Suzanne are less likely to record an average earning below 1500 coins.
Here the average number of coins earned in a quest is not dependent on the number of quests played in a day. So for both Heather and Suzanne the average earning is to be 2000, so they are less likely to earn below 1500 coins.

What if tan angle is negative?In trigonometric mathematics, this expression is known as the tangent of negative angle identity.Tan of negative angle identity is a mathematical relationship between the tangents of a negative and positive angle.Formulatan(-∅) = - tan∅
Proof : By using a geometrical approach in trigonometry, the mathematical relationship between the tangent of a negative angle and the tan of a positive angle is obtained.Construction of triangle with negative angle : Create the same triangle with a negative angle. As a result, QOR has a negative theta angle, represented by -∅.Write the tan of the negative angle in terms of the ratio of the lengths of the respective sides based on this information.tan (- ∅) = QR / OQ
The length of the opposite side will be yet the length of the adjacent side will be due to the building of the triangle with negative angle.=> tan (- ∅) = -y /x.

Larry started playing a video game and was knocked out in 30 seconds. He then decided to play again and this time he was able to play 30 seconds longer than the previous game. He kept repeating this and was able to play 30 seconds longer each time. Since it cost him 25 cents to play each game, it will therefore cost him $1.00 to last 4 minutes before he is knocked out.
