What is the sign of (-2)³? What is the sign of (-3)²? Justify your answers.
Answers
Based on the given bases with powers, the sign of (-2)³ is negative.
The sign of (-3)² can be found to be positive.
The justification for the signs can be found below.
How to find the sign?When multiplying two negative numbers, the result would be a positive number. When multiplying positive number by a negative number, the result would be negative.
(-2)³ is the same as -2 x -2 x -2 which is:
= -2 x -2 x -2
= 4 x -2
= -8
4 became positive but then became negative when multiplied by another -2.
(-3)² is 3 x 3:
= 3 x 3
= 9

To rent a certain meeting room, a college charges a reservation fee of $19 and an additional fee of $6 per hour. The chemistry club wants to spend at most $67
on renting the room. What are the possible numbers of hours the chemistry club could rent the meeting room?
Use t for the number of hours.
Write your answer as an inequality solved for t.
Answers
By estimating the linear inequality, the possible numbers of hours the chemistry club could rent the meeting room exists 9 hours.
What is meant by Linear inequalities?In mathematics, an expression with uneven sides is referred to as an inequality. When a relationship leads to a non-equal comparison between two expressions or two numbers, it is referred to as an inequality in mathematics.
In this case, the equal sign "=" is replaced with any of the inequality symbols, such as greater than symbol (>), less than symbol (), greater than or equal to symbol (), less than or equal to symbol (), or not equal to symbol ().
Strict inequalities are denoted by the symbols "" and ">," whereas slack inequalities are denoted by "" and "". A linear inequality has the same appearance as a linear equation, but uses a different symbol to link the two expressions.
To rent a certain meeting room, a college charges a reservation fee of $19 - 16 and an additional fee of $6 per hour. The chemistry club wants to spend at most $67 - 70
Given that, college charges a reservation fee of $19 and an additional fee of $6 per hour.
The chemistry club wants to spend at most $67.
To estimate the possible numbers of hours the chemistry club could rent the meeting room:
The governing inequality is
19 + 6t < 67
The solution is
t < (67-19)/6
simplifying the above equation, we get
t = 8 hours.
Therefore, the value of t = 8 hours.

ABC, ABC is a right angle AB=3 units, and BC=2 units &ABC is dilated by a scale factor of 0.5 with point 8 as the center of dilation, resulting
in the image AABC. Which statement about AB is true?
OA AB is 15 units long but lies on a different line than AB
OB AB is 3 units long but lies on a different line than AB
OC AB is 3 units long and lies on the same line as AB
OD. AB is 1.5 units long and lies on the same line as AB?
Answers
Answer:
A'B' is 1.5 units long and lies on the same line as AB.
Step-by-step explanation:
If AB = 3 units, BC = 2 units and a scale factor of 0.5 is applied, then A'B = 3*0.5 = 1.5 and B'C = 2* 0.5 = 1. Given that the point B is taken as the center of dilation then, segments A'B lies on the same line as AB and B'C lies on the same line as BC.
A candy company developed a new consumer product that is expected to earn $3,000 in profit each year if consumer demand is low, $19,000 per
year if consumer demand is moderate, and $31,000 per year if consumer demand is high. The probability of low, moderate, and high demand is
35%, 45%, and 20%, respectively. Determine the expected monetary value (EMV) for the new product.
Answers
The most appropriate choice for probability and profit will be given by:
Expected monetary value is $15800
What is probability and profit?
Probability of an event is the chance of occurance of that event.
Probability can be obtained by Number of favourable outcomes divided by the total number of outcomes
Probability varies from 0 to 1.
If the selling price of an item is more than its cost price, difference between the selling price and the cost price gives the profit.
Profit if consumer demand is low = $3000
Profit if consumer demand is moderate = $19000
Profit if consumer demand is high = $31000
Probability of low demand = 35%
Probability of moderate demand = 45%
Probability of high demand = 20%
Expected monetary value = $([tex]3000 \times \frac{35}{100}+19000 \times \frac{45}{100}+ 31000 \times \frac{20}{100}\\[/tex])

[tex]\begin{gathered} P(X=5)=\binom{5}{5}(0.37)^5(1-0.37)^{5-5}= \\ P(X=5)=1\cdot(0.37)^5(1-0.37)^{5-5}= \\ P(X=5)=0.37^5\mleft(0.63\mright)^{5-5} \\ P(X=5)=0.0069343957 \end{gathered}[/tex]2) Note the binomial probability of that event happening is very very low.

What is division ?The act of repeatedly subtracting is called division. It functions in the opposite way to how multiplication works. Forming equal groups is how it is described. When dividing numbers, we split a larger number into smaller ones so that the product of the multiplication of those smaller numbers equals the larger number that was divided. As an illustration, 4 2 = 2. This knowledge can be expressed as the multiplication 2 x 2 = 4.
Given that :Square root of 225
225 = 3 × 75

You drive 2 hours to the lake. Driving home on the same route, you decrease your speed by 25
miles per hour, increasing your drive time by 2 hours. Write and solve an equation to find how
fast you were driving to the lake.
Equation:
Solution:
Answers
Velocity differs from speed. Distance divided by time is the dimension of speed.
The speed of the vehicle while driving from home to the lake was 50 miles per hour.
What is Speed?The speed of an object, sometimes known as "v" in daily speech and kinematics, is a scalar quantity that measures how much its position changes over time or how much it changes per unit of time. The distance traveled by an object during a time interval is equal to the duration of the interval divided by the object's speed, with the instantaneous speed being the upper limit of the average speed as the interval's duration becomes closer to zero. Velocity differs from speed. Distance divided by time is the dimension of speed. The meter per second (m/s) is the SI unit of speed, although the kilometer per hour (km/h) or, in the US and UK, miles per hour, is the most widely used measure in daily life (mph). The knot is a popular choice for air and sea travel.From Home to Lake,
Let the speed of driving be 'x' miles per hour,
Time taken = 2 hours
Speed = Distance/Time
⇒ Distance = Speed x Time = 2x ..................(1)
From Lake to Home,
Distance will be the same (as the same route is taken),
Speed = (x-25) miles per hour
Time = 2 + 2 = 4 hours
So, Distance = Speed x Time = 4(x-25) ....................(2)
On equating (1) and (2),
2x = 4(x-25)
simplifying the above equation, we get
⇒ 2x = 4x - 100
⇒ 4x - 2x = 100
⇒ 2x = 100
⇒ x = 100/2
⇒ x = 50
Therefore, the speed of the vehicle while driving from home to the lake was 50 miles per hour.
