The simplified exponential notation of the given expression is 9a²b
What is an exponential expression?
An expression in the form of a² is called exponential expression.
The simplified exponential notation of the given expression is 18 * a³ b² / 2ab
The given expression is: 18a³b² / 2ab
We can write the above expression as:
(18/2 ) (a³ / a ) (b² / b )
We know that
aˣ / aⁿ= aˣ⁻ⁿ
a³ / a = a³⁻¹ = a²
b² / b = b²⁻¹= b
So, ( 18/2) ( a³/a) (b²/ b) = 9 a²b
Hence, The simplified exponential notation of the given expression is 9a²b

The equation 1 – 4∕3x = 1∕2(–x + 7) has what type of solution set?
Question 14 options:
A)
One solution
B)
Infinitely many solutions
C)
Two solutions
D)
No solutions
The linear equation:
1 - (4/3)x = (1/2)*(-x + 7)
Has one solution.
Which type of solution set the equation has?So here we have a linear equation:
1 - (4/3)x = (1/2)*(-x + 7)
To solve it, let's isolate the variable x.
1 - (4/3)*x = -(1/2)*x + (1/2)*7
-(4/3)*x + (1/2)*x = 3.5 - 1
-(8/6)*x + (3/6)*x = 2.5
(-5/6)*x = 2.5
x = (-6/5)*2.5
x = 3
So the linear equation has a single solution, thus, the correct option is A.

Exercise 1: Your friends are organizing a trip for the upcoming spring break. They are
undecided between visiting a national park or visiting a city in the USA. The probability your
friends decide to visit a national park is .35. If your friends decide to visit a national park, the
probability you will join them is .75. On the other hand, if your friends decide to visit a city in
the USA, the probability you will join them is .40.
a) What is the probability you will join them? (Hint: the appropriate visualization
tool might be helpful).
b) If you end up joining them, what is the probability your friends have decided to
visit a national park?
A) The probability that you will join them is 0.523;
B) If you end up joining them, the probability your friends have decided to visit a national park is 0.50.
What is probability?Note that probability is an area of mathematics that deals with numerical representations of how probable an event is to occur or how likely a statement is to be true. The probability of an occurrence is a number between 0 and 1, where 0 denotes the event's impossibility and 1 represents certainty.
In the above case, Note that to determine the probability that you will join them, we need to use the formula for conditional probability, which is:
P(A and B) = P(A|B) * P(B)
In this case, A is the event that you join them, and B is the event of your friends deciding to visit either a national park or a city in the USA.
Given the above, we have:
P(join and national park) = P(join|national park) * P(national park) = 0.75 * 0.35
P(join and city) = P(join|city) * P(city) = 0.40 * 0.65
Thus to obtain the probability that you will join them: we must add the two probabilities: P(join and national park) and P(join and city)
⇒ P(join) = P(join and national park) + P(join and city)
= 0.75 * 0.35 + 0.40 * 0.65
= 0.523
Thus, it is correct to state that the probability or likelihood that you join them is: 0.523
B) If you decide to join them, the probability that your friends have decided to go to a national park is determined using the Bayes Theorem. This theorem is given as:
P(B|A) = P(A|B) * P(B) / P(A)
Where A is the event of you going with them, and B is the event of your friends deciding to go to a national park.
P(national park|join) = P(join|national park) * P(national park) / P(join)
= 0.75 * 0.35 / 0.525
= 0.5019120459
[tex]\approx[/tex] 0.50
Thus, it is correct to state that the probability your friends have decided to visit a national park is 0.57 if you eventually join them.

For the given number line plot the inequality obtained is { -∞ < x < -2 and 5 < x < ∞}.
What is an inequality?
In Algebra, an inequality is a mathematical statement that uses the inequality symbol to illustrate the relationship between two expressions. An inequality symbol has non-equal expressions on both sides. It indicates that the phrase on the left should be bigger or smaller than the expression on the right, or vice versa.
To represent inequalities on a number line show the range of numbers by drawing a straight line and indicating the end points with either an open circle or a closed circle.
An open circle shows it does not include the value.
A closed circle shows it does include the value.
Let the unknown value be x.
The first range is starting form -2 and moving towards -∞.
Since the circle is open it will not include the value.
So the inequality is -∞ < x < -2.
The second range is starting form 5 and moving towards ∞.
Since the circle is open it will not include the value.
So the inequality is 5 < x < ∞.
Therefore, the inequality is { -∞ < x < -2 and 5 < x < ∞}.

Find the slope of the line
Answer:
m = 20
Step-by-step explanation:
Slope = rise/run or (y2 - y1) / (x2 - x1)
Let's pick 2 points (0,5) ( 1 , 25)
The y increase by 20, and the x increase by 1, so the slope is
m = 20
Answer:
The slope is 20.
Step-by-step explanation:
To find the slope of the line, we pick two points on the line and use the slope formula.
m = ( y2-y1)/(x2-x1)
The points I used were ( 0,5) and ( 1,25).
m = ( 25-5)/( 1-0)
= 20/1
= 20
The slope is 20.

A metallurgist has one alloy containing 35% titanium and another containing 69% titanium. How many pounds of each alloy must he use to make 53 pounds of a third alloy containing 40% titanium?
Answer:
Let x be the amount of alloy 1 used, and y be the amount of alloy 2 used.
We know that:
x + y = 53 (total weight of alloy 3 is 53 pounds)
0.35x + 0.69y = 0.40(53) (40% of the alloy 3 is titanium)
We can use the first equation to solve for one of the variables in terms of the other:
y = 53 - x
Substitute this expression into the second equation:
0.35x + 0.69(53-x) = 0.40(53)
0.35x + 36.97 - 0.69x = 21.2
-0.34x = -15.77
x = 46.44 pounds of alloy 1.
y = 53 - x = 6.56 pounds of alloy 2.

In a sample of size 100, the median splits the data into two equal parts of 50 observations each. So, 50 observations are below the median and 50 observations are above the median.
The first quartile (Q1) separates the lowest 25% of the data from the rest, so 50 observations are between the median and Q1.
The interquartile range (IQR) is defined as the difference between the third quartile (Q3) and Q1, and represents the range of the middle 50% of the data. Since the IQR contains both Q1 and the median, it encompasses all observations between Q1 and the median,
or a total of 75 observations.

The cost p of making n articles is given by p=x+yn where x and y are constants. The cost of making 7 articles is 29 and the cost of making 5 articles is 21.solve the equations to find the values of x and y
Answer: The values of x and y are x = 16 and y = 4
Step-by-step explanation:
We can use the information given to set up two equations, as follows:
p = x + 7y = 29 (the cost of making 7 articles)
p = x + 5y = 21 (the cost of making 5 articles)
We can then solve for x and y using either substitution or elimination method.
Substitution method:
Solving the first equation for x:
x = 29 - 7y
Then substitute this value of x into the second equation:
29 - 7y = 21 + 5y
Solving for y:
y = 4
Now we can substitute this value of y back into the first equation:
x = 29 - 7(4) = 5
So the values of x and y are x = 5 and y = 4
elimination method:
Subtracting the second equation from the first:
x = 8 + 2y
Now we can substitute this equation into the first equation:
29 = 8 + 2y + 7y
Solving for y:
y = 4
Now substitute this value of y back into the first equation:
x = 8 + 2(4) = 16
So the values of x and y are x = 16 and y = 4.
Note that both methods give the same solution, but the values of x are different because the two equations are not independent and therefore not the same.
