To solve this problem, you have to determine the value of the number 3 in both numbers:
6,300 – the number 3 is in the hundreds place so its value is 300
530 – the number 3 is in the tens place so its value is 30
To answer the question, the value of 3 in 6,300 is 10 times the value of 3 in 530.

A drawer contains 4 red socks, 3 white socks, and 3 blue socks. Without looking, you select a sock at random, replace it, and select a second sock at random. What is the probability that the first sock is blue and the second sock is red?
Answer:
[tex]\texttt{Probability}=\frac{3}{25} [/tex]
Step-by-step explanation:
Probability is the ratio of number of favorable outcome to total number of outcomes.
Total number of socks = 4 + 3 + 3 = 10
Number of blue socks = 3
Number of red sock = 4
[tex]\texttt{Probability of selecting blue sock}=\frac{3}{10} \\ [/tex]
[tex]\texttt{Probability of selecting red sock}=\frac{4}{10} \\ [/tex]
For finding the combined probability we need to multiply both the values
[tex]\texttt{Probability that the first sock is blue and the second sock is red}=\frac{3}{10}\times \frac{4}{10}=\frac{12}{100}=\frac{3}{25} \\ [/tex]
[tex]\texttt{Probability}=\frac{3}{25} [/tex]
Working together, it takes two roofers 10 hours to put a new roof on a portable classroom. if the first roofer can do the job by himself in 12 hours, how many hours will it take the second roofer to do the job by himself?
Number of hours the second roofer to do the job by himself is 60 hours.
Given that, working together, it takes two roofers 10 hours to put a new roof on a portable classroom.
What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
Working together 1/10 roofs per hour
First roofer 1/12 roofs per hour
So, equation is x + 1/12 = 1/10
x = 1/10 - 1/12
= 6/60 - 5/60 = 1/60
Together, they work 1/60 + 1/12
= 1/60 + 5/60
= 6/60 = 1/10
Therefore, number of hours the second roofer to do the job by himself is 60 hours.

Which of the following are independent pairs of events? Check all that apply.
A.Flipping two coins and having one show a head and the other show a head
B.Being sneezed on and catching a cold
C.When rolling a pair of dice, getting a total of 6 and having one die show a 3
D.Rolling a 4 on one die and rolling a 2 on another die
E.Seeing clouds and winning the lottery,
The best answer for these question would be:
A. Flipping two coins and having one show a head and the other show a head
D. Rolling a 4 on one die and rolling a 2 on another die
E. Seeing clouds and winning the lottery
Independent events in math means that the first situation does not affect the other variable. It is generally the individual probability that will happen to the solution. Which means that you have to determine whether the first situation will be affected on the second events that will happen. While the dependent events, have the opposite effect.

Michelle works at a store that sells clothing accessories. The supply function for baseball caps is P=Q-6, where P is the price and Q is the quantity of baseball caps. If Michelle sells the baseball caps for $19 apiece, how many baseball caps will the store make?
A. 31 baseball caps
B. 6 baseball caps
C. 19 baseball caps
D. 25 baseball caps
Answer:
25
Step-by-step explanation:
Given : The supply function for baseball caps is P=Q-6, where P is the price and Q is the quantity of baseball caps.
To Find: If Michelle sells the baseball caps for $19 apiece, how many baseball caps will the store make?
Solution:
The supply function for baseball caps is P=Q-6
where P is the price
Q is the quantity of baseball caps.
Now we are given that Michelle sells the baseball caps for $19 a piece.
So, P = 19
Substitute the value in the function:
19=Q-6
19+6=Q
25 =Q
Thus If Michelle sells the baseball caps for $19 apiece, the store make will make 25 baseball caps .

What is the formula of quadratic equations?
Final answer:
The quadratic formula is used to find the solutions of quadratic equations. It is x = (-b ± √(b² - 4ac)) / (2a). The discriminant determines the nature of the solutions.
Explanation:
The formula for quadratic equations is:
x = (-b ± √(b² - 4ac)) / (2a)
Quadratic equations are equations of the form ax² + bx + c = 0. The quadratic formula is used to find the solutions or roots of these equations. The discriminant, b² - 4ac, determines the nature of the solutions: if it is positive, there are two real solutions; if it is zero, there is one real solution; and if it is negative, there are two complex solutions.

Find two positive consecutive odd integers such that the square of the larger integer is one less than twice the square of the small integer.
Answer:
smaller integer = 5
Larger integer = 7
Step-by-step explanation:
Let the first odd integer be x
Then the next consecutive integer will be x + 2
Now, The square of larger integer is 1 less than twice the square of the smaller integer.
As, x < x + 2
Smaller integer = x
Larger integer = x + 2
⇒ (x + 2)² + 1 = 2·x²
⇒ x² + 4 + 4x + 1 = 2x²
⇒ x² - 4x - 5 = 0
⇒ x² - 5x + x - 5 = 0
⇒ x(x - 5) + 1(x - 5) = 0
⇒ (x - 5)(x + 1) = 0
⇒ x = 5 or x = -1
But we need positive integer so x = -1 is rejected.
Hence, x = 5
So, smaller integer = 5
Larger integer = 7

What is the equation of a vertical line passing through (−5, −2)?
x = −5
y = −2
x = −7
y = −3
Answer:
x = -5
First option is correct.
Step-by-step explanation:
The vertical line is passing through the point (−5, −2).
The equation of a vertical line is in the form x = k
For vertical line, the x-coordinate of each point that lie on the line remains same. Only the y-coordinate is different
For the given point, the x-coordinate = -5
Hence, k = -5
Therefore, the equation of line is x = -5
First option is correct.

The number 12,089 is?
< 12,098.
= 12,098.
> 12,098.
Or none of these is correct
Final answer:
The numbers 12,089 is less than 12,098, as determined by comparing the ones place of each number., hence the correct option is A
Explanation:
The student asks for the correct comparison between the numbers 12,089 and 12,098. To generate an accurate answer, we compare the digits from left to right.
Since the thousands, hundreds, and tens places are the same, we look at the ones place to determine which number is greater. Comparing the ones digits, we see that 9 (in 12,098) is greater than 8 (in 12,089), therefore 12,089 is less than 12,098.
The correct answer is:
12,089 < 12,098.
