Solving this problem is pretty straight forward.
We simply use the formula:
z-score = (x – u) / s
where,
x = sample value = 48 minutes
u = mean value = 30 minutes
s = standard deviation = 7 minutes
Therefore,
z-score = (48 minutes – 30 minutes) / 7 minutes
z-score = 2.57
Final answer:
To calculate Nolan's z-score for playing time against Fairview, use the given formula. Nolan's z-score for this game is 2.57.
Explanation:
A: To calculate the z-score for Nolan's playing time against Fairview, use the formula: z = (x - μ) / σ, where x is Nolan's playing time, μ is the average time, and σ is the standard deviation.
B: Substituting the values, z = (48 - 30) / 7 = 2.57. Therefore, Nolan's z-score for playing time against Fairview is 2.57.

Marty has 2 4/5 quarts of juice. He pours the same amount of juice into 2 bottles how much does he pour into each bottle ?
To know how much Marty pours into each bottle, divide the total juice amount by the number of bottles. His total of 2 4/5 quarts became 14/5 when turned into fifths for easier calculation. Dividing 14/5 by 2, we find that Marty pours 1 2/5 quarts into each bottle.
Explanation:Marty has 2 4/5 quarts of juice. He is trying to equally distribute this juice into 2 bottles. To find out how much juice each bottle will contain, we divide the total amount of juice by the number of bottles.
Given that 1 full quart is made up of 5 fifths, 2 quarts are equivalent to 2x5=10 fifths. Marty has 2 full quarts and 4/5 of a quart, which amounts to 10+4=14 fifths of a quart. So, Marty has 14/5 quarts of juice in total.
If he pours the same amount into 2 bottles, then each bottle will contain half of the total amount. To find this out, we divide the total amount by 2, which gives us 14/5 ÷ 2 = 7/5 quarts. Therefore, Marty pours 7/5 quarts or 1 2/5 quarts of juice into each bottle.

The selling price for a classic car is $14000, which is $2500 less than three times its original price. What was the original price of the car?
The original price of the car was $5,500, which is derived from the mathematical equation based on the given information in the question.
Explanation:The subject of this question is algebra, a branch of mathematics. The question gives us the selling price of a classic car and tells us that this price is $2500 less than three times its original price. We're asked to find the original price. Let’s denote the original price by x.
According to the problem, 3x (three times the original price) minus $2500 equals the selling price ($14,000). So, if we set this up as an equation, it looks like this: 3x - $2500 = $14,000.
To solve for x (the original price), we first need to add $2500 to both sides of our equation, giving us 3x = $16,500. Then, we divide each side by 3 to solve for x, arriving at x = $16,500 ÷ 3 = $5,500. Therefore, the original price of the car was $5,500.

Answer:
[tex]18a - 13.5[/tex]
Step-by-step explanation:
Jason's age is [tex]\frac{1}{2}[/tex] of his brother's age.
Brother age is [tex]12a-9[/tex]
Sum of their ages = Age of Jonson + age of his brother
Jonson's age = half of his brother age
[tex]Jonson's \ age=\frac{12a-9}{2}[/tex]
Sum of their ages =[tex]\frac{12a-9}{2}+12a-9[/tex]
Take common denominator 2

ms.nenadal write 2×7=7×2 on the board. do you agree or disagree? draw arrays to help explain your thinking
It's accurate to say that 2×7 is not equal to 7×2, and the arrays provide a clear visual explanation of this mathematical concept.
Ms. Nenadal wrote 2×7 on the board, which is not equivalent to 7×2. The order of multiplication, as represented by the commutative property, states that changing the order of the factors does not change the product. In this case, 2×7 means adding 2 seven times, while7×2 means adding 7 two times.
Let's draw arrays to illustrate the difference:
For 2×7:
If we represent this as an array, it would have 2 rows and 7 columns, indicating 2 groups of 7.
Array for 2 × 7:
| * * * * * * * |
| * * * * * * * |
For 7×2:
On the other hand, 7×2 would be represented by an array with 7 rows and 2 columns, indicating 7 groups of 2.
Array for 7 × 2:
| * * |
| * * |
| * * |
| * * |
| * * |
| * * |
| * * |
While the product is the same (14) for both, the grouping and arrangement differ. Therefore, it's accurate to say that 2×7 is not equal to 7×2, and the arrays provide a clear visual explanation of this mathematical concept.

One third of the candidates for a job were 25 years old or younger. Two sevenths of the candidates were at least 50 years old. If 84 people applied for the job, how many were between 25 and 50?
1/3 * 84 = 28 were under 25
2/7 * 84 = 24 were at least 50
28 + 24 = 52
84-52 = 32 were between 25 and 50
Answer:
32 candidates are between 25 and 50.
Step-by-step explanation:
84 people applied for the job. [tex]\frac{1}{3}[/tex] of the candidates for a job were 25 years old or younger.
[tex]\frac{1}{3}[/tex] of 84 candidates = [tex]\frac{1}{3}[/tex] × 84 = 28 candidates
[tex]\frac{2}{7}[/tex] of the candidates were at least 50 years old.
[tex]\frac{2}{7}[/tex] of 84 candidates = [tex]\frac{2}{7}[/tex] × 84 = 24 candidates
age 25 and below + age 50 above = 28 + 24 = 52 candidates
Candidates between 25 and 50 = 84 - 52 = 32 candidates
32 candidates are between 25 and 50.
Solve the following system of equations.
4x + 5y = -2
4x + 3y = 10
x=?
y=?
The solution to the system of equations 4x + 5y = -2 and 4x + 3y = 10 is x = 7 and y = -6. This is done by using the elimination method.
Explanation:To solve this system of equations, you can use a method called elimination. The idea is to subtract the second equation from the first to eliminate one of the variables, allowing us to solve for the other.
Subtracting the second equation from the first gives you:
4x + 5y - (4x + 3y) = -2 - 10
This simplifies to: 2y = -12
So, y = -12 / 2 = -6
Then, substitute y = -6 into the first equation:
4x + 5(-6) = -2
This simplifies to 4x - 30 = -2, or 4x = 28
So, x = 28 / 4 = 7
So the solution to the system of equations is x =7, y = -6
