explain ehy the square root of 64 has a positive and a negative value.
you have scored 7,10,8 , and 9 on four quizzes . write and solve an equation to find the score you need on the fifth quiz so that your mean score is 8
To achieve a mean score of 8 after five quizzes, you would need to score 6 in your fifth quiz, assuming your scores in the first four quizzes were 7, 10, 8, and 9 respectively.
Explanation:Yes, these scores are associated with the subject of mathematics, particularly the branch of math known as statistics. This involves determining how to achieve a desired mean, which in this case is 8, given your previous quiz scores.
The mean score is determined by adding all your quiz scores together and dividing by the total number of quizzes. So for your first four quizzes, the total is 7 + 10 + 8 + 9 = 34. The mean so far is 34 ÷ 4 = 8.5 which is already above our targeted mean of 8.
To achieve a mean of 8 over 5 quizzes, the total of your scores would need to be 8 x 5 = 40. Therefore, the score you would need to get on your fifth quiz would be 40 (the desired total) - 34 (the current total) = 6.

3. A∩(B∪C)=A∩(B∪C)=
4. A^c ∪ B^c∪ C^c=
5. (C−A)∪(B−C)=(C−A)∪(B−C)=
Final answer:
The question involves calculating various set operations in interval notation, including the union, intersection, and complements using intervals A, B, and set C (negative real numbers) within the universal set of real numbers R.
Explanation:
The student is working with set operations in interval notation, particularly focusing on the union, intersection, and complement relative to the set of real numbers R. Given intervals A=[-7,1], B=(-1,5), and set C being the negative real numbers, we need to perform various set operations.
A⋃B is the union of A and B, which is the set of all elements in either A or B.A∩B∩C is the intersection of A, B, and C, which represents all elements common to all three sets.A∩(B⋃C) represents the intersection of A with the union of B and C.A¹ ⋃ B¹ ⋃ C¹ is the union of the complements of A, B, and C relative to the universal set R.(C-A)⋃(B-C) represents the union of the set difference of C and A with the set difference of B and C.how can you quickly calculate 20 percent of any bill amount?
Answer:
There are many ways to do this calculation. Few are listed below.
1. Whenever we say percent, that means divided by hundred. And any number divided by 100 will result in putting a decimal to two places left. Like 20% will becomes [tex]\frac{20}{100}[/tex] = 0.20
And you can multiply the bill amount with 0.20 mentally.
2. You can also simply divide the total bill amount by 5, it will be equal to 20% of the total bill amount. Like if bill amount is $200.
[tex]\frac{200}{5}=40[/tex] and [tex]0.20\times200=40[/tex]. Both values are same.

Amy has set aside $150 a month for her cell phone bill. The cost for a monthly cell phone plan is a $65 access fee plus $20 per gigabyte of data used. Which expression represents the amount of money Amy has left from her monthly budget after she pays her cell phone bill?
The expression to represent the amount of money Amy has left from her monthly budget after paying her cell phone bill is $85 - $20x.
Explanation:To find the amount of money Amy has left from her monthly budget after paying her cell phone bill, we need to subtract the cell phone bill from her monthly budget. Amy has $150 a month and the cell phone bill consists of a $65 access fee plus $20 per gigabyte of data used.
Let's represent the amount of data used in gigabytes as 'x'. So, the expression to represent the amount of money Amy has left is:
$150 - ($65 + $20x)
This expression simplifies to:
$85 - $20x
So, the amount of money Amy has left from her monthly budget after paying her cell phone bill is $85 - $20x.
The expression that represents the amount of money Amy has left from her monthly budget after she pays her cell phone bill is $150 - ($65 + $20x).
Explanation:Amy has set aside $150 a month for her cell phone bill. The cost for a monthly cell phone plan is a $65 access fee plus $20 per gigabyte of data used. To calculate the amount of money Amy has left from her monthly budget after she pays her cell phone bill, we need to subtract the total cost of the cell phone plan from her budget. So, the expression that represents the amount of money Amy has left is:

Although she's only in middle school, Tameka loves to drive go-carts! Her favorite place to drive go-carts, Drivers Delight, has 3 circular tracks. Track 1 has a radius of 60 feet. Track 2 has a radius of 85 feet. Track 3 has a radius of 110 feet.
a. Compute the circumference of Track 1.
b. Compute the circumference of Track 2.
Answer:
Circumference of Track 1 is 377.14 feet and circumference of Track 2 is 534.29 feet.
Step-by-step explanation:
Consider the provided information.
Drivers Delight, has 3 circular tracks. Track 1 has a radius of 60 feet. Track 2 has a radius of 85 feet. Track 3 has a radius of 110 feet.
Part (A)
Compute the circumference of Track 1.
Track 1 has a radius of 60 feet.
The formula used to find the circumference of the circle is: [tex]2\pi r[/tex]
The circumference of Track 1 is:
[tex]2\pi r=2\times \frac{22}{7}\times 60[/tex]
[tex]2\pi r=377.14 [/tex]
Thus, circumference of Track 1 is 377.14 feet.
Part (B)
Compute the circumference of Track 2.
Track 2 has a radius of 85 feet.
The circumference of Track 2 is:
[tex]2\pi r=2\times \frac{22}{7}\times 85[/tex]
[tex]2\pi r=534.29 [/tex]
Thus, circumference of Track 2 is 534.29 feet.

A mother wants to invest $11,000.00 for her son's future education. She invests a portion of the money in a bank certificate of deposit (CD account) which earns 4% and the remainder in a savings bond that earns 7%. If the total interest earned after one year is $ 660.00, how much money was invested in the CD account?
The mother invested $5000 in the CD account and the remaining $6000 in a savings bond. This solution was arrived at by setting up a system of two equations, which we solved simultaneously.
Explanation:Let's denote the amount of money invested in the CD account as x and the amount in the savings bond as y. The total amount of money is $11000, so we can set up the first equation as: x + y = 11000.
Then, the mother earns interest from both accounts. The CD account earns 4%, that's 0.04x while the savings bond earns 7%, that's 0.07y. The total interest is stated to be $660, so we can have the second equation as: 0.04x + 0.07y = 660.
From the first equation, we can solve for y: y = 11000 - x and substitute it into the second equation which gives us: 0.04x + 0.07(11000 - x) = 660.
Solving for x, you should get approximately $5000. This means a balance of $6000 was invested in the bond (11000 - 5000). Therefore, the mother invested $5000 in the CD account.

the formula for the perimeter of a rectangle is P=2l, + 2w, where l is the length and w is the width. A rectangle has a perimeter of 24 inches. Find it's dimensions if it's length is 3 inches greater than it's width.
The dimensions of the rectangle are 7.5 inches and 4.5 inches, or w = 4.5 inches and l = 7.5 inches if the perimeter of a rectangle is P=2l, + 2w.
What is the area of the rectangle?It is defined as the area occupied by the rectangle in two-dimensional planner geometry.
The area of a rectangle can be calculated using the following formula:
Rectangle area = length x width
The rectangle can be defined as the two-dimensional geometry in which the angle between the adjacent sides is 90 degrees. It is a type of quadrilateral.
P = 24 inches
l = 3 + w
P = 2l + 2w
24 = 2(3 + w) + 2w
24 = 6 + 2w + 2w
24 = 6 + 4w
24 - 6 = 4w
18 = 4w
w = 4.5 inches
l = 3 + 4.5 = 7.5 inches
Thus, the dimensions of the rectangle are 7.5 inches and 4.5 inches, or w = 4.5 inches and l = 7.5 inches if the perimeter of a rectangle is P=2l, + 2w.
