$15 is the new price of the item
Dunder Mifflin recently expanded its supply to include not just paper, but also copiers (much to Pam’s delight). The expansion was a smashing success, with the copier production process producing defective parts only 0.8% of the time during the first year. Michael Scott believes that updates to the production technology have improved this process. He randomly selects 1000 parts and finds 6 defective parts. Do these data provide evidence at the 5% level that the process has improved?

Solve the exponential equation
Solve exponential equation 1/16=64^4x-3
Answer:
x = 7/12
Step-by-step explanation:
Solve the exponential problem :
1/16=64^4x-3
1 / 4^2 = 4^3(4x - 3)
4^-2 = 4^3(4x - 3)
-2 = 3(4x - 3)
-2 = 12x - 9
-2 + 9 = 12x
7 = 12x
7/12 = 12x/12
7/12 = x
Hence, x = 7/12
Answer is 7/12, or approx. 0.58333... Answer explained in attached file.

Which of the following statements about a rhombus is not true?
A rhombus is a parallelogram.
A rhombus has two sets of parallel sides.
A rhombus has four sides of equal length.
A rhombus has four right angles.
Given:
Consider a rhombus.
To find:
Which of the given statements about a rhombus is not true?
Solution:
Properties of a Rhombus:
1. It is a quadrilateral which is a special case of a parallelogram.
2. It has four equal sides.
3. It has two sets of parallel sides.
4. Opposite angles are equal.
5. Diagonals are perpendicular bisectors.
Since a rhombus doesn't has four right angles, therefore the last statement in the given options is not true about the rhombus.
Hence, the correct option is D.

Answer:
The answer to question 14 is (6, 5), and the answer to question 15 is D) x = -2 and y = 1.
Step-by-step explanation:
Question 14 explanation: Because each line on the graph represents a different function, that means that the point where they intersect is the answer, as the point both appear on the equations [tex]y = \frac{1}{2} x+2[/tex] and [tex]y=x-1[/tex]. Since the two equations' point of intersection is (6, 5), that means the solution to the system of equations is the point (6, 5).
Question 15 explanation: The solution to the system of equations [tex]3x+4y=-2[/tex] and [tex]2x-4y=-8[/tex] would be the x and y values that satisfy both equations. If you select the pair on selection D, you'll find that it's valid. [tex]3(-2)+4(1)=-2[/tex] ⇒ [tex]-6+4=-2[/tex] ⇒ [tex]-2 = -2[/tex], which is true, so choice D works for the first equation. [tex]2(-2)-4(1)=-8[/tex] ⇒ [tex]-4-4=-8[/tex] ⇒ [tex]-8=-8[/tex], which is also true. This means that x = -2 and y = 1 is the solution to the system of equations, making choice D the correct answer.
Gloria, Teresa, and Rebecca went to an office supply store. Gloria bought 8 pencils, 4 markers, and 6 erasers. Her total was
$22.00. Teresa spent $19.25 buying 5 pencils, 7 markers, and 8 erasers. Rebecca bought 5 pencils, 5 markers, and 4
erasers for $15.75. What is the cost of each item?
Answer:
pencil: $2
marker: $0.75
eraser: $0.5
Step-by-step explanation:
Let the prices of one pencil, one marker, and one eraser be p, m, and e, respectively.
Gloria:
8p + 4m + 6e = 22 Eq. 1
Teresa:
5p + 7m + 8e = 19.25 Eq. 2
Rebecca:
5p + 5m + 4e = 15.75 Eq. 3
Subtract Eq. 3 from Eq. 2:
2m + 4e = 3.5 Eq. 4
Multiply Eq. 2 by 8 and subtract from it Eq. 1 multiplied by 5.
40p + 56m + 64e = 154 Eq. 2 times 8
(-) 40p + 20m + 30e = 110 Eq. 1 times 5
----------------------------------------
36m + 34e = 44
18m + 17e = 22 Eq.5
Now use Equations 4 and 5 as a system of two equations in two variables.
Multiply Eq. 4 by 18. Subtract Eq. 5 from it.
36m + 72e = 63
(-) 36m + 34e = 44
-----------------------------
38e = 19
e = 19/38
e = 0.5
Now substitute e = 0.5 into Eq. 4 to fond m.
2m + 4e = 3.5
2m + 4(0.5) = 3.5
2m + 2 = 3.5
2m = 1.5
m = 0.75
Substitute e = 0.5 and m = 0.75 into Eq. 1 to find p.
8p + 4m + 6e = 22
8p + 4(0.75) + 6(0.5) = 22
8p + 3 + 3 = 22
8p = 16
p = 2
Answer:
pencil: $2
marker: $0.75
eraser: $0.5
The cost of each of the items are: cost of pencil = $2, cost of marker = $ 3 / 4 and cost of eraser = $ 1 / 2
let
the cost of pencil = x
the cost of marker = y
the cost of eraser = z
How to form the equation to calculate cost of each itemGloria bought 8 pencils, 4 markers, and 6 erasers. Therefore,
8x + 4y + 6z = 22
Teresa spent $19.25 buying 5 pencils, 7 markers, and 8 erasers. Therefore,
5x + 7y + 8z = 19.25
Rebecca bought 5 pencils, 5 markers, and 4 erasers for $15.75. Therefore,
5x + 5y + 4z = 15.75
Let'a combine the equation
8x + 4y + 6z = 22
5x + 7y + 8z = 19.25
5x + 5y + 4z = 15.75
Therefore,
x = 2, y = 3 / 4 and z = 1 / 2
Therefore, the cost of each item are as follows;
cost of pencil = $2
cost of marker = $ 3 / 4
cost of eraser = $ 1 / 2

To find new numerator:
a) Multiply the whole number 1 by the denominator 6. Whole number 1 equally 1 * 6/
6
= 6/

b) Add the answer from previous step 6 to the numerator 1. New numerator is 6 + 1 = 7
c) Write a previous answer (new numerator 7) over the denominator 6.
One and one sixth is seven sixths
Conversion a mixed number 7 3/

to a improper fraction: 7 3/6 = 7 3/
6
= 7 · 6 + 3/

To find new numerator:
a) Multiply the whole number 7 by the denominator 6. Whole number 7 equally 7 * 6/

b) Add the answer from previous step 42 to the numerator 3. New numerator is 42 + 3 = 45
c) Write a previous answer (new numerator 45) over the denominator 6.
Seven and three sixths is forty-five sixths
Subtract: 7/

For adding, subtracting, and comparing fractions, it is suitable to adjust both fractions to a common (equal, identical) denominator. The common denominator you can calculate as the least common multiple of both denominators - LCM(6, 6) = 6. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 6 × 6 = 36. In the next intermediate step, the fraction result cannot be further simplified by canceling.
In words - seven sixths minus forty-five sixths = minus nineteen thirds.

From the 64 values in the table on the left, count how many fall within the given ranges under the "classes" column in the table on the right. The "frequency" is the number of values in the data that belong to a given "class".
For example, "< -16.0" means "values below -16.0". Only one number satisfies this: -16.2 (first row, third column). So the frequency for this class is just 1.
Then for the range "-15.9 - 13.0", which probably means "numbers between 15.9 and -13.0, inclusive", the frequency is 0 because every number in the table is larger than the ones in this range.
And so on.

Answer:
m = -1
Step-by-step explanation:
3m + 4 = 1
subtract 4 from each side of the equation:
3m + 4 - 4 = 1 - 4
3m = -3
divide both sides by 3:
3m/3 = -3/3

James is saving up to buy himself a new drum set that costs $1300. He has already saved $500 and his parents have agreed to pay for half of the total cost. He wants to save the rest of the money he needs over six months. If he saves the same amount each month, how much does he have to save each month? Round your answer to the nearest penny
Answer:
25$ Each month
Step-by-step explanation:
Half of 1300$ is 650$ so add the 500$ and then subtract is from 1300$ you get 150$ needed, so across 6 months he needs to raise 25$
