Given the following question
7 notepads cost $4.55 what's the unit price?
Unit price is price per unit, we find the price per unit by dividing the total cost of the notepads by the total amount of the notepads which is 7.
[tex]unitp=cost\div quantity[/tex]
[tex]7n=4.55[/tex]
[tex]4.55\div7=0.65[/tex]
[tex]=0.65[/tex]
The unit price of the seven notepads is "$0.65."

Write the polynomial in factored form. Show all the steps that you use to solve this problem.
x^3 - 3x^2 - 10x
Answer:
x( x - 5)( x + 2)
Step-by-step explanation:
The polynomial is x^3 - 3x^2 -10x. Since each term has at least one x, we can factor out an x.
This gives us x( x^2 - 3x - 10).
Now, we may factor the second degree polynomial.
_ × _ = -10? (or a × c, where ax^2 + bx + c?)
_ + _ = -3? (or b?)
Well, -5 times 2 equals 10, and -5 plus 2 equals -3.
We use these values to factor further.
So, our final answer becomes x( x - 5 )( x + 2 ).
You can check this by simply multiplying and distributing the terms!
I hope this helped! :)

Answer:
d) m∠a = m∠f
Step-by-step explanation:
Where a transversal crosses parallel lines, certain relationships between the angles are established. Effectively, the two same-side interior angles are supplementary, as they would be in a parallelogram. Here, those are angles B and F, or angles A and E.
The vertical- and linear-angle relationships give rise to all of the other ways this is expressed. For example, angles A and B are a linear pair, so supplementary. Since B and F are supplementary, and B and A are supplementary, F = A. Using more formal language, ...
m∠a = m∠f

Answer: 161 m^2
Step-by-step explanation:
The surface area composes of 4 triangles and 1 square.
The side length of the square is 7 m, so the area is 49 m^2 because the area of a square is the side length^2.
Each of the triangles has a base of length 7 m and a height of 8 m, so the area of each triangle is 7m*8m/2 = 28 m^2 because the area of a triangle is the base*height/2.
Since there are 4 triangles, the total surface area of the 4 triangles is 28 m^2 * 4 = 112 m^2.
Adding that to the area of the square, we get 49 m^2 + 112 m^2 = 161 m^2
In an accelerated failure test, components are operated under extreme conditions so that a substantial number will fail in a rather short time. In such a test involving two types of microchips, 620 chips manufactured by an existing process were tested, and 125 of them failed. Then, 820 chips manufactured by a new process were tested, and 130 of them failed. Find a 90% confidence interval for the difference between the proportions of failures for chips manufactured by the two processes. (Round the final answers to four decimal places.) The 90% confidence interval is ( . , ).
Answer:
The 90% confidence interval is [tex] 0.0097 < p_1 -p_2 < 0.0773 [/tex]
Step-by-step explanation:
From the question we are told that
The first sample size is [tex]n_1 = 620[/tex]
The number of chips that failed is k = 125
The second sample size is [tex]n_2 = 820[/tex]
The number of chips that fail is [tex]u = 130[/tex]
Generally the confidence level is 90% , hence the level of significance is
[tex]\alpha = (100 - 90)\% [/tex]
=> [tex]\alpha = 0.10 [/tex]
Generally from the normal distribution table the critical value of [tex]\frac{\alpha }{2}[/tex] is
[tex]Z_{\frac{\alpha }{2} } = 1.645[/tex]
Generally the first sample proportion is
[tex]\r p _1 = \frac{125}{620}[/tex]
=> [tex]\r p _1 = 0.202[/tex]
Generally the second sample proportion is
[tex]\r p _1 = \frac{130}{820}[/tex]
=> [tex]\r p _1 = 0.1585[/tex]
Generally the standard error is mathematically represented as
[tex]SE = \sqrt{\frac{\r p_1 (1 - \r p_1)}{n_1} +\frac{\r p_2 (1 - \r p_2)}{n_2} }[/tex]
=> [tex]SE = \sqrt{\frac{0.202(1 - 0.202)}{620} +\frac{0.1585 (1 - 0.1585)}{820} }[/tex]
=> [tex]SE = 0.0206[/tex]
Generally the margin of error is mathematically represented as
[tex]E = Z_{\frac{\alpha }{2} } * SE[/tex]
=> [tex]E = 1.645 * 0.0206[/tex]
=> [tex]E =0.0338[/tex]
Generally 95% confidence interval is mathematically represented as
[tex](\r p_1 -\r p_2) -E < p_1 - p_2 < (\r p_1 -\r p_2) +E [/tex]
=> [tex](0.202 -0.1585) -0.0338 < p_1 - p_2 < (0.202 -0.1585) +0.0338 [/tex]
=> [tex] 0.0097 < p_1 - p_2 < 0.0773 [/tex]
What is the value of x?

6
Answer:
x = 6
Step-by-step explanation:
Using the relationships between the entries in the table, you can find x two different ways.
1.The numbers down the Total column add to give the one at the bottom:
0.1 + 0.09x = 0.64
0.09x = 0.54 . . . . . . . subtract 0.1
x = 6 . . . . . . . . . . . . divide by 0.9
__
2.The product of the numbers in the first two columns is the number in the third. On the bottom row, this means ...
(2 +x)(0.08) = 0.64
2 +x = 8 . . . . . . . . . . . divide by 0.08
x = 6 . . . . . . . . . . . subtract 2

7b+2 b = 2
3(2c-10)
1+2.1y-0.9y+4
Answer:
If you were to solve for, 7b+ 2b = 2 then;
7b+ 2b = 2
Combine like terms first:
(7b + 2b)
9b = 2
Then divide by 9 from both sides to solve for b:
/9 /9
b = 2/9 or 0.222..
If you were to solve for, 3(2c - 10) then;
3(2c - 10)
Use the distributive property, and multiply 3 to both 2c and 10:
3(2c) - 3(10)
6c - 30
If you were to solve for, 1 + 2.1y - 0.9y + 4 then;
1 + 2.1y - 0.9y + 4
Combine like terms:
(1 + 4) (2.1y - 0.9y)

Angle 1 and Angle 2 are complimentary angles. Find x and the measure of Angle 1.
Angle 1 = (3x+2)°
Angle 2 = (4x +4)º
x = ?
The measure of Angle 1 = ?
degrees
Answer:
x=12 pls give brainliest
Step-by-step explanation:
Answer: x = 12, Angle 1 = 38°
Step-by-step explanation: Complimentary angles add up to 90°.
Add the two angles and set them equal to 90°:
(3x + 2) + (4x + 4) = 90
Add like terms:
7x + 6 = 90
Subtract 6 from both sides:
7x = 84
Divide both sides by 7:
x = 12
Now, to get Angle 1, plug x in:
Angle 1 = 3(12) + 2
Angle 1 = 38°

3 Consider two vectors Az 31 - 2; and Bz-i-4;. alculated B C) A+B and A-B B G) / Atb 1 and (A-Blu | - B (i fra) Direction of (A+B) and|A-b] B) B + ดู B BJ
Step-by-step explanation:
1. A+B=Just add the J hat with J hat and add the I hat with the I hat.
[tex](3i + ( - 1)i + ( - 2) + ( - 4)j = 2i - 6j[/tex]
A-B=
[tex]3 - ( - 1)i + ( - 2) - ( - 4)j = 4i + 4j[/tex]
2. Take the magnitude of A+B
[tex]2 {}^{2} + ( - 6) {}^{2} = {r}^{2} [/tex]
[tex]40 = {r}^{2} [/tex]
[tex]r = \sqrt{40} [/tex]
So the magnitude is root of 40.
So the magnitude of A+B is
The magnitude of A-B
[tex] {4}^{2} + {4}^{2} = 4 \sqrt{2} [/tex]
So the magnitude is
[tex]4 \sqrt{2} [/tex]
c. To find direction, we need to find the angle.
Use this rule,
[tex] \tan(x) = \frac{bj}{bi} [/tex]
For A+B, we get
[tex] \tan(x )= \frac{ - 6}{2} [/tex]
[tex] \tan(x) = - 3[/tex]
Since this is a southeast, the degree is 288.43.
The direction is southeast, 288.43 degrees
For A-B, we get
[tex] \tan(x) = \frac{4}{4} [/tex]
[tex] \tan(x) = 1[/tex]
Since this is northeast, the degree is 45 degrees.
The direction is northeast, 45 degrees.

Answer: Y= 2/3x + 9
Explanation: The equation is in slope-intercept form, y=mx+b. Since it is parallel to the equation, it has the same slope (2/3x) and since b is the x intercept, b is 9.

What is a Linear Equation of a line?
A linear equation is an algebraic equation of the form y=m x + b. involving only a constant and a first-order (linear) term, where m is the slope and b is the y-intercept
Parallel lines have the same slope.
Given data ,
The x-intercept is obtained when we set the value y = 0
As the x-intercept is 9 , therefore the point representing the x-intercept will be: ( 9 , 0 )
Now , the equation of line is given by y = m x + c
And , y = ( 2 / 3 ) x - 10
Since the lines are parallel , they will have same slope
So , the equation in slope intercept for the line will be
y = ( 2 / 3 ) x + 9
Hence the equation of line will be y = ( 2 / 3 ) x + 9
