=3/2
Step-by-step explanation:
Answer:
x = -1/2
x = 3/2
Step-by-step explanation:
4x² - 4x = 3
Subtract 3.
4x² - 4x - 3 = 0
Factor by grouping.
(2x + 1)(2x - 3) = 0
2x + 1 = 0
2x - 3 = 0
x = -1/2
x = 3/2
good luck, i hope this helps :)

For 50 consecutive days, a process engineer has measured the weight of a component after it has been coated with special paint. Each day, she takes a sample of 10 components. The average across all 500 components is 45.343019 grams. The average range across all parts is 0.0076382 grams. When constructing an X-bar chart, what would be the centerline, and what would be the upper and lower control limits
Answer:
UCL (X-bar) = X mean+ (A2 x R-bar)
LCL (X-bar) = X mean -(A2 x R-bar)
Center line = Mean
A2 for sample size of 10 = 0.308
X mean = 45.343019
R bar = Average of range = 0.0076382
UCL (X-bar) =45.343019+(0.308*0.0076382) = 45.3453715656 grams
LCL (X-bar) = 45.343019-(0.308*0.0076382) = 45.3406664344 grams
Center line = Mean = 45.343019

Step-by-step explanation:
given
6n - 10
Take 2 as common then
2 ( 3n - 5 )
hope it helps :)
Answer:
2(3n-5)
Step-by-step explanation:
You need to find the highest common factor (2 in this case).
When the word factorise is mentioned that means there has to be brackets in your answer.
After the highest common factor is found then divide the numbers by it. for example, 6÷2 and -10÷2.

Find the diameter of the circle with a circumference of 80 feet. Use 3.14 for pi. Round your answer to the nearest tenth.
12.7 ft
25.5 ft
40.0 ft
50.9 ft
Answer:
Option B = 25.5 ft
Step-by-step explanation:
Circumference = 80 ft
C = 2πr
80 = 2 * (22/7) * r
80 = (44/ 7) * r
So, Radius (r) = 80 * (7/44)
= 12.72 Feet
--> Diameter = 2r = 2 * 12.72
= 25.45 Feet
Therefore, Answer = Option B = 25.5 Feet (Round off)

Solve for the system of equations using elimination
Answer:
(-1,5)
Step-by-step explanation:
Solve the following system:
2 y + x = 9 | (equation 1)
2 y + 3 x = 7 | (equation 2)
Subtract equation 2 from equation 1:
( 2 y + x ) - ( 2 y + 3 x ) = 9 - 7
- 2 x = 2
x = - 1
Substitute into question 1:
2 y - 1 = 9
y = 5
Answer: x = -1 , y = 5

In the first year of a 10,000 investment the interest rate was 6%. All earned interest remained invested for the second year, and the interest rate increased to 7%. What was the percent increase of the entire investment after two years?
Answer:
13.4%
Step-by-step explanation:
First year:
$10,000*6% = $600
New balance = $10,600
Second Year:
$10,600*7% = $742
$10,600+ $742 = $11,342
Total Return:
Final Balance - Initial balance
$11,342 - $10,000 = $1,342
$10,000*x ÷ $1,342
x = $1,342/$10,000
x = 0.1342
0.134 = 13.4%

Answer:
A = 1280 in²
Step-by-step explanation:
We know that the volume of a cube is A = a³, where a is the length of one of the edges.
So, to find a:
a³ = 4096
a = ∛4096
a = 16 in
Now, we need to find the surface area of the square on the cube, where:
A = 6a², because we are making a box (that is empty inside).
However, we need to change the formula to:
A = 5a², because the problem says that there is no top (so there are only 5 squares)
A = 5(16)²
A = 1280 in²

For the given triangle the statement that is true for length x is -
x < 9
What are triangles?
Triangles are a particular sort of polygon in geometry that have three sides and three vertices. Three straight sides make up the two-dimensional figure shown here. An example of a 3-sided polygon is a triangle. The total of a triangle's three angles equals 180 degrees. One plane completely encloses the triangle.
The length of 1 side is = 5 units
The length of second side is = 4 units
A key geometrical concept that connects the lengths of a triangle's sides is the triangle inequality theorem.
It stipulates that the length of the remaining side must be greater than the sum of the lengths of any two sides of a triangle.
The triangle inequality theorem can be written out as follows if a, b, and c are the lengths of a triangle's sides:
b + c > a
a + c > b
b + a > c
Since the sum for the given triangle is 5 + 4 = 9
So, the third side must be less than 9.
Therefore, the inequality is x < 9.
