2.find ab
3.find bc
I will give brainlist
Answers
Answer:
x = 5, AB = 27, BC = 19
Step-by-step explanation:
From the diagram
AB + BC = AC , substitute values
4x + 7 + 3x + 4 = 46 , that is
7x + 11 = 46 ( subtract 11 from both sides )
7x = 35 ( divide both sides by 7 )
x = 5
Thus
AB = 4x + 7 = 4(5) + 7 = 20 + 7 = 27
BC = 3x + 4 = 3(5) + 4 = 15 + 4 = 19
Answer:
1. x = 5
2. AB= 27
3. BC = 19
Step-by-step explanation:
Solving for X:
The entire segment is 46. Parts AB and BC make up the whole thing. So, to find x, add both expressions and set them equal to 46.
4x+7+3x+4=46 (combine like terms)
7x+11=46 (subtract 11 from both sides)
7x = 35 (divide by 7)
x = 5
Finding AB:
Plug 5 in for x and evaluate the expression.
4(5)+7
20 + 7= 20
AB is 27
Finding BC:
Plug in 5 for x and evaluate the expression.
3(5)+4
15+ 4=19
Check your work.
Add the values of AB and BC to make sure they add up to 46, which is AC.
27 + 19 = 46, so this is correct.

According to the Triangle Inequality Theorem, if every combination of 2 sides is equal to the third remaining side, then it is a triangle.
3 + 7 > 8
8 + 3 > 7
8 + 7 > 3
Since all of these are true, that means overall, these 3 sides make a triangle.

Defects in computer hard-drives will usually render the entire computer worthless. For a particular model, the percent defective in the past has been 1%. If a sample size of 400 is taken, what would the 95.5% lower control chart limit be?
Answers
Answer:
0.00005
Step-by-step explanation:
We have the average fraction defective as p = 1%
= 0.01
N = 100
Then 95.5% deviation = 2σ
From there we have,
σ = √p*(1-p)/n
When we input these values, into the formula, we will have
σ = √0.01(1-0.01)/100
= √0.01(0.99)/100
= √0.000099
= 0.00995
The LCL = p - 2σ
= 0.01 - 0.00995
= 0.00005
lower control chart limit be is 0.00005
The 95.5% lower control chart limit be is 0.0005.
Given,
The average fraction percent in the past defective as p = 1% = 0.01
Sample size N = 400
Then ,
According to the question ,
95.5% deviation = 2x
We have,
x = [tex]\frac{\sqrt{p (1-p)} }{n}[/tex]
We put these values, into the formula,
x = [tex]\frac{\sqrt{0.01 ( 1 - 0.01) } }{400}[/tex]
= [tex]= \frac{\sqrt{(0.01) (0.99)} }{400}[/tex]
= [tex]\frac{0.99}{400}[/tex]
= 0.0000245
The LCL = p - 2x
= 0.01 - 0.0000245
= 0.00005
The Lower control chart limit be is 0.00005

Which of the following does not state a principle related to why ground wires are an effective safety device? O A. Electronic devices are protected from power surges by having insulated wires. B. Electricity will travel more easily through metal than through insulators. C. When enough electricity builds up, it could pass through highly resistant materials to get to the Earth. D. Electricity always wants to travel "downhill" toward the Earth.
Answers
A; electronic devices are protected from power surges by having insulated wires.
The option that does not state a principle related to why ground wires are an effective safety device is:
A. Electronic devices are protected from power surges by having insulated wires.
Insulated wires protect electronic equipment against power surges, however, this has nothing to do with the usefulness of ground wires as a safety precaution.
The idea of earth wires is to provide a safe conduit for electrical currents to go into the Earth, avoiding harmful electrical potential from building up.
Thus, options B, C, and D all state principles that are directly related to the effectveness of ground wires as a safety device.
Hence, the correct answer is A.

Step-by-step explanation:
There are approximately 7.035 moles of NaCl in 4.23 x 10²⁴ formula units of NaCl.
What is multiplication?Multiplication is a mathematical arithmetic operation. It is also a process of adding the same types of expression some number of times.
Example - 2 × 3 means 2 is added three times, or 3 is added 2 times.
Given:
An expression is 4.23 x 10²⁴
To determine the number of moles of NaCl in 4.23 x 10²⁴ formula units of NaCl:
We need to use Avogadro's number, which is defined as the number of particles (such as atoms, molecules, or ions) in one mole of a substance. Avogadro's number is approximately 6.022 x 10²³ particles per mole.
To convert the given number of formula units of NaCl to moles, we divide by Avogadro's number:
Number of moles of NaCl = (4.23 x 10²⁴ formula units of NaCl) / (6.022 x 10²³ formula units/mol)
Number of moles of NaCl = 7.035 moles (rounded to three decimal places)
Therefore, the required value is 7.035 moles.

As we move along the graph from x = 2 to x = 3 (a change of 1), y decreases from y = 100 to y = 0 (a change of -100). Thus, the slope of this line is
m = rise / run = -100/1 = -100.
The y-intercept is the point where the graph crosses the y-axis, and is (0, 200).
The equation of this line in slope-intercept form is y = -100x + 200
