Use the order of operations to simplify the expression. 5 + 21 ÷ 7 x 2 - 3
Which ordered pair is a solution of the equation? 3x + 3y = -x + 5y
Answer:
Undefined
Step-by-step explanation:
Without option choices, I don't know what the answer could potentially be.
I got X=.5y, and while solving for Y, I came up with 4.5y=4.5y
It has been a few years since I have done this, but I believe the answer is undefined.

The maintenance department at the main campus of a large state university receives daily requests to replace fluorecent lightbulbs. The distribution of the number of daily requests is bell-shaped and has a mean of 47 and a standard deviation of 7. Using the 68-95-99.7 rule, what is the approximate percentage of lightbulb replacement requests numbering between 47 and 68
Answer:
[tex]P(-2<Z<2)=95\%[/tex]
Step-by-step explanation:
From question we are told that
Sample mean [tex]\=x= 47[/tex]
Standard deviation [tex]\sigma =7[/tex]
Generally the X -Normal is given as
[tex]Z=\frac{x-\=x}{\sigma}[/tex]
[tex]Z=\frac{x-47}{9}[/tex]
Analyzing the range
[tex]P(47<x<65) = P(0< z<2.00)[/tex]
[tex]P(47<x<65) = 95/2[/tex]
[tex]P(47<x<65) = 47.5\%[/tex]
Mathematically
[tex]Z_1 =\frac{47-47}{9} =0[/tex]
[tex]Z_2 =\frac{65-47}{9} =2[/tex]
Empirical rule shows that
[tex]P(-2<Z<2)=95\%[/tex]

What is Linear Equation in 1 variable?
The linear equations in one variable is an equation which is expressed in the form of ax + b = 0, where a and b are two integers, and x is a variable and has only one solution
Given data ,
The equation is x + 7/2 = 5x/3
Subtracting 7/2 on both sides , we get
x = 5x/3 - 7/2
x = ( 10x - 21 ) / 6
Multiplying 6 on both sides , we get
6x = 10x - 21
Adding 21 on both sides , we get
6x + 21 = 10x
Subtracting 6x on both sides , we get
4x = 21
Divide by 4 on both sides , we get
x = 21/4
Hence , the solution for x + 7/2 = 5x/3 is x = 21/4

A resistor utilized in a critical electronic component is required to have a resistance of 45 ohms /- 0.32 ohms. The current manufacturer of this resistor has found that its manufacturing process produces a mean value of 50 ohms and has a standard deviation of 0.16 ohms. What would be the C P of this process
Answer:
The value is [tex]CP = 0.667[/tex]
Step-by-step explanation:
From the question we are told that
The resistance is [tex]R = 45 \pm 0.32\ \Omega[/tex]
The mean is [tex]\mu = 50 \Omega[/tex]
The standard deviation is [tex]\sigma = 0.16 \Omega[/tex]
Generally the upper limit of the resistance specified in the question(i.e upper specification limit (USL )) is
[tex]USL = 45 + 0.32 = 45.32 \ \Omega[/tex]
Generally the lower limit of the resistance specified in the question(i.e lower specification limit (USL )) is
[tex]LSL = 45 - 0.32 = 44.68 \ \Omega[/tex]
Generally the CP of the process of manufacturing the resistor is mathematically represented as
[tex]C P = \frac{ USL - LSL }{ 6 * \sigma }[/tex]
=> [tex]CP = \frac{45.32 - 44.68 }{6 * 0.16}[/tex]
=> [tex]CP = \frac{0.64 }{0.96}[/tex]
=> [tex]CP = 0.667[/tex]

At time t ≥ 0, the velocity of a body moving along the s-axis is v = t² -5t +4. When is the body moving backwards
Check comments for multiple choice answers
Answer:
A
Step-by-step explanation:
The velocity of a moving body is given by the equation:
[tex]v=t^2-5t+4 ,\, t\geq0[/tex]
Is the velocity is positive (v>0), then our object will be moving forwards.
And if the velocity is negative (v<0), then our object will be moving backwards.
We want to find between which interval(s) is the object moving backwards. Hence, the second condition. Therefore:
[tex]v<0[/tex]
By substitution:
[tex]t^2-5t+4<0[/tex]
Solve. To do so, we can first solve for t and then test values. By factoring:
[tex](t-4)(t-1)=0[/tex]
Zero Product Property:
[tex]t=1, \text{ and } t=4[/tex]
Now, by testing values for t<1, 1<t<4, and t>4, we see that:
[tex]v(0)=4>0,\, v(2)=-2<0,\,\text{ and } v(5)=4>0[/tex]
So, the (only) interval for which v is <0 is the second interval: 1<t<4.
Hence, our answer is A.

Which system of linear equations will have the same solution as that of the given system of linear equations
Answer:
Option 1 is correct.
Step-by-step explanation:
Given two linear equations to us are ,

Answer:
x = 18
Step-by-step explanation:
Given that m is parallel to m, therefore:
(7x - 7)° = (6x + 11)° (alternate exterior angles are congruent)
Solve for x
7x - 7 = 6x + 11
7x - 6x = 7 + 11
x = 18
Joyce says that 4 is a factor of every whole number that has a 4 in the ones place. Nathan says 2 is a factor of every whole number that has a 4 in the ones place. Are they both correct? Complete the following to explain. Joyce is correct For example, 14 has a 4 in the ones place and choose... 4. Choose... Nathan is Choose... Four is Choose... and all numbers with an number in the ones place have Choose... as a factor.
9514 1404 393
Answer:
Joyce is incorrect; 14 is not divisible by 4Nathan is correct; 4 is divisible by 2 and all numbers with 4 in the ones place have 2 as a factor.Step-by-step explanation:
We know that 4 is divisible by 4, and 14 is not. It has to do with 14 = 4 + 10, where 10 does not have 4 as a factor.
On the other hand, both 4 and 14 are divisible by 2. That's because 14 = 4 + 10, where 10 has 2 as a factor.
Joyce is incorrect; Nathan is correct—for the reasons shown above.

81
Irrational:
120
48
pi
The rational numbers are √36, 7/16, and √81 = 9 the irrational numbers are √120, √48, and π.
What is an irrational number?It is defined as the numbers in all real numbers which cannot be represented as rational numbers, in other words the irrational number cannot be expressed in the form of p/q form.
A rational number is a sort of real number that has the form p/q and does not equal zero.
From the definition of rational and irrational number, we can identify the rational and irrational numbers as below:
Rational numbers:
√36 = 6
7/16
√81 = 9
Irrational number:
√120
√48
π
Thus, the rational numbers are √36, 7/16, and √81 = 9 the irrational numbers are √120, √48, and π.

Answer:
D) b + 6 = 17; b = 11
Step-by-step explanation:
Marco checked out a total of 17 items. It is given that 6 of them are movies. Set the equation. Let b = the amount of books checked out:
Whole = Part A + Part B
Whole = 17
Part A = movies = 6
Part B = books = b
17 = 6 + b
Isolate the variable, b. Note the equal sign, what you do to one side, you do to the other. Subtract 6 from both sides:
17 (-6) = 6 (-6) + b
b = 17 - 6
b = 11
D) b + 6 = 17; b = 11 is your answer.
