Step-by-step explanation:
T=16d=135
The linear equation in slope-intercept form to find Ethan's total weekly pay is T = 16d + 135
A linear equation is in the form:
y = mx + b
where m is the slope of the line, b is the y intercept and y, x are variables.
Let T represent the total money paid to Ethan in a week for d deliveries.
Ethan is paid $16 per delivery, hence m = 16.
T = 16d + b
For 5 deliveries, his total pay was $215. Hence when d = 5, T = 215:
215 = 16(5) + b
215 = 80 + b
b = 135
T = 16d + 135
The linear equation in slope-intercept form to find Ethan's total weekly pay is T = 16d + 135

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 ,
[tex]\qquad 3x + 7y = 10 \\\\ \qquad x + y = 2 [/tex]
And we have to find which system of linear equations have same answer .
On considering option (1) which is ,
[tex]\qquad 3x + 7y = 10 \\\\ \qquad 2x + 2y = 4 [/tex]
On taking the second equation in this ,
[tex]=> 2x + 2y = 4 \\\\=> 2( x + y ) = 4 \\\\=> x+y =\dfrac{4}{2}}\\\\\boxed{\red{\bf => x + y = 2 } }[/tex]
This is same as the second one given in the Question . And the first one is already same .
Hence option (1) is correct .

The distance between Columbia and Savannah is 6.5 inches on a map. If the map scale is 1 inch = 30 miles, what is the actual distance between the towns?
Answer:
195 miles
Step-by-step explanation:
Because if 1 inch= 30 miles you would have to multiply 30 by 6 because there is 6 inches, which is 180. The you have to look at the .5. .5 is half an inch, so you have to divide 30 by 2. you get 15 and then add 15 to the 180 and get 195.

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]

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.

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.

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.

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

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.
