Craig likes to collect video records last year he had 10 records his collection now has 12 records what is the percent increase of his collection
9514 1404 393
Answer:
20%
Step-by-step explanation:
The percentage change in a value is calculated from ...
percent change = ((new value) -(old value))/(old value) × 100%
For your given numbers, this is ...
percent change = (12 -10)/10 × 100% = (2/10)×100% = 20%

Answer:
25, 25, 22.5, 22
Step-by-step explanation:
It gives you a hint; K = y/x. They give you what x and y are so use that to solve for the last row.
We are given all of these values:
x -> 2, 3, 4, 5
y -> 50, 75, 90, 110
Use the formula given and solve for K.
50/2 = 25

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.

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]
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]
What is the solution to the equation x+7/2=5x/3

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

Let f(x) be a continuous function such that f(1)=2 and f(x)= x^3+6 and What is the value of f(5)?(A) 11.446 (B) 13.446 (C) 15.446 (D) 24.672 (E) 26.672 fx x f5
Answer:
the value of f(5) is 26.672
Option (E) 26.672 is the correct answer
Step-by-step explanation:
Given that;
f(1) = 2 and f(x) = √( x³ + 6 )
f(5) = ?
f(5) = f(1) + ₁∫⁵ f'(x) dx
we substitute
f(5) = 2 + ₁∫⁵ √( x³ + 6 ) dx
f(5) = 2 + ₁∫⁵ √( x³ + 6 ) dx
f(5) = 2 + 24.6719
f(5) = 26.672
Therefore the value of f(5) is 26.672
Option (E) 26.672 is the correct answer
The value of f(5) is 26.672
Continuous functions and drivativesGiven the following parameters
f(1) = 2
f(x) = √( x³ + 6 )
We need to calculate the value of f(5) as shown below
f(5) = f(1) + ₁∫⁵ f'(x) dx
Substitute the given parameters
f(5) = 2 + ₁∫⁵ √( x³ + 6 ) dx
f(5) = 2 + ₁∫⁵ √( x³ + 6 ) dx
f(5) = 2 + 24.6719
f(5) = 26.672
Hence the value of f(5) from the solution is 26.672

Answer: False.
Step-by-step explanation: Rational and irrational numbers are the opposites of each other. If a number is rational, it cannot possibly be irrational.
Think about it this way, can a negative number be both negative and positive? No, of course not. This is the exact same concept, albeit using rational and irrational instead of positive and negative. Still, a number can only be one or the other, never both.

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.
