A company manufactures cell phones. In August, a random sample of 125 cell phones was inspected, and 3 phones were found to be defective. The company manufactured 8,000 cell phones in August. Based on the results from the sample, about how many cell phones are expected to be defective?
Answer:
192
Step-by-step explanation:
To find how many phones are expected to be defective, we need to represent the values in a fraction.
[tex]\dfrac{x}{8000}=\dfrac{3}{125}[/tex]
x = number of defective phones
Now we can solve this using algebra.
To get the value of x we need to multiply both sides by 8000 to leave x alone.
[tex]x=\dfrac{3}{125}(8000)[/tex]
[tex]x=0.024(8000)[/tex]
[tex]x=192[/tex]

A. h(x) = 0
B. h(x) = -3^2x
C. h(x) = 2(3^2x)
D. h(x) = 3^x (2 - 3^x)
Answer:
D
Step-by-step explanation:
Function composition substitutes more than just values or constants. It substitutes functions inside another function. Solve each expression by starting inner most and working to outermost. The expression f(x) ∘ g(x) means f(g(x)).
Let f(x) = x(2 - x) and g(x) = 3^x.
Begin by substituting g(x) in for x in f(x).
[tex]f(g(x)) = (3^x)(2-(3^x))[/tex]

You roll a die and flip three coins. The number of possible outcomes in the sample space is.
Answer:
48
Step-by-step explanation:
We assume that the die and coins are non-bias.
If you roll a die once, you have 6 possible outcomes (anything from 1-6).
If you flip 3 coins once, you have 2 possible outcomes for each coin (either heads or tails). Multiply those 3 possibilities (2x2x2), you get 8.
Multiply 8 with 6, and you get 48 possible outcomes in sample space.
*In the sample space shown below, do the same combinations to all roll die outcomes to get the whole sample space (i.e., 2TTT, 3TTT, 4TTT etc.).

Simplify 13 2
the 2 is tiny so I think it's 13 to the power of 2
Answer: 169
Step-by-step explanation:
You just multiply 13 by 13
When simplifying 13 to the power of 2, you multiply 13 by itself, resulting in 13 x 13, which equals 169. This is known as squaring a number.
The question you've asked involves exponents, which is a way to express repeated multiplication of the same number. When you write 13 with a tiny 2 next to it, you're indicating that 13 should be multiplied by itself once, which is what squaring a number means. In other words, 13 to the power of 2 is 132, which is 13 × 13.
Let's simplify 132:
Multiply 13 by itself: 13 × 13.Calculate the product: 169.So, 132 equals 169. This process is using an integer power, which involves multiplying the base (in this case, 13) by itself as many times as indicated by the exponent (in this case, 2). This can apply to any number, where for example 53 (5 cubed) equals 5 × 5 × 5, which is 125.

What is the simplest form of the radical expression 3 sqrt 24 - 2 sqrt 54 + 2 sqrt 18
Please show all of your work.
Answer:
[tex]6\sqrt{2}[/tex]
Step-by-step explanation:
we have
[tex]3\sqrt{24} -2\sqrt{54}+2\sqrt{18}[/tex]
we know that
[tex]\sqrt{24}=\sqrt{2^{3}3}=2\sqrt{6}[/tex]
[tex]\sqrt{54}=\sqrt{3^{3}2}=3\sqrt{6}[/tex]
[tex]\sqrt{18}=\sqrt{3^{2}2}=3\sqrt{2}[/tex]
Substitute
[tex]3(2\sqrt{6}) -2(3\sqrt{6})+2(3\sqrt{2})[/tex]
[tex](6\sqrt{6}) -(6\sqrt{6})+(6\sqrt{2})[/tex]
[tex]6\sqrt{2}[/tex]
When simplifying the square roots in the expression 3sqrt(24) - 2sqrt(54) + 2sqrt(18), we find that the simplified solution is 6sqrt(2).
Explanation:To simplify the radical expression 3 sqrt 24 - 2 sqrt 54 + 2 sqrt 18, we first need to break down each square root into its simplest form. In order to do this, we look for perfect-square factors (numbers like 4, 9, 16, 25 that have an integer as a square root) within each number:
3sqrt(24) = 3sqrt(4*6) = 6sqrt(6)
2sqrt(54) = 2sqrt(9*6) = 6sqrt(6)
2sqrt(18) = 2sqrt(9*2) = 6sqrt(2)
Because the sqrt(6) terms are like terms we can combine those, and then include the sqrt(2) term:
6sqrt(6) - 6sqrt(6) + 6sqrt(2) = 6sqrt(2).

Samantha needs to pay a total of $250 in extra charges, which includes $168 for the state tax, $47 for the license plate, and $35 for the state safety and emission inspection.
Explanation:Calculation of Extra Charges for Automobile PurchaseTo determine how much Samantha needs to pay in extra charges for her automobile purchase, we need to calculate each component separately and then sum them up. Firstly, we calculate the state tax by multiplying the purchase price by the tax percentage:
Tax = Purchase Price × Tax Rate
Tax = $4,200 × 0.04 = $168
Next, we add the fixed costs for the license plate and state safety and emission inspection:
Total Extra Charges = Tax + License Plate Fee + Inspection Fee
Total Extra Charges = $168 + $47 + $35 = $250
Therefore, Samantha needs to pay $250 in extra charges, not including the price of the car.

Answer:
The possible solution that is obtained from the system of equation are:
(1,3) and (6,13)
Step-by-step explanation:
We are asked to find the solution set of the given system of equation as:
[tex]y=x^2-5x+7-----------(1)[/tex]
and [tex]y=2x+1--------(2)[/tex]
We know that the solution of the system of equations is the possible set of x and y-values that satisfy both the equations.
Or we may say the point of intersection of the graph that is obtained from both the equations.
We solve the system by substitution method as:
We put the value of y from equation (1) in equation (2) to obtain:
[tex]x^2-5x+7=2x+1[/tex]
which is further written by combining the like terms as:
[tex]x^2-5x-2x+7-1=0\\\\x^2-7x+6=0\\\\x^2-6x-x+6=0\\\\x(x-6)-1(x-6)\\\\(x-1)(x-6)=0[/tex]
Hence, we get the possible values of x as:
x=1 and x=6
Also the value of y when x=1 is:y=2×1+1=2+1 ( Putting the value of x in equation (2))
y=3
when x=6 we have the value of y as:y=2×6+1
y=13
Hence, the possible solutions are:
(1,3) and (6,13)

Two particle with charges q and −q are fixed at the vertices of an equilateral triangle with sides of length
a. if k = 1/4π 0, the work required to move a particle with charge q from the other vertex to the center of the line joining the fixed particles is:
Answer:
k(qq)/r^2 times the length of the distnace
Step-by-step explanation:
Force times distance. The Electrical force is the only thing you have to find first.
The work required to move a particle with charge q from the other vertex to the center of the line joining the fixed particles is -kq^2/a.
Explanation:To find the work required to move a particle with charge q from the other vertex to the center of the line joining the fixed particles, we need to calculate the electrostatic potential energy. The potential energy is given by the equation:
U = kqQ/r
where U is the potential energy, k is the electrostatic constant, q and Q are the charges, and r is the distance between the charges.
In this case, we have two charges of magnitude q and -q at the vertices of an equilateral triangle. The distance from the center of the triangle to each charge is a/2, where a is the length of the side of the triangle. Therefore, the potential energy is:
U = (1/4πε0)q(-q)/a
where ε0 is the permittivity of free space. Simplifying the expression, we get:
U = -kq2/a

A hot air balloon is flying above Groveburg. To the left side of the balloon, the balloonist measure the angle of depression to the Groveburg soccer fields to be 20° 15'. To the right side of the balloon, the balloonist measures the angle of depression to the high school football field to be 62° 30'. The distance between the two athletic complexes is 4 miles.
What is the distance from the balloon to the football field?
Answer:
The answer is 1.4 miles ⇒ answer (d)
Step-by-step explanation:
* Let the balloon is at the vertex A, and the soccer fields
at vertex B and the football field at vertex C
∴ m∠B = 20° 15' = 20.25°
∴ m∠C = 62° 30' = 62.5°
∴ m∠A = 180 - 20.25 - 62.5 = 97.25°
∵ BC = 4 miles
* By using the sin Rule:
∵ AC/sin(B) = BC/sin(A)
∴ AC = (BC)(sinB)/sin(A)
∴ AC = [4 × sin(20.25)] ÷ sin(97.25) = 1.395 ≅ 1.4 miles
∴ The distance from the balloon to the football filed = 1.4 miles
