Answer:
The answer is either5x+3 = 4x-3
Answer:
x = -27
Step-by-step explanation:
5 ( x + 3 ) = 4 ( x - 3 )
5 times x, 5 times 3, 4 times x, 4 times -3 =
5x +15 = 4x -12
Subtract 15

Evaluate the following expression when t= 2 .
t² – 44 - 4
Help please
Answer:
-44
Step-by-step explanation:
So you want to plug 2 in for t, so the equation should now look like:
[tex]2^{2}[/tex] - 44 - 4
No all you have to do is solve
[tex]2^{2}[/tex] = 4
4 - 44 = -40
-40 - 4 = -44
Answer:
-44
Step-by-step explanation:
t=2, t² - 44 - 4
1. substitute in the value to the variable: 2² - 44 - 4
2. using PEMDAS, solve the equation: 2² - 44 - 4 = 4-44-4 = -40-4= -44

Mario is walking away from a motion detector at a rate of 1.5 feet per second. He started recording his distance from the motion detector when he was 2 feet in front of the motion detector. Fill in the blank in the sentence below. Mario is 11 feet from the motion detector at ____ a seconds
Answer:
6 seconds
Step-by-step explanation:
Initial distance of Mario from motion detector = 2 ft
Speed of Mario = 1.5 ft/sec
Total distance of Mario from motion detector = 11 ft
Total distance moved by Mario while walking at the rate of 1.5 ft/sec = 11 - 2 = 9 ft
Given that:
Distance = 9 ft
Speed = 1.5 ft/sec
Formula:
[tex]Distance = Speed \times Time[/tex]
[tex]\Rightarrow 9 =1.5 \times Time\\\Rightarrow Time = \dfrac{9}{1.5}\\\Rightarrow Time = \bold{6\ sec}[/tex]
So, at 6 seconds, Mario will be 11 ft from the motion detector.

When purchasing bulk orders of batteries, a toy manufacturer uses this acceptance sampling plan: Randomly select and test 41 batteries and determine whether each is within specifications. The entire shipment is
accepted if at most 3 batteries do not meet specifications. A shipment contains 7000 batteries, and 3% of them do not meet specifications. What is the probability that this whole shipment will be accepted? Will almost
all such shipments be accepted, or will many be rejected?
The probability that this whole shipment will be accepted is 0.9660
(Round to four decimal places as needed)
The company will accept 96.6 % of the shipments and will reject 34% of the shipments, so almost all of the shipments will be accepted
(Round to two decimal places as needed.)
Answer:
Probability that the whole shipment will be accepted = 0.9660
96.60% of the shipment will be accepted
Almost all the shipments will be accepted
Step-by-step explanation:
We are given;
n = 41
p = 3% = 0.03
x = 3
This is a binomial probability question and we will use the formula;
P(X = x) = [n!/(x!(n - x)!)] × p^(x) × (1 - p)^(n - x)
The probability that the whole shipment will be accepted is given by the form;
P(X ≤ 3) = P(0) + P(1) + P(2) + P(3)
P(3) = [41!/(3!(41 - 3)!)] × 0.03³ × (1 - 0.03)^(41 - 3)
P(3) = 0.09046
P(2) = [41!/(2!(41 - 2)!)] × 0.03² × (1 - 0.03)^(41 - 2)
P(2) = 0.22496
P(1) = [41!/(1!(41 - 1)!)] × 0.03¹ × (1 - 0.03)^(41 - 1)
P(1) = 0.36373
P(0) = [41!/(1!(41 - 0)!)] × 0.03^(0) × (1 - 0.03)^(41 - 0)
P(0) = 0.28684
Thus;
P(X ≤ 3) = 0.28684 + 0.36373 + 0.22496 + 0.09046
P(X ≤ 3) = 0.96599 ≈ 0.9660
It means that 96.60% will be accepted

Which of the following best describes the relationship between (x + 2) and
the polynomial 3x2 - x - 14?
A. It is impossible to tell whether (x + 2) is a factor.
B. (x + 2) is not a factor.
C. (x + 2) is a factor.
The factor theorem indicates that the expression (x + 2) is a factor of the polynomial, f(x) = 2·x² - x - 14, because, f(-2) = 0, the correct option is option C.
C. (x + 2) is a factor.
What is the factor theorem?The factor theorem, which is a unique example of the remainder theorem, indicates that the link between the factors and the zeros of the polynomial, such that (x - α) is a factor of the polynomial f(x), if and only if we get f(α) = 0.
The polynomial is; 3·x² - x - 14, the expression is; (x + 2)
The factor theorem indicates that we get, (x - a) is a factor of the polynomial of nth degree, where, n ≥ 1, if f(a) = 0
Whereby the polynomial is expressed as f(x) = 3·x² - x - 14 = 0, we get;
(x + 2), is a factor of the polynomial, according to the factor theorem, if we get, f(-2) = 0
Plugging in x = -2, in the polynomial, we get;
f(-2) = 3×(-2)² - (-2) - 14 = 0
Therefore, (x + 2) is a factor of the polynomial
The correct option is therefore;
C. (x + 2) is a factor

The monomial (x + 2) is a factor of the polynomial, the correct option is C.
How to find the relation?We want to find the relationship between (x + 2) and the polynomial:
P(x) = 3x^2 - x - 14
The monomial (x + 2) will be a factor of the polynomial only if x = -2 is a zero of the polynomial, so let's check that.
P(-2) = 3*(-2)^2 - (-2) - 14
P(-2) = 3*4 + 2 - 14 = 0
So -2 is a zero of the polynomial, then we the monomial (x + 2) is a factor of the polynomial.
The correct option is C.

d = 5x + 10xf solve literal equation for x
Answer:
[tex]x=\dfrac{d}{(5+10f)}[/tex]
Step-by-step explanation:
The given equation is :
d = 5x + 10xf
We need to solve the above equation for x.
Taking x common from RHS,
d=x(5+10f)
Dividing both sides by (5+10f),
[tex]x=\dfrac{d}{(5+10f)}[/tex]
Hence, this is the required value of x.
