9514 1404 393
Answer:
x = -1/8
Step-by-step explanation:
The expression simplifies to ...
-3 -5 = 1/x
-8 = 1/x
x = -1/8
_____
We wonder if you intend ...
(-3)^-5 = 1/x
(-3)^5 = x . . . . . . multiply by x(-3)^5
x = -3^5 . . . . . . . simplify signs
x = -243

The partial factorization of x2-3x - 10 is modeled with algebra tiles. Which unit tiles are needed to complete the factorization? +1 O 2 negative unit tiles O 2 positive unit tiles O 5 negative unit tiles O 5 positive unit tiles +x2 ++X - -x X 1 1
Answer:
B - 2 positive unit tiles
Step-by-step explanation:
The dimensions of tile are (x-5) units and (x+2) units.
What are factors of polynomial?The factors are the polynomials which are multiplied to produce the original polynomial.
The given expression is x²-3x-10.
Here, x²-5x+2x-10
= x(x-5)+2(x-5)
= (x-5)(x+2)
Therefore, the dimensions of tile are (x-5) units and (x+2) units.

The original price of a bicycle was $100.00. In March, a bicycle went on sale for 10% off. In April, the sale price was raised by 10%. What is the price of the bicycle in April? Write just the value that represents your answer.
Answer:
take 10% out of 100 = 90
then find 10% of 90 = 9
add that to 90 = 99
The price of the bike in april is 99$

A quality-assurance worker wants to systematically sample 120 glass jars each day from a conveyor belt in a factory that puts out 3,600 jars each day. If the worker will select every kth jar, what is the best value of k for the worker to use? Enter a whole number.
Answer:
The best value of k for the worker to use is 30.
Step-by-step explanation:
Sample of 120 jars from a set of 3,600.
If the worker will select every kth jar, what is the best value of k for the worker to use?
The best case would be starting at 0 and ending at 3600, finding 120 values, which means that k is given by the division of 3600 by 120. So
[tex]k = \frac{3600}{120} = \frac{360}{12} = 30[/tex]
The best value of k for the worker to use is 30.
A certain type of golfball is tested by a robot that hits the ball with a consistent impact force. The distances this type of ball travels in this test are normally distributed with a mean of 195 meters and a standard deviation of 5 meters. Suppose that quality control experts regularly collect random samples of 25 distance measurements and calculate the sample mean distance in each sample. Assume that the measurements in each sample are independent.
What will be the shape of the sampling distribution of the sample mean distance?
Skewed to the left
(Choice A)
A
Skewed to the left
(Choice B)
B
Skewed to the right
(Choice C)
C
Approximately normal
(Choice D)
D
Unknown; we don't have enough information to determine the shape
Answer:
C Approximately normal
Step-by-step explanation:
Central Limit Theorem
The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
In this question:
Sampling distribution of the sample mean is approximately normal, by the Central Limit Theorem. The correct answer is given by Choice C.

Answer:
y = x^2 + 15x + 56
Step-by-step explanation:
The solutions (where the trinomial = 0) is the factors that will turn the trinomial into 010.
(x + 7)(x + 8) = 0
This means that either -7 will turn the trinomial into 0 or - 8 will.
The trinomial is
x^2 + 8x + 7x + 56 will turn the trinomial to 0.
y = x^2 + 15x + 56 when either - 7 or - 8 is put in for x.
y = (-7)^2 + 15(-7) + 56
y = 49 - 105 + 56
49 + 56 = 105
y = 105 - 105 = 0
y = (-8)^2 - 15(-8) + 56
y = 64 - 120 + 56
y = 120 - 120= 0
No other number will turn the trinomial into 0.

calculate the perimeter of a quarter circle 2mm use pi=3.14
Answer:
Step-by-step explanation:
If the radius of the circle is 2mm, the circumference is 4π mm.
Arc length of the quarter circle = π mm.
Perimeter of the quarter circle = arc length + 2 radii = 4π + 4 mm = 16.56 mm
