Answer:
x = [tex]\frac{1}{3}[/tex]
Step-by-step explanation:
Step 1: Solve
We can divide 3 from both sides to get "x" by itself
[tex]3x=1\\\frac{3x}{3} =\frac{1}{3} \\x = \frac{1}{3}[/tex]
Therefore x = [tex]\frac{1}{3}[/tex]
Answer:
[tex]\large \boxed{x=\frac{1}{3} }[/tex]
Step-by-step explanation:
[tex]3x=1[/tex]
We need to solve for the x variable. It is best to isolate the variable on one side of the equation to find the value that makes the equation true.
Divide both sides of the equation by 3.
[tex]\displaystyle \frac{3x}{3} =\frac{1}{3}[/tex]
Simplify the equation.
[tex]\displaystyle x=\frac{1}{3}[/tex]

Answer:
Hello
Step-by-step explanation:
From the answer to the second Question...
x²-6x+9 = -13 + 9
Factorize L.H.S
x² - 3x - 3x + 9 = -4
x(x - 3) - 3(x - 3) = -4
(x - 3)(x - 3) = -4
(x - 3)² = -4
Hence the answer is
[tex] \color{purple}{ \boxed{ {(x - 3)}^{2} = - 4}}[/tex]
Answer:
-3 and -4 are the correct answers!!
What are the two types of hypotheses used in a hypothesis test? type I and type II null and alternative Your answer is correct. left-tailed and right-tailed population and sample How are they related? They sum to zero. One is a subset of the other. They are equal. They are complements.
Answer:
There are two types of hypotheses tests. null and alternative
They are complements.
Step-by-step explanation:
There are two types of hypotheses tests. null and alternative
the table shows the summary of both tests.
True Situation DECISION
Accept H0 Reject H0
(or accept Ha)
H0 is true Correct decision Wrong Decision
(no error) type I error
H0 is false Wrong Decision Correct decision
type II error ( no error)
The probability of making a type I error is conventionally denoted by alpha and that of committing a type II error is indicated by beta.
∝ = P ( type I error) = P (reject H0 / H0 is true)
β = P (type II error) = P (accept H0 / H0 is false)
When ∝ becomes larger, β tends to become smaller . There is inverse relationship between ∝ and β.
When H0 is true Ha is false when Ha is false H0 is true. So they are compliments of each other.
Lisa is framing a rectangular painting the length is three more than twice the width she uses 30 inches of framing material what is the length of the painting right and solve the equation
Answer:
The width is 4 inches
The length is 11 inches
Step-by-step explanation:
Let the width be x inches
Let the length be (2x+3 )inches
Perimeter= 30 inches
therefore, 2(length +breadth)= perimeter
=>2(2x+3+x)=30
=>2(3x+3)=30
=>6x+6=30
=>6x=30-6
=>6x=24
=>x=24/6
=>x=4
The width is 4 inches
The length is 11 inches
To solve this question:
First, we have to understand the concept of perimeter, and how it is calculated for a rectangle.Relating the length and the width of the triangle, and using this to solve the perimeter equation for the length.Doing this, we get that the length of the painting is: 11 inches.
Perimeter of a rectangle:
The perimeter of a polygon is the sum of it's sides.
For a rectangle, as the one given in the picture at the end of this answer, which is of the format of the painting, the perimeter is given by:
[tex]P = 2l + 2w[/tex]
Lisa is framing a rectangular painting the length is three more than twice the width.
This means that:
[tex]l = 3 + 2w[/tex]
Since we want to solve for the length, we write the width as a function of the length, thus:
[tex]2w = l - 3[/tex]
She uses 30 inches of framing material
This means that the perimeter is of 30 inches, that is:
[tex]2l + 2w = 30[/tex]
Since [tex]2w = l - 3[/tex]
[tex]2l + l - 3 = 30[/tex]
[tex]3l = 33[/tex]
[tex]l = \frac{33}{3}[/tex]
[tex]l = 11[/tex]
Thus, the length of the painting is of 11 inches.

A preferred stock pays an annual dividend of $6.75 and sells for $58.60 a share. What is the rate of return on this security?
Answer:
11.52%
Step-by-step explanation:
Price (p0) = 58.6
Dividend (D1) = 6.75
P0= D1/ke
58.6 = 6.75/ke
ke = 6.75/58.6
ke = 0.1152 or 11.52%
Rate of return (ke) = 11.52%

Abel and Cedric will share a total of $180. Abel will receive half as much as Cedric. What amount. in dollars, will Cedric receive (Disregard the $ sign when gridding your answer.)
Answer:
Cedric's share=$120
Abel's share=$60
Step-by-step explanation:
Abel will receive half as much as Cedric
Let
Cedric's share=x
Abel's share = 1/2 of x
Total money=$180
x + 1/2x = 180
2x+x/2 =180
3/2x=180
Divide both sides by 3/2
x= 180÷3/2
=180 × 2/3
=360/3
=120
Therefore,
Cedric's share = x = 120
Abel's share=1/2x
=1/2 × 120
=120/2
=60
Cedric's share=$120
Abel's share=$60

Which of the following statments is true regarding the solutions to the quadratic equation 5x^2 +6x+2=0? See picture
Answer:
The quadratic equation has two complex solutions.
Step-by-step explanation:
5x² + 6x + 2 = 0
To know the the correct answer to the question, we shall determine the discriminant of the equation. This can be obtained as follow:
5x² + 6x + 2 = 0
ax² + bx + c = 0
Comparing the above equation, we can obtain:
a = 5
b = 6
c = 2
Discriminant (D) =?
D = b² – 4ac
D = 6² – (4 × 5 × 2)
D = 36 – 40
D = – 4
Since the discriminant of the equation is less than 0, it means that the equation has no real root ( i.e the equation has two complex solution).

A recipe for chocolate chip cookies calls for 1 1/4 cups of flour. If you are making 2 2/3 recipes, how many cups of flour are needed?
(Simplify your answer. Type a whole number, reaction, or mixed number.)
Answer:
2 2/3 cups of flour
Step-by-step explanation:
To answer this question you need to multiply 1 1/4 by 2 2/3
To multiply first make each mixed number an improper fraction
This means multiplying the whole number by the denominator, then adding the numerator
For example 1 1/4 would become 5/4 because 4 x 1 = 4 and 4 + 1 = 5, & 2 2/3 would be 8/3
Now multiply the numerator and denominator (5/4 x 8/3)
30/12 simplified to 8/3 (2 2/3)

One-way Analysis of Variance uses a F test to compare the variance between the treatment level means to the error variance (the pooled variance within levels). For this test, one assumption is that the observations are random samples drawn from normally distributed populations with unequal variances.TrueFalse
Answer:
False
Step-by-step explanation:
The assumption of ANOVA are:
1) the k- samples are selected randomly and independently from the respective populations
2) All the k population from which samples are drawn are normally distributed with means u1,u2, u3,........
3) the observations are random samples drawn from normally distributed populations with equal variances. The technical term for this assumption is Homoscedasticity.
Failure of any assumption will impair the technique. However, minor deviations can be tolerated. Sometimes square roots and logs are used to make assumptions true.

Assume that the amount of time that it takes an employee to service a car at an oil change facility follows the uniform probability distribution between 21 and 38 minutes. What is the probability that a randomly selected car will require less than 25 minutes to service?
Answer:
The probability is [tex]P(X < 25) = 0.308[/tex]
Step-by-step explanation:
From the question we are told that
The amount of time is uniform probability distribution between 21 and 38 minutes.
Given that the amount of time is uniformly distributed then the probability that a randomly selected car will require less than 25 minutes to service is mathematically evaluated as
[tex]P(X < 25) = \frac{ 25 - 21}{38 - 21}[/tex]
=> [tex]P(X < 25) = 0.308[/tex]
The $x$-intercept of a positively-sloped line is -5, and the area of the triangle formed by the line, the $x$-axis, and the $y$-axis is 10. What is the slope of the line?
Answer:
4/5 OR -4/5
Step-by-step explanation:
So, area of triangle = 1/2 * base * height
base = 5 (because x-axis is base, x-intercept is -5, so x-length = 5)
height is unknown
area = 10
We can form the equation: 1/2 * 5 * height = 10
Rearrange terms to get: height (y-height) = 10 / (0.5 * 5) = 4
Following the formula for gradient, dif in y / dif in x, we get 4/5
Therefore our gradient is (4/5), or 0.8.
But because we are only told the x-intercept, it can cross the y axis at y = 4 or y = -4. So there are actually 2 possible gradients, 4/5 and -4/5
