Answer:
Slope is: y = 6x-4
Step-by-step explanation:
Divide both sides by 2 and you'll get the answer.
Answer:
6
Step-by-step explanation:
a slope equation. is y = mx + b
first you have to get y by itself by dividing both sides by 2
your new equation is
y= 6x + - 4 or just y = 6x - 4
the slope is the m value and in this case its 6

The state education commission wants to estimate the fraction of tenth grade students that have reading skills at or below the eighth grade level. In an earlier study, the population proportion was estimated to be 0.21. How large a sample would be required in order to estimate the fraction of tenth graders reading at or below the eighth grade level at the 90% confidence level with an error of at most 0.03
Answer:
A sample of 499 is needed.
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]1-\alpha[/tex], we have the following confidence interval of proportions.
[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
In which
z is the zscore that has a pvalue of [tex]1 - \frac{\alpha}{2}[/tex].
The margin of error is given by:
[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
In this question, we have that:
[tex]\pi = 0.21[/tex]
90% confidence level
So [tex]\alpha = 0.1[/tex], z is the value of Z that has a pvalue of [tex]1 - \frac{0.1}{2} = 0.95[/tex], so [tex]Z = 1.645[/tex].
How large a sample would be required in order to estimate the fraction of tenth graders reading at or below the eighth grade level at the 90% confidence level with an error of at most 0.03
We need a sample of n, which is found when [tex]M = 0.03[/tex]. So
[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
[tex]0.03 = 1.645\sqrt{\frac{0.21*0.79}{n}}[/tex]
[tex]0.03\sqrt{n} = 1.645\sqrt{0.21*0.79}[/tex]
[tex]\sqrt{n} = \frac{1.645\sqrt{0.21*0.79}}{0.03}[/tex]
[tex](\sqrt{n})^2 = (\frac{1.645\sqrt{0.21*0.79}}{0.03})^2[/tex]
[tex]n = 498.81[/tex]
Rounding up
A sample of 499 is needed.
Why is it so hard to solve problems in your head after middle school?
Answer:
Because your sleep deprived and your head is clumped up with more equations. :( i wish school was easy
Step-by-step explanation:
Answer:
It is complicated to answer but there are several factors which contribute toward the difficulty of learning how to solve problems. A person's motivation (anxiety) and poor understanding of the how and why of the material. But there are more internal factors as well, mental and metal learning handicaps. For example, Dyscalculia is a common condition where individuals have issues with making basic calculations and using those numbers the way their peers do. (Dyslexia, ADD/ADHAD, Dysgraphia, and Dyspraxia are other examples.

Assign a probability to the following event, and give the method used to assign it: What is the probability that a randomly selected day of the week will be a Friday
Answer:
[tex]\frac{1}{7}[/tex]
Step-by-step explanation:
We know, that probability of an event E, is [tex]\textrm{P}(\textrm{E})=\frac{\textrm{Number of favorable outcomes}}{\textrm{Total number of outcomes}}[/tex].
Here, there are [tex]7[/tex] days in a week.
So, total number of outcomes [tex]=7[/tex].
And only one day, that is, Friday is selected.
So, number of favorable outcomes [tex]=1[/tex].
Therefore, probability [tex]=\frac{1}{7}[/tex].
Hence, the probability that a randomly selected day of the week will be a Friday [tex]=\frac{1}{7}[/tex].
Find the value of x if A, B, and C are collinear points and B is between A and C. AB=6x,BC=x−5,AC=23
Answer:
The value of x = 4 if A, B, and C are collinear points and B is between A and C.
Step-by-step explanation:
We need to find the value of x if A, B, and C are collinear points and B is between A and C.
We have AB=6x,BC=x−5,AC=23
If points are collinear and B is between A and C we can write:
AC=AB+BC
Putting values and finding value of x
[tex]AC = AB+BC\\23=6x+x-5\\23=7x-5\\7x=23+5\\7x=28\\x=\frac{28}{7}\\x=4[/tex]
The value of x = 4 if A, B, and C are collinear points and B is between A and C.

Lucas bought square tiles to retile the
lobby of Town Travel Agency. Each
side of a tile is 11 inches long. If Lucas
uses the formula for the area of a
square, A = s2, how many square
inches will each tile cover?
00 ft.?
Answer:
121 in² ; 0.840 ft²
Step-by-step explanation:
Given that:
Side length of square tile, s = 11 inches
The Area of a square = a² ;
Where a = side length
Hence, we Can get the area of the square tile using the area of square formula :
Area of square tile = 11² = 121 in²
Area in feets :
1 ft² = 144 in²
x = 121 in²
144 x = 121
x = 121 / 144
x = 0.840 ft²

C. (, ) = (9+ 3( − 9), 6 + 3( −6))
D. (, ) = (9+ 3(9− ), 6+ 3(6 − ))
Answer: the answer is D
Step-by-step explanation:I had that question on a quiz
The points after dilation is (27, 18).
What is Dilation?Resizing an item uses a transition called dilation. Dilation is used to enlarge or contract the items. The result of this transformation is an image with the same shape as the original.
Enlargements are dilations that result in a larger image. Reduction is the name for a dilatation that shrinks the image. The initial figure is stretched or contracted by a dilatation.
Given:
Scale Factor= 3
Points (9, 6).
If the coordinates is dilated by factor 3.
Then, (9, 6).
= (9(3), 6(3)).
= (27, 18)
Hence, the points after dilation is (27, 18).

(8,5); perpendicular to 2x - y = 7
Answer:
brainliest plzzz
Step-by-step explanation:
2x - y = 7 is in standard form, and if it were slope-intercept form that would help you. I got the y term by itself:
y = 2x - 7 slope-intercept form. You already know the slope of the perpendicular line is the *negative reciprocal* of the slope you have. So that's (-1/2). The perpendicular line is something like
y = -(1/2)x + b and if you substitute 8 for x and 5 for y you get 9 for b.
y = -(1/2)x + 9 is your perpendicular line. In slope-intercept form. To get back to standard form, start by getting rid of fractions. Multiply both sides by 2.
2y = -x + 18 then add x to both sides.
x + 2y = 18 done.

The figures below are semicircles and squares. Find the perimeter and the area of each shape. Give your answer as a completely simplified exact value in terms of pi (no approximations). Please give both area and perimeter.
Step-by-step explanation:
Perimeter of a semicircle = 0.5πd.
Perimeter of big semicircle = (0.5)(π)(18cm) = 9πcm
Perimeter of 3 small semicircles = (1.5)(π)(6cm) = 9πcm
Hence total perimeter = 9πcm + 9πcm = 18πcm.
Area of a semicircle = 0.5πr²
Area of big semicircle = (0.5)(π)(9cm)² = 40.5πcm²
Area of 3 small semicircles = (1.5)(π)(3cm)² = 13.5πcm².
Hence total area = 40.5πcm² + 13.5πcm² = 54πcm².

Jayson has 97 tickets to give away. He gave 4 tickets to each student in his class and has one leftover.
How many students in his class?
Answer:
4 ; 24
Step-by-step explanation:
A.)
Fixed fee, x = $5
Hourly rate, y = $3
Total rent fee, t= $17
Number of rent hours :
$17 = $5 + $3y
17 - 5 = 3y
12 = 3y
y = 12/3
y = 4 hours
B.)
Total Number of tickets , t = 97
Tickets per student, r = 4
Tickets left = 1
Number of students in class:
(97 - 1) / 4
96 /4
= 24 students
Dan was thinking of a number. Dan divides by 5, then adds 3 to get an answer of 3. What was
the original number?
Answer:
The original number was: x = 0
Step-by-step explanation:
Let 'x' be the number
Given that:
Dan first divides it by 5
x/5
Then adds 3
x/5 + 3
To get an answer of 3
x/5 + 3 = 3
now solving the expression
[tex]\frac{x}{5}+3=3[/tex]
Subtract 3 from both sides
[tex]\frac{x}{5}+3-3=3-3[/tex]
Simplify
[tex]\frac{x}{5}=0[/tex]
Multiply both sides by 5
[tex]\frac{5x}{5}=0\cdot \:5[/tex]
Simplify
[tex]x=0[/tex]
Therefore, the original number was: x = 0
Identify the zeros of the graph of the function g(x).
Answer:
-4 and -2
Step-by-step explanation:
The function has the factors (x + 4) and (x + 2). By setting these both to 0, you will find the zeros of the function.
x + 4 = 0
x = -4
x + 2 = 0
x = -2
Therefore, the zeros of the function are -4 and -2.
