trig: Solve Quadratic Equations by Factoring help with 2b and 2c
Answer:
2b)x=1/3 or x= -4
2c) x= 0 or x= -2/3
Step-by-step explanation:
To factor ax² + bx + c, use the AC method.
Multiply a and cFind factors of ac that add up to bDivide those two factors by a. Reduce the fractions.The numerators are the constants, and the denominators are the coefficients.(b) 3x² + 11x − 4 = 0
a = 3, b = 11, c = -4ac = (3)(-4) = -12Factors of -12 that add up to 11 are 12 and -1.Divide by 3: -1/3 and 12/3 = 4/1The factors are 3x − 1 and x + 4.(3x − 1) (x + 4) = 0
3x − 1 = 0, or x + 4 = 0
x = 1/3, or x = -4
(c) 12x² + 8x = 0
Here, you can simply factor the greatest common factor, 4x.
4x (3x + 2) = 0
4x = 0, or 3x + 2 = 0
x = 0, or x = -2/3
what is formula for circumfrences
The circumference of a circle, which is another way of saying the perimeter of a circle, can be found using the formula 2πr.
Note that π represents the irrational number 3.14159... which
rounds to 3.14 and r represents the radius of the circle.
Therefore, since π = 3.14, another way of writing the formula
for the circumference of a circle is 2 · 3.14r or 6.28r.
Answer:
circumference = 2 π r
or
circumference = π d
Step-by-step explanation:
r = radius of a circle
d = diameter
therefore
circumference = 2 π r
or
circumference = π d
The dependent variable y is missing in the given differential equation. Proceed as in Example 1 and solve the equation by using the substitution u = y'.
y'' + (y' )^2 + 4 = 0
Answer:
y = In | cos(2x + c ) | + c
Step-by-step explanation:
y" + (y')^2 + 4 = 0
substituting u = y'
u' + u^2 + 4 = 0
hence : u' = - (u^2 + 4 )
[tex]\frac{u'}{-(u^2 + 4)}[/tex] = 1 ------- (1)
integrating both sides of the equation 1
[tex]1/2 \int\limits^1_1 {\frac{2du}{(u^2+4)} } \, = x + c[/tex]
x + c = [tex]- \frac{1}{2} arc tan (\frac{u}{2} )[/tex] hence u = -2 tan(2x + c )
remember u = y'
y' = -2 tan(2x + c) ------ (2)
integrating both sides of the equation 2
y = ∫ [tex]\frac{-sin u}{cos u } du[/tex]
therefore Y = In | cosu | + c
y = In | cos(2x + c ) | + c

Businesses in a country are listed by size: small, medium, and large. Explain why business size is an example of an ordinal-scaled variable. A. The size of a business is ordinal-scaled because it has numerical values that arise from a measuring process. B. The size of a business is ordinal-scaled because it has values that represent quantities. C. The size of a business is ordinal-scaled because it has values that can be used as an order or rank of a categorical variable. D. The size of a business is ordinal-scaled because it has numerical values that arise from a counting process.
Answer: C. The size of a business is ordinal-scaled because it has values that can be used as an order or rank of a categorical variable.
Step-by-step explanation: Ordinal variables are simply categorical in nature just like nominal variables, however, the difference exists in the fact that ordinal labels posses an ordered rank or level unlike nominal variables. Though the extent or width of the difference between these labels cannot be ascertained. In the scenario above, size of businesses are labeled qualitatively with labels such as : small, medium and large. This labels depicts and follow a certain order with small being the least, then medium, then large. Telling us large businesses are superior in size to small and medium and medium is superior to large. Though the extent of the difference cannot be accurately ascertained.
Tell whether x and y show direct variation. Explain your reasoning. x=y+2
Answer:
x and y do not show direct variation
Step-by-step explanation:
Two quantities x and y show direct variation when
y = kx
and k ≠ 0
Given x = y + 2
Making y the subject of the formula:
y = x - 2
The equation above cannot be written in the form y = kx
This means that x and y are not in a proportional relationship
For instance, let's say when x = 4
y = (4) - 2 = 2
Now, if x is doubled, x = 8
y = (8) - 2 = 6
Therefore, doubling x does not necessarily double y, hence they are not in a direct variation.
An ice cream shop offers three flavors of ice cream (vanilla, chocolate, and strawberry), and four toppings (caramel, chocolate sauce, nuts, and sprinkles). If a small sundae includes one scoop of ice cream and two different toppings, how many possible sundaes are there?
Hey there! I'm happy to help!
Let's pretend that we are building a small sundae. We have 3 choices of ice cream flavors.
Now, we want to pick a topping. We have 4 choices here.
After we choose a topping, we can pick another. We only have 3 choices now because we need different toppings, and we already used one.
We want to find how many possible combos we can make. What we do is multiply all of these numbers of choices, and this will show us how many possible sundaes there are.
3×4×3=36
Therefore, there are 36 different sundaes that can be made.

You roll a die. If it comes up a 1 or 2, you win $200. If not, you get to roll again. If you get a 1 or 2 the second time, you win $100. If not, you lose. a) Create a probability model for the amount you win. b) Find the expected amount you'll win.
On the first roll, you have a 1/3 probability of rolling a 1 or 2 and thus winning $200.
There's a 2/3 probability of not rolling a 1 or 2 on the first roll. On the second roll, there is again a 1/3 probability of rolling a 1 or 2, and 2/3 probability otherwise, so that there is a 1/3*2/3 = 2/9 probability of getting a 1 or 2 and thus winning $100, and 2/3*2/3 = 4/9 probability of losing.
(a) Let [tex]W[/tex] be a random variable representing the winnings from playing the game. It has the probability mass function
[tex]P(W=w)=\begin{cases}\frac13&\text{for }w=\$200\\\frac29&\text{for }w=\$100\\\frac49&\text{otherwise}\end{cases}[/tex]
(b) Compute the expected value of [tex]W[/tex]:
[tex]E[W]=\displaystyle\sum_w w\,P(W=w)=\$200\cdot\frac13+\$100\cdot\frac29+\$0\cdot\frac49\approx\$88.89[/tex]

C. Yes; there are no y-values that have more than one x-value.
O
D. No; the graph fails the vertical line test.
Answer: D. No; the graph fails the vertical line test.
The vertical line test is a tool used to determine if we have a function. If we can draw a single straight vertical line through more than one point on the red curve, then the graph is said to have failed the vertical line test. Consequently, this leads to the relation not being a function.
For this circle graph, we can draw a vertical line through more than one point, which is why we don't have a function here.
Put another way, there are inputs (x) that produce more than one output (y), so that's why we don't have a function.

Which statement is true?
A. This scatter plot has no clusters and no outliers.
B. This scatter plot has one cluster and no outliers.
C. This scatter plot has one cluster and three outliers.
D. This scatter plot has one cluster and one outlier.
A cluster is a small group of dots close together. An outlier is a single dot far away from the rest of the dots.
The above graph has a small cluster around y 6&7 and has an outlier at (9,5)
The answer should be D.
Answer:
The correct answer is D. This scatter plot has one cluster and one outlier.
Step-by-step explanation:
From looking at the scatterplot, the majority of the points are collected on the upper left side of the coordinate grid, creating a cluster. This just means that these data points are located close to one another.
If we continue to look at the scatterplot, we can see that there is one data point at approximately (9, 5.25) that is very far from the other data points. This point is considered to be an outlier because it does not follow the general trend of the other data points and changes the data analysis significantly if included in the calculations.

A retailer is having a promotional sale for 35% off all items. There is a 7% sales tax added to the price. Which
represents the situation, where x is the original cost of the item(s)?
Answer:
0.6955x
Step-by-step explanation:
Given the following :
Promotional discount on items = 35%
Sales tax on items = 7%
Original cost of items = x
First we obtain the cost of item after the promotional discount is applied
Cost of item :
Original price - (original price * promotional discount)
x - (x * 0.35) = x - 0.35x
Cost of item = 0.65x
Then the sales tax is added :
Total amount after tax:
Cost of item + (cost of item × sales tax rate)
0.65x + (0.65x * 0.07)
0.65x + 0.0455x
= 0.6955x
Answer:
0.6955x

In (1,2), 1 is is x so any number added to it goes to the right or left. 2 is y so any number added to it goes up or down. It says translate right 5 units so that will be for x, a.k.a 1.
1+5= 6 (new x)
Same with y, a.k.a 2. It says up 3 units, so it must mean add on to y.

A statistical study reported that a drug was effective with a p-value of .042.
a. An effective or ineffective sample may be found about 42 times in 1000 samples. (effective or ineffective)
b. The drug is evidently effective at alpha ? = 0.05. (Yes or No)
c. How would that compare to a drug that had a p-value of .087? (More Effective or Less Effective)
Answer:
(a) An ineffective sample may be found about 42 times in 1000 samples.
(b) Yes, the drug is evidently effective at alpha = 0.05.
(c) A drug that had a p-value of 0.042 is more effective in comparison to a drug that had a p-value of 0.087.
Step-by-step explanation:
We are given that a statistical study reported that a drug was effective with a p-value of 0.042.
Let the Null Hypothesis, [tex]H_0[/tex] : The drug was ineffective.
Alternate Hypothesis, [tex]H_A[/tex] : The drug was effective.
(a) An ineffective sample may be found about 42 times in 1000 samples.
(b) As we know that, if the P-value is less than the level of significance, then we have sufficient evidence to reject our null hypothesis.
SO, here also; the P-value is less than the level of significance as 0.042 < 0.05, so we reject our null hypothesis and conclude that the drug is evidently effective.
(c) The drug that had a p-value of 0.087 would be ineffective as in this case the P-value is more than the level of significance as 0.087 > 0.05, so we do not reject our null hypothesis and conclude that the drug is evidently ineffective.
This means that a drug that had a p-value of 0.042 is more effective in comparison to a drug that had a p-value of 0.087.
