Answer:

Hey there!

Let x be the price of lipstick

Let 1/2x be the price of shampoo

1.5x=20

x=13.33

1/2x=6.67

The shampoo costed $6.67, and the lipstick costed $13.33

Let me know if this helps , or if you have any more questions :)

Answer:

Thank shampoo costed $7.50 and the lipstick costed $15

Step-by-step explanation:

So if you subtract 15 by 50  you get 35 dollars. Then if you divide 35 by 2 you get 15.5 but the .5 is no important right now. So that's how you get 15 dollars for the lipstick and the shampoo was $7.50. The purse was $12.50.

Answer:

0.0482

Step-by-step explanation:

Given the following :

Probability of success : p(success) = 0.25

Number of trials = 800

X = number of successes

Calculate P(X > 220)

The problem above can be solved using the binomial probability formula:

P(X > 220) = P(X = 221) + P(X =222)... + P(X =800)

To save computation time, we coild use the online binomial probability calculator :

P(X > 220) = 0.0482

The binomcdf function of a graphing calcukatur can also be used :

1 - binomcdf(800, 0.25, 220)

1 - (0.95177363855) = 0.04822

Step-by-step explanation:

Answer: a. Multicollinearity occurs when two or more independent variables are highly correlated.

Step-by-step explanation:

Multicollinearity usuall occurs when an independent variables in a regression model is correlated. This correlation is a problem which occurs because independent variables should be independent. If the degree of correlation between variables is high enough, it would cause problems when you fit the models or try to interpret the results.

According to the statement of multicollinearity, option b is the correct answer it occurs when two or more independent variables are highly correlated.

Multicollinearity refers to the occurrence of two or more independent variables which are highly correlated with one another in a regression model.

The statement means that in a regression model, independent variables can be predicted from another independent variable.

For example,

Multicollinearity can also occur when new dependent variables are created which are dependent on others.

It can be an issue when the regression model is only being used to understand the relationship. It is unable to distinguish between the separate effect of an independent variable on the dependent one.

So, option a is correct in that is multicollinearity occurs when two or more independent variables are highly correlated.

Answer:

Step-by-step explanation:

if f(x) = 1/(x+1)

the f(f(x)) means, wherever you see an "x" in the function.

plug in the function again.

so plug in "1/(x+1)" wherever you see an x

so...

1/(f(x) + 1)  

1/((1/(x+1))+1)

now you're going to need to fix the denominator.  

at the moment... this is what you're denominator looks like.

1/(x+1) + 1

so, combine them. find the LCD

LCD = x + 1

1/(x + 1) + x + 1 / x + 1

x + 2 / x + 1

that's your new denominator.

f(f(x)) = 1 / (x + 2 / x + 1)

because it's 1 / something. all you need to do is get the reciprocal of that "something"

so, what's the reciprocal of x + 2 / x + 1?

x + 1 / x + 2

that's your final answer.

next one.

remember, same deal, everywhere you see an "x" plug in the original function.

f(x) = x/(x+1)

f(f(x)) = f(x) / ( f(x) + 1 )  

= [x / (x + 1) ] / [ (x / (x + 1) ) + 1 ]

so, right now this is your denominator.

(x / x + 1) + 1

combine, find the LCD, LCD = x + 1

x / x + 1  +  x + 1 / x + 1

2x + 1 / x + 1

that's your new denominator.

so plug it in.  

[x / (x + 1) ] / [2x + 1 / x + 1]

this is a little more complicated. but remember, whenever you divide by a fraction, it's the same as multiplying by it's reciprocal

so...

rewrite it like this.

x / (x + 1) * (x + 1) / 2x + 1

the x + 1 cancel out.

and you're left with

x / 2x + 1

hope that helps!

Answer:

9. Juanita's recipe.

10. Leon's recipe.

Step-by-step explanation:

9.  All you need to do is convert the numbers into fractions.  

Juanita's recipe: 4 parts lemon, 2 parts sugar.  Lydia's recipe: 5 parts lemon  and 3 parts sugar.  So in order to find the lemon amount in each recipe convert into this fraction:

lemon/sugar

Juanita: lemon/sugar= 4 lemon/2 sugar

Lydia: lemon/sugar= 5 lemon/3 sugar

The LCM is 6 so that is the denominator.

Juanita: 4 lemon/2 sugar= 12 lemon/6 sugar

Lydia: 5 lemon/3 sugar= 10 lemon/6 sugar

The ratio is 4:2= ?:6 and 5:3= ?:6

Juanita has 12 lemon and Lydia has 10, so Juanita has more lemons.

10.  Same as number 9.

Use the fraction peanuts/pretzels because it wouldn't work if peanuts is on the bottom otherwise both Leon and Cisco's peanut amount will be the same.  SO put peanuts over pretzels, so pretzels will be the denominator so we can find the peanut amount.

peanuts/pretzels

Leon: peanuts/pretzels= 3 peanuts/8 pretzels

Cisco: peanuts/pretzels= 2 peanuts/6 pretzels

The LCM is 24 so that is the denominator.

Leon: 3 peanuts/8 pretzels= 9 peanuts/24 pretzels

Cisco: 2 peanuts/6 pretzels= 8 peanuts/24 pretzels

The ratio is 3:8= ?:24 and 2:6= ?:24

Leon has 9 peanuts and Cisco has 8, so Leon has more peanuts.

Answer:

D) 1/16

Step-by-step explanation:

1/6*3/8=3/48

reduced, it’s 1/16

Answer:

1/16

Step-by-step explanation:

A cube is tossed.

The possible outcomes: {1, 2, 3, 4, 5, 6} => 6 possible outcomes in total.

The event of occurring a number 3: {3} => 1 possible outcomes.

=> P(3) = number of possible outcome of event/ total possible outcomes = 1/6

A spinner is spun.

The possible outcomes: {A, A, A, A, B, C, C, C} => 8 possible outcomes in total.

The event of occurring letter C: {C, C, C} => 3 possible outcomes.

=> P(C) = number of possible outcome of event/ total possible outcomes = 3/8

The event of occurring 3 and the event of occurring C are two independent events because tossing a cube does not affect spinning a spinner. Then, we have:

P(3 and C) = P(3) x P(C) = (1/6) x (3/8) = 3/48 = 1/16

Answer:

x=10 84 cm

Step-by-step explanation:

We know that a square has 4 sides, and each side length is (2x+1). So we need to distribute the 4.

4(2x+1)

8×+4 is the perimeter for the square.

A triangle has 3 sides, and each side length is (3x-2). So we need to distrbute the 3.

3(3x-2)

9x-6 is the perimeter of the triangle.

We know that these perimeters are equal to each other. Then we just solve for x.

8x+4=9x-6

10=x

Plug 10 into the square equation.

8(10)+4

84 cm

Answer:

x = 10

Square perimeter = 84cm

Triangle perimeter = 84cm

Step-by-step explanation:

Hello!

First, we make an equation to find the perimeter of each shape

For a square we multiple one side by 4

(2x + 1) * 4

Simplify

8x + 4

An equilateral triangle means each side is equal so we can multiply one side by 3

(3x - 2) * 3

Simplify

9x - 6

The problem states they are equal to each other so we can show that

8x + 4 = 9x - 6

Now we can solve for x

Subtract 8x from both sides

4 = x - 6

Add 6 to both sides

10 = x

Now we can put x into our original equations for the perimeters

Square

8(10) + 4

80 + 4

84cm

Triangle

9(10) - 6

90 - 6

Answer:

B. Since there is an extreme value (5) and no big gaps in the middle of the data, the median best represents the data.

Step-by-step explanation:

Let's evaluate each answer choice.

For reference, the data set is 90, 79, 5, 84, 95, 81 , 87, 94

From least to greatest: 5, 79, 81, 84, 87, 90, 94, 95

A. Since the data has many repeated values, the mode best represents the data.

⇒ The data set has no repeated values. Therefore, this answer choice cannot be correct.

B. Since there is an extreme value (5) and no big gaps in the middle of the data, the median best represents the data.

⇒ This choice is correct. 5 is an extreme value. If we were to arrange the data from the least to greatest, the middle numbers would all be around 80 to 90 ( no big gaps).

C. Since there are no extreme values, the mean best represents the data.

⇒This data set does have an extreme value. There is a 5 in the mix of 80s and 90s. So, this answer is not correct.

D. Since there are no extreme values and few repeated numbers, the median best represents the data.

⇒ As previously mentioned, there is an extreme value of 5. We can eliminate this choice.

Therefore, the best answer choice is B. Since there is an extreme value (5) and no big gaps in the middle of the data, the median best represents the data.

Solving for the variable, x: [tex]x = \frac{1}{3}y + \frac{2}{3}[/tex]

Solving for the variable, y: [tex]y = 3x - 2[/tex]

Step-by-step explanation:

IF:

You are solving for the variable, x. Note the equal sign, what you do to one side, you do to the other. Isolate the variable, x. First, follow PEMDAS, then do the opposite of PEMDAS.

First, distribute 2 to all terms within the parenthesis:

(3x - y = 2) * 2 = (6x - 2y = 4)

Next, solve for x. Add 2y to both sides:

6x - 2y (+2y) = 4 (+2y)

6x = 4 + 2y

Next, divide 6 from both sides:

(6x)/6 = (4 + 2y)/6

x = (2y)/6 + (4)/6

x = (1/3)y + (2/3)

IF:

You are solving for the variable, y. Note the equal sign, what you do to one side, you do to the other. Isolate the variable, y. First, follow PEMDAS, then do the opposite of PEMDAS.

First, distribute 2 to all terms within the parenthesis:

(3x - y = 2) * 2 = (6x - 2y = 4)

Next, solve for  y. Subtract 6x from both sides:

6x - 2y = 4

6x (-6x) - 2y = 4 (-6x)

-2y = -6x + 4

Then, divide -2 from both sides:

(-2y)/-2 = (-6x + 4)/-2

y = (-6x)/-2 + (4)/-2

y = 3x + (-2)

y = 3x - 2

Answer:

$3,015

Step-by-step explanation:

To determine the amount that you will have in 6 years, you have to use the formula to calculate the future value:

FV=PV*(1+i)^n

FV= future value

PV= present value= $1,900

i= interest rate= 8%

n= number of periods of time= 6 years

FV=1,900*(1+0.08)^6

FV=1,900*(1.08)^6

FV=3,015

According to this, the answer is that in 6 years you will have $3,015 in your retirement account.

Form: Linear Direction: Positive Strength: Moderate

Step-by-step explanation:

The scatter plot for the Cost of Airplane Ticket versus the number of Miles Flown is attached below.

It can be easily seen that the plot is moving in an upward directions. An upward moving scatter plot represents a positive relationship between the two variables.

Similarly, the scatter plot here represents a positive relationship between cost of airplane ticket and the number of miles flown.

Now consider the points plotted on the graph.

If we form a line of best by joining any two points it can be seen that the rest of the points are close to this line but not very close.

Thus, implying that there is a moderately strong relationship between the two variables.

Thus, the statement accurately describing the data is:

Form: Linear Direction: Positive Strength: Moderate

Answer:

360 degrees

Step-by-step explanation:

Remember that triangles have a sum of 180 degrees, and that quadrilaterals have 360 degrees.

You can either use that part, or actually solve for it.

The equation for the sum of the interior angles is:

[tex]sum=180(n-2)[/tex]       [which "n" is the number of sides]

So, if we add in the number of sides to the equation, it changes to:

[tex]180(4-2)=180(2)[/tex], which equals to 360 degrees.

Answer:

[tex]2x + 15 = \frac{x}{2} - 3[/tex]

Move the variable

[tex]4x + 30 = x - 6[/tex]

[tex]4x - x + 30 = - 6[/tex]

Collect like terms

[tex]4x - x = - 6 - 30[/tex]

[tex]3x = - 6 - 30[/tex]

[tex]3x = - 36[/tex]

Divide both sides by three

[tex]x = - 12[/tex]
