Answer:

f^-1(x)=1/2x-3/2

Step-by-step explanation:

f(x)=2x+3

y=2x+3

x=2y+3

2y+3=x

2y=x-3

y=1/2x-3/2

substitute f^-1(x) for y

f^-1(x)=1/2x-3/2

Answer:

The three numbers are : 9, 9 and 18

Step-by-step explanation:

Since the mean is 12 the sum of the three numbers must be 36. This is because:

(let the three numbers be x y and z)

(x+y+z)/3=12

(x+y+z)=12*3

(x+y+z)=36

And since the mode is 9 two of the numbers must be 9.

So to find the third number;

9+9+z=36

z=36-18

z=18

Answer:

77 boxes

Step-by-step explanation

Hello there! Let's solve this problem together:

First, we will review our numbers.

13 girls have to sell 1,000 boxes.

Now, we will do the math.

We will solve this problem by dividing.

We will keep multiply by one until we reach 1000 or more.

They have to each sell at least 77 boxes.

Answer:

Area of Triangle QRP = 3[tex]\sqrt{3}[/tex]

Step-by-step explanation:

According to Question , We have a circle With Centre 'O' & Area 48[tex]\pi[/tex] .

Area Of Circle = 48[tex]\pi[/tex]

[tex]\pi[/tex][tex]r^{2}[/tex] = 48[tex]\pi[/tex]

r = [tex]\sqrt{48}[/tex]

Now We Have Two Points Given On Circle Q & R , P Is Circumcentre Of Triangle QRO .

Thus A Circle Can Also Be Formed with Centre P . ( See attachment For Diagram )

Now The Diameter of Circle With Centre P = Radius Of Circle with Centre O

so Radius Of Circle With Centre P([tex]r_{2}[/tex]) = [tex]\frac{\sqrt{48}}{2}[/tex]

Now We Have To Find Area Of Equilateral Triangle .

A = [tex]\frac{\sqrt{3}}{4} r_{2} ^{2}[/tex]

A= [tex]\frac{\sqrt{3} }{4} * \frac{\sqrt{48} }{2}*\frac{\sqrt{48} }{2}[/tex]

The Area Of PQR is = 3[tex]\sqrt{3}[/tex]

Answer:

  y = x² +x -6

Step-by-step explanation:

The graph shows the zeros of the function to be -3 and +2. This means the factored form of the function can be written as ...

  y = (x -(-3))(x -(+2)) = (x+3)(x-2)

Multiplying this out, we get the desired standard form:

  y = x² +x -6

We note that y=-6 when x=0, which matches the y-intercept. Nothing else needs to be done to this equation.

Answer:

Independent variable or explanatory variables.

Step-by-step explanation:

this variable is referred to as the independent variable.

A linear regression equation is of the form

Y = B0 + B1X1 + u

Y is the depndent variable

X1 is the independent variable

With u as the error term.

The independent variable is used to explain changes in Y, which is the dependent variable. The independent or explanatory variable has a direct effect on the dependent variable. This means that as X1 changes, Y would also change in response to the changes in the independent variable.

Answer:

Step-by-step explanation:

C

Answer:

the possible values of c = -23,  -10,  -5,  or -2

Step-by-step explanation:

The possible values of c that will allow the polynomial to be factored must be a factor of "-24"

1 x (-24) = -24    (for this case c = -23)

2 x (-12) = -24    (for this case c = -10)

3 x (-8) = -24     (for this case c = -5)

4 x (-6) = -24     (for this case c = -2)

Therefore, the possible values of c = -23,  -10,  -5,  or -2

Answer:

b=1/2

Step-by-step explanation:

2logb - 3logb = log8b - log4b

log[tex]b^{2}[/tex] - log[tex]b^{3}[/tex] = log8b - log4b

log([tex]\frac{1}{b}[/tex]) = log(2)

∴1/b = 2

∴b = 1/2

Answer:

28 biscuits

18 packages of pemmicans

4 packages of butter and cocoa

Step-by-step explanation:

We are given percentage of total daily calories for each item.

Since total number of calories per person each day is 5600,then;

Number of calories from biscuit daily = 40% × 5600 = 2240 calories

Since there are 80 calories per biscuits, then number of biscuits = 2240/80 = 28 biscuits

Number of calories from pemmican daily = 45% × 5600 = 2520 calories

Since there are 140 calories per package, then number of packages of pemmican = 2520/140 = 18 packages of pemmicans

Number of calories from butter and cocoa daily = 15% × 5600 = 840

Since there are 210 calories per package, then number of packages = 840/210 = 4 packages of butter and cocoa

Answer:

The probability that you will have a white chip is 0.309

Step-by-step explanation:

You on the first try have a 1/7 or 14.285% chance the second one has a 1/6 or a 16.666% you then add them together and you have a 30.9% chance

The Probability of selecting white chips is [tex]0.0286[/tex].

Let,

The probability of the poker chips is,

            [tex]\ n(A)=3\\\\n(B)=3\\\\n(C)=1[/tex]

Lets find the the probability of selecting white clip:

"Probability [tex]=[/tex] Number  of outcomes/ Total outcomes"

Randomly select two chips from the jar,

                            [tex]P(C)=\frac{n(c)}{n(s)} \\\\P(C)=\frac{1}{7}[/tex]

          If the first chip is not white then the probability of the second chip being white is,

                     [tex]P(no\ white)=\frac{1}{6}[/tex]

                            [tex]\frac{1}{6} * \frac{1}{7} = \frac{1}{7}[/tex]

Total probability is the sum of the two probability is,

                            [tex]P=\frac{1}{7} +\frac{1}{7} \\\\P=\frac{2}{7}=0.286[/tex]

Hence,

The Probability of selecting white chips is [tex]0.0286[/tex].
