Answer:

The coefficients are:

[tex](a)\ 5x[/tex]

[tex](b)\ -4b[/tex]

[tex](c)\ 38bc[/tex]

[tex](d)\ -24b^2c[/tex]

Step-by-step explanation:

Required

The coefficient of a

To get the coefficient, we simply remove a. The remaining terms is the required coefficient

Solving (a):

[tex]Expression = 5ax[/tex]

Remove a

5x:

Hence, the coefficient is 5x

Solving (b):

[tex]Expression = -4ab[/tex]

Remove a

-4b

Hence, the coefficient is -4b

Solving (c):

[tex]Expression = 38abc[/tex]

Remove a

38bc

Hence, the coefficient is 38bc

Solving (d):

[tex]Expression=-24ab^2c[/tex]

Remove a

[tex]-24b^2c[/tex]

Hence, the coefficient is [tex]-24b^2c[/tex]

Answer:

Step-by-step explanation:

Note that the two equations are equivalent.

2y = 14-2x can be rearranged to y = -x+7, which is the same as the second equation. What you're looking is one line on top of the other.

Every shared point is a solution. Since there are infinitely many points on a line, and these lines share every point, there are infinitely many solutions.

Answer:

x<2

Step-by-step explanation:

Hello There!

Our objective for this problem is to isolate the variables

To do so we use inverse operations

x+4<6

subtract 4 from each side

4-4 cancels out

6-4=2

we're left with

x<2

Step-by-step explanation:

It is just like a normal x equation just with an inequality. So for now, just represent the < as and =

so we have x+4=6

subtract 4 from both sides

x+4-4=6-4

x=2

Now we insert the <

x<6

so all values for x are all less than 6

Hope that helps :)

Answer:

a) x = 1.52

b) s = 1.16

Step-by-step explanation:

We have that:

5 students watched 0 movies.

9 students watched 1 movie.

5 students watched 2 movies.

5 students watched 3 movies.

1 student watched 4 movies.

(a) Find the sample mean x.

Sum divided by the number of students. So

[tex]x = \frac{5*0 + 9*1 + 5*2 + 5*3 + 1*4}{5 + 9 + 5 + 5 + 1} = \frac{38}{25} = 1.52[/tex]

(b) Find the approximate sample standard deviation, s.

Standard deviation of the sample.

Square root of the sum of the squares of the values subtracted from the mean, divided by the sample size subtracted by 1. So

[tex]s = \sqrt{\frac{5*(0-1.52)^2 + 9*(1-1.52)^2 + 5*(2-1.52)^2 + 5*(3-1.52)^2 + 1*(4-1.52)^2}{24}} = \sqrt{\frac{32.24}{24}} = 1.16[/tex]

Answer:

Step-by-step explanation:

1). System of equations is,

  -2x - y = -22 -------(1)

   4x - 8y = 4 -------(2)

   By satisfying these equations with the given point (9, 4),

  Equation (1)

  -2(9) - 4 = -22

  -18 - 4 = -22

  -22 = -22

  True.

  Equation (2)

  4(9) - 8(4) = 4

  36 - 32 = 4

  4 = 4

  True.

  Given point lies on both the equations.

  Therefore, the given point is the solution of the system of equations.

2). 3x - 3y = 27 -----(1)

  -2x + 9y = -11 ------(2)

  Satisfy the equations with the given point (-10, -1)

  Equation (1)

  3(-10) - 3(-1) = 27

  -30 + 3 = 27

   -27 = 27

   False.

  Equation (2)

  -2x + 9y = -11

  -2(-10) + 9(-1) = -11

   20 - 9 = -11

   11 = -11

   False.

  Therefore, the given point is not the solution of the system of equations given.

Answer:

the principal balance at the beginning of June is $22,222.22

Step-by-step explanation:

The computation of the principal balance at the beginning of June is shown below:

Principal balance = Interest paid ÷ (Interest Rate ÷ 12 Months)

= $250 ÷ (13.5% ÷ 12)

= $22,222.22

Hence, the principal balance at the beginning of June is $22,222.22

Answer:

I don't understand what the problem is saying... 2124...95...

Step-by-step explanation:

Answer:

a) V = 35.1 in.^3

b) V = 288 pi in.^3

c) h = 2.7 in.

Step-by-step explanation:

a)

radius of base = 2 in.

height = 8 in.

volume of cone = (1/3)(pi)(r^2)h

V = (1/3)(pi)(2 in.)^2(8 in.)

V = 35.1 in.^3

You are correct.

b)

You must leave the answer in terms of pi, so do not use 3.14 or another approximation for pi.

radius of base = 6 in.

height = 24 in.

volume of cylinder = (pi)(r^2)h

V = (1/3)(pi)(6 in.)^2(24 in.)

V = 288 pi in.^3

c)

volume = 288 pi in.^3

radius = 18 in.

288 pi in.^3 = (1/3)(pi)(18 in)^2 h

288 in. = (1/3)(324)h

288 in. = 108h

h = 2.666 in.

h = 2.7 in.

Answer:

70

Step-by-step explanation:

Hello There!

So if you didn't know an exterior angle of a triangle is equal to the two opposite interior angles of a triangle

So basically

∠XYZ=∠WXY+∠XWY

so to find ∠XWY we subtract the value of ∠WXY (45) from the value of the exterior angle (115)

115-45=70 so ∠XWY=70

Answer:

?+45=115° sum of two interior angle of the triangle is equal to the exterior angle

<XWY=115-45=70

Step-by-step explanation:

One interior angle of a triangle = 30⁰ .

The measure of other two are x and y .

We know that the angle sum property of a triangle is 180⁰ .

=> x + y + 30⁰ = 180⁰

=> x + y = 180⁰ - 30⁰.

=> x + y = 150⁰.

Possible solution set of x and y are ,

(1,149) (2,148 ) ...... (148+2) & (149+1)

Basically we are here decreasing y and increasing x to obtain the values .

Hope it helped !

Answer:

120 - 14 = 106

Step-by-step explanation:

7 x 2 = 14

10 x 12 = 120 therefore you,

120 - 14 = 106

The area of the shaded region is 106 m².

We have,

The area of the rectangle:

= length x width

From  the figure,

Bigger rectangle dimensions:

Length = 12 m

Width = 10 m

Smaller rectangle dimensions:

Length = 7 m

Width = 2 m

Now,

The shaded region.

= Area of the bigger rectangle - Area of the smaller rectangle

= 12 x 10 - 7 x 2

= 120 - 14

= 106

Thus,

The area of the shaded region is 106 m².
