the price of a ring was decreased by 25% to £390. what was the price before the decrease?

Using the concept of sample, the correct option is:

B. The sample is the randomly selected customers.

---------------------------

Sampling:  

Suppose I want to estimate the proportion of New York state residents who are Buffalo Bills fans. So i ask, lets say, 1000 randomly selected New York state residents whether they are Buffalo Bills fans, and expand this to the entire population of New York State residents.

In this case:

---------------------------

In this question, a survey is passed to the customers, which are the sample. Thus, the correct option is:

B. The sample is the randomly selected customers.

Answer:

Another ratio that is equivalent to this is 7:2.

Step-by-step explanation:

If we divide both sides by 6, we get 7 and we get 2. Since 42 comes first, we put the 7 in place of the 42. Then we replace 12 with 6. After this, we get the ratio 7:2.

Answer:

6x^2 + X -35

Step-by-step explanation:

Answer:

A=80

B=31

C=64

Step-by-step explanation:

A, 69, and b will equal 180 since it forms a straight line

A+69+b=180

to solve for A we subtract 53+47 from 180 and get 80

80+69+b=180

to get B we subtract 80+69 from 180 and get 31

to get c we add 85+b and subtract it from 180 getting c=64

Answer:

Hey it's me again the life saver ;)

To find b we can use the linear pair property but since only 1 angle is given, we owuld need at least 2 angles on this situation to find b so, to do that we are first going to find a

a=>

53 + 47 + a = 180

a=180 - 100

a=80°

Now to find b=>

80 + 69 + b =180 (Because of Linear pair property)

b = 180-149

b=31°

Now that we have got b, to solve c, we can again use the sum of all angles in a triangle are 180°

c=>

31 + 85 + c =180

c=180 - 116

c=64

An equation to arrive at the number will be:

This is because half the collection AFTER adding

(the other half was eaten by his dog).

Multiply both sides by

.

x

=

48

Subtract

from both sides.

x

Step-by-step explanation:

Solving; ( x + 3 ) ( x - 1 )

x ( x - 1 ) + 3 ( x - 1 )

x² - x + 3 ( x - 1 )

x² - x + 3x - 3

x² - 2x - 3

The coefficient of x in x² + 2x - 3 is 2

Answer:

(x + 9)(x + 2 )

Step-by-step explanation:

Sum =11

Product = 18

Factors = 9 , 2

When you multiply (9*2 = 18) and when you add (9 +2 = 11).

x² + 11x + 18 = x² + 9x + 2x + (9*2)

                   =x(x + 9) + 2(x + 9)

                  = (x + 9)(x + 2 )

Answer:

(x+9) (x+2)

Step-by-step explanation:

x^2+11x+18

x^2+9x+2x+18

x(x+9)+2(x+9)

Answer:

y coordinate = 13

x coordinate = -1

Step-by-step explanation:

Trail and error lol

The missing [x] - coordinate of point A is -2 and point B is -1.

The general equation of a straight line is -

[y] = [m]x + [c]

where -

[m] → is slope of line which tells the unit rate of change of [y] with respect to [x].

[c] → is the y - intercept i.e. the point where the graph cuts the [y] axis.

We have the equation of line as -

y = 3x + 7

Refer to the graph attached of the equation -

y = 3x + 7.

Since, the graph is not given we will mark two random points on it. It can be seen that the missing [x] - coordinate of point A is -2 and point B is -1.

Therefore, the missing [x] - coordinate of point A is -2 and point B is -1.
