Answer: See the table below (attached image)

  • Row 1:  2, 3, 5
  • Row 2: 6, 9, 15
  • Row 3: 8, 12, 20
  • Row 4: 12, 18, 30
  • Row 5: 14, 21, 35
  • Row 6: 16, 24, 40
  • Row 7: 20, 30, 50
  • Row 8: 28, 42, 70

Values in bold are the missing numbers to put into the boxes in the order shown.

====================================================

Explanation:

Each row is generated by using the original row 1. We can multiply every value in row 1 by the same positive whole number.

To get row 2, we multiply everything in row 1 by the value 3

  • We have 2 cups of red paint turn into 2*3 = 6 cups
  • Then we have 3 cups of yellow turn into 3*3 = 9 cups
  • Finally, 5 cups total turn into 5*3 = 15

So that explains why 9 and 15 go in the missing boxes for row 2. Note how 6+9 = 15. The first two columns always add to the third column value.

The other rows are generated in a similar fashion.

So we have...

  • For row 3, we multiply every value in row 1 by the number 4
  • For row 4, we multiply every value in row 1 by the number 6
  • For row 5, we multiply every value in row 1 by the number 7
  • For row 6, we multiply every value in row 1 by the number 8
  • For row 7, we multiply every value in row 1 by the number 10
  • For row 8, we multiply every value in row 1 by the number 14

If you're not sure what to multiply by, pick a value that's already given in the row in question, and divide it over its corresponding counterpart in row 1.

For instance, let's say we have no idea what to multiply by for row 8. We're given that 42 is in the middle of this row. Divide this over the corresponding middle value in row 1 to get 42/3 = 14. So 14 is our multiplier here. The same idea applies to any other row.

See the table below for the filled in values.

Consider the line y=5x -3 Find the equation of the line that is patellar to this line and passes through the point (-8, -3) Cons
Lynna [10]

Answer:

The equation of the line that is parallel to given line and passes through the point (-8, -3) is: y = 5x+37

Step-by-step explanation:

Given equation of line is:

y=5x-3

The general form of equation of line in slope-intercept form is written as:

y = mx+b

Here m(co-efficient of x) is the slope of the line and b is the y-intercept.

Comparing the given equation with the general form we get

m = 5

Two parallel lines have same slope so the slope of any line parallel to given line will also be 5.

Let m1 be the slope of required line parallel to y=5x-3

Then m1=5

Putting in general form

y = m_1x+b

y=5x+b

To find the value of b(y-intercept) the given point has to be put in the equation from which the line passes.

The point is (-8,-3)

-3 = 5(-8)+b\\-3 = -40+b\\b = -3+40\\b = 37

Putting the value of b and m1, we get

y = 5x+37

Hence,

The equation of the line that is parallel to given line and passes through the point (-8, -3) is: y = 5x+37

Assuming boys and girls are equally​ likely, find the probability of a couple having a baby girl when their sixth child is​ born
Ivanshal [37]

Answer:  The required probability of having 6th girl is 0.5.

Step-by-step explanation:  Given that boys and girls are equally likely.

We are to find the probability of a couple having a baby girl when their sixth child is​ born, given that the first five children were all girls.

Since the events of having a boy and a girl are independent of each other, so

the probability of having 6th girl dose not depend on the birth of the first five girls.

We know that there are only two possible cases (either a boy or girl will born).

So, sample space, S = {G, B}  and the event E of having a girl is, E = {G}.

That is, n(S) = 2 and n(E) = 1.

Therefore, the probability of event E is given by

P(E)=\dfrac{n(E)}{n(S)}=\dfrac{1}{2}=0.5.

Thus, the required probability of having 6th girl is 0.5.
