Answer:

25. rational

26. irrational

Step-by-step explanation:

A rational number is a number that can be written as a fraction. It may have decimals that end or repeating decimals.

An irrational number cannot be written as a fraction. It's decimals continue on and do not repeat.

25.

When you multiply two rational numbers, the product is rational. The square root of 16 is 4, which is rational because it is a whole number. 4/7 is written as a fraction so it is rational.

26.

The square root of 2 is an irrational number because its decimals go on and do not repeat. 7 is a whole number so it is rational. Subtracting a irrational number from a rational number gives an irrational number.

The following frequency table summarizes the number of children that dads in Dads Club have.

attashe74 [19]

Answer:

Step-by-step explanation:

Now there are 6+4+8+1+1=20 dads in the Dads Club.

Fewer than 3 children have

1 child - 6 dads
2 children - 4 dads.

So, 6+4=10 dads have fewer than 3 children.

The probability that the dad of Dads Club has fewer than 3 children is

$Pr=\dfrac{10}{20}=0.5 \text{ or } 50\%.$

The probability that the next dad to join Dads Club has fewer than 3 children is reasonable to be 50%.

What does the pair of equations y = 5, z = 6 represent? In other words, describe the set of points (x, y, z) such that y = 5 and

stiks02 [169]

Answer:

Option b.

Step-by-step explanation:

The set of points (x, y, z) such that y = 5 and z = 6.

So, all pairs are in the form of (x,5,6).

where, x can be any real number.

It the set of points (x,y,6), y and z-coordinates are constant.

So, the pair of equations y = 5, z = 6 represents a line parallel to x-axis and the distance of this line from xy-plane is 6 units and from xz plane is 5 units.

Therefore, the correct option is b.
