Mathematics
1 answer:
baherus [9]3 years ago
4 0

Answer:

Ans. -8

Step-by-step explanation:

n = 4 for 4th term

B(4) = 1 (-2)^ 4-1 ( here B is 'a' ie. B4 is same as a4)

= 1 (-2) ^3 (2^3 is 8 , -2^3 is -8 )

= 1 (-8)

= -8

hence -8 is the fourth term in the sequence.

Name the set(s) of numbers to which 1.18 belongs.
FrozenT [24]

Answer:

Rational numbers

Step-by-step explanation:

Since 1.18 is a decimal number, it cannot belong to the set of integers or whole numbers.

However, also because it's a decimal number, it is rational because it can be written in the form p/q: 1.18=\frac{118}{100} .

Thus, 1.18 is only a rational number.

Hope this helps!

Consider a political discussion group of 8 democrats, 8 republicans and 6 independent suppose the teo groups meme bet are random
BartSMP [9]

Answer:

The probability of selecting two democrats is 1/380

Step-by-step explanation:

  • Probability is the branch of mathematics that deals with numerical descriptions of how likely an event is to occur.
  • Probability of an event = Number of favourable outcomes / Total number of outcomes.

Here we are given the people as,

8 democrats, 8 republicans and 6 independent.

So total number of people are: 8+6+6=20

Probability of choosing first democrat = 1/20

Probability of choosing first democrat = 1/19

Thus P( two democrats in succession ) = 1/20 ×1/19

                                                                = 1/380

The first floor of a house consists of a kitchen, playroom, and dining room. The areas of the kitchen, playroom, and dining room
lozanna [386]

Answer: See explanation

Step-by-step explanation:

From the question, we are informed that the areas of the kitchen, playroom, and dining room are in the ratio 4 : 3 : 2 and that the combined area of these three rooms is 189 square feet.

Therefore, Kitchen area = 4/(4+3+2) × 189 = 4/9 × 189 = 84 square feet

Playroom area = 3/(4+3+2) × 189 = 3/9 × 189 = 63 square feet

Dining room area = 2/(4+3+2) × 189 = 2/9 × 189 = 42 square feet
