If a_n is a sequence that includes the terms:
250, ___, 10
What missing number(s) would the missing term be if:

a) a_n is arithmetic
b) a_n is geometric

Answers

Answer 1

9514 1404 393

Answer:

arithmetic: 130geometric: ±50

Step-by-step explanation:

Arithmetic sequence

The terms of an arithmetic sequence have common difference. If the missing term is x, then the difference between terms is the same:

  x -250 = 10 -x

  2x = 260 . . . . . . add 250+x to both sides

  x = 130 . . . . . . . . divide by 2

The missing term of an arithmetic sequence is 130.

(the common difference is -120)

__

Geometric sequence

The terms of a geometric sequence have a common ratio. If the missing term is x, then the ratios between terms are the same:

  x/250 = 10/x

  x^2 = 2500 . . . . . . . multiply both sides by 250x

  x = ±√2500 = ±50 . . . take the square root

The missing term of a geometric sequence is +50 or -50.

(the common ratio is ±1/5)

The line plot below shows the amount of water ( in gallons) students drank in a week. What is the difference in the lowest amount of water and the highest amount of water students drank

Answers

The difference in the lowest amount of water and the highest amount of water students drank is 1/2

How to determine the difference?

From the complete question (see attachment for line plot), we have:

Least = 1/8

Highest = 5/8

The difference is then calculated as:

Difference = Highest - Least

This gives

Difference = 5/8 - 1/8

Evaluate

Difference = 4/8

Simplify

Difference = 1/2

Hence, the difference in the lowest amount of water and the highest amount of water students drank is 1/2

Answers

I think the answer is E

The difference between the tallest and shortest player is 15 inches.

More than half of the players are 79 inches or taller.

The correct option is (C) and (E).

What is graph plotting?

A plot is a graphical technique for representing a data set, usually as a graph showing the relationship between two or more variables.

As we see the plot.

The tallest =84 inch and the shortest =69 inch

So, The difference between the tallest and shortest player is 15 inches.

7 players are in range of 68- 78

8 players are in range of 79-84

Thus,  More than half of the players are 79 inches or taller.

There are 20 sweets in a bag.
Seven of them are strawberry.
A sweet is taken at random from the bag.
What is the probability that the sweet taken is not strawberry?

Answers

7 of the sweets in the bag are strawberry. Since there are 20 sweets total in the bag, 20 - 7 = 13 sweets in the bag must be non-strawberry.

The probability that a sweet taken at random from the bag is not strawberry would thus be 13/20.

carpenter has a board that is 8 feet long. e cuts off two pieces. One piece is 32 feet ug and the other is 2 feet long. How ch of the board is left?​

Answers

Answer:

2 1/6 feet

Step-by-step explanation:

A carpenter has a board that is 8 feet long. He cuts off two pieces. One piece is 3 1/2 feet long and the other is 2 1/3 feet long. How much of the board is left?

Total length of the board = 8 feet

Piece A = 3 1/2 feet

Piece B = 2 1/3 feet

Piece A + piece B

= 3 1/2 feet + 2 1/3 feet

= 7/2 + 7/3

= (21+14) / 6

= 35/6

= 5 5/6 feet

Length of the board remaining = Total length of the board - length of the two pieces

= 8 feet - 35/6 feet

= (48-35) / 6

= 13/6 feet

= 2 1/6 feet

Length of the board remaining = 2 1/6 feet

In ΔPQR, the measure of ∠R=90°, the measure of ∠P=26°, and PQ = 8.5 feet. Find the length of QR to the nearest tenth of a foot.

Answers

Answer:

3.7feet

Step-by-step explanations

Using the sin rule

A/sin a = B/sin b

Let A = PQ = 8.5feet

B = QR = x feet

a = R = 90°

b = P = 26°

Substitute the values into the Sin rule

8.5/sin90 = x/sin26

8.5×sin 26 = x × sin 90

8.5×0.4383 = x× 1

3.7255 = x

Hence the length of QR to the nearest tenth 3.7feet
