6 0

Answer:

  no

Step-by-step explanation:

An arithmetic sequence has a common difference between adjacent terms. Here, the differences are ...

  • 9 -5  = 4
  • 15 -9 = 6

The differences are different, not common, so this is NOT an arithmetic sequence.

The angles of a triangle are in an extended ratio of 5:7:3. What is the measure of the
uranmaximum [27]

Answer:

84°

Step-by-step explanation:

Let the measures of the triangle be 5x, 7x, 3x.

By interior angle sum postulate of a triangle.

5x + 7x + 3x = 180°

15x = 180°

x = 180°/15

x = 12°

7x = 7*12°= 84°

Measure of the largest angle = 84°

The pie chart shows the results of 500 surveys asking students for their favorite movie genres. If you were creating a bar graph
andrew11 [14]

Pie charts are used to illustrate data in proportions and percentages

The height of the bar for "Drama" is 70

<h3>How to determine the height of the bar</h3>

The number of results is given as:

n = 500

The pie chart is not given.

So, we solve this question using an assumed value for the proportion (p) of "Drama" movie genre

Assume that the proportion is 14%, then the height of the bar would be:

Height= 14% * 500

Multiply

Height= 70

Hence, the height of the bar for "Drama" is 70

Suppose you just flipped a fair coin 8 times in a row and you got heads each time! What is the probability that the next coin fl
Svetllana [295]

Answer:

The probability is 1

Step-by-step explanation:

Given

Number of flips = 8

Outcomes = 8 heads

Required

Probability of getting a head in the next row

This problem can be attributed to experimental probability and it'll be solved using experimental probability formula, which goes as follows;

Probability = \frac{Number\ of\ Occurence}{Total\ Trials}

Let P(Head) represents the probability of getting a head in the next row;

P(Head)= \frac{Outcome\ of\ head}{Total\ Flips}

P(Head)= \frac{8}{8}

P(Head)= 1

Hence, the probability of obtaining a head in the next flip is 1
