Find the value of 18 ÷ 9 ∙ 3

Answers

Answer 1
Answer:

The value of mathematical expression by using PEMDAS rule is 6.

What is PEMDAS ?

A rule of operations explains the correct order in which math expressions should be evaluated, and we can remember those steps using PEMDAS: Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right).

Here, the mathematical expression is given as 18 ÷ 9 ∙ 3, no solving it by using the PEMDAS rule which tells us to first divide 18 by 9 and then multiply by 3.

18/9 x 3 = 2 x 3 = 6.

Therefore, the value of mathematical expression by using PEMDAS rule is 6.

Answer:

Cluster sampling

Step-by-step explanation:

AI-generated answer

The sampling method described in the question is cluster sampling. In cluster sampling, the population is divided into clusters or groups, and then a random sample of clusters is selected. In this case, the blocks in the neighborhood are the clusters.

Here is a step-by-step explanation of why this is cluster sampling:

1. The first step is to divide the population into clusters. In this case, the population is the neighborhood, and the clusters are the different blocks within the neighborhood.

2. Next, a random sample of clusters is selected. The question states that 10 different blocks in the neighborhood are chosen. This means that the researchers randomly selected 10 blocks from the neighborhood.

3. Once the clusters are selected, a sample is taken from each cluster. The question states that on these 10 blocks, 10 houses are selected at random. This means that within each of the 10 selected blocks, 10 houses are chosen randomly.

4. Finally, the residents of each selected house are interviewed. This means that every resident of each of the selected houses is interviewed to gather information about the type of phone service they prefer.

Overall, this sampling method is cluster sampling because the population is divided into clusters (blocks), a random sample of clusters (10 blocks) is selected, and then a sample is taken from each selected cluster (10 houses on each block).

The diameter of a bicycle wheel is 2 feet.About how many revolutions does the wheel make to travel 2 kilometers?Explain.Hint 1 km =3280ft.

Answers

We can work out the circumference of the wheel by using the equation

C = πd

C = π × 2
C = 6.28318530718
C = 6 feet

If 1km is 3280 feet, 2km is 6560 feet

6560 ÷ 6 = 1093.33333333 (recurring)
= 1093

Therefore the bike wheels rolls (approximately) 1093 times to cover 2km.

If the probability of success during a single event of a geometric experiment is 0.16, what is the probability of success by the 8th event? Round your answer to the nearest tenth of a percent.

Answers

The probability of success by the 8th event is 75.21%.

Probability of success: 0.16
Probability of failure:
        = 1 - P (Prob. of success)
        = 1 - 0.16
        = 0.84
Total probability of failure:
        = 0.84 ^ 8 (# of event)
        = 0.247875891

Probability of success on the 8th event:
        = 1 - Probability of failure on previous events
        = 1 - 0.247875891
        = 0.7521 or 75.21% 

To get either probability, deduct the given from 1 which serves as the 100% probability.
