What is the least common multiple of 4 and 8

Ray Of Light [21]

Answer: 8

Step-by-step explanation: To find the least common multiple or (lcm) of 4 and 8, let's begin by listing the first few multiples of each number.

Multiples of 4

1 × 4 ≈ 4

2 × 4 ≈ 8

3 × 4 ≈ 12

4 × 4 ≈ 16

Notice that we skipped 0 × 6 in our list of multiples and this is because 0 × 4 is equal to 0 and our least common multiple can't be 0.

Now, let's list the multiples of 8. When listing the multiples of 8, it's a good idea to keep an eye on the list of multiples for 4 so that we will notice when we find a least common multiple.

Multiples for 8

1 × 8 = 8 ← is a multiple of 4

Notice that we can stop here because all other multiples that we find will be greater than 8. Therefore, the least common multiple or (lcm) of 4 and 8 is 8.

The American Academy of Periodontology released a survey, revealing that 27% of US adults admit they lie to their dentist about

AnnZ [28]

Answer:

Null Hypothesis, $H_0$ : p = 0.27

Alternate Hypothesis, $H_A$ : p > 0.27

Step-by-step explanation:

We are given that the American Academy of Period ontology released a survey, revealing that 27% of US adults admit they lie to their dentist about how often they floss their teeth.

Periodontist Dr. Garcia believes that the percentage seems low, so he decides to conduct his own hypothesis test to determine the true proportion.

Let p = % of US adults who admit they lie to their dentist about how often they floss their teeth

So, Null Hypothesis, $H_0$ : p = 0.27

Alternate Hypothesis, $H_A$ : p > 0.27

Here, null hypothesis states that the % of US adults who admit that they lie to their dentist about how often they floss their teeth is equal to 27%.

On the other hand, alternate hypothesis states that the % of US adults who admit that they lie to their dentist about how often they floss their teeth seems low and is more than 27%.

Also, the test statistics that would be used for conducting this hypothesis test will be One-sample z proportion statistics.
