Brandi has equal numbers of hip-hop songs and country songs loaded on her personal music player. She has it set to play songs on

a random shuffle. Suppose Brandl is designing a simulation that could be used to estimate the probability that the next three songs to play are all hip-hop songs Which simulation design could Brandi use to estimate the probability?
A. Coin Let heads (H) = hip-hop Let tails (T) = country Toss coin three times. Repeat

B. Random digits Let 0.1phop Let 2.3.4.5.6 = country Select two random digits Repeat

C. Number cube Let 1 = hip-hop Let 2 = country Roll cube three times Repeat

D. Nurbe cube let 1 = hip-hop let 2 = country Roll cube four times. Report​

A certain number was multiplied by 7. 4 was taken away from the product. Finally, that difference was then divided by 9, resulti
marin [14]

Answer:

7

Step-by-step explanation:

To solve this, we have to work backwards. If you divide something by 9, and it equals 5, to figure out the number, we need to multiply by 9. 5*9= 45. If four was taken away, we have to add it to 45, which is 49. If a number *7 is 49, then we have to divide by 7 to get the answer. 49/7=7

When testing a claim that the majority of adult Americans are against the death penalty for a person convicted of murder, a rand
Black_prince [1.1K]

Using the z-distribution, it is found that the p-value is of 1.

At the null hypothesis, it is tested <u>that the majority is not against the death penalty</u>, that is:

H_0: p \neq 0.5

At the alternative hypothesis, it is <u>tested that the majority is against the death penalty</u>, that is:

H_1: p > 0.5

The test statistic is given by:

z = \frac{\overline{p} - p}{\sqrt{\frac{p(1-p)}{n}}}

In which:

  • \overline{p} is the sample proportion.
  • p is the proportion tested at the null hypothesis.
  • n is the sample size.

In this problem, the parameters are: \overline{p} = 0.27, p = 0.5, n = 491.

Then, the value of the <em>test statistic</em> is:

z = \frac{\overline{p} - p}{\sqrt{\frac{p(1-p)}{n}}}

z = \frac{0.27 - 0.5}{\sqrt{\frac{0.5(0.5)}{491}}}

z = -10.19

Using a z-distribution calculator, for a <u>right-tailed test</u>, as we are testing if the proportion is greater than a value, the p-value is of 1.

I’m trying to understand what it’s asking not sure if this is correct or not
Artemon [7]

Answer:

Step-by-step explanation:

First of all, the term multiple needs to be defined.

When a number is multiplied by another number other then zero, we get the multiple as result.

i.e. Multiples of 2 are: 2, 4, 6, 8, 10

To find the Least Common Multiple of numbers, we list the multiples of those numbers and then the samllest factor that is common in both lists is chosen as least common multiple.

1. 10, 20

Multiples of 10: 10, 20, 30, 40, 50, 60, 70, 80

Multiples of 20: 20, 40, 60, 80, 100

Least Common Multiple: 20

2. 3, 9

Multiples of 3: 3, 6, 9, 12, 15, 18, 21, 24, 27

Multiples of 9: 9, 18, 27, 36, 45

Least Common Multiple: 9

3. 12, 24

Multiples of 12: 12, 24, 36, 48, 60, 72

Multiples of 24: 24, 48, 72, 96

Least Common Multiple: 24

4. 25, 45

Multiples of 25: 25, 50, 75, 100, 125, 150, 175, 200, 225, 250

Multiples of 45: 45, 90, 135, 180, 225, 270, 315

Least Common Multiple: 225

5. 5, 10

Multiples of 5: 5, 10, 15, 20, 25, 30, 35, 40

Multiples of 10: 10, 20, 30, 40, 50, 60

Least Common Multiple: 10

6. 49, 56

Multiples of 49: 49, 98,147, 196, 245, 294, 343, 392, 441

Multiples of 56: 56, 112, 168, 224, 280, 336, 392, 448

Least Common Multiple: 392

This method of finding LCM is brute force and requires more time.

Another method is by using GCD(Greatest Common Divisor). It is the greatest positive integer number which completely divides all the numbers in consideration.

The product of the numbers is divided by their GCD to find the LCM.

i.e. for Q6

GCF(49, 56) = 7

LCM(49,56)=  (49*56)/7

=2744/7=392
