The answer is B because 2 workdays of 8 hours equals 960 minutes. And a unit can travel 3.13 meters per minute because 3000 divided by 960 is 3.13

Answer:

Option B. 3.13 meters

Step-by-step explanation:

A refrigeration assembly line travels from start to finish = 3,000 meters.

It takes 2 days of 8 hour workdays for a single unit to go from start to finish.

2 days of 8 hour workdays = 8 × 2 = 16 hours

∵ 1 hour = 60 minutes

∴ 16 hours = 60 × 16 = 960 minutes.

Now we will divide total distance to 960 minutes.

The line move each minute = \frac{3000}{960}

                                              = 3.125 ≈  3.13 meters/ min.

The line moves 3.13 meters each minute.

Option B. 3.13 meters

Mark's dad is three times older than Mark. Mark's sister is 2 years younger than Mark. (3m) The sum of their ages is 48. How old
nataly862011 [7]

Answer:

Age of Mark =10 years

Age of Mark's dad =30 years

Age of Mark's sister =8 years

Step-by-step explanation:

Let age of Mark be x years.

Mark's dad is three times older than Mark

Age of her Mark's dad =3x

Mark's sister is 2 years younger than Mark

Age of Mark's sister =(x-2) years

The sum of their ages is 48.

x+3x+x-2=48\\5x-2=48\\5x=50\\x=10

Age of Mark =x=10 years

Age of Mark's dad =3x=3(10)=30 years

Age of Mark's sister =x-2=10-2=8 years

According to a study conducted by an​ organization, the proportion of americans who were afraid to fly in 2006 was 0. 10. A rand
algol13

According to the the concept of hypothesis testing, there is no evidence that the proportion of Americans who are afraid to fly has decreased.

Hypothesis testing:

Basically, in math hypothesis, it test the population on the basis of the sample data taken from the population using a simple random sampling.

Given,

According to a study conducted by an​ organization, the proportion of Americans who were afraid to fly in 2006 was 0. 10. A random sample of 1300  Americans results in 117 indicating that they are afraid to fly.

Now, we need to explain why this is not necessarily evidence that the proportion of Americans who are afraid to fly has.

While we looking into the given question,

Sample size, n = 1300

Number of Americans who were afraid to fly, x = 117

Now, we have to computing the sample proportion of Americans who afraid to fly,

Therefore, p = 117 / 1300 = 0.09

Then the Formulation of Hypotheses is written as,

Here the Null Hypothesis: H0: p≥0.10

And the alternative Hypothesis: Ha: p<0.10

Then the Left-tailed test of Test statistic is written as,

Here Let us assume that the level of significance, α = 0.05.

Then the Critical value, z≈−1.645

And the Decision rule is written as

If the value of  |z|<|z0.05|≈1.645: Do not reject the null hypothesis.

Otherwise If value of  |z|≥|z0.05|≈1.645: Reject the null hypothesis.
