A train company moves people between Boston and Providence every day. They travel from city to city 7 times each day. The distance between the two cities is 48 miles. In​ February, there are 28 days. The​ company's budget allows for​ 15,000 total miles in February. Do you think the budget is​ reasonable? Explain.

Answers

Answer: the budget is reasonable since the calculated distance travelled hasn’t exceeded the budget

Step-by-step explanation:

Given data:

Distance between two cities = 48 miles

Number of days available in February = 28

February budget = 15000 miles

Solution:

If the distance between two cities = 48 miles, and 7 trips are made daily

= 48miles * 7

= 336 miles is travelled each day.

For February

= 28days * 336

= 9408 miles.

Budget – travel distance covered ( February)

= 15,000 - 9408

= 5592 miles.

The budget is reasonable because, by following the travel pattern or history the total travelled miles would be 9408 miles for February which is below the budget allowed by the company for the month.

So the budget is reasonable since the calculated distance travelled hasn’t exceeded the budget.

Jade takes 5 minutes more than twice as long as Binh to ride to their friend’s house. If Binh takes x minutes to ride to his friend’s house, how long will it take Jade?

Answers

Answer:

It will take Jade (2x + 5) minutes

Step-by-step explanation:

Let us find the expression that represents the time Jade will take

∵ Binh takes x minutes to ride to his friend’s house

∴ The time Binh takes = x minutes

∵ 5 more means + 5

∵ Twice means × 2

∵ Jade takes 5 minutes more than twice as long as Binh to ride to their

   friend’s house

→ Multiply the time Binh takes by 2 and add the product by 5

∵ Binh takes x minutes

∴ The time Jade takes = 2 × x + 5

∴ The time Jade takes = 2x + 5 minutes

∴ It will take Jade (2x + 5) minutes

Find the mean, variance and standard deviation of the binomial experiment. In a recent survey, 70% of the community favored building a police substation in their neighborhood. If 30 citizens are chosen, what is the mean number favoring the substation? What would be the variance and standard deviation of their responses?

Answers

Answer: Mean = 21 , Variance = 6.3 , standard deviation =2.51

Step-by-step explanation:

Formula for the mean, variance and standard deviation of the binomial experiment :

[tex]Mean = np\\\\ Variance = np(1-p)\\\\ Standard\ deviation = \sqrt{variance}[/tex]

, where n= sample size , p= population proportion.

As per given, p= 70%=0.7 , n=30

[tex]Mean = 0.7\times30=21\\\\Variance =(30)(0.7)(1-0.7)=(21)(0.30)=6.3\\\\ Standard\ deviation = \sqrt{6.3}\approx2.51[/tex]

Hence, Mean = 21 , Variance = 6.3 , standard deviation =2.51

Connor says that the graph shows that water is flowing at a rate of 2 gallons per minute. Is he correct?

a. Connor is correct because the rate of water flowing is equal to the slope. Water is flowing in at a rate which is about 2 gallons per minute.

b. Connor is not correct because the rate of water flowing is greater than the slope. Water is flowing in at a rate which is slower than 2 gallons per minute.

c. Connor is not correct because the rate of water flowing is not equal to the slope. Water is flowing in at a rate which is slower than 2 gallons per minute.

d. Connor is correct because the rate of water flowing is less than the slope. Water is flowing in at a rate which is faster than 2 gallons per minute.

Answers

Answer:

Part A: ½

Part B: c. Connor is not correct because the rate of water flowing is not equal to the slope. Water is flowing in at a rate which is slower than 2 gallons per minute.

Step-by-step explanation:

Part A:

Slope of the proportional graph = y/x

Using the point on the line, (4, 2),

Slope = 2/4 = ½.

Part B:

Since the slope of the graph bus ½, it shows that the water is flowing at a rate of ½ gallon per minute. Therefore, Connor is NOT CORRECT.

The rate of water Connor stated does not correspond with the rate shown by the slope. The slope of the graph, ½, shows that the water is flowing at a much slower rate than at the rate of 2 gallons per minute, which Connor stated.

The right answer is C.
