A boat traveled 225 miles downstream and back. The trip downstream took 9 hours. The trip
back took 45 hours. Find the speed of the boat in still water and the speed of the current.

Answers

Answer:

30 hrs

Step-by-step explanation:

Downstream. In water, the direction along the stream is called downstream.

Upstream. In water, the direction against the stream is called upstream. Let the speed of a boat in still water be u km/hr and the speed of the stream be v km/hr, then. Speed downstream = (u + v) km/hr. Speed upstream = (u - v) km/hr

On a field trip, there are 3 chaperones for every 20 students. There are 92 people on the trip. Answer these questions. If you get stuck, consider using a tape diagram.

Answers

Answer:

I don't really know what the question is but..

Step-by-step explanation:

Since total of 92 people in the trip including student and chaperon, add groups of 23 to become 92 or use this equation

(20+3)xy=92

23y=92

y=92/23

y=4

therefore,

20x4=80 (students)

3x4=12 (chaperons)

Answer:

15 chaperones

Step-by-step explanation:

1. Okay, First you're going to see how many times 20 can feet into 92. Which is 4.5 times. However, you cannot cut someone in half. So the answer would actually be 5. Then. Just do 5*3, because remember, there are THREE chaperones for every 20 students.

Construct the indicated confidence interval for the difference between population proportions p1 - p2. Assume that the samples are independent and that they have been randomly selected. A marketing survey involves product recognition in New York and California. Of 558 New Yorkers surveyed, 193 knew the product while 196 out of 614 Californians knew the product. Construct a 99% confidence interval for the difference between the two population proportions.

Answers

Answer:

-0.0423≤p≤0.0977

Step-by-step explanation:

The margin error formula is expressed as;

ME = p±√p(1-p)/n

n is the sample size

For the first population proportion p1:

p1 = 193/558 = 0.3469

n1 = 558

p2 = 196/614 = 0.3192

n2 = 614

Taking the difference in the confidence of the proportion

p = p1-p2

p = 0.3469-0.3192

p= 0.0277

Get the margin of error

Margin of error = z*√p(1-p)/n

Margin of error = 2.5758*√0.35(1-0.35)/558 + 2.5758*√0.32(1-0.32)/614

Margin of error = 2.5758*√0.35(0.65)/558 + 2.5758*√0.32(0.68)/614

Margin of error = 2.5758*(0.02019)+2.5758(0.0188)

Margin of error = 0.07

Get the confidence interval

CI = p±ME

CI = (p-ME, p+ME)

CI = (0.0277-0.07, 0.277+0.07)

CI = (-0.0423, 0.0977)

Hence a 99% confidence interval for the difference between the two population proportions is -0.0423≤p≤0.0977

What is arithmetic?

In mathematics, it deals with a number of functions according to the statements.

here,
Let the cost of 1 orange = $x
The grocery store sells a bag of 7 oranges for $3.08.
So for 1 orange,
x = 3.08 / 7
x = $ 0.44

Thus, the required cost in dollars per orange is $0.44.

If the distance from St. Louis to Chicago is 297 miles, how much did Nimer's family's pay for the car rental?
Help this is my finals

Answers

Answer:

Nimer's family paid $489.25 for the car rental

Step-by-step explanation:

Nimer's family rents an SUV from a company that charges a flat rate of $19.99 plus $0.79 per mile driven.

They travel from St. Louis to Chicago and back. The distance between these cities is 297 miles, so they drive 2*297 = 594 miles.

The total charges include a flat fee of $19.99 and the cost of 594 miles:

$19.99 + $0.79 * 594 = $19.99 + $469.26 = $489.25

Nimer's family paid $489.25 for the car rental
