Michael uses lemonade concentrate and water to make lemonade for the family. The ratio of cups of lemonade
concentrate to cups of water is 1:3. If he made 32 cups of lemonade for the family, how many cups of
concentrate did he need?

Answers

Answer:

8 cups

Step-by-step explanation:

Given that the ratio is 1:3

concentrate =1

water=3

the total =3+1=4

using the part to all method

1/4=x/32

cross multiply

4x=32

divide both sides by 4 we have

x=32/4

x=8

Therefore the amount of concentrate is 8 cups

Answers

Answer: 35.522

Step-by-step explanation:

Answer:

35.5225

Step-by-step explanation:

4/142.09

look at each place starting in the hundredth place

how many times does 4 go into 14, 3 times

subtract the 12 from th 14 and you get a remainder of 2

drag the 2 down and you get 22

4 goes into 22 5 times

22-20=2

so on and so on

4/142.09

14-12=22 (3 times)

22-20=2 (5 times)

20-20=0 (5 times)

09-8=1 (2 times)

10-8=2 (2 times)

20-20=0 (5 times)

The EPA wants to know the daily level of pollutant discharge in the manufacturing district in Pittsburgh for February 2005. The monitoring equipment reveals that the mean daily discharge per factory (calculated as total areal discharge divided by total areal factories) is 30.2 tons with a standard deviation of 9.1 tons. Construct a confidence interval for the true population mean of pollutant discharge using a 95% level of confidence.

Answers

Answer:

The 95% confidence interval for the true population mean of pollutant discharge is (26.7 tons, 33.7 tons).

Step-by-step explanation:

Let X represent the daily level of pollutant discharge in the manufacturing district in Pittsburgh.

The monitoring equipment reveals that for the 28 days of the February month

Mean daily discharge per factory, ([tex]\bar x[/tex]) = 30.2 tons

Standard deviation daily discharge per factory, (s) = 9.1 tons

Compute the critical value of t for 95% level of confidence and (n - 1 =) 27 degrees of freedom as follows:

[tex]t_{0.05/2, 27}=2.052[/tex]

*Use a t-table.

Compute the 95% confidence interval for the true population mean of pollutant discharge as follows:

[tex]CI=\bar x\pm t_{\alpha/2, (n-1)}\cdot\frac{s}{\sqrt{n}}[/tex]

     [tex]=30.2\pm 2.052\times\frac{9.1}{\sqrt{28}}\\\\=30.2\pm 3.53\\\\=(26.67, 33.73)\\\\\approx (26.7, 33.7)[/tex]

Thus, the 95% confidence interval for the true population mean of pollutant discharge is (26.7 tons, 33.7 tons).

To gather data for a statistics project, a student asked 10 friends how many hours of sleep they got on the previous night. The data are shown in the following list.

Answers

Answer:

3

Step-by-step explanation:

INTERQUARTILE RANGE (IQR) = Q3 - Q1

Rearranging the data: 3, 4, 5, 5, 6, 7, 7, 8, 9, 9

Q3 = 0.75(n+1)th term

Q3 = 0.75(10 + 1) th term

Q3 = 0.75(11)th term = 8.25th term

Taking the 8th term = 8

Q1 = 0.25(11)th term = 2.75th

Taking the average of the 8th and 9th term:

(5 + 5) / 2 = 10/2 = 5

Q3 - Q1 = (8 - 5) = 3

3. In the month of August, a car dealership sold a total of 72
cars and trucks. The dealership reported that for every 4
passenger cars sold, there were 2 trucks sold. How many of
each type of vehicle were sold in the month of August?

Answers

Answer:

The dealership sold in August 24 trucks and 48 cars

Step-by-step explanation:

Equations

A dealership reported they sold a total of 72 vehicles.

It also determined that for every 4 cars sold, they sold 2 trucks. It means that they sold twice as many cars as trucks.

Let x be the number of trucks sold.

It follows that 2x is the number of cars sold.

The sum of both numbers must equal 72:

x + 2x = 72

Simplifying:

3x = 72

Solving:

x = 72 / 3 = 24

The number of cars were

2x= 48

The dealership sold in August 24 trucks and 48 cars
