What is Statistics?Statistics is the discipline that concerns the collection, organization, analysis, interpretation, and presentation of data.
To create a two-way table summarizing the data, we need to list the categories we are interested in and then fill in the counts for each combination of categories.
In this case, we are interested in the categories of swimming and canoeing, and we want to know how many students signed up for each combination of the two activities.
Canoeing No Canoeing
Swimming 28 43
Not swimming 34 45
Hence, the rows represent whether or not a student signed up for swimming, and the columns represent whether or not a student signed up for canoeing.

Answer:
the area of the porch is 5 times larger
Step-by-step explanation:
Area of a rectangle = length x width
Original area = 15 x 6 = 90 square feet
length of width after it was enlarged 5 times = 5 x 6 = 30
New Area = 30 x 15 = 450 square feet
change in area = 450 / 90 = 5

-5 = 1/7a
Answer:
-35
Step-by-step explanation:
[tex]-5 = \frac{1}{7}a\\-35 = a[/tex]
I got this by multiplying the numerator by 7. This allows the denominator to be the same as the numerator, thus equalling 1.
1 * a = a
Answer: a = -35
Step-by-step explanation:
1. -5 = 1/7(a) || GIVEN
2. -5 * (7) = (7) * 1/7(a) || Isolate "a" on one side of the equation by multiplying 7 to the other side.
3. -35 = a

Answer:
250 gallons of water are being pumped out each hour
Step-by-step explanation:
It tells us that W is the amount of water in the pool at a time. It also tells us that at the start there is 9000 gallons in the pool. We also know t is the time in hours so 1 t = 1 hour.
W=9000-250t
We can substitute in what we know
The amount of water in the pool = 9000 gallons - 250 gallons times 1 hour
so that means if one hour passes 250 gallons are removed, and if 2 pass then 500 are removed showing that for every hour the pump is on 250 gallons of water are being sucked from the pool

A store has clearance items that have been marked down by 55%. They are having a sale advertising an additional 25% off clearance items. What % of the original price do you end up paying
Answer: 33.75%
Step-by-step explanation:
The items were marked down by 55% from their original price.
This means that the new price is:
= 1 - Percentage marked down
= 1 - 55%
= 45% of the original.
From this 45%, additional percentage of 25% is removed from this amount. The amount left will be:
= 45% * ( 1 - 25%)
= 33.75%

The manufacturer of a certain brand of aluminum foil claims that the amount of foil on each roll follows a Normal distribution with a mean of 250 ft2 and a standard deviation of 2 ft2. To test this claim, a restaurant randomly selects 10 rolls of this aluminum foil and carefully measures the mean area to be ¯ = 249.6 ft2
Find the probability that the sample mean area is 249.6 ft2 or less if the manufacturer’s claim is true
Answer:
Given that the manufacturers claim is true, the probability that the sample mean area is 249.6 ft.² or less is 0.42074
Step-by-step explanation:
The manufacturer claims that mean amount of foil on each roll, μ = 250 ft²
The standard deviation of the measured amount of foil per roll, σ = 2 ft.²
The number of rolls tested by the restaurant, n = 10 rolls
The mean measured by the restaurant, [tex]\overline x[/tex] = 249.6
Taking the sample means as individual score, we have;
The z-score, of the sample mean is given as follows;
[tex]z=\dfrac{\overline x -\mu }{\sigma }[/tex]
At [tex]\overline x[/tex] = 249.6, we have;
z = (249.6 - 250)/2 = -0.2
Therefore, the probability for a mean less than or equal to 249.6, we have;
The probability, P = P(z < -0.2) = 0.42074
The probability that the sample mean area is 249.6 ft.² or less given that the manufacturers claim is true, P = 0.42074.

Step-by-step explanation:
A salesperson is selling cooking sets for $120 each. The salesperson receives 22.5% of the sales prices as commission. The salesperson sells a total of 4 units on Monday but an unknown number of units on Tuesday. The salesperson made a combined total of $351 commission for those two days. Write an equation that could be used to find the number of cooking sets x sold on Tuesday. Then solve the equation.
[Please help!]
Answer:
4(120)(.225) + x (120)(.225) = $351
9 units sold on Tuesday
Step-by-step explanation:
1. You can easily figure how much money was made on Monday by multiply the total units sold by the price per unit by the commission in decimal form. Here you get $108.
2. Subtract that $108 from the $351 made on both days and you get $243 made on Tuesday.
3. The equation is now the unknown number of units sold (x) times the price ($120) times the commission is decimal form (.225) equals $243.
4. Since 120 times .225 is equal to 27, the equation now becomes 9x is equal to 243.
5. Divide 243 by 27 for your answer.
