When Betsy Ross sewed the first American flag, the flag had an area of 27 square feet. If the base of the flag was 9 feet, what was the height of the flag?
Answer:
The height of the flag was 3 feet.
Step-by-step explanation:
To solve this problem, we must first recall the formula for area of a rectangle to be:
Area = base * height
Next, we can substitute in the values that we were given in the problem. We were told that the area was 27 square feet and the base was 9 feet.
27 = 9 * height
Now we can treat this equation that we have created similar to any other equation we would like to solve. We must solve for the unknown, or the variable, which in this case is the height. To do this, we should divide both sides by 9 to get the "height" variable by itself on the right side of the equation. This is modeled below:
27/9 = (9 * height)/9
3 = height
Therefore, the height of the flag was 3 feet.
Hope this helps!
Answer:
The height is 3,
Step-by-step explanation:
First up, if we know the B in the B*H=A formula, we can divide the area by the base (27/9) and get the height, 3.
I too am learning this. The thing is you want to do a reverse order. For example, 2*3=6; so automatically we would know that 6/3=2.

ON, R(natural, real numbers
O Q(rational numbers)
Q, R (rational, real numbers)
O W, R (whole, real numbers)
The correct answer is C. Q, R (rational, real numbers)
Explanation:
The number [tex]\frac{25}{11}[/tex] is a fraction, which means it represents proportions of a whole. This number can be classified as rational, which is represented by the letter Q because this category of numbers includes those numbers that can be represented as a fraction and the number provided is naturally a fraction. Moreover, this number is also a real number, which is a broad category of numbers represented by the letter R that includes rational numbers such as fractions. This means this number is rational and because of this, it is also real.
On the other hand, this number is not natural because this includes regular numbers such as 3, 43, or 3947 but not fractions, and it is not a whole number because a fraction does not represent a whole number but just a proportion.

A 12 foot board is cut so that one piece is 5 times as long as the other. Find the length of each piece.
Answer:
2 and 10
Step-by-step explanation:
Let x be length of the small piece and y the length of the big one.
● y = 5x
Since the big piece is 5 times longer than the short one.
The total length is 12 ft
● y + x = 12
● 5x + x = 12
● 6x = 12
Divide both sides by 6
● 6x/6 = 12/6
● x = 2
So the length of the two pieces are 2 ft and 10 ft (5×2)
The length of each piece is 2 units and 10 units.
How to know how many times a number is to another ?To know how times a number is to another just divide the larger number to the smaller number.
According to the given question a 12 foot board is cut so that one piece is 5 times as long as the other.
Assuming one piece to be x and the other to be 5x.
∴ x + 5x = 12
6x = 12
x = 2.
So, one piece is of 2 units and other piece is of 5(2) = 10 units.
To confirm that one piece is of 5 times of the other we divide the larger piece by the smaller piece which is 10/2 = 5.

In 2007, the first generation of the i-phone sold for $499. The average cost of an i-phone today is $999. At a press conference just outside a telephone museum in Cle Elum, WA, the CEO of Apple, Tim Cook, stated that the rise in cost is purely due to inflation. Use the Consumer Price Index to either verify or falsify Cooks’s statement. Is he wrong?
Answer: the statement made by Tim Cook is TRUE
Step-by-step explanation:
Given that;
in 2007 cost of 1st gen iphone = $499 (base year price)
cost of iphone today = $999 (current year price)
Using the Consumer Price Index
the Consumer Price Index = (cost pf product in current years/cost of product base year) × 100
we substitute
CPI = (999/499) × 100
CPI = 200.2004
so the CPI is 100.2004% higher in the current year than in the base year
Checking the inflation rate
IR = (( CPI this year- CPI last year)/CPI last year) × 100
CPI last year (base year) = 100
CPI current year is = 100.2004
so
IR = (( 100.2004 - 100)/100) × 100
IR = 0.002004 × 100
IR = 0.2004%
THEREFORE the statement made by Tim Cook is TRUE

Answer: Median Mode Mean
Step-by-step explanation:
A normal distribution a symmetric distribution where most of the values lies around the central peak where Mean, median mode all lies together and the value of z=0 (as z-value given the distance of data values from mean with respect to the standard deviation).

4) Martin compares the prices of paper towels. A 3-roll package is priced at $2.89. A single
rollis priced at $89. Based on price alone, which is the better buy?
Answer:
assuming prices are correctly shown: 3-roll packageassuming a typo: single rolls.Step-by-step explanation:
If single rolls are indeed priced at $89 each, the 3-roll package is a much better buy.
We suspect that the single rolls are priced at $0.89 each, which means you can buy 3 of them for less than $2.70. At this price, single rolls are a better buy.

Find a formula for the sum of n terms. Use the formula to find the limit as n → [infinity]. lim n → [infinity] n 2 + i n 8 n i = 1
Complete Question
Find a formula for the sum of n terms. [tex]\sum\limits_{i=1}^n ( 8 + \frac{i}{n} )(\frac{2}{n} )[/tex]
Use the formula to find the limit as [tex]n \to \infty[/tex]
Answer:
[tex]K_n = \frac{n + 73 }{n}[/tex]
[tex]\lim_{n \to \infty} K_n = 1[/tex]
Step-by-step explanation:
So let assume that
[tex]K_n = \sum\limits_{i=1}^n ( 8 + \frac{i}{n} )(\frac{2}{n} )[/tex]
=> [tex]K_n = \sum\limits_{i=1}^n ( \frac{16}{n} + \frac{2i}{n^2} )[/tex]
=> [tex]K_n = \frac{2}{n} \sum\limits_{i=1}^n (8) + \frac{2}{n^2} \sum\limits_{i=1}^n(i)[/tex]
Generally
[tex]\sum\limits_{i=1}^n (k) = \frac{1}{2} n (n + 1)[/tex]
So
[tex]\sum\limits_{i=1}^n (8) = \frac{1}{2} * 8* (8 + 1)[/tex]
[tex]\sum\limits_{i=1}^n (8) = 36[/tex]
[tex]K_n = \frac{2}{n} \sum\limits_{i=1}^n (8) + \frac{2}{n^2} \sum\limits_{i=1}^n(i)[/tex]
and
[tex]\sum\limits_{i=1}^n (i) = \frac{1}{2} n (n + 1)[/tex]
Therefore
[tex]K_n = \frac{72}{n} + \frac{2}{n^2} * \frac{1}{2} n (n + 1 )[/tex]
[tex]K_n = \frac{72}{n} + \frac{1}{n} (n + 1 )[/tex]
[tex]K_n = \frac{72}{n} + 1 + \frac{1}{n}[/tex]
[tex]K_n = \frac{72 + 1 + n }{n}[/tex]
[tex]K_n = \frac{n + 73 }{n}[/tex]
Now [tex]\lim_{n \to \infty} K_n = \lim_{n \to \infty} [\frac{n + 73 }{n} ][/tex]
=> [tex]\lim_{n \to \infty} [\frac{n + 73 }{n} ] = \lim_{n \to \infty} [\frac{n}{n} + \frac{73 }{n} ][/tex]
=> [tex]\lim_{n \to \infty} [\frac{n + 73 }{n} ] = \lim_{n \to \infty} [1 + \frac{73 }{n} ][/tex]
=> [tex]\lim_{n \to \infty} [\frac{n + 73 }{n} ] = \lim_{n \to \infty} [1 ] + \lim_{n \to \infty} [\frac{73 }{n} ][/tex]
=> [tex]\lim_{n \to \infty} [\frac{n + 73 }{n} ] = 1 + 0[/tex]
Therefore
[tex]\lim_{n \to \infty} K_n = 1[/tex]

In 2011, a U.S. Census report determined that 68% of college students are working students. A researcher thinks this percentage has changed and surveys 144 college students. The researcher reports that 93 of the 144 are working students. Is there evidence to support the researcher's claim at the 1% significance level
Answer:
We will fail to reject the null hypothesis and conclude that there is sufficient evidence not to support the researchers claim.
Step-by-step explanation:
We are given;
Population proportion; p = 68% = 0.68
Sample proportion; p^ = 93/144 = 0.6548
n = 144
The hypotheses are:
Null hypothesis;H0: p = 0.68
Alternative hypothesis;Ha: p ≠ 0.68
np = 144 × 0.6548 > 5 and nq = n(1 - p) = 144(1 - 0.68) > 5.
Since np and nq are more than 5, we can use the z-test .
z-formula in this case is;
z = (p^ - p)/√(p(1 - p))
Plugging in the relevant values, we have;
z = (0.6548 - 0.68)/√(0.68(1 - 0.6548))
z = -0.0252/0.4845
z = -0.052
From the z-table attached, we have a p-value of approximately 0.4801
P-value is higher than the significance level of 0.01.
Thus,we will fail to reject the null hypothesis and conclude that there is no sufficient evidence to support the researchers claim.

The question is not complete, so i have attached it.
Answer:
A) Option B: μ ≤ 19,000
B) Option C:
H0: μ ≤ 19,000
Ha: μ > 19,000
C) Option D: The null hypothesis H0: μ ≤ 19,000 is the claim
Step-by-step explanation:
A) From the question, we are told that an amusement park claims that the mean daily attendence at the park is at most 19,000 people.
Now, since it's at most 19000 people, it means that they are either 19000 or less. So the claim is;
μ ≤ 19,000 which is option B
B) Now, the claim is usually the null hypothesis. Thus, the null hypothesis is;
H0: μ ≤ 19,000
While the alternative hypothesis which states the opposite of the claim is;
Ha: μ > 19,000
So, option C is the correct answer
C) The claim is μ ≤ 19,000
Now, this also happens to be the null hypothesis.
Thus, the null hypothesis H0: μ ≤ 19,000 is the claim.
So option D is correct.
