Out of a total of 500 people [both male and female], we need to find female Walmart shoppers.
If you down Walmart column and intersect with Women row, we see that Female Walmart Shoppers = 73
Hence,
Probability(women, Walmart) = 73/500 = 0.146
In percentage:
0.146 * 100 = 14.60%
The answer in percentage, rounded to nearest hundredth, is

1/3 + 3/5 + 7/9 + 13/15
Answer:
116 / 45
Step-by-step explanation:
To add fractions with unlike denominators, we need to find their common denominator.
One way to do this is by finding the least common multiple (LCM) of the denominators.
The LCM of 3, 5, 9 and 15 is 45.
We then convert each fraction so that its denominator is 45:
1/3 = 15/45
3/5 = 27/45
7/9 = 35/45
13/15 = 39/45
Now we can add the fractions:
15/45 + 27/45 + 35/45 + 39/45
To simplify, we can add the numerators and keep the common denominator:
(15 + 27 + 35 + 39) / 45
Which gives us:
116 / 45
Therefore, the sum of the fractions 1/3 + 3/5 + 7/9 + 13/15 is, 116 / 45.

Suppose a consumer group suspects that the proportion of households that have three cell phones NOT known to be 30%. A cell phone company has reason to believe that the proportion is 30%. Before they start a big advertising campaign, they conduct a 99% CL hypothesis test. Their marketing people survey 150 households with the result that 43 of the households have three cell phones.
Required:
a. Is the actual percentage of households different from 30%?
b. Set up the hypothesis test.
c. What is the success for this problem?
d. Calculate the p-value.
e. Draw conclusion.
Answer:
We conclude that the actual percentage of households is equal to 30%.
Step-by-step explanation:
We are given that a consumer group suspects that the proportion of households that have three cell phones NOT known to be 30%.
Their marketing people survey 150 households with the result that 43 of the households have three cell phones.
Let p = proportion of households that have three cell phones NOT known.
So, Null Hypothesis, \(H_0\) : p = 30% {means that the actual percentage of households is equal to 30%}
Alternate Hypothesis, \(H_A\) : p \(\neq\) 30% {means that the actual percentage of households different from 30%}
The test statistics that would be used here One-sample z-test for proportions;
T.S. = \(\frac{\hat p-p}{\sqrt{\frac{p(1-p)}{n} } }\) ~ N(0,1)
where, \(\hat p\) = sample proportion of households having three cell phones = \(\frac{43}{150}\) = 0.29
n = sample of households = 150
So, the test statistics = \(\frac{0.29-0.30}{\sqrt{\frac{0.30(1-0.30)}{150} } }\)
= -0.27
The value of z test statistic is -0.27.
Also, P-value of the test statistics is given by;
P-value = P(Z < -0.27) = 1 - P(Z \(\leq\) 0.27)
= 1 - 0.6064 = 0.3936
Now, at 1% significance level the z table gives critical value of -2.58 and 2.58 for two-tailed test.
Since our test statistic lies within the range of critical values of z, so we have insufficient evidence to reject our null hypothesis as it will not fall in the rejection region due to which we fail to reject our null hypothesis.
Therefore, we conclude that the actual percentage of households is equal to 30%.

Consider the following example, Country A can use its resources to make him 200 pounds of coffee or he can make 70 pounds of tea (but not both). With the same resources, country B can make 180 pounds of coffee for her or 50 pounds of tea for him. Country A has an absolute advantage over both products. Company A should produce 3x or 6y per unit operation and Company B should produce 3x or 3y per unit operation. So, company A has absolute advantage.

Allen Siegell has a personal injury protection policy that covers each person in, on, around, or under his car for medical expenses up to $50,000. He is involved in an accident and five people in his car are hurt. One person has $3,000 or medical expenses, three people each have $500 worth of medical expenses, and Allen himself has medical expenses totaling $62,000. How much money must the insurance company pay out for these five people?
The total medical expenses for the five people in the car are $3,000 + $3*$500 + $62,000 = $3,000 + $1,500 + $62,000 = $66,500

1.7 Basil Yamey is setting up a new business. Before selling anything, he bought a van for £9,000; a
transportable market stall for £1,800; a computer for £280; and an inventory of goods for £11,200. Fie
did not pay in full for his inventory of goods and still owes £5,000 for them. Fie borrowed £8,000 from
Luca Pacioli. After the eventsjust described, and before trading starts, he has £900 cash in hand and
£6,300 in the bank. Calculate the amount of his capital.
Answer:
the amount of Basil Yamey's capital is £16,480.
Step-by-step explanation:
To calculate Basil Yamey's capital, we need to add up the value of his assets and subtract his liabilities.
The value of his assets is:
Van: £9,000
Market stall: £1,800
Computer: £280
Inventory of goods: £11,200
Cash in hand: £900
Money in the bank: £6,300
Total value of assets = £9,000 + £1,800 + £280 + £11,200 + £900 + £6,300 = £29,480
His liabilities are:
Amount still owed for inventory of goods: £5,000
Amount borrowed from Luca Pacioli: £8,000
Total liabilities = £5,000 + £8,000 = £13,000
Therefore, Basil Yamey's capital is:
Capital = Total value of assets - Total liabilities
Capital = £29,480 - £13,000 = £16,480
So the amount of Basil Yamey's capital is £16,480.
Answer:
Basil Yamey's capital is the total amount of money that he has invested in his business. This can be calculated as the sum of the cost of the assets that he has purchased, minus any outstanding debts, plus any cash or cash equivalents he has on hand.
The cost of the assets that Basil has purchased is:
£9,000 (van) + £1,800 (market stall) + £280 (computer) + £11,200 (inventory) = £21,280
He still owes £5,000 for the inventory, so the total cost of the assets minus the outstanding debt is:
£21,280 - £5,000 = £16,280
He borrowed £8,000, so the total amount of his capital is:
£16,280 + £8,000 = £24,280
He also has cash on hand and in the bank:
£900 (cash) + £6,300 (bank balance) = £7,200
So, Basil Yamey's total capital is £24,280 + £7,200 = £31,480.

Write an equation of the line passing through point P(-6, 4) that is perpendicular to y + 8 = 2(x - 14). Graph the equations to check that the lines are perpendicular.
Answer: An equation of the line passing through point P(-6, 4) that is perpendicular to y + 8 = 2(x - 14) is:
y = -4x + 20
Step-by-step explanation:
The given equation is in slope-intercept form y = mx + b, where m is the slope of the line and b is the y-intercept. The slope of the line is 2, which means the line has a slope of 2 and is inclined at an angle of tan^-1(2).
To find an equation of a line that is perpendicular to this line, we need to find the negative reciprocal of the slope, which is -1/2. This means the slope of the line passing through point P(-6, 4) that is perpendicular to y + 8 = 2(x - 14) is -1/2.
Now we can use the point-slope form of a linear equation to find the equation of the line passing through point P(-6, 4) and having a slope of -1/2. The point-slope form of a linear equation is:
y - y1 = m(x - x1)
Where (x1, y1) is the given point, and m is the slope of the line. So by substituting the values we get:
y - 4 = -1/2(x + 6)
Which can be written as:
y = -1/2x + 4
So the equation of the line passing through point P(-6, 4) that is perpendicular to y + 8 = 2(x - 14) is:
y = -1/2x + 4
Graphing the equations can confirm that the lines are perpendicular as the slope of the first line is 2 and the slope of the second line is -1/2, the product of these slopes is -1 which means they are perpendicular to each other.
use the definition of countinuity to find the value of k so that the function is continuous for all real numbers
First of all, recall the definition of absolute value:
\(|x| = \begin{cases}x&\text{if }x\ge0\\-x&\text{if }x<0\end{cases}\)
So if x < 4, then x - 4 < 0, so |x - 4| = -(x - 4), and the first case in h(x) reduces to
\(\dfrac{|x-4|}{x-4}=\dfrac{-(x-4)}{x-4} = -1\)
Next, in order for h(x) to be continuous at x = 4, the limits from either side of x = 4 must be equal and have the same value as h(x) at x = 4. From the given definition of h(x), we have
\(h(4) = 5k-4\cdot4 = 5k-16\)
Compute the one-sided limits:
• From the left:
\(\displaystyle \lim_{x\to4^-}h(x) = \lim_{x\to4}\frac{|x-4|}{x-4} = \lim_{x\to4}(-1) = -1\)
• From the right:
\(\displaystyle \lim_{x\to4^+}h(x) = \lim_{x\to4}(5k-4x) = 5k-16\)
If the limits are to be equal, then
-1 = 5k - 16
Solve for k :
-1 = 5k - 16
15 = 5k
k = 3
