A real-life situation for this inequality could be "Tom runs a lemonade stand. His profit is x. If Tom knows that his profit is less than 2 dollars, what inequality represents this situation?"
I am pretty sure the value of ‘n’ is 2.5!
Answer:
The amount of money separating the lowest 80% of the amount invested from the highest 20% in a sampling distribution of 10 of the family's real estate holdings is $238,281.57.
Step-by-step explanation:
Let the random variable <em>X</em> represent the amount of money that the family has invested in different real estate properties.
The random variable <em>X</em> follows a Normal distribution with parameters <em>μ</em> = $225,000 and <em>σ</em> = $50,000.
It is provided that the family has invested in <em>n</em> = 10 different real estate properties.
Then the mean and standard deviation of amount of money that the family has invested in these 10 different real estate properties is:
Now the lowest 80% of the amount invested can be represented as follows:
The value of <em>z</em> is 0.84.
*Use a <em>z</em>-table.
Compute the value of the mean amount invested as follows:
Thus, the amount of money separating the lowest 80% of the amount invested from the highest 20% in a sampling distribution of 10 of the family's real estate holdings is $238,281.57.
<span>We have to find the value of x if the measures of the angles of a triangle are: 2 x, 3 x and 4 x. We know that the sum of the measures of the angles of a triangle is 180 degrees. A + B + C = 180. Here we have: A = 2 x, B = 3 x and C = 4 x; 2 x + 3 x + 4 x = 180; 9 x = 180; x = 180 : 9. Answer: x = 20 degrees.</span>
Answer:
a) 7t - 560 ≤ 140 is the required inequality to represent the situation.
Step-by-step explanation:
Let t represent the number of tickets sold.
The amount allocated by school council for all supplies = $560
The selling price of each ticket = $7
The aim to earn profit = more than $140
Goal reached if Number of tickets sold = 100
Now, SP of each ticket is $7
⇒Selling price of t tickets = t x ($7) = 7t
PROFIT = TOTAL SELLING Price - TOTAL COST
or, $140 = 7t - $560
According to the question:
7t - 560 ≤ 140
if t = 100, then the profit earned = 7(100) - 560 = 140
Hence, t = 100 is the possible solution of the given expression.
