1 answer:

7 0

<h2>Answer:</h2><h2>Roger's profit = %0.5 (I) - $7</h2><h2>The minimum number of cups of lemonade you have to sell in order to make a profit = 15</h2>

Step-by-step explanation:

Roger spends $7 to buy supplies for making lemonade.

Cost price = $7

He plans to sell each cup of lemonade for $0.50.

Selling price of one cup of lemonade = $ 0.5

Selling price of I cups = $0.5 (I)

(i) The equation that repesents profit earned by Roger is

Profit = Selling price - cost price

Profit = %0.5 (I) - $7

(ii) the minimum number of cups of lemonade you have to sell in order to make a profit is

By selling minimum 15 cups, the profit earned is

Profit = %0.5 (15) - $7

Profit = $0.5

Fiesta28 [93]

Answer:

Step-by-step explanation:

The first answer is correct because we have a decay factor.

The sample is losing mass, so the number that is being multiplied by a power of x must be less than 1.

If the second answer were used, then the sample would be gaining mass.

Answer:

0.15401

Step-by-step explanation:

Given that test statistic = 3.7408

From the question, we could deduce that, this is scenario could be analysed A ONE - WAY analysis of Variance method as it has one independent variable, Age subdivided into 3 levels

The test statistic value obtained is the Chisquare (χ²) value, which equals 3.7408

To Obtain the requested Pvalue, we need the degree of freedom, which is :

(Number of columns - 1) * (number of rows - 1)

Number of candidates = 2

Number of levels = 3

Hence,

Degree of freedom = (3 - 1) * (2 - 1) = 2 * 1 = 2

Using the Chisquare Pvalue calculator or distribution table :

χ²;3.7408, 2 = 0.154062

Pvalue = 0.1541

Question 8(Multiple Choice Worth 3 points)

Nastasia [14]

Answer: C) F(4) = 0

Detailed Explanation:

A zero/root of a polynomial is a value of the variable which makes the value of the polynomial to 0.

Therefore, when (x - 4) is a Factor :-
=> x - 4 = 0
=> x = 4

=> x = 4 is the Zero of the Polynomial.

If B is the midpoint of AC, AC=CD, AB=3x+4, AC=11x-17, and CE=49, find DE.

Luba_88 [7]

Answer:

Step-by-step explanation:

AB = 3x + 4 and AC which is twice of AB is equal to 11x - 17

2 (3x + 4) = 11x - 17

6x + 8 = 11x - 17

8 + 17 = 11x - 6x

25 = 5x

5 = x

AC = CD = 11x - 17 ➡ 11×5 - 17 = 38

CD = 38 and DE = 49 - 38 = 11
