The graph shows the data points in the table and the exponential regression model associated with the data. A 2-column table with 5 rows. The first column is labeled days after treatment with entries 2, 4, 6, 8, 10. The second column is labeled number of weeds with entries 100, 26, 6, 2, 1. A graph shows days after treatment labeled 1 to 11 on the horizontal axis and number of weeds on the vertical axis. A line shows a downward trend. Based on the graph of the regression model, which is true? The number of weeds is decreasing by a multiplicative rate. The number of weeds is increasing by a multiplicative rate. The number of weeds is decreasing by an additive rate. The number of weeds is increasing by an additive rate.

Thompson's market sells a 25 pound bag of happy chow dog food for $15.49 and a 30 pound bag of super chow dog food for $17.39 which brand is the better buy?Explain

Answers

Answer:

The better buy would be super chow since the price per pound($0.58) is cheaper than Happy chow's $0.62 so a buyer gets the same quantity but at a cheaper price

Step-by-step explanation:

Happy chow is $15.49 for 25 pounds

The price per pound Happy chow=15.49/25 =$0.62

Super chow is $17.39 for 30 pounds

The price per pound of Super chow=17.39/30=$0.58

Happy chows($0.62)>Super chow ($0.58)

The better buy would be Super chow since the price per pound($0.58) is cheaper than Happy chow's $0.62 so a buyer gets the same quantity but at a cheaper price

A coin is tossed ten times. The probability of heads on each toss is 0.5. Evaluate the probability of getting exactly 6 heads.

Answers

The probability of getting exactly 6 heads is: 10!/6!(10-6)! * (1/2)^6 (1 - 1/2)^4 = 0.205 or 20.6 %

Line KL has an equation of a line y = 4x + 5. Which of the following could be an equation for a line that is perpendicular to line AB? (6 points)y = 4x − 8

y = 1 over 4x − 8

y = −4x − 8

y = −1 over 4x − 8

Answers

To find a perpendicular slope (or line), the slope (in this case 4x) must be the opposite sign and its reciprocal, which is basically the fraction flipped upside down. Since 4 is technically 4/1, that fraction flipped is 1/4. And since you need to flip the sign too, instead of it being a positive number, it's negative. Your answer is -1/4x-8

y = -1 over 4x - 8 is the answer I think

Please choose the answer that describes the scientific notation for 5,098,000.a. 5.098 108
b. 5.098 75777
c. 5.098 106
d. 5.098 107

Answers

Scientific notation is the representation of a number in a power of ten, with a sequence of digits placing the comma after the first digit, and the power or then that is mathematically consistent with the number. For example 400 is 4.00 * 10^2; 3100 is 3.100 * 10^4; 13421 = 1.3421 * 10 ^4. It is important that you have only one digit before the comma. So, 5,098,00 is 5.098 * 1,000,00 = 5.098 * 10^6. The answer is the option c. 5.098 * 10^6.
