Nina bought 1.725 pounds of pecans and 1.83
pounds of almonds. She also bought twice as many
pounds of walnuts as pecans. How many more
pounds of walnuts did she buy than almonds?
Nina bought 3.45 pounds of walnut.
Nina bought 1.62 pounds more walnut than almonds
Quantity of pecan bought by Nina = 1.725 pounds
Quantity of almonds bought by Nina = 1.83 pounds
The process of comparison of numbers establishes the similarities between two numbers and determines which number is greater, smaller, or equal to another number.
Quantity of walnuts = 2*Quanitity of pecans
= 2*1.725
= 3.45 pounds
So, she bought 3.45 pounds of walnut
Pounds of walnuts bought more than the almonds = Quantity of walnuts bought by Nina - Quantity of almonds bought by Nina
= 3.45 - 1.83
= 1.62 pounds
So, she bought 1.62 pounds more walnuts than almonds

The probability that the student is a sixth-grader or rated good grades as most important is (168 / 335) + (135 / 335) = 0.904
What is the probability?Probability is used to determine the odds that a random event would happen. The odds that the event would happen lies between 0 and 1.
The probability that the student is a sixth-grader or rated good grades as most important = (number of sixth-graders / total number of students) + (students who rates good grades as most important / total number of students)
(168 / 335) + (135 / 335) = 303 / 335 = 0.904

The cost of each bottle of juice is $0.51.
What is a tape diagram?The tape diagram can be used to illustrate the relationship between the numbers that are given.
Let the cost of each bottle of juice be x.
In this case, she bought a bag of oranges for $2.19 and a 12-pack of juice bottles and the total cost before tax was $8.31.
This will be:.
2.19 + 12x = 8.31

you have a sample of contaminated benzoic acid that weighs 2.014 g. after performing a proper recrystallization with proper drying, the mass of your purified benzoic acid is 1.611 g. what is your percent recovery rounded to the nearest tenths? do not include the percent symbol in your answer (e.g., if your answer is 10.5%, submit your answer as 10.5).
The percent recovery of benzoic acid is equal to 80.0 if the mass of purified benzoic acid after recrystallization is 1.611 g.
The percent recovery can be described as the amount of a product available after its production and purification.
The percent recovery of benzoic acid can be calculated by using the following formula:
percent recovery of sample = (Mass of purified sample ÷ Mass of contaminated sample) × 100
Substituting the given values of contaminated and purified benzoic acid in this equation;
percent recovery = (1.611 ÷ 2.014) × 100
percent recovery = 0.7999 × 100
percent recovery = 79.99
Rounding it to the nearest tenth;
percent recovery = 80.0
Hence the percent recovery of benzoic acid is calculated to be 80.0

The daytime temperature in Montana yesterday was -4.5 degrees, and it was expected to drop 6.5 more degrees today. What is today’s expected daytime temperature?
-11 degrees is the expected daytime temperature for today
The daytime temperature yesterday in Montana = -4.5 degrees
Expected temperature drop today = 6.5 degrees
The term "temperature" describes how hot or cold the atmosphere is and is measured with a thermometer. Temperature is reported by meteorologists in both Celsius (C) and Fahrenheit (F).
Today's expected daytime temperature:
The daytime temperature yesterday in Montana + Expected temperature drop today
But since the temperature of yesterday is negative we will use a negative sign to add the expected temperature of today. A drop in temperature will lead to a more cold temperature
= -4.5 + (-6.5)

choose if the following statement is true or false: correlation is sensitive to the scale of the data; however, covariance is not sensitive to the scale of the data
Correlation is not sensitive to the scale of the data; however, covariance is sensitive to the scale of the data, so the statement is false.
Covariance is a term used in statistic and regression analysis. Covariance shows how two variables differ.
Covariance is affected by the change in scale, for example if all the value of one variable is multiplied by a constant and all the value of another variable are multiplied, by the same or another constant all together, then the covariance is automatically changed.
Correlation is also a term used in regression analysis and statistics. Correlation shows how two variables are related and therefore not influenced by the change in scale.

A model rocket reaches a maximum height of 2000 feet above ground and begins to
descend at a rate of 75 feet per second. Which equation models the height above
ground, y, of the model rocket, x seconds after it reaches its maximum height?
The equation which is best representing the height above ground, y, of the model rocket and x seconds after it reaches the maximum height is 75x + y = 2000.
The height above ground, y, of the model rocket, x seconds after it reaches its maximum height can be represent by a linear equation,
The maximum height is 2000 feet, after this the rocket starts to descend with a rate of 75 feet per second.
Let us say that when the rocket starts descending, our time is started from zero,
So, on plotting these points of graph, we can one point, (0,2000).
The rate of descend is the slope m of the graph,
m = -75 ft/s
We are taking it negative because height is decreasing with time,
We can use the point slope form of equation of line,
It says, if a line passes through (a,b) and has slope m. Then the equation of line is,
(y-b) = m(x-a)
So, our line is passing through (0,2000) and has slope -75 ft/s.
So, equation of the line is,
(y-2000) = -75(x-0)
75x + y = 2000.
This above equation of line is representing the relation between the height above ground and time of the model rocket.
