Tennis balls: Must rebound approximately 111 cm when dropped from 200 cm. Soccer balls: Must rebound approximately 120 cm when dropped from 200 cm onto a steel plate. Basketballs: Must rebound approximately 53 .5 inches when dropped from 72 inches onto a wooden floor. Squash balls: Must rebound approximately 29 .5 inches when dropped from 100 inches onto a steel plate at 70∘ Which ball listed above is the bounciest
Answers
Answer:
There is no basis for comparison because the effect of the other variables that are not being studied are not minimized
Step-by-step explanation:
The rate at which each type of ball bounce are;
Tennis balls;
The height to which the ball is must rebounds ≈ 111 cm
The height from which the ball is dropped = 200 cm
Surface = Steel plate
Basketballs;
The height to which the ball must rebounds ≈ 5.35 inches
The height from which the ball is dropped = 72 inches
Surface = Wooden floor
Squash balls
The height to which the ball must rebounds ≈ 29.5 inches
The height from which the ball is dropped = 100 inches
Steel plate at 70°
Therefore, given that the experimental are performed with different variables of height from which each type of ball is dropped, the surface to which the ball is dropped, the angle of the surface to which the ball is dropped, there is no controlled variable to provide a basis for comparison
the data listed here are the weights (in pounds) of 29 packages of beef in a supermarket meat display
Answers
The difference between the mean and the median in this case may indicate that the distribution of weights is skewed, particularly due to the presence of outliers.
The given data represents the weights of 29 packages of beef in a supermarket meat display. To analyze the distribution, we can construct a histogram. Upon analyzing the data, it appears that there are some outliers (-75 and -89), which may need to be investigated further. However, without specific class boundaries provided, we can observe the general shape of the distribution.
The mean and median are two measures of center in a distribution. The mean is calculated by summing all the values and dividing by the number of observations, while the median represents the middle value when the data is arranged in ascending or descending order. The mean gives us an idea about the average weight of the packages, while the median represents the middle value of the distribution.
In terms of the symmetry or skewness of the distribution, the mean is influenced by extreme values or outliers, as it takes into account the magnitude of each value. On the other hand, the median is less affected by outliers and provides a better representation of the central tendency of the distribution. If the distribution is skewed or contains outliers, the mean may deviate from the median, reflecting the asymmetry in the data.
Therefore, the difference between the mean and the median in this case may indicate that the distribution of weights is skewed, particularly due to the presence of outliers.

aldo has scored 77, 88, 77, 87, and 63 on his previous five tests. what score does he need on his next test so that his average (mean) is 79?
Answers
To maintain an average of 79, Aldo must obtain a score of 82 in his upcoming exam.
To get the solution, let's calculate the total of the first five scores.
Total of the first five scores = 77 + 88 + 77 + 87 + 63 = 392
Now we know that there are a total of six scores, so to get the mean, we will divide the total by six.
Mean = Total/Number of ScoresTherefore, 79 = 392 + x/6
We need to find the value of x that will satisfy the above equation.
Now we will solve for x.79 = 392 + x/6
(Multiply both sides by 6) 6 * 79 = 6 * 392 + x6 * 79 = 2352 + xx = 6 * 79 - 392x = 474 - 392x = 82
Therefore, Aldo needs to score 82 on his next test to achieve an average of 79.

Current standards suggest that a single subject research design can demonstrate a functional relation between the independent and dependent variables with a minimum of __________ effects.
Answers
Current standards indicate that a single subject research design should demonstrate a functional relation between independent and dependent variables with a minimum of three effects.
Single subject research designs, also known as single case experimental designs, are experimental designs commonly used in behavioral sciences to study the effects of interventions or treatments on individuals. These designs involve repeated measurement of the dependent variable under different conditions or phases.
To establish a functional relation between the independent and dependent variables, current standards suggest that a minimum of three effects should be demonstrated. These effects typically consist of a baseline phase, an intervention phase, and a return-to-baseline phase. The baseline phase serves as a control condition where the independent variable is absent or has no effect on the dependent variable. The intervention phase introduces the independent variable, and its effects on the dependent variable are observed.

A home has a rectangular kitchen. if listed as ordered pairs, the corners of the kitchen are (8, 4), (−3, 4), (8, −8), and (−3, −8). what is the area of the kitchen in square feet? 20 ft2 46 ft2 132 ft2 144 ft2
Answers
The area of the kitchen in square feet is 132\(ft^{2}\)
To find the area of the rectangular kitchen, we need to multiply the length by the width.
The length of the kitchen can be found by subtracting the x-coordinates of the two points on the same vertical side. So, the length is 8 - (-3) = 11 feet.
The width of the kitchen can be found by subtracting the y-coordinates of the two points on the same horizontal side. So, the width is 4 - (-8) = 12 feet.
Therefore, the area of the kitchen is:
Area = Length x Width = 11 ft x 12 ft = 132 square feet

Find the equation of a line parallel to y + 9 = -3/2x that passes through the point (-8,9)
Answers
slope intercept form:
y = mx + b (where m = slope
and b = y-intercept)
simply subtract 9 from both sides of the given equation to get slope intercept form of the first line:
y + 9 = -3/2x
y + 9 - 9 = -3/2x - 9
y = -3/2x - 9
so the slope (m) = -3/2
the problem tells us a point on the second line (x,y) or (-8,9)
and we now know slope is -3/2
so let’s plug those in and solve for the y-intercept (b) of the second line.
y = mx + b
9 = -3/2(-8) + b
9 = 12 + b
9 - 12 = 12 - 12 + b
-3 = b
so now we know the slope (m) of both lines is -3/2 and the y-intercept (b) of the second line is -3
all we have to do is use the information to establish slope intercept form of the equation of the second line:
y = mx + b
y = -3/2x - 3
The answer is: y = -3/2x - 3
check your answer by plugging the point (-8,9) back in to your equation
9 = -3/2(-8) - 3
9 = 12 - 3
9 = 9 [TRUE]

Answers
Answer:
$14,850
Step-by-step explanation:
If the factory can sell 225 bottles each hour, then for a 12 hour shift, 225 * 12 = 2,700 bottles sold. 5.50 * 2,700 = 14,850, so the factory makes $14,850.
find an equation of the tangent line to the given curve at the specified point. y = x 2 − 1 x 2 x 1 , ( 1 , 0 )
Answers
The equation of the tangent line to the curve \(y = \frac {(x^2 - 1)}{ (x^2 + x + 1)}\) at the point (1, 0) is y = (2/3)x - 2/3.
To find the equation of the tangent line to the curve at the point (1, 0), we need to find the slope of the tangent line and then use the point-slope form of a linear equation.
Let's differentiate \(y = \frac {(x^2 - 1)}{ (x^2 + x + 1)}\) using the quotient rule:
\(y' = [(2x)(x^2 + x + 1) - (x^2 - 1)(2x + 1)] / (x^2 + x + 1)^2\)
Substituting x = 1 into the derivative expression:
\(y'(1) = [(2(1))(1^2 + 1 + 1) - (1^2 - 1)(2(1) + 1)] / (1^2 + 1 + 1)^2\)
\(= [2(3) - (0)(3)] / (3)^2\)
= 6/9
= 2/3
Using the point-slope form y - y₁ = m(x - x₁), where (x₁, y₁) = (1, 0) and m = 2/3 we get,
y - 0 = (2/3)(x - 1)
y = (2/3)x - 2/3
The point-slope form of a linear equation is given by y - y₁ = m(x - x₁) where (x₁, y₁) is a point on the line, and m is the slope of the line.
Therefore, the equation of the tangent line to the curve y = (x^2 - 1) / (x^2 + x + 1) at the point (1, 0) is y = (2/3)x - 2/3.

Answers
The closest answer is 80 cupcakes per minute, so the correct option is .8. The closest answer is 165 minutes, so the correct option is 165.
The throughput capacity of the icing stage can be calculated by dividing the number of cupcakes in a batch (100) by the time required to process each cupcake (1.25 minutes).
Throughput capacity = Number of cupcakes in a batch / Time to process each cupcake
Throughput capacity = 100 cupcakes / 1.25 minutes
Throughput capacity = 80 cupcakes per minute
The closest answer is 80 cupcakes per minute, so the correct option is .8.
The throughput time for a batch of cupcakes is the time required to process the entire batch, including the setup time.
Throughput time = Time for setup + (Number of cupcakes in a batch * Time to process each cupcake)
Throughput time = 40 minutes + (100 cupcakes * 1.25 minutes per cupcake)
Throughput time = 40 minutes + 125 minutes
Throughput time = 165 minutes
The closest answer is 165 minutes, so the correct option is 165.

A diver is 50 ft below sea level. Which integer correctly represents the situation?
Answers
Answer:
50 feet below sea level. First, look for keywords. The word “below” means you will need to use a negative integer. The answer is -50.
Step-by-step explanation:
hope this helps...
(─‿─)
Negative integers are used to represent values below zero, and in this context, "-50" represents a depth of 50 feet below the sea level.
In the context of sea level and vertical position, we often use positive and negative numbers to represent positions above or below a reference point, which is usually considered to be sea level.
When we say the diver is 50 feet below sea level, it means the diver is at a depth of 50 feet under the surface of the sea. In this case, we use negative numbers to represent positions below sea level.
So, if we consider sea level as the reference point (zero level), the number line extends in both positive and negative directions. Positive numbers represent positions above sea level, and negative numbers represent positions below sea level.
Since the diver is 50 feet below sea level, we represent this as -50. The negative sign indicates that the diver is below the reference point (sea level), and the absolute value of 50 represents the depth of 50 feet.
Therefore, the integer -50 correctly represents the situation of a diver being 50 feet below sea level.
