A product-testing group compares two brands of trail mix to determine the number of raisins per ounce of mix. Two pounds of each brand's mix is separated into 32 one-ounce servings. The medians of the data distributions for Brand a and Brand B are -- Responses: A-equivalent to 12. B-greater than 12. C- less than 12. D- unable to be determined from the graph.
The data distribution for brand A is slightly skewed left while the data distribution for brand B is close to symmetric.
The medians of the data distributions for Brand A and Brand B are: greater than 12
How to identify the distribution pattern?Some of the terms in normal distribution spread are:
Right skewed: This is clearly where the mean is greater than the median. The mean overestimates the most common values in a positively skewed distribution.
Left skewed: This is clearly where the mean is less than the median.
Symmetric: In a symmetrical distribution, the mean, median, and mode are all equal.
1) Brand A distribution is left skewed because because there is a cluster of data on the right side
Brand B distribution is symmetric
2) The median of brand A will be the 16th and 17th dots which gives us:
(12 + 14)/2 = 13
Meanwhile, the median of brand B is:
(11 + 13)/2 = 12

The probability that the next Yankees game will be rained out is 2/5.
The probability that they will win their next game is 3/4.
What is he probability that it does not rain and the Yankees win?
(A) 11/20
(B) 5/9
(C) 9/20
(D) 1/4
Answer: C 9/20
Step-by-step explanation:
the odds the yankees don't get rain is 3/5. The odds they win are 3/4. 3/5x3/4=9/20
Answer:
(C), 9/20
Step-by-step explanation:
If the probability that the next Yankees game will be rained out is 2/5, this must mean than, theoretically, two times out of five, the game will be rained out.
This also means than three times out of five, it will not be rained out, so the probability that it will not be rained out is 3/5 (1-(2/5)=3/5)
We know that the probability that they will win their next game is 3/4.
We need to find the probability that it doesn't rain and the Yankees win. TO do this, we multiply both probabilities together. So, we have:
[tex]\frac{3}{5} *\frac{3}{4} =\\\\\frac{9}{20}[/tex]
So, the answer is (C), 9/20.

21.36/2 - 8.98/2 = 6.19
Answer:
$6.19
Step-by-step explanation:
You want the difference in price per pound between the cost of salmon at store B and the cost at store A.
Cost per poundThe cost per pound is found by dividing the cost by the corresponding number of pounds. The difference in cost will be the difference of those quotients.
cost at Store B - cost at Store A = ($21.36/(2 lb)) -($8.98/(2 lb))
= ($21.36 -8.98)/(2 lb) = $6.19/lb
It is $6.19 per pound more expensive to buy salmon at Store B than at Store A.

Which linear equation shows a proportional relationship?
y = 2x + 5
y equals one fifth times x minus 7
y equals negative one fifth times x
y = −5
Answer:
y = (-1/5)x
Step-by-step explanation:
The equation that represents a proportional relationship, or a line, is
y = k x , where is the constant of proportionality.
y = 2x + 5 (N0)
y equals one fifth times x minus 7 ------- y = (1/5)x -7 (No)
y equals negative one fifth times x ------y = (-1/5)x (Yes)
y = −5 (No)
Answer:D -> y equals one fifth times x minus 7
Step-by-step explanation: In a proportional relationship, when x is multiplied by a constant, then y will also be multiplied by the same constant. This means that the ratio between x and y remains constant throughout. In the given options, the equation "y equals one-fifth times x minus 7" follows the proportionality rule because when x is multiplied by 5, then y is also multiplied by 5, which means that the ratio between x and y remains constant throughout. Therefore, the correct option is "y equals one-fifth times x minus 7
Laila participated in a dance-a-thon charity event to raise money for the Animals are Loved Shelter. The graph shows the relationship between the number of hours Laila danced, x, and the money she raised, y.
Determine the slope and explain its meaning in terms of the real-world scenario.
The slope is 6, which means that the amount the student raised increases by $6 each hour.
The slope is one sixth, which means that the amount the student raised increases by $0.34 each hour.
The slope is 12, which means that the student will finish raising money after 12 hours.
The slope is 20, which means that the student started with $20.
Answer: The answer is A. The slope is 6, which means that the amount the student raised increases by $6 each hour.
Step-by-step explanation: I hope this help.
The correct interpretation is option (A) The slope is 6, which means that the amount the student raised increases by $6 each hour.
What is the Linear equation?A linear equation is an algebraic equation of the form y=mx+b, where m is the slope and b is the y-intercept, and only a constant and a first-order (linear) term are included. Sometimes, the aforementioned is referred to as a "linear equation of two variables," with y and x serving as the variables.
The slope is 6, which means that the amount of money Laila raised increases by $6 for every hour she danced. In other words, for each additional hour of dancing, Laila raised an additional $6 in donations.
This indicates a linear relationship between the number of hours Laila danced and the amount of money raised.
The y-intercept is 20, which means that when Laila did not dance at all, she still managed to raise $20 for the Animals are Loved Shelter.

Point A, located at (5, -4) is reflected in the y-axis, resulting in the location of point A'. Which of the following statements is true?
Point A' is located at (-5,-4)
Point A' is located at (-5,4)
Point A is located at (4,5)
Point A' is located at (-4,5)
The correct answer is Point A' is located at (-5, -4).
When a point is reflected in the y-axis, its x-coordinate is negated and its y-coordinate remains the same. Therefore, the x-coordinate of point A changes from +5 to -5, and the y-coordinate remains -4. Hence, the coordinates of A' are (-5, -4).

Which of the following sets of ordered pairs represents a function?
A: {(−4, −3), (−2, −1), (−2, 0), (0, −2), (0, 2)}
B: {(−5, −5), (−5, −4), (−5, −3), (−5, −2), (−3, 0)}
C: {(−4, −5), (−4, 0), (−3, −4), (0, −3), (3, −2)}
D: {(−6, −3), (−4, −3), (−3, −3), (−2, −3), (0, 0)}
Answer:
A set of ordered pairs represents a function if each input (first coordinate) corresponds to one and only one output (second coordinate). In other words, there can't be two different second coordinates for the same first coordinate.
Using this definition, we can determine which of the sets of ordered pairs represents a function:
A: {(-4, -3), (-2, -1), (-2, 0), (0, -2), (0, 2)}
The input -2 has two different outputs (-1 and 0), and the input 0 also has two different outputs (-2 and 2). Therefore, this set does not represent a function.
B: {(-5, -5), (-5, -4), (-5, -3), (-5, -2), (-3, 0)}
The input -5 has four different outputs (-5, -4, -3, and -2), but each of the other inputs has only one output. Therefore, this set does not represent a function.
C: {(-4, -5), (-4, 0), (-3, -4), (0, -3), (3, -2)}
The input -4 has two different outputs (-5 and 0), but each of the other inputs has only one output. Therefore, this set does not represent a function.
D: {(-6, -3), (-4, -3), (-3, -3), (-2, -3), (0, 0)}
Each input has only one output, so this set represents a function.
Therefore, the set of ordered pairs that represent a function is D: {(-6, -3), (-4, -3), (-3, -3), (-2, -3), (0, 0)}.

Anthony measures the height of a plant at the beginning and the end of summer. Beginning of summer in June the pant was 12 3/8 inches but at the end of summer in September the plant was 14 inches.
PT1.A. How many inches did the plant grow?
PT2.B. Anothony planted the seed in March. How much did the plant grow per month prior to him measuring in June?
ANSWER BOTH QUESTIONS A AND B
PT1.A — 1 5/8 (1.625) inches
PT2.B — 2 7/16 (2.4375) inches
Step-by-step explanation (PT1.A):Height of the plant in the Beginning of summer = 12 3/8 inches
Height of the plant at the End of summer = 14 inches
Growth of the plant = Height of the plant in the Beginning of summer - Height of the plant at the End of summer.
Growth of the plant = 14 - 12 3/8
= 14 - 99/8
= 112/8 - 99/8
= 13/8
= 1 5/8 inches
= 1 + 0.625 (Decimal)
= 1.625 inches (Decimal)
You can write the answer as 1 5/8 inches or 1.625 inches. I just converted the fraction into a decimal.
As we can observe from the previous question, Anothony planted the seed in June and it grown 1 5/8 (1.625) inches by September.
Height of plant grown = 1 5/8 (1.625) inches
Number of months from June to September = 2 months
Height of plant grown per month = Height of plant grown / Number of months from June to September
Height of plant grown per month = 1 5/8 (1.625) / 2
= 13/8 (1.625) / 2
= 13/16 (0.8125) inches
So, the plant grows 13/16 (0.6125) inches per month.
Number of months from March to June = 3 months
Height of plant grown per month = 13/16 (0.8125) inches
Growth of plant grown from March to June = Number of months from March to June * Height of plant grown per month
Growth of plant grown from March to June = 3 * 13/16 (0.8125)
= 39/16 (2.4375)
= 2 7/16 (2.4375) inches

The following scatter plot represents the scores of thirteen students on a geography test compared to the number of hours that each student studied for the test. Use the line of best fit to predict the score of a student who studied three hours for the test.
Answer:
95
Step-by-step explanation:
Looking at the graph, we can find the red line. The red line passes through the following coordinates (x,y): (0,65), (1, 75), (2, 85) and (3,95).
We know that x is the number of hours studied, and y is the score. If x=3, and y=95, then a student that studied three hours for the test will most likely score 95%.
