Question 60:
The answer is B. 25.57.
Mean is calculated by adding up all the values of a data set, and then dividing that sum by the amount of values.
25, 32, 16, 21, 30, 18, 37=179
179÷7=25.57
Question 61:
The answer is A. 102.
Mode is the number in a data set that appears most often. 102 shows up twice, while the other values only appear once. So 102 is the mode.
The correct representation of the scale is 1 inch:2 feet
<h3>What are scale ratios?</h3>
Scale ratios are used to show the relationship between quantities of different measurements
The scale is given as:
1 inch = 2 feet
Represent the above scale, as ratio
Hence, the correct representation of the scale is 1 inch:2 feet

Answer:
20
Step-by-step explanation:
4 * 1 = 4 5 * 1 = 5
4 * 2 = 8 5 * 2 = 10
4* 3 = 12 5 * 3 = 15
4 * 4 = 16 5 * 4 = 20
4 * 5 = 20
they both go into 20 equally. there is no number lower than 20 that they both go into
Answer:
The z-score for the 34-week gestation period baby is 0.61
Step-by-step explanation:
The formula for calculating a z-score is is z = (x-μ)/σ,
where x is the raw score,
μ is the population mean
σ is the population standard deviation.
We are told in the question that:
Babies born after a gestation period of 32-35 weeks have a mean weight of 2600 grams and a standard deviation of 660 grams. Also, we are supposing a 34-week gestation period baby weighs 3000grams
The z-score for the 34-week gestation period baby is calculated as:
z = (x-μ)/σ
x = 3000, μ = 2600 σ = 660
z = 3000 - 2600/660
= 400/660
=0.6060606061
Approximately, ≈ 0.61
The domain of the third piece of the graph is contained in interval <u>B. (12, 20)</u>.
<h3>What is the domain of a graph?</h3>
The domain of a graph consists of all the input values shown on the x-axis.
The input values (domain) are shown on the x-axis, unlike the range, whose output values are shown on the y-axis.
Therefore, the domain comprises the independent variables or values, which can be determined using the function, y = f(x).
Thus, the domain of the third piece of the graph can be determined in interval <u>B. (12, 20)</u>.
