Answer:
<h2>
min: 52</h2><h2>
max: 78</h2><h2>
median: 63</h2><h2>
lower quartile median: 54</h2><h2>
upper quartile median: 73</h2><h2>
interquartile range: 19</h2>
Step-by-step explanation:
the temperatures ordered from least to greatest
52, 53, 54, 54, 57, 62, 64, 69, 73, 73, 77, 78
the min is 52
the max is 78
median:
52, 53, 54, 54, 57, 62, 64, 69, 73, 73, 77, 78
(62+64)/2=126/2=63
thus the median is 63
now we don't include the median in finding the upper and lower quartile medians:
lower quartile median:
52, 53, 54, 54, 57, 62
54 (same #s no need to add up and divide by 2)
upper quartile median:
64, 69, 73, 73, 77, 78
73 (same #s no need to add up and divide by 2)
interquartile range is:
upper quartile median-lower quartile median:
73-54
19
Answer:
Continuous.
Step-by-step explanation:
In Mathematics, a random variable can be defined as any variable whose values are determined by the outcome of a random experiment.
Basically, random variables are classified into two (2) main categories and these are;
1. Discrete random variable: a discrete random variable is a data set in which the number of possible values are either finite or countable. For instance, the value of a fair die, number of sweets in a jar, number of eggs in a crate etc.
2. Continuous random variable: a continuous random variable is a data set having infinitely many possible values and those values cannot be counted, meaning they are uncountable. Any quantity such as height, volume, weight, density, length, pressure, temperature, speed, distance, time are generally a continuous random variable.
Hence, the weight of a rock is continuous random variable because it has an infinite number of possible values such as 1kg, 20kg, 10kg, 50kg etc.
We have
(1) two rectangles 3' × 5'
(2) two rectangles 3' × 6'
(3) two rectangle 5' × 6'
The formula of an area of a rectangle: A = lw
l - length
w - width
A(1) = 3 · 5 = 15 in²
A(2) = 3 · 6 = 18 in²
A(3) = 5 · 6 = 30 in²
The Total Area:
<h3>T.A. = 15 + 18 + 30 = 63 in²</h3>
Answer:
Q is P reflected across the y-axis; only the signs of the y-coordinates of P and Q are different.
