I believe the correct response would be B. Real numbers and natural numbers.
First thing to note, QR + RS = QS
#1, RS = 44.6 and SQ = 68.4
Plug in to the equation I wrote above
QR + 44.6 = 68.4
QR = 23.8
#2, RS = 33.5 and RQ = 80
QR + 33.5 = 80
QR = 46.5
Answer:
12083.929
Step-by-step explanation:
First step: find the mean of the data.
mean = <u>3</u><u>+</u><u>3</u><u>3</u><u>+</u><u>3</u><u>0</u><u>3</u><u>+</u><u>2</u><u>3</u><u>3</u><u>+</u><u>3</u><u>+</u><u>7</u><u>3</u><u>+</u><u>8</u><u>3</u><u>+</u><u>6</u><u>3</u>
8
= <u>7</u><u>9</u><u>4</u>
8
= 99.25
Second step: Now we calculate each dog's difference from the Mean.
Example : 3–99.25=96.25
Answer: (-96.25)+(-66.25)+203.75+133.75+(-96.25)+(-26.25)+(-16.25)+(36.25)
Third step: To calculate the Variance, take each difference, square it, and then average the result.
s² = <u>(-96.25)</u><u>²</u><u>+(-66.25)</u><u>²</u><u>+203.75</u><u>²</u><u>+133.75</u><u>²</u><u>+(-96.25)</u><u>²</u><u>+(-26.25)</u><u>²</u><u>+(-16.25)</u><u>²</u><u>+(36.25)</u><u>²</u>
