let's say the two numbers are x and x + 9. so we know x + x + 9 = 21, so 2x + 9 = 21. subtract 9 from both dies to get 12 = 2x. divide both sides by 2 to get x = 6. so your two numbers are 6 and 15.
For 11 on the dot plot its only supposed to be 2 dots because u only see two 11’s the mean is 78/15 which equals 5.2 the mode is 5 the range is 11-1 which equals 10
Answer:
Distance = 13
Step-by-step explanation:
Using the distance formula, plug in the two points:
d = sqrt(9-(-3))^2+(-3-2)^2
d = sqrt(12)^2+(-5)^2
d = sqrt144+25
d = sqrt169
d = 13
Answer:
Step-by-step explanation:
x² = 40² + 9²
= 1600 + 81
