Answer:
x = 16 y= 16√3
Step-by-step explanation:
we know that a angle is 60 degrees. Thanks to this information we can say that x is half the hypothenuse, so is value is 16.
y can be express as √3/2 x 32 = 16√3
Unit rate in this case would be pages per minute so divide (5/8)pages÷(2/3)minute.
Dividing a fraction can be done as multiplying by the reciprocal.
(5/8)·(3/2)=15/16pages per minute or 0.9375 pages/min.
Answer: r = 3
Step-by-step explanation:
Step 1: Cross-multiply.
2r = 12/18
(2)*(18)=12*r
36=12r
Step 2: Flip the equation.
12r=36
Step 3: Divide both sides by 12.
12r/12 = 36/12
r = 3
Answer:
70.56
Step-by-step explanation:
The variance is the standard deviation squared.
σ² = (8.4)² = 70.56
Answer:
66
Step-by-step explanation:
you have to find the median, and then find the median within the second half of the median
Median : 61
Now, look at 61, and look at 74. What is the median of those numbers in this set?
Q₂ = 66
