i^85 = √-1^85 = (-1)^42 times i = i
Please Help!!! Calculate the interquartile range for this set of data: {34, 47, 1, 15, 57, 24, 20, 11, 19, 50, 28, 37}
allsm [11]
Let's put it in order.
1, 11, 15, 19, 20, 24, 28, 34, 37, 47, 50, 57
Let's split it in half.
1, 11, 15, 19, 20, 24║28, 34, 37, 47, 50, 57
17 42
42-17
25
The IQR is C) 25.
Answer:
B) 645cm²
The approximate surface area of this prism is 645cm².
Suppose my daughter is x years old now, my father is 13x years old
next year my daughter will be x+1 years old, my father will be 13x+1, which is also 11(x+1)
so 13x+1=11(x+1)
13x+1=11x+11
2x+10
x=5
father is 13x=65 years old now.
The answer is -3
You use the formula y1-y2
———
x1-x2
-1 and 8 are your y’s
1 and -2 are your x’s
Your equation should look like this
-1-8 -9
—— = —— = -3
1-(-2) 3
I plugged the y’s and x’s into the formula.
I hope this helps!!
