Answer:
a=2
Step-by-step explanation:
subtract 10 from both sides
2a^3=26-10
simplify
2a^3=16
Divivde both side by 2
a^2=16/2
simplify
a^3=8
Answer:
d.
A histogram deals with continuous data in ordered columns, while a bar graph deals with discrete data in separate columns.
Step-by-step explanation:
Answer:
c²=√181=13.45, or 13.5
Step-by-step explanation:
The pythagorean theorem is a²+b²=c²
Given this, we will plug in our numbers like this: 9²+10²=c²
9²+10²=181, but we have to find the square root of that.
c²=√181=13.45, or 13.5
I hope this helps!! :)
Answer:
10
4
Step-by-step explanation:
Purple: This makes two trapezoids. A=(a+b)/2 times h
1st = (4+1)/2 x 1 = 2.5
2nd = (4+1)/2 x 3 = 5/2 x 3 = 2.5x3=7.5
Total = 2.5+7.5=10
Green: if you draw a line down the center, you can divide these into two more manageable triangles. A=1/2bh
1st = 1/2x2x2 = 2
2nd = 1/2x2x2 = 2
Total = 2+2=4
Answer:
Option C) 5.62 points
Step-by-step explanation:
We are given the following in the question:
Sample size, n = 20
Sample mean score = 64
Sample standard deviation, s = 12
Degree of freedom =
We have to calculate margin of error for a 95% confidence interval.
Formula for margin of error:
Putting the values, we get,
Thus, the correct answer is
Option C) 5.62 points
