Step-by-step explanation: it is bazillions affter zillions
Answer: 
Step-by-step explanation:
The equation of the line is Slope-intercept form is:
Where "m" is the slope and "b" the y-intercept.
The slopes of perpendicular lines are negative reciprocal.
Then, if the slope of the first line is -3, the slope of the other line must be:
Substitute the point (3,4) into the equation and solve for b:
Then the equation of this line is:
Answer:
Smallest to largest:
1 out of 10, 2/5, 2 out of 3, .75, 7/8
Step-by-step explanation:
An easy way to do this is to write each in decimal form
2/3 = .666666......
2/5 = .4
7/8 = .875
.75
1/10 = .10
Smallest to largest:
1 out of 10, 2/5, 2 out of 3, .75, 7/8
Answer:
83.33% change
Check work:
30 x 0.8333 = 24.999
30 + 24.999 = 54.999 or about 55
Given:
n = 27, sample size
df = n-1 = 26, degrees of freedom
xb = 11.8, sample mean
s = 2.3, sample standard deviation.
Because population statistics are not known, we should use the Student's t-distribution.
At 99% confidence interval, the t-value = 2.779 (from tables).
The confidence interval is
11.8 +/- 2.779*(2.3/√(27)) = 11.8 +/- 1.23 = (10.57, 13.03)
Answer: (10.6, 13.0) to the nearest tenth
