Answer:
Step-by-step explanation:
You need two facts
- The smallest angle is opposite the smallest side
- The name is the letter not making up the line.
RP is the smallest side
Q is the smallest angle
PQ is the next smallest side
R is the next smallest angle
QR is the largest side
P is the greatest angle
<Q <R <P is the correct order from smallest to largest
That's the second one from the top.
Y = 75 - 6d......d = number of days
after 9 days.....d = 9
y = 75 - 6(9)
y = 75 - 54
y = 21....so there are 21 after 9 days
Answer:
c. [70.30, 74.70]
Step-by-step explanation:
Confidence interval is a range of values in which there is a specified probability that the value of a parameter lies within that range.
The confidence interval of a statistical data can be written as.
x+/-zr/√n .......1
Given;
Mean gain x = 72.5 cm
Standard deviation r = 4.5 cm
Number of samples n = 16
Confidence interval = 95%
z (at 95% confidence) = 1.96 (from the table)
Substituting the values we have into equation 1;
72.5 +/- 1.96×4.5/√16
72.5 +/- 2.20 cm
[70.30, 74.70]
Therefore, the 95% confidence interval is
[70.30, 74.70] cm
The graphing of a ratio includes one axis representing part A of the ratio and the other axis representing part B of the ratio. for example, if you have 20 defects per 100 parts of a car, the defects would be represented as part a and the total parts would be represented by part b. These graphs show one part on the left hand and the other on the bottom of the graph, and the graphing of each ratio acts a lot like graphing an equation you would normally see.
Answer
Option (A) is correct .
Reason
The formula for the slope.
As given
Line AB contains (0, 4) and (1, 6) .
put in the slope formula
Slope of the AB is 2.
As given
Line CD contains points (2, 10) and (−1, 4).
put in the slope formula
Slope = 2
Slope of the CD is 2.
As the slope of the AB contains (0, 4) and (1, 6) Line CD contains points (2, 10) and (−1, 4) is 2 .
Therefore the option (A) is correct i.e the lines are parallel because the slopes are the same.
