Answer:
Answer: The mean increases by 3
Step-by-step explanation:
The original data set is
{50, 76, 78, 79, 79, 80, 81, 82, 82, 83}
The outlier is 50 because it is not near the group of values from 76 to 83 which is where the main cluster is.
The original mean is M = (50+76+78+79+79+80+81+82+82+83)/10 = 77
If we take out the outlier 50, the new mean is N = (76+78+79+79+80+81+82+82+83)/9 = 80
So in summary so far
old mean = M = 77
new mean = N = 80
The difference in values is N-M = 80-77 = 3
So that's why the mean increases by 3
Answer:
11 years approx
Step-by-step explanation:
Given data
P=$1000
A=2000
R=6.5%
T= ?
Calculate time, solve for t
t = ln(A/P) / r
substitute
t=ln(2000/1000)/0.065
t=ln(2)/0.065
t=0.693/0.065
t=10.66
Hence the time is 11 years approx
We have that
x²<span> − 2x − 3 = 0
Step 1
</span>isolate the variable terms
<span>x² - 2x = 3
</span>Step 2
complete the square
<span>x² - 2x + 1² = 3 + 1² </span>
<span>(x-1)² = 4
</span>
the answer is the option (x-1)² = 4
Answer:
The answer would be G.
Step-by-step explanation.
To get your answer, you have to pick two points. Ex: (0,4) (4,1)
Put them into the slop equation: slope= y2-y1/x2-x1
slope:1-4/4-0= -3/4
Volume of the cylinder is 100 in³.
Step-by-step explanation:
- Step 1: Calculate the volume of the cylinder using the formula V = πr²h
⇒ V = 3.14 × 1.5² × 9 = 63.585 = 100 in³ (rounding off to nearest 100th)
