Your question evokes several thoughts. Here are two of them:. 1). It takes 3 points not all on the same line to define a plane. 2). Two points ALWAYS lie on the same line.
I believe his net worth would be $21,310
if you add all of it together but subtract his debts that’s your answer i’m pretty sure. hope it helps!
Given:
Ten People
5 people = 30 years old
3 people = 32 years old
1 person = 31 years old
1 person = 65 years old
We need to arrange the ages in order from least to greatest.
30, 30, 30, 30, 30, 31, 32, 32, 32, 65
65 is the outlier.
A.) mean age without the outlier. count of the numbers : 9
5 x 30 = 150
1 x 31 = 31
3 x 32 =<u> 96</u>
total age 277
÷ # of pax<u> 9</u>
mean 30.77 round to the nearest tenth 30.80
b.) Standard deviation:
We need to calculate variance first:
5 pax : 30 - 30.80 = - 0.80 ⇒ -0.80² = 0.64 * 5pax = 3.20
1 pax : 31 - 30.80 = 0.20 ⇒ 0.20² = 0.04 * 1pax = 0.04
3 pax : 32 - 30.80 = 1.20 ⇒ 1.20² = 1.44 * 3 pax = 4.32
Variance : (3.20 + 0.04 + 4.32) / 9 pax = 7.56 / 9 = 0.84
Standard deviation is simply the square root of the variance.
Standard deviation = √0.84 = 0.916
0.916 round to nearest hundredths is 0.92
0.916 round to nearest tenths is 0.90
Answer: g(x) is the image of f(x)
Step-by-step explanation:
multiplying the x value by -1 means you reflect that point across y-axis, therefore, g(x) is the reflection of f(x) across y-axis.
The Answer is
D) 31
Because 9x+13,
9(2)+13,
18+13,
31
