Answer:
x-1
Step-by-step explanation:
| x-1| x> 1
Since x is greater than x, the absolute value will be positive so we can remove it
x-1
Lets use a number to check
Let x = 4
| 4-1| 4>1
3 which is positive
Answer:
x - 1
Step-by-step explanation:
| x - 1 |
x > 1
x is greater than 1. The absolute value is not needed, since the value inside will only be for positive integers.
x - 1
We can check by plugging x as 2.
2 - 1 = 1 (positive)
2 > 1
find f(-9)

Answer:
The answer for (a)(-5.96, 2.36)(b) -1.8, since the difference is negative, it can be said or determined that the age of the grandfather is older
Step-by-step explanation:
Solution
(a) From the information given,
n = 10, d =-1.8, sd = 5.81
The 95% confidence interval for the population mean difference age is computed as follows:
CI =d ±tα/2,n-1 (sd/√n)
= -1.8±t₀.₀₅/₂,₁₀₋₁ (5.81/√10)
=-1.8± 2.26 (1.84)
= -1.8 ± 4.16
= (-5.96, 2.36)
Now,
There is a 95% confidence that the mean difference in age of maternal grand parents of high school students lies between - 5.96 and 2.36
(b) The age difference is calculated as the age of grand mother minus age of grand father. the point of estimate for the mean difference is as follows:
Xd = XGM - XGF
= 69.8 -71.6
=-1.8
Therefore, since the difference is negative, it can be said or determined that the age of the grandfather is older

Answer:
Step-by-step explanation:
● 5 [ (27/8)^2 ÷ (81/4)^3 ] × 6^4
● 5 [ 27^2/8^2 ÷ 81^3/4^3 ] × 6^4
● 5 [ 27^2/8^2 × 4^3/81^3] × 6^4
● 5 [ 27^2 × 4^3 / 8^2 × 81^3] × 6^4
● 5 [ (3^3)^2 × 4^3 / (4×2)^2 × (9^2)^3]×6^4
● 5 [ 3^6 × 4^3 / 4^2 × 2^2 × 9^2 ×2^3]×6^4
● 5 [ 3^6 × 2^6/2^9 × 3^4 ] × 6^4
● 5 [ 3^2 /2^3] × 6^4
● 5 [3^2 × 6^4 / 2^3]
● 5 [ 3^2 × 2^4×3^4 / 2^3]
● 5 [ 3^7 × 2]
