Answer:
9 because 3^3 is 9
Step-by-step explanation:
And since it's in the ones place nothing can stop it from being 9 since the tens or hundreds place don't contribute to the ones place.
Answer: i said this first. I hope this helps.
2x = 5
x = 5/2
y + 1.8 = 14.7
Y = 12.9
6 = 1/2z
z = 12
3 1/4 = 1/2 + w
w = 11/4= 2.75
2.5t = 10
t=4
Answer:
- 0.196 < μ < +0.196
Step-by-step explanation:
n = 100
σ = 1
X bar (x⁻) = 0
1 - ∝ =95%
μ = ?
= X bar (x⁻) ± Z ∝/₂ * σ/√n
Finding ∝:
To find ∝, we will convert the confidence interval i.e. 95% into decimal by dividing it with 100 and subtracting it from 1.
1 - ∝ = 95%
1 - ∝ = 95/100
1 - ∝ = 0.95
∝ = 1 - 0.95
∝ = 0.05 -----(1)
We have to calculate ∝/2 so dividing both sides of (1) with 2
∝/2 = 0.05/2
∝/2 = 0.025
We will find the value of 0.025 in z-table. The value is:
Z ∝/2 = 1.96
For further calculations, we will use the value of Z∝/2.
Putting all values in the formula.
= 0 ± 1.96 * 1 / √100
We can also write this in the following form:
0 - 1.96/ √100 < μ < 0 + 1.96 / √100
- 1.96 / 10 < μ < 1.96 / 10 ∴ √100 = 10
- 0.196 < μ < + 0.196
