Answer:
<h2>∗ = 0.4x³</h2>
Step-by-step
We have :
2×(0,4)×15=12
(0,4)^2=0,16
(15y + ∗)^2 = 225y² + 12x³y + 0.16x⁶
= (15y)² + 2×(15y)×(0.4x³) + (0.4x³)²
then
∗ = 0.4x³
Answer: It is divisible
Step-by-step explanation:
Its divisible because when you divide 656250 by 10 you get 65625. Its divisible because its a whole number and not a decimal.
17%
17/100 = .17
Which is 17%
Answer: 
Step-by-step explanation:
Given : sample size : n= 51
sample standard deviation : s= 0.46
Significance level : 
Using chi-square distribution, the critical values will be :
Confidence interval for population standard deviation (
) :
Substitute all the values , we get
Hence, the 95% two-sided confidence interval for σ :
Answer:
Step-by-step explanation:
The points/decimals do not line up, therefore you need to correctly line them up so it should be.
2.80
+ 1.64
which would be 4.24
