Answer: 547
Step-by-step explanation: The margin of error formulae is given below as
Margin of error = critical value ×(σ/√n)
Where σ = standard deviation and n is the sample size.
From our question, margin of error = 0.08
Variance is 1.691,
hence σ = √variance = √1.691
= 1.3.
We will be using a z test for our critical value this is because a soft drink manufacturer will always produce drinks more than 30 in numbers.
The critical value for a 85% confidence interval is 1.44.
Hence critical value is 1.44.
By substituting the parameters, we have that
0.08 = 1.44 × 1.3/ √n
0.08 = 1.873/ √n
By cross multiplying
0.08 × √n = 1.873
√n = 1.873/ 0.08
√n = 23.41
n = (23.41)²
n = 547.
2 consecutive odd integers...x and x + 2
x + (x + 2) = 36
2x + 2 = 36 <===
X^2 +3x - 18 is the answer
2,125,764 because every year it is multiplier by three which reaches to 2,125,764
Answer:
The needle palm tree is growing faster.
Step-by-step explanation:
The rate of growth of needle palm tree = 4.35 cm / day
The rate of growth of cabbage palm tree = 1.26 cm /day
From the given data we can clearly see ,
4.35 > 1.26
So the needle palm tree is growing faster.
