You can think that for every 5 glue sticks, you will have 2 glue bottles. Since 35 means 5×7, then the number of glue sticks will be 2×7 which is 14
3ab * 2ac = 6a^2bc
3ab * 3bc = 9ab^2c
= 6a^2bc + 9ab^2c
So the answer is D
Yes it does mean its the same
Answer:
1. Type I error = 0.0241
2. Power of test = 0.2146
Step-by-step explanation:
1.
Test statistic:
z = (x- µ)/(σ/√n)
= (0.15 - 0.125)/(0.04/√10)
= 0.025/0.0126
= 1.9764
p-value = 1- NORM.S.DIST(1.9764, 1)
= 0.0241
Type I error = 0.0241
2.
If true µ₁ = 0.14,
then Power, (1 - β) is given as;
1 - β = P(X ≥ 0.15 | µ₁ = 0.14)
= P(Z ≥ (0.15 - 0.14)/(0.04/√10) )
= P(Z ≥ 0.79)
= 1 - P(Z < 0.79)
Using excel function :
= 1 - NORM.S.DIST(0.79, 1)
= 1 - 0.7854
= 0.2146
Power of test = 0.2146
The time taken for the person to get to school based on the equation will be 7 minutes.
<h3>How to calculate the time?</h3>
From the information given, the equation is given as:
g(x) = x⁴ - 3x² + 4x - 5
Then, we'll put 2 as x. This will be:
= 2⁴ + 3(2)² + 4(2) - 5
= 16 - 12 + 8 - 5
= 7
Therefore, the time taken for the person to get to school based on the equation will be 7 minutes.
