Answer:
619.5cm2
Step-by-step explanation:
Based on what you defined as the parallel sides been 26cm and 33cm and the height been 21cm.
Hence the are of trapezium is half sum of the parallel sides × height.
Expressed mathematically we have:
1/2( 26 +33) × 21 = 1/2 ( 59) × 21 = (59×21)/2= 619.5cm2
For cooking "The Great Cheesecake", a good chef need 2 kilos of flour and 3 kilos of cheese, more talent and a bunch of joy.
<span>If you needed to triple the recipe, you'll need 6 kilos of flour and 9 kilos of cheese, but the rate wouldn't change because:

Answer:
Evaluate.
Step-by-step explanation:
If you attempt to do the equation 
, you will get a very long and complicated answer (which is 2.2233078e+21), so I am assuming that is not the question.
If you were to do 
, you would get a more rational answer of 62.566.
If you would comment on this post or be more specific on what exactly the question aims to ask, that would be a huge help. :)
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
