140,000 cm³ of plywood is needed to make the prop.
Explanation:
- The dimensions of the required box are 70cm × 40cm × 50cm.
- So we take the length equals 70cm, the width is equal to 40cm and the height is 50cm. The volume of this box is calculated by multiplying the given box's length, its width, and its height. The question does not provide which measurement is which but ultimately the volume will be equal no matter what the case.
- Volume of box = Length × Width × Height = 70cm × 40cm × 50cm = 140,000 cm³.
- So 140,000 cm³ of plywood is needed to make the prop in the play
I think the answer would be 288, i hope this helps
Answer:
we reject H₀
Step-by-step explanation: Se annex
The test is one tail-test (greater than)
Using α = 0,05 (critical value ) from z- table we get
z(c) = 1,64
And Test hypothesis is:
H₀ Null hypothesis μ = μ₀
Hₐ Alternate hypothesis μ > μ₀
Which we need to compare with z(s) = 2,19 (from problem statement)
The annex shows z(c), z(s), rejection and acceptance regions, and as we can see z(s) > z(c) and it is in the rejection region
So base on our drawing we will reject H₀
He earns $44 dollars. he charges $2 dollars for every bag.
The distance between any 2 points P(a,b) and
Q(c,d) in the coordinate plane, is given by the formula:<span>

</span></span>
Using this formula we calculate the distances |PA|, |PB|, |PC|, |PD| and |PE| and compare to 5.
