Answer: 38760
Step-by-step explanation:
Given : The number of employees in the company = 20
The number of employees will be selected by company owner to give bonus = 6
We know that the combination of n things taking r at a time is given by :-

Then, the number of different sets of employees could receive bonuses is given by :-

Hence, the number of different sets of employees could receive bonuses is 38760.
The formula for z-score is:
z-score = (X – μ) / σ
where,
X = sample
μ = mean =
1001
σ = standard
deviation = 6
Since we are
looking for volumes less than 1001 mL, let us use 1000.5 mL for X.
z-score =
(1000.5 – 1001) / 6
z-score =
-0.083
Referring to
the standard distribution table for z-test, this corresponds to:
p = 0.4681
<span>So 46.81% of
the bottles are less than 1001 mL.</span>

Answer:
6
Step-by-step explanation:
We have to use Pythagoras' identity twice to find y
The square on the hypotenuse is equal to the sum of the squares on the other two sides.
In right triangle MUT to find TU
TU² + 3² = 6², that is
TU² + 9 = 36 ( subtract 9 from both sides )
TU = 27 ( take the square root of both sides )
TU =
=
= 3
In right triangle NUT to find y
y² = 9² + (3
)² = 81 + 27 = 108 ( take the square root of both sides )
y =
=
= 6
Answer:
3a, 13cm 5, 1:200
Step-by-step explanation:
In the question 3 you just have to divide all of those numbers with that 5000, maybe also make them cm so it makes more sense. So 650m = 65000cm:5000= 13cm
then for the question 5, make the km to cm, so 4.2km would be 420000cm. Then you have to divide that 420000cm with the 21 cm, so 420000:21= 200. Then the scale should be 1:200
I had difficulties with these as well. If you need extra help with the task 3 please pm me :)
