Answer: 0.8031
Step-by-step explanation:
Binomial distribution:
For a binomial variable x,
The probability of getting success in x trials = 
, where n = Total trials .
p= Probability of getting success in each trial.
For the given situation , we take x as the number of damaged apple .
Given : The proportion of damaged apples : p=0.15
n= 10
Then, the probability that his sample will contain at least one damaged apple. :-
Hence, the required probability = 0.8031
Answer:
No, 900 grams is 1.98416 Pounds
If a triangle has sides of 7 cm and it is an equilateral you can draw a line right down the middle to form two congruent triangles.
These smaller triangles have a hypotenuse of 7cm and a base of 3.5 cm (7/2)
To work out the height, use Pythagoras’ theorem.
a^2 + b^2 = c^2 where c is the hypotenuse and a and b are the other two sides
7^2 - 3.5^2 = 36.75
Square root answer
= 6.06 cm
That’s the height of the triangle
Area of a triangle is base x height divided by 2
So 7 x 6.06 = 42.43…
/2
= 21.2 cm^2 to one d.p

Answer: ?=Y
Explanation: The letter represents the last letter of the total. For example, 1+1+1+1= 4 (fouR), 3+3+3+3=12(twelvE), therefore 5+5+5+5=20(twentY)
