Answer: 1/2, 5/8, 7/10
Step-by-step explanation:
7/10 = 0.7
1/2 = 0.5
5/8 = 0.625
From least to greatest:
1/2, 5/8, 7/10
Answer:
Well first of all, that isn't an equation, I wil however interpret it as best as I can.
x = 25 + 5y
Step-by-step explanation:
x/5 - 5 - y for x, so, x/5 - 5 - y = 0.
Add 5 and y to both sides.x/5 = 5+ y, multiple both sides by 5.
x = 25 + 5y
If about 20% of British children are deficient in vitamin and doctors test a group of elementary school children, the probability that the first vitamin d-deficient child is the 8th one tested is 4.19% determined using geometric distribution formula.
In probability and statistics, geometric distribution refers to the probability that first success would occurs after n number of trials and is given by:
P(X)=q^(x-1)p
Where p is the probability of success and q is (1-p)
In this case,
p=probability of children deficient in vitamin= 0.2
q= probability of children not deficient in vitamin= 0.8
Hence,
P(8)=0.8^(8-1)*0.2= 0.0419
Hence, the probability that 8th child is deficient is 4.19%

Answer:
6.1
Step-by-step explanation:
Surface area of the room = 2(lw + hl + hw)
Where,
l = length = 7 m
w = width = 4 m
h = height = 3 m
Surface area of the room = 2(lw + hl + hw)
= 2(7*4 + 3*7 + 3*4)
= 2(28 + 21 + 12)
= 2(61)
= 122 m²
A 4-L can of paint covers 40 m²
Number of 4-L can of paint needed for 1 coat = 122 m² / 40 m²
= 3.05 4-L can of paint
The walls need 2 coats of paint
Number of 4-L can of paint needed for 2 coats = Number of 4-L can of paint needed for 1 coat × 2
= 3.05 × 2
= 6.1 4-L can of paint
