Answer:
The answer is 154.8 ml
Step-by-step explanation:
In this question, the amount of pure acid is 18% of the total solution, that is, 18% of 860 milliliters. So
0.18*860 = 154.8 ml
The answer is 154.8 ml

Answer:
a) 0.2182
b) 0.0691
c) 0.9309
Step-by-step explanation:
Binomial probability distribution
The binomial probability is the probability of exactly b successes on n repeated trials, and B can only have two outcomes.
In which is the number of different combinations of b objects from a set of n elements, given by the following formula.
And p is the probability of B happening.
In this problem we have that:
Bin(20,0.2).
This means that
(a) P(B=4).
(b) P(B≤1).
(c) P(B>1).
Either B is less than or equal to 1, or B is larger than 1. The sum of the probabilities of these events is decimal 1. So
We have that, from b),
So
Answer:
(1 ) Inner curved surface area of the well is 109.9 sq. meters.
(2) The cost of plastering the total curved surface area is 4396.
Step-by-step explanation:
The inner diameter = 3.5 m
Depth of the well = 10 m
Now, Diameter = 2 x Radius
⇒R = D/ 2 = 3.5/2 = 1.75
or, the inner radius of the well = 1.75 m
CURVED SURFACE AREA of cylinder = 2πr h
⇒The inner curved surface area = 2πr h = 2 ( 3.14) (1.75)(10)
= 109 sq. meters
Hence, the inner curved surface area of the well is 109.9 sq. meters.
Now, the cost of plastering the curved area is 40 per sq meters
So, the cost of total plastering total area = 109.9 x(Cost per meter sq.)
= 109.9 x (40)
= 4396
Hence, the cost of plastering the total curved surface area is 4396.
