The probability that there'll be no defective will be 0.504.
<h3>How to calculate the probability?</h3>
Probability of A being defective = 0.2.
Probability of B being defective = 0.1
Probability of C being defective = 0.3.
The probability that there will be no defective will be:
= (1 - 0.2) × (1 - 0.1) × (1 - 0.3)
= 0.8 × 0.9 × 0.7
= 0.504
The probability that there'll be no defect is 0.504.
The probability that there'll be at least two defective part will be:
= (0.2 × 0.1) + (0.2 × 0.3) + (0.1 × 0.3)
= 0.02 + 0.06 + 0.03
= 0.11
The probability that there'll be at least two defects is 0.11.

Hello,
A:
2x²-7x-4=0
==>2x²-8x+x-4=0
==>2x(x-4)+1(x-4)=0
==>(x-4)(2x+1)=0
==>(x=4) or (x=-1/2)
B: where is the sign "=" !!!!!!!!!!!!!!!!!!
81x^-1=(9x²+1)(3x+1)(3x-1) I can not go any further.
C)
2x²-32=0
==>x²-16=0
==>(x+4)(x-4)0
==>x=-4 or x=4
D:
where is the sign "="!!!!!!!!!!!!!!!!!!!!!!!!
x^2-7x+12=(x-4)(x-3) but I can not go ant further....
Answer:
4 days
Step-by-step explanation:
9 months/6 months = 6 days /x days
9/6 = 6/x
x = 4
Answer:
2x² + 4x + 3 = 0
Step-by-step explanation:
The function is said to be quadratic if it has highest degree = 2.
Further, The standard form of Quadratic Equation is:
ax² + bx + c = 0
where, a ≠ 0
a, b and c are constants
and x is unknown variable.
Thus, The Standard form of given Quadratic Equation is 2x² + 4x + 3 = 0
Answer:
Step-by-step explanation 10 + 2.50d = 850
David starts with $10 and each day he earns $2.50. The d represents a variable and can be any number.
To find d you must solve the equation.
10 + 2.50d = 850
2.50d = 840 (subtract 10 from 850)
d = 336 (divide 840 by 2.50)
It will take David 336 days to save $850.
