7.2(2.8r-4.5s)+9.34r -1.25s
=20.16r - 32.4 +9.34r -1.25s
=29.5r - 33.65s
So the answer is A
hope I can help u
There is some inforrmation that is missing in this question. It should read:
<span><span>A container holds 50 electronic components, of which 10 are defective. If 6 components are drawn at random from the container, the probability that at least 4 are not defective is . If 8 components are drawn at random from the container, the probability that exactly 3 of them are defective is .
</span><u>Answers</u>
<span>Part 1. 0.02
Part 2. </span></span>0.0375<span><span>
</span><u>Explanation</u>
The probability is a chance of an event happening. It is calculated as;
probability = (Number of favourable outcome)/(Number of available outcome)
Part 1
6 are chosen at random. If 4 are not defective, then 2 are defective.
P(at least 4 are not defective) = 4/40 </span>× 2/10
= 1/10 ×1/5
= 1/50
= 0.02
Part 2
8 are chosen at random. If 3 are defective, the 5 are not defective.
P(3 are defective) = 3/40 × 5/10
= 15/400
= 3/80
= 0.0375
Answer:
I think it is 3.
Step-by-step explanation:
333+456=300+30+3=400+50+6=700+80+9=789
4³=64
5²=25
9³=729
64+25+729=
60+4+20+5+700+20+9=
100+18+700=

Answer:
A. Nothing, Paul is correct
Step-by-step explanation:
- Tangent to a circle is a line that touches the circle at one point. At the point of contact, tangent to a circle is always perpendicular to the radius.
- If two tangents are drawn from a common external point to a circle, then the two tangents have equal tangent segments.
- Tangent segment means line joining to the external point and the point of contact to the circle.
