Step-by-step explanation:
2x + 3y = 6
3y = -2x + 6
divide through by 3
y = (-2/3)x + 6............1
but equation of a straight line is
y = mx + c..............2
compare equation 1&2, m = -2/3 and c = 6
where m = gradient
c = intercept
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>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:
they need 4 buses
60+60+60=180 that does not get you to 196 so you would add 1 more bus
which equals 4 buses
Let's see -
We already know that a number raised to a certain power means repeated multiplication, right? So, all we have to do is multiply 5 × 5 × 5 × 5
436 times! I know, big, right?
This WILL give you a decimal answer and a + sign, so please don't be confused with me!
5 raised to the 436th power is going to give you
= 5.635362925894614e + 304
Crazy, right?

Answer:
14
Step-by-step explanation:
A = 1/2 BH
B = 5H
A = 490
490 = 5/2 * H^2
H = 14
