Answer:
Solution given:
9x-4=8+7x[Vertically opposite angle]
9x-7x=8+4
2x=12
x=12/2
x=6
:.<u>8</u><u>+</u><u>7</u><u>x</u><u>=</u><u>8</u><u>+</u><u>7</u><u>×</u><u>6</u><u>=</u><u>5</u><u>0</u><u>°</u>
Parallel lines have the same slope. Since our reference line has a slope of -1, so will a line parallel to it. Thus far we have:
y=-x+b, using point (7,1) we can solve for b
1=-7+b
8=b so the parallel line passing through (7,1) is:
y=-x+8
Paul = 36kg
Felix = 18kg
Frank = 22kg
36+18+22=76
Their weight all together is 76kg.
<span>The input of days results in the output of total collected books. On day 1, 8 books were collected. Both inputs for days 2 and 3 have the same output of 13, meaning that no books were collected for day 3. After 5 days, 21 books were collected. The most books were collected on day 5.</span>
Answer:
0.0444 = 4.44% probability that a part chosen at random (from the sample) was defective.
Step-by-step explanation:
Probability of a defective part:
0.04 of 
, that is, coming from A.
0.05 of 
, that is, coming from B. So
0.0444 = 4.44% probability that a part chosen at random (from the sample) was defective.
