Step-by-step explanation:
Because vertical angles have equal measure, angle CPB = 90 degrees. By extension, angle CPQ + angle QPB = 90 degrees
So 2x+4x+12=90
6x+12=90
6x=78
x=13
2)
Okay so because the right side is two times the length and width of the left side, we need to divide 20 and 14 by 2 which gives us 10 and 7. That means x+2 = 10 so we need to subtract 2 from each side which gives you 8. Therefore, x = 8.
20/2 = 10
10 - 2 = 8
x = 8
Answer:
The greatest four consecutive numbers whose sum is less than 1,000 are 248, 249, 250, and 251.
Step-by-step explanation:
Let x be the smallest integer. Then:
x + x + 1 + x + 2 + x + 3 < 1,000
4x + 6 < 1,000
2x + 3 < 500
2x < 497
x < 248.5, so x = 248
So we have the integers 248, 249, 250, and 251.
Answer:
0.5
Step-by-step explanation:
P(C|Y) = P(C^Y)/P(Y)
= 15/30
= 0.5
