Answer:
Step-by-step explanation:
Let the two angles be x and y
Then: y = 5x - 6
And x + y = 180° (the of supplementary angle is 180°)
Putting y = 5x - 6
x + 5x - 6 = 180
6x = 180 + 6
6x = 186
x = 186/6
x = 31°
And y = 5x - 6
y = 5(31) - 6
y = 155 - 6
y = 149°
The angles are 31° and 149°
Answer:
.
Step-by-step explanation:
It is given that,
Red marbles = 3
Blue marbles = 7
Orange marbles = 5
Total marbles = 3+7+5 = 15
Probability of getting a red marble is
If a marble is drawn from the bag and not replaced. So remaining marbles is 15-1=14. Now,
Probability of getting an orange marble is
Now,
Therefore, the required probability is .
60 is the answer I hope this helps a lot.
Answer:
Yes.
Step-by-step explanation:
Since he only sampled 50/400, 50 of 400 is 1/8.
7x8=56.
<span>a3 = −11 and an = 2an − 1 − 1
a2 = -11+1 = -10/2 =-5
a4 = </span>2(-11)-1 =-22-1=-23
<span>
a4 = −36 and an = 2 an − 1 − 4
a3 = -36+4 = -32/2=-16
a2 = -16+4=-12/2=-6</span>
