Answer:
34,000
179,400
39,900
Step-by-step explanation:
In the number 33,762, the 3 is in the thousands place, so we look to the number behind it. If it is less than 5, we round down, and if it is more than 5 we round up.
Since 7 is more than 5, we round up, so our rounded number would be
34,000
Let’s use this logic for the rest of these numbers
179,406
4 is in the hundreds
Previous number in 0 which is less than 5, so it rounds down
179,400
39,994
9 is in the tens place
Previous number is 4 which is less than 5, so it rounds down
39,990
Answer:
P (arts) = 0.25
P (psychology) = 0.25
P (geology) = 0.5
Step-by-step explanation:
Let the probability of choosing art = x
As given that she is equally likely to choose art or psychology and twice as likely to choose geology.
So,
P (arts) = x = P (psychology)
P (geology) = 2x
The sum of the probability = 1
So,
P (arts) + (psychology) + P (geology) = 1
x + x + 2x = 1
<u>x = 0.25</u>
<u>P (arts) = x = 0.25</u>
<u>P (psychology) = x = 0.25</u>
<u>P (geology) = 2x = 2*0.25 = 0.5</u>
You had mistakes, so I did all of them.
9) -6(1 + 11b) = -6 - 66b
10) -10(a - 5) = -10a + 50
11) -3(1 + 2v) = -3 - 6v
12)-4(3x + 2) = -12x - 8
13) (3 - 7k)*-2 = -2 * (3 - 7k) = -6 + 14k
14) -20(8x + 20) = -160x - 400
15) (7 + 19b)*-15 = -15(7 + 19b) = -105 - 285b
16) (x + 1) * 14 = 14(x + 1) = 14x + 14
