1. + and - are inverses as well as × and ÷
2. They are equivalent because x equals -3 in each equation.
3. x-3=6 because x=9 in this equation whereas it equals 6 in all of the other ones
Answer:
The probability of bowling 3 consecutive strikes is 0.3890.
Explanation:
On any given turn, this player has a 73% chance of bowling a strike. Hence:
Probability of bowling a strike = P(S) = 73% = 0.73
We need to find the probability of this player bowling 3 consecutive strikes. This is computed as follows:
Probability of bowling 3 consecutive strikes
= Probability of bowling first strike x Probability of bowling second strike x Probability of bowling third strike
= P(S) x P(S) x P(S)
= 0.73 x 0.73 x 0.73
= 0.3890
Answer:
18-Yes 19-No 20-yes 21- yes
Step-by-step explanation:
18
1 to 4, 5 to 20
Yes, this is correct
WE can multiply 1*5 and 4*5 to get 5 to 20
19
Wrong
3 to 11, 1 to 3 isn't correct
For example, if we were to divide 3 by 3 to get one, 11/3 is 2. (6)
So, no
20
2/3 is 2 to 3
14/21 is 14 to 21
If we multiply 2*7 and 3*7, we get 14 to 21
21 25 to 30 is equal to 35 to 42
They just added 7 to both numbers
if we divide ratio 1 by 5, we get 5:6
if we divide ratio 2 by 7 we get 5 to 6
2 1/4 = 9/4
(9/4)(8/5) = (9/1)(2/5) = 18/5 = 3 3/5 cups
