Answer:
p = 1
Step-by-step explanation:
-6p - 21 = 3p - 12
+6p +6p
-21 = 9p - 12
+12 +12
9 = 9p
//////////
9 9
1 = p
p = 1
Answer:
The original price of the tent was $130,00.
Step-by-step explanation:
The original price of the tent will be called "x". The store increased the value by 25%, so the new value is the original one plus 0.25 of the original one, so the new value is 1.25*x. The costummer paid the increased value less the $10 from the coupon, so we have:
paid = 1.25*x - 10
Since he paid $152.5 for the tent we can compute the original value as shown bellow:
152.5 = 1.25*x - 10
1.25*x = 152.5 + 10
1.25*x = 162.5
x = 162.5/1.25 = 130
The original price of the tent was $130,00.
Answer:
0.0321
Step-by-step explanation:
This can be found by binomial probability distribution as the probability of success is constant. There are a given number of trials. the successive tosses are independent.
Here n= 5
The probability of getting a four in a roll of a die = 1/6
The probability of not getting a four in a roll of a die = 5/6
The probability of getting exactly three 4s in five throws is given by
5C3 (1/6)³ (5/6)² = 10 (0.0046) (0.694)= 0.0321
Only 1 solution : when u calculate it the only answer you get is -1. Hope this helps
