Answer:
35
Step-by-step explanation:
All angles of a triangle add up to 180 degrees, so you can add the other two angles, then subtract by 180.
Use the estimate but that should be more than the exact price
No I don’t understand ur questions if u could rephrase them so I could answer
Answer:P(BBR) = 1/2 × 25/51 × 26/50 = 13/102 if cards are not replaced.
P(RBB) = 1/2 × 26/51 × 25/50 (simplified 1/2) = 13/102
P(BRB) = 1/2 × 26/51 ×25/50 (simplified 1/2) = 13/102
Step-by-step explanation: P(B) at first step is 26 cards out of a possible 52 therefore 26/52 (or simplified 1/2). We then have 25 black cards left out of a possible 51 therefore 25/51. The final card then has to be red to meet the criteria, we have 26 red cards still out of a possible 50 therefore 26/50.
This would be an example of binomial probability as at each step there are only 2 options R or B.
Answer:
Katie will have 7 dollars left over.
Step-by-step explanation:
100
She buys a book so subtract 23 from 100.
100-23= 77
Katie has 77 dollars and wants to donate $10 to as much charities. 10 can go into 77, 7 times, which means she can only donate to 7 charities in $10.
