Twenty five subtracted by six tenths times "x"
Answer:
20%
Step-by-step explanation:
The events are independent (the probability of one does not affect the probability of the other). Therefore:
P(A and B) = P(A) P(B)
P(A and B) = (0.50) (0.40)
P(A and B) = 0.20
Complete question :
The Daily Info charges a fee $650 of plus $80 per week to run an ad. The People's Paper charges $145 per week. Write an inequality to represent the number of weeks an ad must run for the total cost at the Daily Info to be less expensive than the cost at the People's Paper. Let w be the number of weeks the ad runs in the paper
Answer:
650 + 80w < 145w
Step-by-step explanation:
Given that :
Number of weeks ad will run = w
Daily Info total cost :
650 + 80w
The People's Paper total cost:
145w
Number of weeks ad should run For cost at daily info to be less expensive than peoples choice';
Daily Info total cost < people's choice
650 + 80w < 145w
650 < 145w - 80w
650 < 65w
650/65 < 65w / 65
10 < w
w > 10
The total number of marbles = 6 + 5 + 2 = 13 marbles
Orange= 2 marbles
The probability of getting the first marble out of the hat is
2 / 13
The probability of getting the second marble out of the hat is
1 / 12 The total has been reduced by one and the number of orange marbles has been reduced by one.
2/13 * 1/12 = 2 / 156 = 1/78
