Answer:
22
Step-by-step explanation:
178 divide by 8 = 22
2300 out of 4500 were chosen
2300 / 4500 = 0.5111
0.51 = 51%
51% is the acceptance rate.
The base fee is 4 dollars, and the thing the at changes is x or the hours so the equation is 4 + 2x equals 12. and to solve for x we have to first subtract both sides by 4, getting 2x equals 8 then we divide both sides by 2 to get x equals 4 or 4 hours
It should be 112.5 pounds because if there are 15 boxes and each box weighs 7.5 pounds, 15 x 7.5 = 112.5
Answer: 15 / 56
Step-by-step explanation:
Number of red checkers = 3
Number of black checkers = 5
Total number of checkers = 8
P(black, then red) = 5/8 × 3/7 = 15/56
We should note that the probability to pick a black checker first will be 5 out of 8. Then, there'll be 7 checkers left and the probability to pick a res checker will be 3/7. We then multiply the probabality of each together.
