Answer:
P = 57/1105
P = 0.052
Step-by-step explanation:
Given:
Total number of dummy tickets = 20
Total number of tickets with value = 10 + 10 + 12 = 32
Total number of tickets in the box = 20 + 32 = 52
The probability of picking 3 tickets randomly from the box without replacement and the three are dummy (with no value) is;
P = 20/52 × 19/51 × 18/50
(As each one is picked it reduces the total number of tickets and also the number of dummy tickets by one)
P = 57/1105
P = 0.052
Answer:
Step-by-step explanation:
The question you should be asking yourself is, "80% of how many doctors is 240?" Algebraically, 80% is .8, "of" is multiplying, "how many doctors" is our unknown, and "is" means equals. Putting that all together:
.8x = 240 so
x = 300
Answer:
∠ A ≈ 44.42°
Step-by-step explanation:
Using the cosine ratio in the right triangle
cos A = = = , then
∠ A = ( ) ≈ 44.42° ( to the nearest hundredth )
The answer is B the lowest y term is -6 and the highest is 9 therefore the answer is B
So the rounded weights would be 3, 5, 2, 6, and 11, as when you round, you look at the number to the right of the one you want to round to. If it's 5 or larger, you add one to the spot you're rounding to, and make the rest of the numbers after into zeroes. If it's below 5, just change the ones after the one you want to round to into zeroes and don't add one.
Then for the estimating of the weight, you would add them together. 3+5+2+6+11. That would equal 27, so the estimate weight is 27 grams.
