55h + 40 = 190.
55h = 150.
h = 2.73
901- whole number
900.5- nearest tenth
7.
a.
5×8=40
5+3=8
8+9=17
8×17=136
40/136 = 0.29
29%
This answer is correct because you divide the area of the patio by the area of all and it gives you the percent taken by the patio.Hope it help.
b. is to find the perimeter
If there were just one question, then the probability of guessing correctly would be 1/3.
Since all the answers are independent (the answer to one question has no bearing on the answers to the others), then this is the case with each question, so the chances of guessing all answers correctly is 1/3 × 1/3 × 1/3 = 1/27. Independent choices are linked by multiplication.
To have exactly 2 answers correct, we have to think of which one is wrong: there are 3 questions and any single one could be wrong. The probability that the first question is wrong is 2/3. And we know that the probabilities of the other two being right is 1/3 each, so the probability of just the first question being wrong and the others right is 2/3 × 1/3 × 1/3 = 2/27. But this is just one of the three cases: 1/3 × 2/3 × 1/3 and 1/3 × 1/3 × 2/3 also both equal 2/27 each. So here we add the cases together: 2/27 + 2/27 + 2/27 = 6/27 = 2/9. So the answer to part (a) of your question is 2/9.
To solve (b) Consider that (b) is the same as (a) with "all answers right" added in. So you can simply add answer (a) to the chance of guessing all answers correctly.
To solve (c) it might help you to think of the equivalent problem: what is the probability of getting 0 correct plus the probability of getting 1 correct?
Answer:
Step-by-step explanation:
Remark
Two results are divisible by 5.
The two are 5 and 10.
There are 36 possible outcomes when throwing 2 dice
Five
You can throw a 5 four different ways
4 - 1
1 - 4
2 - 3
3 - 2
Probability: 4/36
Ten
Ten can be thrown 3 different ways
5 - 5
6 - 4
4- 6
Probability : 3/36
Answer
The probability of a 5 or a 10 = 4/36 + 3/36 = 7/36
