Answer:

22.11% < 25%

Step-by-step explanation:

In the last week, 1221 people went to the beach and this week 951 people went to the beach.

So, the reduction in the number of people went to the beach this week will be (1221 - 951) = 270.

Therefore, the percentage reduction in the number of people went to the beach this week will be \frac{270 \times 100}{1221} =22.11 %.

So, the percent reduction is less than 25%. (Answer)

Answer:

9/10

30%

Step-by-step explanation:

Only in trial number 4, there is just one correct answer. In all other 9 trials at least 2 answers were correct. So the probability is 9 out of 10 trials give a winning outcome, in short, 9/10.

Giving birth to three males first, is true in 3 out of 10 trials. You can count the total numbers of Y's in the last column.

So 3/10 which is 0.3 which is the same as 30%.

Given: AABC, AC = 5<br> m C = 90°<br> m A= 22°<br> Find: Perimeter of AABC<br> A<br> C<br> B
Leto [7]

9514 1404 393

Answer:

  perimeter ≈ 12.4 units

Step-by-step explanation:

The side adjacent to the angle is given. The relationships useful for the other two sides are ...

  Tan = Opposite/Adjacent

  Cos = Adjacent/Hypotenuse

From these, we have ...

  opposite = 5·tan(22°) ≈ 2.02

  hypotenuse = 5/cos(22°) ≈ 5.39

Then the perimeter is ...

  P = a + b + c = 2.02 + 5 + 5.39 = 12.41

The perimeter of ∆ABC is about 12.4 units.
