If she continues to throw darts 75 more times, she could predict to hit the

bull's-eye 15 times.</h2>
Step-by-step explanation:
Shay found that she hit the bull's-eye when throwing darts times = .
In five times, she will hit the dart once.
If she continues to throw darts 75 more times,
the probability that she will hit the bull's eye = (75) = 15 times.
If she continues to throw darts 75 more times, she could predict to hit the
bull's-eye 15 times.
To determine the number of possible arrangements for 6 out of 8, we should use combinations. That is
ₐC₆ = 8!/(6!2!)
Answer: b. Combination
This is tricky because we are given the interest rate for the year but the problem is figureing the interest for 6 months or 1/2 year. We will have to double the difference before solving for the yearly interest.
572.60 - 560.00 = 12.60 interest added for 6 months x 2 = 25.20 for 12 months
(This problem assumes the interest will stay the same the next 6 months)
We need to find what percent 25.20 is to our original balance.
25.20/560 = x / 100
2520 = 560x
x = 4.5 percent interest
Check .045 x 560.00 = 25.20 interest in one year (or 12.60 in 6 months)
Since, the population of a town increased from 5,400 to 6,000 people. We have to calculate the percent of increase.
Firstly, we will find the difference of 6000 and 5400,
6000-5400 = 600
Secondly, we will divide 600 by 5400,
So, = 0.1111
Thirdly, we will multiply 0.1111 by 100%
= 11.11 %
Therefore, there is 11.11% increase in the population of a town.
Answer:
x > 7
Step-by-step explanation:
0.8 - 3.2x < -2 - 2.8x
Add 2.8x to both sides.
0.8 - 0.4x < -2
Subtract 0.8 from both sides.
-0.4x < -2.8
Divide both sides by -0.4. Remember that when you multiply or divide both sides of an inequality by a negative number, the inequality symbol changes direction.
x > 7
