The price of a holiday was decreased by 12 percent to 600 . What was the price before the decrease?
Deffense [45]

Price before decrease = x

If price before decrease is 100, then price after decrease = 100- 12 = 88

100:88 = x:600

100/88=x/600

100/88 ×600 = x

681.82 =x

Price before decrease =681.82

The weight of adults Male beagles are normally distributed, with a mean of 25 pounds and a standard deviation of 4 pounds.
a_sh-v [17]

Answer:

There is a 95.6% chance that the weight will fall within this range.

Step-by-step explanation:

This is because the extremes that are given are roughly two standard deviations from the mean. To be outside of that, there is only 2.2% likelihood to be higher and another 2.2% to be lower. When we subtract these two from 100%, we get our probability.

100% - 2.2% - 2.2% = 95.6%
