23/4 miles is as much as 5 3/4 miles. We can also write it as a decimal, because 5 3/4 = 5,75 miles.
If Ammar hikes 5,75 miles in 1 1/4 hour, then we need to find out what distance does he hike in 1/4 hour (15 minutes). To do that we can just divide 5,75 by 5 (because dividing 1 1/4 by 5 will give us 1/4 we're looking for).
5,75 / 5 = 1,15
It means that in one hour Ammar hikes 5,75 - 1,15 = 4,6 miles.
We can also write it as a fraction:
4,6 = 4 6/10 = 4 3/5 = 23/5 miles
Just pick whichever form you like :)
Δ=88
1) Using the Quadratic Equation to Solve
3x²-8x+1=3
3x²-8x+1-3=3-3
3x² -8x -2=0
2)Let's find the discriminant
Δ= (-8)²-4(3)(-2)
Δ=64 -4(3)(-2)
Δ=88

Answer: 0.9746
Step-by-step explanation:
Given : A normally distributed population has a mean of 250 pounds and a standard deviation of 10 pounds.
i.e. 
Sample size : n= 20
Let 
sample mean values.
Then, the probability that this sample will have a mean value between 245 and 255 be
Hence , the probability that this sample will have a mean value between 245 and 255 is 0.9746 .
Answer:
27,000,00
Step-by-step explanation:
The Interest rate is 5% and the borrowed money is $20m. You have to multiply $20m by 5%, which gives you 1m. Then for each year, you must add the $1m to the overall money($20m), meaning you have to add $1m dollars to $20m for 7 years. After the 7 years, there are $7m for interest, and in addition to that, you must add it to $20m. Therefore, overall, Antony would have to pay $27m after 7 years.
