Answer:
c) The golf ball will travel 260.8 yards.
d) Hence the residual is 4.2 yards.
Step-by-step explanation:
c) y' = 2.8333x - 22.4967
Now the golf ball will travel 
= 260.8 yards
here y'= 260.8 yards.
d) The residual is : y - y' = 265 - 260.8 = 4.2 yards.
So, we need to know what the unit rate. Basically, how many miles in 1 hour is what we are looking for. To do this, we must use the data given. Let's do 2 hours. So, we have to divide 2 hours by 36 miles. 36/2 is 18. So, 18 miles per hour is our unit rate. Now, we need to find how many miles in 8 hours. So, we need to multiply 18 miles (because that's 1 hour) by the number of hours we need, which is 8 in this case. So, 18*8 is equal to 144. So, 144 miles is the distance traveled in 8 hours. Hope this helped!

The interest that Marcos will get is 50000.
<h3>How to calculate the interest?</h3>
The following can be deduced from the information given:
Principal = 50000
Interest rate = 12.5%
Time = 8 years
The simple interest will be:
= (PRT/100)
= (50000 × 12.5 × 8)/100
= 50000
The amount that will be obtained after 8 years will be:
= Principal + Interest
= 50000 + 50000
= 10000

Answer:
29.5+/-1.11
= ( 28.39, 30.61)
Therefore, the 90% confidence interval (a,b) =( 28.39, 30.61)
Step-by-step explanation:
Confidence interval can be defined as a range of values so defined that there is a specified probability that the value of a parameter lies within it.
The confidence interval of a statistical data can be written as.
x+/-zr/√n
Given that;
Mean x = 29.5
Standard deviation r = 5.2
Number of samples n = 59
Confidence interval = 90%
z-value (at 90% confidence) = 1.645
Substituting the values we have;
29.5+/-1.645(5.2/√59)
29.5+/-1.645(0.676982337100)
29.5+/-1.113635944529
29.5+/-1.11
= ( 28.39, 30.61)
Therefore, the 90% confidence interval (a,b) =( 28.39, 30.61)
