3 1/2 + 4 5/6
Multiply 3 1/2 by 3/3 so that both fractions have "6" as their bottom number (denominator).
3 1/2 × 3/3 = 3 3/6
So, our new question is this : 3 3/6 + 4 5/6
Basically, when both fractions have the same bottom number (denominator), all you have to do is add the top numbers (numerators) as well as adding the whole numbers. Remember, you always keep the bottom number (denominator) the same when you are adding or subtracting.
Whole number : 3 + 4 = 7
Numerator : 3 + 5 = 8
Denominator : 6
So, our answer is 7 8/6
However, because the top number (numerator) is greater than the bottom number (denominator), you have to make the whole number larger.
So, our answer is 8 2/6
Simplify.
8 1/3

Answer:
The correct option is;
B. With 95 percent confidence, it can be said that the repair cost is between the bounds of the confidence interval
Step-by-step explanation:
Here we have the formula for confidence interval, CI given as follows;

Where:
 = Sample mean = $90.00
 = Sample mean = $90.00
s = Sample standard deviation = $14.00
n = Sample size = 5
t = z value for the confidence level = 2.7764 from z-score relations
Plugging in the values, we have;

Which gives the CI as 72.6167 to 107.38.

Answer:
140°
Step-by-step explanation:
Three angle are labeled below the acre. The smallest angle is 3/8 as large as the 160 angle. Find the value of angle a
The value of the smallest angle is given as:
= 3/8 of the 160 angle
=3/8 × 160°
= 60°
The sum of the total angle = 360°
Hence:
360° = 60° + 160° + a
a = 360° - (60° + 160°)
a = 360° - 220°
a = 140°
Therefore, a = 140°
