Answer:
The measure of the angle NET is 65 degrees (choice #2)
Step-by-step explanation:
Because ET is tangent, <NTE is 90 degrees. Since we are given <TNG=25 degrees, we can use the fact that the sum of the angles in the triangle ENT is 180 degrees to calculate the remaining <NET:
<NET = 180 - 90 - 25 = 65 degrees
Answer:
π m
Step-by-step explanation:
Arc length = 2πr
where r = radius and 0 = central angle
The given radius is 4m and the given central angle is 45°
Thus, arc length = 2π4
* simplify *
( note when simplifying we leave our answer in terms of π as the answer choices do. )
2 * 4 = 8
arc length = 1π
Hence, arc length = 1π or just π
Answer:
3 gallons.
Step-by-step explanation:
If you add three gallons of water to 1 gallon of antifreeze, then there are 4 gallons total. That means that 1/4 of the solution is antifreeze, and 1/4 is equal to 25%.
A- Associative Property of Multiplication
Answer:
Given that The data to represent average test scores for a class of 16 students includes an outlier value of 78.
We can find sum of all 16 test scores = 84(16) = 1344
Outlier found = 78
If outlier is removed new sum = 1344-78 = 1266
Number of entries without outlier = 15
New average = 1266/12 =84.4
We find that average of new data increases.
Also whenever we remove outlier std deviation also would be reduced.
