Example: 4 x 4 = 16
3 x 4 = 12
The correct answer is letter D, Region D contains the solution for the system of inequalities.
Answer:
The mean score for all students on the quiz was 86.
Step-by-step explanation:
This question is solved by a weighed average.
To find the weighed average, we add the values multiplied by their weight, and after that we divide by the sum of weights.
In this problem, we have that:
Mr. Spears had 20 students in his class with a mean score of 80.
So 80 has a weight of 20.
Mrs. Guyton's class of 30 students had a mean score of 90.
So 90 has a weight of 30.
Overall, what was the mean score for all students on the quiz
The mean score for all students on the quiz was 86.
Answer:
x=136
Step-by-step explanation:
The sum of the angles inside a quadrilateral add to 360, so
79+55+110+x=360
Combine like terms
224+x=360
Subtract 224 from both sides
x=136
The answer is the option b. 1.
Two sides and one angle determine one unique triangle.
If the angle is the between the two sides, you just can use the rule known as SAS, Side Angle Side.
When that is the case you use the cosine rule.
When the known angle is not between the two sides but one of the others, you use sine theorem.
Then in any case when you know two sides and one angle of a triangle the other side and angles are determined, which implies that there is only one possible triangle.
