Answer:

1. C

2. B

3. B

Step-by-step explanation:

Vertical angles are the angles opposite each other when two lines cross, thus angles with measures (x+77)° and 126° are vertical angles.

Vertical angles are congruent.

Hence,

$x+77=126\\ \\x=126-77\\ \\x=49^{\circ}$

Which of the following is the line of symmetry for the figure shown below?

scoray [572]

Answer:

Line A

Step-by-step explanation:

A line of symmetry is a line that divides a shape into exactly two equal halves.

A triangle is a polygon with three sides and three angles. A scalene triangle has no lines of symmetry, an isosceles triangle has more than one line of symmetry while an equilateral triangle has three lines of symmetry.

From the diagram we can see that line A divides the figure into two equal halves, hence line A is the line of symmetry.

A graduate-level computer science course only gives the grades of A, B, or C. The department has determined that there should be

kupik [55]

Step-by-step explanation:

The null hypothesis: The department has determined that there should be 40% A’s given, 40% B’s given and 20% C’s given as final grades for the course

If the p-value for this hypothesis test is = 0.000... and this number is lower than the 0.05 significance level, we reject the null hypothesis and conclude that from the result of our observation that final grades do not match this grading guidelines.

It means the grading guidelines was exceeded in terms of As, was less in terms of Bs and was higher in terms of Cs i e the grading guidelines was not consistent with what was stated in the null.
