Answer:

The measure of angle b is 15 degrees,

Step-by-step explanation:

Both triangles are isosceles. The inside one is also a right triangle. Since the big triangle is isosceles and the two angles add up to 120 degrees, they also have to be equal, meaning ∠P≅∠R=60 degrees. The inside triangle is also isosceles, meaning that m∠a=60°-b, which 60°-b representing the measure of the last angle in the smaller triangle. Since ∠a and the third angle are congruent, they each have to equal 45°. 60°-45°=15°. The measure of ∠b=15°.

Answer:

For significance levels lower than 0.07, the null hypothesis would be rejected.

Step-by-step explanation:

Decision regarding the null hypothesis:

The decision depends on the p-value of the test.

If the p-value of the test is less than the significance level, the null hypothesis is reject.

If the p-value of the test is more than the significance level, the null hypothesis is not reject.

The analyst reported a p-value of 0.07. For what significance level of will the null hypothesis would be rejected?

From the theory above, for significance levels lower than 0.07, the null hypothesis would be rejected.

Answer:

Absolute value means how far are you from zero on the number line.

absolute value of | -18| for example is 18

this means that you are at -18 on the number line that is 18 points away from zero.

and absolute value of |18 | is 18

this means that you are at point 18 on the positive direction on the number line. That is 18 points away from zero.
