Answer:
a. 45° and 135
The non-horizontal rays of ∠ and ∠ will not intersect to form a triangle; the rays will be parallel to each other.
b. 45° and 45°
The non-horizontal rays of ∠ and ∠ will intersect to form a triangle
c. 45° and 145°
The non-horizontal rays of ∠ and ∠ will not intersect to form a triangle.

Answer:
y = 2x + 5
Step-by-step explanation:
First, find the slope using rise over run, (y2 - y1) / (x2 - x1)
With this information, we can create 2 points: (2, 9) and (5, 15)
Plug in the points:
(15 - 9) / (5 - 2)
6 / 3
= 2
Plug in the slope and a point into y = mx + b, and solve for b:
y = mx + b
15 = 2(5) + b
15 = 10 + b
5 = b
Plug in the slope and b into the equation:
y = 2x + 5 is the equation of the line
Answer:
H0 : mu1 = mu2
Ha : mu1 ≠ mu2
Which means
Null hypothesis H0; the true mean price when buying from a friend mu1 and the true mean price when buying from a stranger mu2 is the same/equal
Alternative hypothesis Ha; the true mean price when buying from a friend mu1 and the true mean price when buying from a stranger mu2 is different (not equal)
Step-by-step explanation:
The null hypothesis (H0) tries to show that no significant variation exists between variables or that a single variable is no different than its mean(i.e it tries to prove that the old theory is true). While an alternative Hypothesis (Ha) attempt to prove that a new theory is true rather than the old one. That a variable is significantly different from the mean.
Therefore, for the case above;
H0 : mu1 = mu2
Ha : mu1 ≠ mu2
Which means
Null hypothesis H0; the true mean price when buying from a friend mu1 and the true mean price when buying from a stranger mu2 is the same/equal
Alternative hypothesis Ha; the true mean price when buying from a friend mu1 and the true mean price when buying from a stranger mu2 is different (not equal)
1/6³ is simply multiplying the fraction 3 times.
or the numerator 3 times and the denominator 3 times.
It can be: 1/6 * 1/6 * 1/6 = <u>1 * 1 * 1 </u> = <u> 1 </u>
6 * 6 * 6 216<u />
or <u> 1³ </u> = <u> 1 </u>
6³ 216
