Answer:
(a) 0
(b) -3/26
Step-by-step explanation:
(a)
We essentially plug 1 in for x and 2 in for y.
Our expression is
, so making the correct substitutions yields:

So, the answer for part (a) is 0.
(b)
Again, we're now plugging in 1 for x and 5 for y:

So, the answer for part (b) is -3/26.
Answer:
1, 4 complementary
2, 3 supplementary
5, 6 neither
Step-by-step explanation:
complementary angles are angles in which the sum of both is equal to 90 degrees. supplementary angles are angles in which their sum is equal to 180 degrees.

Answer: 16
Step-by-step explanation:
We follow BIMDAS.
So it becomes :
2+2×24/4 after the first step.
Then, 4+48/4
Then, 4+12
Which is 16

Hello!</h2>
The answer is:
The slope of the hill is equal to 2.
<h2>Why?</h2>
To solve the problem, we need to remember that the slope of a line, is the rate of increase or decrease of the line.
From the statement we know that the tallest peak of the roller coaster is 310 feet (y), while the roller coaster travels 155 horizontal feet (x), so, calculating we have:

Then, substituting the given information and calculating, we have:

We have that the slope of the hill is equal to 2.
Have a nice day!
There is no sufficient evidence to suggest that men and women have equal success in challenging calls. This was illustrated in the hypothesis.
<h3>How to compute the value?</h3>
It should be noted that based on the information given, P1 will be:
= 424/1436
= 0.295
P2 will be:
= 222/754
= 0.294
The value of the test statistic will be:
= (424 + 222)/(1436 + 754)
= 646/2190
= 0.2949
In this case, the value of the test statistic falls on the rejection region, therefore, there is no sufficient evidence to suggest that men and women have equal success in challenging calls.
