Answer:
C
Step-by-step explanation:
Using Pythagoras' identity in the right triangle
c² = 4² + 5² = 16 + 25 = 41 ( take the square root of both sides )
c =
← exact solution → C
Answer:
Diagram 1
Step-by-step explanation:
This diagram does not represent a function because the x value 6 is outputting 2 different y values, 4 and 6. This goes directly against the rules of a function.
Answer:
mean is equal to 5.12
Step-by-step explanation:
<em>We are given that 32% of college students work fulltime. We have to find the mean for the number of student s who are working full time in a sample of 16</em>
success rate, p = 32% = 0.32
Sample size is denoted as n = 16
The forumla of mean is given as
mean = sample size × success rate
mean = n × p
= 16 × 0.32
= 5.12
Answer:

Step-by-step explanation:
So we want to simplify:

Note that this is in the format:

And we know that this is the same as:

Let 2√5 be a and let √3 be b. Thus:

Simplify:

And this cannot be simplified any further.
Answer:
The second, and fourth choices are true.
Step-by-step explanation:
The symbol < means less than so the arrow will point to the LEFT.
Also -1/4 will not be a part of the solution. because the sign is less than.
Because the inequality is less than there will be an open circle at -1/4.
