Answer:

2.41 * n = y

Step-by-step explanation:

From the table, we can notice that the value;

y/n is a constant for each of the rows

this represents the individual costs of each of the books

So, we have it that;

7.23/3 = 4.82/2 = 9.64/4 = $2.41

So, the books have a unit cost of $2.41

Hence, by multiplying the number of books n by 2.41 we can get the cost y

So mathematically, we have the relation as;

2.41 * n = y

Answer:

Axis of symmetry: x=-4

Step-by-step explanation:

If x=-7 and x=-1 are solutions to a quadratic equation, then that quadratic equation must be (x+1)(x+7)=0 -> x^2+8x+7=0 as both solutions satisfy the Zero Product Property where the function is f(x)=x^2+8x+7. The axis of symmetry would be the line x=-b/2a which means the axis of symmetry is x=-(8)/2(1)=-8/2=-4 -> x=-4. It can also be found by turning f(x)=x^2+8x+7 into f(x)=(x+4)^2-9 by completing the square, and since h=-4, then the axis of symmetry would be x=h=-4. Refer to the graph.

Answer:

x=4, x=-1/2

Answer:

See below for answers and explanations (along with a graph)

Step-by-step explanation:

X-intercepts:

2x²-7x-4=0

(2x+1)(x-4)=0

2x+1=0 and x-4=0

x=-1/2 and x=4

Axis of Symmetry:

x=-b/2a

x=-(-7)/2(2)

x=7/4

Vertex:

f(x)=2x²-7x-4

f(7/4)=2(7/4)² - 7(7/4) - 4

f(7/4)=2(49/16) - 49/4 - 4

f(7/4)=98/16 - 196/16 - 64/16

f(7/4)=-162/16

(h,k) = (7/4,-81/8)

Step-by-step explanation:

Answer:

The height of any right triangle is just simply the many units that are going up but it has to start from the right angle and upwards and that would be your height.

It may already give you a height so there is no need to worry if so.

Here, in this case the side on the very left is my height:

Answer:

Use Pythagorean Theorem

Step-by-step explanation:

a²+b²=c²

You need to find the height, which means you have a and c. You square a and c, subtract a from c, then find the square root of that difference. Now you have b.

EXAMPLE:

a=3, c=6

3²+b²=6²

9+b²=36

-9        -9

b²=27

sqrt of 27 is 5.2. So the side is 5.2

Alternate interior angles are congruent, so 2x+5 = 3x -2.  X=7

Step-by-step explanation:

Answer:

A and B

Step-by-step explanation:

Adjacent angles are angles that share a common vertex

More specifically adjacent angles are next to each other.

The two angles that are next to ∠3 are ∠4 and ∠2 therefore the correct answer would be A and B

The minimum value is the lowest point of a graphed line. The would be the bottom of the "U" shape.

Looking at the graph you can see that the bottom of the U is touching the horizontal line at x = -5.5, so this would be the minimum value.

The lowest part of the line is at -5.5

Answer: 41,224

Step-by-step explanation:

Answer:

The answer is 9.0909

Step-by-step explanation:

n=1  p=.11

mean = 1/0.11 = 9.0909

The mean of X, the number of patients seen until an injection-site reaction occurs is 9.0909.

The mean refers to "the average set of values".

According to the question,

The percentage of patients experiencing injection- site reactions with the current needle is 11%.

Mean = [tex]\frac{sum of the all values}{Total number of values}[/tex]

Total number of values = 11% = 0.11 and  n = 1.

Mean = [tex]\frac{1}{0.11}[/tex]

=9.0909.

Hence, the mean of X, the number of patients seen until an injection-site reaction occurs is 9.0909.
