Hello There!

The slope is the change in y over the change in x

In the table as y goes up 4 x goes up 1

so the slope is 4/1 or 4

Answer:

A

Step-by-step explanation:

The answer is a because essentially what it's asking for is the y intercept.

it gives us what the value of y = 1 so all we have to do is find the constant rate of change which is 3 and subtract that from 8

8-3=5 so your answer is A

Answer:

42.5

Step-by-step explanation:

First, you should find the area of the the total figure, this being a rectangle (Two of the four corners are folded over). To do this, you must multiply 9 (the length) by the height of the shape, which is 3.5 + 2 (5.5). Next, you should subtract the area of each triangle that is folded over, the area of the bottom left triangle being 2 and the area of the bottom right triangle being 5. This should bring your answer to an area of 42.5

Hope this helps :)

Answer:

A) only figure 1 and figure 2

Step-by-step explanation:

Answer: Choice A) only figure 1 and figure 2

===========================================================

Explanation:

Let's assume that figure 2 is similar to figure 3.

If this is the case, then the horizontal portions would divide to 30/15 = 2, showing that figure 3 has sides that are twice as long compared to figure 2. But then notice that the vertical sides divide to 36/24 = 1.5, which doesn't match with the previous result of 2.

Figures 2 and 3 cannot be similar for that reason.

Also, figures 1 and 3 are not similar either. Note the horizontal portions divide to 30/10 = 3 while the vertical portions divide to 36/16 = 2.25; the results 3 and 2.25 don't match.

We eliminate answers B, C and D. The only thing left is choice A.

-------------------

To verify choice A is true, we divide each corresponding piece like so

Each division leads to the same result of 1.5, meaning that figure 2's side lengths are 1.5 times longer than the corresponding side lengths of figure 1. So this confirms that figure 1 is similar to figure 2.

[tex]y=-2\\[/tex]

Step-by-step explanation:

Use the values of the unit circle to get the (x,y) when Θ=[tex]\frac{11\pi}{6}[/tex], which is [tex](\frac{\sqrt{3}}{2}, -\frac{1}{2})[/tex].

The cosecant (csc) function is the reciprocal of the sine function, so we take the y value and take the reciprocal of it, which is -2.

The probability that at least 1 doesn't use a computer at work is 0.8065.

The probability that all 5 use a computer in their jobs is 0.1935.

Suppose we let X represent the no. of women that make use of computers at work. A given random variable X which approaches a binomial distribution with the following data n = 5 and p = 0.72 has a probability function:

[tex]\mathbf{P(X=x) = \left \{ {{(^5_x)(0.72)^x(0.28)^{5-x}, \ X = 0,1,2,...5} \atop {0, \ \ \ \ \ \ \ \ \ \ \ \ elsewhere }} \right.}[/tex]

a.)

Then, the probability that at least 1 doesn't use a computer at work can be computed as:
[tex]\mathbf{1-P(X=5) =1 - (^5_5)(0.72)^5(0.28)^{5-5}}[/tex]

[tex]\mathbf{1-P(X=5) =1 - (0.72)^5}[/tex]

[tex]\mathbf{1-P(X=5) =1 - 0.1935}[/tex]

⇒ 0.8065

b.)

The probability that all 5 make use of computers at their job is;
[tex]\mathbf{P(X=5) = (^5_5) (0.72)^5 (0.28)^{5-5}}[/tex]

[tex]\mathbf{P(X=5) = 1 \times (0.72)^5 \times 1}[/tex]

P(X = 5) = 0.1935

Answer:

C.–1 and 4

Step-by-step explanation:

Solving the equations  y = –x² + 4x and y = x – 4

–x² + 4x = x – 4

x² - 4x + x = 4

x² - 3x = 4

x² - 3x + (3/2)² = 4 +  (3/2)²

(x - 3/2)² = 4 +  9/4

             = 6.25

x - 3/2 = √6.25                      or  x - 3/2 = -√6.25

x = 2.5 + 1.5                                        x = -2.5 + 1.5

= 4                                                        = -1

Answer:

No, the events are not independent.

Step-by-step explanation:

Suppose that there are two events, A and B.

Such that first happens the event A and then the event B.

If the outcome of event A affects the probabilities for the different outcomes of event B, then the events are dependent.

In this case, if we have only the event "selecting a student who has brown eyes"  (at random)

The probability is equal to the quotient between the total number of students with brown eyes, and the total number of students, then this probability is:

P = 91/200 = 0.455...

Now, if we first impose the "selecting a female", now when we want to select a student with brown eyes we will look only at the female students.

In this case, there are 32 with brown eyes and a total of 90 female students, then the probability of selecting a female with brown eyes at random is:

P = 32/90 = 0.355...

So the probability is different, which means that the events "selecting a female" and "selecting a student who has brown eyes" are not independent.

Answer:

(6.0)(5.4)

Step-by-step explanation:

First we have to find the equation of the line represented in the table; for that we have to find it's slope  and it's y-intercept  and then write it in the following form:

The slope  of the line we get from first two points:

thus we have

we find  by putting the point  into the function:

Thus we have

Now we have to find where this line intersects with ; to do this we just substitute  with :

We have the x-coordinate of  the intersection.

We find the y-coordinate by substituting  into :

Answer:

x = 4, x = 8

Step-by-step explanation:

Given

(x - 7)(x - 5) = 3 ← expand factors using FOIL

x² - 12x + 35 = 3 ( subtract 3 from both sides )

x² - 12x + 32 = 0 ← in standard form

(x - 4)(x - 8) = 0 ← in factored form

Equate each factor to zero and solve for x

x - 4 = 0 ⇒ x = 4

x - 8 = 0 ⇒ x = 8

Answer:

Step-by-step explanation:

L=2W-5

A=LW, using L from above gives you

A=(2W-5)W

A=2W^2-5W

2W^2-5W-A=0, since A=33yd^2

2W^2-5W-33=0

2W^2+6W-11W-33=0

2W(W+3)-11(W+3)=0

(2W-11)(W+3)=0, since W>0

W=11/2

W=5.5yd, since L=2W-5

L=6yd

So the dimensions are W by L, 5.5yd by 6yd
