Answer:

25

Step-by-step explanation:

it is alternate interior

same thing

65-25=40

2×25-10=40

Answer:

-2

Step-by-step explanation:

The formula for finding the slope is y2-y1 divided by x2-x1. You can use any two points.

So,

220-240 divided by 10-0= -20/10= -2

Hope this helps!!!

Answer:

D

Step-by-step explanation:

y = a[tex]x^{2}[/tex] + bx + c  is an equation for a parabola in standard form.

y = a(x - h)² + k is the equation for a parabola in vertex form.

We use y = because the parabola opens vertically.

The vertex is the point on the curve of the parabola, so either the lowest or highest point depending on whether it opens up or down.

We are given the vertex of (1,3), is the vertex formula h is the x and k is the y.

(h,k) or in this case (1,3).

Let's substitute the vertex.

y = a(x - 1)² + 3

To find a, we use the other point (2,6) to substitute in x and y to solve.

x = 2   y = 6

6 = a(2 - 1)² + 3

6 = a(1)² + 3

6 = a(1) + 3

6 = a + 3  Subtract 3 from each side.

6 - 3 = a + 3 - 3

6 - 3 = a

3 = a    

Now we have all the elements of the equation.

a = 3

h = 1

k = 3

y = 3(x - 1)² + 3

So the answer is D.

B. $113.99

Step-by-step explanation:

Answer:

SOLUTION: Postulate 2.5 states if two points lie in a plane, then the entire line containing those points lies in that plane. Therefore, the statement is always true. ... The intersection of two planes can be a point. SOLUTION: Postulate 2.7 states if two planes intersect, then their intersection is a line.

Answer:

We need 4 workstations configurated in series as minimum to create theoretically a finished product every 3 minutes.

Step-by-step explanation:

At first we assume that assembly line is formed solely by workstations configurated in series. We must keep in mind that theoretical minimum number of workstations is equal to the sum of the task times required to create a product divided by the time taken by the assembly line to create one finished product. That is:

[tex]n = \frac{700\,s}{3\,min\times 60\,\frac{s}{min} }[/tex]

[tex]n = 3.889\,workstations[/tex]

We need 4 workstations configurated in series as minimum to create theoretically a finished product every 3 minutes.

Answer:

x=1/2y+2

Step-by-step explanation:

−4x+2y=−8

Step 1: Add -2y to both sides.

−4x+2y+−2y=−8+−2y

−4x=−2y−8

Step 2: Divide both sides by -4.

−4x

−4

=

−2y−8

−4

Step-by-step explanation:

Answer:

a)0.074

b)0.502

c)0.2114

d)0.0166

e)0.01790

f)0.9987

Step-by-step explanation:

Probability of being left handed = 0.13

Probability of being not left handed = 1-0.13 =0.87

They select a sample of five customers at random in their stores

a. The first lefty is the fifth person chosen

Probability that first lefty is the fifth person chosen =[tex]0.87 \times 0.87 \times 0.87 \times 0.87 \times 0.13=0.074[/tex]

b)There are some lefties among the 5 people=[tex]1-P(x=0)=1-0.87^5=0.502[/tex]

c)The first lefty is the second or third person=[tex]0.87 \times 0.13 + 0.87 \times 0.87 \times 0.13 =0.2114[/tex]

d)

[tex]P(x=3)=^5C_3 (0.13)^3 (0.87)^2=\frac{5!}{3!2!}(0.13)^3 (0.87)^2=0.0166[/tex]

e)

[tex]P(x\geq 3)=P(x=3)+P(x=4)+P(x=5)\\P(x\geq 3)=\frac{5!}{3!2!}(0.13)^3 (0.87)^2+\frac{5!}{4!1!}(0.13)^4(0.87)^1+\frac{5!}{5!0!}(0.13)^5 (0.87)^0=0.01790[/tex]

f)

[tex]P(x\leq 3)=P(x=0)+P(x=1)+P(x=2)+P(x=3)[/tex]

[tex]P(x\leq 3)=\frac{5!}{0!5!}(0.13)^0 (0.87)^5+\frac{5!}{4!1!}(0.13)^1(0.87)^4+\frac{5!}{2!3!}(0.13)^2 (0.87)^3+\frac{5!}{2!3!}(0.13)^3 (0.87)^2=0.9987[/tex]
