Point P is at the origin. Then Point P is moved 4 units to the right and 5 units up.
taurus [48]

Answer:

Step-by-step explanation:

The origin (x,y) is (0,0)

If its moved four units right you must add 4 to the x coordinate giving you (4,0)

Then it is moved up by 5, so you must add 5 to the y coordinate giving you

(4,5)

When Colton commutes to work the amount of time it takes him to arrive is normally distributed with a mean of 41 minutes and a s
larisa86 [58]

Answer:

The Probability that commute will be between 33 and 35 minutes to the nearest tenth =  0.0189 ≅1.89%  

Step-by-step explanation:

<u><em>Step(i)</em></u>:-

<em>Given mean of the Population(μ) = 41 minutes</em>

<em>Given standard deviation of the Population (σ) =  3 minutes</em>

<em>let  'X' be the random variable of Normal distribution</em>

Let X = 33

Z = \frac{x -mean}{S.D} =\frac{33-41}{3} = -2.66

let X = 35

Z = \frac{x -mean}{S.D} =\frac{35-41}{3} = -2

<u><em>Step(ii)</em></u>:-

The Probability that commute will be between 33 and 35 minutes to the nearest tenth

P(33≤ X≤35) = P(-2.66 ≤X≤-2)

                     = P( X≤-2) - P(X≤-2.66)

                     =  0.5 - A(-2) - (0.5 - A(-2.66)

                     =   0.5 -0.4772 - (0.5 -0.4961)  (From normal table)

                    = 0.5 -0.4772 - 0.5 +0.4961

                     = 0.4961 - 0.4772

                    = 0.0189

<em>The Probability that commute will be between 33 and 35 minutes to the nearest tenth =  0.0189 ≅1.89%                 </em>

Explain the relationship between the polynomial identities: x^2 − 1 = (x +1)(x − 1) and x^2 − a^2 =(x − a)(x +a).
Bess [88]

Answer:

So these two equation can be related by identity x^2-a^2=(x+a)(x-a)

Step-by-step explanation:

We have given equation x^2-1=(x+1)(x-1)

And x^2-a^2=(x+a)(x-a)

We know the algebraic identity a^2-b^2=(a+b)(a-b)

From this identity

x^2-1 can be written as (x+1) (x-1)

And using same identity x^2-a^2 can be written as (x-a)(x-b)

So these two equation can be related by identity x^2-a^2=(x+a)(x-a)

How to solve y=-5/2x+4, Y=-1 using substitution<br>(i need the steps not just the answer)​
dlinn [17]

Answer:

Step-by-step explanation:

- Since y = -1, we will substitute the y variable in the equation for -1.

 -1 = -5/2x + 4

- Take away 4 from both sides in order to find out what x equals so we can substitute it.

 5 = -5/2x

- turn it into a positive by multiplying each side by -1.

 -1(-5 = -5/2x) =

 5 = 5/2x

- Divide each side by 5.

 1 = 1/2x

- Multiple both sides by 2.

2 = x

- Substitute the variables.

x = 2

y = -1

-1 = -5/2(2) + 4
